...warming. And this study offers an inkling of what it could cost us - if we don't act. "No matter how you slice it, these are big numbers," says Goodstein. "The Arctic air conditioner is breaking down in a big way. Half-measures won't work. If we can get carbon emissions down, we can retain more of this function...
...those that carry the weak force - came to have different masses as the universe cooled (in the moment after the Big Bang, of course, nothing had mass, existing instead in a sort of naked, ethereal beauty). Extrapolating from Higgs' theory, scientists were able to explain how all particles get their mass - which would explain, in turn, how everything in the universe, from scientists at CERN to the grand Jura Mountains that surround them, comes to have weight. (See "Did a Time-Traveling Bird Sabotage the Collider...
...works like this: Across the post-Big Bang universe, collections of Higgs bosons make up a pervasive Higgs field - which is theoretically where particles get mass. Moving particles through a Higgs field is like pulling a weightless pearl necklace through a jar of honey, except imagine that the honey is everywhere and the interaction is continuous. Some particles, such as photons, which are weightless particles of light, are able to cut through the sticky Higgs field without picking up mass. Other particles get bogged down, accumulating mass and becoming very heavy. Which is to say that even though the universe...
...Bang. The powerful LHC runs at up to 7 trillion electron volts (TeV) and sends particles through temperatures colder than deep space at velocities approaching the speed of light. (The second most powerful particle accelerator, at Fermilab in Illinois, runs at 1 TeV.) The added juice allows scientists to get closer to the high energy that existed after the Big Bang. And high energies are needed, because the Higgs is thought to be quite heavy. (In Einstein's famous equation E=MC2, C represents the speed of light, which is constant; so in order to find high-mass particles...
...question is, does this data really show that the ubiquity of cheap junk food will turn us all into junkies? Not really. A closer look at certain key elements of this study and of prior research helps clarify who - mouse or man - is most likely to get hooked and who isn't, and why addiction involves a lot more than mere exposure to a substance...
