Valium puts humans and amoeba to sleep

Biologists at University of California, San Diego (UCSD) have discovered that the popular sedative Valium has similar effects on the social amoeba Dictyostelium discoideum as it does in humans. Their surprising finding that Valium, as well as a "natural Valium" molecule found in human brains, causes the social amoeba to enter a dormant or "sleep" phase, may provide new insights into how cells in higher organisms, including humans, communicate with each other.

Vitamin A's paradoxical role in influencing symmetry during embryonic development revealed

In this week's journal Nature, scientists at the Salk Institute for Biological Studies report that they have solved one of the "holy grail" puzzles of developmental biology: the existence of a mechanism that insures that the exterior of our bodies is symmetrical while inner organs are arranged asymmetrically.

Discovery may pave way for immunotherapies for prostate cancer

Using a common chemotherapy agent, researchers at UCLA's Jonsson Cancer Center and the Department of Pathology and Laboratory Medicine found a way to move an important biomarker expressed in prostate cancer, shaking it loose from one location in a cell – where it could not be accessed by blood – to another, easier to target area.

New laser technology for more precise cancer treatments

Tom Cowan’s team is thinking smaller, but with big impact. Particle accelerators are a key research tool in a high energy physicist’s arsenal, but they take up a lot of space - miles and miles of it. But at the University of Nevada, Reno, smaller is better.

Laboratory model of immune system overcomes ethical constraints on studies of hematopoietic stem cells in humans

Scientists at St. Jude Children’s Research Hospital have joined with colleagues at several other institutions to develop a laboratory model of the human immune system. This model will allow scientists to study ways for improving the results of hematopoietic stem cell (HSC) transplantation without putting patients at risk.

African Americans and Caucasians viewing African American faces display extremely similar changes in the activity of brain structures that respond to emotional events

The changes occur in the amygdala, a region of the brain that serves as an "alarm" to activate a cascade of other biological systems to protect the body in times of danger, said Matthew D. Lieberman, assistant professor of psychology at UCLA and lead author of the study.

Clues about how alcoholic behavior is “switched” on

As part of an ongoing effort to understand the biochemical basis of alcohol abuse, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have published two studies on how modulating receptors for dopamine - a chemical “signaler” in the brain’s reward circuits - affects drinking behavior in mice and rats.

Metabolic syndrome costing four times that for all other patients

It is well known that hypertension, diabetes, and obesity are each taking a toll on Americans' health, but according to a new analysis, metabolic syndrome, a condition characterized by a combination of these and/or other risk factors, is fast becoming one of the nation's costliest health concerns.
