Food safety: Dung beetles and soil bacteria reduce risk of human pathogens

5 days ago from Physorg

Food safety regulations increasingly pressure growers to remove hedgerows, ponds and other natural habitats from farms to keep out pathogen-carrying wildlife and livestock. Yet, this could come at the cost...

Superbugs have colonized the International Space Station—but there's a silver lining

5 days ago from Physorg

Astronauts leave behind many things when they boldly go. Bacteria, however, stay with them.

Algal library lends insights into genes for photosynthesis

5 days ago from Science Daily

To identify genes involved in photosynthesis, researchers built a library containing thousands of single-celled algae, each with a different gene mutation. The library, which took nine years to construct, has...
