The new method uses equipment many laboratories already have and is New worlds orbiting strange stars are waiting to be discovered...and we're on the hunt. What could we accomplish with machines that draw power from the air around us? Getting humans to Mars safely means figuring out how to protect the body from the damage of cosmic rays. Using cutting-edge machine-learning technology, scientists are pushing the envelope of quantum computing. The sw*llow tanager gets its brilliant blue and turquoise hues by harnessing the wavelike properties of light. The interior of a neutron star plays host to strange phases of matter unlike anything seen here on Earth. Laser blasts and levitation team up to make testing water for heavy metals a cinch! When GPS isn't an option, scientists turned to physics to control and track swarms of underwater sensors. Sometimes, all it takes to unlock ancient secrets is to look at the problem in a new light. Get creative and learn the basics of magnetism at the same time with this fun blend of art & science! Watch the interplay of electricity and magnetism in action, with this see-thru version of a clas*ic physics demonstration! Learn how this mysterious force works with a trip to the playground! In this edition of the PhysicsCentral podcast, we hear from a few teams who are still in the running for the CubeQuest Challenge: a contest for homegrown teams to build their own small satellites - cubesats - and compete against each other by demonstrating technological feats. Five million dollars in prize money will be divided among teams who can get into orbit around the moon, maintain a
