How ‘Long COVID’ Keeps Us Sick
Other diseases with long-term symptoms can help us understand how COVID can affect us long after the virus itself is gone.
A Lack of COVID-19 Genomes Could Prolong the Pandemic
Genomic surveillance of the SARS-CoV-2 virus can help control the current pandemic and prevent future ones. But the process is marred by insufficient data and geographic inequities.
Secret Workings of Smell Receptors Revealed for First Time
Researchers have finally seen how some smell receptors bind to odor molecules. The work yields new insights into one of the most mysterious and versatile senses.
How Animals Color Themselves With Nanoscale Structures
Animals sculpt the optical properties of their tissues at the nanoscale to give themselves “structural colors.” New work is piecing together how they do it.
DNA Jumps Between Animal Species. No One Knows How Often.
The discovery of a gene shared by two unrelated species of fish is the latest evidence that horizontal gene transfers occur surprisingly often in vertebrates.
RNA Brakes May Stabilize a Cellular Symbiosis
In some symbiotic partnerships, an RNA-based mechanism may sabotage the growth of greedy hosts.
Radioactivity May Fuel Life Deep Underground and Inside Other Worlds
New work suggests that the radiolytic splitting of water supports giant subsurface ecosystems of life on Earth — and could do it elsewhere, too.
Sleep Evolved Before Brains. Hydras Are Living Proof.
Studies of sleep are usually neurological. But some of nature’s simplest animals suggest that sleep evolved for metabolic reasons, long before brains even existed.
Eve Marder on the Crucial Resilience of Neurons
Eve Marder’s research into the plasticity and resilience of nervous systems finds universal principles guiding life’s responses to stress.
