With moderate heat, enzyme-laced films of the plastic disintegrated in standard compost or plain tap water within days to weeks, Ting Xu and her colleagues

“Biodegradability does not equal compostability,” says Xu, a polymer scientist at the University of California, Berkeley and Lawrence Berkeley National Laboratory. She often finds bits of biodegradable plastic in the compost she picks up for her parents’ garden. Most biodegradable plastics go to landfills, where the conditions aren’t right for them to break down, so they degrade no faster than normal plastics.

In 2014, two years after her Nobel Prize-winning invention of CRISPR-Cas9 genome editing, Jennifer Doudna thought the technology was mature enough to tackle a cure for a devastating hereditary...

Keeping enemies on the run is all part of the job for soldiers in the U.S. Army, yet troops stationed in the world’s hot spots frequently face another relentless foe: thirst. But scientists at GE Research and their partners at U.S. universities including ...

Visionary biochemist Jennifer Doudna shared the Nobel Prize last year for the gene-editing technology known as CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats), which has the potential to cure diseases caused by genetic mutations. Correspondent David Pogue talks with Doudna about the promises and perils of CRISPR; and with Walter Isaacson, author of the new book "The Code Breaker," about why the biotech revolution will dwarf the digital revolution in importance.
