“#An analysis of the system-wide costs and benefits of using engineered nanomaterials on crop-based agriculture” Credit: CC0 Public Domain A team of researchers affiliated with several institutions in the U.S. has conducted an analysis of the system-wide costs and benefits of using engineered nanomaterials (ENMs) on crop-based agriculture. In their paper published in the journal…
“#Experiment shows it is possible for fish to migrate via ingestion by birds” Credit: Pixabay/CC0 Public Domain A team of researchers from the Danube Research Institute and the National Agricultural Research and Innovation Centre, both in Hungary, and Estación Biológica de Doñana, Consejo Superior de Investigaciones Científicas in Spain reports that is it possible for…
“#Experimental peptide targets COVID-19” Colorized scanning electron micrograph of an apoptotic cell (pink) heavily infected with SARS-COV-2 virus particles (green). MIT researchers are using computational models of protein interactions to design a peptide that can bind to coronavirus proteins and shuttle them into a cellular pathway that breaks them down.

He had a bladder infection, but instead of receiving treatment, remained in the waiting room for 34…
“#Growing polymers with different lengths” Symbolic representation of how the dispersity of a plastic can be controlled by mixing two catalysts (paint tubes). Credit: Whitfield R et al, Chem, 2020 ETH researchers have developed a new method for producing polymers with different lengths. This paves the way for new classes of polymer materials to be…
“#Did a volcanic eruption in Alaska help end the Roman republic?” Julius Caesar was assassinated on the Ides of March (March 15) in 44 BC and a bloody civil war followed. This brought down the Roman republic and replaced it with a monarchy led by Caesar’s nephew Octavian, who in 27 BC became the emperor…
“#Dawn song of the male great tit attracts other males rather than females” Credit: Pixabay/CC0 Public Domain Female great tits (Parus major) stay clear of territories with better singing males while competing males are attracted to the territories with better singers. This unexpected conclusion was reached by researchers of Wageningen University & Research in collaboration…
“#Fifty perfect photons for ‘quantum supremacy’” Credit: University of Twente Fifty is a critical number for quantum computers capable of solving problems that classic supercomputers cannot solve. Proving quantum supremacy requires at least 50 qubits. For quantum computers working with light, it is equally necessary to have at least 50 photons. And what’s more, these…
“#’Unboil an egg’ machine creates improved bacteria detector” Credit: Pixabay/CC0 Public Domain Traditional fluorescent dyes to examine bacteria viability are toxic and suffer poor photostability—but using the VFD has enabled the preparation of a new generation of aggregation-induced emission dye (AIE) luminogens using graphene oxide (GO), thanks to collaborative research between Flinders University’s Institute for…
“#Lizards need their coffee, too: Could caffeine help bring threatened species back from the brink?” Credit: Pixabay/CC0 Public Domain In an article just published in Conservation Physiology, Macquarie University’s Simon Clulow and colleagues reveal a new sperm freezing and revival technique that shows considerable promise—and involves a surprising ingredient. The group took sperm from a…
