China approves 1st new drug for Alzheimer’s disease in 17 years

By Julie Zaugg and Jared Peng Authorities in China have approved a drug for the treatment of Alzheimer’s disease, the first new medicine with the potential to treat the cognitive disorder in 17 years. The seaweed-based drug, called Oligomannate, can be used for the treatment of mild to moderate Alzheimer’s, according to a statement fromContinue reading “China approves 1st new drug for Alzheimer’s disease in 17 years”

How a Man’s Fecal Transplant Turned Fatal

An infection with a drug-resistant strain of E. coli proved fatal for a man who received a fecal transplant. The first person known to die as a result of a fecal transplant is a 73-year-old man who developed a fatal infection with antibiotic-resistant bacteria that were in the donor’s stool sample. News of the man’sContinue reading “How a Man’s Fecal Transplant Turned Fatal”

Gut microbes can impact the efficacy of Parkinson’s disease medications

by DAVID NIELD Dosing medicines can be a tricky process: How much of a medication actually ends up hitting its target can vary a lot between patients, sometimes for mysterious reasons. As it turns out, even the things living in our bodies could be gobbling up our drugs. In a series of experiments with levodopaContinue reading “Gut microbes can impact the efficacy of Parkinson’s disease medications”

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”

Fecal Transplant Therapy in Kids Has Reduced Their Autism Severity by 47%

by MIKE MCRAE Transforming the microbial environment in the guts of children diagnosed with autism could significantly ease the severity of their condition’s signature traits, according to newly published research. A study on the effects of a form of faecal transplant therapy in children on the autism spectrum found participants not only experienced fewer gutContinue reading “Fecal Transplant Therapy in Kids Has Reduced Their Autism Severity by 47%”

Germs in Your Gut Are Talking to Your Brain. Scientists Want to Know What They’re Saying.

By Carl Zimmer In 2014 John Cryan, a professor at University College Cork in Ireland, attended a meeting in California about Alzheimer’s disease. He wasn’t an expert on dementia. Instead, he studied the microbiome, the trillions of microbes inside the healthy human body. Dr. Cryan and other scientists were beginning to find hints that theseContinue reading “Germs in Your Gut Are Talking to Your Brain. Scientists Want to Know What They’re Saying.”

Herbicide may harm the microbiome of bees and make them more susceptible in infections.

by IRIS KULBATSKI Consuming a mixture of sugar syrup and glyphosate, the active ingredient in Monsanto’s Roundup herbicide, alters honey bees’ microbiomes, and these changes increased mortality among insects exposed to pathogenic bacteria, according to a study published yesterday (September 24) in PNAS. Glyphosate is the most commonly used herbicide worldwide. It acts by blockingContinue reading “Herbicide may harm the microbiome of bees and make them more susceptible in infections.”

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”

Young children’s oral bacteria may predict obesity

Weight gain trajectories in early childhood are related to the composition of oral bacteria of two-year-old children, suggesting that this understudied aspect of a child’s microbiota — the collection of microorganisms, including beneficial bacteria, residing in the mouth — could serve as an early indicator for childhood obesity. A study describing the results appears SeptemberContinue reading “Young children’s oral bacteria may predict obesity”

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.”
