A low-cost sequencing technique advances us closer to the goal of the $1000 human genome.
On page 1663 of this week's issue of Science and in last week's Science Express, two teams independently report that changes in regulatory DNA were responsible for an adaptation in natural populations of fish and insects. Each group has also pieced together details of the underlying genetic alterations in those animals.
The promise of genomics has been luring ecologists into the once-alien world of molecular biology.
Two papers from a prominent chemistry lab were retracted from Science and the Journal of the American Chemical Society this fall because the results couldn't be replicated. The story behind the retractions involves an extortion attempt and a threat of suicide.
A male sterility protein localizes to evolutionarily dynamic loci within heterochromatin and leads to their decondensation.
Genetic analyses of Asian peoples suggest that the continent was populated through a single migration event.
This week, ScienceNOW reported that weight gain may result from a loss of genes; why firstborns don't share; monkeys may use grammar; and a quasar that built a galaxy, among other stories.
