Physicists at the Large Hadron Collider have narrowed the range of energies at which they might find the Higgs boson, a particle predicted to give all others their mass. Science historian Amir Aczel discusses whether the particle might not exist, and how math sometimes leads physicists astray.
David Hu, mechanical engineer at Georgia Tech, wanted to understand the basic physics of how water striders glide. By filming them stride on food coloring and building his own robotic strider, he found out that the secret to the stride is in the paddle.
A relatively rare East Coast earthquake centered in Virginia shook people from Canada to Georgia. Carnegie Institute of Washington geophysicist Diana Roman explains the geology of the region, and the factors that allowed the earthquake's seismic waves to travel far and wide.
