The Earth is a gigantic ball of semi-molten rock, with a heart of iron as hot as the surface of the Sun. Titanic amounts of heat left over from its birth and the radioactive decay of trillions of tons of radioactive elements find no escape but up. Currents of rock spanning thousands of kilometers carry […]
When radium was first discovered, its luminous green color inspired people to add it into beauty products and jewelry. It wasn’t until much later that we realized that radium’s harmful effects outweighed its visual benefits. Unfortunately, radium isn’t the only pigment that historically seemed harmless or useful but turned out to be deadly. J. V. […]

Florida might seem like a bad place to launch rockets from, especially because of the terrible weather, but there’s actually two very good reasons why NASA is doing it from there. First, as our planet rotates on its axis, it generates kinetic energy, and as you get closer to the equator, this kinetic energy increases. […]
Carbon nano-onions aren’t the latest craze in molecular gastronomy, but they might represent the future of medicine and electronics… [SciShow]
If you drop a penny from the Empire State Building, will it kill you? Science educator Derek Muller from Veritasium, with the help of Adam Savage, decided to put the old urban myth to the test by dropping a bucket of pennies on Muller from a helicopter. Needless to say, he survived the experiment. Watch […]
