Need an Implant? Just Print It Out
Patients who need a life-saving implant may soon be able to get a customized one from a 3D printer. In the first procedure of its kind, surgeons replaced the sternum and a portion of the rib cage with a 3D-printed titanium sternum and rib implant. The procedure, performed in a 54-year-old Spanish man with a chest wall sarcoma, was reported in a recent issue of the European Journal of Cardio-Thoracic Surgery.
Single Mutations Can Alter Ecosystems to Same Extent as Species Loss

A study in Nature Communications now shows that microevolution — small changes within a single population — is an equally important yet hitherto overlooked shaper of multi-species communities.
