They call it stupid hot for a reason: Heat muddles animal brains

As temperatures rise, some creatures pick fights while others struggle to learn. The consequences of these behavioral changes may ripple through ecosystems.

Why we crave ‘comfort food’

Nostalgia plays a big role in the meals that bring us solace — which mean we might be able to recondition ourselves toward healthier foods that still soothe

The world has veered way off-target of its climate goals. Can we rebound?

Once global warming peaks, it could take centuries to cool things back down. But we can bend the curve by cutting fossil fuel emissions now.

The crazy nests built by leaf-cutter ants

Turrets and tunnels and carbon dioxide — oh my! These ants farm, but they are also master builders.

What’s the secret to a great cup of tea?

From where the Camellia sinensis bush is grown to whether the leaves are withered or fermented, much can influence the popular drink’s molecular and flavor profile

Stashing CO₂ in the sea

Keeping global warming to manageable levels will require removing carbon dioxide from the atmosphere and storing it somewhere else. The world’s oceans may be a promising option.

How new fishing tech can reduce bycatch of turtles and other creatures

Nets equipped with water bottles and other tricks can help save some species, while allowing fisherman to still catch others

Mining the deep ocean

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

The strange animals that control their body heat

Some creatures can dramatically alter their internal temperature — a strategy called heterothermy — and outlast storms, floods and predators

The curious case of low-protein diets

In the lab, animals live longer on less of the stuff. How could this be, and what does it mean for human aging?

The cataclysmic flood that wasn’t

Researchers have long believed that a sudden, massive deluge filled a dry, salt-filled Mediterranean some 5 million years ago. Turns out that probably didn't happen, but there was still drama aplenty.

Why disease outbreaks on Chinese fur farms are a serious risk to public health

Farming animals for fur is not only cruel but also provides an ideal environment for viruses to mix and cross over into humans

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

Beating back the Aedes aegypti mosquito

Scientists are taking a multipronged approach to tackle this dangerous carrier of dengue, yellow fever and other noxious viruses

Top science stories of 2025

In a year of funding chaos, ongoing climate change and pollution perils, we also saw the most powerful telescope yet, personalized gene therapy, and the next-best-thing to an HIV vaccine — not to mention a brand-new color

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
