If you think your “organic” crops are free of synthetic chemicals, urine for a shock. 😉
In a randomized, single-blind pilot study, researchers found that anticonvulsive epilepsy drug carbamazepine, which is released in urine, can accumulate in crops irrigated with recycled water—treated sewage—and end up in the urine of produce-eaters not on the drugs. The study, published Tuesday in Environmental Science & Technology, is the first to validate the long-held suspicion that pharmaceuticals may get trapped in infinite pee-to-food-to-pee loops, exposing consumers to drug doses with unknown health effects.
It’s a red flag for me when the researchers add an unknown variable right in the middle of the study (they “ran out of vegetables grown with reclaimed water” and used grocery store vegetables instead, which they assumed would be a mix) rather than start the study over, especially when the study is only over the period of two weeks and a relatively small number of participants.
Lucky for the females, 25 million years have provided ample time to refine their skills as apothecaries. Arriving at the entrance of an aggressive male’s shelter, all a female lobster needs to do is spritz him with some of her pee, a little each day over several days, and he will be putty in her claws.
Most people know about the strange smell that asparagus gives off after it has been, ahem, processed by some humans. Yet other humans aren’t able to smell the odor at all. That makes asparagus an unusual marker for the intricacies of genetic variation.
Your urine may be of more use kept about your person. At least, that’s what a team of researchers from the University of the West of England think, because they’ve made a pair of socks that use the liquid to generate electricity.
The first I remember to suggest such technology was the stillsuit in Dune. Which brings up the point that this could be beneficial for travel in places such as space. Electricity doesn’t do much good in the desert 😉
…and wearable charging technology has been talked about for a while, with respect to supporting our cellphone/mobile and such.
Cyanide poisoning is not a nice way to go. Essentially it’s open-air suffocation. Cyanide ions in the body interact with an enzyme called cytochrome oxidase. This enzyme works with hemoglobin in the blood. It preferentially picks up cyanide when it should be picking up oxygen, meaning the body slowly dies for lack of “air.”
There’s a classic joke about how to get intoxicated at hospitals by claiming you drank methanol to get an IV with an ethanol solution. It’s not that methanol will kill you or make you blind… The problem is that the liver enzyme alcohol dehydrogenase turn methanol into formaldehyde (or methyl aldehyde). Ethanol binds to the same enzyme to inhibit the production of formaldehyde.
Picture yourself with your very own backyard pool. There you are, drifting on an inflatable raft, wearing a cute bikini, sipping a fruity drink, wiping the urine from your eyes…wait—what now? Sometimes ignorance is bliss when it comes the germs you’re being exposed to on the regular—otherwise how would you leave the house? But the Centers for Disease Control (CDC) would prefer you actually learned something about these issues.
It’s interesting to realized that for advanced as we think we are, it’s only been within the last 100 years that things really picked up. And even today, there’s stuff that we use but don’t fully understand why it works.
Unrelated, but the first couple of lines reminded of the classic:
