It's old news but apparently there's a planet thought to be made out of graphite and diamonds. I am old enough now that both the frontiers of the internet and this small blue world feel small to me, like the length of our yard and driveway once did, and my hunger only grows

I wonder what it would be like, if ever, for us to see the inconceivable gulf between stars as merely the same thing as a months long voyage between continents

there is a planet called europa it's covered with ice and below of the ice is thought to be water, melted due to planet cores are being hot.

If we go there it's I think almost guaranteed that we'll find first eucariote alliens, most likely fishes will be first eucariote alliens we'll ever encounter. Of course we might take another route.

Honestly I think we should start thinking now on how to develop strategies (and possibly bio and chemical weapons) for dealing with other more novel things like ammonia based life, which is theoretically possible as well. Of course given the size of this region of the galaxy alone I'd say the odds of us eventually discovering ice containing some organism are pretty decent provided our species doesn't die off by then. The real question is how we could try to even drill a core sample deep enough to check for biologics without contaminating it ourselves the Russian Federation is not going to be in charge of that one after Lake Vostok incident, unless they become glorious Imperial Kosmofederation of Rus by then

Nice that someone made thread about that. I not like op post much trouth, it is kinda childish with this "DIAMOND PLANTET!!!" and frog memes about "too early" which one forced mostly by people who not vey much follow actual news and science. But at least it not "NEW PLANET WITH POSSIBILITY OF LIVE DISCOVERED IN RED DWARF SYSTEM" so already I'am okay with tihs

Not long ago was proposed by ESA new mission for Neptun and Uranus: http://odinus.iaps.inaf.it/
It just talks for now, but I very hyped and very wait any Uranus and Neptune missions. I hope for NASA orbiter mission to ice giants, but well, they are in far future too

Also can't wait when TESS will start proper science work he was created for and will give results.
https://www.nasa.gov/feature/goddard/2018/nasa-s-planet-hunting-tess-catches-a-comet-before-starting-science - this is kinda last news on NASA site about it still. I dunno when it will start proper work and will start serach for potential exoplanets.

This thing about "undersurface ocen" for moon of gas and ice giants for like 10 years already forced as hell. I don't disagree with some points, but when people start seek undersurface ocean even on pluto and a lot people already thought that this is 100% fact that there exist life, it become "life/water on mars"-tier meme when every evidence and every bit of actual water on mars that exist almost everywhere in our system in some degree maded as other sensation about "NOT LONG AGO ON MARS WAS LIFE!!!"
It' be huge miracle if in this "ocean" on Europe or Enceladus we found something organic and it will make biggest sensation in makind history. However, even without it, mission to seek out underserface structure of this object is interesting, from geological point as minimum. However wide audience not interested much in something beyond LIFE. However, may say that we most probably will not find "alien fish" there - some most simple bacteria and micro creatures will be maximum luck already.

Doubt that. Changing ecosystems and dynamics are the reason why life exists in here. We have sun and day-night cycle, but titan is completely stable. It's just have no reasons for life to exist there. Probably Wikipedia can explain this better than me.

It is also not entirely inconceivable however that whatever protoforms of life cross pollinated with other objects in this system. IIRC they think our current moon-earth system is the result of a violent collision. It also would not be inconceivable that something such as say the Cretaceous–Paleogene impact or some other impact had hit with enough force to eject matter from our planet and into a flash freeze that then drifted outward and dusted other planets, or even the panspermia ideas (now largely debunked?) that life could have arisen elsewhere and the first blocks of life-like protein structures or unicellular organisms arrived here from elsewhere.

So, there's also that. Improbable? Sure. But I don't think you necessarily need independently arising life on each body in the system, just one with a particularly virulent entity capable of somehow surviving such violent impact events, deep freeze/radiation/vacuum (or perhaps even locked into some nodule from vacuum) followed by crashing into something else. Also sorry for the bydlo manner of posting, but I don't think anyone actually says things like that except journalists massively misrepresenting some research or statement for clickbait. With Mars and Europa it's not "had life" but "we think those places probably have/once had the conditions where some forms of life could have arisen"

On titan there are interesting theoretical concepts about Acrylonitrile-based life in it's liquid Ethane-Methane parts. Like imagine that one cell in size of A3 paper list and it's transparent X--DDDD. I'am not pro-chemist and biologist, I watched some documentary about it, but I only may say that all exo-biology about not Carbon-based life currently is deeeeep thory without any real things and most probably 90% of this is crap and most probably most of things about it you heared from science fiction.

Most recent and most adopted currently theory is about series of clashes, if I remeber correctly. Yes, our moon is most probably rare example of "percussion

I don't understand the obsession with exoplanets. Outside of astronomy and theory they are not that relevant, they certainly have no place in realistic human spaceflight plans. We aren't even bootstrapping yet, and people are talking about visiting other planets. It is easy to go on about how hyroponics means you won't run out of food, but the effects of microgravity on food growth is still being studied and still does nothing to the problem of soil destruction from intensive growing. How do you plan to constantly rejuvenate the relatively tiny amount of soil you can bring?

People act like we are within reach when most of the technology either doesn't exist or is currently impractical. Colonies outside of Earth are presently high school tier fantasies, extrasolar ones are even worse.

Because it gives us an actual dream and a goal beyond "just another spacewalk" so far as the masses are concerned, and we kind of require their backing for this scale of megaproject. It also means we have a solid objective so we just need to figure out how to achieve it, and knowing that these planets actually exist is still incredibly new science. IIRC we didn't even have any proofs of exoplanets (common sense aside) so it seems extremely likely there are some temperate, water carrying, non-toxic atmosphere, non-crushing gravity planets out there as well. Yeah okay the first confirmed one only happened in 1995. That was when we were kids and we're not even grizzled old men yet (I think for most of us anyway). It also gives us an actual reason to even bother with missions to Mars which, let's be frank, there's no real reason for us to even be doing otherwise.

The only real actual reason for us to even go to Mars to begin with is as preparation for far-habitation independent of Earth, since in reality there's fuckall reason to try mining it and terraforming it is vastly beyond our present or anywhere near future abilities, and I don't think it's even a scientifically interesting planet. Mars is literally just "how can we eventually send people on voyages to distant stars" tier. Besides which it would also be interesting to study other systems for example the numerous binaries and what planets are like out there.

But it's so fa beyond the phase we're at that it just bloats expectations and runs funding into the ground because people don't see any significant progress towards the colony meme. At this point it's like treating time travel as a realistic goal to work towards. However theoretically cool it might be, it's not even on the table right now.

If you actually want to get the public behind it, you need to break it down into phases that they will understand. Start with talking about bootstrapping in an off planet environment and working towards that vital part of long-range human spaceflight. Its more productive for everybody to work towards a real goal and not some fantastical pie in the sky that is generations away from even being a real scribble on a drawing board.

I don't see the question of lack of space funding or interest in space as problems that hold back space exploration. As far as I understand it, the problems that need to be solved aren't space exploration "exclusive", more efficient sources of energy, better AI systems, and so on. I suppose this means that as our economic and productive efficiency increases, so does the likelihood of breaking another space race milestone.

