A drug used to help control psychotic behavior in people with schizophrenia holds promise for controlling similar symptoms in the early stages of Alzheimer’s disease, a new study suggests.

What sets this drug – called quetiapine – apart from its contemporary counterparts is its apparent lack of serious side effects, such as confusion, muscle stiffness and imbalance in the joints, said Douglas Scharre, a study co-author and an associate professor of clinical neurology at Ohio State Universit

Why live in a glass house? For diatoms — tiny ocean-dwelling organisms that live in exquisitely ornate glass cases — the benefit turns out to be enormous.

In a paper published in the Sept. 13 issue of Science, Princeton scientists show that diatoms probably depend on glass to survive because the material facilitates photosynthesis. However, their study suggests that this domestic arrangement has a much bigger beneficiary: the entire planet, which owes its present-day, oxygen-rich and carbo

The average person’s heart pumps about a gallon of blood per minute, a rate that can easily triple or quadruple during exercise.

The rapid flow of blood through the body is a major roadblock to the use of gene therapy to cure diseases. When injected into the blood, vector viruses – which carry corrective genes – tend to shoot past the target organ or tissue rather than sticking to it, like grains of sand moving past stones in a fast-flowing river.

Now, University of Florida g

A new study confirms what some job seekers may suspect: The more effort people put into a job search, the more likely they are to find employment even in difficult economic times.

The Georgia Institute of Technology study also reveals how certain personality traits affect job-search behavior. For example, people tend to look harder for jobs and consequently have more success if they are: Optimistic and view the job loss as an opportunity to improve their position.

Using x-ray crystallography, researchers have produced the first images of a large molecular complex that helps shape and load the small, bubble-like vesicles that transport newly formed proteins in the cell. Understanding vesicle “budding” is one of the prerequisites for learning how proteins and other molecules are routed to their correct destinations in the cell.

In an article published in the September 19, 2002, issue of the journal Nature, Howard Hughes Medical Institute (HHMI) investi

Knowing an organism’s genome is good, but knowing what turns on its genes is even better.

Scientists have long searched for triggers that activate ribonucleic acid (RNA), a key component in gene expression. Now, in the Thursday, Sept. 19 issue of the journal Nature, scientists from the University of Wisconsin-Madison report that they have found an enzyme that activates RNA, which could lead to new ways of regulating genetic information.

“One of the big questions in molecular
