Why should we care about the movement of octopus arms? Octopuses have evolved some of the most sophisticated soft-bodied mechanics in nature, capable of moving in ways that rigid-limbed creatures simply can’t. Their unique flexibility and control over movement offer valuable insights for fields like medical robotics, where delicate and adaptive handling is crucial. This research also helps us understand decentralized control, a model where each part of the body can act somewhat independently, a concept that may transform future technology in fields like disaster recovery robotics and innovative medical devices. By studying how octopuses control their arms, we learn from nature’s solutions to complex challenges.

Lymphatic Vessels: Your Body’s Fluid Highway
Have you ever heard about the lymphatic system that runs through your body? This system consists of organs, tissues and vessels that are important because it helps your immune cells move, helps your body absorb nutrients, and helps keep all the fluids balanced within your body. It is important to understand the way this system works, because when this system is damaged or not working properly it can lead to severe swelling of limbs (lymphedema), buildup of fats within your blood vessels which can eventually heart attacks (atherosclerosis), and even can contribute to cancer (To learn more).

Everyone has slipped or tripped at some point in their lives. Whether it is walking on an icy road to get to your car or tripping over the Lego set your kid refused to put away, everyday obstacles can cause us to lose our balance. Often this results in a brief moment of panic followed by the uneasy relief of regaining your footing, but for those who aren’t lucky enough to avoid falling, the results can be devastating. This is especially prevalent in populations more susceptible to falling. Falling in the workplace accounts for 16.8% of all non-fatal injuries leading to days taken off work. It is thought that this is due to the high volume of slipping or tripping obstacles encountered in some occupations. Additionally, 36 million falls resulting in 32,000 deaths were reported for the 65+ year old population of the US. Elderly individuals may lack the strength and reflexes necessary to recover their balance quickly. This is especially worrisome because the elderly are also the most at risk for the major health complications that can be caused by fall related injuries.

When cracking your knuckles, one tends to hear a “pop” noise that is loud, sharp, and irritating to most. This noise can be addicting in the sense that it makes others want to crack their knuckles. The main questions that I focused my research on were “Does cracking your knuckles or joints cause potential health issues for your future?” and “ Why does cracking a joint such as your knuckles make a “pop” noise?”

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.

Do you ever wonder what differentiates a casual skier from an Olympic level skier? The distinction lies in the immense forces these Olympic skiers’ output as they naturally transition from incredibly high speeds to sharp turns on the icy slopes. The four famous alpine skiing events held at the Winter Olympics are the slalom, giant slalom, downhill, and super-G events. In these events the human body is pushed to its limit with skiers experiencing forces of up to 2000N during turns through closely spaced poles and gates. Which is the equivalent of a 440-pound weight laying on top of you. These forces are integral in achieving faster times, better technique, and winning Olympic gold. How can these forces and techniques be optimized for the best possible ski run?

Dionea Muscipula, also known as the Venus Fly Trap, is universally considered an interesting and eye-catching plant. Most people are fascinated by its ability to snap its lobes closed around prey, allowing it to then chemically dissolve the trapped animal and subsequently absorb nutrients from its body. What most people fail to realize is the incredible amount of biomechanics required for this plant to survive. Not only is this information useful and interesting to know, but it is crucial for scientists to better understand how plants can respond to physical stimuli.

Vertical jumping is an essential aspect of many sports. In volleyball and basketball, for example, jumping higher than your opponent gives you a significant competitive advantage. Volleyball players need to be able to block and spike, while basketball players need to be able to rebound well and finish tough shots over opponents. Most athletes know the basics of jumping, but few know what specific body mechanisms contribute to jump height. This article will discuss four key elements to vertical jump height:
- Squat depth
- Non-extension movements
- Arm swing
- Toe flexor strength
Understanding the mechanics behind each of these elements can help guide athletes in training regimens to better increase jump height.

The majority of people know what a fall is and, in fact, many people have unfortunately experienced one or a few. But what would be a good definition for what a fall is? Simply put, a fall is something that happens when you lose your balance and cannot recover. Falls have the potential to ruin anyone’s day. For some, however, the risk is far more severe than that as falls are one of the leading factors in injury and death among the elderly population. This will continue to be a problem as the number of elderly people in the United States is expected to increase dramatically over the next fifty years.
