  • Roaches: How They Get Clean


    Cockroaches are constantly grooming themselves, says entomologist Coby Schal of North Carolina State University. To clean its antenna, a cockroach will grab ahold of it with its front leg, bring the antenna to its mouth, and run the antenna from base to tip through its mandibles like a piece of floss. Publishing in the Proceedings of the National Academy of Sciences, Schal and colleagues investigate the benefits of clean antennae.

    Breakthrough: Polar Bear Witness


    For USGS wildlife biologist Karyn Rode, tracking and tranquilizing polar bears from a helicopter are just the first thrilling steps in her research. After acquiring various samples from sleeping bears, Dr. Rode's unique understanding of what they eat and how quickly they metabolize nutrients allows her to determine the condition of each bear. Working with a team of scientists from the US Fish and Wildlife Service for nearly a decade, Dr. Rode's monitoring of polar bear health has helped reveal how well populations are adapting to the rapidly warming Arctic.

    *Correction May 1, 2017: At 2:06, a graphic in the video incorrectly wrote the formula for the golden ratio. It should be B/A = A/(A+B). We regret the error.

    John Edmark's sculptures are both mesmerizing and mathematical. Using meticulously crafted platforms, patterns, and layers, Edmark's art explores the seemingly magical properties that are present in spiral geometries. In his most recent body of work, Edmark creates a series of animating “blooms” that endlessly unfold and animate as they spin beneath a strobe light.

  • Rap Nerdy To Me


    MC Frontalot, aka Damian Hess, makes a living rapping about data encryption, rare diseases, video games and the nerd life. When we stopped by his Brooklyn apartment, Frontalot described Nerdcore, his name for the genre, as the inversion of the shame of geekery... into pride. Dr. Awkward, a California-based nerdcore rapper, says that people assume nerd rap is a joke: But it's not really about the juxtaposition of those two worlds -- nerdiness and hip-hop -- it just happens to be nerds expressing themselves through hip-hop.

    MC Frontalot joins Science Friday (3//1):

  • What Can Frogs See That We Cant?


    Check out the original double slit experiment: - oh, and for the sun to be seen as single photons, you would have to be ~1000 light years away, so well past Pluto. For clarification on this video, please see:
    What would you see if you were drifting through space, looking back at the sun? Well its light intensity would decrease as the inverse square of distance from the sun. And you would imagine the intensity would decrease smoothly, asymptotically approaching zero.

    But this is not what happens.

    If you had sensitive enough eyes, like frogs' eyes, you would find that at some point the sun would start to flicker. You would see flashes of light separated by complete darkness. And as you drift further from the sun, what's strange is that these flashes do not decrease in brightness, but they do become less frequent. That's because light comes in lumps, called quanta or photons, which are indivisible. So if you try to spread light out very thinly, you reach a point where there are only single bits of light reaching an observer's eye at any given time.

    I should acknowledge the book The Fabric of Reality by David Deutsch, which contains a similar story about a frog and a torch. It inspired me to make this film. Thanks also to MinutePhysics for reviewing earlier drafts and suggesting I make it more ridiculous.

  • 2012 - LENR - Low-Energy Nuclear Reactions - ITN Truthloader


    More Info on LENR:

    This is a three minute video about Low-Energy Nuclear Reactions (LENRs). Sam Datta-Paulin of ITN Truthloader reports on Nov. 30, 2012.

    It's a complicated subject and they got most of it correct. They correctly report there has been a significant uptick in the interest lately and LENRs do have the potential to change the world. And yes, it is the same field of study, but it has nothing to with fusion, as they correctly note. There's only two facts that Truthloader didn't present accurately.

    Andrea Rossi has claimed many things. But when they say that Rossi's claimed power plant unit sold to a major anonymous U.S. customer widely reported to be DARPA, Truthloader missed the truth. No credible source has reported this rumor and it is not true.

    Second correction: NASA has never held any demonstrations of any LENR devices, let alone a device like Rossi's which, as he inadvertently revealed to me on camera, shows to be fake. The Sept. 2011, NASA Glenn meeting was a discussion only.

The researchers filmed fish and digitized their movement to try to answer the question.

    As a choreographer who often collaborates with dancers with disabilities, Merry Lynn Morris has long thought that traditional manual and power wheelchair designs were constraining. Her work in integrative dance, along with her experience growing up with a father who relied on a wheelchair, inspired her to invent a power wheelchair designed for artistic expression. Equipped with omnidirectional movement, a rotating seat, and a hands-free control, the chair enables dancers to explore new movement techniques, and may one day provide greater mobility in everyday life, too.
