In this episode, Pele, the youngest female gorilla at Busch Gardens Tampa, is pregnant. But, near the end of her term, the animal care team discovers a dangerous situation developing with her baby. Witness the medical procedures that will hopefully save this baby’s life. Part of The Wildlife Docs series.
For centuries, silkworms have been breed to produce strong, fashionable silk threads. Today, the silk industry has joined forces with the biotechnology industry. Researchers are creating genetically modified worms which a produce a protein that aids in clotting blood. Researchers are looking to maybe one day use the protein in medical procedures.
Follows a family's unplanned Cesarean birth from early labor through recovery. An obstetrician explains the Cesarean procedure and discusses ways to minimize risk. Shows the surgical procedure using 3-D animation. Presents information on breast-feeding and recovery, and how to make a Cesarean birth a fulfilling experience. NOTE: Concludes with graphic footage of an actual Cesarean surgery.
A team visits a medical center to learn how medical equipment and procedures were developed for biomedical technology. They also discuss how biomedical technology is applied in medicine. Part of Invisible Science and Technology Surrounding Series.
Charles Drew set a standard of excellence unparalleled by most of his white contemporaries. In 1943, his distinction in his profession was recognized when he became the first black surgeon to serve as an examiner on the American Board of Surgery. Despite the prejudices of American society in the first half of the 20th century, Charles Drew persevered in his practice and was never afraid to stand up for his beliefs and racial equality.
In this episode, Mo Rocca explores a Medical MacGyver that makes health devices from toys, train spinning, computerized Smart Shopping Carts, and soda bottle lights.
Elephants can communicate over long distances using low-frequency sounds that travel both in the air and through the ground. Scientists are studying whether elephants can hear and interpret these ground vibrations. Using amplifiers, speakers, geophones, and video cameras, scientists have designed an experiment to test how elephant herds respond to an alarm call when it is played back through the ground.
Philanthropist Greg Carr describes his work reviving a national park in Mozambique, and his partnership with scientists at Princeton University. Biologist Rob Pringle, who conducts research in Gorongosa, explains what it means to think like a scientist in conservation biology. Part of the “Think Like a Scientist” series.
Humans construct boundaries around homes, neighborhoods, and nations to bring order to a chaotic world. However, they rarely consider how these boundaries affect the environment or others. Photographer Krista Schlyer and biologist Jon Beckman study how fabricated barriers influence the movement of wildlife. Schlyer and Beckmann have seen the damaging impacts resulting from the wall built along the Mexico-United States border. Humans probably will not stop constructing walls and fences any time soon, but planning the boundaries with wildlife in mind can help prevent these structures from causing environmental harm. Part of the "Think Like a Scientist" series.
Ants play important roles in many ecosystems, and a team of scientists are surveying ant populations in Gorongosa Park. Leading the study is Leeanne Alonso, she is cataloging the different species of ants in Gorongosa National Park and establishing a species census to monitor the ongoing recovery of the park.
Journalist Greg O'Brien reveals his struggle living with Alzheimer's disease, including the effects on his family. Harvard scientist, Rudy Tanzi, explains the mechanism by which this disease robs the identities of those affected. Tanzi also reveals current research into the treatment of the disease. Part of the “Think Like a Scientist” series.
The tragic 2013-2015 Ebola outbreak in West Africa shocked the world. Computational geneticist Pardis Sabeti and disease ecologist Lina Moses explain the science behind how this event became the largest Ebola outbreak in history. Part of the “Think Like a Scientist” series.
Dr. Jeffery Friedman introduces the genes and circuits that control appetite, including the key role of leptin. Part of the 2004 Howard Hughes Holiday Lecture Series.
Cyborg technology is a revolutionary development in rehabilitation medicine. It allows the brain and nervous system to manipulate specially engineered devices that help people regain the use of impaired body function. Once a dream of science fiction, this revolutionary technology is now becoming a reality. Demostrates a deep brain stimulation that can help stop the violent shaking of victims of Parkinson's disease. Presents two professors from the State University of New York and Duke University who discuss their cutting-edge research.
An important part of the conservation effort in Gorongosa National Park is to identify the species living in the park to ensure their protection and monitor their recovery. Every year, teams of scientists conduct biodiversity surveys in different areas of the park. Piotr Naskrecki leads a survey project in a particularly remote area, the limestone gorges of the Cheringoma Plateau, to study the bat population.
This animated short tells the story of Alfred Wegener, a German astronomer and atmospheric scientist, who came up with the idea that continents once formed a single landmass and had drifted apart. Continental drift explained why continents' shapes fit together like pieces of a puzzle and why distant continents had the same fossils. During Wegener’s time, the idea was met with hostility but after his death a large body of evidence showed that continents do indeed move. Today the theory of plate tectonics is a fundamental principle in geology.
Gene therapy is a method for treating inherited diseases by delivering corrective versions of genes to patients. Dr. Jean Bennett and Dr. Albert Maguire focused their careers on developing a successful gene therapy for an inherited form of childhood blindness called Leber congenital amaurosis (LCA). This documentary tells the story of how the LCA gene therapy was developed. Students will learn how autosomal recessive conditions are inherited, how scientists can use modified viruses to deliver human genes to cells, what makes the eye an ideal tissue for gene therapy, and how model organisms are used to test treatments before they are tested in patients.
The Darién Gap is a remote tropical forest that has been home to indigenous people for thousands of years. As pressures from outside human development encroach on the forest, these communities are protecting their land using a cutting-edge tool: drones. Through a partnership with a nonprofit organization, the Rainforest Foundation, they map their community boundaries to secure land titles, create sustainable land-use plans, and monitor their forests against logging and ranching.
Watch the story of how gene therapy restored the sight of a nearly-blind young patient. Told from the perspective of two researchers who spent over 25 years working to develop this breakthrough technology, this short film chronicles their successes and challenges, and illustrates how the method works to treat inherited conditions.
