“#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…
“#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…
“#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…
“#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…
“#The smallest motor in the world” A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor is that it moves exactly at the boundary between classical…
“#A ‘pause button’ for light particles” Credit: Pixabay/CC0 Public Domain How do you stop something that is faster than anything else, intangible and always in motion by nature? A team led by physicists Dr. Thorsten Peters and Professor Thomas Halfmann is doing the seemingly impossible: stopping light for tiny fractions of a second. They then…
