NASA satellite sees developing tropical depression near Philippines

Tweet

System 91W appears ripe to become Tropical Depression 4 in the next couple of days as it continues moving north and parallels the east coast of the Philippines. NASA's Aqua satellite captured a visible image of the developing low pressure area as it passed overhead in space on June 17.

On June 16 at 2200 UTC (6 p.m. EDT) System 91W was located near 13.5N and 126.9E, about 355 miles east-southeast of Manila, Philippines.

Pyrocumulus cloud billows from New Mexico fire

On June 12, 2013, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this image of the Silver fire burning east of Silver City, New Mexico. In addition to producing gray smoke plumes, the fire spawned a pyrocumulus cloud—a tall, cauliflower-shaped cloud that billowed up above the smoke.

Is there an invisible tug-of-war behind bad hearts and power outages?

Tweet

Systems such as a beating heart or a power grid that depend on the synchronized movement of their parts could fall prey to an invisible and chaotic tug-of-war known as a "chimera." Sharing its name with the fire-breathing, zoologically patchy creature of Greek mythology, a chimera state arises among identical, rhythmically moving components — known as oscillators — when a few of those parts spontaneously fall out of sync while the rest remain synchronized.

Mice in a 'big brother' setup develop social structures

How does a social animal – mouse or human – gain dominance over his or her fellow creatures? A unique experiment conducted by Dr. Tali Kimchi and her team in the Weizmann Institute's Neurobiology Department provides some unusual insight into the social behavior that enables a social hierarchy, complete with a head honcho, to form.

Stop hyperventilating, say energy efficiency researchers

Tweet

RICHLAND, Wash. – A single advanced building control now in development could slash 18 percent – tens of thousands of dollars – off the overall annual energy bill of the average large office building, with no loss of comfort, according to a report by researchers at the Department of Energy's Pacific Northwest National Laboratory.

"An 18-percent boost in building energy efficiency by modifying a single factor is very, very good," said team leader Michael Brambley. "The savings were much greater than we expected."

Community-based programs may help prevent childhood obesity

Tweet

When it comes to confronting childhood obesity, researchers at the Johns Hopkins Bloomberg School of Public Health conclude that community-based approaches are important. A systematic review of childhood obesity prevention programs found that community-based intervention programs that incorporate schools and focus on both diet and physical activity are more effective at preventing obesity in children. The results of the study appear online in Pediatrics.

Short-term antidepressant use, stress, high-fat diet linked to long-term weight gain
