New gene linked to healthy aging in worms

People with the same lifespan do not necessarily have the same quality of life. As we live longer, extending quality of life—"healthspan"—is gaining importance. Scientists at the Okinawa Institute of Science and Technology ...

The spark that created life

Evolution by Darwinian natural selection is immensely powerful—both in nature and within laboratories. Using 'laboratory evolution', we can take an enzyme which combines random mutations and functional selection, and improve ...

Harmful genetic mutations may be less common than we thought

We are all mutants. Every characteristic that defines our species is the result of a genetic mutation somewhere in the history of evolution. And the same is true for every other organism on the planet. Yet more often than ...

In evolution, 'house of cards' model wins

Using sophisticated modeling of genomic data from diverse species, Yale researchers have answered a longstanding question about which competing model of evolution works best.

Darwin meets Newton: Evolution and the mass of the galaxy

If the solution to a problem does not reveal itself straight away then why not let your initial guesswork evolve? That's the approach we've taken in trying to determine the mass of our galaxy by mapping the historic movement ...

Should we teach creationism in schools? Yes, in history class

Despite lack of evidence or logic, some people would like kids to be taught as fact that the Earth was created by a supernatural being some 6,000 years ago. That is the case put forth by Christian Schools' Trust, as it was ...

Flexible throughout life by varying numbers of chromosome copies

Baker's yeast is a popular test organism in biology. Yeasts are able to duplicate single chromosomes reversibly and thereby adapt flexibly to environmental conditions. Scientists from the Luxembourg Centre for Systems Biomedicine ...
