• What Moves Us

    ·

    The idea that the universe is made of tiny vibrating strings was once the science theory du jour. String theory promised to unite the disparate theories describing particles and gravity, and many people, not just scientists, were optimistic that a theory of everything might be within our grasp. But here we are, many years later, and string theory doesn’t seem to have delivered on its initial promise. What happened? We consider the science around string theory in this episode of Skeptic Check.

  • How Bad Does It Have to Get?

    “Climate change at warp speed” is the way one scientist described the coronavirus outbreak.   In a show recorded before a live audience at the Seattle AAAS meeting, and co-presented with the BBC World Service, we discuss out how politics and psychology lead people to tune out inconvenient scientific findings even… Listen ⇢

  • It’s In Material

    Astronauts are made of the “right stuff,” but what about their spacesuits?   NASA’s pressurized and helmeted onesies are remarkable, but they need updating if we’re to boldly go into deep space.   Suiting up on Mars requires more manual flexibility, for example.  Find out what innovative materials might be used to… Listen ⇢

  • Skeptic Check: Pandemic Fear

    Contagion aside, coronavirus is a powerful little virus.  It has prompted a global experiment in behavior modification: elbow bumps instead of handshakes, hand sanitizer and mask shortages, a gyrating stock market.   Pragmatism motivates our behavior toward the spread of this virus, but so do fear and panic. In 1918,… Listen ⇢

    Skeptic Check: Pandemic Fear
  • Climate Changed

    Have you adapted to the changing climate? Rising waters, more destructive wildfires, record-breaking heatwaves. Scientists have long predicted these events, but reporting on climate change has moved from prediction to description. There’s no time for dwelling on “we should haves.” Communities and organizations are being forced to adapt. Find out… Listen ⇢

  • Frogs’ Pants

    It’s one of the most bizarre biological experiments ever. In the 18th century, a scientist fitted a pair of tailor-made briefs on a male frog to determine the animal’s contribution to reproduction.  The process of gestation was a mystery and scientists had some odd-ball theories.   Today, a 5th grader… Listen ⇢

  • Perpetual Emotion Machine

    Get ready for compassionate computers that feel your pain, share your joy, and generally get where you’re coming from.  Computers that can tell by your voice whether you’re pumped up or feeling down, or sense changes in heart rate, skin, or muscle tension to determine your mood.  Empathetic electronics that… Listen ⇢

  • Your Brain’s Reins

    You are your brain.  But what happens when your brain changes for the worse – either by physical injury or experience?  Are you still responsible for your actions? We hear how the case of a New York man charged with murder was one of the first to introduce neuroscience as… Listen ⇢

    Your Brain’s Reins
  • Shell on Earth

    (repeat)  We all may retreat to our protective shells, but evolution has perfected the calcite variety to give some critters permanent defense against predators.  So why did squids and octopuses lose their shells?  Find out what these cephalopods gained by giving up the shell game. Plus why Chesapeake Bay oyster… Listen ⇢

  • Yule Like This

    (repeat)  Fir tree needles embedded in carpet are a holiday headache.  Why not decorate a genetically-modified, needle-retaining tree instead?  It’s just another way that science is relevant to the holidays.  We have more. How about science experiments on fruitcake?  There’s a competition that includes launching it with a pneumatic device,… Listen ⇢
