An Oak Ridge National Laboratory and University of Tennessee team has used the Department of Energy's Jaguar supercomputer to calculate the number of isotopes allowed by the laws of physics.

(Phys.org) -- Researchers at the SLAC National Accelerator Laboratory have captured the most detailed images to date of airborne soot particles, a key contributor to global warming and a health hazard.

Federal Food and Drug Administration officials approved a new weight-loss pill Wednesday, giving the nod to Belviq used in combination with a reduced-calorie diet and exercise to combat obesity.

Researchers from North Carolina State University have developed a new technique for controlling the crystalline structure of titanium dioxide at room temperature.

(Phys.org) -- Melanin – the pigment that colours skin, eyes and hair – could soon be the face of a new generation of biologically friendly electronic devices used in applications such as medical sensors and tissue stimulation treatments.

(Phys.org) -- The positive and sometimes unexpected impact of particle physics is well documented, from physicists inventing the World Wide Web to engineering the technology underlying life-saving magnetic resonance imaging (MRI) devices. But sometimes the raw power of huge experiments and scientific ambition draw the recognition of those seeking only the most extreme achievements on Earth.

(Phys.org) -- The world’s smallest three-dimensional optical cavities with the potential to generate the world’s most intense nanolaser beams have been created by a scientific team led by researchers with the DOE’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley.

Researchers found that overweight people burned 350 more calories a day, on average, when they ate a low-carbohydrate diet, than when they ate a low-fat diet.

Modern research tools like supercomputers, particle colliders, and telescopes are generating so much data, so quickly, many scientists fear that soon they will not be able to keep up with the deluge.

Just glancing at a photo of a rich and gooey chocolate cake can set your brain circuits sparking, switching on cravings and revving up your appetite, a new study shows.

Climate change and overharvesting have put a Himalayan fungus valued for its purported aphrodisiac qualities at risk of extinction. Known variously as yarsagumba, yarchagumba, yartsa gunba, yatsa gunbu and, more colloquially, “Himalayan Viagra,” the parasitic caterpillar fungus Cordyceps ( Ophiocordyceps sinensis ) grows on and kills Tibetan ghost moths during their larval phase underground

Apple introduced a number of improvements to its mobile and desktop operating systems as well as its MacBook Pro and Air computers Monday at the company’s annual Worldwide Developer’s Conference in San Francisco. The conference is primarily aimed at programmers who will develop software and apps that run on Apple’s products but also provides a glimpse of what’s in store for some of its most popular electronics in the near future
