The Science Behind Blushing from Embarrassment

Can you think of the last time you felt embarrassed in public? Maybe you tripped over a chair during a work meeting or fumbled your words during a presentation. Whatever the reason, did you feel the telltale signs of embarrassment? 

Understanding the Physiological Effects of Aging: Part Two

Aging is a complex process that affects every part of our body, from the surface of our skin to the intricate systems working underneath. In Part One of this series, we discussed the external and internal changes related to the musculoskeletal, cardiovascular and respiratory systems. However, many significant changes also occur within our immune, nervous and digestive systems: ones that can profoundly affect our quality of life as we grow older. In Part Two of the series, we’ll explore what these systems do, the changes that occur with age and how they can influence your health. 

Understanding the Physiological Effects of Aging: Part One

If you finally get around to sorting through those old boxes in your garage, you might stumble upon photos of you and your loved ones over the years. As you sift through them, you’ll likely notice physical changes: graying hair, fine lines, and maybe even a few extra pounds.  But what about the changes no photo can capture? While a picture might be worth a thousand words, it can’t tell the full story of how time affects the body on a deeper, physiological level. Let’s take a closer look at some of the body’s systems and the physiological effects of aging to better understand the full impact of getting older.   Exterior Changes As we age, changes to our outer appearance are often the most noticeable:  Skin At 30, you could probably bump your arm on the sharp edge of the countertop and walk away unscathed. Two decades later, the same accident might result in an unwanted scratch or bruise. This is due to a reduction in collagen production, which makes the skin less elastic and more prone to scrapes and bruises

Biotechnological Innovations in Tissue Engineering

Ever wish you could just 3D-print a new knee after a long morning run? Thanks to some major breakthroughs in biotechnology, that idea isn’t as farfetched as it once seemed.   Today, the global market for tissue engineering is worth about $20.1 billion, and it’s expected to double by 2033. That growth is fueled by the rising demand for regenerative therapies, advanced procedures and a growing interest in repairing the body in ways once thought impossible. 

What Is a Gap Year — and Is It Right for You?

You’ve seen it in movies: The main character, destined for college, shocks everyone by taking a year off to travel or pursue a passion before deciding their next move. But what about in the real world? How does a gap year play out for students who’ve just earned their undergraduate degrees and are contemplating medical school? 

Spotlight on Career Paths: CRNA

An oral surgeon is removing a wisdom tooth. The unconscious patient fidgets. Another trained professional boosts the anesthesia level. The patient stays calm, still and unconscious for the rest of the procedure.

Advancements in Biotechnology for Diabetes Management

Prior to the discovery and use of insulin as a treatment for diabetes in the 1920s, people living with the disease had few treatment options, and essentially no good ones: bloodletting, starvation diets and various potions deceptively marketed as cures.  Today, countless people have been able to bring their diabetes under control through a combination of exercise, dietary adjustments and insulin injections. However, though often effective, these approaches aren’t always practical.  As diabetes management has advanced, new technologies have emerged that address the need for more practical and convenient treatment options. Here we’ll look at some of the current biotechnology helping individuals with diabetes live healthier and less disrupted lives. Implantable Devices: The Future of Diabetes Care  Continuous Glucose Monitor (CGM)  A CGM assesses the wearer’s glucose every few minutes and tracks this information. These biotechnology devices evaluate the level of glucose in the fluid between cells, not the blood itself, but the numbers are generally comparable.   The device has a small sensor that can be inserted under the skin of the abdomen or arm and kept in place by an adhesive patch
