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 |Researchers at the University of Illinois have developed a technique for fabricating three-dimensional, single-crystalline silicon structures from thin films by coupling photolithography and a self-fo...
Physics and Astronomy |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 |A team of researchers at the Massachusetts Institute of Technology has developed a new modeling methodology for determining the capacity and assessing the risks of leakage of potential underground car...
Physics and Astronomy |These cells, known as circulating tumor cells, or CTCs, can provide critical information for examining and diagnosing cancer metastasis, determining patient prognosis, and monitoring the effectiveness...
Life Sciences |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 oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the ...
Earth Sciences |Comparing grasslands and pastureland in different regions in the U.S., the study, published in Global Change Biology, discusses data from more than 21,000 different fecal samples collected during a 14...
Life Sciences |Their findings were published online in the Journal of Physics: Condensed Matter. The article was selected for inclusion in the Institute of Physics’ IOP Select, which is a special collection of artic...
Physics and Astronomy |According to a recent report by the National Research Council of the National Academy of Sciences, the United States, once the world leader in the discovery and growth of crystalline materials, is now...
Materials Sciences |Or do they?No instant replays. On-screen statistics are confined to the JumboTron. Sharing excitement and opinions on the game is often limited to chatting with surrounding strangers.Y...
Communications Media |Two independent teams have, for the first time, created Bose-Einstein condensates of strontium atoms. The ability to cool strontium to very low temperatures and control its motion could lead to increa...
Physics and Astronomy |Physicists at Harvard University have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving in ...
Physics and Astronomy |“The Kenyan Rift volcanoes are part of a larger Great Rift Valley complex that extends all the way from Mozambique to Djibouti; their presence in East Africa attests to the presence of magma reservoir...
Earth Sciences |A new study compares neighborhoods' walkability (degree of ease for walking) with local levels of air pollution and finds that some neighborhoods might be good for walking, but have poor air qual...
