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.
One of the weirdest places in Antarctica is Blood Falls, a five-story cascade of blood-red liquid pouring from Taylor Glacier. Researchers finally traced its source: a saltwater lake millions of years old trapped under the glacier.
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
