Flying with whales: Drones are remaking marine mammal research

From collecting whale snot to capturing surprising behaviors, aerial drones are giving scientists a new view of life at sea

Alternative proteins that replace meat in our diets may take many forms in the future. A collage shows chickpeas, seaweed, tofu, kidney beans, a package of Impossible soy-based
Food & Environment

What is the protein of the future?

OPINION: It’s sustainable, nutritious and delicious. Scientists need to ramp up efforts to meet this urgent need.

A scanning electron micrograph that is colored green shows stomata, with the look of small donuts, surrounded by other more irregularly shaped plant cells.

Can tinkering with plant pores protect crops against drought?

It’s not an open-and-shut case. But researchers are finding out plenty by genetically altering the numbers of these openings, as well as simulating future atmospheres, and more.

The science of green hair care

A push to move away from petroleum products — plus the perception that natural is gentler — has scientists lathering up new ingredients, from wood and fungus extracts to engineered proteins

Meet the mysterious electrides

These chemical oddities may explain why Earth seems to be deficient in certain elements — and could prove useful in catalysts and more

Cracking the recipe for perfect plant-based eggs

Hint: It involves finding just the right proteins. With new ingredients and processes, the next generation of substitutes will be not just more egg-like, but potentially more nutritious.

Mining the deep ocean

Renewable technologies need a multitude of critical minerals. The seabed could supply these riches. But at what cost?

A scientific mission to save the sharks

Despite increasing protection measures, these fish are among the world’s most endangered animals. New tests to detect species being traded, as well as population studies, aim to help save them.

Not enough fish in the sea

The scientist who found a way to tally up global catches is an ocean advocate and a vocal critic of industrial fisheries. Now we have a treaty for the high seas — but does it go far enough?

The history of the ocean, as told by tiny beautiful fossils

Bountiful remains of foraminifera reveal how organisms responded to climate disturbances of the past. They can help predict the future, too.
