Blood is one of the most revolutionary features in our evolutionary history. Over hundreds of millions of years, the way in which blood does its job has changed over and over again. As a result, we animals have our familiar red blood....

When it comes to creating vegetarian meat substitutes, flavor is only one hurdle—smell and texture are also major factors, and scientists have been making breakthroughs on creating a convincing meatless meat experience. We also got some...

What happens in your body after you get a bruise? Quick Questions explains!

No matter how much kale or spinach you eat, the bioavailability of non-heme iron doesn't increase, but the vitamin C in orange juice can actually help your body absorb more of it.

There are a lot of brightly colored fish in the world, but lingcod, which are usually brown and white, can sometimes end up quite blue, and not just on the outside.
