Scientists produce embryos in race to save northern white rhino from extinction

Scientists working to save the northern white rhino from extinction have produced two more embryos of the world's most endangered mammal, increasing the number of viable embryos produced so far to five. There are no known living males and neither of the two remaining northern white rhinos on Earth - a mother and her daughter living in Kenya - can carry a calf to term.

Lobster shell patterns make concrete stronger: Australian researcher

Inspired by the natural, twisting patterns of a lobster shell, Australian researchers say they have found a way, using 3D printing technology, to improve the strength of concrete for use in complex architecture. Reinforced with steel fibres, the concrete becomes more durable when set in a pattern that copies a lobster shell, according to a new study from Melbourne's RMIT University.

Need a lift? SpaceX launches record spacecraft in cosmic rideshare program

Scientists in Greece find 20 million year-old petrified tree

Greek scientists on the volcanic island of Lesbos say they have found a rare fossilized tree whose branches and roots are still intact after 20 million years. The tree was found during roadwork near an ancient forest petrified millions of years ago on the eastern Mediterranean island and transported from the site using a special splint and metal platform.
