Traits from RNA molecules passed between multiple generations of worms can work with genetic changes to influence future evolution.

Studies that map the adaptive value of viral mutations hint at how the COVID-19 pandemic might progress next.

The spate of furious wildfires around the world during the past decade has revealed to ecologists how much biodiversity and “pyrodiversity” go hand in hand.

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.
