Researchers trace path of light in photosynthesis

Three billion years ago, light first zipped through chlorophyll within tiny reaction centers, the first step plants and photosynthetic bacteria take to convert light into food.

Shining light to make hydrogen

Decarbonizing the economy and achieving the transition from fossil fuels to renewable energies is one of the most urgent global challenges of the 21st century. Hydrogen can play a key role in this process as a promising climate-neutral ...

Bacteria can tell the time

Humans have them, so do other animals and plants. Now research reveals that bacteria too have internal clocks that align with the 24-hour cycle of life on Earth.

Bioengineered soil microbes may help prevent desertification

By tweaking the genes of microbes in the soil, it may be possible to make arid ecosystems more resilient to climate change and overgrazing, according to a new study. The research is in early stages, and currently consists ...

Spider silk made by photosynthetic bacteria

Spiders produce amazingly strong and lightweight threads called draglines that are made from silk proteins. Although they can be used to manufacture a number of useful materials, getting enough of the protein is difficult ...
