What’s more important for athletes: training or genetics?

Usain Bolt, Michael Jordan, and Wayne Gretzky are arguably some of the greatest athletes of all time. You watch them on the television breaking record, winning titles or making impossible shots, and you can’t help to wonder, how are they that good? Do they use some secret training method, maybe even a special diet? Possibly, they are genetically gifted?

Cause and Management of Stretch Marks

Stretch marks. How are they caused? Can they even be treated?

Stretch marks can happen to anyone, of any age, so these questions are important to many. In short, our skin is made up of both collagen and elastin, two elements that support and shape our skin through their natural elasticity. This elasticity, however, does have its limits. And when that breaking point is reached, the collagen and elastin rupture, leaving behind scars many know well – a stretch mark.

The Study of Snoring is Anything but Boring

Here we take a deeper look about that noise that plagues some of our family members, our roommates…or even ourselves!

The Ship of Pearl – Jet Propulsion in the Chambered Nautilus

In the aptly titled poem The Chambered Nautilus, Oliver Wendell Holmes Sr. praises the eponymous cephalopod for its elegant shape and vibrant colors. The ship of pearl, as Wendell calls it, might not be the swiftest vessel; but Thomas R. Neil and Graham N. Askew’s research indicates that the chambered nautilus might be among the most energy efficient ships in the seven seas.

Will Removing Headgear Make Boxing Safer?

Our brains are made of a very soft material but luckily our skulls provide the brain protection from the outside world. However, during violent movements the brain is free to move inside the skull and collide with the skull. This impact can cause injury to the brain, known as a concussion, that can lead to various symptoms depending on severity.

Biomechanics: a Key Factor in Rehabilitation of Neurological Diseases

In the rapidly evolving modern world, technological advancements are allowing for more effective research and treatment of diseases, disorders, and injuries sustained by humans. One of the foremost areas of current research in the biomechanics field is that of its role in treatment and rehabilitation of neurological disorders such as amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS). According to the United Nations, as many as 1 billion people in the world live with neurological disorders. This post will focus mainly on how biomechanics can aid in the treatment and rehabilitation of ALS and MS.

Exciting Advance in ACL Repair

Anterior Cruciate Ligament (ACL) injuries are among the most common in sports, with nearly 100,000 tears annually. Additionally, the rate of pediatric tears has been increasing at a rate of 2.3% each year for the past 20 years. The high incidence of this injury is in part due to the structure of the knee complex, where the ACL is located. The ACL helps connect the two longest bones in the body and is responsible for rotation and transferring body weight to the ankle. Specifically, the primary functions of the ACL are to prevent the tibia from sliding too far in front of the femur and to provide rotational stability to the joint. This rotational motion, combined with a lack of muscle support at the knee, is why so many athletes tear their ACL. A recent paper looked into how a team of doctors led by Dr. Martha Murray at Boston Children’s Hospital have come up with a promising new approach to repairing the injured ligament.

Scleroderma and Raynaud’s Phenomenon: Cold Weather’s Influence on Skin

Anyone who is familiar with winters that are mainly at temperatures in single digit range knows how crucial gloves are to surviving the tough, frigid weather. If one was to go outside without them, their hands become extremely pale (or sometimes almost blue) and, once back inside, take a bit of time to get back to normal. It’s a tough life, I know, but people with a scleroderma have an even harder time surviving the winter. What is scleroderma, you ask? Scleroderma is an autoimmune disease that causes skin and internal organs to thicken, and if that wasn’t tough enough, a good chunk of people with it also experience secondary Raynaud’s phenomenon, which is an exaggerated vasoconstriction of arterioles in response to cold weather and causes a drop in blood flow. The main, visible outcome from this disease is how the skin whitens and swells. Problems must ensue from the combination of thick skin and lack of blood flow to the extremities, right?

Fish in Flight: The Science Behind Great White Breach Attacks on Cape Fur Seals

If you’ve ever turned on Discovery channel during Shark Week, then you’ve probably seen the iconic footage of a 2.5-ton great white shark leaping out of the water to catch its next meal. If you’re weird like me and you’ve ever tried to mimic one of these epic breaches in a backyard pool, then you realize just how difficult it is to generate enough momentum to jump even partway out of the water and therefore have a real appreciation for what it takes to pull off this incredible feat.

The Unfair Advantage: Prosthetics and Their Role in the Olympics

In 2012, the “Blade Runner” Oscar Pistorius became the first double amputee to compete in the Olympics. Ever since this historic occasion, the issue of whether prosthetics should be allowed in athletics has been a topic of controversy in the media. Do prosthetics give amputees an advantage over able-bodied athletes? Are athletes with prosthetics capable of running faster and performing better than able-bodied athletes?
