Many women struggling to have a baby turn to in-vitro fertilization to improve their chances, and then face further uncertainty and anxiety when confronted with the decision of whether to use frozen or fresh embryos. A new study by a researcher at Yale School of Public Health and co-authors in China finds an insignificant difference in live birth rates between the two methods. (more…)
AUSTIN, Texas — Biologists at The University of Texas at Austin have developed a method for rapidly screening hundreds of thousands of potential drugs for fighting infections, an innovation that holds promise for combating the growing scourge of antibiotic-resistant bacteria. The method involves engineering bacteria to produce and test molecules that are potentially toxic to themselves. (more…)
Tübinger Neurowissenschaftler erforschen mit transkranieller Magnetstimulation das Zusammenspiel von Nervenzellen in Gehirn und Rückenmark
Schon eine einzelne Handbewegung erfordert ein fein abgestimmtes Zusammenspiel der Nervenzellen: Damit das entsprechende Signal aus dem Gehirn im Rückenmark und dann im Muskel ankommt, müssen unterschiedliche neuronale Netzwerke einen gemeinsamen Rhythmus finden. Diesen komplexen Vorgang haben der Neurochirurg Professor Alireza Gharabaghi und sein Team in einer Studie an der Universität Tübingen aufgeschlüsselt. (more…)
By combining the use of drug-carrying nanoparticles with an organ-preserving machine, Yale researchers have developed a procedure that could help improve long-term outcomes for transplant recipients. (more…)
Infants within 2 miles of fracking sites more likely to have low birth weight
From North Dakota to Texas to Pennsylvania, hydraulic fracturing has transformed many places in America into energy powerhouses. But while some see the new energy boom as benefiting the local economy, others fear the potential health and environmental consequences. As U.S. and international policymakers grapple with whether the benefits of allowing hydraulic fracturing outweigh the costs, new evidence sheds light on a clear cost: an increase in the probability of poorer health for babies born near these sites.

For adults 60 and older, moderate daily walks improve attention and mental skills, UCLA study finds
Walking more than 4,000 steps a day can improve attention and mental skills in adults 60 and older, according to UCLA research published December 12 in a preprint edition of the Journal of Alzheimer’s Disease. (more…)
How a woman evaluates a man’s mating interest may be psychologically linked to her father’s behavior — and that can affect her own sexual behavior. (more…)
Researchers have discovered a key player in the molecular process that causes the communication breakdown between nerves in fatal muscle degeneration disease.
Researchers at the University of Arizona have taken an essential step forward in the quest to find the cause of amyotrophic lateral sclerosis, also known as ALS or Lou Gehrig’s disease. In the cells of flies, mice and humans with ALS, scientists at the UA have pinpointed a process that collapses when a critical protein’s blueprint is arrested on its way to protein construction. The study was published recently in the journal Cell Reports. (more…)
