AUSTIN, Texas — The three-dimensional structure of a site on an influenza B virus protein that suppresses human defenses to infection has been determined by researchers at Rutgers University and The University of Texas at Austin.
The discovery could help scientists develop drugs to fight seasonal influenza epidemics caused by the common influenza B strain.
Their discovery also helps explain how influenza B is limited to humans, and why it cannot be as virulent as A strains that incorporate new genes from influenza viruses that infect other species. (more…)
*Northeast China fossil provides new information about earliest ancestors of today’s mammals*
A well-preserved fossil discovered in northeast China provides new information about the earliest ancestors of most of today’s mammal species–the placental mammals. (more…)
PASADENA, Calif. – Scientists using data from NASA’s Wide-field Infrared Survey Explorer (WISE) have discovered the coldest class of star-like bodies, with temperatures as cool as the human body. (more…)
Reporting in Nature Materials this week, researchers from the London Centre for Nanotechnology and the Physics Department of Sapienza University of Rome have discovered a technique to ‘draw’ superconducting shapes using an X-ray beam. This ability to create and control tiny superconducting structures has implications for a completely new generation of electronic devices.
Superconductivity is a special state where a material conducts electricity with no resistance, meaning absolutely zero energy is wasted. (more…)
EAST LANSING, Mich. — Being able to count helps spotted hyenas decide to fight or flee, according to research at Michigan State University.
When animals fight, the larger group tends to win. In the current issue of Animal Behaviour, Sarah Benson-Amram, an MSU graduate student studying zoology, showed that hyenas listen to the sound of intruders’ voices to determine who has the advantage. (more…)
COLUMBUS, Ohio – Researchers who are working to fix global positioning system (GPS) errors have devised software to take a more accurate measurement of altitude – particularly in mountainous areas.(more…)
*Drought simulator will enable in-depth testing under real-world conditions*
COLUMBIA, Mo. – Historically, droughts have had devastating effects on agriculture, causing famine and increasing consumer food costs. Now, researchers at the University of Missouri College of Agriculture, Food and Natural Resources (CAFNR) have completed two drought simulators designed to test the effects of water deficiency on crops. The simulators are located at the University of Missouri’s Bradford Research and Extension Center east of Columbia.
The simulators, part of a $1.5 million Missouri Life Sciences Research Board grant, are essentially mobile greenhouses measuring 50 feet by 100 feet. To simulate drought, researchers move the greenhouses over plants when it is raining and move them away from plants when it is sunny. A test plot of the same plants will be kept next to the simulator to provide a comparison. The drought simulators will increase the real-world application of scientific research, as they allow researchers to more closely mimic actual drought conditions. (more…)
