NewsAvian flu could push vulnerable vulture populations into further decline
H5N1 avian influenza is emerging as a serious threat to already vulnerable vulture populations, with deaths reported across the Americas and Europe. Researchers warn that losing these scavengers could also weaken a natural barrier against disease by allowing infected carcasses and pathogens to persist for longer.

NewsMarine compound shows promise against deadly brain-eating amoeba
A compound isolated from a marine bacterium may offer a faster way to attack Naegleria fowleri, the amoeba responsible for one of the deadliest known brain infections. In laboratory tests, rutamycin B reached full potency within four hours and was far more toxic to the parasite than to human cells.

NewsScientists propose national microbiome plan to prevent chronic disease
Leading microbiome researchers are calling for a global ‘moonshot’ to determine how the microbes living in and on our bodies contribute to chronic disease. The proposed agenda would combine long-term human studies, clinical trials, global research standards and public education to move the field from promising associations towards proven causes and treatments.

NewsTwo-in-one tool tracks viral RNA inside live infected cells in real time
The tool lets researchers film activity of Zika and chikungunya viruses in high resolution and identify virus-host interactions, a key step to developing effective antiviral strategies that could stop infections

NewsMigratory birds spread avian influenza to Greenland’s polar bears
Migrating birds that breed in the Arctic are spreading avian influenza to polar bears in eastern Greenland, according to a new study that found evidence of infections in bear blood samples acquired from Greenland Inuit subsistence hunters.

NewsScientists reveal how deadly Andes hantavirus attaches to human cells
Earlier this year, an outbreak of Andes hantavirus on a cruise ship, which killed three passengers and sickened 13, highlighted the lack of approved vaccines or treatments for the virus. Scientists now show how the virus recognizes its target on a human cell, a finding that could lead to effective therapies against Andes virus and other hantaviruses.

NewsHow clinicians can manage recurrent catheter bloodstream infections
Long-term intravenous catheters can be essential for treatment, but they also create a persistent risk of serious bloodstream infections. A new clinical review outlines how doctors can diagnose, treat and prevent recurrent infections while preserving vital vascular access whenever it is safe to do so.

NewsNew dosing data expands HIV treatment options for newborns
Newborns with HIV can now be treated with dolutegravir from the first days of life. An international clinical study identified a safe dosing regimen that produced drug levels comparable to those seen in older children and adults, helping support the FDA’s expanded approval.

NewsNeedle-free approach could offer a new way to deliver mRNA vaccines
A needle-free mRNA vaccine delivered through the skin protected mice against both SARS-CoV-2 and influenza while causing less inflammation than lipid-based formulations. The approach uses a high-pressure liquid jet and a combination of two immune-boosting adjuvants to strengthen protection without relying on conventional mRNA carriers.

NewsScientists discover migration-mediated mechanism enabling bacteria-virus coexistence
A study shows how collective movement enables viruses to persist with migrating bacterial colonies while minimizing the risk of either complete viral takeover or bacterial escape.

NewsBelgium’s top science foundation honors 'Virus Hunter'
’Virus Hunter’ Ken Stedman has been named an International Collen-Francqui Professor for the 2026-27 academic year, an honor the Francqui Foundation reserves for scientists it considers among the best in their field.

NewsFAU receives $1.3M NOAA grant to address harmful algal blooms
A new $1.3 million grant from the National Oceanic and Atmospheric Administration’s National Centers for Coastal Ocean Science will enable researchers to investigate the environmental and biological mechanisms that drive harmful algal blooms in subtropical estuaries.

NewsScientists ‘crank up’ cells’ natural defence against viruses
Researchers have found a way to amplify one of the body’s natural antiviral defence pathways, making cells significantly more resistant to infection. By boosting signalling through the protein ISG15, the approach could lead to host-directed treatments that remain effective even as viruses mutate.

NewsAdvanced air purification fails to reduce surgical infections
Cleaner operating-room air may not be enough to prevent surgical infections. In a study of more than 110,000 procedures, advanced air-purification systems did not reduce infections, complications or deaths, suggesting hospitals may gain more by targeting direct contamination of surgical wounds.

NewsCranberry juice may be a boon for oral hygiene
Pure cranberry juice may do more than add a tart kick to the holiday table. In a small human study, it slowed dental plaque growth and reduced acid production, suggesting the fruit’s natural compounds could help protect tooth enamel.

NewsLike humans, some primates become cautious of germs in the wake of a viral outbreak
Researchers found that macaque monkeys who had lived through a deadly disease outbreak became significantly more cautious about food that appeared contaminated, even though they did not know how the disease had spread. The findings suggest that pathogen-avoidance behavior can be shaped by experience, offering clues about the evolutionary roots of disgust.

NewsCan better gut health help patients with ovarian cancer tolerate chemotherapy?
A new clinical trial is testing whether probiotics can help patients with ovarian cancer better tolerate chemotherapy. The trial will look at whether probiotics can help reduce treatment side effects and improve quality of life. Researchers will also study how changes in the gut microbiome may be linked to treatment response.

NewsScientific triumph, equity failure: Faster, fairer COVID-19 vaccine roll-out could have saved millions of lives
Beginning the global COVID-19 vaccine roll-out 100 days after the virus was sequenced could have saved more than 8 million lives by the end of 2021, most of them in lower-middle-income countries. The authors of a new Policy Brief argue that fair vaccine-sharing rules should be established before the next pandemic, rather than negotiated during the crisis itself.

NewsU-M-led consortium to receive up to $52 million in NIH funding to study why viral respiratory infections affect children differently
A Michigan Medicine-led research consortium has secured approval for up to $52 million in federal funding to launch a multicenter study examining why some young children recover fully from viral lower respiratory tract infections while others develop severe illness or lasting problems such as asthma.
