We already eat bugs
In fact, over 2 billion people eat bugs on purpose, though not typically in western culture. There are even cookbooks dedicated to gourmet insect cooking (here is one, if you are curious). But, most folks in the US eat bugs in our “normal” food unwittingly. Cochineal bugs, a kind of insect related to cicadas and aphids, are commonly used to make a red food dye called “carnelian.” If you have a strong stomach, take a look at the United States Food and Drug Administration’s The Food Defect Levels Handbook and you can see just how many bug bits are allowed in foods commonly produced and consumed in the United States.Continue reading…
The Poisoner’s Handbook: Murder and the Birth of Forensic Medicine in Jazz Age New York – Deborah Blum. A fascinating history of thescience of forensic toxicology in the United States, this book is equal parts crime drama and history of science. Ever wonder about what makes “denatured” alcohol? Would you have guessed it has to do with Prohibition? How did we figure out all that CSI stuff that modern forensic scientists use to determine how someone died? It’s all in here, and it’s super cool.Continue reading…

Dylan Dawson is a master’s student from a prestigious school majoring in industrial engineering. Besides academic responsibilities, he’s also involved in several extracurricular activities. His recent project is organizing a TEDx event on campus. Dylan Dawson is dealing with too many obligations right now, so he goes to his doctor and asks for a prescription of Vyvanse, a stimulant in the amphetamine class prescribed to treat mostly attention deficit hyperactivity disorder (ADHD). Dylan receives a temporary prescription for Vyvanse, so he can stay focused and motivated while juggling with classes, course work, working out, and organizing the TEDx event.
Dylan isn’t diagnosed with any pathological disease that would require him to take Vyvanse. The purpose of him taking this prescription drug is to ace all his exams, stick to his workout routine, and organize a successful TEDx event.
There is even a term describing Dylan’s situation: cosmetic psychopharmacology, coined by Peter Kramer, a psychiatrist and faculty member at Brown Medical School. Kramer defines cosmetic pharmacology as “using medications to induce desirable and socially rewarding personality traits in healthy individuals.” In case of Dylan Dawson, he used Vyvanse to enhance his cognitive performance to power through a challenging time even though he was perfectly healthy.Continue reading…
Deep in the Gombe National Park in Tanzania two famous primatologists, Richard Wrangham from Harvard University and Toshisada Nishida from Kyoto University, noticed an unusual dietary pattern among the local chimpanzees. The animals would dine on leaves of a plant from the daisy family called Aspilia. Instead of chewing on the leaves, the chimpanzees would put the leaves under their tongues for a stretch of time and then swallow the entire leaves. The chimps would frown while holding the leaves under their tongues for a good reason – Aspilia is known for its bitter taste. This means that the chimps were not eating these leaves because they tasted good but for another unknown reason that intrigued the scientists.
Fascinated by this observation, Drs. Wragham and Nishida sent samples of the Aspilia plant to a chemist, Eloy Rodriquez at the University of California in Irvine. After a thorough biochemical analysis, Dr. Rodriquez identified an abundant phytochemical in those leaves called Thiarubrine A, which acts as a potent antibacterial and antiparasitic agent. The chimpanzees consumed just enough of Thiarubrine A to kill up to 80% of parasites in their intestines.Continue reading…
Am I doing the right thing?
Many argue an artificial tree is better for the environment as you’re not cutting down a living tree; however, artificial trees need to be manufactured (usually using plastics and metal) which comes with a completely different host of environmental issues. To make a positive impact on the environment, you’ll need to use the same tree for at least 8 years, and maybe as long as 20 years in order to offset the environmental impact of building and transporting an artificial tree.
In some places (cities, or areas with no local tree farms), an artificial tree makes good sense, despite your grandmother’s disapproval of not having a “real” tree.
The best place to get a tree is at a tree farm. If you don’t have one anywhere near your house, it may be time to make an 8-20 year commitment to an artificial tree. If you are lucky enough to live with a tree farm near by, environmentally speaking, a real tree is the way to go. We all know that trees are good for the environment: eating up carbon dioxide and producing oxygen all the while providing a habitat for all sorts of cute critters. By supporting a sustainably managed tree farm, you can minimize your impact on the environment and still get a great natural tree.
