“#A safe and powerful treatment for the body against deadly radiation” Schematic illustration of highly catalytic CeO2/Mn3O4 nanocrystals preventing acute radiation syndrome. Credit: IBS Despite the wide application of radiation in diagnostics and treatments, there is still no magic material to protect people from radiation exposure. Though Amifostine is developed as a radioprotectant, the FDA…
“#New nano-engineering strategy shows potential for improved advanced energy storage” Novel material nanoarchitecture enables the development of new-generation high-energy batteries beyond Li-ion chemistry Credit: University of Technology Sydney The rapid development of renewable energy resources has triggered tremendous demands in large-scale, cost-efficient and high-energy-density stationary energy storage systems. Lithium ion batteries (LIBs) have many advantages…
“#Long-term consequences of river damming in the Panama Canal” How has the Chagres River ecosystem changed since pre-Panama Canal times. Credit: Ian Cooke/Cooked Illustrations Humans have manipulated and managed rivers with dams for millennia. The number of river dam projects is predicted to rise sharply in the future, especially in the tropics where demand for…
“#Scientists synthesize novel artificial molecules that mimic a cell membrane protein” An unsymmetrical molecular structure allows for oriented insertion of the synthetic amphiphile to a bilayer by addition to a pre-formed membrane. Complexation with a ligand prompts ion transportation by forming a supramolecular channel, and removal of the ligand deactivates the transportation function. Credit: Tokyo…
“#Norovirus has two alternative capsid structures which change before infection” Credit: National Institutes of Natural Sciences Human noroviruses are a major cause of gastroenteritis outbreaks worldwide. They cause approximately 200,000 deaths each year in developing countries. However, no effective vaccine or antiviral agent for noroviruses yet exists because cell culture methods to produce noroviruses are…
“#Maryland’s signature fish is under assault from mercury pollution” Credit: CC0 Public Domain In late March, the U.S. Environmental Protection Agency announced it would stop enforcing many anti-pollution laws because of the COVID-19 pandemic. On Aug. 31, as the Trump administration recently announced, the EPA is ending its lax enforcement approach. But that might be…
“#Closing the gap: Citizen science for monitoring sustainable development” Credit: Unsplash/CC0 Public Domain Citizen science could help track progress towards all 17 UN Sustainable Development Goals (SDGs). An IIASA-led study, for the first time, comprehensively analyzed the current and potential contribution of citizen science data to monitor the SDGs at the indicator level. Huge amounts…
“#’Pregnancy test for water’ delivers fast, easy results on water quality” Tests glow green when they detect a contaminant. Credit: Northwestern University A new platform technology can assess water safety and quality with just a single drop and a few minutes. Likened to a pregnancy test, the handheld platform uses one sample to provide an…
“#Structural insights into Fe-S protein biogenesis” Crystal structure of the CIA targeting complex provides insights into Fe-S protein biogenesis. Credit: Friedrich Miescher Institute for Biomedical Research The cytosolic iron sulfur assembly (CIA) pathway is required for the insertion of Fe-S clusters into proteins, including many DNA replication and repair factors. Despite its essential cellular function,…
“#Endangered butterfly in San Diego County is the focus of a new protection effort” Credit: CC0 Public Domain Two environmental groups have filed a petition with the state asking it to provide more protection for a once-abundant butterfly that has seen its numbers fall precipitously in San Diego County and elsewhere in recent decades. The…
