Scientists develop microbially produced adhesive materials from glucose instead of petroleum
Researchers have demonstrated the potential of using microorganisms to produce a bio-based alternative to petroleum-derived materials for hot-melt adhesives.Using Escherichia coli, the team produced a new polymer from glucose and demonstrated performance and properties that support its potential use as a hot-melt adhesive.
Novel database reveals hidden diversity and potential of deep-sea microbes
Scientists have spearheaded Global Ocean Reference Genomes Dark (GORG-Dark), the first global atlas of single-cell microbes living in the aphotic ocean. It contains more than 9,600 genomes from individual microbial cells collected across a broad range of depths and locations, including the Mariana Trench and the Antarctic.
Two coronavirus master keys: new study unveils the mechanisms Covid-19 virus uses to enter our cells
To enter our cells, the Covid-19 virus fuses its surrounding membrane with the membrane of the target cell. The fusion peptides of the spike protein function as molecular keys that allow the virus to open the door to the target cell . A new study shows that SARS-CoV-2 does not have just one key, but two.
New test could dramatically speed diagnosis of hard-to-detect lung infections
Nontuberculous mycobacteria can cause chronic, tuberculosis-like lung infections. Researchers have developed a new diagnostic platform that can identify the precise species of bacteria causing a patient’s infection in just a few hours — a dramatic improvement over the current standard, which can take four to six weeks.
New method reveals how virus particles can build themselves, molecule by molecule
Researchers have captured the step-by-step assembly of individual virus-like particles, revealing how simple molecular interactions can reliably build these complex biological structures. The process works rather like finding a route through a maze in which only the productive turns lock into place.
Your gut makes a molecule that fights a leading cause of food poisoning
Researchers have discovered that a molecule called indole can inhibit the growth of Campylobacter jejuni, a leading cause of food poisoning worldwide. Their study builds on years of research aimed at understanding how C. jejuni manages to thrive in the gut and cause disease.

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.
Deleting yeast DNA to save lives
People with weakened immune systems and some other conditions can experience an overgrowth of Candida yeasts, leading to a type of infection known as candidiasis. It might be possible to save these patients by using CRISPR to delete the very genes that let infectious Candida resist treatment - but which genes are responsible?
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.
