12-11-01 Stanford University scientists have built the first solar cell made entirely of carbon, a promising alternative to the expensive materials used in photovoltaic（光电的） devices today. The results are published in the Oct. 31 online edition of the j...

12-10-09 Scientists at the Gladstone Institutes have mapped the precise frequency by which genes get turned on across the human genome, providing new insight into the most fundamental of cellular processes -- and revealing new clues as to what happens when t...

12-07-23 UCLA researchers have developed a new transparent solar cell that is an advance toward giving windows in homes and other buildings the ability to generate electricity while still allowing people to see outside. Their study appears in the journal ACS...

12-07-23 Only by viewing a Seurat painting at close range can you appreciate the hidden complexities of pointillism（点描绘法） -- small, distinct dots of pure color applied in patterns to form an image from a distance. Similarly, biologists and geneticists...

12-06-26 How single cell organisms like bacteria manage to react to their environment is not yet completely understood. Together with colleagues from Japan, Dr. Samir El-Mashtoly from the RUB Department of Biophysics, led by Prof. Dr. Klaus Gerwert, has gain...

12-06-08 In exploring the genetics of mitochondria（线粒体） -- the powerhouse of the cell -- researchers at Fred Hutchinson Cancer Research Center have stumbled upon a finding that challenges previously held beliefs about the role of mutations in cancer dev...

12-06-01 During formation of multi-cellular organisms, cells need to talk to each other to make critical decisions as to what kind of cell to become, as well as when and where to become that cell type. The Notch signaling system allows cells to directly talk...

12-04-05 A dose of carbon nanotubes more than doubles the growth rate of plant cell cultures（细胞培养） -- workhorses in the production of everything from lifesaving medications to sweeteners to dyes and perfumes -- researchers are reporting. Their study, t...

12-03-02 What if bacteria could talk to each other? What if they had a sense of touch? A new study by researchers at UC Santa Barbara suggests both, and theorizes that such cells may, in fact, need to communicate in order to perform certain functions. The fi...

12-03-02 In a paper just published in the journal Cell, a team from the University of North Carolina at Chapel Hill has explained for the first time how a long-studied protein complex affects cell migration and how external cues affect cell's ability to migr...