I also believe that a real "problem" that wasn't mentioned in the thread is that as space exploration goes further, the practical efforts will have less and less of a human face. I suppose it is hard to gain empathy or see a Rover's trials as something interesting or brave. We certainly wont see the 19th century type of aristocratic explorer who is trying to reach the North Pole for personal fame playing out in this scenario.

I don't believe an ideological war as happened in the 20th century will either push government funds into "bruteforcing" symbolic milestones in order to advance their "International Prestige" either.

I never said research shouldn't be done. Just that the public hype about them is overboard. There's plenty enough interesting things happening in Solar studies that the disparity in PR ends up throwing into a dark closet, and like it or not publicity shapes funding. People get excited about exoplanets, and extrasolar studies gets priority funding. Also, how do we hope to understand how those systems work when we barely understand the one that's right in front of us? Getting more PR into promoting steps that work on confirming existing theory rather than creating more new theory seems like the best way to get true scientific progress.

>>7751
And what happens if it ends up that the ones who cut the crap just start delivering forward steps and showing that they're achieving smaller goals that lead on to each other while the meme-spouters, even achieving the same things have achieved barely a notch towards their pie in the sky? People like results, and people seeing things being achieved again and again are going to see that as achieving more than the same thing being done but not actually hitting the proclaimed endpoint.

Did you know that this is with exoplanetary system researches we start to understand much more about creation of our solar system? Before exoplanet discoveries we thought that our system is something standart, but now we understand that it is not, and there hell lot more common scenarios and we different ways how different systems evolved we start to understand much more about how it happen that our system look like it is.
What you proposing is just cut one direction in favor of other, but things not happen like this. We will not stop researching space just because we still don't know enough about our own oceans for example. All things evolving naturally, mones and attention goes on researches in which people most interest with currently. Even if you force all people to build something that far beyod current need or intersts it will end as it started and everything will go to normal. Where is your superjet civil planes? Where austronaut moon programs? Where all that shuttles and burn and their space stations with artificial gravity? Giant Ecranoplanes? All this was made or proposed in times of col war, where people builded shit without actual reasons exept military ones or just show "how we can do". All this things was unnatural for time and currently in a musems.
I don't think there "too much" attention to exoplanets. More than that, if we talk about space, none of space reaseach agencies have enough monies or any project we need, just for some other we have any less. Like yeah, with discoveries about proposed Europa underwater ocean a lot projects for researching Titan was cut because we have now "new possible place for LIFE". I sad that proposed Metan ocean submarine probe will not happen any soon, not before Europa drill station or something, but I happy with any Europa mission as well. Recent attention to jupter with Juno mission is also a good thing. Same I interested in exoplanets - I think currently, without any memes about COLONIES or LIFE tihs is one of the most interesting research directions for now and I happy that this have any money. I can't wait for launch of Webb.

It's joe public. Trust me they're too fucking stupid for any form of this. The only way forward is to manipulate their emotions and beliefs with wild and blind enthusiasm. Do you think people like Kennedy discussed phases or orbital trajectories with these idiots? No, he simply gave optimistic blind enthusiasm "we choose to go to the moon!" That kind of rhetoric is why the current fucktard is in office. His predecessor similarly just said a lot of "hope and change" regardless if anybody had any clue what that meant. This goes back before him to things like Carter and Reagan, where the simple, factual, down to earth approach with the public does not work, it has never worked, and it will never work. You give the population too much credit. Just fill their heads with notions of walking on foreign shores, and their children walking on those shores, and perhaps they can dream of someday their family name has whole estates on some foreign planet and you'll get the necessary funding.

Things like phases of development and goals is what you tell the budgetary committee and scientists. You also give the politicians a very dumbed down version of this, since they themselves don't ever fucking bother to read, let alone understand, most of the proposals that float across their desk.

Oh and also likewise, is the problem that even if you developed a colony on Mars it is fundamentally the most extreme example of the American colonialism effect if it ever became truly independent of Earth resources, because you really can't actually govern or lay ownership over something that can take literally a decade just to send a message back and forth (extra-solar at least). This is also why we're eventually going to have to go to ideological grounds IMO because it quite simply serves no actual purpose to any power brokers here on Earth except for prestige i.e. an opportunity for dick waving, which is what the aristocrats going to the North pole or whatever tried to do. You must never forget peoples emotions are powerful motivators, like a built in drug delivery system.

the point about sending messages. i totally agree with you there.

there is no point in a centralized power/decision position, if your colony is that far spread apart that a message would take longer to deliver as the life of the generation affected by the decision. you do need decentralized, independent structures.

a "one man/organization at the very top"-scenario is simply impossible to achieve. unless, you are against human development and want to cripple us humans down. for the illusion of being in charge. quite stupid decision it would be.

Basic theory about origins of life demands not only suitable soup, but also demands "chemical activity"(I might be using the wrong term). It's not enough to put all ingredients into water and life will appear there, otherwise scientists would already have done this.

No idea. Although I'd imagine some worlds it's just completely absent, but who knows. It's not like we can send a probe there right now but the crushing temperature and heat there must surely make life as we know it completely impossible unless it's floating. Probably these worlds are filled with Ice-10 as well.

Duuno if it smart to up this thread during kohl invasion, but I want to disscus it.

Did you know about boeing 2707 project? This is USA project of 1st generation supersonic civil plane that was a competitor to Concorde and Ту-144.
It was indeed very, very expencive project. it was simplified but then canelled, when it become onbious that USA is too far from Europe and USSR who already builded and used their planes, and boths soviet and european projects showed that supersonic civil planes are useless - to dangerous, to difficult to maintain, drink too many fuel, requre bigger airfields and sonic boom was actual big problem and honestely nobody needed supersonic planes when already existed planes was much more cost-effective, much more comfort and can fill much more people in them.

While I don't find final much more simplified version of project that almost did it to be build with several prototype-test things was build, I'am much more interested in early example of it, which one totally epin. History showed that supersonic planes lost to more slow, but more logical widebody planes, initial 2707 project was AND SUPERSONIC and WIDEBODY plane, as you can see at first picture with different wide across all plane. It was also more fast than competitors with cruise speeds of approximately Mach number 3 and more big indeed - they planed module body that will be builded with variaty for 250 to 300 passengers and even more.

Most interesting thing of initial project hovewer was wings - Variable-sweep wings on this giant! And same time this beauty had 4 engines that was attached to back wings and unlike european and soviet creatons was compleatly divided. There also for it was done so many epin engeneering! Sadly that it was not enough engeneering, and later project that had more chances to become reality (on pic 2 real test build) already looked much more conservative triangle wing and more simple elements overall, but even that plane never did it.

Honestely if this plane was build, it'd be more impractical that Ту-144 and concorde and be catastrophy, whole this project almost did even such giant as boieng bacrupt, but I want this to be buid one day jsut because how cool it is.

