A figure in red trudges across a blanket of white. Snow squeaks under the scientist's feet, too dry to be slick or soft. Only a line of flags and a few large buildings—the scientist's destination—break up the landscape.
The sun hovers on the horizon, never quite setting against a blue sky devoid of clouds.

The wasps that horrified Darwin reveal evolution's one-way streets
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

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-

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

New method measures microplastics in the air using an uncrewed aerial system
Microplastics have been found in our bodies and the food we eat—and even in remote environments around the world, including seawater and ice in the Arctic. Despite their prevalence, little is known about how they move through the atmosphere. New CIRES-led research, which demonstr
