Millennium Ecosystem Assessment: Many of 2 billion dryland dwellers at risk as land degrades

...e downstream flooding, impairment of global carbon sequestration capacity, and regional and global climate change. "Given the size of population in drylands, the number of people affected by desertification is likely larger than any other contemporary environmental problem," says the report. Occupying more than ...

Measuring hidden parasites in falciparum malaria

...died. This finding fits with current thinking that sequestration of red cells containing the mature forms of the parasite is the most important pathological process in falciparum malaria. Approximately 40% of the world's population, mostly living in the world's poorest countries, is at risk of malaria. In the tr...

Amazon rainforest greens up in the dry season

...the global carbon cycle, which affects the natural sequestration and release of carbon dioxide, a major greenhouse gas. The finding that converted forests grow differently from undisturbed forests has implications for understanding fire regimes in the tropics, including the fires that sometimes rage in tropical a...

Parkinson's disease mechanism discovered

...ts toxicity is normally prevented in the neuron by sequestration within vesicles for transport from the ER. But a defect in ER trafficking caused by alpha-synuclein accumulation could cause the toxic buildup of dopamine to occur in these neurons." Lindquist and her colleagues believe their findings will guide the...

Nonvenomous Asian snakes 'borrow' defensive poison from toxic toads

...he PNAS paper, she and co-authors describe dietary sequestration of toxins by the snakes. The process allows the snakes to store toxins from the toads in their neck glands. When under attack, the snakes re-release the poisons from these neck glands. Many invertebrates sequester dietary toxins for use in defense...
