Figuring out how immune cells prevent cognitive decline

Could Alzheimer’s disease and other types of cognitive decline be caused by the underproduction of immune cells that are poorly understood? It might, according to a Rutgers study published in Nature Immunology, and increasing these cells could undo the harm.

Acute infection disrupts the healthy balance between the good and bad gut microbes

Rutgers researchers examined the impact of COVID-19 on patients’ microbiomes, the group of microbes that live in and on the human body.

Exploring behavioral variation in a non-captive animal population

For the first time, researchers demonstrate that monkeys with a more social nature—those that groom or are groomed more frequently and with more grooming partners—have a better gut microbiome.

More sociable monkeys have higher abundance of friendly gut microbes

More sociable monkeys have a higher abundance of certain beneficial gut bacteria, and a lower abundance of potentially disease-causing bacteria, new research has found.

UO research in zebrafish shows a gut-brain link that influences social behavior

To learn to socialize, zebrafish need to trust their gut. Gut microbes encourage specialized cells to prune back extra connections in brain circuits that control social behavior, new UO research in zebrafish shows.

Short-term tomato consumption alters gut bacteria toward a more favorable profile

Two weeks of eating a diet heavy in tomatoes increased the diversity of gut microbes and altered gut bacteria toward a more favorable profile in young pigs, researchers found.

“Screen-first” approach mines microbes directly from the environment

The best method now available for researchers to isolate a specific microorganism with a given metabolic function from an environment is to collect a sample of cells, culture them, and then test them for the desired cell functions.

New method reveals how photosynthetic microalgae interact with their environment

Microalgae are algae too small to see with the human eye that live in both fresh and sea water. They are responsible for half of fixation of carbon that occurs on Earth through photosynthesis.

Bacteria do engage in photosynthesis, research suggests

Knowing whether or not marine microbes engage in photosynthesis -; the use of sunlight to turn carbon dioxide and water into energy -; could help scientists to learn if ocean bacteria play a role in the global carbon cycle.

Saving ocean habitats with newer genomic technologies

In an essay published on October 17th, 2022 in the open-access journal PLOS Biology, Madeleine van Oppen of the Australian Institute of Marine Science and the University of Melbourne and Melinda Coleman of the New South Wales Department of Primary Industries argue that genetic and genomic technologies have tremendous potential for protecting marine life but are currently underutilized.

Dual threat may lead cyanobacteria to take in more carbon

The types of ocean bacteria known to absorb carbon dioxide from the air require more energy – in the form of carbon – and other resources when they're simultaneously infected by viruses and face attack from nearby predators, new research has found.

Bacterial warfare in the gut can have collateral beneficial effects

Nearly ten years ago, a graduate student at UO Jennifer Hampton Hill stumbled upon something fortunate: a peptide produced by gut bacteria that prompted the division of cells that make insulin.

Gut microbiome’s influence on how lifestyle affects dementia risk

A recent Baycrest study points to the possibility that the gut microbiome influences how nutrition and exercise impact brain health and dementia risk. Physicians and researchers could be able to improve dementia prevention efforts with the use of this knowledge.

New technique identifies tumor-associated microbes

Researchers from Rutgers Cancer Institute of New Jersey and RWJBarnabas Health investigated the microbiome of pancreatic tumors and discovered certain microbes linked to inflammation and poor survival.

Spores integrate environmental signals over time

When exposed to starvation and stress, certain bacteria enter a dormant state in which life functions cease. These cells, known as spores, can resist punishing extremes of heat, pressure, and even the extreme conditions of outer space by entering a profound hibernation.

Microbiome manipulation to prevent and cure diseases

Tagbo Niepa, assistant professor of chemical engineering at the University of Pittsburgh, is inspired by this possibility in his research. His work on using the microbiome to enhance human health was recognized with a $2 million New Innovator Award from the National Institutes of Health, which funds “exceptionally creative scientists proposing high-risk, high-impact research.”
