All living whales are descended from terrestrial mammals, but how these aquatic creatures evolved into giant filter-feeders remains a biological mystery. New research shows that ancient whales had razor-sharp teeth similar to land-based carnivores -- an observation that's upsetting a prevailing idea that ancient whales used their teeth for filter feeding.

Researchers from Stanford's Hopkins Marine Station have developed a two-lensed camera that sticks to the backs of filter-feeding whales with suction cups. The new device has been used to capture unprecedented footage of whales in action, and it's offering new insights into the feeding and swimming behaviours of these aquatic beasts.
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.
