Large blocks of genes conserved through hundreds of millions of years of evolution hint at how the first animal chromosomes came to be.

The electrical chatter of our working memories reflects our uncertainty about their contents.

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

New studies reveal the ancient, shared genetic “grammar” underpinning the diverse evolution of fish fins and tetrapod limbs.

The detailed understanding of brains and multicellular bodies reached new heights this year, while the genomes of the COVID-19 virus and various organisms yielded more surprises.

When scientists discover genes linked to dangerous illnesses in their samples, how should they convey that news to the study participants? The geneticist Cristen Willer had to tackle that challenge.

Rapid advances in large-scale connectomics are beginning to spotlight the importance of individual variations in the neural circuitry. They also highlight the limitations of “wiring diagrams” alone.

No matter how much we’d like to eradicate SARS-CoV-2, it may be better to settle for other forms of control.

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.
