Gut viruses contribute to human health, but provoke inflammation when perturbed

Research in recent years has demonstrated the diverse roles that gut bacteria can play in health and disease, but what about contributions from viruses, which, like bacteria, perpetually reside within the human intestine?

Cryo-EM imaging of STING protein reveals a new binding source for immune attacks

In new research, UT Southwestern scientists report that imaging a key immunity protein known as STING at near-atomic resolution reveals a previously undiscovered binding location that appears to be crucial for launching immunological attacks.

Understanding the role of ORF8 viral gene in COVID-19 infection and outcomes

A research team led by Jae Jung, PhD, Director of Cleveland Clinic's Global Center for Pathogen & Human Health Research, has uncovered the critical role a viral gene, ORF8, plays in infection and disease outcomes of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19.

Researchers uncover a treasure trove of new data about RNA viruses

Ocean water samples collected around the world have yielded a treasure trove of new data about RNA viruses, expanding ecological research possibilities and reshaping our understanding of how these small but significant submicroscopic particles evolved.

Rockefeller scientists reveal how a narrow-spectrum antibiotic selectively targets C. diff

Most antibiotics are double-edged swords. Besides killing the pathogen they are prescribed for, they also decimate beneficial bacteria and change the composition of the gut microbiome.

Chemical component geosmin’s taste makes bacteria-eating worms at risk

Geosmin has a distinct smell that pervades the air after a summer rainstorm or fills your nose when gardening. It smells like moist dirt—earthy and somewhat comfortable.

Gut microbiota may play a role in resistance to blood pressure medicines

Almost half of the U.S. adult population has high blood pressure - or hypertension - and about 20% of these patients have treatment-resistant hypertension.

Researchers discover a unique technique to fight hospital-borne disease

A study team developed an early-stage therapy that sabotages the pump and restores antibiotic efficiency by disclosing the structure of a protein needed by bacteria to pump out antibiotics.

UC Riverside scientists aim to find how some fungi and bacteria manage to thrive post-wildfires

Scientists have found microbes living in the charred soil that wildfires leave behind. They don't know how some fungi and bacteria manage to thrive when everything else has died, but a new project aims to change that.

Multiple nanobodies effectively block infection with different SARS-CoV-2 variants

Researchers at Karolinska Institutet in Sweden have developed a novel strategy for identifying potent miniature antibodies, so-called nanobodies, against emerging SARS-CoV-2 variants.

Study reveals why infected individuals cannot get rid of HIV altogether

Thanks to antiretroviral therapy, HIV infection is no longer the life sentence it once was. But despite the effectiveness of drugs to manage and treat the virus, it can never be fully eliminated from the human body, lingering in some cells deep in different human tissues where it goes unnoticed by the immune system.

Tuberculosis causes early epigenetic aging in cells, study finds

In the current study, scientists at Baylor College of Medicine identified that the cells of humans and animals that recovered from tuberculosis had prematurely aged up to 12 to 14 years.

Salmonella strains in birds do not harbor antimicrobial-resistance genes, study finds

Although many wild birds carry Salmonella, the strains of the bacteria they convey usually do not harbor antimicrobial-resistance genes, according to Penn State researchers, who led a team conducting a new, nationwide study.

Study reveals novel mechanism used by infectious bacteria to survive stressful situations

A new study led by researchers at University of Utah Health details a novel mechanism that infectious bacteria use to quickly adjust to environmental stress. The discovery could help explain why certain types of common infections-;such as urinary tract and bloodstream infections like sepsis- are hard to get rid of.
