The statement is one that most adults will, at some point, have made. They want to be alone.
The enteric nervous system contains hundreds of millions of neurons and communicates with the brain. It does not think independently or prove that emotions begin in the gut.
The Earth's magnetic field is, by every available measurement, the structural feature that protects the surface of the planet from most of the solar radiation that would otherwise sterilize it.
There is a particular fact about the most precise atomic clocks currently in operation that the wider cultural register has, on the available evidence, not yet adequately absorbed.
NASA's Ingenuity Mars Helicopter was designed to attempt up to five experimental test flights over thirty days.
