Archimedes once famously said “give me a place to stand, and I shall move the Earth.” This wasn’t some bogus philosophical statement. The ancient physicist was just trying to illustrate a simple, but highly effective machine: the lever. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. Every lever consists of three main components:

This year we celebrate a century since Albert Einstein’s posited his most famous equation: E=mc2. But what does it mean? How does it affect me? These are all highly pertinent questions, and luckily Symmetry Magazine put together an amazing video that puts all this to rest, and while fitting anti-potatoes and the Higgs boson in the same picture. Wait till you see it.

For bacteria, it’s a dog eat dog world, as you can see below; in this video, a bacteria called Myxococcus xanthus is devouring Escherichia coli, another bacteria. Myxococcus xanthus is a gram-negative, rod-shaped species of bacteria. They are a predatory species, working as a single biofilm called a swarm. The colony is also called a “wolf pack”, and can reach several inches wide.
