Designing flexible and stretchable single crystal electronic systems
- ScienceDaily
- 20/5/13 23:11
Researchers at the University of Illinois at Urbana-Champaign in collaboration with a Purdue team have discovered that certain crystals are more flexible and stretchable compared to current materials used for electronic applications. These new materials could therefore be used for making sensors and in robotics.

- 20/5/13 20:38
A recent six-year study, the longest study ever done on video game addiction, found that about 90% of gamers do not play in a way that is harmful or causes negative long-term consequences. A significant minority, though, can become truly addicted to video games and as a result can suffer mentally, socially and behaviorally.

Microscopic feather features reveal fossil birds' colors and explain why cassowaries shine
- ScienceDaily
- 20/5/13 20:34
Some birds are iridescent because of the physical make-up of their feathers, but scientists had never found evidence of this structural color in the group of birds containing ostriches and cassowaries -- until now. Researchers have discovered both what gives cassowary feathers their glossy black shine and what the feathers of birds that lived 52 million years ago looked like.
A new, highly sensitive chemical sensor uses protein nanowires
- ScienceDaily
- 20/5/13 20:34
Scientists report that they have developed bioelectronic ammonia gas sensors that are among the most sensitive ever made. It uses electric-charge-conducting protein nanowires derived from the bacterium Geobacter to provide biomaterials for electrical devices. They grow hair-like protein filaments that work as nanoscale ''wires'' to transfer charges for their nourishment and to communicate with...
T. rex was a champion walker, highly efficient at lower speeds
- ScienceDaily
- 20/5/13 20:33
A new study suggests that long legs evolved among the biggest dinosaurs to help them conserve energy as they ambled along searching for prey, rather than for speed as previously assumed.
3D VR blood flow to improve cardiovascular care
- ScienceDaily
- 20/5/13 19:55
Biomedical engineers are developing a massive fluid dynamics simulator that can model blood flow through the full human arterial system at subcellular resolution. One of the goals of the effort is to provide doctors with a virtual reality system that can guide their treatment plans by allowing them to simulate a patient's specific vasculature and accurately predict how decisions such as stent...
New comet discovered by solar observatory
- ScienceDaily
- 20/5/13 19:55
In late May and early June, Earthlings may be able to glimpse Comet SWAN. The comet is currently faintly visible to the unaided eye in the Southern Hemisphere just before sunrise. The new comet was first spotted in April 2020, by an amateur astronomer named Michael Mattiazzo using data from the SOHO satellite.
