We summarize the week's scientific breakthroughs every Thursday.
- Health & Medicine
Sequencing virus genome to cure the common cold
The genomes of all known common cold viruses have been sequenced, providing new information on how the different strains are related, how they replicate and how to predict their virulence.

Darwin: The reluctant mathematician
Despite disliking mathematics, the great biologist inadvertently advanced statistics.
- Life
Duplication in genomes may separate humans from apes
A sudden peak in duplication of chunks of DNA in the common ancestor of humans, chimps and gorillas led to genetic flexibility, which created differences among the species.
- Climate
Winter birds shift north
More than 170 common North American species are wintering farther north than they did in the past.
- Life
Mother right whales know best, maybe
Southern right whales learn where to eat from mom and may not seek new feeding grounds if these favorite restaurants go belly-up.
- Life
Vertebrates, perhaps even humans, share teeth genes
Researchers have uncovered what may be a shared genetic toolkit for teeth, one common among vertebrates and mammals, including humans
- Ecosystems
Flowering plants welcome other life
When angiosperms diversified 100 million years ago, they opened new niches for ants, plants and frogs.
- Life
Molecular link between vitamin D deficiency and MS
Scientists have discovered a molecular link that may help explain why Vitamin D deficiency is associated with multiple sclerosis.
- Health & Medicine
Cancer fighting green tea may have a dark side
This herbal remedy can short-circuit one of the few useful therapies for largely incurable blood cancers.
- Genetics
Dog gene heeds call of the wild
Domesticated dogs passed a gene for dark fur color to their wild cousins.
- Life
Caterpillar noise tricks ants into service
Sneaky interlopers mimic the “voice” of an ant queen to get royal treatment from the colony. (Audio included.)
- Earth
Animal ancestors may have survived ‘snowball Earth’
Chemical fossils in Precambrian sedimentary rock push back the first date for animal life.
