Plants are green because of a pigment that is key to photosynthesis: chlorophyll. In its production, the enzyme chlorophyll synthase plays an important role. As part of an international collaboration, researchers from Osnabrück University, the Center Algatech in Třeboň and the University of Sheffield have now succeeded in deciphering the structure of this enzyme and gaining valuable insights into its mechanism.
The findings are published in the journal Nature Chemical Biology.

Centaurus A in the spotlight: Plasma simulations reproduce black hole jets' mysterious bright edges
Around 12 million light-years away, the supermassive black hole of the galaxy Centaurus A is hurling two enormous plasma jets into space at nearly the speed of light. These so-called jets are brighter at their edges than at their center. The reason for this was previously unclear

New review explores how faint 'glow' from plants could transform global monitoring of photosynthesis
A faint glow emitted by plants as they absorb sunlight could offer scientists a powerful new way to monitor photosynthesis across the planet. Fully realizing that potential, however, will require advances in both the general understanding of plant biology and the satellite techno

A radical theory says the universe is twice as old as we thought
A provocative new cosmological model suggests the Universe could be 26.7 billion years old and might not need dark matter or dark energy to explain its behavior. University of Ottawa researchers tested the theory against several major astronomical observations, finding that it co

Comets may have destroyed life's ingredients instead of delivering them to Earth
A century-old theory about the origins of life on Earth may be wrong. New research from the University of Cambridge suggests that comets traveled too fast and struck at unfavorable angles for the fragile molecules needed for life to survive, making successful delivery extraordina
