Hope for a New Particle Fizzles at the LHC
A curious signal of a potentially revolutionary new particle detected last year turned out to be a fluke
Just How Resilient Is Spacetime?
A hundred years on, and the implications of Einstein's general relativity still surprise and delight
100 Years of Great Physics: Watch Live Monday and Tuesday [Video]
General relativity and Noether’s theorem take center stage in two live Web broadcasts this week
Neil deGrasse Tyson at 85% the Speed of Light
This video made me laugh harder than anything I’ve seen in a long time. Okay, except for some Louis CK videos. But for a non-comedian (allegedly)… this is hard to beat.

Darwin's Living Legacy--Evolutionary Theory 150 Years Later
A Victorian amateur undertook a lifetime pursuit of slow, meticulous observation and thought about the natural world, producing a theory 150 years ago that still drives the contemporary scientific agenda...
Using Causality to Solve the Puzzle of Quantum Spacetime
A new approach to the decades-old problem of quantum gravity goes back to basics and shows how the building blocks of space and time pull themselves together
