Craftsmen in Serbia created capsule-style beehives that allow you to keep bees right in your apartment.

The system is completely sealed, so the insects cannot escape into the room; instead, they enter the hive through a tube that leads outside.

Yes: handwriting still matters.

A new study has confirmed that writing by hand activates far more complex and widespread neural networks in the brain than typing, underscoring its importance for learning and memory.

Researchers at the Norwegian University of Science and Technology used a high-density EEG cap with 256 electrodes to record brain activity in university students. They found that the intricate, sensory-rich movements involved in handwriting, especially cursive, trigger highly synchronized brain waves across extensive areas of the parietal and central regions. These coordinated patterns are strongly linked to memory formation, cognitive processing, and encoding new information.

In contrast, typing, which involves repetitive, simpler finger movements, produced significantly less neural connectivity and engagement. The difference was striking: the brain appears much less active during digital writing.

The researchers conclude that the unique motor and sensory experience of holding a pen plays a key role in brain development and learning. As a result, they argue that handwriting instruction should remain a core part of education to support deeper comprehension and cognitive growth in the next generation.

HEARTWARMING! A mother beluga whale escaped a marine research facility and swam hundreds of miles back to Alaska’s Cook Inlet.

Days later, she was spotted reunited with her calf.

Some bonds are simply too strong to break. ❤️

A massive boiling hole has suddenly opened up in Yellowstone National Park.

On June 13, a small hydrothermal explosion rocked Biscuit Basin, located less than 2 miles (3.2 km) northwest of the famous Old Faithful geyser. Fortunately, no one was injured—the area had already been closed to visitors since a much larger explosion damaged it in 2024.

What followed was a striking display of Yellowstone’s unpredictable power. Scientists detected unusual seismic activity and low-frequency rumbling near Black Diamond Pool. Shortly afterward, the Firehole River downstream turned a cloudy, milky gray.

Park cameras captured the moment: at around 5:09 a.m., a dark plume of steam and debris erupted from the ground just north of the pool. When geologists arrived, they discovered three new vent groups and a fresh crack in the earth, roughly 61 feet (18.5 meters) long and up to 5 feet (1.5 meters) wide, filled with near-boiling water at 194°F (90°C). Rocks had been violently ejected during the blast.

Then the site transformed again. Just days later, a new vigorously boiling pool had formed where solid ground once stood. Measuring about 21 by 17 feet (6.5 by 5.3 meters), the gray pool began shooting water 20 to 30 feet (6–9 meters) into the air.

This was not a volcanic eruption. Hydrothermal explosions occur when superheated underground water suddenly flashes into steam, causing a rapid and explosive expansion that can hurl water, mud, rocks, and debris skyward with almost no warning.

While Yellowstone is celebrated for its geysers, hot springs, and colorful thermal pools, these features are the visible signs of a restless underground system full of heat, water, and pressure. The latest event serves as a powerful reminder that the park’s most immediate hazards aren’t lava flows or a looming supervolcano, they’re the sudden, violent forces of boiling water and steam hidden just beneath the surface.

A man in 1835 was digging a duck pond and accidentally uncovered a 70-foot tunnel made of 2,000 sq ft of mosaic made from 4.6 million shells (mussels, cockles, whelks, limpets, oysters, scallops).

It's the Shell Grotto in Margate, Kent, England.
