Your Brain is a Construction Site: Neuroplasticity destroys the myth that your adult brain is hardwired. Every time you practice a skill or think a new thought, you are physically altering your brain’s structure.
Noble Gases Were Shy: The noble gases were called “inert” for so long because scientists couldn’t force them to react. It wasn’t until 1962 that Neil Bartlett tricked Xenon into making a compound.
The Naming of DNA: The word nucleic acid comes from the nucleus, where it was first found, but the acid part comes from its chemical nature. It’s actually a string of acidic sugar molecules holding the blueprint of life.
Nanotechnology Mimics Nature: A nanoparticle is not a human invention first. The tiny, self-cleaning hairs on a lotus leaf and the sticky feet of a gecko both use nanostructures perfected by evolution.
