On August 1, 2008 a total solar eclipse was visible within a narrow corridor that traversed from North America to China.
New research published this week clips the wings of Archaeopteryx. First found in Germany in the 1860's and dating to 150 million years ago, Archaeopteryx has long been considered the iconic first bird.
RICHMOND, Va. (Sept. 1, 2009) -- An international team of researchers has designed a new graphite-based, magnetic nano-material that acts as a semiconductor and could help material scientists create the next generation of electronic devices like microchips.
Nanochemists from the Chinese Academy of Sciences and Nano-Science Center, Department of Chemistry at University of Copenhagen have developed nanoscale electric contacts out of organic and inorganic nanowires. In the contact they have crossed the wires like Mikado sticks and coupled several contacts together in an electric circuit.
Stem cell research promises remedies to many devastating diseases that are currently incurable, ranging from diabetes and Parkinson's disease to paralysis. Totipotent embryonic stem cells have great potential for generating a wide range of different human cells that can be used to restore malfunctioning or damaged cells and tissues in patients.
When the magnitude 8 Sichuan earthquake struck southern China in May 2008, it left more than 69,000 people dead and 4.3 million homeless. Now ecologists have added to these losses an assessment of the earthquake's impact on biodiversity: namely, habitat for some of the last existing wild giant pandas.
Scientists have discovered a unique beaked, plant-eating dinosaur in China. The finding, they say, demonstrates that theropod, or bird-footed, dinosaurs were more ecologically diverse in the Jurassic period than previously thought, and offers important evidence about how the three-fingered hand of birds evolved from the hand of dinosaurs.
James Clark, The George Washington University’s Ronald B. Weintraub Professor of Biology, and Xu Xing, of the Chinese Academy of Science’s Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, have discovered a unique beaked, plant-eating dinosaur in China.
Plants or meat: That's about all that fossils ever tell paleontologists about a dinosaur's diet. But the skull characteristics of a new species of parrot-beaked dinosaur and its associated gizzard stones indicate that the animal fed on nuts and/or seeds. These characteristics present the first solid evidence of nut-eating in any dinosaur.

Scientists have identified for the first time a mechanism by which nanoparticles
cause lung damage and have demonstrated that it can be combated by blocking the
process involved, taking a step toward addressing the growing concerns over the
safety of nanotechnology.
DALLAS -- June 8, 2009 -- The fuzzy pale mold that lines the glass tubes in Dr. Yi Liu's lab doesn't look much like a clock.
But this fungus has an internal, cell-based timekeeper nearly as sophisticated as a human's, allowing UT Southwestern Medical Center physiologists to study easily the biochemistry and genetics of body clocks, or circadian rhythms.

In collaboration with the Chinese Academy of Sciences in Beijing, scientists have investigated the rotation of molecules on a fixed surface to understand how they may help in the development of future rotor-based machinery at nanoscale level.
The latest special issue of Science in China Series C: Life Sciences focuses on the recent progress in the H5N1-related research field.
