'Curiosity' Lead Engineer Suggests Printing Humans On Other Planets 323

Posted by timothy from the ok-use-the-wormhole-to-get-the-printer dept.
Jason Koebler (3528235) writes "Adam Steltzner, the lead engineer on the NASA JPL's Curiosity rover mission, believes that to send humans to distant planets, we may need to do one of two things: look for ways to game space-time—traveling through wormholes and whatnot—or rethink the fundamental idea of 'ourselves.' 'Our best bet for space exploration could be printing humans, organically, on another planet,' said Steltzner."

German Scientists Successfully Test Brain-Controlled Flight Simulator 73

Posted by timothy from the you-may-now-turn-on-approved-neural-wetware dept.
New submitter stephendavion (2872091) writes "Scientists from the Institute for Flight System Dynamics at Technical University of Munich (TUM), Germany have demonstrated the feasibility of flying a brain-controlled aircraft. Led by professor Florian Holzapfel, the team is researching ways that brain-controlled flight works in the EU-funded project 'Brainflight'. TUM project head Tim Fricke said a long-term vision of the project is to make flying accessible to more people." So far, the tests are only simulator based, but promising.

Is Bamboo the Next Carbon Fibre? 198

Posted by timothy from the ok-but-avoid-the-spreading-kind dept.
An anonymous reader writes with this excerpt from the BBC about one very cool building material: "Real carbon fibre, mind, is still just as wondrous as it was in the last century, even if a bit more commonplace in road cars. But it's still very expensive to make in large pieces and quantities, it requires copious energy to manufacture, can be very brittle if made poorly, is not recyclable and can impose a detrimental impact of the environment when being produced. In other words, it is ripe for disruption. Technology stands still for no one. But could nature provide carbon fibre's replacement? So argues Gary Young, a renowned manufacturer of surfboards who has spent his life pioneering alternative materials use for that industry. 'With the right approach, bamboo can be used in many applications in the automotive world where its performance qualities can better carbon fibre's,' Young says. 'Plus, it does not have a negative effect on the environment.''"

Should We Eat Invasive Species? 290

Posted by timothy from the will-ponder-this-over-some-nutria-mousse dept.
The Washington Post's Energy & Environment section raises today the question of whether the best way to control certain invasive species is to eat them. The biggest success story on this front in the U.S. has been the lionfish; it destroys the habitat of some other fish in the areas where it's been introduced, but it turns out to be a palatable food fish, too. Its population has gone down since the start of a concerted effort to encourage it as a food, rather than just a nuisance. The article touches on invasive species of fish and crustaceans, but also land animals and plants. I know that garlic mustard (widespread in eastern U.S. forests) is tasty, and so are the blackberries all over Seattle.

Efforts To Turn Elephants Into Woolly Mammoths Are Already Underway 147

Posted by Soulskill from the still-waiting-on-a-mammoth-steak dept.
Jason Koebler writes: "Researchers are working to hybridize existing animals with extinct ones in order to create a '2.0' version of the animal. Using a genome editing technique known as CRISPR, Harvard synthetic biologist George Church has successfully migrated three genes, which gave the woolly mammoth its furry appearance, extra layer of fat, and cold-resistant blood, into the cells of Asian elephants, with the idea of eventually making a hybrid embryo. In theory, given what we know about both the woolly mammoth genome and the Asian elephant genome, the final product will be something that more closely resembles the former than the latter."

Why wasn't the development of such a tool a graduate research project ?

Oh please goddess no. You'll end up with some arcane piece of experimental theology written in a private version of a language no-one has ever heard of, undocumented and unsupportable. Have it written by someone with a suitable track record, a suitable number of decades experience in whatever, and with proven implementations and documentation skills. It will be expensive, but it will cost far less in the long run.

Comment Re:Backups (Score 1) 564

Bad news most likely on this front. I have worked University IT, and I can guarantee they are going to have problems.

For one, no matter how many layers of backups you have, when you are working with a bunch of 90 year old academics, they will always find a way to miss every single one.

And more grievous, Universities tend to have important data that absolutely cannot be backed up in any normal way. Data that is legally obligated to stay on one specific computer in one specific room and never leave; under penalty of legal action.

That level of insanity is why I am laughing. The bold parts specifically. When you allow people who have no clue how a system works to legislate how it works, you get this.

You have no idea what you are talking about. Restrictions like these are usually imposed by the legal IT people in the funding agency that funds the research, and they do very much understand exactly what they are doing (there are plenty of people in these agencies who are clueless, but the legal IT people are usually pretty good). Or suppose the project was doing research for the cops into identifying the makers of child porn; believe me that stuff would be locked down REAL tight.

