A new experiment confirms the existence of “superionic ice,” a bizarre form of water that might comprise the bulk of giant icy planets throughout the universe.

With proteins that reversibly self-assemble into droplets, cells may control their metabolism — and harden themselves against harsh conditions.

The astrochemist and winner of the 2018 Kavli Prize in Astrophysics has wondered about the cosmic origin of water while enjoying Noordwijk beach near her hometown of Leiden.

As chemists tie the most complicated molecular knot yet, biophysicists create a “periodic table” that describes what kinds of knots are possible.

By using the power of evolution to solve practical problems, three researchers opened new avenues to chemical discovery.

If and when physicists are able to pin down the metal content of the sun, that number could upend much of what we thought we knew about the evolution and life span of stars.

This year’s Nobel Prize in Chemistry goes to researchers who made it possible to see proteins and other biomolecules at an atomic level of detail.

Textbooks say that the moon was formed after a Mars-size mass smashed the young Earth. But new evidence has cast doubt on that story, leaving researchers to dream up new ways to get a giant rock into orbit.

The subtle mechanics of densely packed cells may help explain why some cancerous tumors stay put while others break off and spread through the body.
