Antonio Paris translates how to survive on other planets into surviving after Maria.

The spinning of the Earth means we don't always see straight paths as straight.

After Hurricane Maria, the Arecibo Observatory and its staff worked to rebuild its facility––home to the most powerful astronomical radar and one of the largest radio telescopes on Earth––and aid the neighboring community.

Ben Francis became addicted to opioid painkillers in high school after a soccer injury. Today, he helps others struggling with addiction through an opiate epidemic task force.

In her teens, Casey stayed busy with sports. But severe muscle cramps landed her in the hospital, where she was prescribed opioids for her pain. An emergency room doctor realized she was addicted and said not to come back—leaving her and her family to deal with the problem on their own.

Supervised injection sites—like the one in Vancouver, Canada—offer people a safer place to use, often helping those with a long history of addiction who don’t respond to oral treatments like methadone and Suboxone.

Therapist Cindy Chamberlin works with children at high risk of physical and developmental delays, through an innovative program called Birth to Three. Its goal is to intervene early to help children develop the skills they need.

Hear firsthand from individuals struggling with addiction and follow the cutting-edge work of doctors and scientists as they investigate why addiction is not a moral failing, but a chronic, treatable medical condition. Easy access to drugs like heroin, fentanyl, and even prescription medications like OxyContin has fueled an epidemic of addiction—the deadliest in U.S. history.

Nearly 20 million Americans are struggling with addiction, yet over 90% of them will not receive treatment, in large part due to the stigma surrounding the disease. One way to destigmatize addiction is to change the language that we use to describe it, starting now.

After crushing his leg in a mining accident, West Virginia resident Jasen Edwards was prescribed painkillers. He became addicted––and lost his job and marriage as a result. But today, Jasen’s on the road to recovery.

Puerto Ricans are innovating to find new energy solutions after the storm revealed extreme weaknesses in the island’s electrical grid.

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.