I don't know what it did on 2707, but on other superjet planes it was for landing.
Concorde and Ту-144 had similar ones, very complicated mecahnisms but they was important. Planes with riangalare wing are very great on high speeds of near and after sonic aerodynamics, but terrible at control on low speeds and this supersonic planes have very high minimal speeds and also very sharp angle of landing. So when plane landed down, it's nose moved down. Ту-144 adittionaly had small wings that opened when plane was on low speeds for better manuvering.

Since all pics I postested exept last one are just artists interpritation of different concept plans of 2707, I can't say why it needed same things, since his very complicated modular wings had direct purpose of making boieng plane as controlable on low speeds, as just any regular plane. But I may guess since it was giant as fuck and fast as fuck, it still had potentially high low-speeds and not best controls during landing and it should help that purpose. I only can say that it hard to find many information about it. Most of it on much more later simplified version, I more interesting in original 2707 and similar pre-2707 boeing projects with this wing idea - like Model 733, from which project of 2707 would start, but for it find information even harder.

My expectation of realistic and light-speed travel starts from 10000 from now and ends to "never" so this caption may be right. However all current "projects" of interstellar travel currently is no more than just speculations to say the least and most of them unrealisitc, for hype or for joke purpose. I bet you remember when in like 2014 or 15 was popular in meadia theme of Alcubierre drive and all screamed that we will fly in starts very soon, even was picture of "possible ships" like that picture. Of cource, it all ended with nothing currently.
Needless to add that currently we are not managed to make even real projects, like artificial gravity space station like project Nautilus-X on pic2, so all talks about interstellar ships are no more than pure memes.

I wander, how much more effective can old Ту-144 can be with modern impovments? One of the most major problems with supersonic aviation was how terrible cost-effective it was, how complicated and too new for market back than. Engines, electronics, construction elements - all used most epin technologies on 70s, but nowdays in therms of engines, electronics and mechanisms and materials we are so far ahead!
Like for example, it was already shown - Ту-144ЛЛ who flied as fyling laboratory even for NASA lol, get much more new engines in 1996, НК-32-1 instead original НК-144/РД-36-51А and if you look at charasteristics, for example their thrust is like 1,5 times better than НК-144 or Concorde's Olympus 593.

And with 2018 technologies, without modern materials and electronics we can make get much more improved engines even than this НК-32-1, theoreticly like trice or more effective, not use combustors (I guess it is correct therm for Форсажная камера on english?) on start, get rid of this lowering nose mechanisms since modern electronics can land plane without involing of pilots at all, use composite modern materials and make mass of plane much more lighter, same as cost of it's production. And I shure it possible to make that it will land without help of brake chutes. And you know what? Almost all of this ideas was already put into theoretical Ту-244 project that started not long after Ту-144. So it was possible even back than, imagine what we can do now.

Yes, this plane will still will be not even near cost effective as modern pre-sonic planes, sonic boom problem will still exist, but I'am shure it will not be CATASTROPHY as first generation supersonic civil planes - with more high prices on tickets and flights across seas a oceans, like Tel Aviv-New Yourk or Tokyo-Los Angeles it will find it's use and will be much more easy to maintain and use nowdays that Concorde back than. Catastrophy of superjet civil lanes was that they was too early in my opinion, and after shock after failures, and focus on widebody twin-aisle aircrafts in civil aviation, all fear to go back to something new.

Ironic, that curent small companies (behind them often big corporations but anyway) who currently develop project of supersonic civil jets making them small, buisness jet planes for rich fucks. It logical move, cinsidering that they are minimising the riscs. But I belive, that if anyone nowdays start proper project of big supersonic civil plane, even on base of Ту-244 or even fucking Boeing-2707 but with modern engines, electronics and materials - they will already be enough cost effective and not that loud and much more easy to maintian, just everybody fear to risk even thought there not much risks nowdays. And look, unlike Aerion SBJ by Areon corporation (in reality this is just Lokhed Martin/Airbus project I think they just created separate company for it) that making very unortodox civil plane that tchnically more like F-104 starfighter, Boom technology making .. (pic3) what a coincedence, small copy of Ту-144/Concorde/late Boeing-2707! Not so catactrophic failure already, huh?

There wont be a significant amount of supersonic planes in the foreseeable future, if any. Perhaps half a dozen being used at most in the near future.
The concorde itself was extremely expensive and wasn't even profitable. The operating costs were lower than the revenue, but this does not include all of the development cost.

The future is also here and I can assure you it's going to be terrible. It will always be the same incompetence, dystopia, and merchants/nobles class scum toadying up to some even more deplorable emperor with a bunch of dumbass thugs roaming around abusing the citizenry. It is exactly the same in every century. I don't like anything that ends up amplifying those powers, and sadly I expect this to do exactly that. Why the fuck would you even want a self driving car to begin with? It is one of the few things left where you're supposed to have at least some privacy and control. I have no idea why the fuck people are fine with handing this over to huge dystopian corporations too.

As I posted, many of this issues was problems of materials and technologies of it's time. At start of Jet engines and jet aviation it had exeact same problems: too much cost, too low resource of engine, eat many fuel. It requred a lot of years to make them profitable. Experiments with it was even in 20s, but first commercial jet planes started developed in 40s, and only in 50s DeHavelant Comet appeared, and it more fail that victory considering how much problems it get and same as supersonic jets at one point was just closed after some crashes. However, because it, Douglas DS8 and Ту-104 and Boeing 707 that came after can avoid most of this initial problems, but even this, 2nd generation of civil jet planes not lived too long to be replaced with much better ones only after 5 years or so.

Not all of problems of supersonic planes are resolved, but they much, much more technologically now. Even 80s projects that no did it because - like Ту-244, was already in many ways more rentable and logical. Only 10 years after first generation, was already created technologies that might make this planes much more sucsessfull. This what I said in previous post - ew electronics, new engines, new materials. If supersonic jet projects of 80s did it, they'd had no this overcomplicated moving nose on landing, have less requrements and less personell for piloting and maintain, have bigger resource and was silent, but in 80s nobody wanted it because marcet and politics and initial dissapointment and hype about wide-body planes.

However already in 90s boeing re-started someprojects, like this boeing sonic cruser. This plane meant to be fly on trans-sonic speeds. Project was mainly cancelled because events of 9/11, problems in market of civil aviation afterwards and all related shit. At 2018 most problems with such projects just as many because they started not as good as original first jet planes did and everybody fear to loose money on something new, espessialy big companies. But small companies with big corporations behind them very actively working on supersonic buisnes jets. This is segment in which market most shure, since small buisness jets most probably be even more cost effective and less dissapointment if they fail than if full scale large, multi-passenger aircraft did so.

