A nanocrystal shines on and off indefinitely
May 31, 2023 (Nanowerk News) In 2021, lanthanide-doped nanoparticles made waves—or rather, an avalanche—when Changwan Lee, then a PhD student in Jim Schuck’s lab at Columbia Engineering, set off an extreme light-producing chain reaction from ultrasmall crystals developed at the Molecular Foundry at Berkeley Lab. Those same crystals are back again with a blink that…

A team has discovered how the influenza A virus hijacks the mechanism for importing iron into cells to invade its host — ScienceDaily
Influenza epidemics, caused by influenza A or B viruses, result in acute respiratory infection. They kill half a million people worldwide every year. These viruses can also wreak havoc on animals, as in the case of avian flu. A team from the University of Geneva (UNIGE) has identified how the influenza A virus manages to…

Plants can distinguish when touch starts and stops, study suggests — ScienceDaily
Even without nerves, plants can sense when something touches them and when it lets go, a Washington State University-led study has found. In a set of experiments, individual plant cells responded to the touch of a very fine glass rod by sending slow waves of calcium signals to other plant cells, and when that pressure…

Color-changing material shows when medications get too warm — ScienceDaily
Some foods and medicines, such as many COVID-19 vaccines, must be kept cold. As a step toward a robust, stable technique that could indicate when these products exceed safe limits, researchers in ACS Nano report a class of brilliantly colored microcrystals in materials that become colorless over a wide range of temperatures and response times.…

Could a moderate protein diet be the coveted elixir of youth? Researchers decode the correlation between dietary protein intake and improved metabolic health in mice — ScienceDaily
Consuming nutritious food can improve metabolic health and delay aging. But what are the appropriate quantities of dietary macronutrients that can help achieve this? To answer this, researchers from Japan fed isocaloric diets with varying amounts of protein to young and middle-aged male mice. They found that the mice were metabolically healthier when fed moderate-protein…

Israeli astrophysicists may have solved the mystery of early galaxies
The mystery of the formation of early massive galaxies in the universe has finally been solved by astrophysicists from the Hebrew University of Jerusalem (HU) who have published a new theoretical model that explains recent observations that used the James Webb Space Telescope (JWST). They said they revealed a surprising excess of massive galaxies in…
