It’s now safe to drop the ‘like’ from Higgs-like particle. http://www.flickr.com/photos/lightmash

Definitely, maybe: evidence grows for positive ID of Higgs boson

Physicists say they are now almost certain that the curious “Higgs-like particle” revealed last year at CERN is a Higgs boson. Data presented this week at the Rencontres de Moriond meeting in Italy – billed…
Annihilation of the universe is guaranteed to burst your bubble. Lu Lacerda

Could the Higgs mass determine the end of the universe?

Some say the world will end in fire, Some say in ice. Some say with a Higgs that light, One bubble might suffice. You may have heard in the recent media that the world was going to end. Uh, again. Worse…
We thought we knew the radius of the proton to within 0.8%. Perhaps not. Ludie Cochrane/Flickr

Updating the textbook: is the radius of a proton wrong?

Striving for agreement between theory and experiment and pushing the boundaries of precision are important parts of the scientific process. With each step in this process we move closer to enlightenment…
There’s an ongoing push to open the world of academic knowledge to the wider population … for free. Jackman Chiu

Open‑access journals: a perspective from within

There’s an ongoing debate in the world of academic publishing about whether the public should be allowed open access to research publications we all pay for in the first place. “If we are paying for this…

Large Hadron Collider hits the bottomium

A heavy variant of a particle first observed 25 years ago has been found in the debris of close-to-the-speed-of-light proton collisions in the Large Hadron Collider at Geneva. The particle Chi-b(3P) is…

Explainer: Einstein’s Theory of General Relativity

It’s the year 2100. You wake up alone in a small, windowless room. The only other thing in the room is a small ball. Maybe the room is located in your city, but maybe it’s inside that new spaceship everyone’s…
Another week, another rush to proclaim Einstein was wrong. Martial Trezzini/AFP

Neutrinos and the speed of light? Not so fast …

The bartender says, “We don’t serve your kind in here” A faster-than-light neutrino walks into a bar … The media is champing at the bit to proclaim a discovery of faster-than-light travel by a subatomic…
Theoretical physics strives towards a (beautiful) description of everything. Jinx!

Explainer: Standard Model of Particle Physics

The “traditional” beauty of theoretical physics is its equations. If we want to describe something, or the way something behaves, we can write down a relation between some properties we think that thing…
Is the “Z-prime” lurking within a “jungle” of particles at the LHC? Argonne National Laboratory

Explainer: the Z’ (hypothetical) particle

There’s nothing like an unexpected result to get physicists excited. So in 2008, when some strange behaviour was detected from a rarely-produced particle known as the “top quark”, there was much interest…
