“#How to tackle climate change, food security and land degradation” A farmer tends rice fields in Yen Bai, Vietnam, where balancing goals for sustainable development and management of ecosystems is challenging. Options like improved cropland management, increasing soil carbon, agroforestry, integrated water management and fire management are all low trade-off land management practices that can…
“#Aggressive seaweed smothers one of world’s most remote reefs” In this Aug. 4, 2019 photo provided by Taylor Williams, a new species of seaweed covers dead a coral reef at Pearl and Hermes Atoll in the remote Northwestern Hawaiian Islands. Researchers say the recently discovered species of seaweed is killing large patches of coral on…
“#Shock-dissipating fractal cubes could forge high-tech armor” Simulations show how fractal structures of increasing complexity dissipate energy from shockwaves. Credit: Los Alamos National Laboratory Tiny, 3-D printed cubes of plastic, with intricate fractal voids built into them, have proven to be effective at dissipating shockwaves, potentially leading to new types of lightweight armor and structural…
“#Scientists observe catalyst during Fischer-Tropsch synthesis for the first time” Test setup including high-pressure cell for the Fischer-Tropsch measurement campaign using the CAT-ACT measurement line at the KIT synchrotron. Credit: Tiziana Carambia Suitable catalysts are of great importance for efficient power-to-X applications—but the molecular processes occurring during their use have not yet been fully understood….
“#Forbidden herbs? The effects of cannabis were a controversial topic 250 years ago” Jacobus Tabernaemontanus: “Neuw vollkommentlich Kreuterbuch.” First edition 1588. Credit: University of Tübingen Should cannabis be legalized for medicinal purposes or will it remain an illegal drug? This has been discussed in many countries for years—and has been a point of contention for…
“#Physicist optimizes DNA microscopy technique to improve imaging speed, add color” Credit: S. Strauss/MPI of Biochemistry Super-resolution fluorescence microscopy can be used to visualize structures smaller than 200 nanometers, i.e., below the diffraction limit of light. One of the microscopy techniques, called DNA-PAINT, was developed by Ralf Jungmann, research group leader at the MPI of…
“#Using sound to study underwater volcanoes” The Hawaiian-Emperor seamount chain (the roughly L-shaped configuration near the center of the image) is about 3,900 miles long. For comparison, that’s the west coast of North America on the right. Credit: NOAA Imagine placing a rock on a piece of suspended cardboard. If the cardboard is strong and…
“#Scientists introduce new method for machine learning classifications in quantum computing” A quantum circuit for implementing the non-linear kernel-based binary classification. Credit: KAIST Quantum information scientists have introduced a new method for machine-learning classifications in quantum computing. The non-linear quantum kernels in a quantum binary classifier provide new insights for improving the accuracy of quantum…
“#Making a list of all creatures, great and small” Reticulated giraffe Giraffa (camelopardalis) reticulata, photographed in Kenya in 2013. Giraffe taxonomy is being debated, with the traditional classification recognizing a single species and other classifications recognizing up to eight distinct giraffe species. On the former view, the Reticulated giraffe would be a subspecies, on the…
“#Predicting fire risk” Oak Ridge National Laboratory developed a method that uses machine learning to predict seasonal fire risk in Africa, which contains about 70% of the global burned area, shown in red. Credit: NASA Researchers at Oak Ridge National Laboratory developed a method that uses machine learning to predict seasonal fire risk in Africa,…
