There, scientists can make casts, or reproductions, of the bones and try to recreate the complete skeleton. Scientists can learn a lot from this process: The way the bones fit together gives a basic idea of the dinosaur's shape and posture. Flat, leaf-shaped teeth mean that the dinosaur ...
Fish rise and sink in water primarily using a swim bladder, which they inflate or deflate with oxygen to adjust their buoyancy. The swim bladder's volume changes allow the fish to displace different amounts of water, balancing the forces of buoyancy and gravity. Some fish, like sharks and ...
the most jaw dropping features of the prosthetic, its ability to feel objects in its grasp. when the prosthesis make contact with the object, there are sensors in the fingertips, and then the brain of the prosthesis has also a neuro stimulator, which delivers electrical pulses to the nerves....
Our lungs are the organs that allow us to breathe. When we breathe in—or inhale—our lungs fill with air which contains oxygen. When we breathe out—or exhale—a gas called carbon dioxide flows out of our lungs. We continue our quest to explore with our hands as we make a model of ...

layered ChR2-expressing cardiomyocytes in a serpentine pattern on a ray fish-shaped elastomer with a gold skeleton—to retract to the original shape, in an attempt to create prototypes for organ bioengineering. Photoactivation triggered sequential muscular contractions, creating undulatory photo...
re at Disneyland. You want to meet the one and only Mickey Mouse, but there’s no clear way to make it happen. You rely on Character Guides, those daily printed sheets that point you in Mickey’s general direction. But let’s be honest, it was like finding a needle in a haystack....
