Researchers at Princeton Engineering have found a way to turn your breakfast food into a new material that can cheaply remove salt and microplastics from seawater.

The researchers used egg whites to create an aerogel, a lightweight and porous material that can be used in many types of applications, including water filtration, energy…

NASA’s James Webb Space Telescope (JWST) has captured definitive evidence of carbon dioxide in the atmosphere of WASP-39b, a gas giant planet orbiting a sun-like star 700 light-years away.

“This discovery heralds the dawn of a new era in exoplanet research,” said Tansu Daylan, a Princeton astrophysicist who is one of the co-authors of…

Combining artificial intelligence and quantum mechanics, researchers at Princeton have simulated what happens at the molecular level when water freezes. The result is the most complete yet simulation of the first steps in ice “nucleation,” a process important for climate and weather modeling.

A new survey of the night sky has observed dark matter — the mysterious substance that makes up more than a quarter of the universe but emits no light of its own — as it existed 12 billion years ago, not long after the universe began. This oldest-ever snapshot of dark matter in the universe offers the tantalizing possibility that the…

New Princeton research shows that prehistoric megatooth sharks, the biggest sharks that ever lived, were apex predators at the highest level ever measured.

Megatooth sharks get their name from their massive teeth, which can each be bigger than a human hand. The group includes Megalodon, the largest shark that ever lived, as well as…
