Almost half of the U.S. adult population has high blood pressure — or hypertension — and about 20% of these patients have treatment-resistant hypertension. The reason why some people are resistant to treatment has been a mystery, but new study results show that a certain gut bacterium may be an important factor.

An article says that microplastics have been found in human blood for the first time. We rate this claim as true, although more studies are needed to determine if these substances in humans are associated with a public health risk.
Embargoed press materials are now available for the Experimental Biology (EB) 2022 meeting, featuring cutting-edge research from across the life sciences. EB 2022, to be held April 2–5 in Philadelphia, is the annual meeting of five scientific societies bringing together thousands of scientists and 25 guest societies in one interdisciplinary community.
Reporters are invited to join a live discussion of research announcements at the forefront of the life sciences during a virtual press conference for the Experimental Biology (EB) 2022 meeting. The press conference will be held online from 11–11:45 a.m. Eastern on Friday, April 1, 2022 (RSVP by Thursday, March 31).
A new study led by researchers at University of Utah Health details a novel mechanism that infectious bacteria use to quickly adjust to environmental stress. The discovery could help explain why certain types of common infections—such as urinary tract and bloodstream infections like sepsis—are hard to get rid of.
The lower airways of patients with cystic fibrosis (CF) have unique biochemical features that correlate with the complex communities of lung bacteria typical of this disease, according to a multicenter study led by researchers from Ann & Robert H. Lurie Children’s Hospital of Chicago. These findings offer insights into the underlying biological mechanisms driving infection and inflammation in the CF lungs, and may help develop novel targeted therapies and more precise diagnostics to improve the care of children with CF.
All of the medicines derived from sponges actually originate from bacteria living within these animals. Today, scientists report that sponges themselves, not their resident microbes, produce at least one promising group of compounds. They will present their results at ACS Spring 2022.
“The Invisible Extinction” chronicles the pioneering work of globetrotting microbiome researchers Martin Blaser and Maria Gloria Dominguez-Bello
Researchers at the University of Illinois Chicago are looking at the possibility that gastroenterological changes could be an early warning sign for Lou Gehrig's disease. Their research in animal models also shows a promising treatment to slow the disease’s progression.
Bile acids, well known for their role in dissolving fats and vitamins, are also important players in gut immunity and inflammation.
If you’ve been hitting the gym and getting results, you know it’s time to strut your stuff; and it turns out bacteria feel the same way.
Natural microbial communities contain multiple species of bacteria, making it difficult to isolate and culture individual bacterial species. Two new tools allow researchers to genetically manipulate distinct bacterial species within their communities. Combined, these tools give researchers the ability to track genetic modifications as the community grows and to examine gene function in microorganisms that cannot be grown in the lab.
It is well known that methane, a greenhouse gas, is produced by special microorganisms, for example in the intestines of cows, or in rice fields. For some years, scientists had also observed the production of methane in plants and fungi, without finding an explanation.

A Rutgers researcher’s new formula with Investigational New Drug (IND) status has successfully alleviated a patient’s long-term severe gastrointestinal (GI) illness associated with post-acute COVID-19 syndrome, or long-haul COVID, in a recent study. The study’s results on the formula developed by Liping Zhao, Ph.D., are now published in an article titled “Nutritional Modulation of Gut Microbiota Alleviates Severe Gastrointestinal Symptoms in a Patient with Post-Acute COVID-19 Syndrome” in mBio, a peer-reviewed journal of the American Society for Microbiology.
Colleen Hansel, senior scientist in the Marine Chemistry and Geochemistry Department at Woods Hole Oceanographic Institution (WHOI), has been elected as a Fellow of the American Academy of Microbiology within the American Society of Microbiology (ASM). Sixty-five fellows from around the world, including Hansel, were inducted into the Class of 2022 for their records of scientific achievement and original contributions that have advanced microbiology.

“Inulin from Jerusalem Artichoke (Sunroot)” an innovation from Chula Faculty of Medicine helps maintain the balance of gut microbiota, and reduce obesity, is to be developed into a prebiotic functional health-boosting food for all ages.
Microbes interact with each other in many ways, including theft. Methanotrophs, methane-consuming microbes, need copper to convert methane and have evolved strategies to collect copper by producing a special compound. But some methanotrophs actively “steal” this compound from others. This makes them more competitive and controls how the overall community consumes methane.
Gut bacteria brew all sorts of chemicals, but we don’t know what most of them do. A new study suggests that one such compound, previously linked to cancer, may serve as a bizarre weapon in microbial skirmishes.

Wildfires destroy and alter carbon in forests. The remaining carbon can be difficult for many organisms to consume. New research shows that one type of fungi thrives after wildfires because it has genes that allow it to feed on carbon altered by fires. The research helps to explain how carbon returns to the food web after a fire.
