Police lineups in which distinctive individual marks or features are not altered can impair witnesses' ability to distinguish between innocent and guilty suspects, according to new research in Psychological Science, a journal of the Association for Psychological Science.
A University of Colorado Cancer Center study finds that three years post-bone marrow transplant, the incidence of severe chronic graft-versus-host disease was 44 percent in patients who had received transplants from matched, unrelated donors (MUD) and 8 percent in patients who had received umbilical cord blood transplants (CBT).
Researchers have assumed that natural selection drove frogs to take the evolutionary step to reproduce on land as a way for parents to avoid aquatic predators who feed on the eggs and tadpoles. A new study by a team including Cornell University frog biologists shows for the first time that some frogs hide eggs on land to reduce competition from other males who also want to fertilize those eggs.
Mechanical thrombectomy, a leading type of neurointerventional stroke treatment where a device can remove a blood clot in minutes, is essential for people experiencing a stroke, who stand to lose 2 million neurons every minute the artery is blocked. Equally essential is access to a hospital or health care system with a successful workflow in place that can deliver such treatment.
In molten sandstone extracted by prospectors a century ago, an international team of scientists has discovered microscopic crystals telling of unimaginable pressures and temperatures when a 12-kilometer asteroid formed Meteor Crater in northern Arizona some 49,000 years ago.
A new study presented at the Society of NeuroInterventional Surgery's (SNIS) 13th Annual Meeting in Boston found that the Opercular Score Index (OIS) is a practical, noninvasive scoring system that can be used to predict the strength and health of the vascular network in the brain (known as collateral robustness) and good clinical outcome among stroke patients undergoing endovascular recanalization.
Yellow fever virus (YFV), a close relative of Zika virus and transmitted by the same type of mosquito, is the cause of an often-fatal viral hemorrhagic fever and could spread via air travel from endemic areas in Africa to cause international epidemics.
Engineers from the University of Utah and the University of Minnesota have discovered that interfacing two particular oxide-based materials makes them highly conductive, a boon for future electronics that could result in much more power-efficient laptops, electric cars and home appliances that also don't need cumbersome power supplies.
A recent research report about one of the largest lithium brine and salt deposits in the world in Chile's Atacama Desert by geoscientists from UMass Amherst is the first to show that water and solutes flowing into the basin originate from a much larger than expected portion of the Andean Plateau. The massive evaporite deposit, 1,200 meters thick, appears to be draining an area far larger than a map-based or topographic watershed would suggest, says lead hydrologist David Boutt.
Aneurysms of the paraclinoid region of the internal carotid artery (ICA) and the interventions used to treat them often result in visual impairment. Researchers at Brigham and Women's Hospital, however, found that flow diversion demonstrates a higher rate of visual improvement and a lower rate of visual decline in patients with these types of aneurysms. Results from this new study were presented at the Society of NeuroInterventional Surgery's (SNIS) 13th Annual Meeting today in Boston.
