Permafrost threatened by rapid retreat of Arctic sea ice 
The rate of climate warming over northern Alaska, Canada, and Russia could more than triple during periods of rapid sea ice loss, according to a new study led by the National Center for Atmospheric Research (NCAR).

Large-scale experiments needed to predict global change
Ecosystems are constantly exchanging materials through the movement of air in the atmosphere and water in lakes and rivers. The effects of humans, however, are another major source of connections among ecosystems.

New Climate Report Foresees Big Changes
A new federal report says the rise in levels of atmospheric carbon dioxide is influencing climate patterns and will produce an uneven national map of harms and benefits.

Satellites illuminate pollution's influence on clouds
Clouds have typically posed a problem to scientists using satellites to observe the lowest part of the atmosphere, where humans live and breathe, because they block the satellite's ability to capture a clear, unobstructed view of Earth's surface. It turns out, however, that these "obstructions" are worth a closer look, as clouds and their characteristics actually serve a valuable role in climate

Seeing clearly despite the clouds
Satellites taking atmospheric measurements might now be able to see blue skies as clearly as optimists do. Researchers have found a way to reduce cloud-induced glare when satellites measure blue skies on cloudy days, by as much as ten-fold in some cases. The result might lead to more accurate estimates of the amount of sunlight penetrating the atmosphere, improving climate models.

Disabling mouse enzyme increases fertility
Changing the sugars attached to a hormone produced in the pituitary gland increased fertility levels in mice nearly 50 percent, a research group at Washington University School of Medicine in St. Louis has found. The change appears to alter a reproductive "thermostat," unveiling part of an intricate regulatory system that may one day be used to enhance human fertility.

Window of opportunity for restoring oaks small
Communities of Oregon white oak were once widespread in the Pacific Northwest’s western lowlands, but, today, they are in decline. Fire suppression, conifer and invasive plant encroachment, and land use change have resulted in the loss of as much as 99 percent of the oak communities historically present in some areas of the region.

New Molecules Could Change the Face of Explosives Detection
Chemists have developed complex molecules for use in portable sensors that quickly and reliably detect the presence of plastic explosives, a pressing need for soldiers in Iraq. The molecules can also identify which type of explosive is present, allowing security personnel to quickly determine which material they are dealing with.

Hot climate could shut down plate tectonics
A new study of possible links between climate and geophysics on Earth and similar planets finds that prolonged heating of the atmosphere can shut down plate tectonics and cause a planet's crust to become locked in place.

Lab in a drop
Analysis and diagnosis in a chip format are coming of age, but their practical application has been limited because until now, the sample usually had to be prepared separately and on a nonminiaturized scale. Jürgen Pipper and his team at the Institute of Bioengineering and Nanotechnology in Singapore want to change this.

Climate modelers see modern echo in '30s Dust Bowl
Climate scientists using computer models to simulate the 1930s Dust Bowl on the U.S Great Plains have found that dust raised by farmers probably amplified and spread a natural drop in rainfall, turning an ordinary drying cycle into an agricultural collapse.

Patients in therapy to overcome addictions have a new arena to test their coping skills—the virtual world. A new study by University of Houston Associate Professor Patrick Bordnick found that a virtual reality (VR) environment can provide the climate necessary to spark an alcohol craving so that patients can practice how to say “no” in a realistic and safe setting.
