Scorpion’s sting evolved from insects’ defensive proteins
With a single genetic mutation, an insect’s defensive proteins can be transformed into a toxin that gives scorpions their signature sting, a new study shows.

Microbe and human genes influence stomach cancer risk
When genes of the bacterium and its human host evolve together, the strain is less harmful than that same strain in a person whose ancestors didn't encounter that particular microbe.

Elephant shark genome small and slow to evolve
The animals have the smallest genome of non-bony fishes and the slowest-evolving genes among vertebrates, a study suggests.

All mice are the same, until they’re not
A new study shows substantial differences in how two closely related mouse strains respond to drugs. It offers new options for linking genes and behavior and may change how scientists think about the similarity of their mouse strains.

You are what your dad ate, perhaps
Your development is affected by what your mother ate while she was pregnant with you. Is it also affected by what your father ate? A new study suggests that folate deficiency in dads can affect their offspring through epigenetic changes.
