_E. coli_ is one of the most widely studied organisms – and that may be a problem for both science and medicine

Researchers uncovered the foundations of biology by using E. coli as a model organism. But over-reliance on this microbe can lead to knowledge blind spots with implications for antibiotic resistance.

Microbes in your food can help or hinder your body's defenses against cancer – how diet influences the conflict between cell 'cooperators' and 'cheaters'

Cancer cells are ‘cheaters’ that do not cooperate with the rest of the body. Certain microbes in your diet can either protect against or promote tumor formation by influencing cell cooperation.

Humans evolved with their microbiomes – like genes, your gut microbes pass from one generation to the next

As early modern humans spread across the globe, their gut microbes genetically changed with them. Understanding the origins of gut microbes could improve understanding of their role in human health.

Gut microbes help hibernating ground squirrels emerge strong and healthy in spring

Months not eating or moving don’t result in muscle wasting and loss of function for animals that hibernate. New research found gut microbes help their hosts hold onto and use nitrogen to build proteins.

Feeding cows a few ounces of seaweed daily could sharply reduce their contribution to climate change

Cow burps and farts are no joke – they're a big factor in climate change. A new study shows that daily seaweed supplements could tame this major methane source while saving ranchers money.
