Scientists now say there are at least 2 trillion galaxies in the observable universe, more than 10 times previous estimates.
DNA from old skeletons suggests a complex history of new DNA being introduced.
RIGGED!!! | Sam Bee's Election Report. Rock Group Drive-By Truckers Take on the South. All The Things Mike Pence Said Donald Trump Didn’t Say, He Did. The Secret US Prisons You've Never Heard of Before. Do Cause and Effect Really Exist?
Why there's no such thing as cause and effect at the level of fundamental particle physics, and how our everyday experience of cause and effect arises due to entropy and the large-scale arrow of time
Extreme weather events are nothing new, but they appear to be gaining strength. Scientists have risked life and limb to help us better understand—and better survive—these storms
These laws explicitly remove patient protections. Doctors recommending right-to-try can’t be sued for malpractice or disciplined by their state medical boards, seemingly no matter how inappropriate or incompetently executed such a request might be.

Why entropy gives rise to the arrow of time, how the initial state of the universe is responsible for the fact that we experience time now, and the ultimate heat death of the universe.
Computer scientists can prove certain programs to be error-free with the same certainty that mathematicians prove theorems. The advances are being used to secure everything from unmanned drones to the internet. However, they're not claiming they are going to prove an entire system is correct, 100 percent reliable in every bit, down to the circuit level. "That’s ridiculous to make those claims."
Just like taxonomists have debated over which physical characteristics warrant a new species designation, they’re conflicted over how much genetic variation you need to prove differentiation.
