Your DNA is flame_retardent


Italian researchers have found a new use for DNA: as a flame retardant. Coating cotton cloth with extracted DNA, the scientists found that the genetic material reduced the fabric’s flammability.

When heated, DNA’s phosphate-rich backbone produces phosphoric acid, which helps replace water in cotton fibers with a flame-retarding residue. At the same time, the bases, which contain nitrogen, produce ammonia, which inhibits combustion and interacts with the residue to form a protective shield over the cloth.

A treatment for prostate cancer


microRNA

A type of microRNA has been discovered that slows down the growth of prostate cancer cells, and could be used to improve treatments against the disease. Scientists noticed that many prostate cancer cells contained less of the microRNA molecule, and went on to reveal its absence allowed them to grow rapidly.

Parkinson disease protein spreads between neuron


The insidious spread of an abnormal protein may be behind Parkinson’s disease, a study in mice suggests. A harmful version of the protein crawls through the brains of healthy mice, killing brain cells and damaging the animals’ balance and coordination.