Like this Aerion SBJ I talked about - very promesing and in many ways very fresh conceptualy project. Well, fresh for civil planes, but already known for military aviation. This trapezoidal wing, back engine arrangement, most modern aerodynamics, most modern materials and technologies and allso not very big scale of plane will reduce problems of sonic boom to minimum. Giant of Lokhed Martin behind this samm company and they promesing that project more or less be done in mid 20s and first supersonic buiseness jets appear at companies service. I belive that this time it is most safe and guaranteed sucsess, and after it bigger variants will be only question of "how soon". I so shure about it because as I said already, supersonic jets already may be sucsess in 80s technologies, and we now far ahead of 80s.

Emm... I can not agree there since they are equally more interesting. Yes, one big balls of water where instead of bottom is Ice-VII is interesting thing, but such worlds don't mean any life, and also not most unique objects in space.
Solid planets that heaver and bigger than earth is interesting things. There are examples of really heavy giants and this objects is something we absoluetly can not see in our system, where earth is the biggest of the type. Same we can not see some interesting orbits such planets can rotate around their stars.

Here's just a snippet

> Hundreds of thousands of years ago, our ancestors were infected by a retrovirus. Now, some researchers think that that virus' ancient genetic traces still present in some people's genomes are silently promoting addictive behavior.

>Genetic traces of a retrovirus called HK2 is more commonly found in people with drug addictions than those without addictions, and these traces may influence surrounding genes , which, in turn, might influence human behavior, an international group of researchers reported today (Sept. 24) in the journal Proceedings of the National Academy of Sciences.

>Retroviruses — which include HK2 as well as human immunodeficiency virus (HIV) — are viruses that can insert their genetic code into their hosts' DNA. It's thought that around 5 to 8 percent of the human genome is filled with traces of ancient retroviruses that found their way into our genes by infecting our ancestors eons ago
You should read the full article it's pretty interesting. This also begs the question of how many abnormal human behaviors or elements of our evolution can be traced back to virus RNA

I think this is right place to talk about cars.

Citroën DS is one of the most memorable cars in history and probably most famous french car. Espessially more late models with head lights like pic related. I love how classic french cars most often had really interesting and artistic desighn and knowing that this is 50s car which development started even before war, and in some elements it still look modern and futuristic! Iternaly it was very futuristic too with it's front-wheel drive combined with hydropneumatic suspension, hell lot of plastic and sintetic materials, very unitrodox brakes, without even a proper pedal but with button and many things like this. Not something really on science fiction level but for it's time really great example when engeneers free to do something they relly want instead of what general audience want. In all ways, very iconic car, I want one day try test drive one of those.

EEH 2CV is really famous and memetic car, but can it really be face of all French authomobile industry? I don't know. DS is much more presentable car, let's say this way. And was 2CV THAT popular compare to other "cheap popular automobile for people"? Beetle you see everywhere, it was in production in latin america countries, you can spot it USA, middle east, across all europe, africa. 2CV - inside france and it's colonies/former colonies yeah, pretty much, but I even more often see some soviet cars in old europen photos than 2CV, in England for example.

However this is nice little car, very simple and kinda "boring" but same time memorable looking. Desighn of it reminds of like it something taken off from kitchen, lol, like grater. But question is - is this really was this economical? It still requre a lot metal and a lot other material to produce. I don't know if it was really that reasonable to make overall construction that simple.

From gendarme series of movies much more memorable Citroën Méhari, 2CV variant, exeacly like one from 4th pic as basicly main car Gendarmes using thought all movies.

Funny thing that with all this nobody remembered that in first movie was pre-production ford mustang.

No. You're retroactively applying current breakthroughs in tech to perceived future tech which is derived from past science fiction and then applying it to the extremely distant past in antiquity. Humans are more prone to using fiction as a roadmap for what kind of things to develop. For instance we have had notions of cloaking fields for quite some time, in for example the Predator movies from the 1980s, and they in turn are arguably influenced by fiction such as The Invisible Man where the means itself was never the point of the story or perhaps something from Lovecraft like Shadow Out of Time or Color Out of Space (I keep mixing those two up). That we now have some publicly known candidates for light bending material doesn't make those stories true. Likewise everybody now has what look like tricorders glued to their faces. I think this is less a matter of Roddenburry being prophetic and more a matter of human technical progress being partly guided by pop culture references because they think "that's what the future should be like" and assume "that's what modern tech should look like".

In fact the whole idea of tractor beams is pretty retarded. The concept I think is derived from a deus ex machina in stage plays wherein an actor or object would be hoisted by wire while having stage lights used to represent the "invisible force" which in a prior age would simply be the force of God's will ascending you up to Heaven like Elijah or Enoch or somesuch. Indeed, in a very real sense the whole realm of UFOlogy is basically just religion for a more cynical, skeptical, technically inclined modern society for whom "it's magic yo I ain't gotta explain shit" is no longer justification but will still go along with it and suspend disbelief so long as you invent some phlebotinum or ridiculous premise like "it's midichlorians yo they used eleriumite to levitate and cast lightningballs out of their arse"

It is also funny when you look into some of the more retarded things people used to believe in with some quack scientific sounding justification like "animal magnetism" or that the moon's rays had unique healing and powerful properties or certain alchemical ideas many of which were washed away with the dross of a previous age before becoming the modern field of chemistry some time ago.

Dunno where better post it - in history thread, or in science and technology, but let's talk about experemental and lessr known Soviet/Russian small arms projects that not did it into mass production. There a lot of different interesting and obscure examples about which not much information remain and about which not much people know about.

And I want start from Kalashnikov's competitors (yes, there was and there was a lot of them with a lot similar and yet different ideas, and while there a lot meme forced about "AK is copy of Sturmgewehr" which is not real, thing that Kalashnikov picked hell lot of ideas from it's competitors and that USSR used german stamping technology to produce AK parts and using some ideas even from things like M1 Garand is true to some degree).

Let's start from most epin things - ТКБ-408 (picture 1 - ТКБ-408-2, picture 2 - ТКБ-408 field disassembly) by German Alexandrovichj Korobov. ТКБ abbreviation means not that it is by Korobov, but basicly stands for Tula Design/Construction Bureau. Korobov is kind of famous meme guy in russian firearms history - he done a lot things, creaed a lot concepts and helped other famous weapon makes with different details, but none of his desgihns trought whole history of his work was never adopted by any degree. Of cource you may see that very interesting feature of this assault rifle that this is a bullpupб which in late 40s was really fresh and interesting concepts (there was examples before, but you know, it was even more obscure and experemental thing) - if I remember only british guys really hugely experemented with this concept at the time, in britain were build different examples of such guns -some good, some not that much, best by far was final iteration of EM-2 https://en.wikipedia.org/wiki/EM-2_rifle which was even adopted, untill Churchill become main guy angain and blah-blah-blah, politics, it was srapped in favor of FNFAL if I remember correctly because NATO. This ТКБ-408 of cource did not done it in competition - not best firing accuracy, and really not that well relability - low survivability of the receiver, shooting delays, so after 5000 shots it left competition.

