There are people who need far less sleep than average. Several mutations have been identified in certain genes that could explain this. But what these genes do is unclear. I am not so blessed and need my sleep time, but I can get away with less for a while, before the need for sleep returns and I must nap. Short naps seem to be restorative, but there is more to it, depending on my emotional state, etc.

A third kind of magnetism has been discovered - altermagnetism. There's actually three other types, though: diamagnetism paramagnetism and ferromagnetism. Anti-ferromagnetism and ferrimagnetism are just variants of ferromagnetism. But altermagnetism is different, and could have practical applications.

Wow! I love perpetual calendars as a kid and thought they were works of genius, until I found out how regular the calendar is. But this one really takes it to the extreme, and is designed with so much thought and planning. Seeing such genius and then looking at the world today, knowing that there are a lot of people who would destroy it in an instant, in the name of some stupid cause, is really depressing. We live in the world where we can't have nice things. Even the Chapel of Bankers and Merchants is a work of art. We have truly regressed.

How to hack an electronic road sign. I've seen this before. This is why people are able to hijack these things, and I'm surprised that they haven't improved security.

About 1 in 7 science papers are fake. And it's going to get worse. I read the paper mainly out of curiosity to see how the estimate was determined, and it's just a metasurvey. No one really knows, and this is really disturbing.

You can't trust AI-generated news headlines, even from big names, such as Apple. This is really sad.

Speaking of not being able to have nice things, this is an example of the Ronin's Second Law again. People wanted BlueSky to be like the old Twitter days, when left-wing viewpoints predominated. But open it up to the public, and you know there will be stuff you don't like. But they want to ban free speech, instead of just ignoring it, like adults. Welcome to the real world. Nothing stays nice once everyone gets access. Get used to it.

Could skin bacteria be turned into a vaccine? Staphylococcus epidermidis seems to be suitable for something like this.

Some people think that Apple will revive making WiFi routers again, like the Apple Extreme. This could be interesting. My old Airport Extremes are still working and doing fine. Great workmanship.
