Bacteria Successful In Cancer Treatment

Bacteria that thrive in oxygen starved environments have been used successfully to target cancer tumours, delivering gene therapy based anti-cancer treatments.

Humans have many more copies of this gene than any of their ape relatives, the study found, and they use the copies to flood their mouths with amylase, an enzyme that digests starch. The finding bolsters the idea...

Females Promiscuous For The Sake Of Their Grandchildren

Female animals that mate with multiple partners may be doing so to ensure the optimum health of their grandchildren, according to researchers. Despite mating being a risky business for females -- not least with the threat of injury, sexually transmitted diseases and vulnerability to predators - polyandry (females taking multiple mates) is widespread in the animal kingdom.
