Tiny chip provides a big boost in precision optics

By merging two or more sources of light, interferometers create interference patterns that can provide remarkably detailed information about everything they illuminate, from a tiny flaw on a mirror, to the dispersion of pollutants ...

Laser light used to modulate free electrons into qubits

The laws of quantum physics are not only extraordinary—they also offer some far-reaching and unique possibilities for advanced information processing, quantum computing and cryptography. So far, the basic building blocks ...

NASA, USGS release first Landsat 9 images

Landsat 9, a joint mission between NASA and the U.S. Geological Survey (USGS) that launched Sept. 27, 2021, has collected its first light images of Earth.

Scientists discover how mitochondria import antioxidants

Many of the processes that keep us alive also put us at risk. The energy-producing chemical reactions in our cells, for example, also produce free radicals—unstable molecules that steal electrons from other molecules. When ...

Under pressure, 'squishy' compound reacts in remarkable ways

Remarkable things happen when a "squishy" compound of manganese and sulfide (MnS2) is compressed in a diamond anvil, say researchers from the University of Rochester and the University of Nevada, Las Vegas (UNLV).

The paradox of a free-electron laser without the laser

A new way of producing coherent light in the ultra-violet spectral region, which points the way to developing brilliant table-top X-ray sources, has been produced in research led at the University of Strathclyde.

Electrons in quantum liquid gain energy from laser pulses

The absorption of energy from laser light by free electrons in a liquid has been demonstrated for the first time. Until now, this process was observed only in the gas phase. The findings, led by Graz University of Technology, ...
