Initially, Clint Perry wanted to make a vending machine for bumblebees. He wanted to understand how they solve problems.

Perry, a cognitive biologist at Queen Mary University of London, is interested in testing the limits of animal intelligence.

"I want to know: How does the brain do stuff? How does it make decisions? How does it keep memory?" says Perry. And how big does a brain need to be in order to do all of those things?

About 3,000 years ago, a potter near Jerusalem made a big jar. It was meant to hold olive oil or wine or something else valuable enough to send to the king as a tax payment. The jar's handles were stamped with a royal seal, and the pot went into the kiln.

Over the next 600 years, despite wars destructive enough to raze cities, potters in the area kept making ceramic tax jars, each one stamped with whatever seal represented the ruler du jour.

They didn't know it, but in the process, the ancient potters were not just upholding centuries of tax bureaucracy.

Each year, fish farms produce a massive amount of carp — so much that if you put all that fish on one side of a scale, and all the people living in the U.S. on the other side, they'd pretty much balance each other out by weight.

But for the past couple of decades, carp have been plagued by a type of herpes virus, known as Koi herpesvirus.

In the foothills of Colorado's Rocky Mountains, a gravel road leads to a 10-foot-tall fence. Type in a key code, and a gate scrapes open. Undo a chain to get behind another. Everything here is made of metal, because the residents of this facility are experts at invasion and destruction.

By the time Kay Schwister got her diagnosis last summer, she couldn't talk anymore. But she could still scowl, and scowl she did.

After weeks of decline and no clue what was causing it, doctors had told Schwister — a 53-year-old vocational rehab counselor and mother of two from Chicago — that she had an incurable disease called Creutzfeldt-Jakob disease, or CJD.

The disease was shrinking Kay's brain, and riddling it with holes. She would likely live only a few more weeks, the doctors said.

Scientists have described a new kind of sea creature in what's now central China. It lived 540 million years ago, and the tiny, baggy organism could occupy a peripheral spot on our own evolutionary tree.

When scientists like Simon Conway Morris discover a new animal, they get to name it. He and his colleagues in China don't seem to give compliments where they aren't deserved.

A group of scientists is gathering this week in the U.K. to discuss a slab of ice that's cracking in Antarctica. The crack could soon split off a frozen chunk the size of Delaware.

One glacier scientist, Heidi Sevestre, spent six weeks last year living on that giant slab of ice off the Antarctic Peninsula.

Right now, a big chunk of Antarctic ice is hanging on by a frozen thread.

British researchers monitoring the crack in the Larsen C ice shelf say that only about 12 miles now connect the chunk of ice to the rest of the continent.

People think of black holes as nightmare vacuum cleaners, sucking in everything in reach, from light to stars to Matthew McConaughey in the movie Interstellar. But, in real life, black holes don't consume everything that they draw in.

In 2015, Lida Xing was visiting a market in northern Myanmar when a salesman brought out a piece of amber about the size of a pink rubber eraser. Inside, he could see a couple of ancient ants and a fuzzy brown tuft that the salesman said was a plant.

As soon as Xing saw it, he knew it wasn't a plant. It was the delicate, feathered tail of a tiny dinosaur.
