UK researchers “hack” earliest stages of photosynthesis

In the UK, researchers have ‘hacked’ the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to new ways of generating clean fuel and renewable energy.

An international team of physicists, chemists and biologists, led by the University of Cambridge, was able to study photosynthesis – the process by which plants, algae and some bacteria convert sunlight into energy – in live cells at an ultrafast timescale: a millionth of a millionth of a second.

Despite the fact that it is one of the most well-known and well-studied processes on Earth, the researchers found that photosynthesis still has secrets to tell. Using ultrafast spectroscopic techniques to study the movement of energy, the researchers found the chemicals that can extract electrons from the molecular structures responsible for photosynthesis do so at the initial stages, rather than much later, as was previously thought.
