Pseudopterosins are a family of naturally occurring chemicals with the power to reduce inflammation, skin irritation, and pain. In other words, they make a great additive in skin cream. If you want skin that less red, pseudopterosins can help. Want a lotion that soothes your face after a particularly vigorous round of exfoliation? Call on pseudopterosins.
Pseudopterosins come from a coral called Pseudopterogorgia elisabethae. That's it in the photo above. For years, researchers and pharmaceutical companies thought they were sustainably harvesting P. elisabethae because, instead of simply gathering any of the coral they could find, they merely pruned it — leaving plenty of the creature to grow back.
But, it turns out that this is a really good example of a frustrating problem — what seems sustainable is not always actually sustainable. Doing the right thing, environmentally speaking, isn't as intuitive as we'd like it to be. (Also, pruning an animal isn't like pruning a plant.) At Deep Sea News, Dr. M explains:
After prunings in 2002 and 2005 and before the annual spawning, Christopher Page and Howard Lasker examined 24 pruned corals and 20 unpruned corals. What the researchers found is that although colonies appeared healthy pruned corals produced less eggs. ... Why would pruned corals produce less eggs and sperm? When organisms are injured more energy is diverted away from reproduction and toward repair. Interestingly, this pruning may actually also creating artificial selection. If workers are targeting larger and fuller corals to prune, then smaller less thick corals will be reproducing more and eventually become more dominant.
This is why science is important. Because, frequently, "common sense" isn't really all that sensical.

Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else.

These toy planes are outfitted with ultra-bright LEDs, so you can fly all night without losing them in the trees.Whether you are a regular-sized child, or an overgrown adult one, these light-up flyers offer […]
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
