Powerful New Paint May Kill Super-Bugs

Researchers in South Dakota have developed a broad-spectrum, anti-microbial paint that will not only kill disease-causing bacteria, but also mold, fungi, and viruses. The paint is designed to decorate and disinfect homes, businesses, and health-care settings. The scientists said that the paint holds special promise of effectiveness in killing so-called "super-bugs," antibiotic-resistant microbes that cause an estimated 88,000 deaths annually in the United States. The new paint contains a new anti-microbial polymer that includes a type of N-halamine. The researchers note that anti-microbial paints already on store shelves are only effective against a narrow range of disease-causing organisms, limiting their effectivenss. The work is described in the journal Applied Materials & Interfaces, published by the American Chemical Society. [ACS press release] [Journal abstract]

Miolecular Secret of Turmeric Spice Finally Revealed

Scientists believe they have discovered the mechanism by which turmeric, a spice revered in India as "holy powder," exerts its fabled healing powers. Turmeric has been used for centuries in folk medicine to treat wounds, infections, and other health problems. Using solid-state NMR spectroscopy, the scientists discovered that molecules of curcumin, the key ingredient in turmeric, insert themselves into cell membranes and make the membranes more stable and orderly in a way that increases cells' resistance to infection by disease-causing microbes. The results were published in the Journal of the American Chemical Society. [JACS article]