АБ-46 (Production index ТКБ-415) - (picture 3 - top early variant, bottom late variant, picture 4 - field dissasembly) Assault Rifle created for competition by Alexey Alexeevich Bulking. He developed things for this competition and similar ones since middle of world war 2 - there known some examples of his work in 1944, but overall Bulkin is very misterious person. Almost all information about him and his work was lost with personal files. There like one personal foto that go around, and most of information about him - with this assault rifles he developed in late 40s. By many things, this was really close to Kalashnikov's example. it had some issues with relability and functioning, but overall it was as good as AK. Most notably, it used as asis many similar to AK ideas, like some small things from Garand. Overall, it was rejected because there was no way to improve reliability without compleatly changing elelemnts of construction.
This is not 100% confirmed facts, sine hell lot of documents still secret or lost, but in 1946 tests Kalashnikov's rifle left competition, but Kalashnikov and basicly all Kovrov factory was huge connections with some commission officers that run competition, and they agreed to give time for Kovrov to improve their rifle. Nexy year Kalashnikov with support of Zaitsev at Kovrov factory improved their rifle - by many way, just stealing best elements of Bulkin's automatic rifle. Also I readed somewhere that most probably Bukin died same time and was not alive to last series of competition, and it ended like this: Bulkin deda. Kovrov factory have huge political impact on competition. New AK example have best Bulkin elements in it, combined with other good elements of AK-46 example. And Kalashnikov won, end of story.

АД-46 (production index КБП-410) - (picture 1, picture 2 folding stock variant, picture 3 field dissasembly) - Assault rifle prototype by Alexander Andreevich Dementiev he made for same competition. Dementiev not very known guy, but before and trought war he very closely worked with such famous guys as Shpagin and Degtyaryov and basicly they was kinda same team. This example of assult rifles did it to tests of 1946, together with AK-46 and AБ-46. As with Bulkin, there hell lot of foggy things - many of information secret and overall about this competition more conspiracy theories that about Kennedy Assasination. The overall layout with the location of the gas piston above the barrel and the manufacturing technology of the main parts by the method of cold stamping was almost similar to the German Sturmgewehr of cource, but there was also a number of notable elements like fully enclosed stamped receiver with a thickness of 1.2 mm with a riveted neck of the magazine. I not heared 100% explanations about why it was rejected, altrought in 1946 competition all examples was regected (and kalashnikov's example was the worst one lol) so there most probably was a couple issues, but anywhay this desighn not lead anywhere. Exept only if Kalashnikov in next year stealed elements from here too, lol.

And of cource I should metion АК-46/АК-47 - test variants of later in 1949 adopted AK by Michail Kalshnikov. Initial 1946 prototypes (on last picture, top - first example, middle second example, third example was shorten version of 2nd one http://www.ak-info.ru/ak/akhstr/akhstr003.jpg bottom first test example of AK-47) was build on basis of Kalashnikov's 1944 self-loading rifle that had a lot important elements from American garand (automatic with short stroke gas piston located above the barrel and the rotating bolt, similar to that of the Garand system). It did really bad on competition, and was the worst from 1946 competition examples. 1947 variant had almost no similarities with 1946 version. AK-47 is basicly - Zaitsev help+stealing parts from Bulkin and probably Dementiev variants. Note that AK-47 IS NOT PROUCTION VARIANT. It is have at liest 5 or 6 different improvements series trought 1947 and 1948. First production guns was amde in 1948 and was adopted by soviet army as just AK in 1949. And even after 1949 there was hell lot of improvements - most of which, with manufacturing tooling, and basicly famous "AK THAT SO AWESOME IT CAN DO ANYTHING" it AKM (M means Modified) adopted in 1959. If you interesting in evolution of production like AK from 1949 but before AKM - here is interesting videos https://www.youtube.com/watch?v=zFagaHLuekQ&t=7s https://www.youtube.com/watch?v=dL-1dauhH6M
Note, that author using western terminology for this guns, that sometimes may be not official, like there no such thing as "Type II", n official documents it was metioned Lightweight 7.62-mm Kalashnikov's automat and was not marked as some new model.

ТКБ-022 - oh so this is a beasts. Korobov did comeback with his Bullpup ideas in ealy 60s with this seres of very different and obscure prototypes of assault rifles. There was a couple of competitions in early 60s after adoption of AKM in search of new guns - with new automatic components, new characteristics and so on, basicly in trought that there something more modern should come recently, with new advantages and ideas. Korobov created a lot of prototypes for basicly all this competitions.

First one is of cource what we know as just "ТКБ-022" what you can see on first picture. Yes, an assault rifle with Magazine that also plays role of kind of pistol grip. I can only suspect how uncomfortable to shoot from it, but on testings it did very well in therms of relability. However it used many new materials, was short, more light to carry and all other things that become important in modern times military.

For dedicated competition where was declarated some more concretic ideas of "future" firearm, Korobov developed a new version of his gun based on previous one, it was designated ТКБ-022П and you can see example of it on second picture. It has now proper pistol grip and more like traditional bullpup, however a lot ideas of previous gun was remained here - wide use of new materials, plastic cover in particular, light weight, shortness etc.

To improve different characteristics, such as accuracy of fire from unstable position, he made even more improved version of it, ТКБ-022ПМ, which you can see on pictures 3 and 4. With magazine really far back it was really compact, short and light weapon that for time of it's creation was indeed very awesome. However all this program ended with basicly nothing - from part of practical reasons, such as some problems with overall conception of bullpup and obscurety of it, not actual serious need to replacing AKs but for many parts political reasons of high military stuff was pretty conservative and had scepsis about adopting such crazy new concept weapon as military standart. However I may gess that many thing played with replacement of Khrushov by Breznev and in many ways change of cource of country to different direction, and cancel of many interesting civil and military programs.

Another guy who was involved in this ideas of new ultra-modern assault rifle in ealry 60s was Nikolai Afanasyev, who also created very interesting bullpup desighn of assault rifle.

Series of ТКБ-011 is really crazy stuff. Fom basic, Afanasyev picked some basic ideas from Korobov - like bullpup, usage of new materials, but overall iternaly it was compleatly different concept. Back part of the receiver attached at an angle, and exept some minor technical explanation I did not found information about how it actually suposed to work and why the hell it was done in the first place, but it indeed looks very obscure and cool. Trought it's history of development there was a couple of different versions with improvments. Of cource, with close of all program, this all lead to nowhere and now all of it's examples is in musem. from what I heared, it have typical to bullpup problems, but overall it worked and worked pretty well. On most late version that on 2nd picture, that had a lot of improvments, was made 50 round magazine, for test gun made from AK/AKM parts magazines. On some test guns was used wooden parts, but production one was proposed as fully plastic ones. Later, Afanasyev developed more concepts, but they was more or less traditional... espesially compare to this beasts.

Bullpup is great until the large group of users in the army end up with faces full of hot casings because they eject to the right. We use one in our army and from what I understand it makes logistics worse because we need to stock conversion kits for lefties because casings in the face is actually a problem compared to where they would eject in a traditional layout. Plus the ergonomics are worse for a standard rifle. It's more awkward to load in most situations and in the case of the final form of the TKB-022 there isn't much room to get a good grip with the second hand so ergonomics fail again. At best it'd see use as a crew weapon or with special forces.

