DOI: 10.1021/acsnano.4c02656 UC Irvine-led research reveals that the optical properties of materials can be dramatically enhanced—not by changing the materials themselves, but by giving the light new properties. The researchers demonstrated that by manipulating the momentum of incoming photons, they could fundamentally change how light interacts with matter. One striking example … Read more

Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tested models for how these peptides are made and demonstrated how this information … Read more

DOI: 10.1038/s41596-024-01046-3 A research team led by scientists at the University of California, Riverside, has developed a computational workflow for analyzing large data sets in the field of metabolomics, the study of small molecules found within cells, biofluids, tissues, and entire ecosystems. Most recently, the team applied this new computational tool … Read more

Porous Si3N4 ceramics with uniform and fine structures were achieved by the dual-solvent templating combined freeze-casting method. Credit: Journal of Advanced Ceramics, Tsinghua University Press Radomes and wave-transmitting antenna windows are critical structural components in aircraft, protecting radar antennas from external interference while ensuring reliable communication. Currently, the most widely used wave-transmitting materials are ceramics … Read more

University of Delaware associate professor Andrew Wozniak co-led a research cruise aboard UD’s Research Vessel Hugh R. Sharp to study the sea surface microlayer in the North Atlantic Ocean. Pictured here are researchers working with a Rosette sampler, a device used for water sampling in deep water, outfitted with pieces of glass. These glass panels … Read more

At least 24 Cape fur seals … Read more

In 2020, more than 90 percent of plastic waste ended up in landfills or was incinerated, and only seven percent was recycled, according to the Canadian environment ministry. One of the largest producers of plastic waste per capita, Canada is struggling to protect its designated marine protected areas from this pollution, experts warn. Here are … Read more

Credit: Mariia Klymenko (Vienna) Birds of a feather flock together but strong pairing in geese has been shown to produce better breeding results, according to a new study. Focusing on a group of captive greylag geese, bird behavior experts from the University of Vienna and Flinders University have looked into the parental benefits of ‘made … Read more

Credit: Pixabay/CC0 Public Domain Iron is a micronutrient indispensable for life, enabling processes such as respiration, photosynthesis, and DNA synthesis. Iron availability is often a limiting resource in today’s oceans, which means that increasing the flow of iron into them can increase the amount of carbon fixed by phytoplankton, with consequences for the global climate. … Read more
