Copper chelation is a promising new therapy for clogged arteries
...ies following balloon angioplasty can be halted by copper chelation therapy. Preventing the function of copper in the body stops arteries from reclogging following the mechanical stress of removing arterial obst...Scientists find evidence for crucial root in the history of plant evolution
... This involved mounting the fossil impression on a copper grid and bombarding it with a brilliant focused beam of X-rays in the "soft" range between 200-900 electron volts. Biological elements, such as carbon, nitrogen and oxygen, exhibit characteristic absorption in this unusual energy range, Cody says. ...Metal ions may play big role in how we sense smells
