NewsResearch teams will develop automated compost monitoring system
Composting turns organic waste into nutrient-rich material, but improper temperature and moisture control can allow pathogens to survive and increase safety risks. Researchers have received a $362,000 grant to develop an automated sensor network to improve monitoring of compost piles.

NewsResearchers engineer bacteria capable of consuming tumours from the inside out
A research team is developing a novel tool to treat cancer by engineering hungry bacteria to literally eat tumours from the inside out. They added a gene to the organism from a related bacterium that can better tolerate oxygen and found a way to activate the oxygen-resistant gene at just the right time.

NewsThe hidden infections that refuse to go away: how household practices can stop deadly diseases
A 13-year study reveals why a deadly parasitic infection targeted for elimination in China persisted in some areas even after decades of control. The research investigated some of the last pockets of schistosomiasis in the country, finding that farming practices and unsafe sanitation contributed to disease spread.

NewsBiocodex Microbiota Foundation announces open call for projects for $50,000 2026 USA Microbiome Research Grant
The Biocodex Microbiota Foundation, an independent organization founded by Biocodex, has opened applications for its 2026 USA research grant. The $50,000 grant will be awarded to a U.S.-based investigator studying the gut microbiota and its relationship to human health and disease.

NewsElevated E. coli, staph still detected in Potomac river 4 weeks after sewage spill
Nearly a month after a wastewater pipe broke and spewed hundreds of millions of gallons of raw sewage into the Potomac River just north of Washington, D.C., the latest water testing results continue to show high levels of E. coli and S. aureus, including antibiotic-resistant MRSA.

NewsNew single-cell transcriptomic clock reveals intrinsic and systemic T cell aging in COVID-19 and HIV
Scientists developed a new single-cell transcriptomic clock called T immune cell transcriptomic clock (Tictock) to measure aging in specific immune cells. They found that in patients with acute Covid-19, the infection increased the biological age of naïve CD8 T cells.

NewsScientists home in on Acinetobacter baumannii’s resistance evolution
Scientists have found a way to understand how Acinetobacter baumannii is evolving - and how best to strategize a fight against it. They have produced a huge whole-genome look at the rise of this resistance, pointing the way to new strategies in staying ahead of the pathogen.

NewsHoly Grail: One vaccine may provide broad protection against many respiratory infections and allergens
In a new study in mice, researchers have developed a universal vaccine formula that protects against a wide range of respiratory viruses, bacteria and even allergens.

NewsPersonalized predictions of probiotic and prebiotic therapy success by computer models
A new study demonstrated that computer models of gut metabolism can predict which probiotics will successfully establish themselves in a person’s gut and how different prebiotics affect production of health-promoting short-chain fatty acids.

NewsPrenatal infection increases risk of heavy drinking later in life
Exposure to infection and other immune stress in the womb increases the likelihood of alcohol misuse in adulthood, a risk that may be reduced through prenatal antioxidant treatment, a new study shows.

NewsResearchers discover novel bacteria in Florida’s stranded pygmy sperm whales
Researchers have identified three previously unknown genotypes of Helicobacter bacteria living inside stranded pygmy sperm whales. The study represents the first documented occurrence of these unique Helicobacter genotypes – now designated Kogia Helicobacter 1, 2 and 3 – in pygmy sperm whales.

NewsA break in a longstanding mystery about origin of complex life
One of our microbial ancestors was part of a group called the Asgard archaea, which today live primarily in the deep sea and other oxygen-free spaces. Now scientists have found that some Asgards use, or at least tolerate oxygen.

NewsInvasive death cap mushrooms are changing their chemistry
Scientists have just published new research about the chemistry of death cap mushrooms (Amanita phalloides) - the species is not only spreading rapidly as an invasive fungal species in the United States, but the move across continents has changed the chemistry of the species.

NewsNovel vaccine protects against C. diff disease and recurrence
A novel vaccination approach cleared the harmful gut bacterium Clostridioides difficile in an animal model of infection. An experimental vaccine administered to the mucosal lining of the colon protected against illness, death, tissue damage and infection recurrence.

NewsExposing a hidden anchor for HIV replication
Scientists investigating HIV have revealed a previously unknown role for the viral protein integrase, which helps HIV insert itself into human DNA. A new study provides the first direct evidence that integrase plays a critical structural role earlier on in HIV’s life cycle — when the virus matures into an infectious force.

NewsGlobal scientific paper establishes first consensus definition of gut health
A global group of 13 scientists and clinicians is helping establish clarity by publishing a consensus definition of gut health. They define gut health as “a state of normal gastrointestinal function without active gastrointestinal disease and gut-related symptoms that affect quality of life.”

NewsComplexity key to preventing infection after heart surgery
Research indicates that uniform materials could be the culprit behind deadly infections that can occur when using synthetic materials for cardiovascular grafts.
-
NewsMacrophage immune cells need constant reminders to retain memories of prior infections
Researchers have discovered that immune cells known as macrophages remain poised to fight repeat infections due to the persistent presence of signaling molecules left behind during previous infections.

NewsPower grids to epidemics: study shows small patterns trigger systemic failures
Why do some systems collapse suddenly after what seems like a minor disturbance? In nature, a local disease outbreak can quickly escalate into an epidemic. New research suggests that in many cases, the key isn’t the entire system – but its smallest building blocks.

NewsCOVID-19 vaccination during pregnancy may help prevent preeclampsia
A new multinational study has found that COVID-19 vaccination during pregnancy, particularly when combined with a booster dose, significantly reduces the risk of preeclampsia, a serious and potentially life-threatening pregnancy complication.
