Does a junk food diet make you lazy? UCLA psychology study offers answer

Being overweight makes people tired and sedentary — not the other way around

A new UCLA psychology study provides evidence that being overweight makes people tired and sedentary — not the other way around.

Life scientists led by UCLA’s Aaron Blaisdell placed 32 female rats on one of two diets for six months. The first, a standard rat’s diet, consisted of relatively unprocessed foods like ground corn and fish meal. The ingredients in the second were highly processed, of lower quality and included substantially more sugar — a proxy for a junk food diet. (more…)

Genome-wide Atlas of Gene Enhancers in the Brain On-line

Collaboration Led by Berkeley Lab Researchers Creates High-Resolution Map of Gene Regulatory Elements in the Brain

Future research into the underlying causes of neurological disorders such as autism, epilepsy and schizophrenia, should greatly benefit from a first-of-its-kind atlas of gene-enhancers in the cerebrum (telencephalon). This new atlas, developed by a team led by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) is a publicly accessible Web-based collection of data that identifies and locates thousands of gene-regulating elements in a region of the brain that is of critical importance for cognition, motor functions and emotion.

“Understanding how the brain develops and functions, and how it malfunctions in neurological disorders, remains one of the most daunting challenges in contemporary science,” says Axel Visel, a geneticist with Berkeley Lab’s Genomics Division. “We’ve created a genome-wide digital atlas of gene enhancers in the human brain – the switches that tell genes when and where they need to be switched on or off. This enhancer atlas will enable other scientists to study in more detail how individual genes are regulated during development of the brain, and how genetic mutations may impact human neurological disorders.” (more…)

University of Maryland Researcher Asks – What Does Love Look Like?

COLLEGE PARK, Md. – What does love look like? A dozen roses delivered on an ordinary weekday? Breakfast in bed? Or just a knowing glance between lovers?

While outward displays of love are fairly easy to discern, a researcher in the College of Behavioral and Social Sciences is taking a decidedly “inward” approach to documenting this most complex of human emotions. (more…)
