Ancient humans didn’t need braces. So why do we?

Just watched this https://www.youtube.com/watch?v=0HlLwG2xN_c about #MarineBiology and how they're using ocean water samples, extracting DNA fragment from animal waste in it- all to find if a speacies of sea creature is present... All without having to dive or observe directly!

That's absolutely fucking wild. Even more wild? Apparently we've only discovered 10% of the sea creatures. Nature is so cool. #Biology

Help needed: im trying to grow some Wolffia duckweed, and the enclosure i have made for them has been hit by something. It appears in the water as white fuzz, and appears to grow between the duckweed, tying them together. I droppered some of it onto a slide, and put it under the microscope. It came out as this fiber. Is it a cyanobacteria? Is it harming my plants? If it is a group of cyanobacteria, they will go away once the duckweed thoroughly shades the surface.

🧠🍦 Brain freeze is a protective reflex triggered by the rapid cooling and warming of blood vessels in the roof of the mouth.

The trigeminal nerve carries these pain signals to a central cluster where the #brain misinterprets the location as the forehead. The temporary sensation is the body's way of maintaining a consistent internal temperature for the brain.

🧬🤖 Developmental biologists used #frog embryo cells to create neurobots that possess primitive neural networks. These self-organized systems allow the biological #robots to exhibit more complex movement patterns than previous versions.

The #research helps scientists understand how different cell types coordinate to build complex structures and behaviors.
