Millions of people at risk of becoming blind could one day be helped by an Oak Ridge National Laboratory technology originally intended to understand semiconductor defects.
Researchers at New York University have determined the location in the brain where involuntary attention enhances visual processing. The researchers, from NYU's Department of Psychology and Center for Neural Science, found that attending to, or selectively processing information from a given location without directing our eyes to that location, enhances performance in visual tasks as well as the neural activity underlying the processing of ensuing images. The results are published in the latest issue of the journal Neuron.
Scientists investigating the link between PCBs, pesticides and Parkinson's disease have demonstrated new and intricate reactions that occur in certain brain cells, making them more vulnerable to injury after exposures. The group describes how PCBs disrupt dopamine neurons, and how low levels of the fungicide maneb can injure those cells.
Despite a proliferation of gun registration requirements, bans on specific firearms and "zero tolerance" policies for guns in schools over the past three decades, the jury is still out on whether these laws help prevent gun violence, according to a new review of studies in the American Journal of Preventive Medicine.
College campuses provide a captive audience for cigarette-makers, but a new review of tobacco intervention studies suggests that universities are also effective sites for anti-smoking efforts.
Researchers opened the hood of yeast, worm, and fly cells and their wiring analysis of protein interactions in the three more fully explains the diversity of eukaryotic life on the planet.
The National Institutes of Health have awarded $8.7 million to USC to study genetic and environmental factors that influence tobacco and alcohol use among adolescents in China and the United States.
Keeping a gun locked, unloaded, and storing ammunition in a locked and separate location can lower the risk of unintentional injuries and suicide among youth, according to a study in the February 9 issue of JAMA.
Researchers at the University of Washington have blended the past with the present in the fight against cancer, synthesizing a promising new compound form an ancient Chinese remedy that uses cancer cell's rapacious appetite for iron to make them a target.
UCI researchers have determined that chronic nicotine exposure worsens some Alzheimer's-related brain abnormalities, contradicting the common belief that nicotine can actually be used to treat the disease.
To help promising scientists establish their first independent labs in Central Europe, HHMI and EMBO are launching the EMBO/HHMI Startup Grants, three-year awards of $75,000 annually.
By inserting corrective genes into the brain, scientists studying small monkeys prevented brain damage by producing therapeutic levels of GDNF, a protein that helps nourish brain cells.
Assessing the risk of potential exposure to variant Creutzfeldt-Jakob Disease , the human form of 'mad cow disease,' from blood transfusion was the focus of the FDA Transmissible Spongiform Encephalopathies Advisory Committee today. In response, Pall Corporation presented the latest scientific data on its new prion reduction technology. The Leukotrap. Affinity Prion Reduction Filter, expected to be launched commercially in Europe this spring, removes infectious prions from red cells, the most widely transfused blood component.
Physicians group develops commercially available insulin assay that does not use mice or fetal calf serum.
University of Toronto researchers have discovered an ample source of stem cells in an uncharted part of the umbilical cord, providing new hope for bone marrow transplants and tissue repair.
Harvard-trained family physician and former Washington Post journalist Susan Okie will talk about her new book, FED UP! WINNING THE WAR AGAINST CHILDHOOD OBESITY, published by Joseph Henry Press -- an imprint of National Academies Press.
Participants will sample wines that illustrate the effects of regional climate on wine quality, as well as wines containing a compound that may protect against cancer and heart disease.
Throughout the year, the American Association for Cancer Research (AACR) selects faculty members in minority-serving institutions who have shown excellence and dedication in the field of cancer research. They come from institutions which are historically Black, predominantly Hispanic, and Tribal Colleges and Universities.
Each year, the American Association for Cancer Research (AACR) presents awards to minority scholars who have made an impact in cancer research, and show potential to continue to do so in the future.
The American Association for Cancer Research (AACR) has granted a scholarship to two outstanding women in cancer research through the AACR-Women in Cancer Research (WICR) Brigid G. Leventhal Scholar Award in Cancer Research program.
When elderly people need assistance with the activities of daily life, one might assume that the best people to care for them would be the ones who know them best--their spouses. But, as a team of researchers at the University of Pittsburgh report in this month's issue of the Journal of the American Geriatrics Society, being married to one's caregiver could be a prescription for abuse.
A steroid hormone released during the metabolism of progesterone, the female sex hormone, reduces the brain's response to stress, according to research in rats. The scientists found evidence that the progesterone metabolite allopregnanolone reduces the brain's response to corticotropin-releasing factor (CRF), a peptide hormone that plays an important role in the stress response in animals. The finding could provide a new drug target for treating anxiety and depression in women.
Scientists at Washington University in St. Louis have developed the first mathematical model of a canine cardiac cell that incorporates a vital calcium regulatory pathway , with implications for life-threatening cardiac arrhythmias, or irregular heartbeats.
Analysis by Indiana University School of Medicine researchers of 278 parental views on sexually transmitted diseases vaccination for children found that severity of possible infection and effectiveness of a vaccine weighed heavily in the decision-making process for parents.
A new study has shown a stroke-prevention drug designed to be an improvement over prior treatments is less cost-effective for most patients than warfarin, the blood thinner with a 50-year history of helping prevent blood clots and strokes. The study, conducted by researchers at Washington University School of Medicine in St. Louis found, however, that the new drug would be cost-effective for those atrial fibrillation patients whose risk of bleeding is high.
