日期:2016-06-21 Earths magnetosphere, the region of space dominated by Earths magnetic field, protects our planet from the harsh battering of the solar wind. Like a protective shield, the magnetosphere absorbs and deflects plasma from the solar wind which originate... 阅读全文>> 日期:2016-06-21 Scientists are getting closer to directly observing how and why water is essential to life as we know it. A study in this weeks Proceedings of the National Academy of Sciences provides the strongest evidence yet that proteins--the large and complex... 阅读全文>> 日期:2016-06-21 A species of wasp that is a natural enemy of a wood-boring beetle that kills black locust trees has been rediscovered, more than 100 years after the last wasp of this species was found. The discovery is significant because the wood-boring beetle, kn... 阅读全文>> 日期:2016-06-21 Oceanic manta rays-often thought to take epic migrations-might actually be homebodies, according to a new study. A Scripps Institution of Oceanography at the University of California San Diego-led research team studied satellite-tracked manta rays t... 阅读全文>> 日期:2016-06-21 A new NOAA outlook shows that many coral reefs across around the world will likely be exposed to higher-than-normal sea temperatures for an unprecedented third year in a row, leading to increased bleaching - and with no signs of stopping. While the... 阅读全文>> 日期:2016-06-19 A Washington State University researcher has found that statin drugs can dramatically lower the risk of infections in stroke patients. Doug Weeks, an adjunct professor in the Elson S. Floyd College of Medicine and director of research at St. Lukes R... 阅读全文>> 日期:2016-06-19 Researchers at the Texas Analog Center of Excellence (TxACE) at UT Dallas are working to develop an affordable electronic nose that can be used in breath analysis for a wide range of health diagnosis. While devices that can conduct breath analysis u... 阅读全文>> 日期:2016-06-19 A simulation of the powerful jets generated by supermassive black holes at the centers of the largest galaxies explains why some burst forth as bright beacons visible across the universe, while others fall apart and never pierce the halo of the gala... 阅读全文>> 日期:2016-06-19 An international team of astronomers have found that there are far more planets of the hot Jupiter type than expected in a cluster of stars called Messier 67. This surprising result was obtained using a number of telescopes and instruments, among th... 阅读全文>> 日期:2016-06-18 Its estimated that there are around 1,600 Giant Pandas in the wild. There are 300 in zoos and breeding centres around the world. Its unsure how long Giant Pandas live in the wild. However Chinese scientists reported zoo pandas as old as 35. A wild p... 阅读全文>> 日期:2016-06-17 Love them or hate them, Crocs -- the rubber clogs that started out in 2002 as boater-floaters for Jimmy Buffett types in Florida but have now sold more than 300 million pairs in 90 countries are here to stay. 卡洛驰于2002年创建在佛罗里达,当时是为划... 阅读全文>> 日期:2016-06-17 The researchers have established that chickens - just like people - have colour constancy. For birds, this means that they, in different environments and under different lighting conditions, recognise the colour of, for instance, berries and can the... 阅读全文>> 日期:2016-06-17 Environmental scientists from the University of Stirling have found beech forests across western Europe are increasingly at risk from drought - with areas of southern England worst affected. In a new 1.4 million study, part-funded by NERC, researche... 阅读全文>> 日期:2016-06-16 Plant pollens vary in quality as food sources for bees, and pollen from the sunflower family (the family that includes dandelions, daisies, and thistles) is known to have some unpleasant qualities. Bees fed exclusively sunflower pollen often develop... 阅读全文>> 日期:2016-06-16 Cats understand the principle of cause and effect as well as some elements of physics. Combining these abilities with their keen sense of hearing, they can predict where possible prey hides. These are the findings of researchers from Kyoto Universit... 阅读全文>> 日期:2016-06-16 Researchers from the Universities of Bristol and Exeter are one step closer to developing a new generation of low-cost, high-efficiency solar cells. The structure is one of the worlds first examples of a tri-layer metasurface absorber using a carbon... 阅读全文>> 日期:2016-06-16 A pair of studies led by Indiana University researchers provide new evidence that when it comes to evolution, the testes may play a key role. The research, led by Kimberly Rosvall, assistant professor in the IU College of Arts and Sciences Departmen... 阅读全文>> 日期:2016-06-16 Like a pair of human hands, certain organic molecules have mirror-image versions of themselves, a chemical property known as chirality. These so-called handed molecules are essential for biology and have intriguingly been found in meteorites on Eart... 阅读全文>> 日期:2016-06-16 Gravitational waves from a second pair of colliding black holes has validated the landmark discovery from earlier this year that confirmed Einsteins general theory of relativity.
