Over 1800 rhesus macaques inhabit the tiny island of Cayo Santiago just off the east coast of Puerto Rico. Most of these monkeys managed to survive Hurricane Maria, but researchers speculate that their behavior and cognition may have been altered. The reason is a change in availability of resources on the island, including that of shade.

Follow the race to rebuild the Old Blenheim Bridge in New York State, an icon of 19th century American engineering, destroyed by Hurricane Irene in 2011. Watch a team of elite craftsmen faithfully reproduce the massive, intricate wooden structure under grueling time pressure as flooding threatens their worksite.

A team scrambles to move a bridge across a rapidly rising creek.

Explore Nyamuragira, one of the world’s most active and mysterious volcanoes in Africa. Decades of civil strife have prevented scientists from investigating the volcano, but a brief pause allows an international team of experts to fly by helicopter to the summit to investigate. Discover the volcano’s hidden dangers, and probe whether magma pressure is building up to threaten another eruption.

Climb with volcano experts to the summit of Nyiragongo, a highly active volcano in the Democratic Republic of the Congo. Twice in recent memory it has erupted, devastating Goma, a neighboring city of 1 million people. To investigate when it might erupt next, scientists climb into its crater toward a bubbling lava lake to deploy sensors and monitor the volcano’s activity.

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.

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

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.

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.

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.

Remembering John Pilley, the owner and trainer of Chaser the Border Collie.

When it comes to generating power, shining light on silicon opens up many possibilities.

Could pieces of plastic garbage become the resource we need to construct buildings?

Much of a diamond's brilliance and fire comes down to physics.

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.

Explore the science of grilling and how it could affect your health.

What the Physics?! is about the physics in you, of you, and around you.

Thanks to physics, no memory can last forever.
