In the March issue of GSA Today, seven scientists from six countries, led by Jan Zalasiewicz of the University of Leicester, propose a realignment of the terms "geochronology" and "chronostratigraphy" in an attempt to resolve the debate of whether units of the Geological Time Scale should have a...

NASA's Fermi Gamma-ray Space Telescope orbits our planet every 95 minutes, building up increasingly deeper views of the universe with every circuit. Its wide-eyed Large Area Telescope sweeps across the entire sky every three hours, capturing the highest-energy form of light -- gamma rays -- from...

An international research team, led by the Research Institute of the McGill University Health Centre, has demonstrated that rapid and point-of-care tests (POC) for syphilis are as accurate as conventional laboratory tests. The findings, which were published in PLOS ONE, call for a major change in approach to syphilis testing...

Patients with more severe depression show at least as good clinical benefit from 'low-intensity' interventions, such as self help books and websites, as less severely ill patients, suggests a new article. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/E...

A new study found that ship noise affects crab metabolism, with the largest crabs faring the worst, and found little evidence that crabs acclimatize to noise over time. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/Z...

New US Department of Agriculture regulations have altered what foods schools offer for lunch, but schools cannot require students to eat specific foods. Researchers have now implemented an intervention using the behavioral science principle known as "libertarian paternalism" which led junior-senior...

Though it's most often associated with disorders like diabetes, scientists have shown how the pathway of insulin and insulin-like peptides plays another critical role in the body -- helping to regulate learning and memory. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/H...

Among patients with heart failure with preserved ejection fraction, long-term treatment with the medication spironolactone improved left ventricular diastolic function but did not affect maximal exercise capacity, patient symptoms, or quality of life, according to a new study. Fuente :...

An international team led by the University of Alabama at Birmingham (UAB) has documented a 78 percent decline in the number of nests of the critically endangered leatherback sea turtle (Dermochelys coriacea) at the turtle's last stronghold in the Pacific Ocean. Fuente :...

Fingers are one of the first body parts to suffer from the cold and popular fingerless texting gloves can lead to frostbite and in worst cases, amputation, says an expert. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/F...

Scientists have uncovered an unexpected, but important molecular mechanism of mTOR inhibitor resistance and a novel drug combination that reverses this resistance using low dose arsenic in mice. The mTOR pathway is hyperactivated in 90 percent of glioblastomas, the most lethal brain cancer in...

Scientists are discovering how the evolution of ecosystems has to be taken into account when speculating between different geological eras. Go back to the time of the dinosaurs or to the single-celled organisms at the origins of life, and it is obvious that ecosystems existing more than 65 million years ago and around four...

An estimated 300,000 U.S. patients get surgical site infections every year, and while the causes are varied, a new study suggests that some who get an infection can blame it partly on their genes. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/B...

Because confronting fear won’t always make it go away, researchers suggest that people with phobias must alter memory-driven negative attitudes about feared objects or events to achieve a more lasting recovery from what scares them the most.

Researchers are testing the power of holography to artificially stimulate cells in the eye, with hopes of developing a new strategy for bionic vision restoration. Computer-generated holography, they say, could be used in conjunction with a technique called optogenetics, which uses gene therapy to deliver light-sensitive...

Plentiful food can accelerate the spread of infections, scientists have shown in a study of water fleas. Scientists studying bacterial infections in tiny water fleas have discovered that increasing their supply of food can speed up the spread of infection.
