Upton flew on a Zero Gravity Corporation flight to model new bikini and one-piece fashions in weightlessness for Sports Illustrated's 2014 Swimsuit Issue, which hit newsstands today (Feb. 18).

The U.S. Food and Drug Administration (FDA) today allowed marketing of the DEKA Arm System, the first prosthetic arm that can perform multiple, simultaneous powered movements controlled by electrical signals from electromyogram (EMG) electrodes.
EMG electrodes detect electrical activity caused by the contraction of muscles close to where the prosthesis is attached. The electrodes send the electrical signals to a computer processor in the prosthesis that translates them to a specific movement or movements.
