For thousands and thousands of years, adults couldn't digest dairy products without an upset stomach and a trip to the bathroom.

A few changes in our DNA gave about a third of the world's population – mostly Europeans — the ability to knock back cheese, pizza and chocolate ice cream without a care in the world.

Even the famed German automaker concedes that it "may resemble an old horse-drawn carriage."

But the recently rediscovered "first Porsche in the world" — dubbed the P1 — was a technological marvel for its time. It "included a compact electric drive weighing 286 pounds," writes the automotive news site Jalopnik, and could chug along at 22 mph.

On Jan. 9, people in and around Charleston, W.Va., began showing up at hospitals: They had nausea, eye infections and some were vomiting. It was later discovered that around 10,000 gallons of toxic chemicals had leaked into the Elk River, just upstream from a water treatment plant that serves 300,000 people.
