A mathematical model shows how a thermodynamic mechanism could have made protocells split in two.

Driven by her fascination with highly repetitive, hard-to-read parts of our DNA, Karen Miga led a coalition of researchers to finish sequencing the human genome after almost two decades.

Recent findings add weight to the evidence that the intransitive competitions between species enrich the diversity of nature.

Taste and smell receptors in unexpected organs monitor the state of the body’s natural microbial health and raise an alarm over invading parasites.

Genetically identical bacteria should all be the same, but in fact, the cells are stubbornly varied individuals.

In harsh ecosystems around the world, microbiologists are finding evidence that “microbial seed banks” protect biodiversity from changing conditions.

Disease-causing viruses and message-carrying vesicles sit at the ends of a spectrum of membranous particles that cells release.

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