What resembles a donut or the iris of an eye is actually a liquid cell illuminated from below.


Part of the Chemo-Hydrodynamic Patterns and Instabilities (CHYPI) experiment that recently flew on the 73rd ESA parabolic flight campaign, this cell has a lot to offer the chemical solutions industry.

Researchers behind CHYPI are seeking to validate a theoretical model, developed by Anne De Wit and her team at the Université Libre de Bruxelles, to control the formation of new chemical products.

To do this, they needed to understand the flow reactions of chemical liquids in gravity and microgravity conditions, so they took to the skies for an extraordinary parabolic flight campaign that was adjusted to COVID-19 safety measures.

The science team from Helmholtz-Zentrum Dresden-Rossendorf and TU Dresden mixed two reactant solutions in a liquid cell, creating a red-brown ferric thiocyanate solution. They found, that under

The birds have variable migration strategies — ScienceDaily

Through a large-scale study with so-called geolocators, researchers led by Miriam Liedvogel of the Max Planck Institute for Evolutionary Biology in Plön, Germany, were able to uncover some of the mysteries surrounding the phenomenon of the blackcap’s bird migration.

Many species of birds have always migrated south in the fall to spend the winter there, including the small blackcap, which often weighs only a few grams and yet covers thousands of kilometers. However, changes in our landscapes and climate change are not leaving migratory birds unaffected. They change their behavior, the destinations of their journey, the time of their departure or even the decision whether to fly away at all. So far, these habits have been studied either experimentally with birds in captivity or by irregular recaptures of ringed birds.

A group of international researchers led by Miriam Liedvogel from the Max Planck Institute for Evolutionary Biology in Plön has

Higher death, hospitalization rates compared to non-white Hispanic individuals, variable by race — ScienceDaily

Results from a new study led by Boston Medical Center (BMC) demonstrate the disproportionate impact of COVID-19 on Hispanic groups within the US, with the most severe outcomes, including death and intensive care, among Hispanic Black individuals. Analyzing data from the Centers for Disease Control and Prevention, researchers found differences between Hispanic groups, with higher rates of hospitalization and increased risk of death for Hispanic Black compared to Hispanic multiracial individuals. Published online in the Journal of Immigrant and Minority Health, the results highlight that Hispanic populations as a whole have worse COVID-19 outcomes compared to the Hispanic white population, demonstrating the need for more accurate demographic data collection efforts in order to better address the disparities among Hispanic individuals impacted by COVID-19.

Results from previous COVID-19 research have shown that Latinx populations, as a whole, have worse outcomes compared to other ethnic groups. This study, the first to
