Capuchin monkeys were first trained to exchange stickers, habituated to being head-touched, and exposed to a horizontal mirror. Then, their mirror self-recognition was tested by surreptitiously placing a sticker on their forehead before requesting them to exchange stickers.

In line with previous studies, this result suggests that capuchin monkeys lack the ability to recognize themselves in mirrors.

An L.A. Startup Aims To Turn The Oceans Into A CO2 Sponge And ‘Green’ Hydrogen Machine “ocean water contains 150 times more carbon dioxide than the air, which means if you want to remove carbon dioxide from the atmosphere one of the most effective ways to do it is by removing it from the oceans,” […] His hope, and that of backers including the Grantham Foundation, Chan Zuckerberg Initiative, Singapore’s Temasek Foundation and U.S. Energy Department, which have contributed $30 million so far, is that Equatic will be removing millions of tons of CO2 in the years to come—and do so for less than $100 per ton. Sant also expects the company to generate hydrogen for $1 per kilogram that it can sell or use to help power Equatic’s operations.

Written by just three men, Aeschylus, Euripides, and Sophocles, these works represent a tiny fraction of those that would have been performed at the grand theater festivals of ancient Athens, beginning in the fifth century BCE. Of the more than 300 known tragedies from that era, the vast majority exist only as fragments.

Denis Hopper was able to sustain his lifestyle and a measure of celebrity by acting in numerous low budget and European films throughout the 1970s as the archetypal “tormented maniac.” […] Hopper’s cocaine intake had reached three grams a day by this time, complemented by 30 beers, and some marijuana and Cuba libres. […] After staging a “suicide attempt” (really more of a daredevil act) in a coffin using 17 sticks of dynamite during an “art happening” at the Rice University Media Center (filmed by professor and documentary filmmaker Brian Huberman), and later disappearing into the Mexican desert during a particularly extravagant bender, Hopper entered a drug rehabilitation program in 1983.
