The new method is based on the natural repair mechanism of plants. So-called homologous recombination repairs the genome when the genome strands in the cell break.
As the Earth's climate warms, a melting ice sheet produces a distinct and highly non-uniform pattern of sea-level change, with sea level falling close to the melting ice sheet and rising progressively farther away. The pattern for each ice sheet is unique and is known as its sea level fingerprint. N...
Detailed studies of one of the best-performing organic photovoltaic materials reveal an unusual bilayer lamellar structure that may help explain the material's superior performance at converting sunlight to electricity and guide the synthesis of new materials with even better properties.
Scientists at the U.S. Department of Energy's Ames Laboratory have designed a method to evaluate different conductors for use in metamaterial structures, which are engineered to exhibit properties not possible in natural materials. The work was reported this month in Nature Photonics.
Facebook will pay Microsoft Corp $550 million for hundreds of patents that originated with AOL, beefing up its intellectual property arsenal.
Every thought, every movement, every heartbeat is controlled by lightning-quick electrical impulses in the brain, the muscles, and the heart. But too much electrical excitability in the membranes of the cells can cause things like epilepsy and cardiac arrhythmia. A research group at Linköping Uni...
Humans that populated the banks of the river Manzanares (Madrid, Spain) during the Middle Palaeolithic (between 127,000 and 40,000 years ago) fed themselves on pachyderm meat and bone marrow. This is what a Spanish study shows and has found percussion and cut marks on elephant remains in the site of...
They laid eggs, occupied many ecological niches with only one species and competed with one another. Researchers from the University of Zurich have uncovered the chain of events that led to the extinction of the dinosaurs.
For 300 million years, they were the ultimate survivors. They successfully negotiated three mass extinctions, only to die out eventually at the end of the Cretaceous along with the dinosaurs:
A family history of liver cancer is reported to increase risk of developing hepatocellular carcinomas (HCC), independent of hepatitis according to findings published in the May issue of Hepatology, a journal of the American Association for the Study of Liver Diseases. The study also shows 70-fold el...
Around 450 million years ago, shallow seas covered the Cincinnati region and harbored one very large and now very mysterious organism. Despite its size, no one has ever found a fossil of this "monster" until its discovery by an amateur paleontologist last year.
Google Inc is preparing to roll out a service to let consumers store photos and other content online, a source familiar with the matter said, pushing into a market now dominated by the likes of Dropbox and Box.
