Wind, humidity and rainfall combined precisely to create Monday's massive killer tornado in Oklahoma. The awesome amount of energy released dwarfed the power of the atomic bomb that leveled Hiroshima.

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.

Environment is not the only factor in shaping regulatory patterns—and it might not even be the primary factor, according to a new Rice University study that looks at how cells' protein networks relate to a bacteria's genome.

Microsoft is the last of the three big video game console makers to unveil its latest gaming system. Tuesday's unveiling comes nearly eight years after the Xbox 360 went on sale. It follows last fall's debut of Nintendo's Wii U and a preview in February of the upcoming PlayStation 4 from Sony.

Researchers at University of Cincinnati have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources – lakes and rivers – at a significantly higher rate than the currently used filtering technology made of activated carbon. They report their results today at the 113th General Meeting of the American Society for Microbiology.

How does the bacterium Shigella—the cause of a deadly diarrheal disease—detect that it's in a human host? Ohio University scientists have found that a biological "RNA thermometer" monitors whether the environment is right for the bacterium to produce the factors it needs to survive within the body, according to a study published May 21 in the journal PLOS ONE.

John Cassidy in The New Yorker: When the Great Recession struck, U.S. policymakers did what mainstream textbooks recommend: they introduced monetary and fiscal-stimulus programs, which helped offset the retrenchments and job losses in the private sector. In Europe, austerity has been the order of the day, and it still is. Nearly five years after the financial crisis, governments are still trimming spending and cutting benefits in a vain attempt to bring down their budget deficits. The big mystery isn’t why austerity has failed to work as advertised: anybody familiar with the concept of “aggregate demand” could explain that one. It is why an area with a population of more than three hundred million has stuck with a policy prescription that was discredited in the nineteen-twenties and thirties. The stock answer, which is that austerity is necessary to preserve the euro, doesn’t hold up. At this stage, austerity is the biggest threat to the euro. If the recession lasts for very much longer, political unrest is sure to mount, and the currency zone could well break up. So why is this woebegone approach proving so sticky? Some of the answers can be found in a timely and suitably irreverent new book by Mark Blyth, a professor of political economy at Brown: “Austerity: The History of a Dangerous Idea.” Adopting a tone that is by turns bemused and outraged, Blyth traces the intellectual and political roots of austerity back to the Enlightenment, and the works of John Locke, David Hume, and Adam Smith. But he also provides a sharp analysis of Europe’s current predicament, explaining how an unholy alliance of financiers, central bankers, and German politicians foisted a draconian and unworkable policy on an unsuspecting populace.

cervesaebraciator writes "According to Quartz, '[Anjan Contractor's] Systems & Materials Research Corporation just got a six month, $125,000 grant from NASA to create a prototype of his universal food synthesizer. But Contractor, a mechanical engineer with a background in 3-D printing, envisions a much more mundane — and ultimately more important — use for the technology. He sees a day when every kitchen has a 3-D printer, and the earth's 12 billion people feed themselves customized, nutritionally-appropriate meals synthesized one layer at a time, from cartridges of powder and oils they buy at the corner grocery store. Contractor's vision would mean the end of food waste, because the powder his system will use is shelf-stable for up to 30 years, so that each cartridge, whether it contains sugars, complex carbohydrates, protein or some other basic building block, would be fully exhausted before being returned to the store.' No word yet on whether anyone other than the guy trying to sell the technology thinks it'll make palatable food." Read more of this story at Slashdot.

On May 20, 2013, NASA and NOAA satellites observed the system that generated severe weather in the south central United States and spawned the Moore, Okla., tornado.

Ninety-seven teams from 28 Colorado schools participated in last week's car competitions hosted by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL).
