A Carnegie-based search of nearby galaxies for their oldest stars has uncovered two stars in the Sculptor dwarf galaxy that were born shortly after the galaxy formed, approximately 13 billion years ...

Recent studies have revealed that cancers leave distinct chemical signatures in the body, which can be detected early on. These “chemical fingerprints” offer promising avenues for early diagnosis and ...

The NIST Mass Spectral Library has expanded to include new human and plant metabolites, variants of fentanyl and other synthetic drugs. The National Institute of Standards and Technology (NIST) has ...

Medicines have a unique chemical fingerprint, according to a new study from the University of Copenhagen. Researchers say this knowledge can be used to trace counterfeit or stolen medicine. Subscribe ...

New technology is tracking the origins of seafood in a bid to combat fraudulent labeling and improve sustainability. Chemical fingerprints found in the bones and shells of marine life is key to ...

Scientists developed a new microfluidic system that can detect subtle chemical fingerprints from bacteria - helping identify even antibiotic-resistant strains. This technology could help physicians ...

13.1 billion years ago, one of the universe’s first stars exploded. When a massive star dies, the supernova typically blows the outer layers of the star into space, leaving the star’s collapsed core ...

(Nanowerk News) Flip through any chemistry textbook and you’ll see drawings of the chemical structure of molecules—where individual atoms are arranged in space and how they’re chemically bonded to ...

NIST research chemist Kelly Telu injects a sample into a mass spectrometer, a laboratory instrument that scientists use to identify unknown chemical compounds. (M. Delorme/NIST) The National Institute ...
