Spaceflight is not for the faint of heart — literally. The first results of NASA's twin study, released just this week, revealed that space physically impacts astronauts on multiple levels, right down to shifts in gene expression. Now, a group of scientists at the University of Michigan have released research that suggests spaceflight alters astronauts' brains.

A team of Australian and US scientists have, for the first time, used an imaging technique to reconstruct the brain architecture and neural networks of the thylacine – better known as the Tasmanian tiger – an extinct carnivorous marsupial native to Tasmania.

And now we know more than ever about the behaviour of these unique animals.

Neuroscienitsts have generally thought that babies are born with more tissue than their brains need, and that the body slowly dumps some of it as the brain develops. However, a new study shows that at least one part of the brain — the part that recognises faces — appears to develop in the opposite direction, increasing in complexity into adulthood.

A University of Adelaide-led project has overturned the theory that the evolution of human intelligence was simply related to the size of the brain — but rather linked more closely to the supply of blood to the brain.

The idea that humans might one day become superintelligent — or invent a superintelligent computer — is a staple of science fiction. It's also taken seriously by scientists and engineers as a plausible outcome of today's technologies. Here are ten key books you should read to understand brains of the future.

Humans have asked where we come from for thousands of years, across all cultures. But only recently have we started to address the mystery of the evolution of the human brain — the organ that's the source of those existential questions, not to mention our evolutionary success itself.
