For almost 50 years, astronomers have puzzled over the youthful appearance of stars known as blue stragglers.

Scientists have discovered two genes that, when simultaneously activated, are responsible for the most aggressive forms of brain cancer. This finding was made possible by the assembly of the first comprehensive network of molecular interactions that determine the behavior of these cancer cells, a map so complex and elusive that, until now, it could not [...]

Much like a tightly wound drum, red blood cells are in perpetual vibration. Those vibrations help the cells maintain their characteristic flattened oval or disc shape, which is critical to their ability to deform as they traverse blood vessels in the body to deliver oxygen to tissues.

Type 2 diabetes is a major global health problem. Although the underlying mechanism of the pathogenesis is not clear, generally it is accepted that type 2 diabetes is a result of gene-environment interactions. A research group from China investigated the relationship between the metabolism of nicotinamide and diabetes and found that nicotinamide overload may be [...]

Conservationists have long known that lines on a map are not sufficient to protect nature because what happens outside those boundaries can affect what happens within. Now, scientists have measured the threat of housing development around protected areas in the United States.

From beetles to barnacles, pikas to pine warblers, many species are already on the move in response to shifting climate regimes. But how fast will they — and their habitats — have to move to keep pace with global climate change over the next century? Scientists have calculated that on average, ecosystems will need to [...]
