Researchers found that the response of atmospheric circulation to sea-ice loss was stronger than that to snow melt. Accompanying the vanishing cryosphere is a changing jet stream: weakened west-to-east winds and a general northward shift. Consequently, the atmospheric circulation change tends to favor more persistent weather systems and a higher likelihood of summer weather extremes.
Tetrahymena thermophila is a species of free-living unicellular ciliated protozoa that is widely distributed in freshwater environments around the world. CAS researchers recently provided the first global survey of phosphorylation in T. thermophila using a phosphoproteomic approach and suggest a wide ranging regulatory scope of this modification. The integrated analysis of phosphoproteomics data with transcripteomics data provide a point of departure for more in-depth studies in understanding the physiological functions underlying phosphorylation and facilitate the elucidation of the entire signaling networks in the specific context of T. thermophila.
Chinese scientists said great progress has been made in quality control technologies and standardization of traditional Tibetan medicine after 20 years of research. A total of 264 criteria for Tibetan medicine processing have been completed since the "key technologies and applications in Tibetan medicine quality control" program was launched in 1993, said Wei Lixin, one of the project's researchers.
China's Chang'e-3 probe entered a circular lunar orbit at 5:53 pm Friday Beijing Time, after about 112 hours on a Earth-Moon transfer orbit, the Beijing Aerospace Control Center (BACC) said. The probe entered the lunar orbit after 361 seconds of precise braking by the variable thrust engine, following orders by engineers with BACC.
Another ancient genome, another mystery. DNA gleaned from a 400,000-year-old femur from Spain has revealed an unexpected link between Europe’s hominin inhabitants of the time and a cryptic population, the Denisovans, who are known to have lived much more recently in southwestern Siberia. The DNA, which represents the oldest hominin sequence yet published, has left researchers baffled because most of them believed that the bones would be more closely linked to Neanderthals than to Denisovans.
China's lunar probe Chang'e-3 has entered the earth-moon transfer orbit after it separated from the carrier rocket, space authorities announced Monday. Chang'e-3 arrived at the orbit with a perigee of 200 kilometers and an apogee of 380,000 kilometers as scheduled. The lunar probe, including a lander and a moon rover, is expected to soft-land on the moon in mid-December if everything goes according to plan.
