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 ...

Remember that the lattice arrangement is giant - for example, a single grain of salt may contain 1.2 × 10 18 (1,200,000,000,000,000,000) ions. The lattice arrangement continues in three dimensions.

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 ...

Three studies find that a family of organic compounds affects the formation and initial growth of atmospheric aerosol particles in clean air — with implications for our knowledge of the climate ...

Helsinki/Jülich/Leipzig. Scientists made an important step in order to better understand the relationships between vegetation and climate. So-called extremely low-volatility organic compounds, which ...
