What would be the most effective use of a certain plot of land in terms of the climate crisis: planting a forest, which is a natural means of absorbing carbon dioxide from the atmosphere, or erecting fields of solar panels, which reduce the emission of carbon dioxide into the atmosphere? This dilemma has long been debated by decision-makers around the world. Now, for the first time -- based on findings from arid areas and on comprehensive measurements of the energy flow exchanged between the ground and the atmosphere -- we may have an answer to this question.

Antibodies hold promise as therapeutic agents. However, their tendency to aggregate poses significant challenges to drug development. In a groundbreaking study, researchers now provide novel insights into the structure formed due to 3D domain swapping of the antibody light chain, the part of the antibody contributing to antigen binding. Their findings are expected to lead to improvements in antibody quality and the development of novel drugs.

Chemists have now come up with a way to make molecules known as acenes more stable, allowing them to synthesize acenes of varying lengths. Using their new approach, they were able to build molecules that emit red, orange, yellow, green, or blue light, which could make acenes easier to deploy in a variety of applications.

Scientists have made a significant stride toward understanding a viable process for direct air capture, or DAC, of carbon dioxide from the atmosphere. This DAC process is in early development with the aim of achieving negative emissions, where the amount of carbon dioxide removed from the envelope of gases surrounding Earth exceeds the amount emitted.

Enzymes from microorganisms can produce hydrogen (H2) under certain conditions, which makes them potential biocatalysts for biobased H2 technologies. In order to make this hydrogen production efficient, researchers are trying to identify and eliminate possible limiting factors. These include formaldehyde, which occurs naturally as a metabolic product in cells and inhibits the particularly efficient [FeFe] hydrogenase.

Used lithium-ion batteries from cell phones, laptops and a growing number of electric vehicles are piling up, but options for recycling them remain limited mostly to burning or chemically dissolving shredded batteries. Researchers have improved on approaches that dissolve the battery in a liquid solution in order to reduce the amount of hazardous chemicals used in the process. This simple, efficient and environmentally-friendly solution overcomes the main obstacles presented by previous approaches.
