Chilling methods could change meat tenderness

In a recent paper published in the Journal of Animal Science, meat scientists report that a method called blast chilling could affect pork tenderness. Researchers at the USDA-ARS, Roman L. Hruska US Meat Animal Research Center ...

Solar storms can destabilize power grids at midlatitudes

The Sun is capable of disrupting electrical systems on Earth in a variety of ways, from solar flares and coronal mass ejections to proton storms. Typically, it is only objects far above the Earth's surface, or systems at ...

Wetlands the primary source of Amazon Basin methane

The Amazon basin is an important sink of carbon dioxide, but it is also a substantial source of atmospheric methane. Tropical wetlands, including those in the Amazon, are one of the largest sources of biogenic methane and ...

Old fractures caused rare 8.6 magnitude earthquake

On 11 April 2012, an 8.6 magnitude earthquake occurred 100 kilometers (62 miles) off the coast of Sumatra. This earthquake was unusual in that it originated within the plate rather than at a plate boundary. In fact, it is ...

Rutgers team has ring prototype for touch authentication

(Phys.org)—What about using the same mobile device touchscreens used every day for direct authentication? What if your touch alone identifies you by code from the ring on your finger? A team from the WINLAB at Rutgers ...

The Everglades still threatened by excess nutrients

Since 1985, a state agency has constructed and continues to maintain hundreds of square kilometers of wetlands built to regulate the amount of nutrients reaching the Everglades in southern Florida. But this is proving to ...

Low calcification in corals in the Great Barrier Reef

Reef-building coral communities in the Great Barrier Reef-the world's largest coral reef-may now be calcifying at only about half the rate that they did during the 1970s, although live coral cover may not have changed over ...

NASA to launch smartphone-operated nanosatellites

NASA is relying on a small team of engineers at its Ames Research Center at California's Moffett Field to develop three nanosatellites operated by smartphones.

A millimeter-scale, wirelessly powered cardiac device

A team of engineers at Stanford has demonstrated the feasibility of a super-small, implantable cardiac device that gets its power not from batteries, but from radio waves transmitted from outside the body. The implanted device ...
