To understand what might be lost, ecologist Janet K. Jansson taps molecular methods to explore Earth’s underground microbes, from the permafrost to the grasslands

Researchers dig out the elusive cats’ genetic material where they can, to guide efforts at conservation and diversity
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.
Only recently have scientists directly witnessed this most pivotal of events in biology, thanks to new technology that allows them to observe the process in living cells. It’s teaching them a lot.

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”
Scientists are finding that microscopic membranous bubbles called extracellular vesicles transmit messages from cells and do big jobs in many areas of biology — plus they might be useful for therapies.

The slimy stuff has a surprisingly wide array of beneficial biological functions
How limestone-covered algae sway global climate — and how their fate may shift as the oceans acidify
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.
For women, a short-term fling may involve a quest for good genes or just a good time. It’s a puzzle for the researchers looking at how people choose mates.
Agricultural economists are homing in on hybrid, low-input methods that will both safeguard the environment and feed the future billions
Feeding the planet — now and tomorrow — is no small task. Plant biologist Pamela Ronald says sustainability means using every tool in the toolbox.
A look inside the brains of engineered mice suggests therapies might need to target two key proteins — tau and amyloid-beta — at the same time
Ancient rocks suggest that ice entirely covered our planet on at least two occasions. This theory may help explain the rise of complex life that followed.
Many animals have the equipment for spoken language, but only people have all the right neural connections
Many types of marine plankton are either animal-like or plant-like. But a huge number are both, and they are upending ideas about ocean ecology.
