Frog tongue mechanism has been well-documented, but only recently have scientists started looking at the remarkable combo of tongue softness and frog spit's chemical makeup.
For the frog, the mix of a super soft tongue and non-newtonian spit is why their prey sticks so well. The tongue pushes against the saliva as it hits its prey, applying a shear force to the liquid as it spreads. This makes the saliva runny, pouring into every bump and crevice of the frog’s prey. But as the pressure drops, the saliva returns to a thick, gooey and elastic state, helping it grip onto the prey hard enough to withstand the crazy g-forces of being launched into the frog’s mouth.
More than 125 of these curious soccer ball-sized glass spheres hang near the floor of the Mediterranean Sea. Even though they’re deep underwater, they’re keeping a constant vigil for neutrinos, particles that may be evidence of dark matter, supernovae, and neutron stars far off in intergalactic space. Eventually, the Cubic Kilometer Neutrino Telescope (KM3NeT) will […]
A key challenge in building colonies on the moon is that it’s incredibly expensive to transport construction materials to space from Earth. That’s why researchers are exploring how moon bases could be mostly constructed from raw materials already there. A team of scientists working with the European Space Agency (ESA) are exploring how urine could […]
The new Mars rover Perseverance, set to launch in July for a February 2021 landing, will be outfitted with its own small helicopter. NASA engineers at Kennedy Space Station recently put the chopper through its paces, marking the last time they’ll spin it up before landing on the red planet. From Kennedy Space Center: The […]
There are few things more satisfying than the clickety-clack of an old keyboard. So old, in fact, that it’s really more of a typewriter sound and feel than that of a keyboard. But if you want to enjoy the benefits of both, check out this Rymek Retro Bluetooth 3.0 Mechanical Keyboard. Bringing you an impressive […]
There are plenty of productive ways to spend time while stuck indoors. While it’s undoubtedly fun to binge all 15 seasons of Supernatural or sink days of playtime into an Overwatch campaign, learning something new is definitely a more meaningful and long-term beneficial use of open hours. And if you’re going to invest time in […]
If you’ve ever had any musical aspirations — or even if your talent extends no further than turning on the radio — you’ve probably dreamed the “impossible” dream. You dream that maybe you could record some of your songs at home, post them online, build an armada of fan support, attract major label attention and […]
