The formation process involved two stages, said Mitchell Begelman, a professor and the chair of CU-Boulder's astrophysical and planetary sciences department. The predecessors to black hole format...
Physics and Astronomy |“It looks unlikely that there will be any substantial near-term departure from recently observed acceleration in carbon dioxide emission rates,” says the new paper by Tim Garrett, an associate profess...
Earth Sciences |The discovery paves the way for an entirely new way to approach the hydrogen-storage problem. The researchers found that the normally unreactive, noble gas xenon combines with molecular hydrogen (H2) ...
Life Sciences |Now, a team of Ohio and Michigan scientists have determined new routes by which 4-HB is metabolized by the body. “This is new and important information,” said K. Michael Gibson, professor and chair of...
Life Sciences |“Tsunamis can neither be prevented nor precisely predicted yet,” says site initiator Dr. Jian Lin, a WHOI geologist actively involved in tsunami research and a member of a U.S. national committee on t...
Earth Sciences |Physicians currently insert camera-equipped endoscopes into patients to hunt visible abnormalities, such as tumors, in the gastrointestinal tract and internal organs. Huikai Xie, an associate professo...
Medical Engineering |For the first time, scientists have successfully used a method called exome sequencing to quickly discover a previously unknown gene responsible for a mendelian disorder. Mendelian disorders, ...
Life Sciences |Now, physicists at the Joint Quantum Institute (JQI), a collaborative organization of the National Institute of Standards and Technology (NIST) and the University of Maryland, have developed a promisi...
Physics and Astronomy |NASA's QuikScat satellite uses microwave technology to peer through a tropical cyclone's clouds, and actually read the speed of the rotating surface winds. In an overpass from space at 7:58 ...
Earth Sciences |With thousands of stinging cells that can emit deadly venom from tentacles that can reach ten feet in length, the 50 or so species of box jellyfish have long been of interest to scientists and to the ...
Life Sciences |The technology could have applications in the design of micro-electromechanical systems (MEMS) – nanoscale devices with moving parts – and micro-optomechanical systems (MOMS) which combine moving part...
Physics and Astronomy |The study, which was led by Dr. Chen, is reported in Issue 52 of Science in China (G) because of its significant research value.Many explosive phenomena on the Sun, such as solar flares, invol...
Physics and Astronomy |Using ESO’s Very Large Telescope and its ability to obtain images as sharp as if taken from space, astronomers have made the first time-lapse movie of a rather unusual shell ejected by a “vampire star...
Physics and Astronomy |The sensor, incorporated in optical computer mice, is usually used to guide cursor movement, but can also be used as a counterfeit coin detector. This has been demonstrated by a prototype developed by...
Power and Electrical Engineering |Purdue University and NASA examined more than a dozen chemicals, most of which are generated by humans, and have developed a blueprint for the underlying molecular machinery of global warming. The res...
