Artificial turf fields were first introduced in the late 1960s and have grown tremendously in popularity since. Today, artificial turf fields can be found at all levels of sport, from youth league to professional, and across many different sporting disciplines. A major reason they are so popular is because they offer a consistent, low-maintenance, year-round green playing field in all weather conditions and climates. However, despite the benefits they provide, artificial turf fields are not without controversy. Even though artificial turf mimics grass in appearance, its properties are much different.

Muscle Loss Due to Aging
It is a well-known fact that as we get old, our bodies (sadly) deteriorate, leaving us unable to perform certain physical functions as easily as we could have when we were younger. In this article, the authors describe a study done to analyze muscle loss due to aging, primarily by examining two different age groups of humans. By conducting measurements on people over and under the age of 40 years, results show a clear difference in muscle mass and strength between the two.

Anyone who has worn high heels, or has even simply seen a person in high heels, knows that the foot is definitely not in its usual position in that kind of shoe – walking is more difficult and forget about even trying to run in high heels. Researchers from Manchester Metropolitan University and the University of Vienna wanted to investigate if frequent, long term use of high heels caused lasting changes in the calf, in addition to the normal discomfort experienced by high heel wearers.

Just because you can’t walk on water doesn’t mean you shouldn’t run under it!
Aqua-jogging. Hydro-running. Water-treadmills. Have you ever heard some combination of these terms and wondered what the hype is?

When something bad happens, do you tell your friends? Do you warn the people around you? Similar to human beings telling one another about risks and dangers, plants can communicate with one another about environmental stressors.

Imagine an aerial acrobat soaring fifty feet above your head and executing gravity-defying stunts during a live performance. After your initial amazement that a human could be performing acts such as these so fearlessly, you look a bit closer to realize that the performer is actually not human at all. Thanks to a groundbreaking technology recently developed by Disney Research, this could soon become a reality.

How often do we cut our overly ambitious workouts short because of exhaustion or muscle soreness? Probably more than we care to admit. But have you ever stopped to ask yourself why your muscles hurt, especially a day or two after your workout? The simple answer is, you’ve put so much strain on your muscles that you aren’t used to, so they tore, and now your body has to repair the tears and build up more muscle, so the same thing doesn’t happen in the future.

The name archerfish refers to seven species of freshwater fish that are all members of the Toxotes genus. These fish derive their name from their ability to hunt land-based creatures, ranging from insects to small lizards, using jets of water shot from their mouth with remarkable accuracy. They only grow to a maximum of a foot long, but they’ve been recorded in the wild propelling their water jets distances of up to two meters. A recent study in the Journal of Experimental Biology was conducted by Stephan Schuster to investigate the mechanics behind their unorthodox hunting technique.
