In June 2017, a group of congressmen were practicing for the annual Congressional Baseball Game when gunshots erupted. Quickly after the shooting began, House Majority Whip Steve Scalise was shot. Fellow Congressman Brad Wenstrup immediately worked to stop the bleeding from Scalise’s wound by using a tourniquet, a method of cutting off the blood supply to an injury.
Which dog breed is the strongest and healthiest of them all? Is it the Border Collie, with its elegant coat and affectionate personality? Or is it the English Bulldog with its burly frame and gentle disposition?
If you have school age kids in your life, you’ve probably noticed a lot has changed since you were their age. Smart screens and computer science courses are making chalkboards and writing in cursive obsolete. Another thing that’s missing: the classic PB & J. In fact, some schools have banned peanuts entirely due to allergies.
Blood transfusions are an essential component of modern-day medicine, saving lives in a variety of situations, ranging from genetic diseases like sickle cell anemia to road accidents. But, the history of blood transfusion is a rocky one. For instance, did you know that a German physician founded the world’s first blood transfusion institute in 1926 because he believed blood transfusions led to immortality?
Imagine you’re standing on the rocky, rust-pink surface of Mars. You’ve just finished a hard day’s work helping to build the first human base on another planet, so you decide to take a break and watch the sunset. As you gaze west across the Martian desert, a small, wan sun sinks through the hazy, orange-brown sky. The light wanes, and the temperature drops from a balmy daytime high of -15° F to an evening chill of -120° F (good thing you’re wearing your spacesuit). The weak wind that has been kicking up dust devils all day drops away, leaving you in a silence deeper than any quiet on Earth.
On a muggy day in June of 2018, after two and a half weeks at sea, the Research Vessel Endeavor’s crew, the science team, and I pulled into our last study site off the coast of Virginia. The weather was warm and overcast; the sea was calm. Dr. Miksis-Olds had just given the word to “pop the lander,” which meant to release the equipment anchored on the ocean floor. All us scanned the immediate vicinity, looking for the orange floats attached to the underwater microphones and other equipment. The equipment’s 20-minute journey to the surface was a waiting game we had performed successfully six other times: finding and retrieving the equipment, downloading the data it collected, and plunging the equipment back to the ocean floor to continue collecting data.
Machine learning impacts our everyday lives, whether we realize it or not. It determines what we see while scrolling through Facebook, what we see when we visit a company’s website, and how we interact with brands on the internet. You see ads based on your personal research, the key words used in your searches, and your individual preferences.
As I stood, gazing intently down near my feet, I felt the water flow past my knees. Even with my waders on, I could feel its cool relief in the summer sun. As I looked into the water, I caught a glimpse of a dark, circular shape under the muddy stream bed. I reached down to grab it, and as I pulled, I realized that it was not going to budge. What I thought was a lone bike tire was actually still attached to an entire bike, buried under the muck. I called my teammate, undergraduate researcher Sam Fredrickson, over and we traced the pattern of the metal crossbars and found a place to grip. With our combined effort, we pulled the frame free from under the layers of mud that had accumulated over it.
It’s Monday morning and your about to head out to catch your bus for work. You’re in a bit of a rush because, when you were getting dressed, you couldn’t find a two matching socks and you had to dig through the clean laundry still sitting in your dryer to find a matching pair. As you approach the door, you reflexively pat your pockets, checking for everything you need to bring with you. Keys? Check. Wallet? Check. Cell phone? Your phone is not there.

Ah, a day
at the beach. You find the perfect spot near the water’s edge, spread out your
towel, slather on some sunscreen, and settle in with a cool drink. You spot a sparkling white boat bobbing in
the distance, full of relaxed passengers tanning in the sun.
While this scene is full of idyllic summer imagery, is it also full of lurking danger? I’m not talking about sharks, but rather something much smaller: both the sunscreen you put on and the paint on the boat contain nanoparticles that provide important benefits but can harm both you and the environment around you.
Medical technology is rapidly advancing, with new technologies emerging faster than we can appreciate. Technologies such as liquid biopsies, 3D fluorescence imaging, and heart-in-a-box are just a sampling of the very cool advances we’ve seen in medicine in the past decade. Liquid biopsies can detect cancer in a patient’s blood, giving clinicians a reliable, non-invasive, and informative clinical tool to use to monitor cancer growth over time. Three dimensional imaging makes it easier to see what’s going on in your tissues. And heart-in-a-box allows donor hearts to live longer before transplanting them, giving time for hearts to travel far distances to patients in need. But, a tool that’s not so new yet is still particularly fascinating in its potential medical applications is the 3D printer.
Last spring, my wife and I took a trip to Bali for our honeymoon. While the trip was an absolutely incredible, once-in-a-lifetime adventure, the journey to our destination, as I described previously, was not a walk in the park. After 24 hours in transit through 13 time zones, where daytime accelerated and nighttime shrouded the plane in darkness for the majority of the trip, paired with my inability to sleep on planes, I was starting to regret ever getting a passport in the first place.Continue reading “A Tale of Two Speeds: How Planes Stay in the Air”
Fire is one of the most destructive forces that can wreak havoc on our communities. Forest fires and house fires threaten tenants, destroy sentimental belongings, and ruin everything in their wake. Although we typically view large fires as unruly and harmful beasts, there is one case in which fire actually rejuvenates the environment: prairie burning. Continue reading “The Science of Prairie Burning”
You’re in the midst of a headache, temples throbbing, and you rush to the drug store for medication only to have your headache intensify because you can’t decide whether you should get Tylenol or its generic form. Does that sound familiar? Ever dreaded having to pick up an expensive prescription and then been shocked to receive a generic version of it at a lower or no co-pay? (What a nice surprise!) Or, are you wondering why sometimes there is no generic alternative of your medicine available? Read on and hopefully, by the end of this article, you have all these questions answered.
Today, you can find hydrogenated butter with canola oil right next to transfat-free margarine. Partially-hydrogenated soybean oil a few aisles down from Omega-3 fatty acids. Your friends tell you that you can eat fat as long as you avoid sugar, while doctors tell you to avoid some fats because they’ll clog your arteries and cause heart disease. Yes, the world of fats is as complex as it is diverse. Continue reading “Say Goodbye to Trans Fats”
All of us have gone through the torment of high school—the growing pains and the mood swings and the cliques. It turns out that during development the cells of your body also go through something similar to high school. Once a new cell is created in the developing embryo, the cell undergoes a process called cellular differentiation, where it responds to varying cues to choose what kind of cell it’s going to be, or rather how it should respond to the incessant “what do you want to be when you grow up” question. The process of cellular differentiation in embryonic development is very similar to school—the cell enters the process naïve and innocent about the world, and leaves with an idea of who and what it wants to be.