Most likely to lengthen the barrel without lengthening the weapon by shifting the firing mechanism back and filling the space with more barrel. The reason for the curve itself is probably ergonomics, it's a lot easier to sight down a weapon where the business end sits a little bit above the bit that rests on your shoulder since you don't have to bring it up so far to your eye, you see it in a less extreme form on the FN SCAR. Depending on the magic that they put in it, it could also lessen recoil impact by moving some of the force downwards instead of straight back into the user.

It's still no kraut space magic, but what is?

They're not so bad so long as you're off the ground. Standing or on a knee they're only slightly more awkward and it's alleviated with practice. Problem is that if you're laying down you have to either roll onto your side some and create clearance to the side to load it or put the weapon into an unreadied position. It's a lot easier when the magazine isn't sitting practically under your body.

We had no such problem. Untill mid 80 all people in school re-learmed from left hand to right one sometimes by force and pumishments for couple of reasons but most important unspoken one - yes, since everyone was potential meat to protect fatherland from evil hordes of capitalism :---DDD

>Plus the ergonomics are worse for a standard rifle.
Most ergonomical and probably best mass-army service bullpup ever was French FAMAS (pic 1). It was really nice to carry, plesant to shoot as I know and other good things, like it had really really nice bipod that allow verry accurate and even more plesant shoot. Burst mode on it was really nice too. Sad that french stop development of it.

>At best it'd see use as a crew weapon or with special forces.
The only bullpup that was managed to be accepted to some degree in USSR/Russia - ОЦ-14 "Гроза" (pic 1-3) ended in different kinds of special forces. This is basicly ОЦ-12 Тисс (АКС74У made into СП-5 СП-6 9×39 sub-sonic ammunition that also used in other soviet and russian special forces weapons such as ВСС Винторез and АС Вал) made into bullpup. Most interesting part of desighn that this is comolex of weapon with underbarrel grenade launcher and also with ability to quikly change barrel for different types of tactical situation. As I know for what it meant to be primary used - with grenade launcher - it pretty balanced. Creator of this underbarrel grenade launchers for AK did part in developing ОЦ-14 Гроза. But of cource this thing is clearly not for general conscript use.

So, it's time for space magic!

During 2nd half of XX centuary in light automatic firearms was a lot talks about to have multiple bullets shit before recoil of the first round hit the shooter and break accuracy. There was many ideas how to do it and most of them, together with this progams, ended to nothing. In USA was a lot experementation with multiple bullets in one round. USSR done experementation with multiple barrels. And there we again do a comback to Korobov.

Absoluetly epic Three-barrel ТКБ-059 (pics 1-2) was developed to kinda multi purpose - same time for idea of shoot three bullets same time before recoil hit, and for massive salvo fire. Of cource, this is very questionable thing for practic use and for manufacturing. Unlike other Korobov guns there wass used parts from AK, but well, you can guess that in 1962-63 it lead to nowhere.

But idea still float around, and competitions continued. In late 70s Korobov after series of experements from late 60s to early 70s presented ТКБ-0111 (pics 3) which was presented for "Абакан" program, which was sterted after accpet of AK-74 and move to 5.45х39mm. This program had more general goal - AK had not enough firing accuracy in automatic with thoeretical modern warfare needs. From what I understand, real features of this assault rifle was just 3-round burst fire and interesting construction of muzzle brake compensator, and this all. Army looked at it and said litteraly "meh", or to say how it was listed in documents - "recommended in facultative (optional) order" whatever it means..

Most interesting from early examples of this competitions done Stechkin - ТКБ-0146 (picture 4). I think you familiar with Stechkin as author of very famous series of soviet pistols, but here he did automatic rifle, and did it bullpup! More than that, it did many awesome thing - 2-round very fast fire burst with interesting feeding system where 2nd round have place in kinda half way from magazine to chamber. Interesting egection poart, which is ambidextrous, which as was metion before in thread, very important thing for modern bullpup. It almost did it and win, but Nikonov who stealed some cool parts from previously metioned examples created rifle that was ended adopted (sounds familiar, right?) to some degree and Stechkin's gun reamined only in musems... however, it not as sad as with Korobov, since Stechkin have a lot other guns that was actually adopted, while Korobov just died without any degree of fame.

Fair enough then. I was going to talk about the Groza in contrast to the TKB-022 since the former had the advantage of adaptability while the latter was designed to do one thing but I deemed it a bit too much of a tangent. The adaptability is big though. In our case, the special forces use M4s and things of that nature because they're far easier to modify to fit the situation they're going into than the AUG. Admittedly our version of the AUG is more adaptable than the base model, but it's still relatively rigid in its design.

I'm personally of the belief that bullpup design will be outdated eventually. Once they crack the puzzle of making toploading like the G11 and P90 easy to build and reliable, it's just a plain superior system. It allows for the full length barrel in a smaller package that the bullpup gives without the ergonomic disadvantages.

And yeah, I know the Soviets have their space magic, but I have yet to see anything that tops the kraut magic of feeding multiple rounds, rotating them 90 degrees and firing them in a fraction of a second. Even seeing vaguely how it works, it's still just magic when you try to wrap your heda around it because it could put out a burst of fire before you felt the recoil which was its main way of maintaining accuracy.

I don't get the two-round burst thing. It's so uniquely slavic, since it's also on the AN-94 yeah? Is there some particular reason for it that I'm missing or is it more that the competition would specify two round accuracy and so everybody just made two round bursts and made them as accurate as possible.

The AN-94 is also Slavic Space Magic all things considered though. It's even got a mechanism brick not dissimilar to how the G11 was laid out internally. It's just less Germanic autism in clockwork and more Russian weirdness in somehow integrating a pulley into an automatic rifle :-DDD

Ironically P90 as I know considering outdated and replaced by MP-7, at least I heared such thing a couple of yeras before. But even there I can say that crazy ivan ingeneering can offer here! But wait, I can't post so fast X---DDDD

>>13273
Well, here you triggered me, lol. I wanted to post it later, but now I want to make post about it immideatly.

Anothe guy who was in competition - Gennadyi Nikonov. In 80s he offered his "АС" (pic 1) (I guess it stands just for Автомат Специальный). And main goal of his work was to offer two fire burst...

but I need to exaplain there more a little bit. This is not standart burst fire mode which you can see in FAMAS or SCAR or any other this kind of thing. This is continuation of this long time worldwide search of fire more bullets before recoil of first one hit the shooter. All this multiple barrel guns, all this USA experements with multiple bullets in one round and all this crazy shit was done for this but at end, amlost all gived up.
But Nikonov wanted to offer this feature not with multiple barrels - but with very fast, like lighning speed fire burst, so this is not burst basicly - you fire 2 bullets in time human can't even tell it was two bullets or one. By time recoil of first shot hit shooter, second bullet already hit target together with first one.

