Gravity
From Discover Magazine, here's a great article all about gravity and how little we really do know. We've always thought gravity ended with Einstein. Everything kinda worked, and made sense. Or did it? We've had to invent dark matter, and other very interesting things to fill our universe to explain away observations. But what if we didn't really get gravity right in the first place? What if on really large scales, gravity acted ... well, not like we expected? What then? Well, this article collects some of the more interesting ideas. Check it out!
Inner Cow
This has got to be one of the most bizarre things I've ever seen. Researchers cut holes into the sides of cows and insert an cannula, which allows access to a live animals stomach. These holes are so big, you can actually see what's going on inside -- literally, reach into the stomach of a cow. Cows stomach have millions microbes that aid in digestion, and surprisingly, cannulated cows are usually the healthiest of the herd. You would think that walking around with a hole in your stomach would be bad for you, but apparently not. Some farmers apparently keep cannulated cows in their herd so they can serve as microbe donors to sick cows. Just bizarre. [Source: Oddity Central ]
