A dozen quintets of UNLV students have been probing the valley’s neighborhoods the past few Thursdays, taking note of markets, liquor stores, clinics, pharmacies and access to public transportation.

John Mercer, a biomechanist in the department of kinesiology and nutrition sciences at UNLV, has dedicated the majority of his adult life to testing the limits of physical abilities.

The significance behind this study helped researchers understand the effects of shock absorption in terms of preventing running injury.

Master’s student Ka-Voka Jackson has combined her passion for biology and the environment with her Native American roots to help solve environmental issues from a unique perspective.

While 3D printed prosthetics are good at helping people complete simple tasks like holding a pen or opening a door, we’ve also seen some special 3D printed prostheses for use in activities like playing an instrument, running, or playing sports, like baseball. 7-year-old Hailey Dawson, who is missing the three middle fingers on her right hand, wants to show people that kids with handicaps like hers can still have great lives and enjoy normal activities. You may ask how exactly she plans to do this, and the answer is pretty interesting – by throwing out the ceremonial first pitch for every Major League Baseball (MLB) game.

A sound night’s sleep grows more elusive as people get older, but what some call insomnia may actually be an age-old survival mechanism.

Trouble sleeping is a common complaint among older folks, but what if their insomnia traces back to prehistoric times when Grandma and Grandpa were in charge of keeping the cave safe at night?

If your sleep is getting worse with age, evolution might be to blame. A study recently published in Proceedings of the Royal Society B found that humans' age-specific sleep patterns may have evolved to protect mixed-age groups from potential danger in the night. And in this scenario, the elderly members of these groups may have drawn the short straw—their restless sleep made them perfect for the night watch.

You may not look forward to sleeping less as you get older. But maybe it wouldn’t seem as bad if you knew it once played an important role in human survival.
