Costco doesn’t put signs in their stores to indicate where different things are, and it’s on purpose. This idea is to make you walk around the store more and see more things that you might end up buying.
Check out this tiny robot they made at MIT! They call it an origami robot, because it folds and unfolds by itself. Someone can swallow one and they can control it from outside with magnets. It can do some small kinds of surgery without any cutting.
Check out this GIF of some robotic fish. This has to be the most lifelike robot I’ve ever seen. I wouldn’t mind having some of these guys as pets. I’m sure they’re lower maintenance than the real thing.
I learned something really interesting about dogs today. Some scientists did some MRI scans on dogs to see how their brains responded to human voices. Apparently, the dogs’ brains responded to the voices in a similar way to humans’ brains. The scientists think that because dogs have lived alongside humans for so long, they have evolved to understand human emotions like happiness and sadness by listening to their voices. Here’s the full article if you’re interested, but it has a lot of scientific words in it:
“Dogs can tell when you’re laughing” means: dogs understand when you’re laughing.
