Scientists home in on alternatives to ‘forever chemicals’
Bulky molecules mimic some properties of PFAS without their long-lasting chemical bonds and could replace PFAS in some water-repelling applications.

Hundreds of millions of years before oxygen surged in the atmosphere 2.4 billion years ago, swaths of oxygen winked in and out of existence in the ocean.
News of NIH funding cuts have trickled out in recent months. A new study tallies what’s been terminated.
Some stinky plants independently evolved an enzyme to take the same molecule behind our bad breath and turn it into the smell of rotting flesh.
Chemists identify a single molecule that naturally tiles in nonrepeating patterns, which could help build materials with novel electronic properties.
Implanted tubes that transport bodily fluids can get gross. A lab prototype suggests a new vibration-based way to keep them clean and prevent infection.
