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 ...

Bio-inspired nano-catalyst guides chiral reactions

Many medicines are twisted molecules with two mirror image versions, but the body uses only one. Inspired by photosynthetic bacteria, a team at the University of Michigan built a catalyst that guides chemical reactions toward ...

What delayed Earth's oxygenation?

Powering a massive biosphere on Earth, photosynthesis is the light-mediated reaction that converts carbon dioxide and water to carbohydrates and oxygen. About 2.3 billion years ago, this reaction led to a dramatic oxygenation ...
