Tropical insects 'go the distance' to inform rainforest conservation
... that we understand how these forests generate and sustain their diversity and what we can do to help conserve them.

... move to other places and find rich enough soil to sustain them. But with the world population now exceeding 6.6 billion people, Montgomery argues that there are few, if any, places left where the soil can feed a large population for very long. "We are skinning our agricultural fields," Montgomery said. "...Why nectar-feeding bats need a 'power drink' to fly
...en this phenomenal rate was still barely enough to sustain their metabolism when nectar was absent. This underlines how accurately these bats must balance their energy requirements every day and how vulnerable they are to ecological perturbations that might interrupt their fuel supply for even a short period...Accident-prone?

...also provided baseline data for athletes who might sustain a concussion after the season started, Swanik said. Visual memory, verbal memory, processing speed, and reaction time all were assessed. For example, a color-matching test was used to measure reaction time and processing speed. Each athlete was a...Researchers witness natural selection at work in dramatic comeback of male butterflies

Researchers are interested in the relationship between stem cells and their niche, because the niche represents a route for modifying stem cell behaviour if human ES cells can be reliably guided down a particular pathway, then they can be...Gene variations directly link inflammation to an increased risk for lung cancer

Over time, the constant damage of inflammation could lead to genetic damage and cancer, Engels said.

...rs were unable to make blood vessels and could not sustain their own growth, said Vivek Mittal, CSHL Assistant Professor. The findings open an entirely new field of research on how vascular progenitor cells control tumor growth and underscore their potential for cancer therapeutics.

Drugs able to target the oncogene and shut it down could offer an effective therapy for women whose tumor cells harbor the mutation. Th...New collaborative research reveals chimpanzees can sustain multiple-tradition cultures
