Chronic risks from single-use plastic water bottles are dangerously understudied, says study

The sun-drenched paradise of Thailand's Phi Phi islands isn't the usual starting point for a Ph.D. But for Sarah Sajedi, those soft, sandy beaches—or rather, what she found under them—inspired her pivot from a business ...

Newly discovered cell machinery breaks down protein aggregates into smaller pieces before 'taking it to the trash'

A new study from Aarhus University shows that our cells' ability to clean out old protein clumps, known as aggregates, also includes a—up till now unknown—partnership with an engine that breaks down bigger pieces into ...

System guides light through a tiny crystal, undeterred by bumps, bends and back-reflections

Relaying a message from point A to B can be as simple as flashing a thumbs-up at a stranger in an intersection, signaling them to proceed—nonverbal, clear, and universally understood. But light-based communication is rarely ...
