Bumblebee Flight Does Not Violate the Laws of Physics
The reality is that bees and comparable insects fly in an incredibly complex way that utilises, get this, mini hurricanes! We’ll link all this stuff at the bottom in the references if you’re interesting in the nitty gritty physics, but in lay terms, bees fly by rotating their wings, which creates pockets of low air pressure, which in turn create small eddies above the bee’s wing which lift it into the air and, thus, grant it the ability to fly.

To find this out, scientists have conducted a vari...

Reimagining of Schrödinger’s cat breaks quantum mechanics — and stumps physicists
In a multi-‘cat’ experiment, the textbook interpretation of quantum theory seems to lead to contradictory pictures of reality, physicists claim.

Astronomers Have Found the Universe's Missing Matter
Now, in a series of three recent papers, astronomers have identified the final chunks of all the ordinary matter in the universe. (They are still deeply perplexed as to what makes up dark matter.) And despite the fact that it took so long to identify it all, researchers spotted it right where they had expected it to be all along: in extensive tendrils of hot gas that span the otherwise empty chasms between galaxies, more properly known as the warm-hot intergalactic medium, or WHIM.
