There are "costs of life" that mechanical physics cannot calculate. A clear example is the energy required to keep specific biochemical processes active—such as those that make up photosynthesis, ...

Researchers at University of California, Los Angeles (UCLA) have developed a tiny sensor that can help keep tabs on metabolites – substances produced or used when your body breaks down food, ...

The intestine is home to a complex ecosystem of microorganisms. This so-called gut microbiome plays an important role in health, disease, and aging. Various studies suggest that the microbiome "ages" ...

Despite their fundamental differences, plants, animals, and fungi share certain metabolic processes. Biologists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have discovered ...

Aging is a complex process that has long puzzled scientists. A recent study published in Engineering proposes a new theory called Pro-Aging Metabolic Reprogramming (PAMRP), which could change our ...

The amino acid glutamine plays an unexpected role in erythropoiesis, the differentiation of erythroid progenitor cells into mature red blood cells. Ordinarily, glutamine is broken down by stem cells ...
