NewsHow bacteria use a protein associated with Alzheimer’s to fight off threats
Amyloids are perhaps best known as a key driver of Alzheimer’s disease. According to new research, these oft-maligned proteins also serve a critical role for bacteria in our environment, enabling them to fight off other “predatory bacteria.”

NewsH5N1 found in dairy cattle retains preference for infecting birds, representing low risk to humans
Avian influenza virus from the ongoing outbreak in dairy cattle appears to be keeping its bird-infecting features rather than adapting to better infect other mammals, according to a new study.

News‘Major leap in bioelectronic sensing’: researchers turn bacteria into tiny pollution detectors
Researchers have engineered E. coli to act as living multiplexed sensors, allowing these genetically modified cells to detect and respond to multiple environmental toxins simultaneously by converting their biological responses into readable electrical signals.

NewsStudy reveals how climate shapes fungal spore traits with applications for soil health
A new study reports on how global climate conditions affect arbuscular mycorrhizal fungal spore traits and the species biogeographic patterns. The study is the first to examine multiple traits of this kind on a global scale.

NewsHow fungus powers plant life in extreme environments
A new experiment suggests dark septate endophytes (DSEs) may be capable of linking the roots of neighboring plants to facilitate water sharing and boost their host’s biomass, and may even be keeping plant networks alive in drought-prone areas.

NewsNew tool helps predict antibiotic resistance
Researchers have developed a platform that identifies drug resistance genes already circulating in the environment before they emerge in the clinic and directly couples this information to the design of resistance-evasive antibiotics.

NewsAntiviral treatment fails to slow early-stage Alzheimer’s
A clinical trial has found that a common antiviral for herpes simplex infections, valacyclovir, does not change the course of the disease for patients in the early stages of Alzheimer’s.

NewsTrapping gut bacteria’s hidden fuel improves blood sugar and liver health, study shows
Scientists have discovered a surprising new way to improve blood sugar levels and reduce liver damage: by trapping a little-known fuel made by gut bacteria before they wreak havoc on the body. It could open the door to new therapies to treat metabolic diseases.

NewsNew research uncovers gut microbe-derived metabolites as potential therapy for obesity-related metabolic disorders
New research reveals that certain gut microbial byproducts may hold promise as a novel therapy for obesity-associated metabolic complications by restoring critical hormone-producing cells in the intestine.

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.
