How computers can now interpret what someone is seeing just from their brain activity - could we "see" dreams in the future? Oil extracted from used coffee grounds can be used to make a better smelling biodiesel; chimps recognise faces in the same way we do; proteins found to located specific DNA sequences very effectively; and the ethical issues surrounding the use of robots for care and war. Plus, in 'Stuff and Non-Science', are meteorites hot when they hit the ground?
