Science Youtuber "Vsauce" (aka Michael) has his latest video up, talking about the scientific basis on why we go "awwwwww!" when we see a picture of a cute puppy, kitten or other soft and round object.
While I enjoy the scientific explanation, of course, it's also a chance to see some photos of cute babies, puppies and kittens.
If you want more cuteness, feel free to watch puppies live on YouTube.
