“#Strainoptronics: A new way to control photons” Artistic representation of a strain engineered 2D photodetector on silicon photonic circuit. Credit: George Washington University Researchers discovered a new way to engineer optoelectronic devices by stretching a two-dimensional material on top of a silicon photonic platform. Using this method, coined strainoptronics by a team led by George…

“#Parallel evolution in three-spined sticklebacks” The three-spined stickleback (Gasterosteus aculeatus), a thumb-sized fish distributed across the Northern hemisphere, is a textbook model species in evolutionary biology. Credit: Petri Kuokka A group of researchers from the University of Helsinki used novel and powerful methods to disentangle the patterns of parallel evolution of freshwater three-spined sticklebacks at…
“#300-million-year-old fish resembles a sturgeon but took a different evolutionary path” A re-examination of a 300-million-year-old fish, Tanyrhinichthys mcallisteri, revealed that its lifestyle more closely resembled that of the bottom-dwelling sturgeon, rather than the stealthy pike, as was previously believed. University of Pennsylvania researchers, led the study of the “enigmatic and strange fish.” Credit: Nobu…
“#Recovery from airline delays works best with future disruptions in mind” Industrial and enterprise systems engineering professor Lavanya Marla and her colleagues developed a new approach to airline-disruption recovery that could save the industry millions of dollars.

“#Enhanced secondary haze by emission reduction during COVID-19 lockdown in China” Credit: CC0 Public Domain As one of the first epicenters of this disease, China announced the most efficient prevention measures to slow down the spread of COVID-19 by restricting the movement of populations nationwide after the Chinese New Year 2020, which caused tremendous economic…
“#Southwestern correctional facilities’ drinking water puts inmate health at risk” Credit: CC0 Public Domain The first nationwide analysis of drinking water quality in United States correctional facilities found average arsenic concentrations in drinking water in Southwestern United States correctional facilities were twice as high as average arsenic concentrations in other Southwest community drinking water systems….
“#Highly modular metal-organic framework-based materials show great potential for photocatalytic hydrogen production” The metal-organic framework (gray and magenta lattice) can use solar energy to split water molecules (red and light blue spheres) to release hydrogen (light blue spheres). Credit: 2020 Nikita Kolobov A metal organic framework (MOF)-based water splitting photocatalyst, developed at KAUST, has brought…
“#TRACERS heliophysics mission enters Phase B” Two NASA sounding rockets carrying SwRI-developed ion instruments studied the electrodynamics of the polar cusp. The instruments will fly on TRACERS, a heliophysics mission to study how the Earth’s and Sun’s magnetic fields interact, set to launch in 2023.

“#Quantifying creativity to expand it? Better art begins with better understanding” Color materials enhance Children’s creativity. Credit: JAIST Do different painting materials affect the creation of children’s paintings? How might we increase children’s focus and motivation to learn, while also improving their creativity? Researchers focusing on these very questions at the Japan Advanced Institute of…
