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.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

A Wily Fox With a Passion for Fashion Stole More Than 100 Shoes From a Berlin Neighborhood

In Berlin, Germany, a fox has embarked on a crime spree that puts Dora the Explorer’s Swiper completely to shame.

CNN-News18 reports that residents of Zehlendorf, a locality in southeastern Berlin, spent weeks scratching their heads as shoes continued to disappear from their stoops and patios overnight. After posting about the mystery on a neighborhood watch site and reading accounts from various bewildered barefooters, a local named Christian Meyer began to think the thief might be a fox.

He was right. Meyer caught sight of the roguish robber with a mouthful of flip-flop and followed him to a field, where he found more than 100 stolen shoes. The fox appears to have an affinity for Crocs, but the cache also contained sandals, sneakers, a pair of rubber boots, and one black ballet flat, among other footwear. Unfortunately, according to BBC News, Meyer’s own vanished running shoe was nowhere to be seen.

Foxes are known for their playfulness, and it’s not uncommon for one to trot off with an item left unattended in a yard. Birmingham & Black Country Wildlife explains that foxes are drawn to “things that smell good,” which, to a fox, includes dog toys, balls, gardening gloves, and worn shoes. And if your former cat’s backyard gravesite is suddenly empty one day, you can probably blame a fox for that, too; they bury their own food to eat later, so a deceased pet is basically a free meal.

The fate of Zehlendorf’s furriest burglar remains unclear, but The Cut’s Amanda Arnold has a radical idea: that the residents simply let the fox keep what is obviously a well-curated collection.
