Researchers at the University of Malaga have identified a molecular mechanism that allows Bacillus cereus to build protective biofilms, a discovery that could lead to new methods for eradicating persistent foodborne and hospital-acquired infections. The study, published in Science Advances, details how the proteins TasA, CalY, and CapP coordinate to form a bacterial “shield” that … Read more
A daily probiotic supplement may enhance treatment outcomes for older adults diagnosed with moderate depression, according to a pilot clinical trial published in the Journal of the American Geriatrics Society. Researchers found that patients taking Lactobacillus helveticus and Bifidobacterium longum alongside standard antidepressants experienced greater improvements in mood and anxiety symptoms than those taking a … Read more
Deformed Wing Virus type A (DWV-A) triggers behavioral instability in honeybees by disrupting neuronal homeostasis and sensory perception, according to a study published in Scientific Reports. Researchers found that oral infection leads to the downregulation of glutamatergic system genes and creates a “behavioral asynchrony,” where bees simultaneously exhibit traits of both nurses and foragers. This … Read more
Researchers at the University of Pittsburgh School of Public Health have identified that H5N1 bird flu infects dairy cattle primarily through specific N-linked sialic acid receptors found in mammary glands, rather than the respiratory tract. This discovery explains why the virus causes severe mastitis in cows instead of traditional respiratory symptoms, providing a new framework … Read more
Researchers at the University of Pennsylvania have identified a new class of potential antibiotics hidden within prions, the misfolded proteins typically associated with fatal neurodegenerative conditions. By using the deep-learning platform APEX 1.1 to scan 19.3 million protein fragments, the team discovered 1,179 antimicrobial candidates—dubbed “prionins”—that can kill drug-resistant bacteria, according to findings published in … Read more
Microbes are the first responders to climate change, colonizing barren land exposed by retreating glaciers long before plants can take root. A study conducted by researchers at Monash University, published in the scientific literature, found that these pioneer microbial communities utilize metabolic flexibility to survive in nutrient-poor, high-stress environments. By consuming trace gases like hydrogen … Read more
Montana State University researchers have identified a biological pathway that allows cells to produce the essential amino acid cysteine when primary systems fail, a process previously deemed impossible by the scientific community. Published May 21 in Nature Chemical Biology, the discovery reveals how mammalian cells utilize a backup mechanism to cleave carbon-sulfur bonds in cystine, … Read more
Invasive raccoons are a primary source of Escherichia albertii contamination in environmental water, according to a study published in Applied and Environmental Microbiology by researchers at Osaka Metropolitan University. The study found that 56% of sampled raccoons carried the bacterium, which is linked to severe human food poisoning, suggesting that wildlife—rather than human activity—drives the … Read more
New research presented at ASM Microbe 2026 identifies a critical link between gut microbes, bile acids, and cardiovascular complications in sleep apnea patients. According to the American Society for Microbiology, targeting the farnesoid X receptor (FXR) may offer a new path for preventing heart and metabolic damage caused by the disorder, which affects millions worldwide. … Read more
A Silent Threat: What the Brazilian Porcupinepox Virus Means for Wildlife Conservation In the lush, biodiverse landscapes of Brazil’s Federal District, a quiet crisis has been unfolding. Recent scientific investigations have shed light on the Brazilian porcupinepox virus (BPoPV), a pathogen that is proving to be a significant threat to the survival of the free-ranging … Read more
