“#Geoengineering’s benefits limited for apple crops in India” A map of India, with apple-growing regions in color. Himachal Pradesh is the second-largest apple-producing state in India. Credit: Jyoti Singh Geoengineering—spraying sulfur dioxide into the atmosphere to combat global warming—would only temporarily and partially benefit apple production in northern India, according to a Rutgers co-authored study….
“#Extinction Rebellion’s activists more likely to be new to protesting, study shows” Credit: Joël de Vriend/Unsplash (licensed under CC.0) Extinction Rebellion supporters are more likely to be new to protesting than other environmental activists, a new study shows. Ten per cent of those who took part in the group’s protests in April 2019 were first-time…
“#New chemical analyses: What did Danes and Italians in the Middle Ages have in common?” The Montella Chapel near Naples, southern Italy, was built in the 1620s when Giovanni Bernardino Iannelli donated a large sum to the monastery. It has been excavated since 2007. Credit: University of Southern Denmark In the 1600s, two private chapels…
“#Rsearchers suggest modification of quantum encryption system with compact detector” Credit: Bruno Thethe on Unsplash A new system can significantly lower the production costs costs of mass quantum key distribution (QKD) networks, which will make them available to a wider user audience. This will make it possible to use QDK in the regular fiber-optic cable…
“#The force necessary to kill a single bacterium” Simultaneous AFM nanoindentation and fluorescence imaging of E. coli. Credit: Patricia Bondía Antibiotic resistance is one of the biggest threats to global health and food security today according to the World Health Organization. This process occurs naturally, but misuse of antibiotics in humans and animals is accelerating…
“#Data analytics can predict global warming trends, heat waves” Early warning signals as increasing autocorrelation coefficient and standard deviation prior to the early 20th century global warming (left) and mega heat wave during 2010 in Russia (right). Credit: Chenghao Wang, Stanford University New research from Arizona State and Stanford Universities is augmenting meteorological studies that…
“#Twisting magnetic fields for extreme plasma compression” Post-implosion images of the plasma cylinders. On the left, plasma tentacles stretch out from the sides of the conventional, straight-column design. With the 14-tesla and 20-tesla twisted structures in the middle and right, respectively, the plasma tentacles are much shorter. This reflects more uniform compression by the magnetic…
“#Bacteria with a metal diet discovered in dirty glassware” Manganese oxide nodules generated by the bacteria discovered by the Caltech team. The nodules are generally about 0.1 to 0.5 millimeters in diameter. Images are scanning electron micrographs with false colorization. Credit: Hang Yu/Caltech Caltech microbiologists have discovered bacteria that feed on manganese and use the…
“#Scientists uncover key process in the manufacture of ribosomes and proteins” Negin Khosraviani, Karim Mekhail and Karan (Josh) Abraham. Credit: University of Toronto Researchers at the University of Toronto have shown that an enzyme called RNA polymerase (Pol) II drives generation of the building blocks of ribosomes, the molecular machines that manufacture all proteins in…
“#Nano-polycatenane synthesis achieved with molecular self-assembly” Atomic Force Microscopy (AFM) images of poly[22]catenane, the longest polycatenane created by the research group (top) and five interlocked rings in a linear arrangement similar to the Olympic Games symbol (bottom) Credit: Shiki Yagai An international research group led by Chiba University Professor Shiki Yagai has for the first…
