NewsApproach to combat antibiotic resistance turns bacterium’s genes against it
Scientists have found that a structurally modified version of the drug florfenicol exploits drug resistance mechanisms in Mycobacterium abscessus to amplify the effect of the antibiotic perpetually.

NewsAntimicrobial peptides can reduce salmonella in chickens
A new study has found that antimicrobial peptides can combat Salmonella infections in chickens, a major cause of foodborne disease in the U.S. This discovery could help improve food safety and protect public health without relying on antibiotic use.

NewsResearchers pinpoint target for treating virus that causes the stomach bug
Human astroviruses are a leading viral cause of the stomach bug, often leading to vicious cycles of sickness and malnutrition. New research reveals the strategy that the human astrovirus uses to enter the body.

NewsCOVID-19 during pregnancy linked to higher risk of neurodevelopmental disorders in children
Children born to mothers who had COVID-19 while pregnant face an elevated risk of developmental disorders by the time they turn 3 years old, including speech delays, autism, motor disorders, and other developmental delays, according to new research.

NewsResearchers to investigate moisture-driven Antarctic ice sheet growth during past warm climates
Investigating how increased moisture transport to Antarctica, and under what temperatures and sea ice conditions moisture transport occurs, is required to understand the mechanisms that can lead to increased ice accumulation.

NewsDiscovery of viral entry routes into cells points to future prevention, treatment strategies
Researchers have identified central routes that two deadly viruses take to invade human cells and have designed decoy molecules that block the infections. The discoveries set the stage for developing new prevention and treatment strategies for yellow fever virus and tick-borne encephalitis viruses.

NewsResearch spotlight: Mapping how gut neurons respond to bacteria, parasites and food allergy
A new study adds to accumulating evidence showing that the enteric nervous system works closely with the immune system to help the body respond to bacteria, parasites and allergens. The ENS also plays a key role in how the body maintains balance and protects itself from harm.

NewsGlobal Virus Network welcomes new centers of excellence across the Americas
The Global Virus Network (GVN), a coalition of leading medical virologists representing 80+ Centers of Excellence and Affiliates in 40+ countries, has announced the addition of three new Centers of Excellence.

NewsNew study explores ‘legacy effects’ of soil microbes on plants across Kansas
A new study analyzes soils sampled across the state of Kansas to determine the importance of “legacy effects” — or how soils from a specific location are influenced by microbes that have evolved in response to the specific climate at that site for many years.

NewsBabies’ gut bacteria may influence future emotional health
A child’s early gut microbiome may influence their risk of developing depression, anxiety or other internalizing symptoms in middle childhood, according to a new study.

NewsSome acute and chronic viral infections may increase the risk of cardiovascular disease
In the weeks following a bout of influenza or COVID, the risk of heart attack or stroke may rise dramatically, and chronic infections such as HIV may increase the long-term risk of serious cardiovascular disease events, according to new, independent research.

NewsAI and citizen science reveal potential first detection of invasive malaria mosquito in Madagascar
Researchers used AI and citizen science to identify what may be the first Anopheles stephensi mosquito ever detected in Madagascar — a species capable of spreading deadly malaria across urban Africa. A single smartphone photo submitted through NASA’s GLOBE Observer app led to the discovery.

NewsViral infections at the heart of why honey bees overthrow their queen
Common viral infections shrink a queen bee’s ovaries, reducing both her egg-laying capacity and her production of methyl oleate, a pheromone that normally keeps worker bees loyal. When methyl oleate levels drop, workers will “smell” the queen’s weakness - and begin preparing her successor.

NewsScientists to probe how microbes break down water-soluble polymers in wastewater
Scientists and industry have teamed up to investigate how microbes in wastewater interact with and potentially biodegrade polymers called viscosifiers.

NewsMissing nutrient in breast milk may explain health challenges in children of women with HIV
A new study reveals that breast milk from women living with HIV contains significantly lower levels of tryptophan, an essential amino acid likely important for infant immune function, growth, and brain development.

NewsScientists develop novel gene therapy for hereditary hearing loss
Scientists have introduced an innovative gene therapy method to treat impairments in hearing and balance caused by inner ear dysfunction. The treatment holds promise for treating a wide range of mutations that cause hearing loss.

NewsRebalancing the gut: how AI solved a 25-year Crohn’s disease mystery
Researchers have settled a decades-long debate surrounding the role of the first Crohn’s disease gene to be associated with a heightened risk for developing the auto-immune condition.

NewsScientists identify cells by seeing how high they levitate
A new cell-sorting device uses electromagnetic levitation to precisely direct the movement of cells. It can be used to separate different types of cells — cancer cells from healthy cells, or live cells from dead cells, for example — with many potential applications in the lab and in the clinic.
