Protein shake-up

March 26, 2015 10:47 am | by Chris Samoray, Oak Ridge National Laboratory | News | Comments

For living organisms proteins are an essential part of their body system and are needed to thrive. In recent years, a certain class of proteins has challenged researchers’ conventional notion that proteins have a static and well-defined structure. It’s thought that mutations in these proteins, known as intrinsically disordered proteins, are associated with neurodegenerative changes, cardiovascular disorders and diseases like cancer.

Snake robots learn to turn by following real sidewinders’ lead

March 25, 2015 7:59 am | by John Toon, Georgia Institute of Technology | News | Comments

Researchers at Carnegie Mellon Univ. (CMU) who develop snake-like robots have picked up a few tricks from real sidewinder rattlesnakes on how to make rapid and even sharp turns with their undulating, modular device. Working with colleagues at the Georgia Institute of Technology and Zoo Atlanta, they have analyzed the motions of sidewinders and tested their observations on CMU’s snake robots.

“Virtual nose” may reduce simulator sickness in video games

March 25, 2015 7:50 am | by Emil Venere, Purdue Univ. | News | Comments

Virtual reality games often cause simulator sickness, but new research findings point to a potential strategy to ease the affliction. Various physiological systems govern the onset of simulator sickness: a person's overall sense of touch and position, or the somatosensory system; liquid-filled tubes in the ear called the vestibular system; and the oculumotor system, or muscles that control eye movements.
