Proteins may be more of a factor in shaping regulatory patterns than environment, according to a new study that looks at how cells' protein networks relate to a bacteria's genome. The lab of computer scientist Luay Nakhleh ar Rice University reported in the Proceedings of the National Academy of Sciences that when environmental factors are eliminated from an evolutionary model, mutations and genetic drift can give rise to the patterns that appear. They studied changes that show up in regulatory networks that determine the organism's characteristics. read more

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.

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.

NEW PRODUCT – SMT Breakout PCB for 48-QFN or 48-TQFP – 3 Pack! – Beguiled by a fancy new chip that is only available in a QFP or QFN pinout? This breakout PCB set will make your life much much easier and get you prototyping faster than ever. One side has a 48-QFP pin out with traces going to two rows of 0.1″ spaced holes, the other has 48-QFN (7mm body). Solder your chip to either side and you’re ready to rock on any solderless breadboard. There’s even a THM pad on the opposite side of the QFN body pad so you can fill it with solder for a heat sink and/or connect a wire to it (say when the pad must be grounded). Each item comes with three PCBs, each PCB is identical and can support either a 7mm square QFP or 7mm square QFN chip. Standard thickness PCBs, with 0.7″ spacing between the two rows. The PCBs may come on a supporting strip of PCB, simply snap them off to use! In stock and shipping now!