Well, first example of rifle he offered was not the best, since to offer proper feeding for this kind of speed he made and barrel and magazine moving with fire of gun. Yeah, this parts was moving while you shoot, like it some sort of canon. Even Nikonov hismelf know that it was not best idea but he not come up with something better at that time. Latter, at competition he spotted alredy metioned above examples of Stechkin and Korobov guns, and taked from them interesting ideas. From Stechkin gun he used this awesome feeding system where first round in chaber, third in magazine, and second is special place between for ultra speed feeding. And muzzle brake compensator from Korobov example for this competition. With this new parts, he presented new example - АСМ (picture 2), with this new compensator and feeding mechanism, which allowed to make fixed magazine. Trought, barrel was still moving mechanism and it remained like this.

After series of competitions, fall of soviet union, polisihng of examples in early 90s was accepted final form of this rifle - АН-94 (picture 3) that was accepted for special forces and become one of the iconic gun because some videogames. Full name of it - АН-94 Абакан, it righfully get name from river, on which was named this more than 20 years competition. Trought, in most videogames it not work right, for example in Stalker and in some battlefield games - it is rare when showed real feature of this gun "super speed 2 round fire"

So there is two very interesting videos
Disassambeling and some infor about this gun from Ian (of non-functional civil model for assburgers. This is not deactivated, since it was builed deactived on factory. You can buy still one like this for like ~5286 USA, at least on russian internet shops):
https://www.youtube.com/watch?v=gtMssTSnRHU
Example of this "two round" shooting because better see than try to exaplin it by words:
https://www.youtube.com/watch?v=m5aEfe1cCls

Another gun what I want metion in this post - АО63. It was another gun in this competition, I know not much about it... but from what I heared and seen this is just two-barrel АК-74. Nothing patriculray anything about, since it continuation of Korobov multi-barrel concept that was rejected multiple times and not as epin as ТКБ-059 anyway. There is meme when to show this gun in american Red Scorpion movie was used poor FN FAL turned into some monster, and oftent picture of this gun presented in internet as real АО63, which, of cource, is not http://www.imfdb.org/images/1/15/Red_Scorpion_AO-63.jpg

I know that it's not a standard burst, it's just that even when the extreme speed burst was done on the West (G11), it was in a 3 round burst. The 2 round thing is really alien and it kind of bothers me tbh. The mysteries of the eastern bloc I suppose.

Also, what I meant was not the P90 design itself but the magazine which like the G11, lays horizontally across the top of the weapon and remains simple enough that it is easy to load up and doesn't have any weirdness associated with it like the helical tube mag that the PP-19 uses. The problem is the feeding mechanism. Neither the G11 or P90 have good ones. They might be clever but they're not good for rough field usage. If they can iron that problem out, then horizontal toploading is the future. If they can't, then it'll remain the rock paper scissors system we have now I suppose.

But there was another guy - another example in this competition, which did much more traditional take on problem "more accuracy for AK in automatic mode".

АЕК-971/972/973 - is Assault rifle, that share many parts with standart AK-74, made by guys in factory/construction berau in name of Degtyaryov, who was famous firearms manufacture guy, I bet you all know him and his guns. I think, this did most logical and most simple approach without any kind of space magic - to say ultra short, it had "balanced automation". In long, I too lazy to translate this, sorry:

>В узел автоматики добавлен балансир, соответствующий по массе затворной группе. Затворная рама и балансир связаны через зубчатые рейки и шестерню, ось которой укреплена в ствольной коробке. Поршни рамы и балансира играют роль передней и задней стенок газовой камеры. В момент выстрела под давлением пороховых газов они начинают одновременно двигаться в противоположных направлениях с равными скоростями, и импульсы их движения компенсируют друг друга. В результате смещение оружия, вызванное работой автоматики, получается минимальным. Кучность стрельбы очередями из неустойчивых положений заметно улучшается, превосходя аналогичную у АК74М в 1,5-2 раза.

But basicly with full-auto it move not that crazy as AK tend to be. More than that, it more comfy in full auto than АН-94, exept that memetic 2nd bullet that fire super fast, and I guess for soldiers and even for special forces this is more usefull. It was not adopted by Abakan probgram, but it was produced in small numbers from 1990 to 2006 for special forces. There a couple of variants, like 963 using 7,62 ammo for example, and 972 if I not mistaken, NATO ammo.

Ironicly, with recent news and testings for new equipment for soldiers and special forces program, was said, while АК-12/15 will be standart rifles for soldiers, spcial forces will use А-565/А-762 (pic 3 and pic 4) which is updated version of АЕК-971/973, and АН-94 was not metioned, so in the end, АЕК won this 50 years old competition, looks like (if pootine and firends not stealed all monies for this program)

>>13282
>The 2 round thing is really alien and it kind of bothers me tbh. The mysteries of the eastern bloc I suppose.
I think, this is just Stechkin idea of feeding system that also was taked by Nikonov. One round in chamber, second round in transitional place. Third round with this system can't make it speedy enough, so only 2, sorry. Unles you will make 3 barrel AN-94 with 3 underbarrel greneda launchers and all this with silinced barres that shoot СП-5 rounds :--DDDDD

>helical tube mag that the PP-19 uses
Шнековый магазин as we call it, actually interesting things that have it's disadvantages (too much time to load this thing, from top of my head, and in some cases complex details in them) in my opinion is far better thing at this time that what G11-P90 use, because personally I don't have even theoretical system how easely you can feed automatic weapon which also will be very simple and relible.
This type of magazines has no this really big disadvantages, and have a lot real advantages to them of be really compact. This isn't thing which I can see will be used for really mass main battle rifle weapons, but for submachine guns, special and compact variants and all this kinds of things where compact thing with many many bullets is important - they are way to go.

For example Evans rifle in late XIX centuary have like.. 32 or 38 rounds, I don't remember, but anyway, for it's time any of this numbers was really huge. And it was 100% better than using tube magazines for rifles like some experemented with same time

There was development on this side in USSR in WW2, but real comeback it did only recently in really compact submachine guns. Calico ones in USA, ПП90М1 and famous because some videogames his competor ПП-19 Bison both very specilised and limited because USSR dropped massive sumbachine guns during WW2 researches and then on practice like AK wasn't meant to repalce rifles, it was created at first and all this program to replace submachine guns, this why for some time AK and SKS existed same time I want also note this interesting North Korea things - helical tube mags for standart AK feeding :----DDDDDD

https://www.washingtonpost.com/world/asia_pacific/ap-exclusive-first-gene-edited-babies-claimed-in-china/2018/11/25/bb9b74de-f124-11e8-99c2-cfca6fcf610c_story.html?utm_term=.ec21553b6c7e

HONG KONG — A Chinese researcher claims that he helped make the world’s first genetically edited babies — twin girls whose DNA he said he altered with a powerful new tool capable of rewriting the very blueprint of life.

If true, it would be a profound leap of science and ethics.

A U.S. scientist said he took part in the work in China, but this kind of gene editing is banned in the United States because the DNA changes can pass to future generations and it risks harming other genes.

