Research roundup: 6 cool stories we almost missed
It's a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across each month. So every month, we highlight a handful of the best stories that nearly slipped through the cracks. January's list includes a lip-syncing robot; using brewer's yeast as scaffolding for lab-grown meat; hunting for Leonardo da Vinci's DNA in his art; and new evidence that humans really did transport the stones to build Stonehenge from Wales and northern Scotland, rather than being transported by glaciers.

So how were the stones transported to their current location?
