Element 114 on the brink of recognition
NewScientist    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The periodic table is set to get bigger, now that three labs have independently made atoms of element 114. There's still one big uncertainty though -- should it be classified as a metal or as a noble gas? In February, an element with 112 protons in its atomic nucleus was recognized and named copernicium by the International Union of Pure and Applied Chemistry (IUPAC). A similar honor should shortly be on the way for element 114. Read the associated Physical Review Letters papers here and here. More

Quantum dots for highly efficient solar cells
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The efficiency of solar cells could be increased to more than 60% from the current limit of just 30% according to new work by scientists in Minneapolis and Texas. The new work involves capturing the higher-energy sunlight that is normally lost as heat in conventional devices using semiconductor nanocrystals, or quantum dots. More

Hotspots leave magnetic scars on Mars
Nature News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
After the Mars Global Surveyor (MGS) settled into orbit around the red planet in 1997, a magnetometer on board began sending back measurements that have puzzled planetary scientists ever since. A section of the Martian crust appeared to consist of long 'stripes' of iron-bearing minerals permanently magnetized with alternating orientations. Clearly, an ancient dynamo imprinted its field in the rock during the planet's early history. But why the stripes? More



Nanoscale imaging technique meets 3-D moviemaking
Scientific American    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Three-dimensional movies are everywhere these days, and the novelty is poised to become a big-screen mainstay. Now the field of microscopy is getting into the act, too, but the end product is very different from 3-D movies such as Toy Story 3 or Avatar. More

LHC scientists simulate the sound of the 'God Particle'
Popular Science    Share    Share on FacebookTwitterShare on LinkedinE-mail
article
If a theoretical force-carrying, subatomic particle were to materialize in the universe and no one were around to hear it, would it make a sound? Existential aspects aside, physicists at the Large Hadron Collider believe that the elusive Higgs boson, should it prove to be real, will most definitely make a sound, and they plan to be around to hear it. In fact, that's one of the ways they plan to detect the so-called "God Particle," and they've simulated the sounds a Higgs boson might make so they can listen for its arrival. More

South African physicists working to protect data networks at the World Cup hope to provide something that no goalkeeper can promise: perfect defense. They're tapping the laws of physics to prevent hackers from monitoring videos, emails and phone calls relayed between Durban's Moses Mabhida Stadium and a nearby operations center for police, firefighters, and military personnel.
