A team including Carlos Jaramillo,... 阅读全文>> 日期:2016-04-20 Researchers at The University of Texas MD Anderson Cancer Center have announced a new method for detecting DNA mutations in a single cancer cell versus current technology that analyzes millions of cells which they believe could have important applic... 阅读全文>> 日期:2016-04-20 For hundreds of millions of years, Earths climate has remained on a fairly even keel, with some dramatic exceptions: Around 80 million years ago, the planets temperature plummeted, along with carbon dioxide levels in the atmosphere. The Earth eventu... 阅读全文>> 日期:2016-04-20 Cities have their own distinct microbial communities but these communities dont vary much between offices located in the same city, according to a new study. The work, published this week in mSystems, an open access journal from the American Society... 阅读全文>> 日期:2016-04-20 Sharks, skates, and rays are oddities among the fish: They have appendages growing out of the gill arch, a small cradle of bones that supports the gills. This anatomical peculiarity has led to the proposal that the paired limbs of humans, and before... 阅读全文>> 日期:2016-04-19 Memories formed in one part of the brain are replayed and transferred to a different area of the brain during rest, according to a new UCL study in rats. The finding suggests that replay of previous experiences during rest is important for memory co... 阅读全文>> 日期:2016-04-19 A new study by a multidisciplinary team of researchers from the Hebrew University of Jerusalem and Hadassah Medical Center shows that eating vegetables and fruits grown in soils irrigated with reclaimed wastewater exposes consumers to minute quantit... 阅读全文>> 日期:2016-04-19 For nearly a billion people around the world, cassava is a staple crop and a primary source of calories. The plant is easy to cultivate -- cuttings grow well on marginal land--and it is very tolerant of drought. For the U.S. Department of Energy, th... 阅读全文>> 日期:2016-04-19 Using animal tissue samples--store-bought pork loin and beef liver--researchers from the University of Illinois at Urbana-Champaign have demonstrated the possibility of real-time video-rate data transmission through tissue for in-body ultrasonic com... 阅读全文>> 日期:2016-04-19 Thirty years ago, the Chernobyl Nuclear Power Plant in Pripyat, Ukraine, became the site of the worlds largest nuclear accident. While humans are now scarce in the Chernobyl Exclusion Zone, continued studies--including a just-published camera study... 阅读全文>> 日期:2016-04-19 Dinosaurs were already in an evolutionary decline tens of millions of years before the meteorite impact that finally finished them off, new research has found. The findings provide a revolution in the understanding of dinosaur evolution. Palaeontolo... 阅读全文>> 日期:2016-04-09 Some cells are meant to live, and some are meant to die. The linker cell of Caenorhabditis elegans, a tiny worm that is a favored model organism for biologists, is among those destined for termination. This cell helps determine the shape of the gona... 阅读全文>> 日期:2016-04-09 University of Houston physicists report finding major theoretical flaws in the generally accepted understanding of how a superconductor traps and holds a magnetic field.
