Does Sprinkles McFluffington have Resting Cat Face?

Why is your cat so judgmental?  Sure, you’ve been lounging on the couch stuffing your face and binging on Netflix for like seven hours. But still.  A animal who uses their tongue to shower doesn’t get to judge us, right? Nevertheless, our cats seem to direct a thick layer of skepticism and condescension toward us, even though we prepare their meals, clean their litter boxes, and buy them toys filled with catnip.

Liquid Rocks and Where to Find Them

Summer in Illinois can feel unbearably hot, but how hot is that exactly?  At 80ºF, Illinoisans can be found enjoying the sunshine and the reprieve from our winters.  At 100ºF, Chicagoans complain incessantly as cautionary heat warnings show up on billboards.  But what about, 200ºF?  Or 1000ºF?  These are the real extreme temperatures, and they are so hot that they literally melt rocks.  Believe it or not, parts of our very own planet heat up to these temperatures.  Continue reading “Liquid Rocks and Where to Find Them”

A Spoonful of Insulin Makes the Blood Sugar Go Down

Imagine drinking ten glasses of sugar water. What would you do after? Wash out your mouth? Eat something salty? You’d probably eat or drink whatever it takes to get rid of the extremely sweet taste. In the same way, when your body encounters high blood sugar, it tries to lower your glucose back to normal levels. Insulin, meaning island in Latin, is a hormone that is made in your pancreas.  Its primary role is to reduce your blood sugar. Defective insulin secretion, which is the hallmark of diabetes, can have adverse consequences in the body, such as unintended weight loss, increased thirst, increased urination, vision problems, and skin problems.

Our planet is home to a diverse array of habitats. These can range from cozy, nutrient-rich, temperature-controlled havens to deadly, gruesome battlegrounds where only the fittest survive. Each habitat, no matter how extreme, serves as home to millions of microbes. For instance, the microbes in our bodies are only happy at a balmy 98.6 °F. They live a cozy life, feasting on food scraps and dead cells in and on our bodies. However, not all microbes live in such luxury.

The Mystery of the DeYoung Diamond

A mystery red gemstone is in front of you on a table.  Is it a ruby?  Is it a garnet?  Is it a red diamond? 

The DeYoung Red Diamond, held in the Smithsonian’s National Gem Collection in Washington D.C., presents a perplexing case.  Observers originally thought the deep red 5.03-carat gem was a garnet. The large stone was set in a pin and purchased by a Boston jeweler at a flea market.  The jeweler, S. Sydney DeYoung, noticed that stone held up better over time than a garnet should. After some testing, he realized that his stone was actually a rare red diamond. He extracted it from the pin and willed it to the Smithsonian, where it is now on display.
