Molecular 'Claws' Trap Arsenic Atoms: Discovery Could Eventually Lead To Improved Treatments For Arsenic Poisoning Date: November 17, 2004 Source: ...

Arsenic, a chemical element, is prevalent in the Earth’s crust, though its levels can vary depending on the region and the medium such as air, water, or soil. Get to know some of the most common ...

Arsenic atoms cannot resist a new molecule that traps and sequesters them. The discovery by chemists at the University of Oregon is a promising first step toward eventual development of ...

To confirm that this arsenic was being incorporated into DNA, she used a well-accepted molecular biology technique known as gel purified DNA extraction to isolate and concentrate DNA from GFAJ-1 ...

Arsenic is a chemical element that occurs naturally in the environment. In its organic form, with a carbon molecule attached, it is harmless. But it is highly toxic in its inorganic form, ...

Brown rice has long been seen as white rice's better, healthier brother—but new research raises a red flag over potential ...

"Arsenic is toxic mainly because its chemical behavior is so similar to that of phosphorus," said researcher Ariel Anbar, a biogeochemist and astrobiologist at Arizona State University.

Say it out loud: Arsenic. Even the name leaves a toxic taste on the tongue. And despite the chemical’s reputation as a way to, uh, “eliminate” one’s spouse (really—arsenic p… ...

Scientists fabricate sensitive nanostructured silver surfaces to detect arsenic, even at very low concentrations. The sensors make use of surface-enhanced Raman spectroscopy: As a molecule ...
