Via CNBC:

Unlike many hipster trends, there is at least one that science may have successfully demystified. Men are growing beards to assert dominance over other men and appeal to women, a report suggests.

Those are the findings of a new study commissioned by The University of Western Australia, according to a report in the UK publication The Telegraph. Published in the journal of Evolution and Human Behaviour, researchers studied 154 different species of primates, and found many males developed "badges" that boosted their sex appeal and made them more attractive to the females of its species.

Dr. Cyril Gueter told The Telegraph that the distinguishing characteristics among apes and monkeys correlated to beards in humans. The recent boom in male facial hair, Gueter says, is related to intra-societal competition among males.

guy uses chlorin e6 to get nightvision

Science for the Masses used chlorophyll analog known as Chlorin e6 (or Ce6) to give healthy eyesight temporary night vision. This chemical is found in some deep sea fish and used to treat night-blindness. 

The group hypothesized the chemical could be dispersed into the eye and give a form of night vision.

Did it work? Yes. It started with shapes, hung about 10 meters away. "I'm talking like the size of my hand," Licina says. Before long, they were able to do longer distances, recognizing symbols and identifying moving subjects against different backgrounds.

"The other test, we had people go stand in the woods," he says. "At 50 meters, we could figure out where they were, even if they were standing up against a tree." Each time, Licina had a 100% success rate. The control group, without being dosed with Ce6, only got them right a third of the time.
