Analysis of organic compounds -- called polycyclic aromatic hydrocarbons (PAHs) -- extracted from the Ryugu asteroid and Murchison meteorite has found that certain PAHs likely formed in the cold areas ...

Chemical reactions occur when elements or compounds combine and create new compounds. Elements are substances that contain only one type of atom and are represented by unique symbols on the periodic ...

Carbon is often referred to as "the bedrock of life" because the element appears in all known life forms. This is because the sixth entry on the periodic table has the unique ability to form the ...

Deep within giant planets, helium may form stable compounds with other elements, a new study finds — something that was long thought never to happen in nature. Helium is second only to hydrogen as the ...

Helium, the gas that fills up our balloons, has a reputation as a chemistry lightweight—as an element that doesn’t react with much of anything. Researchers say they’ve used high pressure to coax ...

(Beyond Pesticides, November 20, 2025) Recent scientific literature finds heightened toxicity associated with pesticide metabolites, the transformation/breakdown products of the parent compounds, that ...

Chemists studying how life started often focus on how modern biopolymers like peptides and nucleic acids contributed, but modern biopolymers don't form easily without help from living organisms. A ...
