Scientists have figured out why some miniaturized frogs from Brazil are such clumsy jumpers. A 2022 study published in Science Advances reveals that among adult vertebrates, members of the genus Brachycephalus have the smallest known semicircular canals – the part of the inner ear necessary for maintaining balance and spatial orientation.
The diminutive size of these canals results in low sensitivity to angular acceleration, preventing the frogs from controlling their posture as they prepare to land.

Science News Video: #mussels use their ‘beard’ to hang tight and let loose
In order to withstand the crashing waves, mussels have strong filaments called byssal threads to help them stick to rocky surfaces with surprising strength. When needed, the bivalves can also release these threads with seemingly little effort.

Researchers created a robot that uses advanced structural designs and a laser broiler to make this 3D printed cake hold its form. The robot can create and cook a cake with up to seven ingredients, more than any other printed food to date.

Evolutionary biologist Kurt Schwenk uses high-speed cameras to study the tongues of lizards. In slow motion you can see that in addition to being sticky, chameleon tongues can actually help them actually grasp their prey.

An unlikely automobile is bringing new meaning to the phrase “go fish.” Scientists put a fish tank on wheels to test whether goldfish (Carassius auratus) can navigate as well on land as they can in water. The goldfish go-cart uses the laser sensing technology lidar, an onboard camera, and motion detection software to track the fish’s location in the tank. When it swims toward a wall with its nose pointed outward, the vehicle rolls in the same direction.

You'd think that there are some features that, once an animal group evolved to have them, could never really go away, right? Well, Stefan is joined today by hosts from PBS Eons, Journey To The Microcosmos, and Bizarre Beasts to break down just how wrong that is! And yes, we will be talking about tardigrades.

Science News Video: Fool’s Gold Might Be Better Than the Real Thing
This month's Rocks Box is pyrite, also called fool's gold. But this fool's gold might not be so foolish, since we can use it to get all kinds of other minerals we really need, and it may be a key to getting real gold after all.
