New Class of "Non-Joulian" Magnets Change Volume In Magnetic Field 1

Posted by Soulskill
from the polarizing-research dept.
Zothecula notes an announcement from the University of Maryland saying they have developed a new class of magnets, called "Non-Joulian" magnets, which physically expand in the presence of a magnetic field. "In the 1840s, physicist James Prescott Joule discovered that iron-based magnetic materials changed their shape but not their volume when placed in a magnetic field. This phenomenon is referred to as "Joule Magnetostriction," and since its discovery 175 years ago, all magnets have been characterized on this basis." Another significant property of these new magnets is that they can harvest or convert energy with very little waste heat (abstract). The magnets are created when thermally-treated, iron-based alloys are heated in a furnace, then rapidly cooled. When they reach room temperature, they have an odd, almost cellular shape on the microscopic level. The researchers say the magnets have numerous applications for energy-efficient sensors and actuators.

An anonymous reader notes this report from Channel 4 News that Adult FriendFinder, one of the largest dating sites in the world, has suffered a database breach that revealed personal information for 3.9 million of its users. The leaked data includes email addresses, IP addresses, birth dates, postal codes, sexual preferences, and information indicating which of them are seeking extramarital affairs. There even seems to be data from accounts that were supposedly deleted. Channel 4 saw evidence that there were plans for a spam campaign against these users, and others are worried that a blackmail campaign will follow. "Where you've got names, dates of birth, ZIP codes, then that provides an opportunity to actually target specific individuals whether they be in government or healthcare for example, so you can profile that person and send more targeted blackmail-type emails," said cybercrime specialist Charlie McMurdy.

ESA Satellite Shows Sudden Ice Loss In Southern Antarctic Peninsula 107

from the uber-for-ice-cubes dept.
ddelmonte tips news that the ESA's CryoSat spacecraft has detected a sharp increase in the rate at which ice is being lost in a previously stable section of Antarctica. In 2009, glaciers at the Southern Antarctic Peninsula began rapidly shedding ice into the ocean, at a rate of roughly 60 cubic kilometers per year (abstract). From the ESA's press release: This makes the region one of the largest contributors to sea-level rise in Antarctica, having added about 300 cubic km of water into the ocean in the past six years. Some glaciers along the coastal expanse are currently lowering by as much as four m each year. Prior to 2009, the 750 km-long Southern Antarctic Peninsula showed no signs of change. ... The ice loss in the region is so large that it has even caused small changes in Earth’s gravity field, detected by NASA’s GRACE mission. Climate models show that the sudden change cannot be explained by changes in snowfall or air temperature. Instead, the team attributes the rapid ice loss to warming oceans.

An anonymous reader writes: Mozilla has announced plans to launch a feature called "Suggested Tiles," which will provide sponsored recommendations to visit certain websites when other websites show up in the user's new tab page. The tiles will begin to show up for beta channel users next week, and the company is asking for feedback. For testing purposes, users will only see Suggested Tiles "promoting Firefox for Android, Firefox Marketplace, and other Mozilla causes." It's not yet known what websites will show up on the tiles when the feature launches later this summer. The company says, "With Suggested Tiles, we want to show the world that it is possible to do relevant advertising and content recommendations while still respecting users’ privacy and giving them control over their data."

India Targets July/August To Test Its Space Shuttle 49

New submitter gubol123 writes with news that India is close to launching its own space shuttle for the first time. Their space program, ISRO, is planning the shuttle's first test flight for some time in July or August. The unmanned shuttle will fly to a height of approximately 70 kilometers before splashing down in the Bay of Bengal. Oddly, the vehicle itself probably won't be recovered. When it lands in the water, it will sink, and there are no plans to try to bring it back to the surface. The most important obstacles are surviving re-entry and simply staying intact during splashdown. Scientists and ISRO engineers are hoping the shuttle program, when finished, will drop the cost of placing objects in orbit by a factor of 10.

How Java Changed Programming Forever 218

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."

Factory Reset On Millions of Android Devices Doesn't Wipe Storage 68

from the stucking-around dept.
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."

DNA On Pizza Crust Leads To Quadruple Murder Suspect 130

HughPickens.com writes: In a case straight out of CSI, CNN reports that police are searching for the man suspected in the gruesome slayings of the Savopoulos family and their housekeeper, after his DNA was purportedly found on a pizza crust at the scene of the quadruple murders. They discovered his DNA on the crust of a Domino's pizza — one of two delivered to the Savopoulos home May 14 as the family was held hostage inside — a source familiar with the investigation said. The pizza apparently was paid for with cash left in an envelope on the porch. The next morning, Savvas Savopoulos's personal assistant dropped off a package containing $40,000 in cash at the home, according to the officials and police documents.

The bodies of Savopoulos, along with his wife, Amy, their 10-year-old son Philip and the family's housekeeper, Veralicia Figueroa, were discovered the afternoon of May 14 after firefighters responded to reports of a fire. D.C. Police Chief Cathy Lanier says the killings are likely not a random crime and police have issued an arrest warrant for the 34-year-old Daron Dylon Wint, who is described as 5'7 and 155 lbs and might also go by the name "Steffon." Wint apparently used to work at American Iron Works, where Savvas Savopoulos was CEO and president. The neighborhood is home to numerous embassies and diplomatic mansions as well as the official residence of Vice President Joe Biden and his wife. "Right now you have just about every law enforcement officer across the country aware of his open warrant and are looking for him," says Lanier. "I think even his family has made pleas for him to turn himself in."

Gravitational Anomalies Beneath Mountains Point To Isostasy of Earth's Crust 83

from the give-and-take dept.
StartsWithABang writes: Imagine you wanted to know what your acceleration was anywhere on Earth; imagine that simply saying "9.81 m/s^2" wasn't good enough. What would you need to account for? Sure, there are the obvious things: the Earth's rotation and its various altitudes and different points. Surely, the farther away you are from Earth's center, the less your acceleration's going to be. But what might come as a surprise is that if you went up to the peak of the highest mountains, not only would the acceleration due to gravity be its lowest, but there'd also be less mass beneath your feet than at any other location.

"There is a general veil of suspicion that is placed on every American now. Every American is somehow said to be under suspicion because we are collecting the records of every American," Paul said. The questions is what did the "filibuster" really accomplish? The speeches caused a delay in Senate business but it's unclear what larger effect, if any, that will have.

Security Researchers Wary of Wassenaar Rules 31

Posted by samzenpus
from the rules-of-the-game dept.
msm1267 writes: The Commerce Department's Bureau of Industry and Security today made public its proposal to implement the controversial Wassenaar Arrangement, and computer security specialists are wary of its language and vagaries. For starters, its definition of "intrusion software" that originally was meant to stem the effect of spying software such as FinFisher and Hacking Team, has also apparently snared many penetration testing tools. Also, despite the Commerce Department's insistence that vulnerability research does not fall under Wassenaar, researchers say that's up for interpretation.
