Des scientifiques découvrent un motif de Voronoï dans les feuilles de la plante à monnaie chinoise

Des chercheurs ont identifié un motif géométrique naturel, connu sous le nom de diagramme de Voronoï, dans les feuilles de la plante à monnaie chinoise. Cette découverte révèle comment la plante organise ses pores et ses nervures en utilisant des principes courants en urbanisme et en conception de réseaux.

Une équipe du Cold Spring Harbor Laboratory a cartographié les minuscules pores et les nervures en boucle des feuilles de Pilea peperomioides. Ils ont découvert que ces structures divisent naturellement l'espace autour de points centraux de la même manière que les diagrammes de Voronoï en mathématiques et en informatique. Le professeur associé Saket Navlakha a dirigé ces travaux avec l'ancienne étudiante diplômée Cici Zheng et le collaborateur Przemysław Prusinkiewicz.

Scientists at EPFL report that a transient shape change in mitochondria—known as “pearling,” in which the organelle briefly forms bead-like constrictions—can redistribute clusters of mitochondrial DNA (mtDNA) into more evenly spaced nucleoids. The work, published April 2, 2026 in Science, suggests the process is triggered by calcium influx into mitochondria and may help explain how cells maintain robust mtDNA organization, a feature implicated in a range of mitochondrial-related disorders.

Researchers have created a molecule with a novel topology resembling a half-Möbius strip, requiring four loops to return to the starting point. The structure, made from 13 carbon atoms and two chlorine atoms, was assembled on a gold surface at low temperatures. This discovery highlights potential advances in molecular engineering and quantum simulations.

An international team including researchers from Cornell University, the Boyce Thompson Institute, the University of Edinburgh, and others has uncovered how hornwort plants use a modified protein, RbcS-STAR, to cluster the key photosynthetic enzyme Rubisco into pyrenoid-like compartments. This mechanism boosts carbon capture and could enhance crop yields by up to 60 percent while reducing needs for water and fertilizers.
