Recreating the natural light-harvesting nanorings in photosynthetic bacteria

Photosynthesis in plants and some bacteria relies on light-harvesting (LH) supramolecules, which come in different structures. So far, these LH molecules have not been artificially prepared. In a recent study, scientists managed to synthesize LH nanorings via self-assembly of chlorophyll derivatives and examined the external conditions that drove their...

New insights on why improvements to Chesapeake Bay remain a challenge

A new look at the history of water quality in the Chesapeake Bay sheds light on how the estuary has responded to nutrient reduction efforts and why improvements have remained a major challenge. Environmental science researchers looked at the Bay's historic response to efforts to reduce nutrients to minimize dead zones -- areas with too little oxygen...
