American Institute of Physics is conducting a global physics survey: Your responses are needed
American Institute of Physics    Share   Share on FacebookTwitterShare on LinkedinE-mail article
The American Institute of Physics is collecting responses to the global survey of physicists. The survey has been open for some time, but if you have not already participated, please do so at www.aipsurveys.org/global. Make sure your response is included in this unprecedented effort to collect data from physicists across the globe. The survey will be until Nov. 30. More



NSBP Member Warren Washington receives National Medal of Science
University Corporation for Atmospheric Research    Share    Share on FacebookTwitterShare on LinkedinE-mail article
President Obama has named long-time NSBP Member Warren Washington, a senior scientist at the National Center for Atmospheric Research (NCAR), as one of 10 eminent researchers to be awarded the National Medal of Science. Dr. Washington received his first physics degree from Oregon State University. He later earned his Ph.D. in meteorology at Penn State. He along with the other National Medal laureates will formally receive their awards at a White House ceremony Nov. 17. More

Large Hadron Collider achieves heavy ion collisions
Asymptotia    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The first heavy ion collisions were observed at 1 a.m. local time Nov. 7, in the Large Hadron Collider (LHC) near Geneva, Switzerland. By the following Monday morning the heavy ion beam was stably producing a steady stream of collisions such that the physics analysis could start in earnest. By the end of the week a sufficient number of events had been observed to reach the first conclusions.

Witnessing this historic event was Dr. Zinhle Buthelezi from South Africa's iThemba LABS who was on duty in the control room of the ALICE (A Large Ion Collider Experiment) detector at the time of the first collisions. Other members of the iThemba LABS team, Deon Steyn, Siegie Foertsch, and Zeblon Vilakazi as well as the team from the University of Cape Town led by Jean Cleymans have also been participating in the ALICE experiment.

ALICE, Quark-Gluon Plasmas and the origin of the universe
A Large Ion Collider Experiment    Share    Share on FacebookTwitterShare on LinkedinE-mail
article
The goal of ALICE is to observe the so-called Quark Gluon Plasma (QGP). This plasma is analogous to the more well-known electronic plasma that results when a gas is so hot that its electrons are liberated from their atomic nuclei. Like electrons are constituents of atoms, quarks and gluons are constituents of nucleons – protons and neutrons. They can likewise be "deconfined" from nucleons at high energy densities like those that existed at the very moment of the Big Bang, or can be reproduced in high energy accelerators like the Relativistic Heavy Ion Collider (RHIC) or the LHC. Thus the results gained from ALICE and RHIC give insights into the state of energy and matter in the first microseconds of the universe, before condensation into neutrons, protons and subsequently atoms.

Experimental Excitement
ALICE - A Cosmologist's Point of View

Theoretical physicists have studied QGPs using a variety of techniques. Perhaps the most successful method is due to Dr. Juan Maldacena, a plenary speaker at the 2005 Joint Annual Conference of the National Society of Black Physicists and the National Society of Hispanic Physicists. The so-called "AdS/CFT correspondence" relates string theory to gauge theories like quantum chromodynamics (QCD) which describes the interactions between quarks and gluons. Professor Jim Gates has commented, "So, the next time someone tells you that string theory is not testable, remind them of the AdS/CFT connection." Since then experimental, observational and theoretical evidence has expanded from particle theory to condense matter physics.




South African participation at CERN
African School of Physics    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In addition to the ALICE experiment, South African physicists are participants in the ATLAS experiment. Dr. Simon Connell, President-elect of the South African Institute of Physics leads the ATLAS Team at the University of Johannesburg. "ATLAS is designed to answer some of the most fundamental questions about the nature of the universe, like how and why particles have mass," he explains.

This past summer South Africa hosted the first biennial African school on fundamental subatomic physics and its applications. The school attracted 65 students with 23 different citizenships from 17 African countries. Learn more.

South African participation in particle physics brings many benefits to the country and continent, most notably in information and computing technology (ICT). SANReN, the grid computing network that allows physicists in South Africa to receive results from the LHC is used by many others in science and business, and this network will by design be extended to everyday consumers and learners.


Nuclear weapons transformed into medical physics applications in South Africa
Deccan Chronicle    Share    Share on FacebookTwitterShare on LinkedinE-mail article
South Africa has transformed apartheid-era nuclear weapons into a tool for detecting cancer and heart disease, with a new technology that could ease global worries about nuclear arms trafficking. After voluntarily dismantling its weapons program, democratic South Africa used the leftover nuclear fuel to produce medical isotopes used by doctors for imaging technology. More

The U.S. Civilian Research Development Foundation (CRDF) is a non-profit organization that promotes U.S. science diplomacy efforts around the world, under the banner "peace and prosperity through international science collaboration." It recently launched Global Innovation through Science and Technology, a two year program for strengthening science ties with Muslim majority countries that builds on proposals announced by U.S. President Barack Obama in Cairo, Egypt, in 2009.

Hidden in plain sight: Researchers find galaxy-scale bubbles extending from the Milky Way
Scientific American    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A group of astrophysicists has located two massive bubbles of plasma, each extending tens of thousands of light-years, emitting high-energy radiation above and below the plane of the galaxy. The researchers found the structures in publicly released data from NASA's Fermi Gamma-Ray Space Telescope, which was launched in 2008 to investigate sources of extremely energetic photons—namely, gamma rays, which have higher frequencies than x-rays.

Why the early universe was free of charge
NewScientist    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Most of us would find living without electricity almost impossible, but in the early universe electric charge was practically nonexistent. It turns out that the electric charge of fundamental particles could have been close to zero when the universe was fractions of a second old. It's all because of the action of gravity - a discovery that, if confirmed, could help pave the way for a unified description of physical reality. More

Hubble successor hit by budget setback
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
NASA boss Charles Bolden has announced sweeping changes to the management of the $5 billion James Webb Space Telescope (JWST) after an independent report called for the space agency to tackle budget overruns and delays to what is one of NASA's flagship missions. The report by the seven-member JWST review panel, chaired by John Casani from NASA's Jet Propulsion Laboratory, also says that the telescope will require an additional funding boost of $1.5 billion if it is to launch by late 2015.
