Sometimes, you need to start off your week with a dose of happy news. For instance, this video from the American Museum of Natural History details two recent instances where scientists have observed a whale and several dolphins interacting in ways that are something we might classify as "play".
It's hard to talk about animal behavior without getting too anthropomorphizing, but think about it this way: In both instances, the whale and dolphins did not appear to be competing with other, they did not appear to be fighting, nor were they cooperating in a goal-oriented way. When scientists say "animals are playing" they don't necessarily mean "play" the way human children play, but they do mean behaviors that go beyond simple eat/sleep/defend/breed necessities. Play might be learning. Play might be about forming social bonds that help an individual later on. And however you interpret it, spotting examples of spontaneous, inter-species play in the wild is kind of a big deal.
And now, with those caveats out of the way, I'd like to highlight the top comment on YouTube, by one Bill Kiernan: "We both used to be land animals, isn't that crazy? clearly we need to hang out."
I’ve had quite a few fun afternoons playing with dry ice from making spooky fog in the kitchen to exploding plastic bottles in the yard. But I’ve never had the opportunity to pour hot lava over dry ice. In this video, the lava is 1400 °C and the dry ice is -78C°. So cool! And […]
A Boston University team have developed an acoustic, 3D-printed metamaterial whose topology is such that it reflects 94% of human-audible sound; the researchers' demonstration involves inserting a ring of this stuff in a PVC pipe and blasting a speaker down one end: light and air emerges from the other end, but sound does not.
If you’re into tech at all, you should definitely consider unleashing your inner tinkerer on a Raspberry Pi board. If you’re intimidated, don’t be. It’s a statistical probability that people half your age have created cooler things than you can imagine with the versatile kit. Not sure where to start? The Complete Raspberry Pi 3B+ […]
Are you super organized? You’re going to love the Genius Pack G4 and its seemingly limitless, well-placed compartments. Not that organized? You’re still going to love this piece of luggage because it’s so well thought out that it practically does the packing for you. We’ve all tried to stuff a piece of carry-on so full […]
Despite government legislation and improving caller ID technology, robocalls and scam artists are rampant on the phone lines – up to 35 billion a year in the US alone. They can be annoying at best and a financial threat at worst, but there’s a way to take security into your own hands. One good example […]
