Nondigestible compounds in apples may help prevent obesity-related disorders

Scientists at Washington State University have concluded that nondigestible compounds in apples - specifically, Granny Smith apples - may help prevent disorders associated with obesity. The study, thought to be the first to assess these compounds in apple cultivars grown in the Pacific Northwest, appears in October's print edition of the journal Food Chemistry.

Neural recordings can be used to forecast spontaneous decisions

You're waiting at a bus stop, expecting the bus to arrive any time. You watch the road. Nothing yet. A little later you start to pace. More time passes. "Maybe there is some problem", you think. Finally, you give up and raise your arm and hail a taxi. Just as you pull away, you glimpse the bus gliding up. Did you have a choice to wait a bit longer? Or was giving up too soon the inevitable and predictable result of a chain of neural events?

Finding ways to rejuvenate "immunological age" of the brain

How the brain ages is still largely an open question - in part because this organ is mostly insulated from direct contact with other systems in the body, including the blood and immune systems. In research that was recently published in Science, Weizmann Institute researchers Prof. Michal Schwartz of the Neurobiology Department and Dr. Ido Amit of Immunology Department found evidence of a unique "signature" that may be the "missing link" between cognitive decline and aging.

New approach to solve global challenges in food security, emerging diseases and biodiversity loss

Solving global challenges in food security, emerging diseases and biodiversity loss requires evolutionary thinking, argues a new study published online in Science Express that was co-authored by Bruce Tabashnik of the University of Arizona College of Agriculture and Life Sciences.

Scientists reveal that human brain can trigger random behavior

Many of the choices we make are informed by experiences we've had in the past. But occasionally we're better off abandoning those lessons and exploring a new situation unfettered by past experiences.

Scientists discover mechanism that resists cancer drugs in estrogen-positive breast cancer

Scientists have discovered a previously unknown mechanism by which estrogen prepares cells to divide, grow and, in the case of estrogen-positive breast cancers, resist cancer drugs. The researchers say the work reveals new targets for breast cancer therapy and will help doctors predict which patients need the most aggressive treatment.

New study exposes negative consequences of sleep deprivation among teens

While American paediatricians warn sleep deprivation can stack the deck against teenagers, a new study from Taylor & Francis reveals youth's irritability and laziness aren't down to attitude problems but lack of sleep.

Understanding how neurons encode information

Nathan Urban, interim provost and the Dr. Frederick A. Schwertz Distinguished Professor of Life Sciences, and Robert Kass, professor of statistics and machine learning, have received a $930,000 grant from the National Science Foundation to apply biological and statistical neuroscience approaches in order to create a better overall understanding of how neurons encode information.

Study provides support for new understanding of the immune system

A study published in the journal Science provides support for a new-and still controversial-understanding of the immune system. The research was conducted by collaborators in the U.S. and Europe, including Robert Cramer, PhD, an assistant professor of microbiology and immunology at the Geisel School of Medicine and member of the Dartmouth Lung Biology Center, and Kelly Shepherdson, PhD, at the time a graduate student in Cramer's lab.
