Optical 'dog's nose' may hold key to breath analysis
University of Adelaide researchers are developing a laser system for fast, non-invasive, onsite breath analysis for disease, potentially enabling screening for a range of diseases including diabetes, infections and various ...
Light-induced magnetic waves in materials engineered at the atomic scale
A new study discovers how the sudden excitation of lattice vibrations in a crystal can trigger a change of the magnetic properties of an atomically-thin layer that lies on its surface.
Extreme lab at European X-ray laser XFEL is a go
The Helmholtz Senate has given the green light for the Association's involvement in the Helmholtz International Beamline (HIB), a new kind of experimentation station at the X-ray laser European XFEL in Hamburg, ...
Better memory with faster lasers
DVDs and Blu-ray disks contain so-called phase-change materials that morph from one atomic state to another after being struck with pulses of laser light, with data "recorded" in those two atomic states. ...
Focused energy of lasers breaks microscopic adhesion
Small objects tend to cling to everything. It's why parents dread hosting parties that involve confetti. It's why glitter is fun for crafts—until it finds its way onto everything else you touch.
Clues to inner atomic life from subtle light-emission shifts
Atoms absorb and emit light of various wavelengths. Physicists have long known that there are some tiny changes, or shifts, in the light that gets absorbed or emitted, due to the properties of the atomic nucleus.
NASA collaborates with DRS Technologies to create mid-infrared detector
NASA scientist Xiaoli Sun and his industry partner have created the world's first photon-counting detector sensitive to the mid-infrared wavelength bands—a spectral sweet spot for a number of remote-sensing ...
Images in the air: Researchers turn to femtosecond lasers
Sandia's Z machine receives funding aimed at fusion energy
A two-year, $3.8 million award has been received by Sandia National Laboratories and the University of Rochester's Laboratory for Laser Energetics (LLE) to hasten the day of low-cost, high-yield fusion reactions ...
How frequency combs have enhanced fundamental science research
It almost sounds like a riddle: What tool has transformed basic scientific research and led to new technologies in so many different fields—timekeeping, medical research, communications, remote sensing, ...
Supercomputer simulations pave the way towards compact terahertz sources with tunable wavelengths
Yet it has the potential for numerous applications. In Physical Review Letters, scientists at Jülich together with their international partners present a new concept that uses short-pulse lasers to expand ...
Future biosensors could be woven into clothes
Commonly used health tests, such as pregnancy and blood sugar tests, involve putting a drop of fluid on a test strip, which is infused with a substance designed to detect a specific molecule.
Photoacoustic approach shows potential to expand bioimaging's scope
A human skull, on average, is about 0.3 inches thick, or roughly the depth of the latest smartphone. Human skin, on the other hand, is about 0.1 inches, or about three grains of salt, deep.
Scientists film shock waves in diamond
Researchers have used ultra-short pulses of X-rays to film shock waves in diamonds. The study headed by DESY scientists opens up new possibilities for studying the properties of materials. Thanks to the extremely ...
