Telomelysin, a common-cold virus reprogrammed to destroy cancer cells, has won the world's first approval for esophageal cancer. It took 35 years, one surgeon's idea, and an Okayama University startup pushing through a regulatory maze.

For 15 years, donor cells vanished when grown across species. A Tokyo-Stanford team found why: the host embryo's first immune cells were eating them alive. The path to lab-grown organs, explained.

Japan's H3 Rocket No. 6 was postponed over poor weather and flew successfully on June 12, 2026. The booster-less test flight carried six small satellites: deorbit sails, a 1 km space tether, a day-and-night telescope, and a French sat that hunts ships gone dark. Here is what each one does.

Tohoku University spinoff Space Quarters has demonstrated its DAIQ orbital assembly robot system on a ground model, showing three kinds of small robots cooperating to pick, place, and weld building panels into a larger structure. We look at how it compares to NASA's cancelled OSAM-1 and DARPA's NOM4D, and what makes Japan's robotics approach distinct.

Shionogi has launched EndeavorRide, Japan's first prescription video game for childhood ADHD, covered by public health insurance. We unpack the Phase 3 results, the rise and fall of the US original EndeavorRx, and why a healthcare system can decide whether a game-as-medicine lives or dies.

Sony AI's autonomous robot Ace beat elite table tennis players and made the cover of Nature. From its Gran Turismo Sophy roots to the fast-ball wall that stumped DeepMind and a 20.2-millisecond reaction loop, here's how Sony's robot reached elite-competitive level in a real, physical sport.

Water beads up and rolls off a raincoat, so surely it slips along surfaces that repel it? A Kyushu University and University of Illinois team built a measurement 159 times more sensitive than before and found the opposite: water barely slips at all, regardless of wettability. Here's what that means for desalination and cooling tech.

Cold has killed living things since long before humans had fire. But what pulls the trigger inside the cell stayed murky. A Japanese team studying nematodes points to an unlikely suspect: copper.

A University of Tokyo-led team has produced the first high-precision genome of the Greenland shark, the longest-lived vertebrate. Changes in a linker histone and the ferritin gene offer the first real clues to its ~400-year lifespan, and to human aging.
