Overeating May Double Risk of Memory Loss

New research suggests that consuming between 2,100 and 6,000 calories per day may double the risk of memory loss, or mild cognitive impairment (MCI), among people age 70 and older. The study was released today and will be presented at the American Academy of Neurology’s 64th Annual Meeting in New Orleans April 21 to April 28, 2012. MCI is the stage between normal memory loss that comes with aging and early Alzheimer’s disease.

Researchers Develop Method to Examine Batteries—From the Inside

Researchers at Cambridge University, Stony Brook University, and New York University have developed methodology, based on magnetic resonance imaging (MRI), to examine batteries without destroying them. Their technique creates the possibility of improving battery performance and safety by serving as a diagnostic of its internal workings.

New Research Reveals How Protein Protects Cells From HIV Infection

A novel discovery by researchers at NYU Langone Medical Center and colleagues reveals a mechanism by which the immune system tries to halt the spread of HIV. Harnessing this mechanism may open up new paths for therapeutic research aimed at slowing the virus’ progression to AIDS. The study appears online ahead of print today in Nature Immunology.

Complex Wiring of the Nervous System May Rely on a Just a Handful of Genes and Proteins

SamPfaffchalk.jpg

Researchers at the Salk Institute have discovered a startling feature of early brain development that helps to explain how complex neuron wiring patterns are programmed using just a handful of critical genes. The findings, published February 3 in Cell, may help scientists develop new therapies for neurological disorders, such as amyotrophic lateral sclerosis (ALS), and provide insight into certain cancers.

New Study by Biologist Finds Dramatic Improvements and Persistent Challenges for Women in Science

The underrepresentation of women in science has received significant attention. However, there have been few studies in which longitudinal data were used to assess changes over time. In a paper recently published in the journal BioScience, Richard B. Primack, professor of biology at Boston University; Krista L. McGuire, assistant professor of biological sciences at Barnard College, Columbia University; and Elizabeth C. Losos, adjunct professor at Duke University and president and CEO of the Organization for Tropical Studies, find that women in the field of ecological studies have experienced dramatic improvements, but persistent challenges remain.

Advances in studying genes mean that scientists in evolutionary developmental biology or “evo-devo” can now explain more clearly than ever before how bats got wings, the turtle got its shell and blind cave fish lost their eyes, says evolutionary biologist Craig Albertson, who studies cichlid fishes.
