More and more products are advertised for what they don't have instead of what they have. Everything is this-free and that-free. It troubles me that the word "free", which is supposed to mean something like wildness, is now used for puritanism. "Woo-hoo, the wind is blowing through my hair because of my dietary restrictions!" And what's with all these food allergies anyway? Whether or not they're psychosomatic, something new is causing them.
Also on the subject of food, I knew it! Why salad is so overrated.
This probably won't amount to anything, but it's cool: Physicists Show Molecules Made of Light May Be Possible.
More science: a great long article about the discovery of Homo naledi, a new human-like species remarkable for its small head, long legs, and abundant skeletons. The best part of the story is they had to recruit very skinny people with scientific credentials to get into the cave where the bones were discovered.
Finally, this is one of the best articles ever posted to the subreddit: Why boring cities make for stressed citizens. There's stuff about how we're biologically adapted for complex environments, how rats in stimulating environments are much smarter, and a bit at the end about how boredom might be good for us. I just got the idea that boredom is like drugs: it's good in moderation, and with the right set and setting.
