The complex structure of the basic functional unit of an ovary, the follicle, can now be reproduced using 3D printing. The development by researchers at Northwestern University has been proved with 3D-printed ovaries in mice, raising the hope that the same can be done for women whose ovaries have been damaged, allowing them to bear children.

A grand total of 756 hours of engineering time and dozens of bad jumps went into Jaguar's debut stunt for its new E-Pace SUV, which in the end managed to perform a flawless barrel roll. Driver Terry Grant, who had to perform with only a 10-millimeter margin of error, said it's the first time a production car has pulled off such a feat.

From impossible to possible appears to be the theme for researcher Jingyuan Qu at Germany's Karlsruhe Institute of Technology, who has created an object that contracts when heated and now has developed a cube the expands under pressure. The trick involves the cube's drumlike hollows, which have surfaces that depress like a drumhead but rotate levers to drive the cube's overall expansion.
