Creepy or adorable? Researchers at Harvard University have demonstrated the first autonomous, untethered, entirely soft robot: the octobot.

Instead of being controlled by electronics, the robot’s logic board is powered by chemical reactions and fluid passing along tiny channels. Scientist have struggled to create completely soft robots because rigid components like circuit boards, power sources and electronic controls are difficult to replace.

So you know the cortical homunculus?

Ya know, this thing?

Well great news! Someone made one for raccoons and it is the greatest diagram I’ve ever seen in a science book!

We also got them for a few other animals too

I love how this post begins with “you know, the cortical homunculus” as if I’m supposed to know what the fresh hot fuck is going on here

We Finally Know How Birds Can See Earth’s Magnetic Field

myfrogcroaked:

A special eye protein is helping birds to “see” Earth’s magnetic field! If that’s not cool, I don’t know what is.

The ability to see Earth’s magnetic field, known as magnetoreception, relies on the presence of specifically the blue wavelength of light. The complex process involves “radical” intermediate molecules which are sensitive to Earth’s magnetic field. The Earth’s magnetic field, as it relates to the direction the bird is facing, could alter the intermediate radical molecules differently, giving the bird a sense for where it is facing in relation to the Earth’s magnetic field.

While the exact way birds visualize Earth’s magnetic field is part of further investigation, scientists believe the Cry4 protein acts as sort of a filter over the bird’s vision. This filter would allow birds to see a sort of compass of the Earth and direct their migratory flights accordingly.

A required read from Michael Oman-Reagan.

This is all true. This all happened in Canada, and its very likely it will happen in the USA under Trump and be worse than Harper’s crackdown on Science ever was.
