This looks like an interesting book. [Amazon Link]. Nat Geo has an interview with the author, David Waltner-Toews, that includes details such as, "in the slums of Nairobi, human poop powers hot showers and other services. In California, dog doo-doo keeps a dog park electrified."
The author offers this summary of his book: "as soon as you have life, you have essentially poop. As life developed, the waste for one animal became food for another animal. We depend on a web of recycling of nutrients, and poop is an important part of that. People get sqeaumish but they shouldn’t be. If you don’t think of it as poop, but instead think of it as recycling nutrients, this is a really interesting and sustainable way to produce food."
Jake Allgeier studies fish urine. I guess someone has to. He says that there's a lot more of it than you would think, and it's a lot more important for marine environments than people realize. From redandblack.com:
"A funny comparison is if you take the biggest ungulate herd — so that would be bison, antelope, deer and elk — in Yellow Stone National Park, per meter squared — so per unit area — the fish on one of the reefs that I look at...they actually pee more than three times more [than that herd]," he said. Fish urine even dwarfs fertilizer-heavy golf course runoff — per meter squared — in nutrient content.
Researchers Anna Lomanowska and Matthieu Guitton spent a year examining scantily-clad avatars in the game Second Life in order to determine just how much skin they show — and whether the female avatars show more skin, on average, than the male avatars. A tough job, but someone had to do it! They discovered that "virtual females disclose substantially more naked skin than virtual males." This adds to the growing body of evidence that pretty much everyone likes looking at naked women. (Advertisers have known this since forever.) Their full article can be read at PLOS ONE.
Researchers at the University of Southampton and Sun Yat-Sen University collaborated to explore whether feelings of nostalgia help protect people against the cold. They conducted various experiments (published in the Journal Emotion) such as 1) putting people in a cold room, asking them to recall a nostalgic event from their past, and then asking them to guess the temp; and 2) asking volunteers to recall a nostalgic event while their hand was dunked in ice-cold water.

The researchers concluded that overall recalling nostalgic events "evinced greater tolerance to noxious cold." So instead of turning up your heater this winter you could save some money by wistfully remembering the good old days instead.
Why would nostalgia keep you warm? The researchers suggest that "the nostalgia-warmth link derives from a universal mental association between interpersonal affiliation (which nostalgia fosters) and warmth, which is rooted in infant-caregiver interaction."
But, of course, more research is necessary. For instance, the researchers propose that future investigations will explore whether "nostalgia functions in a different capacity for individuals reared in warm (compared to colder) climates. Conceivably, in colder climates nostalgia could primarily serve to ameliorate thermoregulatory (cold) discomfort, whereas in warmer climates it could primarily serve to ameliorate thirst."
I'm always fascinated by scientists who are also bonkers about the supernatural. Even Isaac Newton dabbled in the occult, which was more understandable for his era.
But here's a twentieth-century fellow who led such a double life: Edgar Lucien Larkin.
I'm sure you will want to read all 366 pages of his masterwork to be found here.
