The Science Behind Tattooing

Once the social symbol of sailors and jail-hardened individuals, tattoos have surged in popularity among the global youth, with around 40% of adults between the ages of 18 and 29 sporting some ink. Tattoo artists spend years training and a lifetime honing their craft, often specializing in one of many forms of skin-based expression ranging anywhere from portraits to calligraphy to watercolor. Whether you’re a fan of the “I-Love-Mom” classics or elaborate Monet-esque mosaics, the practice of tattooing seems almost magical in nature – and like many other tattoo-lovers out there, you’ve probably found yourself wondering: how in the world do tattoos even work?

I Ate a Bug, and I Liked It

I Ate a Bug, and I Liked It

What would it take for you to eat bugs? I mean, besides the “worm” at the bottom of a tequila bottle. (Your motivation is apparent in that case). Would you do it if it were healthier for you than our typical western diet? Would you do it if it might help to save the world? I decided to explore those questions after watching a video featuring Nicole Kidman munching down a bunch of bugs and calling them delicious.

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…    

Editor’s Picks: The UYBFS Summer Reading list!

Hello gentle readers, and welcome to the first edition of the UYBFS book club! As much as we like writing about science, we enjoy reading about it, too, especially all the strange and interesting history behind many scientific discoveries that we now take for granted. There are a lot of great books out there, and here Editor David has collected a few of his favorites. Why not add some to your summer reading list? Dazzle your friends with trivia!

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…    

Stephen Hawking’s Final Paper was Published Today

Stephen Hawking’s Final Paper was Published Today

Stephen Hawking died in March, but his final peer-reviewed paper was published today in The Journal of High Energy Physics. As you might expect from a genius like Hawking, the data presented are… complicated. Basically, it says that if there are, in fact, alternate universes in existence (like Timecop!), they share at least some unifying laws of physics.

Consider the following scenario:

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.

What helped Dylan succeed?

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…    

Do monkeys have the cure for cancer?

Do monkeys have the cure for cancer?

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…

The Science of Keeping your Christmas Tree Fresh

The Science of Keeping your Christmas Tree Fresh

Every year millions of people world-wide cut down a perfectly good conifer and welcome it into their home for Christmas. There is a lot of information out there on issues from the ecological impact of using a live vs artificial tree to how to keep your tree looking “fresh” the longest. Here’s a quick  look at the science of Christmas trees!

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.
