Using Math to Explain How Life on Earth Began
Published October 6, 2008, 9:33 pm, Scientific American
Back in March the press went crazy for Martin A. Nowak’s study on the value of punishment. A Harvard University mathematician and biologist, Nowak had signed up some 100 students to play a computer game in which they used dimes to punish and reward one another. The popular belief was that costly punishment would promote cooperation between two equals, but Nowak and his colleagues proved the ...

First Glimpse Of A Key DNA Repair Protein At Work
Published October 4, 2008, 7:07 am, Medical News Today
Repairing breaks in the two strands of the DNA double helix is critical for avoiding cancer. In humans and other organisms, a molecular machine called the MRN complex is responsible for finding and signaling double-strand breaks (DSBs), then launching the error-free method of DNA repair called homologous recombination.

- Human evolution coming to a halt - Yahoo! News UK: «Mutation rate was also slowing down, he said. Although chemicals and radioactive pollution could cause genetic changes, one of the most important mutation triggers was advanced age in men. 'Perhaps surprisingly, the age of reproduction has gone down ? the mean age of male reproduction means that most conceive no children after the age of 35,' said Prof Jones. 'Fewer older fathers means that if anything, mutation is going down.'»
- Leading geneticist Steve Jones says human evolution is over - Times Online: Speaking today at a UCL lecture entitled ?Human evolution is over? Professor Jones will argue that there were three components to evolution ? natural selection, mutation and random change. ?Quite unexpectedly, we have dropped the human mutation rate because of a change in reproductive patterns,? Professor Jones told The Times.
