Every animal has its rep. Rats are dirty; monkeys are cheeky; bats are blind. As anyone who's known an incurious cat can verify, though, these stereotypes are often false.
Here, modern scientific research takes a closer look at the truth about our animal friends.
Most spider webs work through chance: The spider erects an invisible trap and waits until some unlucky insect hits it. But a common Australian spider called the St. Andrew's Cross—known for its striking, cross-barred web—is sneakier.
Scientists have known for years that map sense stems from the magnetite in birds’ beaks, which measures the strength of the Earth’s magnetic field so they recognize home when they get there. But how do they know which direction home is?
the Blu-ray format stores and plays movies in high definition—easy for new flicks shot digitally in HD, but what about classics like Metropolis (due out on Blu-ray next year) that were shot on film? The trick is to make a small digital file without losing too much information in the process, which could yield a poor-quality image. Here's how it works.
The most powerful and complex science experiment in the history of the universe is finally—after 14 years and $10 billion—about to begin. There’s no telling what it may find, and that’s entirely the point
The proton is a persistent thing. The first one crystallized out of the universe's chaotic froth just 0.00001 of a second after the big bang, when existence was squeezed into a space about the size of the solar system. The rest quickly followed. Protons for the most part have survived unchanged through the intervening 13.8 billion years—joining with electrons to make hydrogen gas, fusing in stars to form the heavier elements, but all the while remaining protons. And they will continue to remain protons for billions of years to come.
