14-01-15 New research shows that humans and other primates burn 50% fewer calories each day than other mammals. The study, published January 13 in the Proceedings of the National Academy of Sciences, suggests that these remarkably slow metabolisms explain wh...

13-12-24 Researchers have discovered a cause of aging in mammals that may be reversible. The essence of this finding is a series of molecular events that enable communication inside cells between the nucleus and mitochondria（线粒体） . As communication brea...

13-10-11 Scientists have a promising new approach to combating deadly human viruses thanks to an educated hunch（预感，肉峰） by University of California, Riverside microbiology professor Shou-Wei Ding, and his 20 years of research on plants, fruit flies, ne...

13-08-05 Baby birds have sleep patterns similar to baby mammals, and their sleep changes in the same way when growing up. This is what a team from the Max Planck Institute for Ornithology and the University of Lausanne found out working with barn owls in the...

13-07-25 A new study by the Wildlife Conservation Society and Snow Leopard Trust reveals a disturbing link between the cashmere（羊绒） trade and the decay of ecosystems that support some of the planet's most spectacular yet little-known large mammals. The s...

13-06-20 The ongoing global growth in the human population will inevitably crowd out（挤出，推开） mammals and birds and has the potential to threaten hundreds of species with extinction within 40 years, new research shows. Scientists at The Ohio State Unive...

13-06-16 Mammals possess the remarkable ability to regenerate a lost fingertip, including the nail, nerves and even bone. In humans, an amputated fingertip can sprout back in as little as two months, a phenomenon that has remained poorly understood until now...

13-06-16 Scientists at the University of Liverpool have shed new light on how diving mammals, such as the sperm whale, have evolved to survive for long periods underwater without breathing. The team identified a distinctive molecular signature of the oxygen-...

13-06-06 Some 40 million years before rock singer Jim Morrison's lyrics earned him the moniker（绰号，名字） the Lizard King, an actual king lizard roamed the hot tropical forests of Southeast Asia, competing with mammals for food and other resources. A team...

13-05-09 During the late Pleistocene, a remarkably diverse assemblage of large-bodied mammals inhabited the mammoth steppe, a cold and dry yet productive environment that extended from western Europe through northern Asia and across the Bering land bridge to...
