Latest and Breaking Chemistry & Physics News

Liquid crystal bubble OASIS in space
(NASA/Johnson Space Center) In the Observation and Analysis of Smectic Islands In Space (OASIS) study, scientists are using bubbles and the International Space Station to understand fluid dynamics and liquid crystal physics.

Mechanical engineering professor chosen as Fulbright scholar
(University of California - Santa Barbara) Valentine aims to strengthen research ties between UCSB and ESPCI ParisTech.

ORNL scientists generate landmark DOE hydropower report
(DOE/Oak Ridge National Laboratory) For the first time, industry and policymakers have a comprehensive report detailing the US hydropower fleet's 2,198 plants that provide about 7 percent of the nation's electricity.

Tidal tugs on Teflon faults drive slow-slipping earthquakes
(University of Washington) Teasing out how slow, silent earthquakes respond to tidal forces lets researchers calculate the friction inside the fault, which could help understand when and how the more hazardous earthquakes occur.

Ocean bacteria get 'pumped up'
(Woods Hole Oceanographic Institution) Scientists at Woods Hole Oceanographic Institution and their Rutgers University colleague discovered a surprising new short-circuit to the biological pump. They found that sinking particles of stressed and dying phytoplankton release chemicals that have a steroid-like effect on marine bacteria feeding on the particles. The chemicals juice up the bacteria's metabolism causing them to more rapidly convert organic carbon in the particles back into CO2 before they can sink to the deep ocean.

Strange supernova is 'missing link' in gamma-ray burst connection
(National Radio Astronomy Observatory) Astronomers find that 'central engines' in supernova explosions can come in different strengths, and include those that produce powerful blasts of gamma rays, and weaker versions that produce no such bursts.

Astrophysicists draw most comprehensive map of the universe
(University of Waterloo) Astrophysicists have created a 3-D map of the universe that spans nearly two billion light years and is the most complete picture of our cosmic neighborhood to date.

Lightweight membrane can significantly reduce in-flight aircraft noise
(North Carolina State University) Riding in a helicopter or airplane can be a noisy experience for passengers. But researchers have developed a membrane that can be incorporated into aircraft to drastically reduce the low-frequency noise that penetrates the cabin.

Finding the body clock's molecular reset button
(McGill University) An international team of scientists has discovered what amounts to a molecular reset button for our internal body clock. Their findings reveal a potential target to treat a range of disorders, from sleep disturbances to other behavioral, cognitive, and metabolic abnormalities, commonly associated with jet lag, shift work and exposure to light at night, as well as with neuropsychiatric conditions such as depression and autism.

Self-assembling biomaterial forms nanostructure templates for human tissue formation
(Mary Ann Liebert, Inc./Genetic Engineering News) Unlike scaffold-based methods to engineer human tissues for regenerative medicine applications, an innovative synthetic material with the ability to self-assemble into nanostructures to support tissue growth and ultimately degrade offers a promising new approach to deliver cell and tissue therapies. The unique properties of this biofunctional coating that enable it to stimulate and direct the formation of complex tissues are described in an article in Tissue Engineering, Part A.
