Can an antibody blood test tell if you are immune to COVID-19? NOVA producer Caitlin Saks got the unusual opportunity to investigate her own blood to find out what exactly these “magic” molecules are, why public health professionals are eager to roll out antibody testing, and just what these antibody […]
Tackling climate change might seem daunting, but there’s actually a wide set of climate solutions. NOVA breaks down the three “speed bumps,” preventing, “undoing,” and adapting, that can slow and possibly stop us from reaching the worst outcomes of climate change. PRODUCTION CREDITS Narrated by: Caitlin Saks Produced by: Ari […]
Most experts agree that the key to avoiding worsening effects from a changing climate is to cut greenhouse gas emissions to zero, and through a strategy called “prevention,” humans can significantly cut emissions. Explore how scientists approach the challenge, and discover the technologies that will help get us there. PRODUCTION […]
It might be too late to prevent every climate-change-related catastrophic event from happening. But there is a way to reverse some of the damage from our emissions. Discover how geoengineering solutions — from techniques as natural as planting trees, to vacuuming CO2 out of the air, to science-fiction alternatives like […]
For many, the concept of “adapting” to climate change feels equivalent to admitting defeat. But climate change’s effects are already being felt today, so adapting will be necessary — and it doesn’t have to hurt. Explore how building resilience can have a silver lining. PRODUCTION CREDITS: Narrated by: Caitlin Saks […]
With an extraordinary new technology called CRISPR, we can now edit DNA—including human DNA. But how far should we go? Gene-editing promises to eliminate certain genetic disorders like sickle cell disease. But the applications quickly raise ethical questions. Is it wrong to engineer soldiers to feel no pain, or to […]
CRISPR gene-editing technology is advancing quickly. What can it do now—and in the future? The revolutionary gene-editing tool known as CRISPR can alter, add, and remove genes from the human genome. The implications are immense: It could help eliminate illnesses like sickle cell disease and muscular dystrophy, and could even […]
The gas phosphine, made on Earth by microbial life forms, was found in Venus’ atmosphere. Could this mean there’s life in our planetary neighbor’s clouds? Get the inside story from scientists Sara Seager and Clara Sousa-Silva on how the discovery was made, what it means, and what comes next. Produced […]
