New Type of Star Can Emerge From Inside Black Holes, Say Cosmologists 193

Posted by Soulskill from the cross-black-holes-off-your-list-of-good-hiding-places dept.
KentuckyFC writes "Black holes form when a large star runs out of fuel and collapses under its own weight. Since there is no known force that can stop this collapse, astrophysicists have always assumed that it forms a singularity, a region of space that is infinitely dense. Now cosmologists think quantum gravity might prevent this complete collapse after all. They say that the same force that stops an electron spiraling into a nucleus might also cause the collapsing star to 'bounce' at scales of around 10^-14cm. They're calling this new state a 'Planck star' and say its lifetime would match that of the black hole itself as it evaporates. That raises the possibility that the shrinking event horizon would eventually meet the expanding Planck star, which emerges with a sudden blast of gamma rays. That radiation would allow any information trapped in the black hole to escape, solving the infamous information paradox. If they're right, these gamma rays may already have been detected by space-based telescopes meaning that the evidence is already there for any enterprising astronomer to tease apart."

New Zealand Spy Agency Deleted Evidence About Its Illegal Spying On Kim Dotcom 222

Posted by samzenpus from the was-that-wrong? dept.
An anonymous reader writes "The latest news in this: GCSB appears to have deleted key evidence in the case in a ham-fisted attempt to cover up its illegal activities. Even more ridiculous, GCSB is trying to cover this up by claiming that the material had 'aged off' — implying that it was deleted automatically. New Zealand Prime Minister John Key claims that they had to delete the information under the law. Of course, there are a few problems with that. The first is that under New Zealand law, like most countries these days, parties have an obligation to preserve documents likely to be necessary in a legal case. But, even more damning is that there's video of John Key in the New Zealand Parliament trying to defend against an earlier claim that GCSB had deleted some evidence by insisting that GCSB does not delete anything ever:"

Build an Open-Source Electric Car In About One Hour 188

Posted by samzenpus from the new-wheels dept.
First time accepted submitter joe5 writes "Like what Elon Musk has done and want to go all Etsy and build your own electric car? That's apparently now possible now thanks to the OSVehicle Tabby — dubbed the first "Open source vehicle" (memo: it may be cool, but it ain't the first). The OSV guys are taking pre-orders for the Tabby starter kit, with both the two-seater or four-seater configurations going for €500. Then you click to add options. (Note: seats is an "option" so that's the level of luxury you are dealing with here.) When the transaction's complete, OSV sends the parts to your home and you can download the plans and start building. Since the Tabby is open source, OSVehicle will also look to a community of owners and tinkerers for suggestions and recommendations."

HTML5 App For Panasonic TVs Rejected - JQuery Is a "Hack" 573

Posted by samzenpus from the lets-try-this-again dept.
An anonymous reader writes "I have been working on an HTML5 app for Panasonic VIERA TVs, specifically a client for the Plex Media Server. After paying $129 for the developer program, version 1.0 was submitted for inclusion in their VIERA Connect marketplace several weeks ago. After a few requested tweaks, they inquired about how the client communicated with the Plex Server. As many/most web developers do, I used jQuery and its $.ajax call (which is just a wrapper for XMLHttpRequest()). They insisted this was not standard Javascript, and after several communications with them, they replied back with "A workaround like this is considered a hack.". I'm stunned that anyone familiar with HTML would consider jQuery a hack. I've been patient in attempting to explain how jQuery works, but I am getting nowhere. Any thoughts on how I can better explain jQuery to an app reviewer? Yes, I know I can write my app without any Javascript library, but I am really hoping avoid that."

Designer Seeds Thought To Be Latest Target By Chinese 164

Posted by samzenpus from the nice-seeds dept.
An anonymous reader writes "Economic espionage is nothing new but one of the biggest areas being targeted now is agriculture. Here's a story about a FBI investigation to track down theft of seeds from research farms. 'The case of the missing corn seeds first broke in May 2011 when a manager at a DuPont research farm in east-central Iowa noticed a man on his knees, digging up the field. When confronted, the man, Mo Hailong, who was with his colleague Wang Lei, appeared flushed. Mr. Mo told the manager that he worked for the University of Iowa and was traveling to a conference nearby. When the manager paused to answered his cellphone, the two men sped off in a car, racing through a ditch to get away, federal authorities said.'"

