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

ESA develops a smarter way to travel through space

As scientists demand more from space missions travelling to other worlds and beyond, traditional rocket technologies are beginning to show shortcomings. In response, ESA are helping to develop a new type of rocket engine, known as solar-electric propulsion, or more commonly, an ion engine, that can mark a whole new era of space exploration.

Solar-electric propulsion is ESA`s new spacecraft engine. It does not burn fuel as chemical rockets do; instead the technique converts sunlight into elec

Rutgers geneticists discover probable causes of hybrid plant vigor

Agricultural breeders have long observed that when plants or animals from different strains are interbred, the offspring tend to be stronger, healthier or generally more fit than either of their parents, although no one knew why this occurred. Now plant geneticists investigating the maize (corn) genome at Rutgers’ Waksman Institute of Microbiology have discovered a possible explanation for this phenomenon, known as heterosis or hybrid vigor.

The Rutgers findings, presented by research
