Research roundup: 6 cool stories we almost missed
摘要
每月总有引人入胜的科学故事因时间有限而未能详尽报道。本文精选了一月里几则几乎被遗漏的精彩研究，包括对口型机器人、以啤酒酵母作为实验室培育肉的支架、在达·芬奇画作中寻找其DNA，以及新证据表明巨石阵的石头确实是由人类从威尔士和苏格兰北部运输而来，而非冰川搬运。
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.

Stonehenge is an iconic landmark of endless fascination to tourists and researchers alike. There has been a lot of recent chemical analysis identifying where all the stones that make up the structure came from, revealing that many originated in quarries a significant distance away. So how were the stones transported to their current location?
