Honey Bees Can Understand the Concept of Zero

The concept of zero—less than one, nothing, nada—is deceptively complex. The first placeholder zero dates back to around 300 BCE, and the notion didn’t make its way to Western Europe until the 12th century. It takes children until preschool to wrap their brains around the concept. But scientists in Australia recently discovered a new animal capable of understanding zero: the honey bee. A 2018 study finds that the insects can be taught the concept of nothing.

A few other animals can understand zero, according to current research. Dolphins, parrots, and monkeys can all understand the difference between something and nothing, but honey bees are the first insects proven to be able to do it.

The 2018 study, published in the journal Science, finds that honey bees can rank quantities based on “greater than” and “less than,” and can understand that nothing is less than one.

The researchers trained bees to identify images in the lab that showed the fewest number of elements (in this case, dots). If they chose the image with the fewest circles from a set, they received sweetened water, whereas if they chose another image, they received bitter quinine.

Once the insects got that concept down, the researchers introduced another challenge: The bees had to choose between a blank image and one with dots on it. More than 60 percent of the time, the insects were successfully able to extrapolate that if they needed to choose the fewest dots between an image with a few dots and an image with no dots at all, no dots was the correct answer. They could grasp the concept that nothing can still be a numerical quantity.

It’s not entirely surprising that bees are capable of such feats of intelligence. We already know that they can count, teach each other skills, communicate via the “waggle dance,” and think abstractly. This is just more evidence that bees are strikingly intelligent creatures, despite the fact that their insect brains look nothing like our own.

Considering how far apart bees and primates are on the evolutionary tree, and how different their brains are from ours—they have fewer than 1 million neurons, while we have about 86 billion—this finding raises a lot of new questions about the neural basis of understanding numbers, and will no doubt lead to further research on how the brain processes concepts like zero.

This Rolling Smart Robot Will Keep Your Cat Company and Help It Exercise, Even When You’re Not Home

As any true ailurophile knows, cats love to sleep. On average, kitties spend anywhere from 16 to 20 hours of each day napping. But that laziness we often find so charming can sometimes lead to obesity, which can cause some pretty serious health problems for your feline friend. So how do you make sure your cat stays happy and healthy, even when you’re not home? That’s where Ebo comes (or rolls) in.

Ebo is a smart robot designed to keep your cat company and provide them with some much-needed stimulation, especially when you're not around. With more than $90,000 in pledges raised already, Ebo crushed its original $5110 Kickstarter goal, but you can still back the project here, with pledge tiers that start at $159 for a standard EBO and a smart collar that tracks your cat’s activity levels.

The Ebo itself, which is just over two inches tall, connects to Wi-Fi and features an app that allows you to schedule when you want it to start and stop playing with your cat.

When it’s playtime, the tiny robot scans the room to ensure there’s enough space to play safely. Once it makes sure the coast is clear, the robot moves on its own, utilizing an ergonomic design that enables it to wheel in any direction, spin, roll over, or even dance. You also don’t need to worry about keeping your cat’s robot friend charged. If your Ebo happens to be running low on battery, it rolls itself back to its charging station until it’s ready to go again.

According to the designers, Ebo interacts with cats in a way your feline friend understands—through a mix of sound, movement, and light that is always unpredictable. You can even play with your cat through the Ebo with its built-in laser.

The app also allows you to monitor your cat through video. And if they do something cute—as they always do—you can easily snap a photo or shoot a video, edit it, add fun filters, and then share it with others.

The device’s smart collar can be used for up to 30 days on a single charge. Should it get stuck, there’s a safety mode in which it will be released automatically to prevent accidental choking.

If you want an upgrade, there's the Ebo Pro (starting at $199), which features an AI algorithm that analyzes your cat’s mood and motion and adapts for future play.

No matter which Ebo you choose, they all come full of accessories, including decorative soldier, bamboo, onion, or feather caps. And if you order in time, you can snag a model decked out in a Santa hat.

Puppy Dropped By Predator Is a Purebred Australian Alpine Dingo, DNA Tests Reveal

A resident of Wandiligong, Victoria, Australia was surprised to find a small puppy in their yard last August after a bird of prey apparently dropped it there from the sky. A recent DNA test of the puppy adds a new twist to the story: As the Independent reports, the canine, which its rescuers initially assumed to be a baby dog or fox, is actually a purebred alpine dingo. Alpine dingoes are very rare and the only dingo subspecies in Australia that's at risk of extinction.

Wandi the dingo, named for the town in which he was discovered, was brought to the Alpine Animal Hospital after being found alone in a backyard with talon marks on his back. Veterinarians determined he was just 8 to 10 weeks old at the time he was found.

Suspecting that the rescue pup was a dingo, the hospital moved him to the Australian Dingo Foundation's sanctuary in central Victoria as they awaited DNA test results to confirm his exact type. There are three types of dingoes in Australia: tropical dingoes, inland dingoes, and alpine dingoes. Alpine dingoes are native to Australia's east coast, where most of the country's population lives, and the combination of habitat loss and the threat of humans has made them endangered.

The DNA analysis showed that not only is Wandi an alpine dingo, but he's a purebred. The majority of dingoes are mixed with domestic dogs, which makes it hard for conservationists to maintain the species's original gene pool. Now that they know his genetic background, the caretakers at the dingo sanctuary will consider Wandi as a candidate for their breeding program to help rebuild the vulnerable species.
