(PhysOrg.com) -- Scientists in the US have solved the mystery about whether squid can hear and if so, how.
MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of generations.
