Choosing your neighbors: Scientists see how microbes relate in space
Like people in cities, microbes often live in complex communities that contain many different microbial types. Also like us, microbes tend to gravitate to and "hang out" with certain other types in their community, ...

Evolution led to genetic variation that may affect diabetes, scientist says
The root causes of complex diseases such as type-2 diabetes and obesity have been difficult to identify because the diseases are, well, complex. They occur at the dicey biological intersection of genes and environment, and, ...

Cancer in a single catastrophe
Most of the time cancer seems to creep up gradually over time; cells become premalignant, then increasingly abnormal before they become cancerous. But sometimes cancers seem to pop up as if out of nowhere. Now, researchers ...

Punctuated evolution in cancer genomes
Remarkable new research overthrows the conventional view that cancer always develops in a steady, stepwise progression. It shows that in some cancers, the genome can be shattered into hundreds of fragments in a single cellular ...
