Published New study unveils how plants control the production of reactive oxygen species
(via sciencedaily.com) Original source Reactive oxygen species (ROS), though generally regarded as toxic byproducts of biological processes, serve many important functions in plants. However, the precise mechanism that plants use to regulate the production of ROS remains elusive. In a recent study, researchers clarified how an important ROS-generating enzyme is activated, revealing mechanisms likely conserved across all land plants. Their findings could pave the way for breakthroughs in agricultural and environmental remediation tools.
Published Neutrons reveal 'atomic rings' and help predict glass performance
(via sciencedaily.com) Original source Researchers found that understanding the stability of the rings of atoms in glass materials can help them predict the performance of glass products. This capability is important because the most widely used glass is silicate glass, which consists of different sizes of atomic rings connected in three dimensions.
Published Water, water everywhere and now we may have drops to drink
(via sciencedaily.com) Original source Researchers have achieved a major breakthrough in Redox Flow Desalination (RFD), an emerging electrochemical technique that can turn seawater into potable drinking water and also store affordable renewable energy.
Published Major climate benefits with electric aircraft
(via sciencedaily.com) Original source Researchers have performed the world's first life cycle assessment (LCA) of an existing, two-seater, all-electric aircraft, with a direct comparison to an equivalent fossil fuel-powered one. According to the study, after just one quarter of the expected lifespan of the electric aircraft, the climate impact is lower than that of the fossil fuel-based aircraft, provided that green electricity is used. The downside, however, is increased mineral resource scarcity.
Published New sustainable method for creating organic semiconductors
(via sciencedaily.com) Original source Researchers have developed a new, more environmentally friendly way to create conductive inks for use in organic electronics such as solar cells, artificial neurons, and soft sensors. The findings pave the way for future sustainable technology.