Many mainstream scientists think it’s too unsafe to try, and some denounced the Chinese report as human experimentation.

The researcher, He Jiankui of Shenzhen, said he altered embryos for seven couples during fertility treatments, with one pregnancy resulting thus far. He said his goal was not to cure or prevent an inherited disease, but to try to bestow a trait that few people naturally have — an ability to resist possible future infection with HIV, the AIDS virus.

“It’s almost like not editing at all” if only some of certain cells were altered, because HIV infection can still occur, Church said.

Church and Musunuru questioned the decision to allow one of the embryos to be used in a pregnancy attempt, because the Chinese researchers said they knew in advance that both copies of the intended gene had not been altered.

“In that child, there really was almost nothing to be gained in terms of protection against HIV and yet you’re exposing that child to all the unknown safety risks,” Musunuru said.

The use of that embryo suggests that the researchers’ ”main emphasis was on testing editing rather than avoiding this disease,” Church said.

Even if editing worked perfectly, people without normal CCR5 genes face higher risks of getting certain other viruses, such as West Nile, and of dying from the flu. Since there are many ways to prevent HIV infection and it’s very treatable if it occurs, those other medical risks are a concern, Musunuru said.

TLDR:
>CCR5 Δ32 can be beneficial to the host in some infections (e.g., HIV-1, possibly smallpox), but detrimental in others (e.g., tick-borne encephalitis, West Nile virus). Whether CCR5 function is helpful or harmful in the context of a given infection depends on a complex interplay between the immune system and the pathogen

A bit from Chesterton's A Drift from Domesticity, slightly altered, could apply here.
>But the truth is that nobody has any business to destroy a social institution gene until he has really seen it as an historical institution understood the effect of its absence. If he knows how it arose, and what purposes it was supposed to serve, he may really be able to say that they were bad purposes, or that they have since become bad purposes, or that they are purposes which are no longer served. But if he simply stares at the thing as a senseless monstrosity that has somehow sprung up in his path, it is he and not the traditionalist ethicist who is suffering from an illusion.
Once we know what purpose a gene serves and how the body functions when it is removed ,this kind of thing this might be a good idea. In this case it seems the scientist was interested in being first.

If it works the gene editing method is simply helping to spread a known mutation to pass on its understood benefits. Buried in the wiki there is evidence CCR5 negation can inhibit more than HIV, but some cancers as well. I think the controversy is over this scientist (named He, which is confusing when attributing quotes)jumping the gun and getting out ahead of the science which likelyalmost certainly hasn't fully weighed the cost. In the end it's  just a matter of time before gene editing is understood well enough to get the go ahead from ethicists, and then the governments can fight with churches over the inevitable.

As more data are collected and researchers produce better models for polygenic scores, eventually we'll be able to spot genius embryos by just sequencing them.

Current goverment leader of roskosomos epic-level retard and ultra thief even by pootine russia standarts. I can't imagine roskosmos will exist untill 2020. Tbh pootine goverment screaming about cool moon bases since begining of it's existence and always this programs silently closed before any first results.

Is Putin good for anything at all besides stealing? I cant think of anything successful he even did in last ten years. Even having people killed or invaded lately has been failures so I am guessing this cant be fixed by reinvading Kazakhstan to have Kazakhs use the old launch sites again will do anything. Last I heard the mysterious hole in ISS was thought probably due to some idiot who drilled a hole where it shouldn't be an tried some half assed patch job and it immediately made me think "must have been parts from Putins Russia"

Well this is a sad thing to hear. I was momentarily excited by this news and then remembered while posting "oh...this is the thief king saying something will happen isnt it" Do you think there's at least a possibility of something happening?

Why would they need to invade? They already control Baıqońyr and I'm pretty sure they even still have Saryshaǵan. The only way that control of those get iffy is if they start doing anything nuclear at their sites because the Kazakhs are pretty firmly anti-nuclear due to lingering memory of the people around Semeı getting arsefucked hard and dry by the Soviet tests there.

No and never was.

This Space domes rented or owned by russia still, but they old and outdated.

This was foggy story

Apparently they've figured out how to hook up electrodes to plants in a way that measures whether a plant needs light or not

Title is of course misleading though. It's more a more sophisticated automatic feeder.

Oh this guy started to make english versions of his videos, so I now can share them. They are pretty nice.

I didn't know Russia had its own supersonic passenger jet at least for a little while. Economic factors are what eventually grounded the Concorde, too. I guess we just don't get to go fast.

On russian he have also videos about Boeing-2707 that was canceled, about why we now flying slower even that pre-sonic jets of this era and when we possibly can fly faster. I also did posts about all this shits a little bit up in this thread

Good posts. From what I'm reading about the return of Supersonic transports, the noise is still a big problem. The FAA currently regulates supersonic flights based on speed, rather than decibels:
>The FAA’s existing restrictions can be found at 14 CFR Part 91.817. In essence, that regulation prohibits anyone from operating a civil aircraft at a true flight Mach number greater than 1 over land in the United States and from a certain distance off shore where a boom could reach U.S. shores.
https://www.faa.gov/news/fact_sheets/news_story.cfm?newsId=22754
That made sense once, but doesn't anymore and will likely be changed. NASA is actually working with Lockheed Martin on new seemless body/wing designs that would lower the boom decible level to something no louder than a car door slamming (75 Pdbl). Of course these new models are going to be, as you said, smaller corporate jets for the rich instead of widebodied passenger jets like the Boeing 2707 was supposed to be.

People underestimate how much maintenance goes into a supersonic-capable jet engine. A modern single-engine supersonic fighter hovers around 20-24 hours of maintenance hours per sortie with urgent need for airframes usually limiting them to two or three sorties at best before they're dragged into the shed and looked at thoroughly. Let's cut 4 or 5 off of it for weapons checks and sensors, but add another 10-15 or so for the fact that you're looking at multiple engines on an airliner-sized aircraft, plus more checks for stress damage that happens with supersonic aircraft since it's a lot bigger. The turnaound on these things just isn't fast enough for a mainline passenger jet for multiple reasons, economy being just one. The other is turnaround. A lot of busier airports have a window of error that is below 5 minutes. They need aircraft in and out because the volume of traffic is so high and space is so limited. Now they also have to deal with longer downtimes on significantly higher risk of failure aircraft which throws a spanner into the entire network. The other option is to go with scramjets but I wouldn't envy the one having to design something that can get a scramjet, initial propulsion to ~M4-5, fuel for both and a decent payload of passengers and cargo in their air.

Shit's a pipe dream. With internet communications the way they are, the biggest market for express international travel like that, big boy corporate types needing to jetset to meetings just doesn't need to spend the money when they can have a face to face teleconference in 4k real time.

Speaking of but not really related, this game does do an awesome job of perspective and showing what American cities look like at night when you're flying over them https://www.youtube.com/watch?v=PGQ3-sdHi0o
I'd imagine landing is really difficult, but man I love flying at night. Is there any footage from a supersonic jet how it looks going over cities?
