In December 2020, a small landing capsule brought rock particles from the asteroid Ryugu to Earth — material from the beginnings of our solar system. The Japanese space probe Hayabusa 2 had collected the samples. Geoscientist Professor Frank Brenker and his team from Goethe University Frankfurt were among the first researchers wordwide allowed literally to “shed light” on these scientifically precious samples. In the process, they discovered areas with a massive accumulation of rare earths and unexpected structures...

A Northwestern Engineering research team has developed a 3-D printable ink that produces a synthetic bone implant that rapidly induces bone regeneration and growth. This hyperelastic “bone” material, whose shape can be easily customized, one day could be especially useful for the treatment of bone defects in children. Bone implantation surgery is never an easy process, but it is particularly painful and complicated for children. With both adults and children, often times bone is harvested from elsewhere in the body to replace the missing bone, which can lead to other complications and pain. Metallic implants are sometimes used, but this is not a permanent fix for growing children.
