Unlike birds,bats might use a different magnetic compass to navigate

Bats, the only mammals known to possess the real ability to fly, have fascinated zoologists for a long time with their long-distance migration. How do they find their way home from an altitude of kilometers above sea level, where their stunt of ultrasonic echolocation does not work？ Recent discoveries supported the theory that bats might be able to use magnetic clues to figure out their own position,just like what birds do. However, the latest results from a joint study by a group of researchers from the CAS, East China Normal University and University of Auckland reveal that bats apply an interesting strategy different from the one underlying birds＇ orientation technique, though they both are believed to derive information about their position from the subtle changes in the magnetic field of the Earth.

A New finding pushes back the history of flying mammals by 70 million years

Teaming up with their US coworkers, CAS paleontologists have discovered, in Ningcheng of northern China's Inner Mongolia, the nearly complete fossil remains of a mammal that glided among the trees at least 125 million years ago. Before the finding, the earliest confirmed record of gliding flight of a mammal dates to about 51million years ago.     

CAS scores progress in MIS development

A CAS initiative to upgrade its management information system (MIS) is making landmark progress. The first-phase development of the Academia Resource Planning (ARP), a major MIS project at the Academy, passed the acceptance check by a 17-strong panel of experts on 23 January 2007 in Beijing.

Underwater robots to safeguard Olympic Games in 2008

A small-sized autonomous underwater vehicle(AUV) independently developed and built by CAS researchers has been designated as an underwater guard for the forthcoming Olympic Game in 2008 in Beijing. It has recently been approved by the Olympic Sub-committee of Sailing to be a component of the "underwater safety alert system" of the competition.     

Construction of high magnetic field facilities approved

On 25 January, the National Development and Reform Commission gave the green light to a proposal to construct high magnetic field facilities for experimental use. The suggestion was jointly submitted by the Ministry of Education and CAS.
