Fighting fire with fire: 'Vampire' bacteria has potential as living antibiotic

Posted: 31 Oct 2011 07:06 PM PDT

A vampire-like bacteria that leeches onto specific other bacteria -- including certain human pathogens -- has the potential to serve as a living antibiotic for a range of infectious diseases, a new study indicates.

Live longer with fewer calories? Key enzyme involved in aging process found

Posted: 31 Oct 2011 06:59 PM PDT

By consuming fewer calories, aging can be slowed down and the development of age-related diseases such as cancer and type 2 diabetes can be delayed. The earlier calorie intake is reduced, the greater the effect. Researchers have now identified one of the enzymes that hold the key to the aging process.

Researchers have shed light on the inner workings of the endocycle, a common cell cycle that fuels growth in plants, animals and some human tissues and is responsible for generating up to half of the Earth's biomass.

Bacteriophages mobilize the antibiotic resistance of bacteria in the environment

Posted: 28 Oct 2011 05:20 AM PDT

The role of bacteriophages -- viruses that infect bacteria -- could be crucial in the transfer of antibiotic resistance genes between bacteria, and this process could favor the emergence of resistant bacterial strains in the natural environment.
