How bacteria adhere to fiber in the gut

Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the body. Scientists of the ...

How molecular clocks are refining human evolution's timeline

DNA holds the story of our ancestry – how we're related to the familiar faces at family reunions as well as more ancient affairs: how we're related to our closest nonhuman relatives, chimpanzees; how Homo sapiens mated ...

Israeli scientists say they can block melanoma spread

New map uncovers the traffic of life in a cell

Toronto scientists have recorded, in unprecedented detail, the locations of all proteins in a cell. This new protein map allows scientists to look much more closely into what happens in a cell when disease strikes, and will ...
