Researchers use brain scans to predict behavior

... punishments," d'Avossa says. "It also may help us build up predictions of what the world should be like and how certain events go together. When it works well, the world makes sense to you." Sapir noted that the reward systems' predictive abilities may be damaged or missing in some patients with mental ...

Anthrax stops body from fighting back, study shows

...t defense against infection, by impairing how they build tiny filaments that allow them to crawl throughout the body and eat invading bacteria. Just two hours of exposure to the lethal toxin blocks the neutrophils' ability to produce these filaments by nearly 60 percent, paralyzing themand allowing the a...

Wolves' top-down effect

...ould no longer find sufficient trees with which to build their dams," says Hebblewhite. In addition, songbirds, such as the American Redstart, which is strongly dependent on willow, also vanished from the wolf-excluded area. Although the presence of people in the Bow Valley area also kept away other larg...

Max Planck researchers make a breakthrough in plant stem cell research

Totipotent stem cells allow plants to build new organs throughout their whole life. But it has been unclear how hormones and genetic factors work together to prevent plants from having growth that is either stunted, or uncontrolled and tumor-like. Scientists from the Max Planck Institute for D...

Scientists pinpoint inflammation gene

... that helps clear cells of misfolded proteins that build up when cells are placed under stress, Blangero said. Inflammation develops when those faulty proteins accumulate in a cell. People with a genetic variation that impairs SEPS1' ability to purify the cells by clearing out the bad proteins tend to su...

New brain scan technology could save babies' lives

...eloped with EPSRC funding uses this information to build up a 3D image. This can show which parts of the brain are receiving oxygen, where blood is situated, evidence of brain damage etc. MONSTIR is the size of a fridge-freezer and takes around 8 minutes to generate an image. The aim is to produce a vers...

Scientist uses form to explain function of key building blocks of life

...nges in protein function. "In science, you try to build theories that will explain the properties of the systems you are looking at," explains Markley. "Proteins are the basic building blocks of life, and are coded for by the genes in DNA. We'd like to be able to start with a gene sequence and predict th...

Researchers make long DNA 'wires' for future medical and electronic devices

...rs," Lee said. "And in our case, we want to try to build tools for gene delivery, DNA recombination, and maybe even gene repair, down the road." The longest strands are one millimeter (thousandths of a meter) long, and only one nanometer (billionths of a meter) thick. On a larger scale, positioning such a...

Seal rookeries could provide a reliable food source for endangered California condors, study finds

...the condors." He says that plans are under way to build a new holding pen along the coast south of Big Sur where seals frequently haul out. "Free-flying condors are just not finding these areas yet so we need to encourage them to do so," he adds. Other major haul-outs can be found from Baja California to ...
