Pentaquarks and Tetraquarks

"LHCb discovers three new exotic particles"

The international LHCb collaboration at the Large Hadron Collider (LHC) has observed three never-before-seen particles: a new kind of “pentaquark” and the first-ever pair of “tetraquarks”, which includes a new type of tetraquark. The findings, presented today at a CERN seminar, add three new exotic members to the growing list of new hadrons found at the LHC. They will help physicists better understand how quarks bind together into these composite particles.

Quickly Disable Face ID On iPhone

"How to Temporarily Disable Face ID or Touch ID, and Require a Passcode to Unlock Your iPhone or iPad":

Just press and hold the buttons on both sides. Remember that. Try it now. Don’t just memorize it, internalize it, so that you’ll be able to do it without much thought while under duress, like if you’re confronted by a police officer. Remember to do this every time you’re separated from your phone, like when going through the magnetometer at any security checkpoint, especially airports. As soon as you see a metal detector ahead of you, you should think, “Hard-lock my iPhone”.

Smell And Friendship

Fascinating story on how people are more inclined to form friendships with others with similar body odor.

The methodology seems pretty sound. I'm intrigued that this could be yet another arena in which our ancient evolutionary/animal heritage can have a powerful subliminal effect on our "civilized" human life experience.
