Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and partially break apart to bind key DNA sequences that activate division genes. Using cryo-electron microscopy, scientists captured this interaction in remarkable detail. The mechanism appears to be widespread across bacteria, offering a new window into how microbes regulate growth.| More info

Researchers have created a method called optovolution that uses light to guide the evolution of proteins with dynamic behaviors. By engineering yeast cells so their survival depended on proteins switching states at the right time, scientists could rapidly select the best-performing variants. The technique produced new light-sensitive proteins that respond to different colors and improved optogenetic systems. It even evolved a protein that behaves like a tiny logic gate, activating genes only when two signals are present.| More info

A large genetic study shows that many people carry DNA sequences that slowly expand as they get older. Common genetic variants can dramatically alter how fast this expansion happens, sometimes multiplying the pace by four. Researchers also identified specific DNA expansions linked to severe kidney and liver disease. The findings suggest that age-related DNA instability is far more common than previously realized.| More info

A collaboration between Brazilian and German researchers has led to a sunflower-based meat substitute that’s high in protein and minerals. The new ingredient, made from refined sunflower flour, delivers excellent nutritional value and a mild flavor. Tests showed strong texture and healthy fat content, suggesting great potential for use in the growing plant-based food sector.| More info

Researchers at UC San Diego have figured out how to get bacteria to produce xanthommatin, the pigment that lets octopuses and squids camouflage. By linking the pigment’s production to bacterial survival, they created a self-sustaining system that boosts yields dramatically. This biotechnological leap could revolutionize materials science, cosmetics, and sustainable chemistry.| More info
