A new study examines the blurry distinction between “hard” and “soft” drugs.
The “hardness” of drugs is a concept that makes intuitive sense, but is difficult to put into precise terms. “Hard” drugs are those which are viewed as more addictive, more potent and more toxic than the comparatively benign “soft” variety. The concept has a normative aspect: “hard” drugs are bad, and you should avoid them, even if you use soft dru ...read more
Your dog may act like a good listener—but does she really notice when you’re feeling down? Or does she just know how to deploy a wet nose and a tail-wag to earn treats? A new study says negative emotions are contagious for dogs. They’ll pick up a companion’s bad feelings just by sound, whether that companion is human or canine.
“Emotional contagion” is the most basic form of empathy, write Annika Huber of the University of Vienna’s Cleve ...read more

On rare occasions throughout history, the darkness of night fails to materialize. Even with the moon darkened, the sky fills with a diffuse glow that seems to filter out of the very air itself. Such “bright nights” have been recorded back to the days of Pliny the Elder around 132 B.C., although explanations for the phenomenon have been lacking.
Using a special interferometer and data from the 1990s, two Can ...read more
“Waste not, want not.”
The origin of this proverb traces back centuries, but time has hardly tarnished its relevance. It’s a warning every generation would do well to heed: Mismanaging precious commodities today will lead to an impoverished future. It’s so simple. It’s so true. It’s so often ignored.
Case-in-point: global industrial fishing operations. Over the past decade, fishing fleets simply threw away more than 10 percent—enough to fill 4,500 Olymp ...read more

Excerpt from the Apollo 11 transcript. NASA.
One hundred and 31 hours, 42 minutes, and 30 seconds into the mission, the crew of Apollo 11 was reunited and preparing for the trans earth injection burn that would send them out of the Moon’s orbit and on a path back home. Command Module Mike Collins was still in his pressure suit — mission rules said the astronauts much be suited when redocking the Command and Lunar modules — and was getting ready to take it off for the TEI burn ...read more

Humans are sort of nature’s wimps.
Relatively speaking, our physical prowess just doesn’t match up to the rest of the animal kingdom. Our lack of brawn is a result of our our big, energy-hungry brains, an adaption that seems to have worked out pretty well, all things considered. Still, without the aid of tools and traps, creatures who call the wilderness home present a clear threat. Even when compared to our closest cousins, chimpanzee ...read more
