Light-absorbing carbonaceous aerosols (LACs), including black carbon (BC) and brown carbon (BrC), are among the most significant radiatively-active components in the Earth system. LACs play crucial ...

Researchers have engineered one of the world's first yeast cells able to harness energy from light, expanding our understanding of the evolution of this trait -- and paving the way for advancements in ...

Evolution is biology's powerful method of engineering. It works by generating many variants of DNA, RNA, and proteins inside cells and letting nature "select" the organism that performs best. Early ...

A universe with half-speed light might never produce New Scientist readers capable of posing this question, notes one reader ...

Scientists have unraveled the evolutionary journey of a unique type of photosynthesis that allows some bacteria to harness far-red light, a region beyond the visible spectrum. This discovery could ...

A new study provides the first insights into how thylakoid membranes—the internal compartments where oxygen-producing photosynthesis takes place—emerged during evolution. By comparing the genomes of ...

Bioluminescence, the ability of living organisms to emit light, is a fascinating phenomenon observed in various life forms, including deep-sea fish, glowing mushrooms, and fireflies. Fireflies have ...

Approximately 50 µg of each oil sample was sealed in a tin capsule and loaded into the autosampler carousel of a Thermo Finnigan Delta XL isotope ratio mass spectrometer. The oxidation and reduction ...
