Do Crows hold funerals? Nah, not really, but they're up to something when one among the murder is murdered, and scientists are fascinated by their behavior around fallen comrades.
Calling to each other, gathering around, and paying special attention to a fallen comrade is common among the highly intelligent corvids, a group of birds that includes crows, jays, magpies, and ravens, says Kaeli Swift, a Ph.D student in environmental science at the University of Washington. (See "Are Crows Smarter Than Children?")
But it doesn't necessarily mean the birds are mourning for their lost buddy. Rather, they're likely trying to find out if there's a threat where the death occurred, so they can avoid it in the future.
One study involved using masks to see if crows would avoid humans who handled dead crows (and thereby implicated themselves in the investigation.) They did. On the other hand, if crows are smart enough to investigate murders, maybe they're smart enough to take one look at that mask and think: "OK, that is definitely a murderer."
These two little bear cubs are play-fighting, but they look beary serious.
The poop of King Penguins releases high levels of nitrous oxide, aka laughing gas. An international team of researchers from China, Denmark, and the UK were studying how the retreat of glaciers and penguins activity impact soil greenhouse gases on South Georgia, an island north of Antarctica. They observed that the penguin guano is rich […]
Will dogs obey commands from robots? In IEEE Spectrum, Evan Ackerman writes that “Yale University’s Social Robotics Lab led by Brian Scassellati presented a paper taking the first step towards determining whether dogs, which are incredibly good at understanding social behaviors in humans, see human-ish robots as agents—or more specifically, whether dogs see robots more […]
You may not realize it, but one of the fastest-growing employee benefits over the past several years is one that’s keeping thousands of workers feeling happier and healthier. Back in 2013, only 13 percent of employers were willing to provide or subsidize standing desks for their workers, but by 2019, that number had exploded to […]
First, they were all about serving a protective necessary function. But now, about 10 weeks after the explosion of the COVID-19 outbreak, face masks are beginning to serve a different role. Just like all the fashion accessories that came before them, face masks are now showing off a little piece of ourselves to the everyday […]
Promoting products is almost nothing like it was back in the Mad Men days. In fact, the digital landscape has changed the ad game so much that it barely even resembles early Grey’s Anatomy days anymore. Marketing a product digitally isn’t about the right ad slogan or color scheme. It’s about crafting the narrative around […]
