Silica is a key component of sand but also of lava. The less there is, the more fluid the lava, and the faster it flows. Nyiragongo has some of the lowest-silica-content-lava on the planet, but there’s another clue to the lava’s speed—and it’s not good news.

As the number of people who need organs goes up, the number of donors has plateaued, meaning we need to find new solutions. Dr. Doris Taylor and her team’s answer: custom-building organs from cadavers.

NOVA takes you inside the operating room to witness organ transplant teams transferring organs from donors to recipients. Meet families navigating both sides of a transplant, and researchers working to end the organ shortage. Their efforts to understand organ rejection, discover ways to keep organs alive outside the body, and even grow artificial organs with stem cells, could save countless lives.

Born with a damaged heart, two-week-old Harlow needs a transplant.

New fissures are devastating neighborhoods on Hawaii’s Big Island.

Under the right circumstances, your brain can trick you into experiencing some time intervals as longer than others. But under other circumstances, time itself really does slow down. The two phenomena—psychological and physical—are more similar than you might think.

A team of scientists recently discovered a large body of liquid water beneath the southern ice cap of Mars. The presence of liquid water, an essential ingredient for life as we know it, could help inform future studies for past and potentially extant life on the red planet. Explore the discovery made with radar technology and learn what scientists think about the potential of life on Mars.

On August 12, 2018, NASA launched the Parker Solar Probe to study the Sun like never before. It will hurtle towards the star at the center of our solar system at 120 miles per second, which is the fastest human-made object ever. The heat shield on the front of the probe will withstand temperatures of about 2500 degrees Fahrenheit to keep the instruments at roughly room temperature.
