Poplar DNA code cracked -- a step in combating global warming?
... plants, and thus trees as well, are also found in human
and animal life. But this research can also lead to particular applications in fields such as ecology. A thorough genetic knowledge enables researchers to modify trees genetically for the benefit of humankind and the environment. The genome sequence...
Scientists find nanowires capable of detecting individual viruses

Study explores gene transfer to modify underlying course of Alzheimer's disease
.... The active part of the drug is the NGF gene, the human
DNA strand that codes for the NGF protein, a natural substance that exerts positive effects on brain cells. A key objective of the study is to deliver the CERE-110 directly to the part of the brain that is almost universally affected by Alzheimer's d...

Environmental decontamination, greenhouse gases, and the genome of a methane-loving bacterium
...els of atmospheric methane have been attributed to human
activity, mostly in the form of landfills, natural gas and oil processing (about 60%), domesticated livestock (cattle account for about 75% of livestock contributions), and rice fields (up to 29% of total emissions). Luckily, there are microbes, ...
Binocular rivalry: Fulfilling visual expectations
...ocessing, the experimenters used images of walking human
figures visible only via lights placed on their joints. This sparse visual stimulus has long been known to provide a compelling impression of a walking person. When a walking figure was presented to each of the two eyes, perception alternated between...
