New picture of atomic nucleus emerges

March 1, 2012 9:12 am | News | Comments

When most of us think of an atom, we think of tiny electrons whizzing around a stationary, dense nucleus composed of protons and neutrons, collectively known as nucleons. A collaboration between the U.S. Department of Energy's Argonne National Laboratory and Thomas Jefferson National Accelerator Facility has demonstrated just how different reality is from our simple picture.

Big, bad bacterium is an 'iron pirate'

February 21, 2012 3:53 am | News | Comments

Life inside the human body sometimes looks like life on the high seas in the 1960s, when pirates hijacked foreign vessels in search of precious metals. For Neisseria bacteria, which can cause gonorrhea and meningitis, the booty is not gold or silver but plain old iron. Until recently, scientists did not understand how these bacterial snatch iron from healthy human cells, where a protein called transferrin bind the metal in a molecular bear hug.

Small modular reactor design could be a SUPERSTAR

February 9, 2012 8:21 am | News | Comments

Though most of today's nuclear reactors are cooled by water, we've long known that there are alternatives; in fact, the world's first nuclear-powered electricity in 1951 came from a reactor cooled by sodium. Reactors cooled by liquid metals such as sodium or lead have a unique set of abilities that may again make them significant players in the nuclear industry. Argonne National Laboratory has designed a new small reactor cooled by lead.
