Researchers found that sterilized soil continues to consume oxygen and release carbon dioxide for years, suggesting metabolic-like reactions can occur outside living cells. The finding, published in Science Advances, may imply that some biochemical processes predate life on Earth.
New research published in Nature reveals that bird retinas survive without oxygen by using anaerobic glycolysis, solving a long-standing paradox of how one of the most metabolically active tissues functions without blood perfusion.
The article explains the biochemical mechanism of GLP-1 agonists, including the new drug retatrutide, and how they regulate appetite and energy metabolism by mimicking natural hormones.
