UCLA researchers have produced the clearest 3-D images to date of the virus that causes cold sores, herpes simplex virus type 1, or HSV-1. The images enabled them to map the virus’ structure and offered new insights into how HSV-1 works. A report on the research was published online by the journal Science. The scientists used cryo electron microscopy, or cryoEM, to obtain the first atomic model of the virus particle, which is made up of more than 3,000 protein molecules comprising tens of millions of atoms.

So Ginsberg and her colleagues devised a measurement that transforms an optical “super-resolution” microscopy known as STED (stimulated emission depletion) into a tracker of excitons on these short scales in an organic semiconductor. The technique makes it possible, for the first time, to relate the characteristics of exciton migration efficiency to nanoscale structures within light harvesting materials. “We ended up using the spatial profile of light pulses and the way that they interact with the material in order to excite very small and localized regions that have very sharp boundaries,”...

Professor Shimon Weiss leads team to develop nanosensors that can be directly inserted into a cell’s lipid membrane and be used to measure membrane potential. The devices, which are based on inorganic semiconductor nanoparticles, could potentially record action potentials from multiple neurons as well as electrical signals on the nanoscale – for example, across just one synapse. Their paper, "Membrane insertion of—and membrane potential sensing by—semiconductor voltage nanosensors: Feasibility demonstration” was published in the January, 12, 2018 issue of Science...

Electron oscillations in silicon may be used to map, with nanometer resolution, the temperatures across a silicon device. Chris Regan of the University of California, Los Angeles, and co-workers have now developed a thermometry technique that, using a scanning transmission electron microscope (STEM), could eventually map temperature in a silicon device with a resolution down to 10 nm.

The U.S. is losing ground in a second laser revolution of highly intense, ultrafast lasers that have broad applications in manufacturing, medicine, and national security, says a new report from the National Academies of Sciences, Engineering, and Medicine. Currently, 80 percent to 90 percent of the high-intensity laser systems are overseas, and all of the highest power research lasers currently in construction or already built are overseas as well. The report makes five recommendations that would improve the nation’s position in the field, including for the U.S.... Read More

Tabletop coherent EUV/SXR beams are now possible using high-harmonic generation (HHG).1,2 In addition, a new generation of powerful coherent-diff ractiveimaging (CDI) techniques is removing the resolution limits imposed by traditional X-ray microscopy, by replacing lossy and imperfect X-ray optics with powerful iterative phase retrieval algorithms.

In her Symposium X talk on Monday, Margaret Murnane of the University of Colorado Boulder described methods to create coherent sources with extremely short wavelengths, with excellent spectral, temporal, and polarization control. “Thirty years ago,” she said, “we never thought that we could achieve the same kind of control—and perhaps better control—over light in extreme UV and soft x-ray region as we could in the visible region of the spectrum.”

From life-saving advances in medicine to life-changing opportunities in renewable energy, imaging technology offers a window into worlds that can’t otherwise be seen by the human eye. That makes it an essential tool across a broad range of scientific disciplines, from engineering to biosciences. But despite their widespread use, today’s imaging techniques remain limited. Finding a solution to this problem will require collaborating with other institutions and developing new ways to educate up and-coming scientists. Based at CU Boulder, the Science and Technology Center on Real-Time... Read More

Ever since the invention of the laser more than 50 years ago, scientists have been striving to create an X-ray version. But until recently, very high power levels were needed to make an X-ray laser. Making a practical, tabletop-scale X-ray laser source required taking a new approach, as will be described by physicist Margaret Murnane in this fall’s Hans Bethe Lecture.
