Hubble Discovers a Fast-Aging Star Nicknamed "Nasty 1" 1

Posted by samzenpus
from the vanity-plate-ideas dept.
An anonymous reader writes: Using NASA's Hubble Space Telescope, Astronomers have uncovered surprising new clues about a large, rapidly aging star whose behavior has never been seen before. The star is so strange in fact that astronomers have nicknamed it "Nasty 1," a play on its catalog name of NaSt1. Wolf-Rayet stars like NaSt1 are typically large, rapidly evolving stellar bodies that form by shedding their hydrogen-filled outer layers quickly, exposing a bright hot, helium-burning core. Nasty 1 is unique because it contains a disk like structure. "We were excited to see this disk-like structure because it may be evidence for a Wolf-Rayet star forming from a binary interaction," said Jon Mauerhan of UC Berkeley, lead author on the new Nasty 1 paper. "There are very few examples in the galaxy of this process in action because this phase is short-lived, perhaps lasting only a hundred thousand years, while the timescale over which a resulting disk is visible could be only ten thousand years or less."

Machine That "Uncooks Eggs" Used To Improve Cancer Treatment 14

from the closer-to-a-cure dept.
hypnosec writes: An Australian invention that gained attention for being able to "unboil" an egg has now been put to use in the treatment of cancer. The device has boosted the potency of a common cancer treatment drug, carboplatino, as much as four-and-a-half-times. ABC.net reports: "Flinders Centre for Innovation in Cancer director Professor Ross McKinnon said it meant a huge advance for cancer treatment. 'It gives us the promise of offering an alternative where we have more drug being delivered to the tumour and less drug being delivered to the rest of the body,' he said. 'That means less side-effects for the patient and hopefully a much better effect in terms of tumour response. What this group are doing is an example of one drug but we would hope we could extend this to many drugs.' The device can process proteins more efficiently than current methods, with possible big ramifications for the pharmaceuticals industry.

DaveS7 writes: There's been no shortage of high profile people weighing in on the subject of AI lately. We've heard warnings from Elon Musk, Bill Gates, and Stephen Hawking while Woz seems to have a more ambivalent opinion on the subject. The Epoch Times has compiled a list of academics in the field of AI research who are offering their own opinions. From the article: "A 2014 survey conducted by Vincent Müller and Nick Bostrom of 170 of the leading experts in the field found that a full 18 percent believe that if a machine super-intelligence did emerge, it would unleash an 'existential catastrophe' on humanity. A further 13 percent said that advanced AI would be a net negative for humans, and only a slight majority said it would be a net positive."

An anonymous reader writes: The Russian space program has experienced numerous accidents and delays recently, leading Indian officials to call into question its long term viability. Now India has decided to pull out of a partnership with Russia for a mission to the moon. According to the Examiner: "Previously, India was scheduled to launch a Russian lander on one of its rockets and send it to the lunar South Pole. Now, according to a story in Russia and India Report, India will go it alone, building its own lander to touch down on the lunar surface within the next few years.

Dell Precision M3800 Mobile Workstation Packs Thunderbolt 2, Quadro, IGZO2 Panel 87

Posted by samzenpus
from the running-the-numbers dept.
MojoKid writes: Dell recently revamped their M3800 model to better entice graphic designers, engineers, and other high-end users who often work in the field, with a true mobile workstation that's both sufficiently equipped to handle professional grade workloads and is thin and light to boot. Dell claims the M3800 is the "world's thinnest and lightest 15-inch mobile workstation" and at 4.15 pounds, it could very well be. In addition, ISV tools certifications matter for workstation types, so the M3800 gets its pixel pushing muscle from an NVIDIA Quadro K1100M GPU with 2GB of GDDR5 memory. Other notable specs include an Intel Core i7-4712HQ quad-core processor, 16GB of DDR3L memory, and a 256GB mSATA SSD. One of the new additions to the M3800 is a Thunderbolt 2 port with transfer speeds of up to 20Gbps that allows for the simultaneous viewing/editing and backing up of raw 4K video. Finally, the M3800 is equipped with a 3840x2160 native resolution IGZO2 display, which equates to a 60 percent increase in pixel density over a current gen MacBook Pro with Retina display. Performance-wise, the M3800 holds up pretty strong with standard productivity workloads, though as you can image it excels more-so in graphics rendering throughput.

Al-Qaeda's Job Application Form Revealed 113

HughPickens.com writes: ABC News reports that the Office of the Director of National Intelligence has released a list of English-language material recovered during the raid the killed Osama bin Laden in Abbottabad, Pakistan in 2011 including one document dubbed "Instructions to Applicants," that would not be entirely out of place for an entry-level position at any American company – except for questions like the one about the applicant's willingness to blow themselves up. The questionnaire includes basic personal details, family history, marital status, and education level. It asks that applicants "answer the required information accurately and truthfully" and, "Please write clearly and legibly." Questions include: Is the applicant expert in chemistry, communications or any other field? Do they have a family member in the government who would cooperate with al Qaeda? Have they received any military training? Finally, it asks what the would-be jihadist would like to accomplish and, "Do you wish to execute a suicide operation?" For the final question, the application asks would-be killers that if they were to become martyrs, who should al Qaeda contact?

