Mating Mites Trapped in Amber Reveal Sex Role Reversal

ANN ARBOR, Mich.— In the mating game, some female mites are mightier than their mates, new research at the University of Michigan and the Russian Academy of Sciences suggests. The evidence comes, in part, from 40 million-year-old mating mites preserved in Baltic amber.

In a paper published March 1 in the Biological Journal of the Linnean Society, researchers Pavel Klimov and Ekaterina Sidorchuk describe an extinct mite species in which the traditional sex roles were reversed. (more…)

Sleep More to Avoid Car Accidents and Bad Days at Work

Less than seven hours of sleep each night is leading to a host of sleep-related problems including drowsy driving and difficulty concentrating at work, according to two new studies released on Thursday.

Roughly one-third of adults in 12 states reported getting less than seven hours of sleep each night with about the same number saying they’ve unintentionally dozed off during the day, according to one of the studies on sleep-related behavior from the Centers for Disease Control and Prevention.

JQI Physicists Demonstrate Coveted ‘Spin-Orbit Coupling’ in Atomic Gases

Technique suggests an avenue for creating new kinds of superconductivity

COLLEGE PARK, Md. — Physicists at the Joint Quantum Institute (JQI), a collaboration of the University of Maryland and the National Institute of Standards and Technology (NIST), have for the first time caused a gas of atoms to exhibit an important quantum phenomenon known as spin-orbit coupling. Their technique opens new possibilities for studying and better understanding fundamental physics and has potential applications to quantum computing, next-generation “spintronics” devices and even “atomtronic” devices built from ultracold atoms.

Harmful Illusions Bedevil Ideas About Free Markets and Imprisonment, UChicago Professor Writes

The United States prizes freedom above most other civic values, yet Bernard Harcourt believes the notion is widely misunderstood and inconsistently applied.

Freedom from government interference is a key tenet of the free market system that the United States champions, but Harcourt notes that Americans expect vigorous government action in imprisoning criminals. The result is a deep inconsistency, he argues, for even as the United States preaches freedom in the marketplace, it maintains the world’s highest incarceration rate. (more…)

Spitzer Captures Infrared Rays From a Sunflower

The various spiral arm segments of the Sunflower galaxy, also known as Messier 63, show up vividly in this image taken in infrared light by NASA’s Spitzer Space Telescope. Infrared light is sensitive to the dust lanes in spiral galaxies, which appear dark in visible-light images. Spitzer’s view reveals complex structures that trace the galaxy’s spiral arm pattern.

Messier 63 lies 37 million-light years away — not far from the well-known Whirlpool galaxy and the associated Messier 51 group of galaxies. (more…)

Just Like Me: Online Training Helpers More Effective When They Resemble Students

Opposites don’t always attract. A study from North Carolina State University shows that participants are happier – and perform better – when the electronic helpers used in online training programs resemble the participants themselves.

“It is important that the people who design online training programs understand that one size does not fit all,” says Dr. Lori Foster Thompson, an associate professor of psychology at NC State and co-author of the study. “Efforts to program helper agents that may be tailored to individuals can yield very positive results for the people taking the training.” (more…)

Mapping Food Deserts

EAST LANSING, Mich. — Maps are great for showing where things are. They’re also good for showing where things aren’t.

Two Michigan State University professors have developed interactive maps that offer a visual perspective of urban food deserts. By using GIS (geographic information systems) technology, they are showing, rather than simply telling, how urban residents are losing access to fresh produce and balanced nutrition. (more…)

Cloud Computing: Making Rain From Blue-Sky Thinking

*Microsoft cloud solutions help customers cut costs, generate new revenue streams and provide added services to end users*

REDMOND, Wash. — March 3, 2011 — This week’s edition of Businessweek includes a story about the shift taking place in the development and deployment of applications and services by using cloud computing to cut costs, streamline IT management and respond more quickly to changes in end-user demand. Microsoft is cited as one of the companies taking the lead in this area and in moving organizations from their existing operations and services to the cloud and taking advantage of increased efficiency and new opportunities along the way.

To be sure, the economic gains that are possible through cloud computing are significant – one customer saw a reduction in IT management costs by three-quarters, in part from moving to Windows Azure. But cloud computing has the potential to expand beyond the realm of budget line items to that of lines of software code, creating new tools and services that lead to new computing experiences, expanded business opportunities, better services for customers, and, ultimately, new jobs and economic growth.
