NewsMicrobes drastically change behavior outside the lab
New research shows that corn root bacteria behave completely differently when grown on a plant rather than in a lab, underscoring the importance of studying microbes in their natural setting, rather than relying solely on laboratory research.

NewsResearchers identify rapidly spreading genetic variants that make parasites resistant to malaria treatment
New genetics study helps explain declining malaria drug susceptibility and highlights the urgent need to track mutations and improve current therapies.

NewsCell ‘invisibility cloaks’ could offer side-effect-free diabetes treatment
New research suggests manufacturing cells an “invisibility cloak” out of a jelly-like material known as hydrogel, may offer an easier, less damaging treatment pathway for people with diabetes undergoing cell therapy.

NewsUC San Diego receives $12.3 million grant to study the intersection of HIV and methamphetamine use
A newly funded programme aims to use a multidisciplinary approach focused on improving the clinical care and brain health of people with HIV who also have an active methamphetamine use disorder.

NewsCells use a little-known molecule to protect themselves from iron overload
New research shows that cells rely on an unexpected protector against elevated iron levels: small molecules called polyamines. These small molecules act like storage lockers for iron, safely holding the metal in a non-reactive state until cells need it.

NewsCould beneficial bacteria help prevent the body from absorbing lead?
New funding supports early-stage research at Worcester Polytechnic Institute that aims to show how pieces of genetic code produced in the gut by healthy bacteria could block lead exposure.

NewsVanderbilt health evaluating vaccine for C. difficile for people 65 and older
Investigators are enrolling participants in a Phase 3 clinical trial testing an investigational vaccine against Clostridioides difficile, a contagious bacterial infection of the colon.

NewsCould preventing shingles also help prevent dementia?
A new study finds that older adults who received a shingles vaccine had a 24% lower risk of developing dementia over four years. The findings add to growing evidence that preventing shingles may also protect against neurological disease.

NewsDrought is reshaping the spread of infectious diseases
A review study reveals how drier conditions could make humans and wildlife more vulnerable to certain infectious diseases, even though many parasites and disease-carrying organisms depend heavily on water to survive.

NewsPlant pathologist selected as Fulbright Distinguished Scholar
Heather Kelly, field crops pathologist in the University of Tennessee Department of Entomology and Plant Pathology, has received a prestigious Fulbright Distinguished Scholar Award for two one-month trips to Brazil in 2026 and 2027.

NewsReddit reveals what pregnant women really want to know about the Tdap vaccine
An analysis of Reddit posts about the maternal Tdap vaccine made by pregnant women reveals expectant mothers turning to Reddit to seek advice and reassurance—with fewer outright instances of vaccine hesitation/refusal than has generally been observed for other types of vaccines, according to a study published on August 12, 2026 ...

NewsWorld’s first oral microbiome-based nanomedicine to supercharge anti-cancer immunity
Researchers have successfully developed the world’s first oral, microbiome-based nanomedicine which enhances the ability of immune cells to attack cancer cells.

NewsFungi enhance hydrogels for stronger, safer materials
New research uses a natural substance from fungi, called chitin, to create hydrogels that are both significantly stronger and tougher.

NewsAncient bacterial signals from cell powerhouses may fuel excessive inflammation
Researchers have discovered that proteins released from mitochondria can activate the immune system in a similar way to invading bacteria, suggesting that remnants of mitochondria’s evolutionary past may contribute to inflammation.

NewsNew study shows how Toxoplasma parasite evolved to adapt to crowded conditions in host cells
How Toxoplasma reshapes its metabolism to keep growing under crowded conditions in a tissue cyst has been unclear. A new study identifies a parasite-specific protein that helps coordinate this response, allowing Toxoplasma to manage oxidative stress.

NewsScientists reconstruct past ocean temperatures from red algae
Researchers have found a new way to reconstruct daily seawater temperatures over a four-month period. The key lies in rhodoliths: nodule-like calcareous structures formed by red algae that occur in oceans worldwide.
-
NewsResearchers look at ‘genetic neighborhoods’ to find pathogenic bacteria
Researchers used a machine-learning approach to study not just which genes a bacterium has, but also where those genes sit next to each other, helping to distinguish disease-causing strains of a poultry pathogen from nonpathogenic strains.

NewsTriple-dose regimen may permanently clear HIV in infected newborns
New research suggests a one-time regimen of therapies given to newborns within three days of birth could permanently clear HIV infection.

NewsCorn stalks. It’s what’s for dinner … If you’re a microbe
Engineers have developed a strain of a common bacterial species, Pseudomonas putida, that can feed exclusively on the three major sugars present in corn stalks, with broader implications for the future of biomanufacturing.

NewsLargest real-world study finds early flu antiviral treatment reduces ICU admissions in hospitalized children
A new US-wide study finds antiviral treatment is linked to fewer intensive care unit (ICU) admissions and shorter hospital stays for children hospitalized with influenza.
