Using a new technique that is 10x faster than average MRI scanners, researchers at the Beckman Institute for Advanced Science and Technology show how the muscles in our neck, jaw, tongue, and lips work together to create sound.

The hollow mask illusion is a feat of optical witchcraft that tricks your brain into thinking that the inside of a rotating mask is exactly like the outside – a face with protruding features. Here, give it a try. We’ll wait.

That was awesome, right? It looks like a regular face, and then it turns out it was only the inside of the ma– wait, you’re saying it didn’t fool you for a second? Well … we don’t want to alarm you, but…

Collaborators from the Hannover Medical School in Germany and the UK’s UCL Institute of Cognitive Neuroscience found that there is a very specific subgroup of people who are totally immune to the cerebral fuckery of the hollow mask illusion: schizophrenics.

Scientists Discover Secret To Butterfly’s Invisible Wings 

An invisible butterfly might sound like something from a fairytale, but there are butterflies with wings as transparent as panes of glass.

The reason that their wings are transparent is because they barely reflect any light. A wide spectrum of light—from infrared to visible to ultraviolet—travels straight through the wing tissue. The property of the wing tissue that produces the butterfly’s transparency seems to go against nature’s instinct. The nanostructures on the surface of the butterfly’s wings are completely random, researchers report in Nature Communications. They seem to be scattered onto the wing surface with no regard for regular size or structured distribution.

Southern viscacha (Lagidium viscacia)

The southern viscacha is a species of rodent in the family Chinchillidae and is found in Argentina, Bolivia, Chile and Peru. It is a colonial animal living in small groups in rocky mountain areas. It has long ears and hind legs and resembles a rabbit in appearance apart from its long, bushy tail. The southern viscacha does not hibernate and is mostly active soon after dawn and again in the evening. At these times it emerges from its underground hiding place to feed on what plant material is available which is mostly grasses and moss, and it also eats lichens. Part of the day is spent perched on a rock sunbathing, grooming or resting.

Science offers the possibility of far greater well-being for the human race than has ever been known before. It offers this on certain conditions: abolition of war, even distribution of ultimate power, and limitation of the growth of population.

Why can radio and microwaves travel through space but sound can't?

Because sound waves are vibrational waves, while radio and microwaves are electromagnetic in nature.

Sound waves require a certain density of matter in order to travel and vibrate through. That’s why sound works on earth, but that doesn’t in space. There is an abundance of free molecules to vibrate through (molecules in the air). That’s how sound works by vibrating atoms and molecules.

But in space there are so little molecules available that sound waves cannot propagate.

Why electromagnetic waves can travel through space or a vacuum is more complicated and is a bit beyond my knowledge. But the gist of it is that, its because of wave particle duality and the fact that the particle involved is a photon. And photons do not require a medium to travel through.

If any physics people can elaborate or correct me, feel free.
