Scientists Develop

• Des chercheurs du MIT ont découvert que la lumière laser chaotique peut s'auto-organiser en un « faisceau crayon » hautement focalisé sous des conditions précises, permettant une imagerie 3D rapide de la barrière hémato-encéphalique. • La nouvelle méthode permet une imagerie 25 fois plus rapide que les techniques actuelles et suit en temps réel le mouvement des médicaments dans les cellules cérébrales. • Cette percée pourrait accélérer les traitements des maladies neurologiques en permettant l'observation de haute précision de l'absorption des protéines dans les cellules.

Oxford team’s technology picked up danger signs with 86% accuracy in study of 72,000 patients in EnglandOxford scientists have developed a simple AI tool that can predict the risk of heart failure five years before it develops.More than 60 million people worldwide have the condition in which the heart cannot pump blood around the body as well as it should. Spotting cases before they develop into heart failure would be a big step forward, experts say. Doctors could prepare better for and manage the condition at an earlier stage or even prevent it entirely. Continue reading...

Bread and biscuits made from Crispr-edited wheat showed substantially reduced acrylamide levels, even after toastingGene-edited wheat which can make bread less carcinogenic when toasted has been successfully developed by scientists.Researchers at Rothamsted Research in Harpenden, Hertfordshire, used Crispr genome editing which allows researchers to selectively edit the DNA of living organisms. This revolutionary technology was adapted for use in the laboratory from naturally occurring genome editing systems found in bacteria. Continue reading...
