Pillar-like molecules as biosensors for metabolites

Researchers report that a molecule known as pillar[6]arene can form a host-guest compound with a cancer-associated metabolite. The phenomenon can be used to efficiently detect the metabolite in crude biological samples, which is important for preventing and treating metabolic syndrome and associated pathologies.

Mediterranean diet may decrease risk of prostate cancer progression

In a study to examine a Mediterranean diet in relation to prostate cancer progression in men on active surveillance, researchers found that men with localized prostate cancer who reported a baseline dietary pattern that more closely follows the key principles of a Mediterranean-style diet fared better over the course of their disease.

Boosting vegetable oil production in plant leaves

A professor has found a way to boost the production of triacylglycerol — the main component of vegetable oil — in plant leaves, a technique that could allow producers to harvest oil from large, leafy plants that also have other uses. Sorghum, for example — a global source of grain prized for its drought-resistant qualities — could serve a dual role as a source of vegetable oil, creating a more efficient and valuable crop.

Several U.S. populations and regions exposed to high arsenic concentrations in drinking water

A national study of public water systems found that arsenic levels were not uniform across the U.S., even after implementation of the latest national regulatory standard. In the first study of differences in public drinking water arsenic exposures by geographic subgroups, researchers confirmed that community water systems reliant on groundwater, serving smaller populations located in the Southwest, and Hispanic communities were more likely to continue exceeding the national maximum containment level, raising environmental justice concerns.

Researchers develop plant nanobionic sensor to monitor arsenic levels in soil

Researchers have developed — for the first time — a novel type of plant nanobionic optical sensor that can, in real-time, detect and monitor arsenic levels in the belowground environment, with significant advantages over conventional methods used to measure arsenic in the environment. The new sensor will improve arsenic detection and will help safeguard food safety, and will be useful for agricultural research and environmental monitoring.
