NewsWhy you may get future vaccines via dental floss
Researchers have demonstrated a novel vaccine delivery method in an animal model, using dental floss to introduce vaccine via the tissue between the teeth and gums. It stimulates the production of antibodies in mucosal surfaces, such as the lining of the nose and lungs.

NewsTiny artificial cells can keep time, study finds
A team of researchers has shown that tiny artificial cells can accurately keep time, mimicking the daily rhythms found in living organisms like cyanobacteria. Their findings shed light on how biological clocks stay on schedule despite the inherent molecular noise inside cells.

NewsEconomically disadvantaged patients at greater risk for long COVID
A study found that people with social risk factors including economic instability and food insecurity at the time of COVID-19 infection were at greater risk for long COVID.

NewsStudy identifies gene clusters in rhizobia linked to robust legume growth
A new study identified clusters of rhizobial genes that appear to move rapidly through bacterial populations and drive greater plant biomass in host plants. Understanding the interplay of host and bacterial genomes will help to optimize plant growth by improving the rhizosphere.

NewsAI poised to revolutionize Lyme disease testing and treatment
Researchers unveiled a blood test developed with the help of artificial intelligence (AI) that identifies Lyme disease sooner and more accurately than the current standard — and that could translate to vastly improved patient outcomes.

NewsNew study unlocks molecular defense against devastating potato pathogen
A team of plant scientists has made a significant breakthrough in understanding how potato plants defend themselves against a soilborne pathogen that causes powdery scab, an emerging and economically damaging disease affecting potato crops worldwide.

NewsEngineers take a closer look at how a plant virus primes the immune system to fight cancer
Scientists took a closer look at how the cowpea mosaic virus (CPMV), unlike other plant viruses, is uniquely effective at activating the body’s immune system to recognize and attack cancer cells.

NewsFungicides intended to suppress turfgrass diseases may damage fairways
Golf course managers have much more insight into which fungicides to use to suppress turfgrass diseases, such as the common and costly dollar spot disease, without damaging the grass on their fairways, thanks to a new study.

NewsGut microbiome may predict “invisible” chronic fatigue syndrome and long COVID
Millions suffering from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) may be closer to personalized care, according to new research that shows how the disease disrupts interactions between the microbiome, immune system, and metabolism.

NewsBird-to-human jump by trichomonas parasites illuminated in new study
A new study reveals how genetic changes in the parasite responsible for one of the world’s most common sexually transmitted infections may have helped it adapt to human hosts.
-
NewsHow plants are learning to spot sneaky bacterial invaders
Scientists used artificial intelligence to help plants recognize a wider range of bacterial threats — which may lead to new ways to protect crops like tomatoes and potatoes from devastating diseases.

NewsNew AI tool accelerates mRNA-based treatments for viruses, cancers, genetic disorders
A new artificial intelligence model can improve the process of drug and vaccine discovery by predicting how efficiently specific mRNA sequences will produce proteins, both generally and in various cell types.

NewsScientists call for urgent policy reform to accelerate cross-border coral restoration efforts
An international team of coral scientists is calling for urgent regulatory reform to support assisted gene flow (AGF)—a powerful tool to boost coral resilience—before climate change causes further reef decline and irreversible damage to coral ecosystems.

NewsImmunity to seasonal flu protects against severe illness from bird flu in ferrets
A study in ferrets — which have remarkably similar respiratory systems to humans — suggests that widespread immunity to H1N1 seasonal influenza virus may explain why exposure to H5N1 bird flu causes only mild symptoms in humans.

NewsNewly discovered ‘sixth sense’ links gut microbes to the brain in real time
Researchers have uncovered what they call a “neurobiotic sense,” a newly identified system that lets the brain respond in real time to signals from microbes in our gut. Tiny sensor cells lining the colon’s epithelium detect a microbial protein and send rapid messages to the brain.

NewsUnderground Atlas: First global map of fungal biodiversity reveals 90% conservation gap
The Underground Atlas is the first digital map predicting Earth’s underground mycorrhizal fungal biodiversity. The work analyzed 2.8 billion DNA sequences from 130 countries revealing that over 90% of mycorrhizal biodiversity hotspots lie outside protected areas.

NewsStealth genetic switch in mosquitoes halts malaria spread
Biologists have created a CRISPR-based gene-editing system that changes a single molecule within mosquitoes, stopping the malaria-parasite transmission process. Genetically altered mosquitoes are still able to bite those with malaria, but the parasites can no longer be spread to other people.

NewsInappropriate prescriptions for antibiotics, glucocorticoids and opioids common at urgent cares
Urgent care visits commonly result in inappropriate prescriptions of antibiotics, glucocorticoids or opioids, researchers have warned.

NewsHow does infection with respiratory syncytial virus affect the health of older adults?
Adults aged 65 and older hospitalized for RSV in Ontario experienced significantly higher rates of adverse outcomes such as longer length of hospital stay, transfer to intensive care, and 30-day mortality, compared with patients hospitalized with influenza, urinary tract infection, or fracture.

NewsProbiotics can help or hinder gut recovery after antibiotic treatment
All probiotics are not created equal, according to new research. In a mouse model, researchers found that different probiotic strains can either accelerate or delay the gut microbiome’s recovery after antibiotic treatment.
