Fasting ramps up human metabolism, study shows

Research uncovers previously unknown effects of fasting, including notably increased metabolic activity and possible anti-aging effects. Fasting may help people lose weight, but new research suggests going without food may also boost human metabolic activity, generate antioxidants, and help reverse some effects of aging. Scientists at the Okinawa Institute of Science and Technology Graduate University … More Fasting ramps up human metabolism, study shows

Opposite effect: Protein widely known to fight tumors also boosts cancer growth

Researchers find evidence that genome ‘guardian’ can stimulate cancer Researchers studying p53, the heralded cancer-fighting ‘guardian of the genome,’ found that the human protein also plays a role in promoting tumors, in addition to suppressing them. They found that the PUMA protein works inside the cell’s mitochondria to switch energy production processes and stimulate cancer … More Opposite effect: Protein widely known to fight tumors also boosts cancer growth

Membraneless protocells could provide clues to formation of early life

Membraneless protocells allow RNAs to participate in fundamental chemical reactions, providing clues to early steps in origin of life on Earth. Membraneless assemblies of positively- and negatively-charged molecules can bring together RNA molecules in dense liquid droplets, allowing the RNAs to participate in fundamental chemical reactions. These assemblies, called “complex coacervates,” also enhance the ability … More Membraneless protocells could provide clues to formation of early life
