NewsResearch reveals that probiotics slow spread of deadly disease decimating Caribbean reefs
Scientists with the Smithsonian’s National Museum of Natural History have discovered that a bacterial probiotic helps slow the spread of stony coral tissue loss disease (SCTLD) in already infected wild corals in Florida. The findings, published today in the journal Frontiers in Marine Science, reveal that applying the probiotic treatment ...

NewsBacteria hitch a ride on yeast puddles to zoom around
Researchers found that bacteria can speed up by using the fluid pockets shaped by neighboring yeast cells. These microscopic moisture trails allow bacteria to swim farther and spread faster—revealing a new way for microbes to travel through soil, plants, and the human body.

NewsStudy resolves diatom tree of life - and could offer clues to Earth’s puzzle
A new study finds that diatoms evolved slowly for the first 100 million years of their existence. Then, 170 million years ago, they reached an inflection point characterized by a burst of rapid speciation orders of magnitude faster than anything that had preceded it.
