NASA tests small nuclear reactor that could power a habitat on Mars

Everyone from Elon Musk to Donald Trump wants to send a manned mission to Mars in the not too distant future, but there are quite a few problems that need to be solved before we can achieve that goal. A major one is the issue of energy. Long-term stays on Mars, or anywhere else for that matter, will require lots of energy, as will the trip back to Earth. However, loading a rocket up with all of the necessary fuel won’t work — we would need too much. So a way to create fuel on the go is a must and researchers at NASA, Los Alamos National Laboratory and the Department of Energy announced today that they’ve conducted successful tests of a system that can do just that. Kilopower is a small nuclear reactor that can generate a reliable power supply. Versions range from 1 kilowatt — enough to power a basic toaster — to ten kilowatts and Kilopower project researchers said in a Space.com article that around four or five of the latter would be needed to power a habitat on Mars . “Kilopower’s compact size and robustness allows us to deliver multiple units on a single lander to the surface that provides tens of kilowatts of power, ” Steve Jurczyk, associate administrator of NASA’s Space Technology Mission Directorate, said during a press conference today. Testing of the Kilopower system has gone smoothly so far and in March, the team plans to conduct a full-power test. To hear more about how Kilopower works, check out the video below. Via: Reuters

Samsung starts producing GDDR6 RAM for next-gen graphics cards

You can start getting pumped about the next generation of graphics cards, as Samsung has announced that it’s building the first-ever 16-gigabit GDDR6 chips using its 10-nanometer class technology. The news isn’t a complete surprise, as Samsung previously said that GDDR6 was coming when it unveiled 8-gigabit DDR4 RAM chips last month and won a CES 2018 Innovation Award in November. “Beginning with this early production of the industry’s first 16Gb GDDR6, we will offer a comprehensive graphics DRAM line-up, with the highest performance and densities, in a very timely manner, ” said Samsung’s Senior VP Jinman Han. The company also did a minor tease, saying the chips “will play a critical role in early launches of next-generation graphics cards and systems.” The voracious demand from bitcoin mining has pushed the GeForce GTX 1070 from a $380 suggested retail price to $890. You may debate whether Samsung is behind TMSC with 7-nanometer tech, or if it’s 10-nanometer tech — now on its second generation — is inferior to what Intel ( still ) has in store for the future. However, at least Samsung’s foundries our stamping out the damn chips, which is all that really matters to consumers. The GDDR6 chips will make things all kinds of better for gamers. First off, they offer double the speed of previous 8-gigabit GDDR5 RAM, with speeds up to 72 GB/s (that’s gigabytes). They also consume about 35 percent less energy, Samsung says, and offer a 30 percent manufacturing productivity gain, so that its assembly lines can build more chips in the same amount of time. What that means to you, in theory, is better gaming performance, less power drain and cheaper graphics cards. That is, unless all the chips are gobbled up by bitcoin miners. The voracious demand from that industry has pushed a GeForce GTX 1070 from a $380 suggested retail price to $890, as Techspot noted. That’s killing gamers and folks who love to build rigs (and promoting pollution ), but all of it is obviously good for Samsung’s profits .

The war over apostrophes in Kazakhstan’s new alphabet

There’s a fascinating linguistic fight brewing in Kazakhstan, due to the president’s decision to adopt a new alphabet for writing their language, Kazakh. The problem? It’s got too many apostrophes! For decades, Kazakhs have used the Cyrillic alphabet, which was imposed on them by the USSR back in the 30s. Now that Kazakhstan has started moving away from Russia — including making Kazakh more central in education and public life — the president decided he wanted to adopt a new alphabet, too. He wanted it based on the Latin one. But! Kazakh has many unique sounds that can’t be easily denoted using a Latin-style alphabet. Kazakhstan’s neighbors solved that problem by following the example of Turkey, where they use umlauts and phonetic symbols. But Kazkhstan’s president didn’t want that — and instead has pushed for the use of tons of apostrophes instead. Kazakhstan’s linguists intellectuals think this is nuts, as the New York Times reports: The Republic of Kazakhstan, for example, will be written in Kazakh as Qazaqstan Respy’bli’kasy. Others complained the use of apostrophes will make it impossible to do Google searches for many Kazakh words or to create hashtags on Twitter. “Nobody knows where he got this terrible idea from,” said Timur Kocaoglu, a professor of international relations and Turkish studies at Michigan State, who visited Kazakhstan last year. “Kazakh intellectuals are all laughing and asking: How can you read anything written like this?” The proposed script, he said, “makes your eyes hurt.” [snip] Under this new system, the Kazakh word for cherry will be written as s’i’i’e, and pronounced she-ee-ye. “When scholars first learned about this, we were all in shock,” Mr. Kazhybek said. What’s particularly interesting are the technological and geopolitical reasons behind the president’s embrace of apostrophes. He claims it’s about making the language easy to type on computers; no need to have a keyboard equipped with umlauts and other special characters. But critics say it’s about something else — the president’s desire to not alienate Russia, which doesn’t like the idea of the various former Soviet satellites adopting Turkic styles … The only reason publicly cited by Mr. Nazarbayev to explain why he did not want Turkish-style phonetic markers is that “there should not be any hooks or superfluous dots that cannot be put straight into a computer,” he said in September. He also complained that using digraphs to transcribe special Kazakh sounds would cause confusion when people try to read English, when the same combination of letters designates entirely different sounds. But others saw another possible motivation: Mr. Nazarbayev may be eager to avoid any suggestion that Kazakhstan is turning its back on Russia and embracing pan-Turkic unity, a bugbear for Russian officials in both czarist and Soviet times. Oh, and a director shot a video parodying the apostrophe-ridden words the president’s new language would produce . The image above is from it. It’s a great story , with fascinating nuance into Kazakhstan’s politics; go read it in full! A very good reminder of how deeply political language is, was, and probably always will be. (There’s a cool video embedded where you can learn Kazakh phrases , too.)

