Having more cells usually puts one at a higher risk for cancer - but not for the elephant. Despite packing 100 times as many cells as humans, this towering animal can keep cancer at bay thanks to extra copies of a tumor-fighting gene. Researchers found that Asian elephants harbor 30 to 40 copies of the gene that encodes the protein p53, one of the most important mechanisms for preventing cancer and maintaining cell division. If cells have DNA damage that could spawn tumors, p53 prevents them from dividing until they make repairs or spurs them to commit suicide. In contrast, humans sport only two copies of the gene for p53, and so does elephants’ closest living relative, the rock hyrax. The extra copies probably accumulated millions of yea ...

New research from the University of Chicago in the US shows that a class of bacteria known as Clostridia can block peanut allergies in mice, and suggests it could be used to treat similar conditions in humans.

Clostridia is one of the types of bacteria killed off by antibiotic use in early childhood, and this research supports the emerging theory that increased antibiotic use is one of the factors that has caused food allergies in kids to rise by 50% since 1997.
