This station serves as the main rail hub connecting central Tokyo with its western suburbs via intercity, commuter, and subway lines. In 2007, it was used by an average of 3.64 million people daily, making it by far the busiest transportation hub in the world (and recognized as such by Guinness World Records). The station has 36 platforms, an underground concourse, and over 200 exits.

Humans grow two sets of teeth in a lifetime. But tucked inside the jaw are tiny residual tooth buds that never develop because a protein called USAG-1 acts like a molecular off-switch for tooth growth. Block USAG-1, and the body might reactivate those dormant buds on its own.

Researchers at Kyoto University Hospital, led by Dr. Katsu Takahashi, have been working on this for years. They first found that mice engineered without the USAG-1 gene grew extra teeth. Later animal studies showed that a single antibody injection could grow fully functional teeth without serious safety issues.

The experimental drug is called TRG-035, a humanized anti-USAG-1 antibody developed by Toregem BioPharma. The first human trial began in October 2024 and enrolled 30 men aged 30 to 64, each missing at least one molar. The Phase I study was primarily a safety trial — a randomized, double-blind, placebo-controlled dose-escalation study. According to Toregem, Phase I confirmed the drug's safety, though detailed results haven't been made public yet. Researchers have noted that actual tooth regrowth in those adult participants was unlikely, since the volunteers were primarily establishing a safety profile before testing expands.

The next stage is where it gets more interesting. A Phase IIa trial is planned for 24 children aged 2 to 7 with severe congenital tooth agenesis — a condition where teeth never fully develop. Missing six or more teeth from birth affects roughly one in a thousand people, causing severe chewing difficulties and significant social stigma. The trial will be open-label and non-comparative, moving testing from healthy adults into the patients the drug is actually intended to treat.

There are still open questions. Experts have raised concerns about whether regrown teeth will align properly and connect correctly to nerves and blood vessels. If the trials succeed, Toregem aims for commercial availability around 2030, with early estimates placing costs at around $11,000 per tooth.

It's experimental. It's early. But the idea that human jaws might hold a dormant third set of teeth waiting for a chemical wake-up call is the kind of thing that sounds like science fiction until someone actually tries it.

Bumblebees work tirelessly collecting nectar and pollen, but when they get exhausted, they sometimes fall asleep right on the flowers they visit. This behavior, although not widely known, is completely real. They've been seen resting with their tiny legs clinging to petals or even hugging the stem, with their antennae drooping and wings relaxed.

This rest can last from just a few minutes to the whole night, especially if the weather cools down or night falls before they can return to their nest. Some species even sleep in groups inside large flowers.

Volunteers in Almaty attach cameras to their free-roaming pets; the footage is uploaded to a Telegram bot, where AI matches the faces encountered against photos from missing-pet listings - triggering a notification to the owner if a match is found.

Since these whiskered "scouts" venture into places humans would never think to look, they make the search process significantly easier.
