Beige fat cells with a “Sisyphus mechanism”

Researchers have discovered a new type of beige fat cells that consume energy and produce heat through a futile-cycle mechanism, known as the 'Sisyphus mechanism'. These cells are found in adults and help break down excess fat, leading to improved metabolic health and reduced risk of obesity.

How mitochondria get their membranes bent

A research team at Goethe University Frankfurt has identified two proteins, Fcj1 and Su e/g, that regulate the shape of mitochondria's inner membrane. The protein Fcj1 promotes negative curvature, while the Su e/g protein induces positive bending, leading to the formation of cristae junctions.
