The oldest law of genetics says that gametes combine randomly, but experiments hint that sometimes eggs select sperm actively for their genetic assets.

A number of high-energy anomalies raised hopes that astrophysicists had seen their first direct glimpses of dark matter. New studies suggest a different source may be responsible.

Bacterial biofilms and slime molds are more than crude patches of goo. Detailed time-lapse microscopy reveals how they sense and explore their surroundings, communicate with their neighbors and adaptively reshape themselves.

In applying game theory to biology and human behavior, have scientists focused too much on competition over cooperation?

Astronomers are mystified by a strange star explosion in a distant galaxy that might be a relic from an earlier cosmological era.

Elephants did not evolve to become huge animals until after they turned a bit of genetic junk into a unique defense against inevitable tumors.

The Zoomable Universe, a new book by the astrobiologist Caleb Scharf, the illustrator Ron Miller and 5W Infographics, tours the universe’s 62 orders of magnitude.

When equipped with hidden layers, deep neural networks can accomplish nonlinear feats that are difficult even with sophisticated mathematics.

Which mattered first at the dawn of life: proteins or nucleic acids? Proteins may have had the edge if a theorized process let them grow long enough to become self-replicating catalysts.
