Mice with artificial, 3-D printed ovaries have successfully given birth to healthy offspring.
It's another success for members of the same Northwestern University team that in March reproduced an entire menstrual cycle using organs-on-a-chip. This time, they've created ovaries from a type of gelatin hydrogel and infused them with immature egg cells before implanting them in female mice. The ovaries behaved like the natural ones, picking out an egg cell to mature and pass along, allowing t ...read more

Surprisingly, previous studies on this topic have been mixed, so these researchers performed a meta-analysis to get to the bottom of the matter. By systematically reviewing 18 studies on over 400 subjects, they found that yes, alcohol not on ...read more

In 2015, Canavero announced his intention to carry out the pioneering operation, with the head being that of a Russian man, Valery Spiridonov, who has a muscle degenerative disease. The source of the donor body was never specified. More recently, Canavero has said that a Chinese patient will be the first to have their head transplanted.
So who is Sergio Canavero, ...read more
