what he can learn, see if he can pick up any business tips from P. And I can't tell you how this works out, but just I'll give you one hint: Asok the intern, it doesn't go well for him. That's all you need to know.

All right, next story. According to Oxford University Health, caffeine is linked to better vascular health. Oh yeah. If you're feeling stronger, it's because of me. You had an extra sip because you're watching this. You're a little bit heart healthier than you were a moment ago. That's called science.

Meanwhile, scientists at something called IFLScience are reporting that they gave rats some psilocybin, you know, magic mushrooms, and the rats became more optimistic. Now you might ask yourself, why do I want to make my rats more optimistic? And I think the obvious answer is, do you want sad rats? I mean, it's bad enough if you have a rat, but do you want a sad one? No, you want a happy one. So they give them mushrooms and make them happy. I think they're thinking there might be some connection to making humans happy, but I don't know. I think take the win. If you made some rats happy, that's not nothing. I like happy rats.

There's a new kind of 3D printing, according to Concordia University, that I don't understand exactly. But they call it holographic 3D printing, and it involves sound, using acoustic holograms. So in other words, somehow they can concentrate sound waves, and then the sound waves will be the force that puts the materials into its shape. But you know what's cool about it? Because it's sound waves, you could actually create something on the other side of a barrier. So you could actually 3D-create something inside somebody's body without opening them up. Now I guess you'd have to have some material that you got inside the body one way or the other, so maybe you have to open them up to put some 3D printing material in their body. But once it's in there, then they can put in the sound waves and actually turn it into something like a heart valve or some damn thing once it's already in your body.

Now I don't know if there'll ever be an application for that, but there is some thinking that this will completely change 3D printing. That'd be cool. That's getting a lot closer to the replicator in Star Trek, b
