Arsenic contamination of soils presents severe risks to human health and ecosystems, primarily due to the high toxicity and mobility of arsenite [As (III)]. While arsenate [As (V)] is less toxic ...

1. Norman Pace, University of Colorado: I don't have much to add to the buzz that's around. As-DNA [DNA with arsenic in its backbone] is unlikely because of the instability of the arsenate linkage as ...

Walmart recalled nearly 10,000 cases of apple juice sold in over 25 states across the U.S. due to concerns of high levels of inorganic arsenic, according to an Aug. 15 recall notice from the U.S ...

Cong Tu, Lena Q. Ma, Effects of arsenate and phosphate on their accumulation by an arsenic-hyperaccumulator Pteris vittata L., Plant and Soil, Vol. 249, No. 2 (February (II) 2003), pp. 373-382 ...

Phosphate is also vital for other molecules, such as proteins, and the scientists found arsenate in them as well. In other words–arsenic-based life. Or…maybe not.

“You can grow a bug in arsenic-rich media and you will see some arsenate,” says geobiologist Tanja Bosak of MIT. But that does not mean the arsenate is in the DNA, she says.

Salt’s team found that rice plants without working genes for enzymes called HAC1;1 and HAC1;2 couldn’t turn arsenate into arsenite. So more arsenate accumulated in the plants’ shoots.

Alert readers will remember the scuffle that broke out last summer December over the “arsenic-is-life” paper by Felisa Wolfe-Simon and colleagues that claimed to have found that a bacterium ...

Chromated Copper Arsenate is used to protect wood from dry rot, mold and termites. It's found in wood used for decks, picnic tables, playground equipment.
