Video game technology aids horse rider assessment

Posted: 09 Jun 2014 07:28 AM PDT

Horse riders' balance, symmetry and poor posture could be improved thanks to an innovative body suit that works with motion sensors, commonly used by movie makers and the video games industry. New research uses inertial motion sensors worn in the XsensTM MVN body suit, and is now showing promising results as a method of assessing rider asymmetry and lower back pain and injury risk.

Beer brewing waste could help bone regeneration

Posted: 09 Jun 2014 06:38 AM PDT

Biomaterials for bone regeneration have been developed by researchers from beer brewing waste. The waste obtained from the beer brewing process contains the main chemical components found in bones (phosphorus, calcium, magnesium and silica), that after undergoing modification processes, this waste can be used as support or scaffold to promote bone regeneration for medical applications such as coating prosthesis or bone grafts, researchers report.

Facing a violent past: Evolution of human ancestors' faces a result of need to weather punches during arguments, study suggests

Posted: 09 Jun 2014 06:36 AM PDT

An alternative to the previous long-held hypothesis that the evolution of the robust faces of our early ancestors resulted largely from the need to chew hard-to-crush foods such as nuts has been presented by researchers. The prehistoric version of a bar fight -- over women, resources and other slug-worthy disagreements -- are what shaped our facial evolution, new research suggests.

I shouldn't have eaten there: Rats show behavior of 'regret' in choosing the wrong 'restaurant'

Posted: 08 Jun 2014 12:27 PM PDT

New research reveals that rats show signs of 'regret' -- a cognitive behavior once thought to be uniquely and fundamentally human. To measure the cognitive behavior of regret, scientists developed a task that asked rats how long they were willing to wait for certain foods. In this task, the rats are presented with a series of food options but have limited time at each 'restaurant.'

Fruit flies: Brain traffic jams that can disappear in 30 seconds

Motorists in Los Angeles, San Francisco and other gridlocked cities could learn something from the fruit fly. Scientists have found that cellular blockages, the molecular equivalent to traffic jams, in nerve cells of the insect's brain can form and dissolve in 30 seconds or less.

Unique way that catfish locate prey: 'Whiskers' detect slight changes in pH

Posted: 05 Jun 2014 03:36 PM PDT

Catfish are equipped with sensors that can locate prey by detecting slight changes in the water's pH level, researchers have discovered. The study was an offshoot of work initiated in 1984 when researchers began a collaborative investigation examining the physiology of the taste system of the Japanese sea catfish. While performing electrical recordings from the fish barbells, or "whiskers," he noticed that every so often some new sensory nerve fibers would respond at a much larger amplitude than the others.

Students' heart-shocking 'shirt' may save lives when paramedics are not nearby

Posted: 04 Jun 2014 05:28 PM PDT

A lightweight, easy-to-conceal shirt-like garment to deliver life-saving shocks to patients experiencing serious heart problems has been designed by biomedical engineering students. The students say their design improves upon a wearable defibrillator system that is already in use.
