SAN FRANCISCO — Satellite observations have revealed the first direct evidence of smoke from Arctic wildfires drifting over the Greenland ice sheet, tarnishing the ice with soot and making it more likely to melt under the sun. (more…)
PASADENA, Calif. – Scientists with NASA’s Cassini mission have spotted what appears to be a miniature, extraterrestrial likeness of Earth’s Nile River: a river valley on Saturn’s moon Titan that stretches more than 200 miles (400 kilometers) from its “headwaters” to a large sea. It is the first time images have revealed a river system this vast and in such high resolution anywhere other than Earth. (more…)
A decade ago, a British philosopher put forth the notion that the universe we live in might in fact be a computer simulation run by our descendants. While that seems far-fetched, perhaps even incomprehensible, a team of physicists at the University of Washington has come up with a potential test to see if the idea holds water. (more…)
Friends may help reduce package delivery costs
Every day trucks ply the neighborhoods of America, driving “the last mile” of the delivery chain for goods ordered through Amazon, eBay, and other online retailers. (more…)
Groundbreaking research by a team of UCLA physicians and engineers demonstrates that prostate cancer — long identifiable only through painful, hit-or-miss biopsies — can be diagnosed far more easily and accurately using a new image-guided, targeted biopsy procedure. (more…)
Berkeley Lab scientists develop a new nanotech tool to probe solar-energy conversion
If nanoscience were television, we’d be in the 1950s. Although scientists can make and manipulate nanoscale objects with increasingly awesome control, they are limited to black-and-white imagery for examining those objects. Information about nanoscale chemistry and interactions with light—the atomic-microscopy equivalent to color—is tantalizingly out of reach to all but the most persistent researchers.
But that may all change with the introduction of a new microscopy tool from researchers at the Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) that delivers exquisite chemical details with a resolution once thought impossible. The team developed their tool to investigate solar-to-electric energy conversion at its most fundamental level, but their invention promises to reveal new worlds of data to researchers in all walks of nanoscience.

A changing climate has implications on biodiversity without any doubt. Species in the past have been sensitive to changes in the climate; that has been proved time and again by the fossilized remains and pollen distribution studies. It has been seen or can be concluded safely that climate changes have led to extinction of species in one area and colonization in another. (more…)
Antidepressants are the most widely used treatment for people with moderate to severe depression.
However, up to two thirds of people with depression don’t respond fully to this type of treatment. New findings have shown cognitive behavioural therapy (CBT), provided in addition to usual care, can reduce symptoms of depression and help improve patients’ quality of life.
This is the first large-scale trial to test the effectiveness of CBT – a type of talking psychotherapy- given in addition to usual care that includes antidepressants. The National Institute for Health Research Health Technology Assessment (NIHR HTA)-funded CoBalT study aimed to determine the best ‘next step’ treatment for people whose depression had not responded to medication alone.
