A single act of kindness affects millions

On a single summer day in 1990, Mahmoud Ghannoum’s life changed completely. The research scientist was speaking at a conference in Washington, D.C., while his wife and children continued their family vacation in England. But then, on Aug. 2, Saddam Hussein’s Iraqi forces invaded Kuwait. And Ghannoum, a professor at Kuwait University, suddenly lost hisContinue reading “A single act of kindness affects millions”

Parkinson’s May Begin in Gut and Spread to the Brain Via the Vagus Nerve

The research has presented strong evidence that Parkinson’s disease begins in the gastrointestinal tract and spreads via the vagus nerve to the brain. Many patients have also suffered from gastrointestinal symptoms before the Parkinson’s diagnosis is made. The image is for illustrative purposes only. A major epidemiological registry-based study from Aarhus University and Aarhus UniversityContinue reading “Parkinson’s May Begin in Gut and Spread to the Brain Via the Vagus Nerve”

The Gut of Mice Communicates with the Brain Through the Vagus Nerve, forming a possible basis for a 6th Sense

by SUKANYA CHARUCHANDRA Previous research has shown that the gut-brain connection, which refers to signaling between the digestive and the central nervous systems, is based on the transport of hormones, but a study published today (September 21) in Science suggests there may be a more direct link—the vagus nerve. This research presents “a new setContinue reading “The Gut of Mice Communicates with the Brain Through the Vagus Nerve, forming a possible basis for a 6th Sense”

Gut bacteria’s shocking secret – they produce electricity.

Listeria bacteria transport electrons through their cell wall into the environment as tiny currents, assisted by ubiquitous flavin molecules (yellow dots). (Amy Cao graphic, copyright UC Berkeley) By Robert Sanders While bacteria that produce electricity have been found in exotic environments like mines and the bottoms of lakes, scientists have missed a source closer toContinue reading “Gut bacteria’s shocking secret – they produce electricity.”

Microbes in our guts have been with us for millions of years

By Ann Gibbons Humans did not evolve alone. Tens of trillions of microbes have followed us on our journey from prehistoric ape, evolving with us along the way, according to a new study. But the work also finds that we’ve lost some of the ancient microbes that still inhabit our great ape cousins, which couldContinue reading “Microbes in our guts have been with us for millions of years”

Keeping gut bacteria in balance could help delay age-related diseases

Why do some people remain healthy into their 80s and beyond, while others age faster and suffer serious diseases decades earlier? New research led by UCLA life scientists may produce a new way to answer that question—and an approach that could help delay declines in health. Specifically, the study suggests that analyzing intestinal bacteria couldContinue reading “Keeping gut bacteria in balance could help delay age-related diseases”
