About 100 trillion neutrinos just passed through your body a second ago. Did you feel them? Neutrinos are one of the most abundant particles in the universe, but they’re also the most elusive. They can pass through just about anything, including your body, without being noticed. Now, imagine if we could harness this power. Imagine the possibilities if you could control a particle that can pass through anything undetected.
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.

Somehow, the first seizure I recall makes me giggle. I was getting changed after sports at school, age 6-ish, when I had a focal seizure, a seizure that starts on one side of the brain. The problem really was that I was still only half-dressed when I started walking down the corridor in only my underwear. It wasn’t until I was about to enter the classroom that I came out of the seizure. Can you imagine how different my life might have been if I had half-flashed my classmates?!

If you ever decide your smartphone camera isn’t cutting it and you want to buy a standalone DSLR camera, you’ll find that you have a lot more control over how your photographs come out. DSLRs come loaded with lots of features and settings that contribute to the overall look of your photographs, all of which are either controlled automatically by your phone or not available at all. Use these features the right way, and you can capture images your phone never could.Continue reading “How to Take Great Photos: The Three Pillars of Photography”
Chances are, you’ve had a few opportunities to be crippled by symptoms of anxiety in your life. Maybe it was a first day at a new job or a social occasion with no familiar faces. Perhaps it happened right before you needed to perform in front of an audience. These occasions can be few and far between for some or chronically debilitating for others. Any way you experience it, anxiety generally comes with the same set of symptoms—accelerated heart rate, increased blood pressure, an abrupt tightness in your stomach. What’s happening here is your body’s fight-or-flight response, the automatic physiological and psychological behaviors that prepare your body to react to a perceived danger.Continue reading “Viva Las Vagus”
Think back to your days in chemistry. What tools were most useful to you? Your goggles? A lab coat? Maybe it was the notebook where you scribbled furiously so as not to forget anything. However, there’s another tool you might have forgotten, that has proven itself extremely useful for generations of students and scientists: the periodic table of elements. Continue reading “The Father of the Periodic Table”
Oh, how I love riding my bicycle! It has gotten me all over Chicago, all along the lakefront from the far south side to the north suburbs, through the college neighborhoods and the ethnic neighborhoods, residential ones and industrial ones, and through downtown. My bicycle has enabled me to explore parts of the city I never pass through or only stop in for specific reasons, with direct exposure to the sights, sounds, and smells of each local community.Continue reading “The Bicycle: A Marvel of Physics and Engineering”
Have you ever wanted to build a suit that gives you superhuman capabilities? What would you do if you could store energy in the fabric of your clothes or had gloves with extra sticky fingertips that could help you climb buildings? What if you had special silverware that told you the ingredients in a suspicious looking meal, or nail polish that changed color based on the presence of an air contaminant? Continue reading “Be a Superhero with Biomimicry”
As the pairing of “measles” and “outbreak” screams across the headlines of countless news outlets, the majority of us experience an internal and instinctive shrinking back. But why? Is this learned response necessary, or is it simply the result of scare tactics and media hype? Continue reading “Is the Measles Really That Bad?”
As a high school student, I had a love of technical subjects, such as physics, math and computer programming. I also spent a great deal of time in art classes. I was blessed with a generous and dedicated art teacher (thank you, Leona Mackey).
Those interests overlapped for me in photography, which I dove into deeply. While shooting, I immersed myself in my senses. When composing, I leveraged intuition and critical thinking. And in the darkroom, I practiced my analytical thinking skills as I developed and printed my photographs.Continue reading “Navigating the Space between Art and Science”
Ironically, despite the horrors of war, armed conflict has a way of advancing medicine. Gruesome injuries sustained on the battlefield provide opportunities for surgeons to experiment and test new approaches for treatment. During World War II for example, blood poisoning, bronchitis, and other infectious diseases contracted by soldiers created a demand for broad spectrum antibiotics, which encouraged British scientists to find new ways to produce penicillin on a mass scale.
Hydrogen-powered cars are a promising technology. They are clean, could potentially be powered by renewable energy, and plus, they just sound like the future, right?
Hydrogen-powered cars, also known as fuel cell vehicles, are a type of electric vehicle: they use electricity to run a motor that turns the wheels. The car contains pressurized tanks of hydrogen and it passes the gas through a fuel cell to generate the electricity to run the motor. You can think of a fuel cell as a kind of electric generator, but instead of running on gasoline, it uses hydrogen as fuel.Continue reading “How Soon Will We All Have Hydrogen-Powered Cars?”
“CBD.” Perhaps you’ve seen these letters shining bright, in green neon, on a store window in a seedy part of the city, fronting a shop with glass vials and trinkets lining the shelves and creepy men behind the counter. Or, maybe you took a stroll downtown on a sunny day and walked into CVS or Walgreens, only to see these same letters on small boxes lining the shelves next to the vitamins. You might be wondering what’s going on – how could the same compound be proudly sold in shady hemp shops and mainstream convenience stores at the same time? What is this confounded chemical?Continue reading “The Truth about Cannabidiol (As Far as We Know)”
Imagine a computer that doesn’t use electrical devices to process information but instead uses individual atoms. These computers, called quantum computers, have the potential to solve all kinds of complex problems, from cancer to street traffic, which regular computers struggle to do. While these computers are still in development, and have been for a couple of decades, the first rudimentary versions have recently started to take form.Continue reading “A DIY Guide to Building a Quantum Computer”
What makes dogs so doggy? You might have noticed that your dog has traits, like floppy ears, a curly tail, speckles or patches, or a cute, short nose, that make it look pretty different from the wolf it’s descended from. For more than a century, scientists have wondered why so many domesticated animals, ranging from cows to pigs to mice, share traits like these that don’t exist in the wild animals they’re related to. Continue reading “The Moving Cells that Make Our Pups the Pups They Are Today”
Every day, a fine sprinkling of dust covers your city or farm, landing across the roof of your house or onto the hood of your car. Some of it may settle in your hair, or onto the vegetables you eat in your salad. If you take a closer look, you’ll notice it isn’t just any dust – it’s oddly metallic and finely grooved.
It’s estimated that companies and governments will spend over $124 billion dollars this year on security measures to protect your data. But with a disguise, the right piece of specialized equipment (which is basically a USB stick on steroids that I could purchase for $49.99 during a Christmas sale), and about 10 minutes, I, a 20-year old college student, can make all that security worthless.
If you reach into your back pocket or bag, a small device likely hides in the depths. Perhaps you’re holding it right now, using its screen to read these words. Of course, I’m referring to the cell phone which 92% of Americans now possess. This tiny device has utterly revolutionized our concept of communication and catapulted us into a new digital age in only a few decades—but also into an era of digital insecurity as millions per year are hacked through smartphone apps or other security compromises. As a result, industries and researchers have begun to explore the possibility of using fundamental laws of physics to create an impenetrable communication system.
