Mechanical tension between tethered cells cues developing tissues to fold. Researchers can now program synthetic tissue to make coils, cubes and rippling plates.

Near an Australian desert mining camp, wild dingoes are losing their fear of humans. Their genetic and behavioral changes may echo those from the domestication of dogs.

The dizzying network of interactions within microbe communities can defy analysis. But a new approach simplifies the math and makes progress possible.

By developing new tools for visualizing subcellular structure and activity in molecular detail, Ed Boyden advances on his goal of understanding how the brain works.

Compact genomes and tiny cells gave flowering plants an edge over competing flora. This discovery hints at a broader evolutionary principle.

Evolution settled on a genetic code that uses four letters to name 20 amino acids. Synthetic biologists adding new bases to DNA will be free to improve on nature — if they can.

This holiday season, catch up on science and math news while solving our year-end crossword.

Corina Tarnita deciphers bizarre patterns in the soil created by competing life-forms.

For decades, an origin-of-life story starring RNA has prevailed. New research may be shaking that theory’s hold on our understanding of life’s beginnings.
