Engineers searched online for equations more frequently in 2013, but were dissatisfied with results

February 10, 2014 4:58 pm | News | Comments

Engineers conduct more searches for equations online, but they are dissatisfied with the results, a 2013 survey conducted on behalf of Knovel found. A majority of engineers surveyed look for equations at least once a week, and increasingly they search via the Internet first, rather than references, handbooks and other sources.

Shape-sifting: NIST categorizes bio scaffolds by characteristic cell shapes

February 10, 2014 4:27 pm | by EurekAlert! | News | Comments

Getting in the right shape might be just as important in a biology lab as a gym. Shape is thought to play an important role in the effectiveness of cells grown to repair or replace damaged tissue in the body. To help design new structures that enable cells to "shape up," researchers at the National Institute of Standards and Technology (NIST) have come up with a way to measure....

Rugged, rapid monitor safeguards space crews

February 10, 2014 4:23 pm | by EurekAlert! | News | Comments

There are few things as important on, and especially off, Earth as breathable, quality air. When air quality is compromised, we often don't have seconds to spare, which is why development of the Multi-Gas Monitor is so important. This shoebox-sized, battery-powered monitor can measure the concentrations of multiple gases....

Genome editing goes hi-fi

February 10, 2014 4:19 pm | by EurekAlert! | News | Comments

Sometimes biology is cruel. Sometimes simply a one-letter change in the human genetic code is the difference between health and a deadly disease. But even though doctors and scientists have long studied disorders caused by these tiny changes, replicating them to study in human stem cells....

Optogenetic toolkit goes multicolor

February 10, 2014 4:14 pm | by EurekAlert! | News | Comments

Optogenetics is a technique that allows scientists to control neurons' electrical activity with light by engineering them to express light-sensitive proteins. Within the past decade, it has become a very powerful tool for discovering the functions of different types of cells in the brain.

Cochlear implants -- with no exterior hardware

February 10, 2014 4:12 pm | by EurekAlert! | News | Comments

Cochlear implants — medical devices that electrically stimulate the auditory nerve — have granted at least limited hearing to hundreds of thousands of people worldwide who otherwise would be totally deaf. Existing versions of the device, however, require that a disk-shaped transmitter about an inch in diameter be affixed to the skull....
