Are these like public randomness beacons? NIST[0] and Cloudflare[1] have them. I guess use cases are lotteries that are publicly verifiable, election auditing...

ajay-d··on Japan and South Korea see surge of suicides among young women
The male increase looks more in line with the prior year fluctuations. The female increase is way more pronounced. Though I think universally, male suicide count is always higher, regardless of country.

ajay-d··on How Can a Star Be Older Than the Universe?
GN-z11 is a galaxy that's 32 billion light years away. Here's the note from wikipedia:

At first glance, the distance of 32 billion light-years (9.8 billion parsecs) might seem impossibly far away in a Universe that is only 13.8 billion (short scale) years old, where a light-year is the distance light travels in a year, and where nothing can travel faster than the speed of light. However, because of the expansion of the universe, the distance of 2.66 billion light-years between GN-z11 and the Milky Way at the time when the light was emitted increased by a factor of (z+1)=12.1 to a distance of 32.2 billion light-years during the 13.4 billion years it has taken the light to reach us.

Russia also recruits cyber criminals, offering reduced sentences if they work for the government[1] "The cellmate said that people incarcerated for cybercrimes could get out before trial, in exchange for working for the government. Another inmate had already taken a deal, he said.

“It was an offer to cooperate,” Mr. Artimovich said.

“Why else would you work for the government?” he added. “The salaries are tiny. But if you do something illegal, and go to prison for eight or nine years, the F.S.B. can help you,” he said, using a Russian abbreviation for the Federal Security Service."
