A major new study says that at least 65 species of animals laugh

[A major new study says that at least 65 species of animals laugh]( Laughter is one of the most natural impulses in humans. Most babies start to laugh out loud at around 3 to 4 months, far earlier than they are able to speak or walk. Expressing enjoyment or delight comes naturally to us, but we're not the only creatures who communicate with giggles. Researchers at UCLA have identified 65 species of animals who make "play vocalizations," or what we would consider laughter. Some of those vocalizations were already well documented—we've known for a while that apes and rats laugh—but others may come as a surprise. Along with a long list of primate species, domestic cows and dogs, foxes, seals, mongooses and three bird species are prone to laughter as well. (Many bird species can mimic human laughter, but that's not the same as making their own play vocalizations.) Primatologist and UCLA anthropology graduate student Sasha Winkler and UCLA professor of communication Greg Bryant shared their findings in an article in the journal Bioacoustics.

That goes for anatomy too. In this case, female anatomy. In a segment called “What Do You Know About The Female Body?” men try—and hilariously fail—to answer even the most basic questions, like “does a female have one uterus, or two?” much to the amazement of some of their female partners. Here are some of the very best bits of nonwisdom.

When he arrived, he saw a man getting into a car that matched the description he heard on the scanner. The deputy attempted to stop the man but he sped off, sparking a pursuit. The chase led the deputy to an intersection where he was involved in a crash with six other cars. Surveillance footage shows the deputy's car rocketing into a parking lot in front of a store. The police car was mangled, wedged between two other vehicles, and it caught fire. A man experiencing homelessness was at the scene and rushed to help. "I'm homeless. I was doing some work for someone. I was taking some tools back when I heard 'boom, boom, boom, boom, boom,'" Johnny Walker told ABC13. "I ran out here to see what it is and I saw a lot of cars, but I paid attention to the fire. My instincts were to go to that car and help him out, because he was crushed in on both sides."

Warren Davidson, a Republican from Ohio, sparked considerable outrage on Wednesday when he compared proof of vaccination cards to the Gesundheitspass, a health pass that Nazis demanded people carry during Hitler’s reign of terror. His tweet was a response to Washington, D.C.’s new mandate that anyone 12 and older will need to show proof of at least one vaccine shot before entering restaurants and other indoor venues. Davidson tweeted an image of a Gesundheitspass along with the caption, “This has been done before" as a response to a tweet about the mandate from D.C. Mayor Muriel Bowser. He then took things a step further by doubling down on his tweet with an explanation. "Let's recall that the Nazis dehumanized Jewish people before segregating them, segregated them before imprisoning them, imprisoned them before enslaving them, and enslaved them before massacring them," Davidson tweeted. "Dehumanizing and segregation are underway - and wrong."

However, one recent rescue has gone viral, after the team successfully found a pitbull who had been missing for nearly four months. Poor little Russ, a 3-year-old pitbull pup, had gotten spooked one night during a camping trip with his owner, Ricardo Rodriguez, in late August. Rodriguez had done his best to find Russ: getting the help of friends, calling local shelters, posting fliers. To no avail. And then, the Caldor Fire hit. As it destroyed several homes and businesses along a stretch of 200,000 acres, the flames forced an emergency evacuation for Rodriguez. From there, things began to turn bleak. "After months of not hearing back from anyone, I assumed he was in good hands with a different owner," Rodriguez told CNN. Luckily, Rodriguez and Russ’ story was far from over.
