Phys.org / Traditional plastic forks shed harmful microplastics. Plastic created from sugar is an alternative

At a Massachusetts lab, pebble-sized pellets are transformed into forks and films that won't leave persistent microplastics in the environment.

Dialog / Quantum heat circuits learn electronics' oldest trick: Sharing a power supply

Every electronic and optoelectronic device generates heat, and today that heat is managed almost entirely from the outside. Heatsinks, fans, cold plates and refrigerators are bulky exterior measures bolted onto a chip or ...

Phys.org / DNA repair enzymes favor specific sequences, shaping mutation patterns in the human genome

When a wound does not heal properly, it leaves a scar. Similarly, mutations—which are permanent changes to genetic code—are often the result of damaged DNA that has not been properly repaired. Mutations can impede the function ...

Phys.org / Uncovering how Cryptococcus shifts from silent infection to killer fungus

For most healthy people, Cryptococcus is an unnoticed infection. The immune system walls it off in the lungs and keeps it dormant for life. But in patients undergoing cancer chemotherapy, recovering from an organ transplant, ...

Phys.org / Climate change could mean four extra hours of extreme heat on hot days

Hot days could gain more than four additional hours of extreme heat by the end of the 21st century under a high-emissions scenario, according to a modeling study published in Nature Climate Change. The findings show that ...
