Bacteria Use Hydrogen, Carbon Dioxide to Produce Electricity
May 19, 2013 — Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of ... > full story -
Origins of Life: In Early Earth, Iron Helped RNA Catalyze Electron Transfer
May 19, 2013 — A new study shows how complex biochemical transformations may have been possible under conditions that existed when life began on the early Earth. The study shows that RNA is capable of catalyzing ... > full story -
Genome Sequence of Tibetan Antelope Sheds New Light on High-Altitude Adaptation
May 17, 2013 — How can the Tibetan antelope live at elevations of 4,000-5,000m on the Qinghai-Tibetan Plateau? Investigators now provide evidence of genetic factors that may be associated with the species' adaption ... > full story -
Add Boron for Better Batteries
May 16, 2013 — A graphene-boron compound is theoretically capable of storing double the energy of common graphite anodes used in lithium-ion ... > full story -
Target to Prevent Hardening of Arteries Identified
May 16, 2013 — The gene Dkk1 encodes a protein that plays a key role in increasing the population of connective-tissue cells during wound repair, but prolonged Dkk1 signaling in cells lining blood vessels can lead ... > full story -
Gene Involved in Neurodegeneration Keeps Clock Running: Scientists Identify Another Gene Important to Morning Wake-Up Call
May 16, 2013 — Scientists have shown a gene involved in neurodegenerative disease also plays a critical role in the proper function of the circadian clock. In a study of the common fruit fly, the researchers found ... > full story -
Artificial Forest for Solar Water-Splitting: First Fully Integrated Artificial Photosynthesis Nanosystem
May 16, 2013 — Researchers have created the first fully integrated artificial photosynthesis nanosystem. While "artificial leaf" is the popular term for such a system, the key to this success was an "artificial ... > full story -
Accelerated Aging in Children: Promising Treatment for Progeria Within Reach
May 16, 2013 — Pharmaceuticals that inhibit a specific enzyme may be useful in treating progeria, or accelerated aging in children. A new study indicates that the development of progeria in mice was inhibited upon ... > full story -
Beautiful 'Flowers' Self-Assemble in a Beaker
May 16, 2013 — With the hand of nature trained on a beaker of chemical fluid, the most delicate flower structures have been formed in a laboratory -- and not at the scale of inches, but microns. These minuscule ... > full story -
DNA-Guided Assembly Yields Novel Ribbon-Like Nanostructures
May 16, 2013 — DNA "linker" strands coax nano-sized rods to line up in way unlike any other spontaneous arrangement of rod-shaped objects. The arrangement -- with the rods forming "rungs" on ladder-like ribbons -- ... > full story
