Mama Dolphins

We know by now that dolphins are super smart. Now we have found a new behaviour to prove their intelligence, and also adorableness: it seems pregnant dolphins sing to the unborn calves in their wombs. Cue the heart-eye emojis!

Tree Resuscitation 

Speaking of things in nature that are way smarter than we give them credit: trees! Trees are incredible, and here is one new incredible thing that they do: a near-dead tree stump can be kept alive by surrounding trees that send it water and nutrients through their underground root system.

Immigrants Are Good for Business

Despite what some very famous jerks like to say about immigrants, they are great for the economies of the countries they move to. Here's more evidence of this: 45% of Fortune 500 companies in the US were founded by immigrants and their children.

Crash Test Dummies Suck

Not the band - that's up to your own personal tastes. The actual crash test dummies, they suck. Or at least the female ones do. Women are 73% more likely to die in car accidents, in part because the female-shaped crash test dummy is 5 feet tall and weighs 110 pounds. This is not within the bounds of average female size.

Domestic Terrorism

The FBI has come out and said it: most domestic terrorism (in the United States) is caused by white supremacy.
