A technique using satellites to create twice-yearly elevation maps of US mountain glaciers provides new insight into thinning of glaciers in the lower 48 states.
A new study offers a rare glimpse into the genetics of a herpes simplex virus transmission event -- information that may prove useful in future development of therapeutics and vaccines. The study reveals nearly perfect genetic transmission of the virus from a father to his son and lays the foundation for future studies exploring the genetic diversity of this virus.
Coherent states of negative ion resonances in electron-molecule interaction are observed in experiments on e -- H2 and e -- D2 reactions. A forward-backward asymmetry is observed in the ejection of H- ions from H2 in this reaction, whereas the asymmetry in D- from D2 is weaker, but changes direction with electron energy. These results arise from attachment of a single electron to a molecule forming coherent superposition of odd and even parity states of negative ions.
Students, and people in general, can tend to overestimate their own abilities. But University of Utah research shows that students who overcome this tendency score better on final exams. The boost is strongest for students in the lower 25 percent of the class. By thinking about their thinking, a practice called metacognition, these students raised their final exam scores by 10 percent on average -- a full letter grade.
Rice University researchers employ microfluidic devices to show how and why dispersants are able to break up deposits of asphaltene that hinder the flow of crude oil in wellheads and pipelines.
A step closer to understanding quantum mechanics: Swansea University's physicists develop a new quantum simulation protocol.
Little is known about the structures of our genetic material, chromosomes, which consist of long strings that -- according to our experience -- should be likely to become knotted. However, up to now it has not been possible to study this experimentally. Researchers at Johannes Gutenberg University Mainz (JGU) in Germany have now found that chromosomes may indeed be knotted.
New oral anticoagulants (NOACs) represent direct-acting drugs functioning selectively for one specific clotting factor. Their clinical indications are the prophylaxis and treatment of deep venous thrombosis and pulmonary embolism, the prevention of atherothrombotic episodes of individuals with acute coronary syndromes and atrial fibrillation
Tokyo Medical and Dental University (TMDU) researchers revealed that RANKL expressed by osteocytes is essential for the bone remodeling during orthodontic tooth movement. This result can facilitate the development of novel therapeutic strategies in orthodontics.
Researchers have discovered a new way to produce high energy photon beams. The new method makes it possible to produce these gamma rays in a highly efficient way, compared with today's technique. The obtained energy is a billion times higher than the energy of photons in visible light. These high intensity gamma rays significantly exceed all known limits, and pave the way towards new fundamental studies.
