Mining rare earth metals from electronic waste      (via sciencedaily.com)     Original source 

A small molecule that naturally serves as a binding site for metals in enzymes also proves useful for separating certain rare earth metals from each other. In a proof of concept, the process extracts europium directly from fluorescent powder in used energy-saving lamps in much higher quantities than existing methods. The researchers are now working on expanding their approach to other rare earth metals. They are in the process of founding a start-up to put the recycling of these raw materials into practice.

Companies that mitigate climate change reduce their cost of capital      (via sciencedaily.com)     Original source 

A recent study explored the relationship between corporate climate change mitigation actions and the cost of capital for 2,100 Japanese listed companies from 2017 to 2021. The findings reveal that companies that maintain lower carbon intensity and disclose more climate-related information can reduce their capital costs. Conversely, mere commitments to climate change without actionable measures do not significantly impact costs.

Visualizing short-lived intermediate compounds produced during chemical reactions      (via sciencedaily.com)     Original source 

Immobilizing small synthetic molecules inside protein crystals proves to be a promising avenue for studying intermediate compounds formed during chemical reactions, scientists report. By integrating this method with time-resolved serial femtosecond crystallography, they successfully visualized reaction dynamics and rapid structural changes occurring within reaction centers immobilized inside protein crystals. This innovative strategy holds significant potential for the intelligent design of drugs, catalysts, and functional materials.

Exploring the radiative effects of precipitation on Arctic amplification and energy budget      (via sciencedaily.com)     Original source 

While, in theory, precipitation impacts the Earth's radiation budget, the radiative effects of precipitation (REP) are poorly understood and excluded from most climate models. Hence, a new study examined the role of REP in the global and regional energy budgets and hydrological cycles, finding that REP significantly contributes to temperature and precipitation variations at different geographical scales, especially in the Arctic warming. This highlights the relevance of including REP in climate modeling for improved accuracy.

The dawn of the Antarctic ice sheets      (via sciencedaily.com)     Original source 

In recent years global warming has left its mark on the Antarctic ice sheets. The 'eternal' ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its formation, as an international research team has now discovered: sediment samples from drill cores combined with complex climate and ice-sheet modelling show that permanent glaciation of Antarctica began around 34 million years ago -- but did not encompass the entire continent as previously assumed, but rather was confined to the eastern region of the continent (East Antarctica).
