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 ...

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

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 ...

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 ...

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 ...

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 ...

Before optogenetics emerged, researchers studying neural signaling relied largely on voltage- and calcium-sensitive dyes, as well as probes designed to detect changes in pH. Combined with the use of ...
