Marine biologists in Hawaii investigate “super corals,” which thrive even as ocean temperatures rise. In this episode, the scientists reveal how corals create underwater cities bustling with life and explain how healthy and dying corals live side by side. Part of the "Super Corals" series.

In this episode, scientists try to uncover what makes 25 percent of individual corals tolerant of warmer water. Can these "super corals" be strategically planted to help reefs withstand climate change? Part of the "Super Corals" series.
In this episode, marine biologists take a close look at microscopic images of "super corals." The images reveal a dynamic interaction between colorful algae and the coral they inhabit. Part of the "Super Corals" series.
Corals have been devastated by the past few years of intense ocean heat. However, coral scientists are getting closer to understanding what makes certain species of coral able to withstand high temperatures. Part of the "Coral Comeback" series.
Symone Johnson, educator at National Aquarium, provides an overview of the series "Coral Comeback." She outlines coral reefs and discusses their importance to healthy ocean ecosystems. Part of the "Coral Comeback" series.
When the city is hit by a colossal snowstorm, only one superhero can save the day. But who is this mysterious hero, and why does he disappear once his job is done? Based on the children's book by Stephen Savage.
Who are the biggest super stars in the universe? For Adam Burrows, an astrophysics professor at Princeton University, it's not who, but "what," and they are far from Hollywood, or even Earth, for that matter. Burrows reveals that the biggest super stars are the stars that die in a massive explosion called a "supernova." With support from the National Science Foundation, Burrows investigates supernovae, and he has recently created 3D computer simulations showing the actual moment of a star's death. His simulations are revealing more about these stellar performances.
In Japan, researchers have created a super productive egg layer. The white leghorn hen has lost its instinct to parent due to selective breeding. They abandon the eggs that they lay so energy and time is not spent on caring for a chick. These hens are able to concentrate solely on laying eggs.
Corals are important ecosystem engineers, providing habitat and nutrient recycling to tropical reefs. However, coral species’ richness and abundance are in decline worldwide, due in large part to the impacts from global industrialization and human population growth. Coral disease is a major contributor to this decline of tropical reefs, and therefore, investigations into the causes of and remedies to these diseases are of critical importance.

More than 70 underwater canyons exist off the northeastern coast of the United States, and some are more than three miles deep. In this video, journey to some of the deep canyons and discover new species of sea coral through the eye of a remotely operated vehicle (ROV).
Societal change and growth is impacting the ocean ecosystem. One of these consequences is the rapid decline and death of coral reefs. Part of the "Coral Comeback" series.
For seven days in the Fall of 2012, Hurricane Sandy pounded the Caribbean and the East Coast of the United States with punishing rain, wind, and waves. What happened in the atmosphere that caused this monstrous storm to form? Summer and winter weather conditions collided with extreme forces to form a super storm. Part of the "Danger Zone" series.
Smart Puppy discusses the characteristics and mechanics of conductors. Part of the “Smart Puppy! and Friends” series.
For over a century, tens of millions of visitors have marveled at the natural beauty of Yellowstone National Park, home to the largest concentration of geysers in the world, including the iconic Old Faithful. Visitors may not realize it, but Yellowstone is situated directly above one of the largest volcanic systems on Earth-a supervolcano. For the past two million years, this volcano has erupted roughly every 600,000 years. The last major eruption, which produced a caldera that stretches over 1,500 square miles across the park-two-thirds the size of Prince Edward Island-occurred 640,000 years ago. So, is it overdue for another eruption?
Smart Puppy shows his friends when a magnet is not a magnet. Part of the “Smart Puppy! and Friends” series.
Marine biologist Chelsea Bennice discusses the amazing superpowers of the octopus. These sea creatures have incredible abilities and adaptations. They use camouflage, mimicry, and jet-power to outwit their predators. They also have the ability to learn new tricks to solve problems.
Preserving the environment and developing agricultural products that do not harm unintended targets are top priorities for many scientists and farmers. It’s a new era of crop management known as precision agriculture. It maximizes productivity while minimizing energy use and environmental impacts. One of the major challenges being addressed by precision agriculture is over-fertilization. Support from the National Science Foundation (NSF) has led to the development by startup SupraSensor Technologies of a novel sensor to detect nitrate fertilizer in soil. The SupraSensor device is designed to give farmers a highly accurate, virtually constant stream of data on nitrate levels. Part of the National Science Foundation Series “Science Nation.”
Find out the scoop on streamgages. What are they? How do they impact everyday life? Whether drinking from the tap, using electricity, or canoeing down a river, all of these activities benefit from information gathered by USGS streamgages.
With support from the National Science Foundation, Liangfang Zhang and his team at UC-San Diego have created a nanosponge to combat drug-resistant infections, such as those caused by Methicillin-resistant Staphylococcus aureus (MRSA). The nanosponge, made from biocompatible, biodegradable polymer nanoparticles, is camouflaged with a red blood cell membrane. It circulates in the bloodstream, absorbing the toxins produced by infection. Once the nanosponges are fully loaded with toxins, they are safely disposed of by the liver. They are designed to work with any type of infection or poison that attacks the cellular membrane. Part of the National Science Foundation Series “Science Nation.”
In 1928, a physician named Alexander Fleming observed that a mold in one of his Petri dishes was killing the bacteria he was trying to grow. This strain of mold led to one of the most significant medical discoveries in history: the antibiotic penicillin. Antibiotics soon became lifesavers. However, even back then, Fleming knew that bacteria could become resistant to penicillin. This video describes how widespread use of antibiotics in medicine, agriculture, and household products can lead to the evolution of microbes that are resistant to multiple antibiotics. Part of the "I Contain Multitudes" series.
