Twenty-two years of dedicated research has finally resulted in success: In the journal Angewandte Chemie, a British team headed by Steven V. Ley at the University of Cambridge reports the first synthesis of azadirachtin, a natural compound that stops predatory insects from feeding.
Researchers at the University of Pittsburgh School of Medicine?s department of emergency medicine, in collaboration with the Allegheny County Fire Academy, have received a Federal Emergency Management Agency (FEMA) Fire Prevention and Safety grant to conduct a study designed to develop optimal methods of reducing acute cardiovascular risk resulting from exposure to heat stress during fire suppression.
The first comprehensive national survey of sexual attitudes, behaviors and problems among older adults in the United States has found that most people ages 57 to 85 think of sexuality as an important part of life and that the frequency of sexual activity, for those who are active, declines only slightly from the 50s to the early 70s.
Certain types of bacteria have sunlight-sensing molecules similar to those found in plants, according to a new study. Surprisingly, at least one species?responsible for causing the flu-like disorder Brucellosis?needs light to maximize its virulence.
University of Nottingham scientist Dr Stewart Martin has received a project grant from Breast Cancer Campaign, the only charity that specialises in funding independent breast cancer research throughout the UK.
Melbourne mental health researchers have succeeded in halving the number of relapses experienced by people with bipolar disorder which strikes two in 100 Australians, accounts for 12 percent of suicides each year and costs the country at least $1.5 billion annually.
Understanding the molecular structures of compounds that give certain fruits and vegetables their rich colors may help researchers find even more powerful cancer fighters, a new study suggests.
Test results from the Health Research and Development Center of the Ministry of Health and the Eijkman Insitute in Jakarta have confirmed that AS, a 28-year old female from Banjar Batu Gaing, Baraban, Kediri, Tabanan District in Bali is the most recent confirmed H5N1 case in Indonesia.
A nanoparticle drug delivery system designed for brain tumor therapy has shown promising tumor cell selectivity in a novel cell culture model devised by University of Nottingham scientists. The project, conducted jointly in the Schools of Pharmacy, Biomedical Sciences and Human Development, will be featured in the September issue of the Experimental Biology and Medicine.
Some biochemical processes, especially those in bacteria, have been so well studied it?s assumed that no discoveries are left to be made. Not so, it turns out, for Johns Hopkins researchers who have stumbled on the identity of an enzyme that had been a mystery for more than 30 years. The report appears in the May 15 issue of Structure.
