The effects of the Iran war on the oil market have brought renewed attention to the EU’s plans for domestic production of fossil-free aviation fuels. But EU rules for synthetic aviation fuels risk steering development towards production pathways that are both more expensive and more energy-intensive than necessary – making it harder to meet climate targets. This is shown in a recent study from Chalmers University of Technology, Sweden, that has analysed different methods for producing synthetic methanol.

Stevia is a widely used sweetener, but why do some stevia varieties taste cleaner and more sugar-like than others? Recent research conducted at the University of Toyama shows that stevia’s sweetness is genetically linked to variations in specific glycosyltransferase genes and their cell-specific activity in leaves. By combining genetic analysis with cell-level imaging, the team uncovered how stevia produces its high-value sweet compounds, opening the door to better-tasting natural sweeteners for foods and beverages.

Basilar trunk artery aneurysms are a rare and serious type of brain aneurysm with limited treatment data. A study finds that most patients can be successfully treated using minimally invasive procedures, with nearly nine in ten achieving good recovery. Based on one of the largest single-center analyses to date, this study highlights the effectiveness of modern endovascular techniques while pointing to higher risks in larger aneurysms, emphasizing the need for careful patient selection and follow-up.
