Congressional Report: US Power Grid Highly Vulnerable To Cyberattack
An anonymous reader writes "Despite warnings that a cyberattack could cripple the nation's power supply, a U.S. Congressional report (PDF) finds that power companies' efforts to protect the power grid are insufficient. Attacks are apparently commonplace, with one utility claiming they fight off some 10,000 attempted attacks every month. The report also found that while most power companies are complying with mandatory standards for protection, few do much else above and beyond that to protect the grid. 'For example, NERC has established both mandatory standards and voluntary measures to protect against the computer worm known as Stuxnet. Of those that responded, 91% of IOUs [Investor-Owned Utilities], 83% of municipally- or cooperatively-owned utilities, and 80% of federal entities that own major pieces of the bulk power system reported compliance with the Stuxnet mandatory standards. By contrast, of those that responded to a separate question regarding compliance with voluntary Stuxnet measures, only 21% of IOUs, 44% of municipally- or cooperatively-owned utilities, and 62.5% of federal entities reported compliance.'"

Google Chrome 27 Is Out: 5% Faster Page Loads
An anonymous reader writes "Google on Tuesday released Chrome version 27 for Windows, Mac, and Linux. The new version features a big boost to page loads (now 5 percent faster on average) as well as significant updates for developers. The speed improvement is thanks to the introduction of 'smarter behind-the-scenes resource scheduling,' according to Google. Starting with this release, the scheduler more aggressively uses an idle connection and demotes the priority of preloaded resources so that they don’t interfere with critical assets."

Lost in translocation? How bird song could help save species
Translocation – or moving animals to safer places – is a vital tool for saving species from extinction. Many factors influence the success of these new populations, including habitat quality, predators, capture and release techniques, the number and sex of individuals, and their genetic diversity. Now new research, the first of its kind suggests bird song could also be important.

Special Ops Takes Its Manhunts Into Space
Wired reports on a cluster of mini-satellites that will soon be launched into orbit that will assist U.S. special forces personnel during manhunts. "SOCOM is putting eight miniature communications satellites, each about the size of a water jug, on top of the Minotaur rocket that's getting ready to launch from Wallops Island, Virginia. They’ll sit more than 300 miles above the earth and provide a new way for the beacons to call back to their masters." When special forces are able to tag their target, the target can be tracked and located through the use of satellites and cell towers, but coverage is poor in many areas of the world. The satellites going up in September will help to fill in some gaps. "This array of configurable 'cubesats' is designed to stay aloft for three years or more. Yes, it will serve as further research project. But 'operators are going to use it,' Richardson promised an industry conference in Tampa last week."

Aurora Attackers Were Looking For Google's Surveillance Database
An anonymous reader writes "When in early 2010 Google shared with the public that they had been breached in what became known as the Aurora attacks, they said that the attackers got their hands on some source code and were looking to access Gmail accounts of Tibetan activists. What they didn't make public is that the hackers have also accessed a database containing information about court-issued surveillance orders that enabled law enforcement agencies to monitor email accounts belonging to diplomats, suspected spies and terrorists. Whether this was the primary goal of the attacks as well as how much information was exfiltrated is unknown. current and former U.S. government officials interviewed by the Washington Post say that the database in question was possibly accessed in order to discover which Chinese intelligence operatives located in the U.S. were under surveillance."

Changing cancer's environment to halt its spread
By studying the roles two proteins, thrombospondin-1 and prosaposin, play in discouraging cancer metastasis, scientists have identified a five-amino acid fragment of prosaposin that significantly reduces metastatic spread in mouse models of prostate, breast and lung cancer. The findings suggest that a prosaposin-based drug could potentially block metastasis in a variety of cancers.

Study reveals how fishing gear can cause slow death of whales
Using a "patient monitoring" device attached to a whale entangled in fishing gear, scientists showed for the first time how fishing lines changed a whale's diving and swimming behavior. The monitoring revealed how fishing gear hinders whales' ability to eat and migrate, depletes their energy as they drag gear for months or years, and can result in a slow death.

Dart Is Not the Language You Think It Is
An anonymous reader writes "Seth Ladd has an excellent write-up of Dart: 'When Dart was originally launched, many developers mistook it for some sort of Java clone. In truth, Dart is inspired by a range of languages such as Smalltalk, Strongtalk, Erlang, C#, and JavaScript. Get past the semicolons and curly braces, and you'll see a terse language without ceremony. ... Dart understands that sometimes you just don’t feel like appeasing a ceremonial type checker. Dart’s inclusion of an optional type system means you can use type annotations when you want, or use dynamic when that’s easier. For example, you can explore a new idea without having to first think about type hierarchies. Just experiment and use var for your types. Once the idea is tested and you’re comfortable with the design, you can add type annotations."

EPA Makes a Rad Decision
New submitter QuantumPion writes "The Environmental Protection Agency released draft guidelines last month that could significantly relax radiation hazard standards in the case of a radiological event in the United States by using risk-based decisions. The goal is to have limits that make sense in an emergency that are different from the limits in day-to-day life. From the article: 'Currently, the only guidance are the extremely strict standards that apply for EPA Superfund sites and nuclear plant decommissioning, which are as low as 0.010–0.025 rem/year, far below the natural background levels in the U.S. of 0.300 rem/year, and even well below the average amount of radioactive materials that Americans eat each year. And these guidelines aren’t really different from the 1992 PAG, except in the area of long-term cleanup standards and, perhaps, standards for resettlement. What’s the big deal here? As radworkers, we’re allowed to get 5 rem/year. 2 rem/year doesn’t rate a second thought. ... No one has ever been harmed by 5 rem/year, so setting emergency levels at 2 rem/year is pretty mild and more than reasonable. ... Think of it this way. The situations covered by these new guidelines are similar to someone dying of thirst who has the chance to drink fresh water having 2,000 pCi per gallon of radium in it. While the safe drinking water levels are 20 pCi/gal for Ra, 2,000 pCi/gal is of no threat, especially if you’re going to die from imminent dehydration. Of course, a bag of potato chips has 3,500 picocuries, so go figure.'"

Ask Slashdot: Can Yahoo Actually Stage a Comeback?
Nerval's Lobster writes "Fresh off purchasing Tumblr for $1.1 billion, Yahoo has moved to the next stage of what's becoming a company-wide reboot: fixing Flickr, the photo-sharing service that it acquired in 2005 and subsequently allowed to languish. Yahoo boosted Flickr accounts' individual storage capacity to one free terabyte, revamped the Website's overall look, and launched a new Flickr app for Google Android, among other tweaks. Yahoo CEO Marissa Mayer clearly wants her company to fight toe-to-toe on features with Google and Facebook, but she faces a long road ahead of her: not only does she need to streamline Yahoo's cumbersome corporate structure and product portfolio into something that resembles fighting shape, but she needs to reverse the general perception that Yahoo is teetering on the edge of history's trash-bin, with an aging customer base and unexciting features. The question is, could anyone actually pull it off? Is Yahoo capable of an Apple-style turnaround, or are its current actions merely delaying the inevitable?"
