Japanese collaborators detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu by NASA’s OSIRIS-REx mission.

Lab-based studies reveal how carbon atoms diffuse on the surface of interstellar ice grains to form complex organic compounds, crucial to reveal the chemical complexity in the universe.

A group of researchers from universities in Thailand and Malaysia have collaborated to develop a unique kind of film that is good for the environment and can decompose naturally. They made this film using leftover pineapple stems, which helps reduce the use of harmful plastic films. This new film has the potential to be used as packaging material, contributing to a more sustainable way of doing business and promoting a circular economy.

Muon non-destructive analysis of Asteroid Ryugu revealed the raw materials of solid matter at the outer regions of the early solar system. The samples contain less oxygen relative to silicon than typical CI chondrites, indicating that previous CI chondrite samples may have been contaminated by terrestrial materials, thus redefining the standard elemental composition of solid materials in the solar system.
