The Secret in Your Veins: The History of Blood Transfusion

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?

Blue Sky at Night, Martian’s Delight: The Atmosphere of Mars

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.

The Art and Science of Sound in The Sea

 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 & How It Affects Our Daily Lives

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. 

What most people may not realize though is that machine learning impacts parts of your life you may not have even considered, such as your finances, your healthcare, and even the ways in which we communicate with one another.

A Day in the Life of a Garbage Scientist

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.

How Your Brain Finds your Phone When You Hear it Ringing 

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.

Na-No Thank You? Exploring the Dangers of Commercial Nanoparticles

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.

Artificial Organs? How We Can Get There with 3D Printing

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.

A Tale of Two Speeds: How Planes Stay in the Air

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.

Brand-Name Drugs vs. Generics: What’s the Difference?

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.

Say Goodbye to Trans Fats

Today, you can find hydrogenated butter with canola oil right next to trans fat-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”

A Cell’s Search for Identity

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.

Blood, Sweat, and… Saliva: How Our Bodily Fluids Can Save Us

Picture a fighter pilot commanding a plane as they engage in aerial combat.  When you think of the greatest threats to the pilot’s safety, you probably think of attacks from other aircraft or the risk of crashing the plane as they swiftly maneuver it between various obstacles.  But what about the potential for harm coming from inside the pilot’s own body?  For example, the stress the pilot is feeling might give him or her a heart attack.  Similarly, their severe dehydration could lead to heat stroke.  Both of these conditions would spell disaster for the pilot.  While often overshadowed by the inherent hazards of weapons and machinery, these ailments pose a very serious threat to the safety of military personnel.  But how can we know if someone is dehydrated or enduring dangerous levels of stress while they’re thousands of feet in the air?

On a Small Island in Indonesia: The Last Dragons on Earth

Halfway across the Earth, nestled deep within the Indonesian archipelago, lie two small, tropical islands unlike any others on the planet. From the United States, it takes at least three planes, a boat, and a couple of days to get there. By the time you dock at the main pier on one of these islands, you realize that you’ve stepped foot into an entirely different world. There is no technology – no cell service, no internet, no cars; not even paved roads. It’s just you, a guide, and the wilderness around you.

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.
