Rather than focusing on scary symptoms, the We Campaign focuses on the cure for global warming — and motivates people to support sweeping change. Question is, will it be enough to effect any real change at all?

West Australian health experts are urging older people to get active after proving for the first time that just twenty minutes of activity each day can prevent memory deterioration. In a world-first, a team from the WA Centre for Health and Ageing (WACHA) based at the Western Australian Institute for Medical Research (WAIMR) has shown that regular physical activity can lead to a lasting improvement in memory function.
Woolly mammoths native to what's now the U.S., says study

Recent DNA tests of preserved DNA have allowed us to sort prehistoric mammoths into three groups: One subspecies lived in Eurasia, one in North America, and another ranged through both. For a long time, it was thought that mammoths originated in Eurasia because the fossils that have been found there are older. While this seems to be true, the studies also show that the subspecies that arose in North America crossed the Bering Strait and supplanted the other two a few hundred thousand years ago.

A study discovered that the fly anticipates the direction of a looming threat and makes split-second movements that better prepare it to take off in the opposite direction. The findings reveal a level of movement planning rarely seen in such a simple organism.
Republican presidential platform would ban all human embryonic research

The Republican presidential platform proposes banning all human embryo research throughout the United States. Although John McCain himself has voted to loosen federal restrictions on stem cell funding, the party that supports him appears to be taking a more conservative line.
But for the grammar enthusiasts among us, the change in the platform was effected with one word. They canged "and" to "or," so that they call for a ban on the "the creation of or experimentation on human embryos for research purposes
New mutant collection examines six thousand genes. Next big thing in drug discovery?
jerry submitted, created time 5 days 44 minutes (stke.sciencemag.org)
A major challenge in drug discovery is to identify the cellular targets responsible for the pharmacological activity of drug candidates. In the yeast Saccharomyces cerevisiae, a heterozygous diploid mutant collection of approximately six thousand strains, in each of which one copy of a single gene is deleted, is commercially available. With this collection, it is possible to evaluate the role of each gene product in the response of cells to a drug
Scientists develop new method to investigate origin of life
sea-maid submitted, created time 4 days 4 hours (esciencenews.com)
Scientists at Penn State have developed a new computational method that they say will help them to understand how life began on Earth. The team's method has the potential to trace the evolutionary histories of proteins all the way back to either cells or viruses, thus settling the debate once and for all over which of these life forms came first. "We have just begun to tap the potential power of this method," said Randen Patterson, a Penn State assistant professor of biology and one of the project's leaders
