Discovery of Three Faint Companions of Bright Stars Brings Historic Mount Wilson Telescope to Cutting Edge of Astronomy

Three small, faint stars, apparently locked in the gravitational embrace of much larger and brighter companions, have been discovered in the first light from a new infrared camera with innovative optics on the 100-inch telescope at the Mount Wilson Observatory in Pasadena, California.

“This is the first time the historic Mount Wilson telescope has looked at the universe through this new infrared eye, and already it is making new discoveries,” says Jian Ge, assistant professor of astronomy an

Although Controversial, Stem Cell Therapies Exhibit Potential in Biotechnology Markets

Stem cells have enormous potential for repairing damage to the body caused by disease, injury, or aging. When introduced into an injured area of a patient, a stem cell could survive and repopulate the region with different types of cells, forming normal tissue.

Stem cells also offer the prospect of treating many inherited diseases caused by a single, defective gene. Though other treatments are available, such as gene therapy, the longevity of benefits from stem cell treatment provides a tant

Genetic engineering could salvage once-promising anti-cancer agents

A group of anti-cancer agents that once produced dismal results in clinical trials could once again be a promising tool in fighting the deadly disease, thanks to research by a team of chemists at the University of Washington and in Germany.

The agents, called maytansinoids, were first discovered in the 1970s when scientists looked for tumor inhibitors in a rare Ethiopian plant. The same group of maytansinoids was later isolated from a new bacteria species. The compounds held great promise b

UCLA researchers check brain waves to predict effectiveness of antidepressants

A new UCLA Neuropsychiatric Institute study shows for the first time that measurable changes in the front of the brain can predict the effectiveness of an antidepressant within days of treatment — weeks before a patient begins to feel better.

Using quantitative EEG, a non-invasive computerized measurement of brain wave patterns, the researchers discovered that specific changes in brain-wave activity precede clinical changes brought on by medication. The new findings, published in the July e

How does serotonin effect depression

Depression investigators at The Research Institute of University Hospitals of Cleveland have zeroed in on the neurotransmitter serotonin, a brain chemical that regulates emotion. Their tactics: reduce serotonin levels in each study subject to learn who is vulnerable for developing major depression.

This new study, funded by the National Institute of Mental Health, is designed to help scientists better understand the role of serotonin in people who get major depression. By examining the way

NC State Scientist Discovers Mosquito Repellent in Tomatoes

A substance produced by tomatoes repels mosquitoes and other insects more effectively and is safer than DEET, the chemical most commonly used in insect repellents, a North Carolina State University scientist has discovered.

Indeed, work by Dr. Michael Roe, William Neal Reynolds Distinguished Professor of Entomology at NC State, showed that the natural compound found in tomatoes is so effective at repelling insects that the university patented the substance. The patent describes how the subs
