Rice breakthrough could prevent multiple fibrotic diseases

   A scientific breakthrough at Rice University may lead to the first treatment that prevents the build-up of deadly scar tissue in a broad class of diseases that account for an estimated 45 percent of U.S. deaths each year. Fibrotic diseases include cardiac and pulmonary fibrosis, atherosclerosis, asthma, cirrhosis and scleroderma. Rice researchers have discovered a naturally occurring blood protein that's proven effective at preventing fibrotic scarring in lab animals.

Bats in flight reveal unexpected aerodynamics

   Brown University engineers and biologists have joined forces to record the fine details of wing and body movement in bat flight - together with the patterns of air movement that generate lift. Similar measurements have been made in insects and some birds, but this is the first such data for bats, which are highly flexible and maneuverable flyers and a potential model for engineered micro air vehicles.

Tracing the pathways of neurofibromatosis

   New research into the mechanisms of neurofibromatosis finds that flaws in the gene Nf1 can lead to a biochemical domino effect that results in tumors. The research, which appears in the January 10 issue of the Journal of Neuroscience, seeks to identify the biochemical pathway responsible for tumors in people with the genetic disorder. Researchers built their case based on evidence from dozens of painstaking experiments on genetically engineered fruit flies.

Brain cleaner

   Brain injury causes glutamate, a substance necessary for proper brain function, to flood areas surrounding the trauma and kill other cells. Weizmann Institute scientists have developed a new way to rid the brain of excess glutamate. This method -- which uses an enzyme found in blood -- could lead to new therapies not only for brain injury, but also for stroke and other conditions, and holds promise for prevention of damage from meningitis or nerve gas.

Cosmic radiation, which contains the terahertz frequencies that the sensors detect, offers astronomers important new information about the birth of star systems and planets. Merlijn Hajenius developed these sensors for Delft University of Technology's Kavli Institute of Nanoscience, in cooperation with the SRON Netherlands Institute for Space Research. He will receive his PhD degree on 19 January based on this research subject.
