The Physics Behind Why Cats Always Land On Their Feet (Video)

Almost everyone knows that cats have an extraordinary ability to land on their feet, even if they start out upside down. But how are they actually able to do this? Destin, founder of the popular youtube channel SmarterEveryDay, recently broke down the science behind how cats are seemingly able to always land on their feet. He posed the following question: How does a cat go from feet up to feet down in a falling reference frame without violating the conservation of angular momentum?

Forget Everything You Thought You Knew About “Horsepower”

Every time the newest model of truck or car comes out, the car manufacturers loves to tell you how much “horsepower” the vehicle has, conjuring up visions of muscular stallions galloping through the countryside. But I put the term “horsepower” in quotes because these visions are misleading. See, in our modern world, horsepower is simply a scientific unit that we accept as a standard. But to understand what it actually means, you have to understand where it actually comes from. The

This Amazing Ant Behavior Is Leaving Even Ant Experts Dumbfounded (Video)

Recently, a video surfaced of ants doing something quite amazing: forming multiple daisy chains to pull a massive centipede (presumably back towards their colony). Check out the amazing video below: According to Terry McGlynn, an Entomologist at Cal State University at Dominguez Hills, the video shows a species of Leptogenys ant somewhere in southeast Asia. What really shocked McGlynn about the video was that even ant experts had never witnessed this particular behavior before. Don’t get me wrong, ants have a long history

A 3-D Printed Robot Flying A Prototype for a Quadcopter Hoverbike (Video)

Back in May, I wrote an article about a futuristic new hoverbike called the Aero-X set to go on sale in 2017. Now it seems that the Aero-X may have some serious competition. A company called Malloy Aeronautics recently completely a successful Kickstarter campaign for a similar hoverbike that uses four helicopter bladed instead of two, adding additional control, stability and maneuverability to the craft. Though they haven’t yet built a full-size model, Malloy Aeronautics has built a 1/3 scale model that they’re

Just How Big Was the Biggest Bird Ever?

25-28 million years ago, a massive seabird known as Pelagornis sandersi dominated the skies. With wingspans reaching up to 24 feet in length, P. sandersi’s wingspan was more than twice as large as the largest living bird capable of flight, the Royal Albatross (which can have a wingspan of up to 11.5 feet). P. sandersi‘s wingspan was also… As big as many World War I fighter jets: Longer than three Yao Mings lined up head to toe: And longer than most adult anacondas: The bird was so

Chinese Boy Receives First 3-D Printed Vertebra Implant (Video)

Doctors at Beijing’s Peking University have made a truly monumental step in the field of orthopedic surgery: implanting the first ever 3-D printed vertebra into a 12-year old boy. After he suffered a neck injury while playing soccer, it was discovered that the boy had a malignant tumor on his spinal chord. Following an examination of the tumor, the boy’s doctors decided that their only choice was to remove his entire second vertebra. But rather than replacing it with a traditional orthopedic implant, the

Pictures That Show You Just How Extreme California’s Current Drought Is

If you weren’t aware, California is going through a very serious drought. 2013 saw the lowest rainfall numbers in California’s recorded history, and 2014 has been by far the hottest year on record for the state, according to the NOAA. The Palmer Drought Severity Index (PDSI) is a standardized metric which compares long-term droughts by looking at rainfall, temperature and soil moisture levels. The scale goes from +6 (very wet), to -6 (very dry). Anything below a -4 is considered

Did You Know… Muhammad Wrote A Letter Guaranteeing the Protection of Christians?

Muhammad, the prophet of Islam, lived from 570-632 AD. Muslims believe that he is the final prophet of the monotheistic Abrahamic tradition, which includes Adam, Noah, Abraham, Moses, and Jesus. So although it may come as a shock to many, it’s really not that surprising that Muhammad frequently visited the Christian monks of Saint Catherine’s Monastery on Mt. Sinai in the Sinai peninsula of Egypt. For those who aren’t aware, Mt. Sinai is the mountain that Moses climbed to retrieve the 10 Commandments in the Exodus chapter of the

How Ultraviolet Light Reveals All the Secrets Buried Just Below Your Skin (Video)

Ultraviolet or UV radiation is the radiation released by the sun. While the sun’s energy is obvious extremely important for our survival, the UV rays it emits can damage our skin over time. Examining your skin through an ultraviolet lens can reveal things you never knew were there (a lot of people have freckles they can’t see). It can also reveal changes and/or damage to the skin that is still invisible under normal light. Check it out in this awesome video posted

NASA’s Opportunity Rover Just Set the Off-World Driving Distance Record

NASA’s Opportunity rover landed on the surface of Mars in January of 2004. As of Sunday (July 26), the Opportunity rover had driven a total distance of 25 miles (40 kilometers). Opportunity took the top spot in total off-world distance traveled by surpassing Russia’s Lunokhod 2 lunar rover, which traveled a total distance of 39 kilometers across the surface of the moon between January and May of 1973. The Russian rover helped to bring about a golden age of space exploration in the
