Deforestation Causes Cooling in northern U.S., Canada

Deforestation, considered by scientists to contribute significantly to global warming, has been shown by a Yale-led team to actually cool the local climate in northern latitudes, according to a paper published Nov. 17 in Nature.

“If you cut trees in the boreal region, north of 45 degrees latitude, you have a net cooling effect,” says Xuhui Lee, the study’s principal investigator and professor of meteorology at the Yale School of Forestry & Environmental Studies. “You release carbon into the atmosphere by cutting down trees, but you increase the albedo effect — the reflection of sunlight.” (more…)

Research Sheds New Light on Body Parts’ Sensitivity to Environmental Changes

Science

EAST LANSING, Mich. — Research by a team of Michigan State University scientists has shed new light on why some body parts are more sensitive to environmental change than others, work that could someday lead to better ways of treating a variety of diseases, including Type-2 diabetes.

The research, led by assistant zoology professor Alexander Shingleton, is detailed in the recent issue of the Proceedings of the Library of Science Genetics. (more…)

Yale Researchers Discover Promising Anti-HIV Agents

Health

Researchers at Yale University have discovered new chemical compounds that prevent HIV from replicating in human T-cells. These compounds could result in new, highly effective HIV treatments that are 10 to 2000 times more potent than HIV drugs now on the market. (more…)

Microsoft Acquires Video Content Discovery Company VideoSurf

Technology

REDMOND, Wash., and SAN MATEO, Calif. — Nov. 22, 2011 — Microsoft Corp. has announced the acquisition of California-based video discovery technology company VideoSurf Inc.

Founded in 2006, VideoSurf offers a back-end computer vision technology that “sees” frames inside videos to make discovering content fast, easy and accurate. Over time, Microsoft will integrate this technology across its entertainment platform to augment the Xbox 360 ecosystem and evolve search and discovery of entertainment content on Xbox LIVE. (more…)

A Tailored Pair of Genes

Science

*For ancient plants, two genes were definitely better than one*

In the wake of the disaster that killed the dinosaurs, the ancestors of today’s crop plants reinvented themselves.

They doubled their genomes, and in that single act set the stage for feeding the world 60 million years later.

In a study published in the Nov. 16 issue of the journal Nature, researchers from the University of Minnesota and other institutions recount how sequencing the genome of a model, alfalfa-like legume revealed the monumental benefits that flowed when the ancestor of legumes acquired an extra copy of every gene.

UCLA Team Develops Highly Efficient Method for Creating Flexible, Transparent Electrodes

Science

As the market for liquid crystal displays and other electronics continues to drive up the price of indium — the material used to make the indium tin oxide (ITO) transparent electrodes in these devices — scientists have been searching for a less costly and more dynamic alternative, particularly for use in future flexible electronics.

MU Engineers Developing Military Applications for Smartphones

Technology, Weapons

COLUMBIA, Mo. – Tracking military targets? The University of Missouri’s College of Engineering has an app for that.

Engineers from the MU College of Engineering, with funding from the U.S. Army/Leonard Wood Institute, have enhanced popular smartphones to be able to find and track targets. In addition, the engineers have developed ad hoc networks so that soldiers can relay smartphone information without using the internet. (more…)
