A new machine-learning-based approach to mapping real-time tumor metabolism in brain cancer patients, developed at the ...

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 ...

In a peer-reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor (LUCA) is the single life form that branched into ...

MIT researchers found that a diet rich in the amino acid cysteine may rejuvenate the small intestine by activating immune pathways that boost stem cell regeneration. The discovery could pave the way ...

It’s hard to imagine many kitchens without soy sauce. Thanks to its deep umami flavor, easy accessibility and salty kick, we splash it on stir-fries, marinate meats with it, drizzle it over rice and ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

Amino acids are absolutely essential to our health—and for life itself. They are the so-called “building blocks” of proteins. They play a key role in the growth, repair, and maintenance of almost ...

In short, AHAs work by exfoliating, and that process makes skin look instantly more refreshed. Though a scrub can also remove dead cells, chemically exfoliating with alpha hydroxy acid products can go ...

It may conjure images of Family Matters' bespectacled, suspenders-clad Steve Urkel. Or the theoretical physicist Sheldon Cooper from The Big Bang Theory. Or Scooby-Doo's Velma. Or you may ...

The tumor microenvironment is not just a site of cancer growth—it is a high-stakes metabolic contest where tumor and immune cells vie for limited resources. Amino acids, once seen as passive nutrients ...

Amino acid metabolism in the TIME. The TIME is shaped by metabolic competition between tumor and immune cells. Amino acids have key roles in modulating immune responses and tumor progression. (A) ...
