Science News highlights aerial gymnastics of fruit flies

Science News 12 April 2010
Fruit flies make abrupt turns

Postdoctoral research associate in engineering Attila Bergou is part of a research team that discovered that fruit flies’ aerial gymnastics are driven by wing joints that act like wind-up toys, letting the bugs whirl around almost automatically.

Science Nation profiles NSF collaborative project on bat flight mechanics

Brown University engineer Kenny Breuer and biologist Sharon Swartz are profiled in this week's Science Nation, a science video series commissioned by the NSF Office of Legislative and Public Affairs.
Since 2001, Swartz and Breuer have teamed up to study the mechanics of bat flight. With support from the National Science Foundation (NSF), the two scientists from very different disciplines set up a special facility, including a wind tunnel, to study bats in flight.

Gao and his research team discovers new principle in Material Science

A research team led by Brown University engineers has discovered a new mechanism that governs the peak strength of nanostructured metals. The team found that the deformation of nanotwinned metals is characterized by the motion of highly ordered, necklace-like patterns of crystal defects called dislocations. The finding, published in Nature, could lead to stronger and more ductile metals.

Yang and Taylor earn STAR awards from the Society for Biomaterials

Lei Yang (co-advised by Professors Tom Webster and Brian Sheldon) and Erik Taylor (advised by Professor Tom Webster) were just selected for STAR awards from the Society for Biomaterials. They will give their award winning talks during the Society for Biomaterials' Annual Meeting April 21st - 24th in Seattle, WA. This is one of the highest honors for graduate students presenting at the Society for Biomaterials. Erik was chosen based on his abstract and research "Decreasing Biofilm Formation Through the Use of Magnetic Nanoparticles". Lei was chosen based on his abstract and research "Osteoblast Responses on Nanocrystalline Diamond Modified by Hydrogen, Oxygen, and Ammonium Plasmas".

Collaborative project highlighted in premier neuroscience journal

The February issue of the journal Neuron features a cover story highlighting the joint work between Professors Arto Nurmikko and Barry Connors. Neuron is a premier journal in Neuroscience.

This is another illustration of the collaboration between Engineering and Biology and Medicine here at Brown. Arto Nurmikko's group has successfully led the initiative to bring the ‘optogenetics’ methodology to Brown.

Prof. Webster and Erik Taylor's implant research highlighted

PROVIDENCE, R.I. (Ivanhoe Newswire) -- Almost 1 million people go under the knife every year for a knee, hip or shoulder replacement. Surgeons say those metal implants can become playgrounds for bacteria, leading to potentially deadly infections like MRSA. It happens to nearly 20,000 people every year. One scientist has developed a tiny solution that could kill the infection without removing the implant.

Dr. Webster is creating a nano-sized solution to fight implant infections. He manufactured iron-oxide nanoparticles -- tiny warriors that zero in on the implant, penetrate the bacterial shield, and kill the bacteria. In lab tests, an injection of the specially-designed nanoparticles eliminated 74 percent of the bacteria on an implant in 48 hours. When repeated three times over six days, the nanoparticles killed 100  percent of the bacteria.
