Take a look at this fascinating video of a dragonfly up close, seemingly smiling, dabbing, and posing with human-like expressions in front of the camera.
Is it doing the Macarena, doing the YMCA, or dancing to Madonna’s song ‘Vogue?’
They dance while they’re young
Dragonflies have been around nearly 300 million years and can reach speeds up to 31mph when in flight. But once the dragonfly larvae propel off the water and into the air it only lives for about a month.
If any of the 5,000 species of dragonflies land on your head, the theory goes, count yourself lucky.
Iguanas in South Florida are falling out of trees due to freezing temperatures.
Weather in South Florida dropped into the 30s on Tuesday night, which immobilized the iguanas and turned their bodies dormant.
“Don’t be surprised if you see iguanas falling from the trees tonight,” the Miami National Weather Service office tweeted.
The good news is that the iguanas woke up when the heat turned back up on Wednesday morning, like this one. While Miami suffered its coldest temperatures in 9 years, it’s expected to be back to 80 on Friday.
What looks like it was taken out of a country western film, here are two Kangaroos fighting each other from the outback in Australia.
Kangaroos usually loaf around most of the time — if they’re not eating or jumping around — so to see them duking it out like humans in a good old boxing match is fascinating.
For all the jokes about humans fighting kangaroos, it seems unlikely that humans could defend against the extremely muscular hind legs of these marsupial kickboxers — their kicks are so lethal they can crush bones!
But in more serious terms, if you want to donate to help fight the rampant Australia fires — of which millions of wild animals have been a victim, including kangaroos — donate here.
“When you’re hit on the football field, parts of your brain may fizz like a just-opened can of soda.”
The brain released humans from the prison of biology. So why do we do anything that damages our ability to think? Because of sports like football that entertain.
However, a new technology designed to mimic a woodpecker’s shock-absorbing beak may prevent football players from brain injury.
“It likely clinched its jugular vein with its long omohyoid muscle, protecting against brain slosh by filling its brain with blood.”
Scientists first theorized that increasing blood to the brain would help safeguard the head against collisions. Existing data revealed that playing football at higher altitudes generated fewer concussions. However, scientist Joseph Fisher thought he could still protect players’ brains without suffocating their oxygen. He went back to study the physiology of the woodpecker’s distinctive “omohyoid solution” for battling head trauma.
“forget CO2, Fisher thought. All you needed was to press lightly on the neck. Fisher bought a pair of headphones at an electronics store, bent the metal band a little, and placed them around his neck with the pads against his jugular veins.”
Naturally, scientists tested the hypothesis on rats by putting a neckband on them and forcing collisions. The neck-protected rats saw an “83 percent reduction in brain damage compared to rats that didn’t.” Scientists got approval to test a neck collar on high school football players.
“The kids who had worn the collar, on the other hand, saw significantly fewer changes. Their brains hadn’t suffered the same way. The findings were also replicated in hockey players. What worked for woodpeckers seemed to work for humans. A little extra blood in the skull swaddled the brain enough to reduce damage.”
In other words, squeezing the jugular sends just enough blood to the head to prevent brain injury and in the long-run, dementia caused by CTE. Astonishing, right? It makes you think why the NFL does not have an R&D department. The worst-case scenario? Figure out how to play American football using bubbles.
