Plastic is everywhere in our daily lives. And much of what we use, such as cutting boards, clothes and cleaning sponges, can expose us to tiny, micrometer-wide plastic particles called microplastics. Now, chewing gum could be added to the list. In a pilot study, researchers found that chewing gum can release hundreds to thousands of microplastics per piece into saliva and potentially be ingested. The researchers will present their results at ACS Spring 2025.
Deep below the Earth’s surface, rock and mineral formations lay hidden with a secret brilliance. Under a black light, the chemicals fossilized within shine in brilliant hues of pink, blue and green. Scientists are using these fluorescent features to understand how the caves formed and the conditions for supporting life in extreme, and even extraterrestrial, environments. The researchers will present their results at ACS Spring 2025.
The condition of the grass on a golf course can drastically skew the chances of a winning putt regardless of a player’s skill. Now, a coating that soaks up water molecules could slow the roll of a golf ball on a lightning-fast, dry course and speed it up on a sluggish, wet course without interfering with the ball when it’s airborne. The researcher will present his results at ACS Spring 2025.
When wildfires threaten communities, human health can be impacted as smoke distributes on the breeze, infiltrating various structures. To help people protect themselves and their families, researchers have developed a low-cost, durable, do-it-yourself air filtration system that works as well as more expensive HEPA filters to clear indoor air pollutants such as smoke — or possibly limit the impact of airborne disease spread. They will present their results at the ACS Spring 2025 Digital Meeting.
Dogs have many jobs but one you may not expect is identifying grapevines with a destructive and highly contagious fungus called powdery mildew. Researchers are analyzing volatile chemicals emanating from grape leaves infected by powdery mildew, with the goal of improving training for vineyard canines. The researchers will present their results at ACS Spring 2025.
