Bold Move Forward in Molecular Analyses
New metrics for analyzing data from small angle scattering (SAS) experiments should dramatically improve the ability of scientists to study the structures of macromolecules such as proteins and nanoparticles in solution.
In the Blink of an Eye: X-ray Imaging on the Attosecond Timescale
In the blink of an eye, more attoseconds have expired than the age of Earth measured in – minutes. A lot more. To be precise, an attosecond is one billionth of a billionth of a second. The attosecond timescale is where you must go to study the electron action that is the starting point of [...]
A Closer Look at Life: X-ray Microscopy Hits the Sweet Spot for Chemical and Elemental Imaging
In perhaps no other scientific field does the adage “form follows function” hold more true than in biology, especially the biology of living cells, which is why our knowledge of cells starts with imaging. Optical microscopy is limited by low spatial resolution – about 200 nanometers, and electron microscopy is limited by the poor penetration [...]
Berkeley Lab Sensors Enable First Light for the Dark Energy Camera
Mounted on a telescope high in the Andes, the Dark Energy Camera (DECam) saw first light September 12. DECam’s half-billion-pixel focal plane is made of Berkeley Lab CCDs, descended from sensors developed for high-energy physics by Berkeley Lab scientists and engineers. Highly sensitive to the near-infrared region of the spectrum, Berkeley Lab CCDs are an essential component of the most powerful dark-energy survey instrument yet made.
Synchronized Lasers Measure How Light Changes Matter
How matter responds to light lies at the core of vision, photosynthesis, solar cells and light-emitting diodes, and many other fields of scientific and practical import. But until now, it hasn’t been possible to see just how light does it. Berkeley Lab scientists have used SLAC’s Linac Coherent Light for the first demonstration that x-ray and optical wave mixing reveals not only structure but evolving charge states on the atomic scale.
