Scientists, Public Team Up to Discover Biodiversity

During the 2011 BioBlitz at Saguaro National Park Oct. 21-22, school children and volunteers teamed up with experts to embark on a 24-hour race to discover and tally as many of the park’s living creatures as possible in an effort to better understand the ecology and biodiversity of the Sonoran Desert.

Under an afternoon sun that is beating down much too relentlessly for this time of year, our group of eleven is scrambling up a hillside in Saguaro National Park just west of Tucson. (more…)

Surprisingly, people born between 1961 and 1981 are not isolated socially

Despite being stereotyped as a bunch of insecure underachievers, most members of Generation X lead active, balanced and happy lives, according to a long-term University of Michigan survey. (more…)

At one time or another, however briefly, many of the budding scientists Suzanne Alonzo works with in her laboratory or classroom have experienced a crisis of confidence — or, at the least, a bit of doubt about their academic path. (more…)

Researchers Use New Approach to Overcome Key Hurdle for Next-Generation Superconductors

Researchers from North Carolina State University have developed a new computational approach to improve the utility of superconductive materials for specific design applications – and have used the approach to solve a key research obstacle for the next-generation superconductor material yttrium barium copper oxide (YBCO).

A superconductor is a material that can carry electricity without any loss – none of the energy is dissipated as heat, for example. Superconductive materials are currently used in medical MRI technology, and are expected to play a prominent role in emerging power technologies, such as energy storage or high-efficiency wind turbines.

*Tap, Flick, Slide or Swipe: Samsung Advances Personal Computing Experiences With Just a Touch*

REDMOND, Wash. — Natural User Interfaces (NUI), such as touch, have been in development for years, but only recently have become a mainstream reality. Touch user interfaces have made computing more interactive, easier to use and more pervasive than ever, whether on a laptop, all-in-one PC or mobile phone.

In fact, over the past few years, the ability to control mobile phones, for example, with spot-on voice recognition or with simple touch gestures has redefined an industry. (more…)

More Power to the Cranberry: Study Shows the Juice is Better than Extracts at Fighting Bacterial Infections

With scientific evidence now supporting the age-old wisdom that cranberries, whether in sauce or as juice, prevent urinary tract infections, people have wondered if there was an element of the berry that, if extracted and condensed, perhaps in pill form, would be as effective as drinking the juice or eating cranberry sauce. A new study from researchers at Worcester Polytechnic Institute helps to answer that question. (more…)

*Evidence of water mass moving south 70 million years ago shows how warmth was distributed*

COLUMBIA, Mo. – New research from the University of Missouri indicates that Atlantic Ocean temperatures during the greenhouse climate of the Late Cretaceous Epoch were influenced by circulation in the deep ocean. These changes in circulation patterns 70 million years ago could help scientists understand the consequences of modern increases in greenhouse gases.

“We are examining ocean conditions from several past greenhouse climate intervals so that we can understand better the interactions among the atmosphere, the oceans, the biosphere, and climate,” said Kenneth MacLeod, professor of geological sciences in the College of Arts and Science. “The Late Cretaceous Epoch is a textbook example of a greenhouse climate on earth, and we have evidence that a northern water mass expanded southwards while the climate was cooling. At the same time, a warm, salty water mass that had been present throughout the greenhouse interval disappeared from the tropical Atlantic.” (more…)
