Glowing Crystals Can Detect, Cleanse Contaminated Drinking Water

Scientists Trace ‘Poisoning’ in Chemical Reactions to the Atomic Scale

3-D Imaging Technique Maps Migration of DNA-carrying Material at the Center of Cells

Image - This image shows the skeletonized structure of heterochromatin (red represents a thin region while white represents a thick region), a tightly packed form of DNA, surrounding another form of DNA-carrying material known as euchromatin (dark blue represents a thin region and yellow represent the thickest) in a mouse’s mature nerve cell.

Simulations Show Swirling Rings, Whirlpool-Like Structure in Subatomic ‘Soup’

Image - This hydrodynamic simulation shows the flow patterns, or “vorticity distribution,” from a smoke ring-like swirling fluid around the beam direction of two colliding heavy ions. The simulation provides new insight about the properties of a superhot fluid known as the quark-gluon plasma. (Credit: Berkeley Lab)

Crystal Clear Imaging: Infrared Brings to Light Nanoscale Molecular Arrangement

Image - Infrared light produced by Berkeley Lab's synchrotron (upper left) and a conventional laser (middle left) is combined and focused on the tip of an atomic force microscope (lower right), where it is used to measure nanoscale details in a crystal sample (dark red).

Construction of World’s Most Sensitive Dark Matter Detector Moves Forward

Photo - A cutaway rendering of the LUX-ZEPLIN (LZ) detector that will be installed nearly a mile deep near Lead, S.D. The central detector will be filled with 10 metric tons of purified liquid xenon that produces flashes of light and electrical pulses in particle interactions. An array of detectors, known as photomultiplier tubes, are designed to amplify and measure these particle signals. (Credit: Matt Hoff/Berkeley Lab)

Scientists Find Twisting 3-D Raceway for Electrons in Nanoscale Crystal Slices

Photo - A scanning electron microscope image shows triangular (red) and rectangular samples of a semimetal crystal known as cadmium arsenide. The rectangular sample is about 0.8 microns (thousandths of a millimeter) thick, 3.2 microns tall and 5 microns long. The triangular sample has a base measuring about 2.7 microns. The design of the triangular samples, fabricated at Berkeley Lab’s Molecular Foundry, proved useful in mapping out the strange electron orbits exhibited by this material when exposed to a magnetic field.

A Conscious Coupling of Magnetic and Electric Materials

Teams of Scientists Gather at Berkeley Lab to Study Secrets of Plants’ Plumbing

Photo - Thorsten Knipfer, a UC Davis postdoctoral researcher, carries an American chestnut sapling into the experimental chamber at Berkeley Lab’s Advanced Light Source. Knipfer and other researchers used X-rays at ALS Beamline 8.3.2 to scan the stems of dozens of saplings. The work will produce 3-D reconstructions of the stems’ microscopic structure.
