Gainz for Dayz: Conventional vs Sumo Deadlift

What’s the best way to pick stuff up and put it back down?

Can Plants Talk to Each Other?

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.

Robots Could Soon Replace Human Stunt-Doubles

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.

Why your Muscles Hurt after a Workout

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.

Archerfish: Nature’s Master Marksmen

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.

Superhero Technology for Super Kids

Researchers have begun using exoskeletons (similar to Iron Man’s suit) to aid children with cerebral palsy in danger of losing their ability to walk.

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.
