Submission + - Scientists Finally Turn Hydrogen Into a Metal, Ending a 80-Year Quest (arstechnica.com)

An anonymous reader writes: In 1935, scientists predicted that the simplest element, hydrogen, could also become metallic under pressure, and they calculated that it would take 25 GigaPascals to force this transition (each Gigapascal is about 10,000 atmospheres of pressure). That estimate, in the words of the people who have finally made metallic hydrogen, "was way off." It took until last year for us to reach pressures where the normal form of hydrogen started breaking down into individual atoms—at 380 GigaPascals. Now, a pair of Harvard researchers has upped the pressure quite a bit more, and they have finally made hydrogen into a metal. All of these high-pressure studies rely on what are called diamond anvils. This hardware places small samples between two diamonds, which are hard enough to stand up to extreme pressure. As the diamonds are forced together, the pressure keeps going up. Current calculations suggested that metallic hydrogen might require just a slight boost in pressure from the earlier work, at pressures as low as 400 GigaPascals. But the researchers behind the new work, Ranga Dias and Isaac Silvera, discovered it needed quite a bit more than that. In making that discovery, they also came to a separate realization: normal diamonds weren't up to the task. "Diamond failure," they note, "is the principal limitation for achieving the required pressures to observe SMH," where SMH means "solid metallic hydrogen" rather than "shaking my head." The team came up with some ideas about what might be causing the diamonds to fail and corrected them. One possibility was surface defects, so they etched all diamonds down by five microns to eliminate these. Another problem may be that hydrogen under pressure could be forced into the diamond itself, weakening it. So they cooled the hydrogen to slow diffusion and added material to the anvil that absorbed free hydrogen. Shining lasers through the diamond seemed to trigger failures, so they switched to other sources of light to probe the sample. After loading the sample and cranking up the pressure (literally—they turned a handcrank), they witnessed hydrogen's breakdown at high pressure, which converted it from a clear sample to a black substance, as had been described previously. But then, somewhere between 465 and 495 GigaPascals, the sample turned reflective, a key feature of metals

Submission + - Slashdot Editor David Tries to cover up Fake News Error (slashdot.org)

An anonymous reader writes: Today Slashdot Editor David decided that instead of posting a new article explaining the erroneous Washington Post report that he also submitted here yeserday, he decided to just change the headline and hope nobody would notice. This might have been OK if he'd at least attempted to acknowledge that he made an error, but instead tries to make it look like it was correct all along. Very pathetic, do you agree?

Submission + - Someone in North Korea is Hosting a Facebook Clone

Jason Koebler writes: Someone in North Korea appears to have created a Facebook clone, according to an internet analytics company that traced the site’s DNS to the notoriously isolated country. The social network is an off-the-shelf Facebook clone called dolphinPHP.
Dyn Analytics researcher Doug Madory said that “very few websites resolve to the North Korean address space, and this one does.”

An anonymous reader writes: Users are vulnerable just by reading or previewing an email

Just by looking at an email message in Outlook, attackers can now take control over your PC. The good news is that Microsoft has patched the issue, but unless you updated Outlook after December 8, you're still vulnerable to this issue.

Submission + - ISRO launches six Singaporean satellites

vasanth writes: The Indian Space Research Organisation (ISRO) successfully launched six Singapore satellites on Wednesday, the Indian space agency also tested the fourth stage of its PSLV rocket, the PSLV rocket is a four stage/engine rocket powered by solid and liquid fuel alternatively.

The test to restart the fourth stage of the PSLV rocket would help India in its future launches while attempting to launch multiple satellites in different orbits. Restarting a rocket engine soon after it is shut off is a critical technology that has to be mastered. Once a rocket engine is activated, then the heat generated is very high. The trick is to cool it down in the space and to restart it at a short gap.

With the latest, India has launched a total of 57 foreign satellites for 20 countries, the Wednesday’s launch earned India 26 million euros.

TeLEOS-1 the primary satellite is the first Singapore commercial earth observation satellite. It was launched into a low Earth orbit for "remote sensing" applications. The satellites will orbit around the equator and gather data that will benefit those in the equatorial region. The satellites was put into a 550 kms circular orbit inclined at 15 degrees to the equator.

The next three satellite launches using the Indian PSLV rocket would be navigation satellites, they would be followed by some multiple satellite launches for other countries.

Comment How long is Permenant? (Score 1) 80

It seems that we hear the words 'permanently' when used to reference a digital service, everyone has had the wool pulled over their eyes. Permanently purchase Flappybird? i guarantee you you won't be able to play that in 10 years. Permanently view the video from BBC? lets say i 'buy' (license?) a copy today. Does anyone actually believe that in 2037 i'll be able to view that content, or have some sort of recourse to get either an updated version without extra money, or simply a refund since i'm no longer able to use. Its like you bought 'the product' but like Cinderella, it expired.

Submission + - Dark matter found in Milky Way's core (sciencemag.org)

sciencehabit writes: A team of researchers that the measured speeds and calculated speeds of stars near the center of our galaxy don't agree. This suggests that there is dark matter in the Milky Way's core that is affecting the motion of these suns. The researchers hope their studies will help narrow down searches for the nature of dark matter as well as aid the understanding of galaxy formation.

Submission + - Court releases DOJ memo justifying drone strike on US citizen

An anonymous reader writes: The U.S. Court of Appeals for the Second Circuit on Monday released a secret 2010 Justice Department memo justifying the killing of Anwar al-Awlaki, a U.S citizen killed in a drone strike in 2011. The court released the document as part of a Freedom of Information Act lawsuit filed by The New York Times and the American Civil Liberties Union to make the document public. Then-acting Assistant Attorney General David Barron, in the partially redacted 41-page memo, outlines the justification of the drone strike in Yemen to take out al-Awlaki, an alleged operational leader of al Qaeda.