On Usenet there is the killfile, so at least people who know what they're doing can trash the crap, and these would typically be the kind of people the negatively-rated posters would have been trying to impress. The problem remains that newcomers and those unaware of the 'k' button remain exposed to the idiocies of such posters.

Elsewhere, it's not clear whom the negatively-rated posters are trying to impress — if anyone. More likely they're just trying to get something, anything, out on the interwebs, so that their visibility increases.

The ones I'm most familiar with (from running lists and web forums) are like the loudmouths in bars, with an opinion on everything, and almost all of it wrong; but it's not clear if this is the type of poster the researchers were dealing with.

Momentous Big Bang Findings Questioned 154

Posted by Soulskill from the science-is-self-correcting dept.
sciencehabit writes "The biggest discovery in cosmology in a decade could turn out to be an experimental artifact, according to a report by a physics blogger. The blogger says the BICEP group — the team behind the huge announcement of the moments after the Big Bang a few weeks back — had subtracted the wrong Planck measurement of foreground radiation in deriving its famous evidence for gravitational waves. As a result, the calculation is invalid and the so-called evidence inconclusive. Intriguingly, the BICEP team has yet to flat-out deny this."

Flaws In Popular Solar Power Management Platform Could Crash the Grid 90

Posted by samzenpus from the there-goes-the-sun dept.
mask.of.sanity (1228908) writes "Criminals could potentially cause black-outs and mess with power grid configurations by exploiting flaws in a popular solar panel management system used by thousands of homes and businesses. The threat is substantial because, as the company boasts, its eponymous management system runs globally on roughly 229,300 solar plants that typically pump out 566TWh of electrical energy."

The Strange Death of Comet Ison 49

Posted by Unknown Lamer from the need-better-space-cameras dept.
KentuckyFC (1144503) writes "Last year, astronomers announced that a small ball of ice and rock heading towards the inner Solar System could turn out to be the most eye-catching comet in living memory. They calculated that Comet Ison's orbit would take it behind the Sun but that it would then head towards Earth where it would put on a spectacular display of heavenly fireworks. Sure enough, Ison brightened dramatically as it headed Sunwards. But as astronomers watched on the evening of 28 November, the brightly flaring Ison moved behind the Sun but never emerged. The comet simply disappeared. Now a new analysis of the death of Ison suggests that the comet was doomed long before it reached the Sun. Images from several Sun-observing spacecraft that had a unique view of events, indicate that Ison exhausted its supply of water and other ice in the final flare-ups as it approached the Sun. The new study shows that all that was left in its last hours were a few hundred thousands pebbles glowing brightly as they vaporized in the Sun's heat. In fact, Comet Ison died in full view of the watching hordes of astronomers on Earth who did not realize what they were watching at the time."

A mechanical lock that wears out the tumblers due to age or use is acceptable: you use it, it wears, you replace it after x years.

A lock that randomly decides not to work because of unexpected component failure (read: shoddy quality) is unacceptable. What is also unacceptable is the ludicrous price of electronic lock/key replacement, and the reluctance of manufacturers to provide at least one (preferably) two spare keys with the new car, and their apparent inability to provide replacement keys (on their own) at all.

Cars need to have a mechanical-only standby door lock/key, if only to let you into the shelter of the interior in emergencies, whether or not you can then start the engine. If manufacturers move to keyless operation, it will probably take many deaths before they provide a mechanical fallback.

Elderly Mice Perk Up With Transfused Blood 178

Posted by timothy from the price-of-mouse-blood-skyrockets dept.
Some exciting news, as reported by the Wall Street Journal, might make you glad that human blood is a renewable resource: "Giving old mice blood from young ones makes them smarter and improves such functions as exercise capacity, according to reports from two research teams that point to new ways to study and potentially treat diseases of aging. In one study, researchers at Stanford University and the University of California, San Francisco found that blood transfusions from young mice reversed cognitive effects of aging, improving the old mice's memory and learning ability. The report was published Sunday in the journal Nature Medicine. Two other reports appearing in Science from researchers at Harvard University found that exposing old mice to a protein present at high levels in the blood of young mice and people improved both brain and exercise capability. An earlier report by some of the same researchers linked injections of the protein to reversal of the effects of aging on the heart. ... What isn't known from all this research, said Buck Institute's Dr. [Brian] Kennedy, is whether young blood might also increase the life span of mice and, if so, what such implications for humans might be."
