So Your Kitchen Sponge Is A Bacteria Hotbed. Here's What To Do : The Salt : NPR
Anyone who has worked with food-borne pathogens — or their close relatives — knows that these little critters aren't "the strongest." They are weaklings. You heat them up just a little bit and they literally pop!

"That's why we cook food. We know that heating will kill the pathogens," says Jennifer Quinlan, a food microbiologist at Drexel University.

So what in the heck is going on with this new sponge study? Are the findings upturning decades of public health recommendations?

Not at all, Quinlan says. The media reports were simply not accurate.

"After you contacted me for an interview, I read the study in great detail," she says. "I feel now that the comments they make about not recommending washing in the abstract are really, really misleading."

In fact, she says, you can't draw any conclusions about the effect of washing sponges from this study.

For starters, there was no clear explanation of what "regular cleaning" meant, she says.

The zoo beneath our feet: We’re only beginning to understand soil’s hidden world - The Washington Post
Plants manufacture carbohydrates through photosynthesis, but not just for themselves. They release some of their carbon sugars into the soil, which causes the bacteria and fungi to show up to feed. The bacteria crowd around the root zone, and the fungi form vast networks of interlocking strands that often link one plant to another. The bacteria convert nitrogen and other nutrients into forms the plants can use, often by getting devoured by other microbes.

Bacterial in-fighting provides new treatment for hospital infections - Latest - News - The University of Sheffield
The research has so far only been carried out in the laboratory and in animal studies, so further work will be needed before the treatment can be made available in the clinic.
