NewsFree webinar: Nuts, bolts and getting down to brass tacks in the expanding universe of microbiome stewardship
In a fascinating free webinar from the Microbes and Social Equity 2026 Speaker Series, Dr Robert Beiko PhD will take a step back to examine a fundamental question at the heart of microbiome stewardship: what exactly are we trying to protect, and why?

NewsSmall bowel microbiome offers clues to women’s health
A new study has identified differences in the makeup and organization of the small bowel microbiome between women and men. One intriguing finding was a bacterial community containing Granulicatella, found only in women.

NewsBlueberry’s waxy shield reveals clues to gray mold resistance
Botrytis cinerea is a broad-host-range necrotrophic fungus that causes gray mold in more than 1,000 plant species. In blueberry, it can damage flowers in the field and later emerge as fruit rot after harvest, reducing shelf life, shipment quality and market value. The disease is especially challenging because latent infections ...

NewsBacteria can make testosterone. What could that mean for prostate cancer?
Scientists have identified an unexpected participant in androgen chemistry: a bacterium from the human urinary tract that can convert the steroid precursor DHEA into testosterone under laboratory conditions. It reveals a previously unknown microbial route to a hormone that is central to prostate biology.

NewsResearchers find C. difficile colonization in infants reshapes gut development
Practically since its discovery, the highly contagious bacterium Clostridioides difficile has been reported to not cause symptoms in infants. But new findings suggest that the bacterium can reshape the developing infant gut and may have long-term consequences.

NewsResearchers test far-ultraviolet light to prevent bird flu in poultry
Researchers are preparing to test a new potential line of defense against highly pathogenic avian influenza, HPAI in poultry farming. They will use a form of ultraviolet light called far-UVC, to see if it can kill HPAI, without harming birds on poultry farms.

NewsThe body doesn’t just absorb a plant-based diet—it adapts to one, new review finds
A new review of plant-based diets concludes that the body actively adapts to sustained dietary change, absorbing iron more efficiently, synthesizing more of its own creatine and carnosine, using protein more economically, and remodeling gut bacteria to better ferment fiber.

NewsVaricella zoster virus can cause serious disease beyond chickenpox and shingles
New research is shedding light on the surprisingly broad range of neurological and systemic diseases that can be caused by varicella zoster virus (VZV), the virus that causes chickenpox and shingles.

NewsCancer medication helps reduce SIV reservoir, increases hope for HIV cure
Researchers have provided the first proof-of-concept in a nonhuman primate model for eliminating HIV-infected cells with venetoclax, a clinically approved medication for cancer.

NewsUnderground methane leaks may cultivate microbes that help consume them
Researchers have identified where naturally occurring soil microbes consume methane released from underground natural gas leaks. Methane-consuming microbes were most active in a narrow zone near the surface where methane rising from below meets oxygen entering from the atmosphere.

NewsWhere do dissimilatory iodate-reducing microorganisms live in the ocean?
Scientists have discovered that dissimilatory iodate-producing microorganisms do not live above marine oxygen minimum zones (OMZs) as long predicted - instead thriving within the OMZs, converting iodate into iodide and promoting the release of marine iodine into the atmosphere.

NewsAnti-fouling materials protect against slimy incursions
Researchershave received a $750,000 grant from the U.S. Department of Defense to develop materials that incorporate soft robotics and nontoxic polymers to fight biofouling, or the buildup of aquatic organisms in wet environments.

NewsWild tomatillos coat fruits with sticky chemical arsenal, study finds
For decades, research on plant chemical defenses has focused on glandular trichomes—the tiny hair‑like structures on leaves and stems that produce and secrete protective compounds. Acyl sugars, a class of specialized metabolites widespread in the nightshade family (Solanaceae), are known to deter insects and fungal pathogens when produced in leaf ...

NewsImmune drug anifrolumab linked to lower risk of infection and hospitalization for skin lupus
Preliminary results from an investigator-initiated single-site clinical study show that some people with chronic cutaneous lupus erythematosus are less likely to acquire life-threatening infections when taking the drug anifrolumab.
