Being bitten by an Australian tiger snake is a wholly unpleasant experience. Within minutes, you start to feel pain in your neck and lower extremities -- symptoms that are soon followed by tingling sensations, numbness and profuse sweating. Breathing starts to become difficult, paralysis sets in, and if left untreated, you'll probably die. Remarkably, the venom responsible for these horrifying symptoms has remained the same for 10 million years -- the result of a fortuitous mutation that makes it practically impossible for evolution to find a counter-solution.

Cobras are renowned for their devastating flesh-eating venom, and the dramatic way they rear their heads upwards to flare their hoods. New research clarifies the purpose of these tactics and how they emerged among cobras -- insights that could help scientists develop more powerful anti-venoms, and help you spot an especially deadly cobra before it's too late.

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.

One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.
