Scientists at UMass Amherst taught an AI to count bees and tell honeybees from bumblebees just by listening to their buzz, so they don't need traps that harm bees.

A tiny microphone hidden in a tomato plant. A fuzzy, orange-striped bumblebee grabs a yellow flower and shakes its flying muscles so fast that the pollen pops out like salt from a salt shaker. On a computer nearby, the AI writes: "Bumblebee. Shake-the-flower buzz." Every bee flies home safe.

It listened, guessed, checked the answer, got a score, adjusted, and tried again, like learning to ride a bike. It trained on 594 recordings made over 5 years at 43 sites. When it was very sure, it was right about 93 to 97 times out of 100. It is a coach with super patient ears, not a replacement for scientists.

1. With a grown-up, sit near some flowers (or anywhere outside).
2. Close your eyes and listen for one minute.
3. Guess what made each sound: bee, bird, car, wind?
4. Open your eyes, check, keep score, and try again.

Never touch or chase a bee; watch from a few steps away. Too cold for bees? Play indoors: a family member makes sounds (crinkling paper, tapping a spoon, pouring water) while you guess with your eyes closed.

A volcano baked a scroll into charcoal almost 2,000 years ago, and it's been too fragile to unroll ever since. On October 8, 2026, the Vesuvius Challenge awarded its $50,000 First Letters Prize to Erwin Nieuwlaar, a software engineer from the Netherlands. He found the first readable letters ever seen inside that scroll, PHerc. 343. It's about 14 cm long and kept at the Biblioteca Nazionale di Napoli in Naples, Italy.

Here's how he did it:

• He traced one layer of the rolled papyrus inside an X-ray scan, using the challenge's open-source spiral-fitter plus his own way of snapping it tightly to the surface.

• He ran four AI ink-detection models (one is named Hecate) and averaged their answers. None of the models had been trained on this scroll, so they were "generalising across scrolls."

• Papyrologists, who are experts in reading ancient papyrus, read the Greek letters as part of the phrase "everything that happens."

• Other teams found the letters μουσικ (mousik), which may point to a word about music.

A burnt black "marshmallow log" a little shorter than a pencil. Deep inside it, glowing yellow letters light up on a computer screen without anyone unrolling a single layer. Erwin shouted, in Dutch, "Dit is toch gewoon inkt!" ("This is surely just ink!").

The ink detectives practiced like you learning to ride a bike. They made a guess ("ink here, no ink there"), got a score, adjusted, and tried again, thousands of times. They practiced on other scrolls and still recognized ink in this new one, the way you can ride at the park after learning in the driveway.

The AI pointed and said "look here." Erwin did the tracing and the thinking, and human experts did the reading. People and AI worked as a team.

1. Write a secret message on white paper with a white crayon. Press hard.

2. Roll it up and trade with a friend or family member.

3. The ink detective brushes watercolor paint over the paper, and the hidden letters appear.

4. Bonus (with a grown-up): ask an AI helper, "What clues could help a detective tell ink apart from paper?" and brainstorm together.

Pavel Rabtsevich, a hobby astronomer in Spain who doesn't own a telescope, used AI coding helpers to search public data from NASA's TESS space telescope, and found a faraway star that dims a tiny bit about every three days. That could mean a planet is passing in front of it. He checked his AI helpers' work round after round, and now TESS will look at the star again from October 31 to November 26 to test his predictions.

A star 116 light-years away blinking like a clock (dim, three days, dim, three days), in measurements taken years apart, and nobody had noticed until now.

Be a planet hunter at home. With a grown-up, shine a flashlight at a wall in a dark room (never into anyone's eyes) and slowly move a small ball through the beam. Watch the light on the wall dim as your "planet" passes its "star." Try a bigger ball to see if it dims more. Then predict your planet's schedule ("it passes every three claps") and have someone check you.

This is a planet candidate, not a confirmed planet. Rabtsevich says himself that more observations are needed, and that even if the star dims on time in November, that alone won't prove it's a planet.
