On December 16, 2017 at about 5:00 PM CST, the asteroid 3200 Phaethon passed within 64 million miles of Earth. That’s about 27 times the distance to our Moon. While this may sound like a long distance (indeed, it would take on the order of one million hours to drive that distance in a car!), this particular approach will be our closest encounter with the asteroid for another 75 years.

The Reason Sugar Tastes So Darn Good

Sugar is everywhere. Kids crave it, pastry chefs live by it, and dieters avoid it like the plague. It comes naturally in our fruits, it’s added to our drinks, and it’s found in some form in virtually every packaged item at the grocery store.

How a Pile of Uranium Changed the World

On December 3rd, 1942,  under the stands at the University of Chicago’s Stagg Field, scientists produced a breakthrough that would change the course of history.

LSD and the Elephant

Humans are wonderful research subjects.  They can think pretty well, and they can speak, too. Our ability to speak is probably our most prized asset in research, as it is the only way scientists can find out directly how their research subjects are feeling.  For all the good that humans provide in research, however, researchers can only do so much with their brethren. It would be unreasonably risky or unethical to perform certain experiments on their fellow humans.  This is where animals come in. Continue reading “LSD and the Elephant”

Training your Dog with Science

Dogs and their human family members have always shared a special bond. It’s no mystery to a dog owner where the phrase “man’s best friend” came from. While it’s tough to know exactly what your pet is thinking, it is possible to train them and communicate with them to foster a loving relationship. Lynn Meador is an expert dog trainer who works for Constant Companion Dog Training. Lynn’s goal is to work with dogs and their human family members to teach the two species how to communicate with each other and cohabitate in a supportive, loving manner.
