Study of salts in water causing stir

New insight into science that seems, on its surface, exceedingly simple—what happens when you add salt to water—could ultimately lead to a better understanding of biochemical processes in cells and perhaps advance sources ...

Experts: Idaho hatchery built to save salmon is killing them

A relatively new $13.5 million hatchery intended to save Snake River sockeye salmon from extinction is instead killing thousands of fish before they ever get to the ocean, and fisheries biologists in Idaho think they know ...

A better way to wash pesticides off apples

Polishing an apple with your shirt might remove some dust and dirt, but getting rid of pesticide residues could take a little more work. Researchers now report in ACS' Journal of Agricultural and Food Chemistry, that washing ...

Brewing a great cup of coffee depends on chemistry and physics

Coffee is unique among artisanal beverages in that the brewer plays a significant role in its quality at the point of consumption. In contrast, drinkers buy draft beer and wine as finished products; their only consumer-controlled ...

New catalysts efficiently and rapidly remove BPA from water

Carnegie Mellon University chemist Terrence J. Collins has developed an approach that quickly and cheaply removes more than 99 percent of bisphenol A (BPA) from water. BPA, a ubiquitous and dangerous chemical used in the ...

Scientists tackle toxin particle capture

As lakes and waterways are threatened by end-of-summer blue-green algae that produce cyanotoxins – compounds with potent toxicity to humans and pets – a new Cornell study shows how water chemistry controls the way toxic ...
