Life may have emerged from a surprisingly simple network of chemical reactions long before cells or genes existed.

“Other signs of prolonged insufficient protein intake include leg swelling, anemia, and poor wound healing,” Jones adds. While severe edema from protein deficiency is rare in developed countries, mild ...

Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the molecular "protein factories" of our bodies. The ...

Metabolic reprogramming in the tumor microenvironment shapes immune function and therapy resistance, offering insights into ...

Pyruvate dictates redox balance and cell size, establishing metabolism as a dominant regulator of cellular fitness, unveiling new strategies to modulate cancer, regeneration, and diabetes.

The authors provide a useful integrated analytical approach to investigating MASLD focused on diverse multiomic integration methods. The strength of evidence for this new resource is solid, as ...

Siddhartha Mukherjee, oncologist and author of “The Emperor of All Maladies,” asks: What if we change what a tumor can eat?

Scientists identified cellular metabolism and energy signaling as a central factor connecting genetic and environmental ...

Metabolic dysfunction-associated steatotic liver disease (MASLD), a spectrum of liver conditions ranging from simple ...

One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of ...

Tryptophan, the essential amino acid behind the Thanksgiving myth that eating turkey can make you sleepy, has been found to exist on Bennu, a small asteroid that swings by our planet about every six ...
