Gut Bacteria

Investigating ways to head off the chain of events that leads to multiple sclerosis, researchers have found a chemical regulator in mice that causes the inflammatory cascade associated with the disease. They also figured out how to switch it off.

E. coli is arguably the most well-studied organism on Earth, but scientists have now discovered a new behavior that’s almost never seen in bacteria. The normally single-celled organisms have shown signs of previously unknown multicellular phases.
-
Over the past 150 years, researchers have seen the average human body temperature drop by more than half a degree Fahrenheit (0.3 °C). Now, researchers are speculating microbiome changes could be driving these long-term body temperature variations.
-
In a first-of-its-kind study, researchers have trekked to remote Tibetan Buddhist temples to study the gut microbiomes of meditating monks. The findings suggest the long-term practice of deep meditation could positively impact gut bacteria composition.
-
Staphylococcus aureus is a common bacterium in humans, but it can turn nasty. A new clinical trial has shown that a probiotic can selectively cut populations of the bug in humans, reducing the risk of infection without the hazards of antibiotics.
-
A fascinating study has shed light on how the trillions of microbes in our gut could be affecting our brain health. The research found mice engineered to develop Alzheimer's developed fewer signs of neurodegeneration when raised with no gut bacteria.
-
Researchers have demonstrated a form of fermentable fiber can lower blood pressure in patients with hypertension. The placebo-controlled trial revealed just three weeks of supplementation decreased blood pressure as effectively as currently used drugs.
-
An ongoing study is investigating the relationship between our gut microbiome and the development of type 2 diabetes. Early data from the study indicates bacteria producing a specific fatty acid can be linked to healthier blood sugar levels.
-
A team of researchers has looked to the microbiome to understand what role gut bacteria may play in weight gain. The findings suggest some bacteria may be more efficient at extracting energy from food, and this could lead to weight gain.
-
In the commercial production of apple juice and cider, large quantities of fibrous waste – known as pomace – is generated as a byproduct. And while that material is currently just discarded, new research suggests that it could be used to boost the health of chickens.
-
A compelling new study has identified a gut-brain pathway in mice that connects specific gut bacteria with motivation for exercise. If the same pathway is confirmed in humans it could mean modifying one's microbiome may help prompt a desire for exercise.
-
Two new studies offer some of the strongest evidence to date for a relationship between depression and gut bacteria. The studies do not claim causality but do suggest a strong correlation that could inform novel diagnostic biomarkers for depression.
