We have entered an era of renewed excitement regarding human space travel. The international community has lofty goals for the future of human spaceflight: returning to the Moon, sending crewed missions to Mars and other planets, and even colonizing space to save the human race when Earth is no longer habitable. These goals are beyond exciting, but before we can safely accomplish any of them, we must understand the biological consequences of space travel. For instance, it is well documented that space travel causes muscle atrophy, or deterioration. What causes this atrophy, and can how it be prevented?

Runner’s High (with guest speaker Emily Nist)
A discussion about the biomechanics behind running at altitude, including the effects of altitude on the body, how to combat it, and how to utilize it to enhance running performance.
Ski Racing: Where Champions are Made on the Course and in the Lab
If you have ever watched the winter Olympics, you have probably watched in awe as the alpine ski racers flew down the course. Years of training to perfect technique and build strength are essential for any athlete trying to compete with the best, but in a sport where hundredths of a second can separate first and second place, racers are always looking for ways to shave time. Understanding the forces that slow them down and their relationship to body positioning gives these athletes a competitive advantage.

The need for speed places fighter pilots in electrifying yet dangerous situations. When things go wrong during flight, pilots must consider ejecting, a terrifying choice. Ejection is a last resort due to the large compressive forces and the high wind speeds that can cause many different serious injuries, including spinal injuries. Approximately 20-30% of people who survive ejection endure spinal fractures. Understanding the dangers of flight that service members face increases awareness of the military lifestyle within the civilian population and is critical in finding solutions to lessen the severity of injury.

Have you ever wondered how a woodpecker is capable of banging its head against a tree so furiously without seriously injuring itself? The impact of a woodpecker’s beak with a tree can exceed speeds of up to 6 meters per second and occur over 12,000 times a day.These kinds of numbers are what allow woodpeckers to smash through trees to get to those tasty bugs that live inside.
