Chemistry

Sweet! The cell’s sugary coating comes into view

Built from thickets of glucose, galactose, mannose and more, the glycome plays key roles in cell communication, immunity and the blood-brain barrier

Recreating the smells of history

Using chemistry, archival records and AI, scientists are reviving the aromas of old libraries, mummies and battlefields

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

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

Postpartum depression: Better remedies, and now a predictive blood test

Scientists are learning more about this leading complication of childbirth. Treatments are improving and doctors can test for biological markers that flag heightened risk.

Tracking down the hidden pollutants that make wildlife sick

A new technique for detecting unknown and unlooked-for chemicals is revealing dozens of contaminants in alligators, sea lions and condors

Using pollen to make paper, sponges and more

Reengineered, the powdery stuff could become a range of eco-friendly objects

Watching the world, one quintillionth of a second at a time

An attosecond is no time at all for a person. Not so for electrons, atoms and molecules. Laser-wielding scientists are revealing the action.

At the dawn of life, did metabolism come first?

Some scientists propose that in the beginning, geochemistry gave way to biochemistry — with no genetic material necessary. Only later did RNA and DNA appear.

The caterpillars that can kill you

Some species make venoms that are deadly. With more research, those toxic compounds could yield useful medicines.

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.

These proteins have been secretly managing your cells

Scientists have long known that histones spool DNA and help regulate genes. They may be doing a lot more.

Radioactive drugs strike cancer with precision

The tumor-seeking radiopharmaceuticals are charting a new course in oncology, with promise for targeted treatments with fewer side effects

Cleaning up cow burps to combat global warming

New tools for lowering methane emissions from livestock are on their way

Toward truly compostable plastic

Materials scientists are cooking up environmentally friendly polymers from natural sources like silk, plant fibers and whole algae. Economics and acceptance remain hurdles.

Central American volcanoes offer clues to Earth’s geological evolution

Along 1,100 kilometers, from Mexico to Costa Rica, lies the Central American volcanic arc, where the variety of magma types make for a geological paradise

Why scientists are making transparent wood

Stronger than plastic and tougher than glass, the resin-filled material is being exploited for smartphone screens, insulated windows and more

Saliva: The next frontier in cancer detection

Scientists are finding tumor signals in spit that could be key to developing diagnostic tests for various types of cancer

Scientific highs and lows of cannabinoids

Hundreds of these cannabis-related chemicals now exist, both natural and synthetic, inspiring researchers in search of medical breakthroughs — and fueling a dangerous trend in recreational use
