NOVA: Season 48

Season 48 overview

The opening episodes examine genetic-data privacy, chemical reactions, the molecular conditions for life, and persistent inequalities in science. These subjects frame scientific discovery alongside questions about its social consequences.

Key story beats

  1. DNA Data and Privacy — The episode examines the value of DNA testing and the risks of placing private genetic data in commercial enterprises and online databases.
  2. Chemistry of Reactions — David Pogue explores chemical reactions, including processes involved in making cement and feeding a global population, as well as the chemistry of high explosives.
  3. Making Science More Inclusive — The episode addresses the low representation of women, especially women of color, in STEM and researchers' efforts to expose discrimination and improve inclusion.
  4. Molecules Behind Life — David Pogue investigates photosynthesis, ozone, Rubisco, and molecules associated with life's beginnings and development on Earth.
  5. Mars Rover Search — NASA lands a car-sized rover in an ancient Martian river delta to search for traces of life, store samples for possible return, and test technology relevant to future human travel.
  6. Discrimination in Science — The episode revisits underrepresentation in STEM and follows efforts to expose longstanding discrimination and make science more inclusive.
  7. Saving Coral Reefs — Marine biologists respond to bleaching and reef decline amid ocean heat waves, attempting assisted evolution through heat-resistant coral crosses and algae transplants.
  8. Journeys Through Infertility — The episode follows people facing fertility challenges and considers structural inequality, racism, falling sperm counts, egg freezing, and IVF.
  9. Reinvestigating the Hindenburg — Newly discovered footage prompts a renewed investigation into the cause of the Hindenburg disaster.
  10. Electric Aircraft Challenges — The episode surveys electric aircraft prototypes, including short-haul craft and test-flight air taxis, and raises the significant hurdles facing wider adoption.
  11. Clues from a Shipwreck — Excavation of a rare, intact wreck off Sweden offers new clues about the ship-design innovation that enabled long-distance ocean voyages during the Age of Exploration.
  12. Decoding Bat Biology — Scientists investigate bat biology and possible connections to longer, healthier lives, while the episode notes bats' association with deadly epidemics.
  13. Evidence on Cannabis — The episode weighs scientific evidence about cannabis's possible benefits and risks and examines the disproportionate harm criminalization has caused communities of color.
  14. Hunting for Neutrinos — An international team attempts to detect a fourth form of neutrino, a result that could challenge the Standard Model and alter understanding of the universe.
  15. Arctic Research Drift — Scientists from more than twenty nations conduct long-term research from the icebound Polarstern during a year-long Arctic drift, facing dangerous ice, cold, and polar bears.
