14-07-31 I believe in the 50-percent theory. Half the time things are better than normal; the other half, they are worse. I believe life is a pendulum swing（测锤摆幅） . It takes time and experience to understand what normal is, and that gives me the perspe...

13-01-25 The discovery of a new bird-like dinosaur from the Jurassic period challenges widely accepted theories on the origin of flight. Co-authored by Dr Gareth Dyke, Senior Lecturer in Vertebrate Palaeontology at the University of Southampton, the paper de...

12-12-17 While some theoretical physicists make predictions about astrophysics（天体物理学） and the behavior of stars and galaxies, others work in the realm of the very small, which includes quantum physics. Such is the case at UC Santa Barbara, where theor...

12-05-04 I believe in the 50-percent theory. Half the time things are better than normal; the other half, they are worse. I believe life is a pendulum（钟摆） swing. It takes time and experience to understand what normal is, and that gives me the perspective...

11-06-12 In recent years, UC Santa Barbara scientists showed that they could reproduce a basic superconductor（超导体） using Einstein's general theory of relativity. Now, using the same theory, they have demonstrated that the Josephson junction could be rep...

11-03-04 Fossil records verify a long-standing theory that horses evolved through natural selection, according to groundbreaking research by two anatomy（解剖学） professors at New York College of Osteopathic Medicine (NYCOM) of New York Institute of Technol...

10-05-28 Pre-humans living in East Africa 4.4 million years ago inhabited savannas（热带稀树草原） -- grassy plains dotted with（点缀，散布） trees and shrubs（灌木） -- according to a team of researchers that includes earth science Naomi Levin of The Johns...

10-05-14 Researchers at the Santa Fe Institute have developed new machine learning methods to study conflict. Their work appears in PLOS Computational Biology on May 13. Quantitative studies（定量研究） of behavior traditionally rely on game theory to invest...

10-03-29 The exceptionally simple theory of everything, proposed by a surfing physicist in 2007, does not hold water, says Emory University mathematician Skip Garibaldi. Garibaldi did the math to disprove（反驳） the theory, which involves a mysterious struc...
