The researchers are building scaffolds that mimic the three dimensional structure of human tissue. They use a machine called a biofabricator to deposit cancer cells at strategic locations inside the 3D structures, just like tumors in human flesh. These structures are high fidelity test systems. Burg and her team can culture cancer cells in them, experimenting to see which treatments are the most effective, with the ultimate goal of personalizing a treatment or a vaccine for individual patients. Part of the National Science Foundation Series “Science Nation.”
The Curiosity Quest crew undertakes a stinky adventure at a water treatment facility. Find out what happens after flushing the toilet. Part of the Curiosity Quest Series.
Explains what a stroke is, types of strokes, warning signs, physical and mental effects of strokes, and risks for strokes. Presents information on the diagnosis and treatment of strokes and stresses the importance of early treatment. Stroke victims and their families share their experiences.
Monitoring water quality is vital to make sure dangerous bacteria doesn't creep into drinking water or overcome sewage treatment plants. With support from the National Science Foundation, engineers at the Monterey Bay Aquarium Research Institute have developed the Environment Sample Processor (ESP), a "DNA lab in a can." The size of a trash can, it can be placed in the open ocean or at water treatment facilities to identify potentially harmful bacteria, algae, larvae, and other microscopic organisms in the surrounding waters. It can monitor and send results back to the lab in real time to monitor water quality. Now, the engineers are modifying the ESP so it can go mobile, working from an autonomous underwater vehicle (AUV).
It was an email from a colleague that tipped off environmental engineer Detlef Knappe of possible 1,4-dioxane contamination in the Cape Fear River Basin, North Carolina’s largest watershed and a source of drinking water for communities across the state. The Environmental Protection Agency has classified 1,4-dioxane as a probable human carcinogen. With support from a National Science Foundation grant, Knappe and his team at North Carolina State University have begun to identify 1,4-dioxane sources and how 1,4-dioxane impacts drinking water quality. Knappe is also working with managers at water treatment plants and state policymakers in North Carolina to improve testing and treatment standards for 1,4-dioxane.

Nourish is an educational initiative designed to open a meaningful conversation about food and sustainability, particularly in schools and communities. In this clip, food experts discuss the treatment of animals in the industrialized food industry. Part of the Nourish Short Films Series.
When Brandon was 10 he was diagnosed with psoriasis. At first, he was very ashamed due to the visible patches on his skin. However, five years after his diagnosis, with adequate treatment, he lives with the disease and has a normal life.
Are you at risk for skin cancer? What are you doing to prevent it? How effective are sunscreens? Answers these questions and shows what melanoma can look like and how to spot it. Talks about the different types of skin cancer (basal cell carcinoma, squamous cell carcinoma, and melanoma) and treatment options. Discusses ways to maintain healthy skin.
Every year, a million babies are born worldwide with hereditary diseases. Physicians once had little to offer. Now a new breed of gene doctors is on the case. They are devising treatments that target the root causes of these diseases. Please note this title contains potentially offensive language.
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.
Known as one of the most remembered conquistadors of all time, Hernán Cortés conquered vast parts of Mexico for Spain. While Cortés brought about the end of the Aztec civilization, his legacy is marred by his brutal treatment of Mexican natives. Part of the "World Explorers" series.
What happens to water once it goes down the drain? Suzie shrinks Hanna and Olli so they can get a closer look. They travel through the sewers to the water treatment plant and learn what happens to dirty water. Part of "My Little Planet" series.
What are nuclear actin filaments? They are the tiniest first responders that help cells repair damage. Other features in this episode include interventions to help boost coral's resilience to bleaching and chips that help miniature drones navigate. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
Discussions related to sex education and prevention strategies may not be appropriate for this age group, so this simply provides a baseline of knowledge about HIV and AIDS. Covers the definition of HIV and AIDS, transmission, progression, treatment and the importance of treating HIV-positive people with respect and compassion. Presents information through a lens that emphasizes healthy decision-making.
NOVA takes an in-depth look at scientific breakthroughs in reproductive science. Discusses in vitro fertilization (IVF) and examines some of the latest techniques in treating infertility: cytoplasmic transfer, micromanipulation, and egg donation. Presents the challenges and risks of infertility and treatments. Raises ethical questions about the implications of reproductive technology.
In Bruce Logan's lab at Penn State University, researchers are working on developing microbial fuel cells (MFC) that can generate electricity while accomplishing wastewater treatment. In a project supported by NSF, they are researching methods to increase power generation from MFCs while at the same time recovering more of the energy as electricity. Through their research projects, Logan’s team has already proven that they can produce electricity from ordinary domestic wastewater.
Interviews with professionals and patients provide information on polluted air inside and outside, how it is caused, and what can be done about it. They also relate effects of breathing in polluted air, including asthma, emphysema, and chronic obstructive pulmonary disease and their treatments.
Iridium is a rare element used to light up cell phones and TVs. However, researchers have found a way to use a more common element to power electrical devices: copper. Researchers are also developing a better treatment for osteoarthritis through nanotechnology. Other segments include research into specialized metabolites and devices that translate sign language. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
Elisa Konofagou, a bioengineer at Columbia University, believes ultra sound technology could become be a vital component in treating and perhaps curing degenerative brain diseases. One big problem associated with treating these diseases today is a chemical shield of sorts that protects the brain against chemicals in the blood. Unfortunately, it also keeps out many drug treatments. Konofagou believes ultrasound waves could be one key to turning the blood/brain barrier on and off.
Imagine having the ability to manipulate light waves in order to see through a skull right into the brain, or being able to use lasers to diagnose a bacterial infection in a matter of minutes. At the Center for Biophotonic Sensors and Systems (CBSS) at Boston University, technologies enabling these abilities and many others are coming to light. With support from the National Science Foundation (NSF), mechanical engineer Thomas Bifano and his colleagues are developing optical microscopes that can image deep into biological tissue, helping scientists observe molecular-scale activity. Their goal is to revolutionize the diagnosis and treatment of disease. Part of the National Science Foundation Series “Science Nation.”
