Killer whales and other marine mammals likely hear sonar signals more than we've known. That's because commercially available sonar systems, which are designed to create signals beyond the range of hearing of such animals, also emit signals known to be with
Atmospheric sprites have been known for nearly a century, but their origins were a mystery. Now, a team of researchers has evidence that sprites form at plasma irregularities and may be useful in remote sensing of the lower ionosphere."We are trying to understand t
An international team of researchers has, for the first time, identified an avian influenza virus in a group of Adélie penguins from Antarctica. The virus, found to be unlike any other circulating avian flu, is described in a study published this week in mBi
Technology for protecting spaceships from laser fire is feasible today, University of Leicester students discovered. The only drawback, so far, is that you won’t be able to see a thing outside.In anticipation of Star Wars Day on 4 May, three fourth-year Physics st
Arizona Sate University scientists, together with collaborators from the Chinese Academy of Sciences in Shanghai, have published yesterday, in Nature Structural and Molecular Biology, a first of its kind atomic level look at the enzyme telomerase that may unlock the sec
Northwestern University researchers are the first to develop a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. The low-cost, environmentally friendly solar cell can be made easily using "bench" chemistry
The oldest sections of transform faults, such as the North Anatolian Fault Zone (NAFZ) and the San Andreas Fault, produce the largest earthquakes, putting important limits on the potential seismic hazard for less mature parts of fault zones, according to a new study to
Lichen planus can affect the face, the mouth, the hands and feet and practically any other skin surface of the body. It is difficult to treat and the cause is often mysterious. The lesions may continue for years or may periodically emerge – sometimes in different
In a first-of-its-kind study of how a super material some think could transform the electronics industry moves in water, researchers at the University of California, Riverside Bourns College of Engineering found graphene oxide nanoparticles are very mobil
A team of university scientists and a NASA colleague were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below 3.2 km (2 miles) of ice. "We found organic soil that has been frozen to the bottom of the ic
