Scientists see 'sloshing' galaxy cluster

Posted: 30 Jan 2012 02:24 PM PST

Scientists have recently discovered that vast clouds of hot gas are "sloshing" in Abell 2052, a galaxy cluster located about 480 million light years from Earth.

Music training has biological impact on aging process

Posted: 30 Jan 2012 02:24 PM PST

Age-related delays in neural timing are not inevitable and can be avoided or offset with musical training, according to the first study to provide biological evidence that lifelong musical experience impacts the aging process. Measuring automatic brain responses of younger and older musicians and non-musicians to speech sounds, researchers found older musicians not only outperformed older non-musicians, they also encoded sound stimuli as quickly and accurately as younger non-musicians.

Mouse to elephant? Just wait 24 million generations

Posted: 30 Jan 2012 02:19 PM PST

Scientists have for the first time measured how fast large-scale evolution can occur in mammals, showing it takes 24 million generations for a mouse-sized animal to evolve to the size of an elephant.

Chimp 'X factor': Extensive adaptive evolution specifically targeting the X chromosome of chimpanzees

Posted: 30 Jan 2012 10:08 AM PST

Genetic mutations that boost an individual's adaptability have greater chances of getting through to X chromosomes -- at least in chimpanzees, according to new Danish research. An analysis of the genes of 12 chimpanzees has now demonstrated that the chimpanzee X chromosome plays a very special role in the animal's evolutionary development.

Targeted DNA vaccine using an electric pulse

Posted: 30 Jan 2012 06:36 AM PST

The vaccines of the future against infections, influenza and cancer can be administered using an electrical pulse and a specially-produced DNA code, new research suggests. The DNA code programs the body's own cells to produce a super-fast missile defense against the disease, researchers say.
