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...
Studies and Analyses |Thirty years ago, theorists John Dawson and Toshiki Tajima proposed an idea for making them thousands of times smaller: surf the particles on plasma waves driven by short intense laser pulses. Since p...
Physics and Astronomy |The U.S. Environmental Protection Agency today announced a study that will investigate ways to reduce pollution that can run off paved surfaces and improve how water filters back into the ground....
Ecology, The Environment and Conservation |Now a team of chemical engineers at the University of Massachusetts Amherst has developed a computational model that shows that carbon nanotubes may offer a surprising solution. Results are presented ...
Power and Electrical Engineering |According to Duke University engineers, the answer is "jumping" water droplets. As it turns out, the same phenomenon that occurs when it's time for certain mushrooms to eject spores als...
