Heavy rain can more than double glacier speeds in Alaska

Glaciers are often thought of as unyielding blocks of ice that slowly carve out the landscape as they move downhill by gravity. But sometimes their slow crawl becomes a surge that sees them move orders of magnitude faster than their usual speed.

The wasps that horrified Darwin reveal evolution

Few insects have a more gruesome lifestyle than Darwin wasps. Rather than simply hunting other animals, these parasitic wasps lay their eggs on or inside living hosts, including caterpillars, beetles and spiders. Their larvae then feed on their hosts, gradually consuming them and eventually killing them.

Air holes turn silicon wafers into flat ultraviolet focusing mirrors for compact optics

Traditional lenses and mirrors focus light using curved surfaces. Metasurfaces can achieve similar functions with a flat layer of nanoscale structures that locally control the phase of light. Extending these flat optics into the ultraviolet could support compact systems for high-resolution imaging, spectroscopy, and sensing, but it introduces a fundamental materials problem: many of the materials used to make metasurfaces strongly absorb UV light.

How a metabolite protects the enzyme that consumes it

Metabolites are consumed by enzymes to produce other vital molecules as well as to control metabolite levels. But how do cells avoid consuming too much? Researchers from the MPI of Biochemistry, with the University of Nevada, Las Vegas, and the de Duve Institute in Brussels, have deciphered such molecular regulation in tryptophan metabolism. The essential amino acid tryptophan binds to a second site on the enzyme TDO2, distinct from where it is consumed. This sequesters a region needed by two ef

Smart packaging film

Food spoilage causes chemical changes that are not always easy to detect by appearance alone. To provide a clearer indication of freshness and quality, researchers at Kyushu University have developed a smart packaging film that changes color and glows under ultraviolet (UV) light as meat loses freshness. Tested with refrigerated mutton, the film responds to compounds released during spoilage, offering two ways to track changes in food quality. The findings are published in the Chemical Engineeri

Vibrating mirrors of light create analog of a black hole event horizon

Optical cavities are pairs of light-trapping mirrors and underpin the operation of lasers, atomic clocks and many types of precision sensors. If the distance between the mirrors is changed rapidly enough, some theories predict that the waves inside them should bunch together into short, intense pulses. So far, however, this prediction has never been tested directly.
