Biomedical engineers are helping develop a prosthetic arm for amputees that can move with the person’s thoughts and feel the sensation of touch via an array of electrodes implanted in the muscles of the patient.

Keven Walgamott had a good “feeling” about picking up the egg without crushing it. What seems simple for nearly everyone else can be more of a Herculean task for Walgamott, who lost his left hand and part of his arm in an electrical accident 17 years ago. But he was testing out the prototype of a high-tech prosthetic arm with fingers that not only can move, they can move with his thoughts...

The next solar cycle is predicted to take off within a year. In a pair of new papers, scientists paint a picture of how solar cycles suddenly die, potentially causing tsunamis of plasma to race through the Sun’s interior and trigger the birth of the next sunspot cycle only a few short weeks later.

The new findings provide insight into the mysterious timing...

Transformative biotechnology lets scientists build biological circuits that give cells unprecedented capabilities. A first-of-its-kind artificial protein – designed on a computer and synthesized in the lab – can be used to build brand-new biological circuits inside living cells. These circuits transform ordinary cells into smart cells that are endowed with remarkable abilities.

Medicine has a “Goldilocks” problem...

Researchers turned to biology to help in the design of next-generation computers. Moore’s law – which says the number of components that could be etched onto the surface of silicon wafer would double every two years – has been the subject of recent debate. The quicker pace of computing advancements in the past decade have led some experts to say Moore’s law, the brainchild of Intel co-founder Gordon Moore in the 1960s, no longer applies...
