In the early 20th century, orchardists in the Yakima Valley and other parts of the state were dealing with a menace. Apple orchards were plagued by codling moths, and for nearly a half century, fruit ...

The findings “show how a gatekeeper [protein] keeps arsenate out [of bacteria], so levels don’t accumulate and the bacteria don’t have to worry about toxic effects,” said Ronald Viola, a chemist at ...

With a detailed structure, researchers have discovered that a distorted hydrogen bond shapes how a bacterial protein distinguishes essential phosphate from toxic arsenate (Nature, DOI: ...

Arsenate esters are not sufficiently stable in water for the phosphorus-to-arsenic substitution implied in Felisa Wolfe-Simon’s paper to be functional, nor do the experiments reported in the paper ...

COMMERCIAL application of lead arsenate to citrus foliage has long been used to accelerate reduction of acidity in grapefruit. The effective moiety has been found to be arsenate. Control of citric ...

Prop counters, which are used gas-filled proportional counter detectors, were used by past generations of analyzers. The prop counter detection system provides broad peaks, thus zinc and copper were ...

Scientists reveal how bacteria living in arsenic-rich environments identify and expel the poison. Not long ago, some unassuming bacteria found themselves at the center of a scientific controversy: A ...
