NewsDeleting 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?

NewsGut microbiome features predict devastating disease affecting preemies
In a discovery that challenges long-standing assumptions about necrotizing enterocolitis, researchers have identified previously unknown predictors for the disease. They found that bacteria-infecting viruses and bacterial antibiotic resistance genes in the gut microbiomes of babies are additional harbingers of necrotizing enterocolitis.

NewsWhat you need to know about rabies after recent North Carolina cases
In late August, the North Carolina Department of Health and Human Services confirmed multiple rabies cases in baby goats at a mobile petting zoo based in Iredell County. Hundreds of people may have been exposed to rabies from the goats when the zoo visited various locations over a five-week period.

NewsFirst-of-its-kind preventative phage therapy provides promising results
The mammalian gut microbiome is teeming with a delicate balance of bacteria and the phages that keep them in check. What if the phages in the gut could prepare for an orally ingested pathogen and strike it down as it enters the gut, negating the need for a battle?

NewsStudy supports effectiveness of RSV preventive antibody treatments for infants and provides new way to monitor viral resistance
An analysis of more than 60,000 respiratory syncytial virus (RSV) sequences from around the world found that viral variants associated with resistance to current RSV prevention tools remain rare, according to a study.

NewsResearchers discover how Epstein-Barr Virus triggers multiple sclerosis attacks
In a study of blood samples from more than 100 participants with MS, researchers detected increased EBV lytic activity in immune cells up to three months before MS relapse and discovered that these cells also showed elevated expression of genes linked to MS risk.

NewsHedgehog coronaviruses may threaten cats more than humans, new study finds
Researchers have discovered how a group of coronaviruses circulating in hedgehogs invades host cells, a key to understanding their potential to jump between species and their risk of causing a pandemic in humans.

NewsLab tackles antibiotic resistance across multiple fronts in new trio of studies
To defeat multidrug-resistant superbugs, bacterial defenses must be confronted wherever they may emerge, from basic genetic mutations in a laboratory, to complex real-world transmission in hospital rooms. A new trio of studies demonstrates how an integrated approach might yet expose and overcome these diverse survival mechanisms.

NewsBeyond the gut: Necrotizing enterocolitis drives neurodevelopmental impairment through gut-derived inflammation
A severe gut disease in premature infants, known as necrotizing enterocolitis (NEC), does far more than damage the intestines—it fundamentally alters brain development, leaving up to 40% of survivors with lasting cognitive, motor, and behavioral impairments.

NewsBacteria in airway shape air pollution health risk
A study suggests that the subtype of the bacterium Streptococcus pneumoniae, together with air pollution exposure impacts the rate and timing of invasive disease — with some strains linked to immediate infection after air pollution exposure, and some taking several weeks.

NewsMosquito waste reveals viruses hiding in plain sight
When public health researchers want to know whether diseases such as COVID-19 or polio are circulating in a community, they can look for genetic evidence in wastewater. Source: Dana Price/Rutgers University Dana Price of the Rutgers Center for Vector Biology sets a mosquito-waste collection trap in the field ...

NewsHow to build an evolutionary trap for viruses
When a virus mutates, the world usually finds out the hard way. Variants of influenza and SARS‑CoV‑2 can slip past vaccines and antibody drugs before scientists fully understand what has changed. A new study suggests the hard way may not be inevitable.

NewsScientists discover why shingles pain can last after virus is gone
Researchers have discovered that small particles in the blood called exosomes are the likely culprit behind why some people with shingles experience lingering pain long after virus has cleared their body.The study investigated the cause of post-herpetic neuralgia (PHN) in patients infected with the varicella zoster virus.

NewsFecal microbiota transplantation may improve immunotherapy-related colitis
Targeting the gut microbiome with fecal microbiota transplantation may help cancer patients with immunotherapy-related colitis avoid the need for steroids and other immune-suppressing treatments, according to researchers.

NewsFewer infections, more azithromycin use seen among emergency c-section patients following publication of clinical trial results
Researchers investigated if azithromycin use and postpartum infection rates changed after publication of trial evidence in 2016 among US pregnant women who underwent an unscheduled cesarean delivery.

NewsImmunization to prevent RSV in infants reduced ICU admissions by 97 per cent
A new immunization, offered free to all infants through universal programs in two Canadian provinces, provided strong protection against respiratory syncytial virus, commonly referred to as RSV, sharply reducing hospitalizations and intensive care unit (ICU) admissions in infants.

NewsMultiplexed 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.

NewsResearchers discover first PLP-dependent enzyme that influences bacterial protein production
Researchers discovered aminovaleramididine synthetase (AvaS), the first pyridoxal phosphate (PLP)-dependent enzyme involved in tRNA modification, expanding scientific understanding of how RNA shapes the reading of genetic information. The discovery reveals a previously unknown mechanism that bacteria use to regulate protein production.

NewsFertilizers and extreme heat are damaging coral reefs in the Gulf of Mexico
Scientists analyzing nitrogen isotopes in the calcareous skeletons of corals have discovered that the high levels of nitrogen in the northern Gulf originate from the Mississippi River and are attributable to the use of fertilizers.

NewsWhat 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.
