4-Feb-2015 Record keeping helps bacteria's immune system fight invaders
Bacteria have a sophisticated means of defending themselves, and they need it: more viruses infect bacteria than any other biological entity. Two experiments undertaken at the Department of Energy's SLAC National Accelerator Laboratory provide new insight at the heart of bacterial adaptive defenses in a system called CRISPR, short for Clustered Regularly Interspaced Short Palindromic Repeat.
2-Feb-2015 Five ways to put tiny targets in front of an X-ray laser
X-ray devices have long been used to see the inner structure of things, from bone breaks in the human body to the contents of luggage at airport security checkpoints. But to see life's chemistry and exotic materials at the scale of individual atoms, you need a far more powerful X-ray device. Enter the Linac Coherent Light Source X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory.
2-Feb-2015 The quest for efficiency in thermoelectric nanowires
