Nymphaea lotus.
Approximately 120-130 million years ago, one of the most significant events in the history of the Earth occurred: the first flowering plants, or angiosperms, arose. In the late 1800s, Darwin referred to their development as an “abominable mystery.” To this day, scientists are still challenged by this “mystery” of how angiosperms originated, rapidly diversified, [...]

Researchers have identified a cellular pathway that may explain the link between alcohol consumption and cancer.

Alcohol consumption has long been linked to cancer and its spread, but the underlying mechanism has never been clear. Now, researchers at Rush University Medical Center have identified a cellular pathway that may explain the link.

When two populations of a species become geographically isolated from each other, their genes diverge from one another over time.
Cornell researchers have discovered a genetic mechanism in fruit flies that prevents two closely related species from reproducing, a finding that offers clues to how species evolve.
