Research into carbon storage in Arctic tundra reveals unexpected insight into ecosystem resiliency

When UC Santa Barbara doctoral student Seeta Sistla and her adviser, environmental studies professor Josh Schimel, went north not long ago to study how long-term warming in the Arctic affects carbon storage, they had made certain assumptions.

Video: Invasive crazy ants are displacing fire ants in areas throughout southeastern US

Invasive "crazy ants" are displacing fire ants in areas across the southeastern United States, according to researchers at The University of Texas at Austin. It's the latest in a history of ant invasions from the southern hemisphere and may prove to have dramatic effects on the ecosystem of the region.

Gene involved in neurodegeneration keeps clock running

Northwestern University scientists have shown a gene involved in neurodegenerative disease also plays a critical role in the proper function of the circadian clock.

Vicious cycle: Obesity sustained by changes in brain biochemistry

With obesity reaching epidemic levels in some parts of the world, scientists have only begun to understand why it is such a persistent condition. A study in the Journal of Biological Chemistry adds substantially to the story by reporting the discovery of a molecular chain of events in the brains of obese rats that undermined their ability to suppress ap

World's biggest ice sheets likely more stable than previously believed

For decades, scientists have used ancient shorelines to predict the stability of today's largest ice sheets in Greenland and Antarctica. Markings of a high shoreline from three million years ago, for example – when Earth was going through a warm period – were thought to be evidence of a high sea level due to ice sheet collapse at that time. This assumption has led many scientists to think that if

Stem-cell-based strategy boosts immune system in mice

Raising hopes for cell-based therapies, UC San Francisco researchers have created the first functioning human thymus tissue from embryonic stem cells in the laboratory. The researchers showed that, in mice, the tissue can be used to foster the development of white blood cells the body needs to mount healthy immune responses and to prevent harmful autoimmune reactions.

Fast and painless way to better mental arithmetic? Yes, there might actually be a way

In the future, if you want to improve your ability to manipulate numbers in your head, you might just plug yourself in. So say researchers who report in the Cell Press journal Current Biology on May 16 on studies of a harmless form of brain stimulation applied to an area known to be important for math ability.

World's melting glaciers making large contribution to sea rise

While 99 percent of Earth's land ice is locked up in the Greenland and Antarctic ice sheets, the remaining ice in the world's glaciers contributed just as much to sea rise as the two ice sheets combined from 2003 to 2009, says a new study led by Clark University and involving the University Colorado Boulder.

Promising treatment for progeria within reach

"This study is a breakthrough for our research group after years of work. When we reduce the production of the enzyme in mice, the development of all the clinical symptoms of progeria is reduced or blocked. We have also studied cultured cells from children with progeria, and can see that when the enzyme is inhibited, the growth of the cells increases by the same mechanism as in mouse cells," says

Asian lady beetles use biological weapons against their European relatives

Once introduced for biological pest control, Asian lady beetle Harmonia axyridis populations have been increasing uncontrollably in the US and Europe since the turn of the millennium. The species has been proliferating rapidly in Germany; conservationists fear that the Asian lady beetle will out-compete native beetle species.

The developmental genetics of space and time

Albert Erives, associate professor in the University of Iowa Department of Biology, and his graduate student, Justin Crocker, currently a postdoctoral researcher at the Howard Hughes Medical Institute (HHMI) Janelia Farm Research Campus, have conducted a study that reveals important and useful insights into how and why developmental genes often take inputs from two independent "morphogen concentra

Jekyll into Hyde: Breathing auto emissions turns HDL cholesterol from 'good' to 'bad'

Academic researchers have found that breathing motor vehicle emissions triggers a change in high-density lipoprotein (HDL) cholesterol, altering its cardiovascular protective qualities so that it actually contributes to clogged arteries.

HiRISE Mars camera reveals hundreds of impacts each year

Scientists using images from NASA's Mars Reconnaissance Orbiter, or MRO, have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 feet (3.9 meters) across. Researchers have identified 248 new impact sites on parts of the Martian surface in the past decade, using images from the spacecraft to determine when the craters
