The future of hearing might be in your bones

How many times have you walked up to someone and were unable to get their attention because they had headphones on? This is an increasingly important issue as we become more connected to our devices and less connected to the world around us. Recently, several companies, including Aftershokz and Pyle, have tried to solve this issue by creating bone conducting headphones.

Secret Behind Kangaroos’ Tail

Red kangaroos can reach speed of more than 35 miles an hour, they can also cover an area 25 feet long and get up to 6 feet high in one jump using their tail like a spring to give them more power. When kangaroos want to move slowly, they do kind of lean on their tail, to support their body. When kangaroos are grazing they move their hind pairs of feet together which makes their movement awkward but the power behind them in their tail is keeping them balanced. There was always a question of why Kangaroos are placing their tail on the ground when they are walking slowly.

How the Mantis Shrimp Packs its Punch

The mantis shrimp, a six inch long crustacean residing in the warm waters of the Pacific and Indian oceans, may look harmless with its rainbow shell, but it is able punch its prey with the same acceleration as a 0.22 caliber bullet, providing around 1500 newtons of force with each blow. The mantis shrimp can shatter the glass of aquariums, catch and kill their prey with minimal effort, and punches so fast that cavitation bubbles form behind their hammer-like clubs. Cavitation bubbles are pockets of low pressure air that form when a liquid is moved faster than it can react, and collapse with tremendous heat and force—enough to crack the shells of other crustaceans or even a glass bottle.

Back Against the (John) Wall

What would you do if you went to the doctor expecting to get back to work, only to be told you might not ever be able to go back to work again?

According to ESPN, on February 4, John Wall visited his doctor regarding an infection in his heel after a previous operation. The doctor checked the infection, but upon further analysis, realized that Wall had suffered a partial Achilles tear. Unlike former teammate Boogie Cousins, he did not suffer the tear on the court, but at home. It was reported that while at home he fell and experienced extra discomfort in his heel. His doctor reported that he will undergo surgery and will likely rehab for the next 11 to 15 months.

Women in Endurance Athletics: The Further, the Faster

In the majority of athletic events, men have long outperformed women. This is due to a combination of factors including physiological differences, societal norms, and legislation. But in the last few decades, there has been a noticeable swing in the realm of endurance athletics. Now more than ever, women are closing the gap with respect to their male counterparts in ultra-long distance races, including running, biking and swimming. In some cases, women are even outperforming men at the elite level, winning a number of top-tier events. So what are the reasons for this changing of the guard, and why is it happening now?

Female Athletes Compete Against Higher Risk of ACL Injuries Than Males

Female athletes face a greater rate of anterior cruciate ligament (ACL) rupture than males. According to Dr. Karen Sutton and Dr. James Bullock from the Department of Orthopaedics and Rehabilitation at Yale University, female athletes are 2 to 8 times more likely to tear their ACL than male athletes. The majority of these injuries (more than two-thirds) are from non-contact situations. A variety of anatomical, biomechanical, and hormonal factors attempt to explain this difference.

Striking Out the Myths behind the Curveball

Anybody who has played baseball growing up was probably told “Don’t start throwing a curveball until you are ‘X’ years old.” That “X” in there for the age was normally around fifteen or sixteen years old depending on who you asked. When an eager, young ball player responded with “Why,” it was normally answered by “Because you will hurt your elbow and shoulder.” No sixth or seventh grade kid is really going to question that statement beyond asking another adult, and subsequently getting the same answer. Likewise, no youth baseball coach has really put in the effort to research whether or not learning to throw a curveball is detrimental health of young athletes.

Are Muscle Loads During Irish Dance Unsafe?

Do you think your ankle can bear loads more than 14 times your body weight? Can you look graceful while doing it?

This question is one of great importance for many athletes participating in high-impact sports. Dancers of all kinds have strived, for years now, to perfect the balance of athleticism and grace that their competitive markets demand. Achieving this balance is no simple feat, and many dancers fall victim to injuries during their countless repetitions of high impact leaps and landings, and Irish dancers are no exception. Researchers have recognized the need for biomechanical analysis of muscles and joints of Irish dancers, and created a model to do just that.

Do Wrist Guards Prevent Snowboarding Injuries?

Snowboarding is a breathtaking sport yet carries with it an inherent risk of injury. Wrist protectors provide potential protection against snowboarding wrist injuries. However, some studies have argued that wrist protection transfers the injury to other parts of the forearm.
