Study published in Science also finds answers to the question: How do cells know to grow?

Researchers at Huntsman Cancer Institute (HCI) at the University of Utah and a collaborator at the University of California at Santa Cruz report they have developed a unique computational approach to investigate a regulatory network for gene expression that is implicated in cell growth and development. The study was published today in the journal Science.

“When studying the genome of

Maggie Hart, a South Dakota School of Mines and Technology paleontology student, recently found a rare, beaked whale that washed ashore on St. Catherine’s Island off the coast of Georgia.

At the time of her discovery in late July, Hart, a master’s degree candidate from Brea, Calif., was working on the St. Catherine’s Island Sea Turtle Conservation Program. In her studies of sea turtles, Hart is collaborating with Mike Knell of Council Bluffs, Iowa. Knell also is a Te

Mayo Clinic researchers have used a comparative genomic strategy to demonstrate a causative link between eosinophils, a rare type of white blood cell, and asthma. Their research shows that the presence of these unique blood cells is absolutely required for the development of asthma. The details of this animal-based study appear in the Sept. 17, 2004, issue of Science, the journal of the American Association for the Advancement of Science (AAAS).

For more than a century, scientists

A new study by researchers at Joslin Diabetes Center sheds light on the key mechanisms by which new pancreatic beta cells normally form in response to insulin resistance. These findings may some day help researchers devise ways of staving off full-blown diabetes.

Insulin resistance is a condition in which the body needs increasing amounts of insulin to function properly, including keeping blood glucose levels in the normal range. It is a major contributor to type 2 diabetes, obesi

The way that HIV disables the body’s natural defences against retroviruses is not as well understood as recent studies suggest, according to new research published in the Open Access journal Retrovirology. Klaus Strebel and his colleagues from NIH found that the HIV encoded Vif protein does not need to destroy the enzyme APOBEC3G within infected cells to disable it. This latest finding has serious implications for the design of antivirals to fight HIV.

APOBEC3G is one of the most

Multidisciplinary teams to study animal movement, genetic links to outside world

How exactly do animals move? How do organisms adapt to newly acquired genes? What genetic forces draw members of an ecological community together? And does social behavior originate in nature, nurture or both? To tackle these and other major questions in biology, the National Science Foundation (NSF) today announced six new awards totaling nearly $30 million over five years from its Frontiers in Integrat
