Pigs were domesticated from wild boars about 9,000 years ago. Researchers have long assumed that this process involved permanently isolating a few animals from the wild. But according to new findings published in Nature Genetics this week, pig domestication doesn’t follow this traditional model: Pigs continued to mate with wild boars even after they became domesticated.

Ankylosaurs were heavily armored herbivorous dinosaurs with bony plates all along their wide backs. They were the tanks of their time, and some even carried a giant club at the end of their tail. Researchers studying the tail clubs of these later “weaponized” forms found that the stiff handle evolved first, and the knob followed. The findings were published in the Journal of Anatomy.

Researchers have found the building blocks of life deep below the seafloor, adding evidence to the theory that life is able to spring up wherever there is water, and of course the right chemistry. The study, published in the Proceedings of the National Academy of Sciences, could have implications for the chances of life existing on other worlds, such as Jupiter’s moon Europa.

It's official: Claw machines are rigged. But we all pretty much assumed that anyway, right? Like a lot of fairground and arcade games, the odds are ever in the house's favor. They're not games of skill, but simply pot luck.
But... that doesn't stop us from trying anyway.
Take a look at this video by VOX and YouTube user Matt3756 explaining how the claw machine makers rig the machines to make a solid profit off your frustration and stubbornness.
