Scientists probe DNA of 'Evolution Canyon' fruit flies, find drivers of change

Science Daily - Mon, 07/07/2014 - 8:16pm
Scientists have long puzzled over the genetic differences between fruit flies that live hardly a puddle jump apart in a natural environment known as “Evolution Canyon” in Mount Carmel, Israel. Even with migration, cross-breeding, and near-extinction of whole populations, the environment is the driving force in the fruit-fly gene pool in Evolution Canyon, according to new research.

Uber Is Now Cheaper Than a New York City Taxi

Slashdot - Mon, 07/07/2014 - 7:58pm
redletterdave writes Uber announced in a blog post on Monday it would cut the prices of its UberX service in New York City by 20% — but it's only for a limited time. Uber says this makes it cheaper to use UberX than taking a taxi. Consumers like Uber's aggressive pricing strategy but competitors — and some of its own drivers — are not as happy. UberX, Uber’s cheaper service usually hosted by regular people driving basic sedans rather than fancy black cars, also cut its rates by 25% last week in the Bay Area, including San Francisco, San Jose, and Oakland. As a result of that announcement, Uber said its service was effectively “45% cheaper than a taxi.”

Neuroeconomists confirm Warren Buffett's wisdom: Brain research suggests an early warning signal tips off smart traders

Science Daily - Mon, 07/07/2014 - 7:25pm
Investment magnate Warren Buffett has famously suggested that investors should try to 'be fearful when others are greedy and be greedy only when others are fearful.' That turns out to be excellent advice, according to the results of a new study that looked at the brain activity and behavior of people trading in experimental markets where price bubbles formed.

Summer jobs are good for kids, says study

Science Daily - Mon, 07/07/2014 - 7:25pm
Teenagers who work at summer or evening jobs gain a competitive advantage later in life, a new study shows. Developing early knowledge of the working world and how to manage in it, they are more likely to find good employment and earn more money in the future. The more hours that 15-year-olds work, particularly during the school term when they have to learn to manage their time, the better their career prospects, says one researcher.

Building much smaller, greener electronics: Atom-scale, ultra-low-power computing devices to replace transistor circuits

Science Daily - Mon, 07/07/2014 - 7:25pm
The digital age has resulted in a succession of smaller, cleaner and less power-hungry technologies since the days the personal computer fit atop a desk, replacing mainframe models that once filled entire rooms. Desktop PCs have since given way to smaller and smaller laptops, smartphones and devices that most of us carry around in our pockets. Scientists are now developing atom-scale, ultra-low-power computing devices to replace transistor circuits.

Of non-marijuana drug users in the ER, nearly all are problem drug users

Science Daily - Mon, 07/07/2014 - 7:24pm
Of emergency patients who reported any drug other than marijuana as their primary drug of use, 90.7 percent met the criteria for problematic drug use. Among patients who reported cannabis (marijuana) as their primary drug, almost half met the criteria for having a drug problem, according to a study.

World's biggest-ever flying bird discovered: Twice as big as the royal albatross

Science Daily - Mon, 07/07/2014 - 7:24pm
Scientists have identified the fossilized remains of an extinct giant bird that could be the biggest flying bird ever found. With an estimated 20- to 24-foot wingspan, the creature surpassed the previous record holder -- an extinct bird named Argentavis magnificens -- and was twice as big as the royal albatross, the largest flying bird today. Computer simulations show that the bird's long slender wings helped it stay aloft despite its enormous size.

Neandertal trait in early human skull suggests that modern humans emerged from complex labyrinth of biology and peoples

Science Daily - Mon, 07/07/2014 - 7:24pm
Re-examination of a circa 100,000-year-old archaic early human skull found 35 years ago in Northern China has revealed the surprising presence of an inner-ear formation long thought to occur only in Neandertals.

The quantum dance of oxygen: Proposal for a new phase of the element, when atoms dance in quartets

Science Daily - Mon, 07/07/2014 - 7:23pm
Under extremely high pressure conditions oxygen molecules group into quartets and give rise to a “dance of their magnetic moments”. This results in magnetic properties never previously observed in these conditions and in theory points to the existence of a new phase of the element, called epsilon 1.

Tractor Beam Created Using Water Waves

Slashdot - Mon, 07/07/2014 - 7:10pm
KentuckyFC writes The idea that light waves can push a physical object is far from new. But a much more recent idea is that a laser beam can also pull objects like a tractor beam. Now a team of Australian physicists has used a similar idea to create a tractor beam with water waves that pulls floating objects rather than pushes them. Their technique is to use an elongated block vibrating on the surface of water to create a train of regular plane waves. When the amplitude of these waves is small, they gradually push the surface of the water along, creating a flow that pushes floating objects with it. However, when the amplitude increases, the waves become non-linear and begin to interact with each other in a complex way. This sets up a flow of water on the surface in the opposite direction to the movement of the waves. The result is that floating objects--ping pong balls in the experiment--are pulled towards the vibrating block, like a tractor beam.

Book Review: Data-Driven Security: Analysis, Visualization and Dashboards

Slashdot - Mon, 07/07/2014 - 6:24pm
benrothke writes There is a not so fine line between data dashboards and other information displays that provide pretty but otherwise useless and unactionable information; and those that provide effective answers to key questions. Data-Driven Security: Analysis, Visualization and Dashboards is all about the later. In this extremely valuable book, authors Jay Jacobs and Bob Rudis show you how to find security patterns in your data logs and extract enough information from it to create effective information security countermeasures. By using data correctly and truly understanding what that data means, the authors show how you can achieve much greater levels of security. Keep reading for the rest of Ben's review.
