In this video excerpt from NOVA scienceNOW, find out how a paralyzed woman manipulates a robotic arm with her mind to successfully drink from a cup. Correspondent and New York Times technology columnist David Pogue explores this experiment conducted by the BrainGate research team of doctors, scientists, and engineers. BrainGate investigators explain the placement of a sensor on the brain of a stroke victim, how a person's arm moves, and how complex the brain's control of movement is. This resource is useful for introducing components of Engineering Design (ETS) from the Next Generation Science Standards (NGSS) to grade 6-12 students. This video is available in both English and Spanish audio, along with corresponding closed captions.

In this video from NOVA’s Sun Lab, learn about the Sun’s ever-changing surface and magnetic field. Images and animations illustrate how the Sun’s magnetic field lines are affected by the motion of the Sun’s plasma. Over time, the magnetic field becomes twisted and more complex, which increases solar
In this video from NOVA’s Sun Lab, learn about the Sun’s composition and structure. The Sun is a plasma, primarily made of hydrogen with smaller amounts of other elements. Animations and images illustrate the physical and behavioral properties of the Sun’s six regions: the core, radiative zone, conv
