Water is essential for life as we know it, but it has paradoxically been considered inimical to
the emergence of life. Proteins and nucleic acids have sustained evolution and life for …

Samples of the carbonaceous asteroid (162173) Ryugu were collected and brought to Earth
by the Hayabusa2 spacecraft. We investigated the macromolecular organic matter in Ryugu …

Numerous data analysis methodologies depend on the Fourier transform (FT), especially in
analytical chemistry. The FT is a potent and versatile tool, influencing many scientific …

The pristine sample from the near-Earth carbonaceous asteroid (162173) Ryugu collected
by the Hayabusa2 spacecraft enabled us to analyze the pristine extraterrestrial material …

Forty years ago, it was proposed that gas-phase organic chemistry in the interstellar medium
can be initiated by the methyl cation CH3+ (refs.,–), but so far it has not been observed …

The near-Earth carbonaceous asteroid (162173) Ryugu is expected to contain volatile
chemical species that could provide information on the origin of Earth's volatiles. Samples of …

Abstract On September 24, 2023, NASA's OSIRIS‐REx mission dropped a capsule to Earth
containing~ 120 g of pristine carbonaceous regolith from Bennu. We describe the delivery …

Samples from the carbonaceous asteroid (162173) Ryugu provide information on the
chemical evolution of organic molecules in the early solar system. Here we show the …

Managing and increasing organic matter in soil requires greater understanding of the
mechanisms driving its persistence through resistance to microbial decomposition …

Polycyclic aromatic hydrocarbons (PAHs) are organic molecules containing adjacent
aromatic rings. Infrared emission bands show that PAHs are abundant in space, but only a …
