What if your ‘lizard brain’ never existed? Scientists challenge a 70-year-old theory and uncover the wiring battle that may have shaped human intelligence
Scientists reconstructed a Wyoming forest from 56-million-year-old fossil leaves; it lost about 60% of its canopy during ancient warming and took more than 100,000 years to recover
Scientists uncovered a bizarre crocodile cousin from 215 million years ago that started life walking on all fours, then changed its entire stance as it grew — by adulthood it was standing upright and striding around on two legs
Scientists looked inside a rock pellet smaller than a grain of rice and found a 445-million-year-old world preserved within it — more than 20 microscopic marine organisms, including a species never seen before
Life on Earth may have begun twice. A Science Advances study found that bacteria and archaea inherited one ancient genetic code but independently evolved the machinery needed to become free-living cells — leading the researchers to describe it as “one origin of the genetic code, but two origins of life.
Scientists have found an ancient sea worm with jaws made from a mysterious 'bio-metal' never encountered before, a discovery that could rewrite what we know about nature
Science news this week: Gold tongues discovered in tombs, sugar found in space, a new monkey identified in the Congolian rainforest, and ancient impact crater 'geoguessed' by an amateur astronomer
