Some bridges seem like they defy physics, with massive pieces suspended midair. It turns out the same concept that makes this possible also works on a smaller scale with Lego projects at home. Tension (the pulling forces on materials) and compression (the pressure on materials), give many st...
How far will Pluto go to get away from his Dwarf Planet friends? There isn't an American Girl doll for everybody. Just like the creators of Robot Chicken have done in the past, The Wild Thornberrys have to get extremely wild to stay on the air. ...

Seabirds are being devastated by predators, fishing, and climate change. Saving them begins with knowing more about them.
The divers’ pressurized atmospheric air was saturated with helium, which, being the smallest atom, passes through the microscopic gaps of even the most rugged diving watch. Once their ‘tour of duty” was over and they returned to ambient pressure conditions, the dial crystals of their Rolex ...
