Medicines and other small molecules may play a role in fixing rhythms gone awry
COMIC: The reef-builders face larger threats, scientists say. Chief among these is warming seas.
Fishery practices that go for the big ones may be counterproductive when mostly the small survive
Researchers dig out the elusive cats’ genetic material where they can, to guide efforts at conservation and diversity

The scientific literature is riddled with bad charts and graphs, leading to misunderstanding and worse. Avoiding design missteps can improve understanding of research.
A trio of researchers has mapped the living things that make the tongue, gums and palate home
The ancient pathogens in old graves are as dead as the people they once infected. Still, they tell a vivid tale.
How limestone-covered algae sway global climate — and how their fate may shift as the oceans acidify

On the edge of extinction, rare frogs and toads need more than a little love to reproduce. High-tech help, from IVF to hormone therapy, may save them.
By engineering mutations into fruit flies, scientists reconstructed how the butterflies may have evolved resistance to the toxins found in milkweed, allowing their caterpillars to feast on the plant
VIDEO: The humble bivalves can clean polluted water and bump up diversity — but there's plenty more to learn about the odd group of mollusks that make their homes in our streams and rivers
Researchers are developing microbe-propelled tiny bots to deliver drugs, target cancer or do other work in the body
In winter, the birds must remember where they’ve hidden tens of thousands of seeds. Biologist Vladimir Pravosudov explains what this can teach us about how the brain evolves.
Stegosaur expert Susie Maidment is laying crucial groundwork for assigning ages to fossils from North America’s most dinosaur-rich rocks. More precise timings promise to reveal plenty about how the beasts lived and evolved through time.
Complex mathematical tools are aiding the battle to identify invasive species before they get a foothold in the environment. But bureaucracy can blunt the techniques.
Revolutionary techniques using traces of environmental DNA are analyzing entire ecosystems “from microbes to whales”
The slimy stuff has a surprisingly wide array of beneficial biological functions
The humble bivalves can clean polluted water and bump up diversity — but in dammed rivers and fouled watersheds, many species face extinction. With help, maybe they can save themselves.
Our brains manage to construct stable images even as our eyes keep darting around. Here’s what we know about how that happens.
People have been using metals to manipulate light for centuries. Now researchers are using it to create powerful biosensors.
