Brown University researchers used a special high-speed videocamera capable of recording 500 frames per second to capture the majestic leap of bull frogs. Viewing the video in super slow motion enabled them to study how frogs can jump more than ten times their length. From NatGeo:
Lead researcher Manny Azizi says a conclusion from the study is the frogs’ muscles have tremendous passive flexibility, unlike mammals, whose muscles are mostly ‘stiff.’ The frogs generate a ‘ton’ of mechanical energy during their jumps.
Azizi says the frogs are in some ways, “cheating the limits of what muscles alone should be capable of doing.”
The frog first stretches most of its hindlimb muscles while in a crouching position, making the muscles longer so they can produce much more force. That force is what propels them into the air.
Snail slime — called an epiphragm — is an incredibly strong yet reversible adhesive. Now, University of Pennsylvania scientists have developed a new kind of glue that employs the same mechanism as the epiphragm. The new material dries like superglue but once wet, it loses its adhesion. For years, scientists have explored adhesions inspired by […]
NASA released this incredible image of the sky that depicts 22 months of X-ray data captured from the International Space Station using the Neutron star Interior Composition Explorer (NICER). From NASA: “Even with minimal processing, this image reveals the Cygnus Loop, a supernova remnant about 90 light-years across and thought to be 5,000 to 8,000 […]
In the realm of rocket geeks and space nerds, filmmakers MaryLiz Bender and Ryan Chylinski have dream jobs. The pair have the equivalent of “backstage passes” to SpaceX, NASA and ULA rocket launches where they capture and share breathtaking videos that convey the power, risk, and thrill of space exploration. The work of their studio, […]
So you cut the cord and got rid of cable? Join the steadily growing club. But while you’re out picking a streaming service, you might find one big blind spot: Local TV and sports, not to mention first-run programming from the big cable networks. Luckily, there’s a throwback way to get it for free: The […]
Even if you feel like AirPods are worth the price tag, you’ve got to admit there’s a certain anxiety that comes with using them. What if I lose them? What if they get wet in the rain? Or drenched in sweat? Or fall into the drink you dropped them into? Shiny tech is great, but […]
With the quick-fix appeal of video games and their own cell phones, it can be tough to keep kids focused on supposedly “educational” toys. And while it may seem counter-intuitive to fight tech with more tech, we’re all in when it comes to the Toybox 3D Printer. We’re not sure if anyone had envisioned a […]
