WCS says avian flu prevention should focus on farms, markets

...ct." According to WCS, avian influenza prevention activities should include better management practices in farms, especially small open-air farms where domestic poultry and waterfowl are allowed to intermingle with wild birds. Wildlife markets--where wild and domesticated species are kept in close proximity--a...

High carbon dioxide levels spur Southern pines to grow more needles

...higher levels of CO2 expected by 2050 due to human activities such as fossil fuel burning. Other stands are left as untreated controls for comparison. The elevated carbon dioxide is delivered from rings of towers in the open air setting of a Southern forest ecosystem. McCarthy found that, over the most recent ...

Oceans turning to acid from rise in CO2

...alarm about the world's oceans. "If CO2 from human activities continues to rise, the oceans will become so acidic by 2100 it could threaten marine life in ways we can't anticipate," commented Dr. Ken Caldeira, co-author of the report and a newly appointed staff scientist at the Carnegie Institution's Department...

What Makes The Brain Tick, Tick, Tick: Researchers Gaining New Insights Into Brain's Internal Clock

...brain's internal clocks coordinate a vast array of activities from communicating, to orchestrating movement, to getting food, they said. In a review article in the October 2005 Nature Reviews Neuroscience, Buhusi and Meck discuss the current state of understanding of one of the brain's most important, and myst...

Protein behind autumn color splendor identified

...lorophyll-binding proteins are the only ones whose activities can be observed from space. Working with the model plant mouse-ear cress (Arabidopsis thaliana), a research team at Umea Plant Science Center (UPSC), in association with a Polish scientist, has identified a protease that degrades LHCII. The resear...

Chernobyl: The true scale of the accident

Regenerating worms help elucidate stem cell biology

...ue lost to injury or shed during the body's normal activities is essential for the survival of most organisms. The new study, published in the November 25, 2005, issue of the journal Science, helps scientists understand how stem cells make this process possible.
