An international team of astrophysicists, astronomers and chemists has found evidence of carbonic acid (HOCOOH) in interstellar space, marking the first time it has been detected in such a setting. In their paper published ...
Plants give us oxygen through photosynthesis—this is commonly taught in school. An international research team has now shown that, particularly in early spring when low temperatures coincide with high light, conifer needles ...
