Scientists at SLAC decided it was time to upgrade some of their kit, and the result is the laboratory’s most powerful laser system ever. The device will create temperatures up to millions of degrees and pressures approaching 2 trillion pounds per square inch. Read more…

One day we might be able to make home refrigerators without any chemicals or industrial coolants. The main hope for this comes from a special property of metal and a quirk of entropy. Read more…

StartsWithABang writes: Over 100 years ago, Rutherford’s gold foil experiment discovered the atomic nucleus. At higher energies, we can split that nucleus apart into protons and neutrons, and at still higher ones, into individual quarks and gluons. But these quarks and gluons can combine in amazing ways: not just into mesons and baryons, but into exotic states like tetraquarks, pentaquarks and even glueballs. As the LHC brings these states from theory to reality, here’s what we’re poised to learn, and probe, by pushing the limits of quantum chromodynamics. Read more of this story at Slashdot.

How Pentaquarks May Lead To the Discovery of New Fundamental Physics
After restarting to run at higher power than ever , the Large Hadron Collider has made its first proper discovery. Today, a team of scientists announced that they’ve found a new class of sub-atomic particles known as pentaquarks. Read more…

The LHC Has Discovered a New Sub-Atomic Particle Called a Pentaquark
Metals, which conduct electricity, and insulators, which don’t, are polar opposites. At least that’s what we’ve believed until now. But we have discovered that a well-known insulator can simultaneously act like a conductor in certain measurements . We don’t yet know the reason for this mysterious behaviour but it is likely due to new and exciting quantum effects. Read more…

Researchers at the University of Tokyo have dusted off some E Ink technology originally developed back in the 1970s to create a new kind of easily erasable whiteboard technology that can be written on using magnetic pens instead of dry-erase markers. Read more…

The lure of quantum entangled computing is strong, as it can provide a means of impenetrable encryption —but the hardware has always been too bulky to make it practical. Now, though, researchers have shrunk the technology down to less than the width of a human hair, small enough to squeeze onto a chip. Read more…

The technology available to image light as it moves through space continues to advance. Recently, we saw a new high-speed camera capture a small pulse reflected from a mirror ; now, it’s possible to image the entire flight path of a laser as it bounces around a laboratory. Read more…

Graphene has very many strengths , but there is one thing it isn’t and that is magnetic. Now, a team of researchers has found that the insertion of a little lead into the planar graphene structure can change that. Read more…
