Ancient teeth bacteria record disease evolution

DNA preserved in calcified bacteria on the teeth of ancient human skeletons has shed light on the health consequences of the evolving diet and behaviour from the Stone Age to the modern day.

Method identifies mutations that drive genetic diseases

(PhysOrg.com) -- For the first time, a new computational method allows researchers to identify which specific molecular mechanisms are altered by genetic mutations in proteins that lead to disease. And they can apply this ...

New insights into the effects of radiation from Chernobyl

Researchers at the University of Stirling have found that animals in lakes closest to the Chernobyl nuclear reactor have more genetic mutations than those from further away, giving new insight into the effect of radiation ...

Parasitic plants use stolen genes to make them better parasites

Some parasitic plants steal genetic material from their host plants and use the stolen genes to more effectively siphon off the host's nutrients. A new study led by researchers at Penn State and Virginia Tech reveals that ...

Long-lived parents produce better quality offspring

Genetic manipulation that more than doubles lifespan also leads to better offspring—according to new collaborative research from the University of East Anglia and Uppsala University.

Resurrected mammoth blood very cool (w/ Video)

(PhysOrg.com) -- A team of international researchers has brought the primary component of mammoth blood back to life using ancient DNA preserved in bones from Siberian specimens 25,000 to 43,000 years old.

Asexual reproduction leads to harmful genetic mutations

A team led by biologists at The University of Texas at Arlington has published a study supporting the theory that species that reproduce asexually have more harmful genetic mutations than those utilizing sexual reproduction.