The corporate tone of the application is jarringly amusing, writes Amanda Taub, but it also hints at a larger truth: a terrorist organization like al-Qaeda is a large bureaucratic organization, albeit one in the "business" of mass-murdering innocent people. Jon Sopel, the North American editor from BBC News, joked that the application "looks like it has been written by someone who has spent too long working for Deloitte or Accenture, but bureaucracy exists in every walk of life – so why not on the path to violent jihad?"

Google and Gates-Backed Khan Academy Introduces "Grit"-Based Classroom Funding 80

theodp writes: Their intentions are no doubt good, but some will be troubled by Google and Khan Academy's recently-concluded LearnStorm initiative, which pitted kids-against-kids, schools-against-schools, and cities-against-cities in a 3-month learning challenge for prizes based not only on students' mastery of math skills on Khan Academy, but also their perceived 'hustle' (aka 'grit'). "Points are earned by mastering math skills and also for taking on challenging new concepts and persevering," explained a Khan Academy FAQ. A blog entry further explained, "They've earned points and prizes not only for mastering math skills but also for showing 'hustle,' a metric we created to measure grit, perseverance, and growth. They competed over 200,000 hours of learning and 13.6 million standards-aligned math problems. In addition, thanks to the generosity of Google.org, DonorsChoose.org, and Comcast's Internet Essentials, 34 underserved schools unlocked new devices for their classrooms and free home internet service for eligible families, increasing student access to online learning tools like Khan Academy." Apparently funded by a $2 million Google grant, the Google, Khan Academy, and DonorsChoose grit-based classroom funding comes on the heels of the same organizations' gender-based classroom funding initiative. Supported by some of the world's wealthiest individuals and corporations, Khan Academy's Board members include a Google Board member (Diane Green), spouse of a Google Board member (Ann Doerr), and the Managing Partner of Bill Gates' bgC3 (Larry Cohen); former Board members include Google Executive Chairman Eric Schmidt.

A Beautiful Mind Mathematician John F. Nash Jr. Dies 121

Posted by samzenpus
from the rest-in-peace dept.
Rick Zeman writes: John F. Nash Jr. revolutionized the mathematical field of game theory and was given a mind that was unique and deeply troubled. He became known to most people by the movie about his life, A Beautiful Mind. Dr. Nash died, along with his wife, May 24 in a two-car accident on the New Jersey Turnpike. The Washington Post reports: "In 1994, when Dr. Nash received the Nobel Prize in economics, the award marked not only an intellectual triumph but also a personal one. More than four decades earlier, as a Princeton University graduate student, he had produced a 27-page thesis on game theory — in essence, the applied mathematical study of decision-making in situations of conflict — that would become one of the most celebrated works in the field. Before the academic world could fully recognize his achievement, Dr. Nash descended into a condition eventually diagnosed as schizophrenia. For the better part of 20 years, his once supremely rational mind was beset by delusions and hallucinations. By the time Dr. Nash emerged from his disturbed state, his ideas had influenced economics, foreign affairs, politics, biology — virtually every sphere of life fueled by competition. But he been absent from professional life for so long that some scholars assumed he was dead."

Soft Sensors Map Skin Mechanics 8

Posted by samzenpus
from the put-on-your-sensors dept.
MTorrice writes: An international research team has built electronic, flexible patches that can measure the mechanical properties of skin and other biological tissue. The sensors consist of nanoribbons of a piezoelectric material, lead zirconate titanate, which deforms when jolted with electrical energy and, conversely, produces electricity when it's deformed. The researchers mapped the skin elasticity of dozens of patients in the clinic, building up quantitative data on healthy and damaged tissue. The information could help doctors better assess conditions such as dermatitis and skin cancer. The team believes that similar sensors could be implanted inside the body to monitor blood vessels and other soft tissue for damage or dysfunction.

How Java Changed Programming Forever 377

from the changing-the-game dept.
snydeq writes: With Java hitting its 20th anniversary this week, Elliotte Rusty Harold discusses how the language changed the art and business of programming, turning on a generation of coders. Infoworld reports: "Java's core strength was that it was built to be a practical tool for getting work done. It popularized good ideas from earlier languages by repackaging them in a format that was familiar to the average C coder, though (unlike C++ and Objective-C) Java was not a strict superset of C. Indeed it was precisely this willingness to not only add but also remove features that made Java so much simpler and easier to learn than other object-oriented C descendants."

Bismillah writes: Ross Anderson and Laurent Simon of Cambridge University studied a range of Android devices and found that even though a "factory reset" is supposed to fully wipe storage, it often doesn't. Interestingly enough, full-device encryption could be compromised by the incomplete wiping too. ITnews reports: "The researchers estimated that 500 million Android devices may not fully wipe device disk partitions. As many as 630 million phones may not wipe internal SD cards. Five 'critical failures' were outlined in the researchers' Security Analysis of Android Factory Resets paper.

Advocatus Diaboli writes: A newly released top secret document reveals that the NSA planned to hijack Google and Samsung app stores to plant spying software on smartphones. The report on the surveillance project, dubbed "IRRITANT HORN," shows the U.S. and its "Five Eyes" alliance: Canada, the United Kingdom, New Zealand and Australia, were looking at ways to hack smartphones and spy on users. According to The Intercept: "The top-secret document, obtained from NSA whistleblower Edward Snowden, was published Wednesday by CBC News in collaboration with The Intercept. The document outlines a series of tactics that the NSA and its counterparts in the Five Eyes were working on during workshops held in Australia and Canada between November 2011 and February 2012."
