Parts of arrows have been discovered at the Takashima underwater site in Matsuura, Nagasaki Prefecture, from a ship that sank during the Mongol invasions of Japan. The arrows, coated in black lacquer with red lacquer decoration, appear to be of Southern Song origin — suggesting the Mongols repurposed arrows seized after conquering the Southern Song for their assault on Japan.

The thread lit up with debate over how the find could even be confirmed as an arrow at all, alongside historical discussion of the power of Japanese longbows and Mongol military tactics — mixed in with some politically charged exchanges touching on China and Korea.

It was revealed on the 20th that parts of arrows have been found at the Takashima underwater site in Matsuura, Nagasaki Prefecture, from a ship that sank during the Mongol invasions of Japan in the Kamakura period, launched by the Yuan dynasty, which then held Mongol territory.

The arrows are believed to be from China’s Southern Song dynasty, seized by the Yuan after they conquered it and repurposed for the war against Japan.

Samsung Electronics’ Semiconductor (DS) division is paying out bonuses of up to roughly 60 million yen, while the smartphone and home appliance division is stuck at far lower levels — prompting labor unions to protest and demand better treatment. On the thread, opinions split between those arguing “it’s only natural to weight payouts toward the division that’s actually earning the money” and those countering “it doesn’t matter which division grinds to a halt, that’s a problem either way.” OECD data showing South Korea’s average wage now exceeds Japan’s was also brought up, spreading shock at the wage gap between the two countries.

Samsung Electronics is raking in massive profits from the AI boom, but cracks are starting to show within the organization. After handing out hefty bonuses to the semiconductor division, labor unions in other divisions are voicing objections. The huge profits are creating inequality that could undermine the “one big family” culture the company grew up on.

At the World Humanoid Robot Games in Beijing, China, a humanoid robot ran the 100m dash in 9.32 seconds, beating Usain Bolt’s world record of 9.58 seconds. However, after crossing the finish line it failed to decelerate in time, crashed into the safety mat, and caught fire — and on 5ch, the reactions focused less on the record itself and more on the “fiery finish” punchline, along with concerns about future military applications.

The theory that “corn can’t reproduce on its own, so aliens must have made it” sparked a thread on 5ch’s Science News+ board about the history of crop breeding. According to the article, corn’s actual ancestor is a closely related wild plant called “teosinte,” and starting around 7000–9000 BC, humans repeatedly selected individuals with larger kernels, eventually shaping it into the corn we know today. In response, commenters piled on with other examples of “plants that spread without producing seeds,” citing bananas, bread wheat, and Japanese narcissus.
