The most sensitive weight scale ever can weigh individual protons

A new subatomic weight scale can measure masses as tiny as one yoctogram. Less than the mass of a proton, a yoctogram is equivalent to a billionth of a billionth of a millionth of a gram. » 4/01/12 4:00pm 4/01/12 4:00pm

Meet the periodic table's newest official elements

Elements 114 and 116 are now the heaviest elements that we know for a fact exist. They can only exist for less than a second, but they get us ever closer to the fabled island of stability. » 6/05/11 10:00am 6/05/11 10:00am

Balloons over Antarctica aim to solve space radiation mystery

Earth is surrounded by two huge regions of charged particles like protons and electrons, and these areas are known as the Van Allen radiation belts. These belts can mysteriously change their intensity, posing a threat to astronauts and sensitive electronics. » 3/20/11 2:15pm 3/20/11 2:15pm

The Ultimate Field Guide to Subatomic Particles

Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the different elementary particles. » 9/16/10 10:44am 9/16/10 10:44am

Undeterred by Time-Traveling Saboteurs, the LHC Begins Colliding

Take that, bread-dropping bird. Despite numerous delays and the suggestion that the Large Hadron Collider is being sabotaged from the future, the LHC is up and running. And, for the very first time, it has collided two proton beams. » 11/23/09 1:39pm 11/23/09 1:39pm

The Russian Cold War Rocket That Still Does Heavy Lifting

Click to view » 8/19/08 8:00am 8/19/08 8:00amThis Russian Proton rocket, looking like something out of a 60s sci-fi novel, launched yesterday from Baikonur Cosmodrome carrying one of the largest satellites ever built. Arguably the best heavy boost rocket in the world, the Proton is a Cold War relic that's still a workhorse (despite some recent…
