A high-fat diet can cause the intestinal lining to weaken, allowing live gut bacteria to travel directly to the brain in mice ...

The gut rarely gets the attention the heart or brain receives. Yet it quietly controls digestion, immunity, metabolism, and ...

Humans were not designed for space. Ironically, because we insist on going there anyway, scientists now know from studying astronauts that the lack of Earth’s gravity can wreak health havoc, such as ...

A study in mice concluded that memory problems associated with age may be driven by our gut microbiome and that the vagus ...

Every week, millions of Americans push shopping carts down brightly lit grocery store aisles without realizing they may be ...

Antibiotic resistance is usually treated as a simple yes-or-no problem. A bacterium either survives a drug or it doesn’t. But new research suggests the story may be more complicated. Scientists have ...

The experiment began with a straightforward prediction: microbes from older mice would age young ovaries. But when the ...

For an oyster, creating an internal environment for calcification that forms its distinctive hard shell is essential. But new Harvard research has found that these bivalves may outsource the work, ...

Experiments using mouse models revealed that aging alters the balance of commensal (or helpful) microbes in the gut. These ...

Antibiotic susceptibility in resistant bacteria is not static. New research shows that bacteria harboring resistance genes may respond differently to antibiotics if they are tested under conditions ...
