Cyanobacteria: appearance, adaptation and reproduction

May 19, 2018

The cyanobacteria appeared early in the history of the Earth, while conditions were not favorable to the life forms we know today. How did they live in these inhospitable times? How have they evolved and survived until today Where do the algae come from?  Diagram of a cyanobacteria in section. © DR There are between 1,500 and 2,500 species of cyanobacteria, they are […]

A promising artificial photosynthesis inspired by… a frog

May 19, 2018

American engineers want to mimic plants and even do better than them by performing a very effective artificial photosynthesis, able to use solar energy to produce biofuels or capture carbon. Their secret? A curious foam inspired by a frog, in which photosynthesis is achieved by freeing itself from certain constraints of plants. The unexpected combination of a […]

A biofuel directly produced by photosynthesis

May 19, 2018

By cleverly modifying the workings of photosynthesis by bacteria, researchers have managed to make them make hydrogen gas. What transform these microorganisms into plants to make biofuel used in fuel cells. Operating diagram of a fuel cell. The molecular hydrogen produced during photosynthesis could be used as the main fuel. A fuel cell provides current from hydrogen and […]

A microbial plant cell for the electricity of tomorrow?

May 19, 2018

Live plants could be used for bioelectricity production! A prototype microbial cell has just been made, fed with glucose from the photosynthesis of a plant. The marshes or the rice fields of the globe could in this way become power plants, as well as our roofs! Marjolein Helder  from the University of Wageningen (The Netherlands) and David Strik […]
