“#Shhhh, the whales are resting” Credit: CC0 Public Domain We need new guidelines to shield whales from human-made noise to ensure them some peace and quiet. It is no good keeping whale-watching boats out of whales’ sight if the noise from the boats’ engines disturb the whales most. And whales can hear the boats’ engines…
“#Multicolor super-resolution imaging made easy” Credit: Ecole Polytechnique Federale de Lausanne Scientists at EPFL have developed robust and easy-to-implement multicolor super-resolution imaging. The approach is based on the simultaneous acquisition of two spectral channels followed by spectral cross-cumulant analysis and unmixing. They exploit fluorophore blinking and spectral crosstalk for the generation of additional color channels…
“#Huge forest fires put health at risk” Fire and smoke in Siberia in Summer 2019. Credit: Greenpeace Russia After Australia, Siberia is burning, indicating that the frequency of such events is on the rise, with myriad dire consequences: devastated ecosystems, risk of desertification, CO2 emissions, toxic particles, further climate impacts… An expert in atmospheric processes…
“#Wastewater treatment boom changes essential nutrient balance in lakes” Wastewater is proven to play the most significant role in causing the nitrogen/phosphorus changes in Chinese lakes. Imbalance of nutrient status may facilitate the growth of toxic cyanobacteria. Credit: Weijiang Chen A vast number of new wastewater treatment plants in developing countries has led to an…
“#Hurricane season combined with COVID-19 pandemic could create perfect storm” Credit: CC0 Public Domain When extreme climate conditions interact with stressors to social systems, such as the COVID-19 pandemic, the consequences could be severe unless experts from diverse backgrounds work together to develop comprehensive solutions to combat their negative impacts. That’s the recommendation of a…
“#If there is life out there, can we detect it?” Artist’s impression; the Cassini spacecraft sampling Enceladus’ ice plume. Credit: NASA/JPL-Caltech Instruments aboard future space missions are capable of detecting amino acids, fatty acids and peptides, and can even identify ongoing biological processes on ocean moons in our solar system. These are the exciting conclusions…
“#Scientists grow optical chips in a petri dish” Credit: Article’s authors The modern photonics industry is constantly working on making its devices more compact, be it computing systems or sensors and lidars. For this, it is necessary to make lasers, transistors and other elements smaller. A team of scientists led by ITMO researchers proposed a…
“#Need for better approaches to tackle multiple stressors in European lakes and rivers” Sampling related to MARS experiment in a mesocosm facility in Lake Stechlin, Germany. Credit: Anne Lyche Solheim/NIVA A newly released Nature paper highlights a continued management need for reduction of nutrient stress in lakes. It also shows that river management requires more…
“#A small protein transports electrons between the two photosystems involved in plant photosynthesis” Scanning electron microscope image of thylakoids – each circle is a high-rise building seen from above. Credit: Wanner/LMU The emergence of oxygenic photosynthesis made it possible for complex multicellular life-forms to evolve on Earth. By utilizing solar energy to turn carbon dioxide…
