Bacteria in airway shape air pollution health risk
A study suggests that the subtype of the bacterium Streptococcus pneumoniae, together with air pollution exposure impacts the rate and timing of invasive disease — with some strains linked to immediate infection after air pollution exposure, and some taking several weeks.
Gut bacterial enzyme worsens colitis by switching off a protective intestinal signal
Microbiome research often focuses on which microbes are present in the gut and what small molecules they produce. But gut bacteria also make enzymes that can act directly on molecules produced by the host. Researchers report that one such bacterial enzyme can weaken a protective intestinal signal and aggravate colitis in a preclinical model.
Mosquito waste reveals viruses hiding in plain sight
When public health researchers want to know whether diseases such as COVID-19 or polio are circulating in a community, they can look for genetic evidence in wastewater.
How to build an evolutionary trap for viruses
When a virus mutates, the world usually finds out the hard way. Variants of influenza and SARS‑CoV‑2 can slip past vaccines and antibody drugs before scientists fully understand what has changed. A new study suggests the hard way may not be inevitable.
Scientists discover why shingles pain can last after virus is gone
Researchers have discovered that small particles in the blood called exosomes are the likely culprit behind why some people with shingles experience lingering pain long after virus has cleared their body.The study investigated the cause of post-herpetic neuralgia (PHN) in patients infected with the varicella zoster virus.
Dogs and cats carry antibiotic-resistant bacteria also found in people, study finds
Pets may carry strains of Klebsiella pneumoniae — a potentially serious bacterium that can cause infections that are also found in humans. The study is the first to map the global genetic makeup of K.pneumoniae carried by domestic dogs and cats, and to compare it on a large scale with the same bacteria in people.

Sharpening an essential tool for biotechnology
Scientists develop a database of validated guide RNAs to improve engineering of microbes for manufacturing applications.
Green hydrogen production and storage using alcohols, iron, and baker’s yeast
A new recyclable system uses baker’s yeast to store H₂ in organic molecules and iron ions to release it when needed - offering a promising route toward more sustainable hydrogen production and storage.
Creating yeast strains that aren’t picky eaters
Scientists have engineered yeasts that can simultaneously use different sugars in biomass crops.
Multiplexed saliva-based immunodiagnostics for assessing anti-flavivirus immunity
Researchers have unveiled a saliva-based assay that rapidly, accurately, and noninvasively assesses flavivirus immunity by measuring multiple antibody classes in saliva.
Intermediate nitrification/denitrification bioreactor closes a gap
Researchers present a method for nitrification and denitrification of septic effluent comprising an intermediate nitrification/denitrification bioreactor which builds on concepts currently used in the design of full‑scale wastewater treatment plants.
Engineering bacterial surfaces with glucan nanofilms creates a potent vaccine platform against invasive fungal infections
A research team has developed a synthetic bacterium-based vaccine platform that uses engineered bacterial surfaces to assemble glucan nanofilms for enhanced antifungal immunity against pathogens such as Candida albicans.
Major investment to unlock the potential of protist research
A new collaboration will tackle major technical challenges currently limiting protist genomics, helping to unlock the potential of protist research for biomanufacturing, sustainable agriculture and environmental applications.
What low vaccination rates in the US could mean for flu season 2026
Experts reveal what to expect this flu season, when to get the flu shot, how to recognize flu symptoms, how to treat it, and what the newly approved mRNA flu vaccine means for the public.