Lawmakers Threaten Legal Basis of NSA Surveillance 206

Posted by Soulskill from the please-don't-be-grandstanding dept.
Nerval's Lobster writes "The author of the Patriot Act has warned that the legal justification for the NSA's wholesale domestic surveillance program will disappear next summer if the White House doesn't restrict the way the NSA uses its power. Section 215 of the Patriot Act will expire during the summer of 2015 and will not be renewed unless the White House changes the shocking scale of the surveillance programs for which the National Security Administration uses the authorization, according to James Sensenbrenner Jr. (R-Wis.), an original author of the Patriot Act and its two reauthorizations, stated Washington insider-news source The Hill. 'Unless Section 215 gets fixed, you, Mr. Cole, and the intelligence community will get absolutely nothing, because I am confident there are not the votes in this Congress to reauthorize it,' Sensenbrenner warned Deputy Attorney General James Cole during the Feb. 4 hearing. Provisions of Section 215, which allows the NSA to collect metadata about phone calls made within the U.S., give the government a 'very useful tool' to track connections among Americans that might be relevant to counterterrorism investigations, Cole told the House Judiciary Committee. The scale of the surveillance and lengths to which the NSA has pushed its limits was a "shock" according to Sensenbrenner, who also wrote the USA Freedom Act, a bill to restrict the scope of both Section 215 and the NSA programs, which has attracted 130 co-sponsors. Senate Judiciary Committee Chairman Patrick Leahy (D-Vt.) has sponsored a similar bill in the Senate."

Utah Bill Would Prevent Regional Fiber Networks From Growing 111

symbolset writes "On the heels of the smackdown received by cable lobbyists in Kansas, Ars reports out of Utah that the cable companies aren't giving up hopes of preventing competition through legislation. The bill, called Interlocal Entity Service Prohibition, would prevent a regional fiber consortium from building infrastructure outside the boundaries of its member cities and towns — a direct attack on Google's work in Provo and the UTOPIA network. Utah is the third state to be involved in the Google Fiber rollout of gigabit fiber to the home."

Amputee Has Prosthetic Hand Wired To Nerves 72

Posted by Soulskill from the thumbs-up dept.
New submitter kalman5 writes "Dennis Aabo Sørensen is the first amputee in the world to feel sensory rich information — in real-time — with a prosthetic hand wired to nerves in his upper arm. Sørensen could grasp objects intuitively and identify what he was touching while blindfolded. The surgical team 'attached electrodes from a robotic hand to a 36-year-old volunteer's median and ulnar nerves. Those nerves carry sensations that correspond with the volunteer's index finger and thumb, and with his pinky finger and the edge of his hand, respectively. The volunteer controlled the prosthetic with small muscle movements detected by sEMG, a method that dates to the 1970s and measures electrical signals through the skin—unlike the electrodes attached to his nerves, sEMG is not invasive.' The results? 'The volunteer was able to complete the requested tasks with his prosthetic thumb and index finger 67 percent of the time the first day and 93 percent of the time by the seventh day of the experiment, Micera and colleagues report. He found the pinky finger harder to control: he was only able to accomplish the requested grip 83 percent of the time by the end of the experiment.'"

Ship Anchor, Not Sabotaging Divers, Possibly Responsible For Outage 43

Posted by samzenpus from the who's-to-blame dept.
Nerval's Lobster writes "This week, Egypt caught three men in the process of severing an undersea fiber-optic cable. But Telecom Egypt executive manager Mohammed el-Nawawi told the private TV network CBC that the reason for the region's slowdowns was not the alleged saboteurs — it was damage previously caused by a ship. On March 22, cable provider Seacom reported a cut in its Mediterranean cable connecting Southern and Eastern Africa, the Middle East and Asia to Europe; it later suggested that the most likely cause of the incident was a ship anchor, and that traffic was being routed around the cut, through other providers. But repairs to the cable took longer than expected, with the Seacom CEO announcing March 23 that the physical capability to connect additional capacity to services in Europe was "neither adequate nor stable enough," and that it was competing with other providers. The repairs continued through March 27, after faults were found on the restoration system; that same day, Seacom denied that the outage could have been the work of the Egyptian divers, but said that the true cause won't be known for weeks. 'We think it is unlikely that the damage to our system was caused by sabotage,' the CEO wrote in a statement. 'The reasons for this are the specific location, distance from shore, much greater depth, the presence of a large anchored vessel on the fault site which appears to be the cause of the damage and other characteristics of the event.'"
