Carbon-busting hemp could help transform Scottish agriculture to zero emissions
Hemp is one of the oldest traded plants in the world, and cultivation in Scotland started as far back as the 11th century. Historically, cannabis—the name of the plant from which hemp is derived—was used to produce rope, cloth, lighting oil and m.....»»
Sustainable metal-recycling method reduces cost and greenhouse gas emissions
A research team led by Rice University's James Tour has developed a method to recycle valuable metals from electronic waste more efficiently while significantly reducing the environmental impact typically associated with metal recycling......»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
Shrinking augmented reality displays into eyeglasses to expand their use
Augmented reality (AR) takes digital images and superimposes them onto real-world views. But AR is more than a new way to play video games; it could transform surgery and self-driving cars. To make the technology easier to integrate into common perso.....»»
Morphology study paves the way for spider fang-inspired cutting tools
When we think of spiders, the first thing that comes to mind is their ability to weave intricate and robust webs. But their ability to cut their own silk—the toughest natural material—and strong or tough synthetic fibers such as carbon or Kevlar,.....»»
Study shows virtual reality may help pedestrians and cyclists avoid harmful pollutants
Physics-informed virtual reality could be key to reducing the exposure of pedestrians and cyclists to harmful, non-exhaust vehicle emissions, according to a study published 25 Sep in the Royal Society Open Science journal......»»

Atmospheric methane increase during pandemic due primarily to wetland flooding, satellite data analysis finds
A new analysis of satellite data finds that the record surge in atmospheric methane emissions from 2020 to 2022 was driven by increased inundation and water storage in wetlands, combined with a slight decrease in atmospheric hydroxide (OH). The resul.....»»
"Writing" with atoms could transform materials fabrication for quantum devices
A new technology to continuously place individual atoms exactly where they are needed could lead to new materials for devices that address critical needs for the field of quantum computing and communication that cannot be produced by conventional mea.....»»
Low-temperature ammonia-to-hydrogen conversion achieved by applying an electric field
Hydrogen gas, owing to its high energy density and carbon-free nature, is gaining much attention as the energy source for a green and sustainable future. Despite being the most abundant element in the universe, hydrogen is mostly found in a bound sta.....»»
Discovering new energy levels in atomic hyperfine structures
Since the late 1960s, the Laboratoire Aimé Cotton (LAC) in Orsay, France, has made significant progress in the classification of complex atomic spectra. These advances have been driven both by the development of Fourier transform spectroscopy, and t.....»»
Evaluating changes in dissolved inorganic carbon in the Greenland Sea
To know whether we are complying with emission treaties, all CO2 must be traceable. Incomplete bookkeeping recently sent scientists on a search in the Greenland Sea. Their research is published in the Journal of Geophysical Research: Oceans......»»
Graphene at 20: Still no sign of the promised space elevator, but the material is quietly changing the world
Twenty years ago this October, two physicists at the University of Manchester, Andre Geim and Konstantin Novoselov, published a groundbreaking paper on the "electric field effect in atomically thin carbon films." Their work described the extraordinar.....»»
Transforming agriculture from carbon source to sink: Study shows potential of carbon sequestration options
The food system is one of the most significant sources of greenhouse gas emissions on the planet, making the reduction of emissions in this sector a priority for policymakers around the world. IIASA researchers explored the potential of carbon seques.....»»
California carbon emissions lag behind 2030 climate targets, data show
California carbon emissions are falling, but not fast enough to reach the state's 2030 climate targets, according to data released Friday by the Air Resources Board. Leaders predicted that new and existing industry regulations would put the state on.....»»

European Green Deal is a double-edged sword for global emissions, analysis suggests
The European Union aims to be carbon-neutral by 2050 as part of the comprehensive Green Deal that was agreed upon four years ago. However, an analysis of the policy documents outlining the practical measures of the Green Deal shows that it will decre.....»»
Droughts likely to be even longer in the future due to climate change
