Physicists at Fermilab discover new subatomic particle
Symmetry Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced the observation of a new particle, the neutral Xi-sub-b. This particle contains three quarks: a strange quark, an up quark and a bottom quark (s-u-b). While its existence was predicted by the Standard Model, the observation of the neutral Xi-sub-b is significant because it strengthens our understanding of how quarks form matter. More

Tevatron experiments close in on favored Higgs mass range
Fermilab    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The search for the Higgs boson is entering its most exciting, final stage as physicists at Fermilab are close to reaching the critical sensitivity necessary to look for the existence of a light Higgs particle. If the Higgs particle does exist, then the Tevatron experiments may soon begin to find an excess of Higgs-like decay events. If the Higgs particle does not exist, Fermilab's Tevatron experiments are on track to rule out the predicted Higgs mass range in 2012. More

New theory of cuprate superconductivity described
Brookhaven National Lab    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In work published in Science, physicists have described the interplay between microstates in nematicity and topological defects in cuprate superconductors. Cuprate superconductors have lots of states that can compete with superconductivity. Building on experimental observations, theorists constructed aGinzburg-Landau functional describing the coupling between the competing states and that correctly predicts their interplay at the atomic scale.

Research outlines math framework that could help convert 'junk' energy into useful power
Physorg.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In a paper in Physical Review E, theoretical physicist SurajitSen and colleagues describe how altering the shape of grain-to-grain contact areas between the particles dramatically changes how energy propagates through a granular system. Crafting such designer particles would enable scientists and engineers to control how energy travels through the system. The researchers assert that their framework could one day form the basis of technologies that turn road vibrations, airport runway noise and other "junk" energy into useful power. More

Astronomers find largest, oldest mass of water in universe
Space.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Astronomers have discovered the largest and oldest mass of water ever detected in the universe — a gigantic, 12-billion-year-old cloud harboring 140 trillion times more water than all of Earth's oceans combined. The cloud of water vapor surrounds a supermassive black hole called a quasar located 12 billion light-years from Earth. More

HartRAO celebrates its 50th anniversary in July
Tech Central    Share    Share on FacebookTwitterShare on LinkedinE-mail article
First built by NASA as one of three tracking stations for its space program, the Hartebeesthoek Radio Astronomy Observatory turns 50 this year. Today, HartRAO has active programs in geodesy and is a member of European VLBI Network. The facility is an important center for work towards the South African SKA pathfinder, MeerKAT. HartRAO is also leading an effort to convert communications dishes across Africa into an African VLBI Network. More

Quantum decoherence overcome
Vancouver Sun    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In a paper published in Nature, researchers at the University of British Columbia and the University of California Santa Barbara announced they have found a way to deal with decoherence — the tendency of atomic-scale particles to get quickly tangled up with the larger physical world we live in. Their work opens up a whole new area for researchers who are investigating the potential for development of quantum computers. More

The unplanned impact of mathematics
Plus Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
British mathematician Peter Rowlett introduces via an article in Nature, seven little-known tales illustrating that theoretical work may lead to practical applications. Rowlett argues that practical impacts can't be forced and it can take centuries to manifest. His discussion seems to be primarily motivated by the recent emphasis on the "impact" of research, both in Britain and in the U.S. More

Budget cuts bite for UK physical sciences
Nature News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The U.K.'s Engineering and Physical Sciences Research Council has begun to reveal the research fields for which it will cut funding as a result of budget restrictions — and why. EPSRC says that it will ramp up support for research on quantum information, and maintain current levels of funding for graphene and carbon nanotechnology. The U.K. has already announced deep cuts in astronomy and particle physics research. More
