Sounds from helmets colliding explored as alternative to understanding football collisions

Science Daily - Thu, 02/04/2015 - 5:27pm
When football helmets collide, they produce an unmistakable sound. New research of those sound waves produces a unique understanding of the forces involved in those collisions and, perhaps one day, researchers hope, inexpensive sensing methods may be developed for a safer game.

Black holes don’t erase information, scientists say

Science Daily - Thu, 02/04/2015 - 5:27pm
Shred a document, and you can piece it back together. But send information into a black hole, and it's lost forever. A new study finds that -- contrary to what some physicists have argued for the years -- information is not lost once it has entered a black hole. The research presents explicit calculations showing how information is, in fact, preserved.

Google 'Makes People Think They Are Smarter Than They Are'

Slashdot - Thu, 02/04/2015 - 5:09pm
HughPickens.com writes Karen Knapton reports at The Telegraph that according to a study at Yale University, because they have the world's knowledge at their fingertips, search engines like Google or Yahoo make people think they are smarter than they actually are giving people a 'widely inaccurate' view of their own intelligence that can lead to over-confidence when making decisions. In a series of experiments, participants who had searched for information on the internet believed they were far more knowledgeable about a subject that those who had learned by normal routes, such as reading a book or talking to a tutor. Internet users also believed their brains were sharper. "The Internet is such a powerful environment, where you can enter any question, and you basically have access to the world's knowledge at your fingertips," says lead researcher Matthew Fisher. "It becomes easier to confuse your own knowledge with this external source. When people are truly on their own, they may be wildly inaccurate about how much they know and how dependent they are on the Internet." In the tests searching for answers online leads to an illusion such that externally accessible information is conflated with knowledge "in the head" (PDF). This holds true even when controlling for time, content, and search autonomy during the task. "The Internet is an enormous benefit in countless ways, but there may be some trade-offs that aren't immediately obvious and this may be one of them," concludes Fisher. "Accurate personal knowledge is difficult to achieve, and the Internet may be making that task even harder."

Intel Launches SSD 750 Series Consumer NVMe PCI Express SSD At Under $1 Per GiB

Slashdot - Thu, 02/04/2015 - 4:25pm
MojoKid writes Today, Intel took the wraps off new NVMe PCI Express Solid State Drives, which are the first products with these high speed interfaces, that the company has launched specifically for the enthusiast computing and workstation market. Historically, Intel's PCI Express-based offerings, like the SSD DC P3700 Series, have been targeted for datacenter or enterprise applications, with price tags to match. However, the Intel SSD 750 Series PCI Express SSD, though based on the same custom NVMe controller technology as the company's expensive P3700 drive, will drop in at less than a dollar per GiB, while offering performance almost on par with its enterprise-class sibling. Available in 400GB and 1.2TB capacities, the Intel SSD 750 is able to hit peak read and write bandwidth numbers of 2.4GB/sec and 1.2GB/sec, respectively. In the benchmarks, it takes many of the top PCIe SSD cards to task easily and at $389 for a 400GB model, you won't have to sell an organ to afford one.

Statistical analysis reveals Mexican drug war increased homicide rates

Science Daily - Thu, 02/04/2015 - 4:13pm
In the short term, the Mexican government's war against drugs increased the average murder rate in regions subjected to military-style interventions, a new statistical analysis suggests. The Mexican government--beginning in December 2006 during former President Felipe Calderón's term and continuing through current President Enrique Peña Nieto's administration--has been fighting an internal war against drug traffickers. A 2013 report by Human Rights Watch estimates 60,000 people were killed between 2006 and 2012 as a result of the military interventions and drug cartels fighting each other for control of territory.

Microbes scared to death by virus presence

Science Daily - Thu, 02/04/2015 - 3:47pm
The microbe Sulfolobus islandicus can go dormant, ceasing to grow and reproduce, in order to protect themselves from infection by Sulfolobus spindle-shaped virus 9 (SSV9), researchers have discovered. The dormant microbes are able to recover if the virus goes away within 24 to 48 hours -- otherwise they die.

Road revolution by connecting vehicles: Computational framework for optimizing traffic flow

Science Daily - Thu, 02/04/2015 - 3:47pm
Drivers trying to get to work or home in a hurry know traffic congestion wastes a lot of time, but it also wastes a lot of fuel. In 2011, congestion caused people in US urban areas to travel an extra 5.5 billion hours and purchase an extra 2.9 billion gallons of fuel costing $121 billion. But despite the tangle of vehicles at busy intersections and interstate ramps, most of the country's highways are open road with vehicles occupying only about 5 percent of road surface. Researchers envision vehicles exchanging information -- such as location, speed, and destination -- to generate individualized instructions for drivers.

22 genetic variations that are associated with an increased risk of developing prostate cancer have been identified by an international team of researchers. Prostate cancer affects one out of every 6 men during their lifetime and is the second most common cause of cancer-related death for men in the United States, resulting in an estimated 27,500 deaths in 2015.

One test can predict which kids will become nearsighted

Science Daily - Thu, 02/04/2015 - 3:46pm
A study of 4,500 U.S. children over 20 years has identified a single test that can predict which kids will become nearsighted by the eighth grade: a measure of their current refractive error. The refractive error, or eyeglasses prescription, results from mismatches in the size and optical power of the eye that lead to blurry vision.

As Trade Restrictions Crumble, Airbnb Offers Rooms In Cuba

Slashdot - Thu, 02/04/2015 - 3:36pm
As reported by the Associated Press, and carried by the Washington Post, one major move toward normalized relations between Cuba and the United States has been made not by diplomats, but by entrepreneurs. Airbnb has opened its crowd-sourced roomfinding service to Cubans and Americans, such that American tourists visiting Havana can book space in private homes — as of today. From the article: “We believe that Cuba could become one of Airbnb’s biggest markets in Latin America,” said Kay Kuehne, regional director for Airbnb, the website and mobile app that allows users to book rooms in more than 1 million private homes around the world. “We are actually plugging into an existing culture of micro-enterprise in Cuba. The hosts in Cuba have been doing for decades what we just started doing seven years ago. ... Because of continuing restrictions under the U.S. embargo, the company’s Cuba listing will only be available to U.S. travelers visiting under one of 12 U.S.-government approved categories of legal travel, ranging from professional research to religious activities.”

EFF: Wider Use of HTTPS Could Have Prevented Attack Against GitHub

Slashdot - Thu, 02/04/2015 - 2:54pm
itwbennett writes The attack against GitHub was enabled by someone tampering with regular website traffic to unrelated Chinese websites, all of which used a JavaScript analytics and advertising related tool from Baidu. Somewhere on China's network perimeter, that analytics code was swapped out for code that transparently sent data traffic to GitHub. The reason GitHub's adversaries were able to swap out the code is because many of the Chinese websites weren't encrypting their traffic.
