This video excerpt from NOVA examines the promise and realities of developing drugs designed to treat genetic disorders. The video presents the story of one patient, Michael McCarrick, whose lungs were devastated from years of suffering from cystic fibrosis. After researchers identified the gene involved in cystic fibrosis, it took decades to find ways to fortify the faulty protein responsible for the serious illness. Kalydeco, one of the first drugs to treat the underlying cause of cystic fibrosis, offers patients hope that they will not have to endure a lung transplant. 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
