Validating maps of the brain's resting state

Validating maps of the brain's resting state

Kick back and shut your eyes. Now stop thinking.

You have just put your brain into what neuroscientists call its resting state. What the brain is doing when an individual is not focused on the outside world has become the focus of considerable research in recent years. One of the potential benefits of these studies could be definitive diagnoses of mental health disorders ranging from bipolar to post-traumatic stress disorders.

University of Tennessee professor finds prehistoric rock art connected; maps cosmological belief

University of Tennessee professor finds prehistoric rock art connected; maps cosmological belief

It is likely some of the most widespread and oldest art in the United States. Pieces of rock art dot the Appalachian Mountains, and research by University of Tennessee, Knoxville, anthropology professor Jan Simek finds each engraving or drawing is strategically placed to reveal a cosmological puzzle.

Recently, the discoveries of prehistoric rock art have become more common. With these discoveries comes a single giant one—all these drawing and engravings map the prehistoric peoples' cosmological world.

States vary widely on success rates for minorities in drug treatment programs

A University of Iowa study reveals significant disparities between minority and white clients in success rates for completing substance abuse treatment programs. Moreover, these disparities vary widely from state to state.

"Our findings suggest that for most states there's something amiss," says Stephan Arndt, Ph.D., UI professor of psychiatry and biostatistics. "There are strong racial and ethnic disparities for people in being able to complete substance abuse treatment programs successfully, and those disparities are something we need to set as targets to remove.

What do memories look like?

Oscar Wilde called memory "the diary that we all carry about with us." Now a team of scientists has developed a way to see where and how that diary is written.

The team, led by Don Arnold and Richard Roberts of USC, engineered microscopic probes that light up synapses in a living neuron in real time by attaching fluorescent markers onto synaptic proteins – all without affecting the neuron's ability to function.

Outlook is grim for mammals and birds as human population grows

COLUMBUS, Ohio – The ongoing global growth in the human population will inevitably crowd out mammals and birds and has the potential to threaten hundreds of species with extinction within 40 years, new research shows.

Scientists at The Ohio State University have determined that the average growing nation should expect at least 3.3 percent more threatened species in the next decade and an increase of 10.8 percent species threatened with extinction by 2050.

New data on islet autoantibodies in young children defines early type 1 diabetes development

New York, NY, June 19, 2013 – A decade-long JDRF-funded study led by the Institute of Diabetes Research in Helmholtz Zentrum München, Germany, is providing a deeper understanding of the link between autoantibodies and the risk of developing type 1 diabetes (T1D), highlighting the importance of pre-diabetes research into possible preventions for the disease. The study, "Seroconversion to Multiple Islet Autoantibodies and Risk of Progression to Diabetes in Children," was published today in The Journal of the American Medical Association.

Breakthrough research of essential molecule reveals important targets in diabetes and obesity

DETROIT – Insulin is the most potent physiological anabolic agent for tissue-building and energy storage, promoting the storage and synthesis of lipids, protein and carbohydrates, and inhibiting their breakdown and release into the circulatory system. It also plays a major role in stimulating glucose entry into muscle tissue, where the glucose is metabolized and removed from the blood following meals. But gaps exist in understanding the precise molecular mechanisms by which insulin regulates glucose uptake in fat and muscle cells.

Moffitt Cancer Center researchers identify genetic variants predicting aggressive prostate cancers

Researchers at Moffitt Cancer Center and colleagues at Louisiana State University have developed a method for identifying aggressive prostate cancers that require immediate therapy. It relies on understanding the genetic interaction between single nucleotide polymorphisms (SNPs). The goal is to better predict a prostate cancer's aggressiveness to avoid unnecessary radical treatment.

Their study was published in the online journal PLOS ONE in April.

An environmentally friendly battery made from wood

Taking inspiration from trees, scientists have developed a battery made from a sliver of wood coated with tin that shows promise for becoming a tiny, long-lasting, efficient and environmentally friendly energy source. Their report on the device — 1,000 times thinner than a sheet of paper — appears in the journal Nano Letters.

New canary seed is ideal for gluten-free diets in celiac disease

A new variety of canary seeds bred specifically for human consumption qualifies as a gluten-free cereal that would be ideal for people with celiac disease (CD), scientists have confirmed in a study published in ACS' Journal of Agricultural and Food Chemistry.
