New Investigation Cuts Through the Haze Surrounding &#8216;Smoke-Free&#8217; Tobacco Products

Marketed as a healthier alternative to cigarettes, a new class of tobacco products called heat-not-burn devices is quickly gaining in popularity across the globe. A study by Berkeley Lab’s Indoor Environment Group shows that, although the chemical emissions from these devices are lower than those produced by conventional cigarettes, they are still high enough to raise concern.

Tiny Toxins: How Algal Blooms Affect Coastal Systems Through a Complex Web of Interactions

A Q&A with scientist Michelle Newcomer on looking for unexpected causes of harmful algal blooms. Harmful and nuisance algal blooms are thought to have a number of contributing causal factors, including a build-up of nutrients, unusually high water temperatures, and extreme weather events such as floods and drought. But an understanding of the connectivity between these triggers is missing, as is an ability to predict the onset of the blooms.
