Some caregivers of critical care patients prefer doctors to keep their opinions on life support decisions to themselves, according to new research that challenges long-held beliefs in the critical care community.
The ice age may have caused the extinction of dinosaurs and the woolly mammoths may have disappeared because of declining sources of food, but extinction doesn’t always have to be due to environmental triggers, as scientists at the University of California, and the University of Chicago recently found.
The veil is being lifted from the once unseen world of molecular activity. Not so long ago only the final products were visible and scientists were forced to gauge the processes behind those products by ensemble averages of many molecules. The limitations of that approach have become clear with the advent of technologies that allow for the observation and manipulation of single molecules.
Irvine, Calif. -- A UC Irvine study has found that a gene called TOMM40 appears twice as often in people with Alzheimer's disease than in those without it. Alzheimer's, for which there is no cure, is the leading cause of elderly dementia.
RIVERSIDE, Calif. -- Citrus researchers at the University of California, Riverside have released a new mandarin (or tangerine) for commercial production. Named 'DaisySL' for Daisy seedless, the new fruit is finely textured and juicy, with a rich, sweet and distinctive flavor when mature. Its rind is smooth and thin, and bears a deep orange color.
African village dogs are not a mixture of modern breeds but have directly descended from an ancestral pool of indigenous dogs, according to a Cornell-led genetic analysis of hundreds of semi-feral African village dogs.
Advances in ecology increasingly reveal that conventional agricultural practices have detrimental effects on the landscape ecology, creating problems for long-term sustainability of crops. In a series of sessions at the Ecological Society of America's Annual Meeting, ecologists will present their ideas on how our agricultural practices can take lessons from natural environments.
Irvine, Calif. -- Researchers have identified what they believe is the original source of malignant malaria: a parasite found in chimpanzees in equatorial Africa.
Thin-film zeolite membranes with tiny, molecule-sized pores are one step closer to replacing the energy-intensive processes now used in industrial separations, a group of academic researchers is reporting.
Durham, NC -- For avid fishermen and anglers, the largemouth bass is a favorite freshwater fish with an appetite for minnows. A new study finds that once they evolved to eat other fish, largemouth bass and fellow fish-feeders have remained relatively unchanged compared with their insect- and snail-eating cousins.
For the first time in nearly 50 years, a population of a nearly extinct frog has been rediscovered in the San Bernardino National Forest's San Jacinto Wilderness. Biologists from the U.S.
Ozone exposure, even at levels deemed safe by current clean air standards, can have a significant and negative effect on lung function, according to researchers at the University of California Davis.
Dr. Dentcho Genov, an assistant professor of physics and electrical engineering at Louisiana Tech University and a Louisiana Optical Network Initiative (LONI) Institute fellow, is featured in the most recent issue of Nature Physics, one of the most respected and prestigious physics journals in the world.
Ytterbium was discovered in 1878, but until it recently became useful in atomic clocks, the soft metal rarely made the news. Now ytterbium has a new claim to scientific fame.
By substituting a single atom in a molecule widely used to purify water, researchers at Sandia National Laboratories have created a far more effective decontaminant with a shelf life superior to products currently on the market.
