Ask An Astrophysicist
The universe is being pushed apart at a faster and faster rate. And the culprit? Dark energy. Astrophysicist Adam Riess shared the 2011 Nobel Prize in Physics for that discovery, and now's your chance to ask him about it--or anything else you've been wondering about the cosmos.» E-Mail This » Add to Del.icio.us

Particles collide at Secret Garden Party
Guerilla Science staged a safari featuring quarks, electrons and bosons to help demystify particle physicsIn a soggy field in Cambridgeshire, an unsuspecting crowd was summoned from the tent where they were sheltering from the incessant rain to observe an exotic species of wildlife."Over there you can see the green quark – that's an up quark," explained the silver-clad tour guide to the onlookers as they watched the twirling figure in a green boiler suit. Dancing nearby were two more, in blue and red. "Quarks have three genders: red, green and blue. They're only really happy when the three are together in a loving bond."...

Turbulences at a standstill
Energy flowing from large-scale to small-scale places may be prevented from flowing freely in specific conditions. For one theoretical physicists, devising models of chaos and turbulence is his bread and butter. He has found an exception in a model of turbulence, indicating that there are energy flows from large to small scale in confined space.

Why maths should be compulsory for all A-level students
Studying maths until the end of sixth form would benefit both scientists and non-scientists, says Alice Udale-SmithWhen a House of Lords report suggested earlier this week that maths A-level should be compulsory for all sixth-formers, students were aghast.While some thanked the heavens they had escaped the proposals, others labeled the report ridiculous, pointing out that had they been forced to take a maths A-level, they may not have made it to university.Those who voted on Guardian Students' Facebook poll were also overwhelmingly opposed to the idea.It's not hard to see why.

Beyond the Higgs: Supersymmetry
As more evidence comes out showing that the Large Hadron Collider has located the Higgs boson (or some general Higgs-like particle), the next few years will focus largely on sifting through this evidence and refining the Standard Model of Particle Physics. They will conduct measurements from millions of particle collisions in the effort to more precisely define the physical properties of these Higgs-like particles (and the related Higgs field, which is the real object of interest)....Read Full Post

Quantum Levitation on TED
One of the most visually impressive recent discoveries in physics is the phenomenon of quantum levitation, in which a superconductor becomes suspended within a magnetic field. Quantum locking goes even a step beyond this. This isn't the same as just magnetic repulsion, though, because the superconductor itself doesn't have any electrical charge. Instead, it repulses the magnetic field around it, but if the superconductor is thin enough, then some of the field pops through the material due to the quantum Meissner effect. The result is that the magnetic field actually "locks" the superconductor in place relative to the sourc...

Brian Greene on the Higgs Field: Mass Molasses of the Universe
The Higgs boson is getting a lot of press since the July 4 CERN announcement that it may have been detected by the Large Hadron Collider, but the boson is only part of the story. See, the real work isn't done by the boson itself, but by the Higgs field, which theoretical physicist Peter Higgs proposed in 1964 as a means of explaining how the Standard Model of quantum physics could explain the mass shown by fundamental particles. The Higgs boson is just a physical manifestation of that field, created when you shove enough energy into it. (In quantum physics, fields and particles are viewed as different ways of representing ...

In a landmark study of atrial fibrillation, researchers from UCLA, UC San Diego and Indiana University report having found for the first time that these irregular heart rhythms are caused by small electrical sources within the heart, in the form of electrical spinning tops ("rotors") or focal beats. Importantly, they found a way of detecting these key electrical sources and of shutting them down in minutes using a precisely targeted therapy with long-lasting results.

This week's announcement of the discovery of the Higgs boson – the so-called God particle – was hailed as one of the great breakthroughs of the 21st century, explaining some of the fundamental physics of the universe. Yet in many ways the achievement has only highlighted how much we still do not know. The coming years will see humankind embark on new missions that will seek to advance our understanding: both into the limitless depths of space and the subatomic world within. Here are four questions that still vex science.
