NewsStudying yeast in the gut could lead to new, better drugs
A new study sheds light on the behavior of yeast cells in the gut, paving the way for new lines of yeast that more efficiently produce therapeutic drugs tailored to address specific diseases.

NewsStudy reveals key differences in long-term brain effects of COVID-19 and flu
While both Covid and flu can leave lasting lung damage, only SARS-CoV-2 infection caused persistent brain inflammation and small blood vessel injury, even after the virus was no longer detectable, a new study has found.

NewsNew strategies aim at HIV’s last strongholds
A new study has overcome a long-standing challenge—how to isolate and study elusive HIV-infected cells called authentic reservoir clones (ARCs) that evade the immune system, making the disease difficult to cure.

NewsA single gene, a dramatic change: CRISPR unlocks white strawberries
Researchers used CRISPR/Cas9 to selectively edit a single dominant gene copy controlling fruit color in the commercial octoploid strawberry cultivar ‘Florida Brilliance’. By targeting the MYB10-1B gene, they successfully converted red strawberries into stable white-fruited plants.

NewsA parasitic origin for the ribosome?
Scientists propose that the ribosome first emerged from a proto-ribosome, likely a viral parasite, which began by taking advantage of proto-cells, and ended up being incorporated into cells, at some time before the last universal common ancestor.

NewsNew study finds sex and menopause-based differences in presentation of early Lyme disease
In a new study, researchers found that male and female patients with early Lyme disease present with different signs of the disease in the symptoms they report, their physical exams and their laboratory test results.

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.
