Dr Loretta Dunne and her team have found new evidence of huge dust production in the Cassiopeia A supernova remnant, the remains of a star that exploded about 300 years ago. The paper is set to be pub...
Physics and Astronomy |Metal alloys are solids made from at least two different metallic elements. The elements are often mixed together as liquid, and when they "freeze," into solids, tiny grains of crystal form ...
Materials Sciences |Being a nocturnal animal, it hunts predominantly with its sense of touch. Professor Michael Brecht (Bernstein Center for Computional Neuroscience, Berlin) now reported on the particularities of its hu...
Life Sciences |Three million people left their farms on the Great Plains during the drought and half a million migrated to other states, almost all to the West. But the Dust Bowl drought was not meteorologically ext...
Earth Sciences |Type1a supernovae are among the brightest objects in the universe. Astronomers use them as “standard candles” to gauge cosmological distances: brighter-appearing supernovae are closer, dimmer ones are...
Physics and Astronomy |Shrews are tiny mammals that have been widely characterized as simple and primitive. This traditional view is challenged by a new study of the hunting methods of an aquatic member of the species, the ...
Studies and Analyses |The gaol of the project is to develop machines with sophisticated touch technology, like robots that can use their whiskers like a rat to explore their surroundings. The 7.3 million Euro project will ...
Information Technology |When the Stardust mission returned to Earth with samples from the comet Wild 2 in 2006, scientists knew the material would provide new clues about the formation of our solar system, but they didn’t kn...
Physics and Astronomy |Make way for the real nanopod and make room in the Guinness World Records. A team of researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Unive...
Physics and Astronomy |That’s the method outlined in a paper published online August 12 by Nature Medicine. Scientists from the University of Rochester Medical Center show how the body’s natural way of ridding the body of t...
Health and Medicine |A team of scientists from WWF and Conservation International (CI) has discovered the world’s largest known population of grey-shanked doucs (Pygathrix cinerea), increasing chances that the Endangered ...
Ecology, The Environment and Conservation |A study of 209 families with at least two siblings with Alzheimer's and one unaffected sibling showed that those with this genetic variation are less likely to have the disease, researchers say i...
Life Sciences |Two Northwestern University engineers have been studying the whisker system of rats to better understand how mechanical information from the whiskers gets transmitted to the brain and to develop artif...
Information Technology |For these and other reasons, many sturgeons — a variety of ancient, bottom-feeding fish — are in trouble. Trent Sutton, a fisheries biologist at Purdue University, has helped to ensure that a ...
Ecology, The Environment and Conservation |University of Utah scientists have shown how evolution works by reversing the process, reconstructing a 530-million-year-old gene by combining key portions of two modern mouse genes that descended fro...