Nile Rodgers shares unreleased, bare bones demo of Bowie’s ‘Let’s Dance’

To celebrate what would have been David Bowie’s 71st birthday, Chic’s Nile Rodgers shared this newly-mixed demo of the 1983 hit single, “Let’s Dance.” Rolling Stone reports : “I’ve been blessed with a wonderful career but my creative partnership with David Bowie ranks very, very, very high on the list of my most important and rewarding collaborations,” Rodgers said in a statement. “This demo gives you, the fans, a bird’s eye view of the very start of it! I woke up on my first morning in Montreux with David peering over me. He had an acoustic guitar in his hands and exclaimed, ‘Nile, darling, I think this is a HIT!'” Bowie was so eager to lay down the track that a makeshift band made up of local musicians was formed specifically for this recording of “Let’s Dance”; the identities of the drummer and second guitarist on the recording are still unknown. (“If you played 2nd guitar or drums let us know who you are,” Rodgers added.) Thirty-five years after recording the demo, Rodgers unearthed and then mixed the track at his Connecticut studio specifically for its digital-only release. The demo concludes with Bowie exclaiming, “That’s it! That’s it! Got it,” as if he knew he had just recorded one of his biggest hits. The demo was recorded at Mountain Studios in Montreux, Switzerland on December 19th and 20th, 1982.

How gold nanoparticles may make killing tumors easier

Enlarge / Nanoparticles (black dots) sit in the remains of a cell they’ve helped kill. (credit: University of Michigan ) One of the ways to kill a cancer is to cook it, since heat can kill cells. The trick, of course, is to only cook the cancer and not the surrounding tissue. To do this, you need to have an accurate idea of the extent of a tumor, a precise mechanism for delivering heat, and a damn good thermometer. It may surprise you to learn that gold nanoparticles do a pretty good job of achieving the first two. The third—a good thermometer—has eluded researchers for quite some time. But, now it seems that gold nanoparticles may provide the full trifecta . Drowning a tumor in molten gold Some cancers—the ones most people imagine when they think of cancer—form lumps of tissue. At some point, these lumps require a blood supply. Once supplied with blood vessels, the tumor can not only grow, but it has a readily available transport system to deliver the cells that can spread the cancer throughout the body. For the patient, this is not good news. The development of a blood supply opens up new imaging and treatment options, though. Cancer tumors are not well-organized tissues compared to healthy tissue like muscle or kidney tissue. So there are lots of nooks and crannies in a tumor that can trap small particles. And this disorganization is exactly what researchers hope to take advantage of. Gold nanoparticles are injected into the blood stream; these exit the blood supply, but, in most of the body, they get rapidly cleaned out. Except that, inside tumors, the nanoparticles lodge all over the place. Read 22 remaining paragraphs | Comments

Meteor lights up southern Michigan

Enlarge / That’s no moon! Early last night local time, a meteor rocketed through the skies of Southern Michigan, giving local residents a dramatic (if brief) light show. it also generated an imperceptible thump, as the UG Geological Survey confirmed that there was a coincident magnitude 2.0 earthquake. The American Meteor Society has collected over 350 eyewitness accounts , which ranged from western Pennsylvania out to Illinois and Wisconsin. They were heavily concentrated over southern Michigan, notably around the Detroit area. A number of people have also posted videos of the fireball online; one of the better compilations is below. A compilation of several videos from Syracuse.com. The American Meteor Society estimates that the rock was relatively slow-moving at a sedate 45,000km an hour. Combined with its production of a large fireball, the researchers conclude it was probably a big rock. NASA’s meteorwatch Facebook page largely agrees and suggests that this probably means that pieces of the rock made it to Earth. If you were on the flight path, you might want to check your yard.
