Chemical Reviews published a comprehensive review on electron density-based methods, authored by an international team led by researchers from Japan, Canada, China, and the USA. This review highlights method based on the analysis of electron density topology, a theoretical chemistry concept with practical applications in understanding chemical bonds, reactions, and developing advanced computational materials science methods. The article emphasizes the role of these methods in advancing technology, particularly in electrochemical power sources like batteries. Recent advancements in methods combining electron density topology and machine learning are expected to revolutionize large-scale ab initio simulations.
In a new study,1 led by the University of Oxford’s Department of Physics and published today (18 November) in Nature, an international group of authors who developed the science behind net zero demonstrate that relying on ‘natural carbon sinks’ like forests and oceans to offset ongoing CO2 emissions from fossil fuel use will not actually stop global warming.
The science of net zero, developed over 15 years ago,2 does not include these natural carbon sinks in the definition of net human-induced CO2 emissions. Yet governments and corporations are increasingly turning to them to offset emissions, rather than reducing fossil fuel use or developing more permanent CO2 disposal options. Emissions accounting rules encourage this by creating an apparent equivalence between fossil fuel emissions and drawdown of CO2 by some natural carbon sinks, meaning a country could appear to have ‘achieved net zero’ whilst still contributing to ongoing warming.
SAN ANTONIO — November 18, 2024 —Southwest Research Institute is working to expand software normally used to model electrolytes and predict corrosion and turn it into a tool that can help determine whether ice-covered worlds have the right conditions for microbial life. The project is supported by NASA’s Habitable Worlds program, which seeks to use knowledge of the history of the Earth and the life upon it as a guide for determining the processes and conditions that create and maintain habitable environments.
Black holes expel powerful jets of charged particles that lead to luminous bursts of gamma rays, all made possible by each black hole’s intense surrounding magnetic field. Where this magnetic field comes from has remained a mystery, however — until now. Using calculations of black hole formation, scientists at the Flatiron Institute and their collaborators have found that the black hole’s magnetic field is inherited from their parents — highly magnetized remnants of the collapsing cores of exploded stars.
Research from Chalmers University of Technology, Sweden, shows that resistant bacteria can regain susceptibility to antibiotics when the treatment is combined with a material equipped with antibacterial peptides. The study, performed in a laboratory environment, shows that antibiotics can achieve a 64-fold increase in bactericidal effect when used together with the material, whose antibacterial properties are also greatly enhanced by this combination.
Recent research by a student-faculty team at Colgate University unlocks new clues that could radically change the world’s understanding of the origin of dark matter.
