Can we spot volcanoes on alien worlds? Astronomers say 'yes'

Volcanoes display the awesome power of Nature like few other events. Earlier this year, ash from an Icelandic volcano disrupted air travel throughout much of northern Europe. Yet this recent eruption pales next to the fury of Jupiter's moon Io, the most volcanic body in our solar system. Now that astronomers are finding rocky worlds orbiting distant stars, they're asking the next logical questions: Do any of those worlds have volcanoes? And if so, could we detect them? Work by theorists at the Harvard-Smithsonian Center for Astrophysics suggests that the answer to the ...

NIH study shows how insulin stimulates fat cells to take in glucose

Using high-resolution microscopy, researchers at the National Institutes of Health have shown how insulin prompts fat cells to take in glucose in a rat model. The findings were reported in the Sept. 8 issue of the journal Cell Metabolism. By studying the surface of healthy, live fat cells in rats, researchers were able to understand the process by which cells take in glucose. Next, they plan to observe the fat cells of people with varying degrees of insulin sensitivity, including insulin resistance–considered a precursor to type 2 diabetes [http://diabetes.niddk.nih.gov]. ...

Iowa State study finds corn bred to contain beta-carotene is a good source of vitamin A

AMES, Iowa -- A new Iowa State University study has found that corn bred to contain increased levels of beta-carotene is a good source of vitamin A. The discovery gives added support to the promise of biofortified corn being developed through conventional plant breeding as an effective tool to combat vitamin A deficiency in developing countries. Beta-carotene is converted in the body to vitamin A. The researchers found that the beta-carotene in the corn was converted to vitamin A at a higher rate than what's predicted for corn, and higher than the rate for beta-carotene ...

A better way to treat HIV-infected children?

September 7, 2010 (4 pm ET) – Nevirapine is widely used to help prevent mother-to-child transmission of the HIV virus. In cases where the infants are nonetheless infected with HIV virus at birth, the standard treatment is to use protease inhibitors (PI) to reduce the amount of virus in their bloodstream. A new study involving 195 infants in South Africa found that children who were treated with PI and then switched to nevirapine were more likely to maintain virus below the detection threshold of the test than infants who continued to receive PI. Results of the study are ...

Harmful amyloid interferes with trash pickup for cells in Alzheimer's disease

Chemists at the University of California, San Diego, have identified how a protein that accumulates in the brains of people with Alzheimer's disease interferes with the ability of cells to get rid of debris. They also found a natural mechanism by which this protein, amyloid beta, itself may be discarded. Plaques of amyloid are a hallmark of the ailment, but no one is sure exactly how they contribute to catastrophic loss of memory and cognition. Scientists have begun to suspect that amyloid disables a structure called a proteasome, which chops up proteins that cells ...

Research on team loyalty yields new insight into 'die-hard' fandom

CHAMPAIGN, Ill. – There's a reason why some sports fans are referred to as "die-hards" – even after they move away, their loyalty to their hometown team endures, according to research by two University of Illinois professors. Scott Tainsky and Monika Stodolska, professors of recreation, sport and tourism, say new residents of a community maintain an attachment to their old team or former city as a way of asserting their identity after they move. "People new to a city don't just adopt their new hometown's team as a way to acclimate themselves in a new community," Tainsky ...

No need to worrry about deflation -- yet, U. of I. economist says

CHAMPAIGN, Ill. — A University of Illinois economist says consumers and investors concerned about the specter of deflation looming over an already bleak economic landscape should relax – for the time being, at least. Although the consumer price index is near zero, J. Fred Giertz says we're unlikely to see a prolonged deflationary period like the slump Japan experienced during its "lost decade" of the 1990s. "We're close to zero right now, but we're not below zero," said Giertz, an Institute of Government and Public Affairs economist who compiles a monthly barometer ...

Brown-led research divines structure for class of proteins

PROVIDENCE, R.I. [Brown University] — Most proteins are shapely. But about one-third of them lack a definitive form, at least that scientists can readily observe. These intrinsically disordered proteins (IDPs) perform a host of important biological functions, from muscle contraction to other neuronal actions. Yet despite their importance, "We don't know much about them," said Wolfgang Peti, associate professor of medical science and chemistry. "No one really worried about them." Now, Peti, joined by researchers at the University of Toronto and at Brookhaven National Laboratory ...

Brain mechanism linked to relapse after cocaine withdrawal

Addictive drugs are known to induce changes in the brain's reward circuits that may underlie drug craving and relapse after long periods of abstinence. Now, new research, published by Cell Press in the September 9 issue of the journal Neuron, uncovers a specific neural mechanism that may be linked to persistent drug-seeking behavior and could help to guide strategies for development of new therapies for cocaine addiction. Previous research has shown that the ventral tegmental area (VTA) is a brain region that is activated when cocaine users experience a craving for cocaine ...

Single gene regulates motor neurons in spinal cord

New York (September 8, 2010) – In a surprising and unexpected discovery, scientists at NYU Langone Medical Center have found that a single type of gene acts as a master organizer of motor neurons in the spinal cord. The finding, published in the September 9, 2010 issue of Neuron, could help scientists develop new treatments for diseases such as Lou Gehrig's disease or spinal cord injury. The "master organizer" is a member of the Hox family of genes, best known for controlling the overall pattern of body development. By orchestrating a cascade of gene expression in ...

MIT researchers find that interneurons are not all created equally

CAMBRIDGE, Mass. – A type of neuron that, when malfunctioning, has been tied to epilepsy, autism and schizophrenia is much more complex than previously thought, researchers at MIT's Picower Institute for Learning and Memory report in the Sept. 9 issue of Neuron. The majority of brain cells are called excitatory because they ramp up the action of target cells. In contrast, inhibitory cells called interneurons put the brakes on unbridled activity to maintain order and control. Epileptic seizures, as well as symptoms of autism and schizophrenia, have been tied to dysfunctional ...

Brain cells determine obesity -- not lack of willpower: Study

An international study has discovered the reason why some people who eat a high-fat diet remain slim, yet others pile on the weight. The study, led in Australia by the Monash Obesity and Diabetes Institute (MODI) at Monash University, found a high-fat diet causes brain cells to become insulated from the body preventing vital signals, which tell the body to stop eating and to burn energy, from reaching the brain efficiently. MODI director and Australian Life Scientist of the Year Professor Michael Cowley said there were two clear outcomes from the findings. 'We discovered ...
