A newly designed electron microscope offers a cost-effective solution for mapping the 3D structures of cellular proteins, providing high-resolution images of biological molecules at a fraction of the cost of traditional models. The cryo-electron microscope allows for efficient analysis of cellular structures, such as the ribosome, and has the potential to revolutionize protein research.
Researchers at Stanford School of Medicine have found a cellular connection between monounsaturated fatty acids, found in the Mediterranean diet, and lifespan in laboratory worms. The study found that oleic acid, a fat in the Mediterranean diet, increases the number of lipid droplets and peroxisomes, two key cellular structures, and protects cellular membranes from damage by oxidation. Worms fed food rich in oleic acid lived about 35% longer than those on standard worm rations. The findings suggest there may be a fat-based strategy to improve human health and longevity.
