NewsProposed cuts to foreign aid could result in millions of HIV deaths, new modelling study estimates
New modelling analysis suggests that proposed funding cuts by major donor countries to foreign aid could undo decades of progress made to end HIV/AIDS as a public health threat and new infections and deaths could surge back to levels not seen since the early 2000s.

NewsScientists unlock frogs’ antibacterial secrets to combat superbugs
Researchers exploited natural peptides derived from frogs and improved their structural designs as antibiotic candidates, which are effective against complex mock bacterial communities of drug-resistant pathogens in preclinical tests, sparing beneficial microbiota and human cells.

NewsResearchers find live hantavirus is carried in various New Mexico small mammal species
A study was carried out to find out the reasons why human cases of the sin nombre hantavirus were concentrated in one particular region of New Mexico, even though the virus was found in 30 species of rodents and small mammals endemic to a different region.

NewsCorrecting imbalance with the gut microbiota after stroke could reduce brain inflammation
An imbalance in ligands, which are molecules produced by the body and the gut microbiota, can affect a key receptor protein that plays a role in brain inflammation after stroke, according to researchers.

NewsMeasles elimination versus eradication: The difference explained
As of March 13, the CDC has confirmed 301 cases of measles as well as the death of a child in Texas. Amira Roess, an epidemiologist and professor of global health, clarifies the benefits of vaccinating children and adolescents against measles.

NewsAntibiotic exposure in infancy may boost Type 1 diabetes risk - but microbiota can help
Exposure to antibiotics during a key developmental window in infancy can stunt the growth of insulin-producing cells and may boost risk of diabetes later in life. But the research pinpoints specific microbes that may help those critical cells proliferate in early life.

NewsThe gut microbiota-metabolites-brain axis mediates social behavior dysfunction following anaesthesia
New research shows that the anaesthetic Sevoflurane (Sev) influences social functioning via the gut-brain axis, with microbiota-derived bile acids serving as critical mediators in this pathway.

NewsTadpoles try to flee dangerous virus in their pond by growing much faster than normal
A new study shows that larvae of wood frogs respond to the presence of a deadly ranavirus by growing and maturing precociously. In response to ranavirus, tadpoles change their growth, development, and resource allocation, which may help them tolerate the energetic demands of infection or escape risky environments to avoid infection.

NewsC. diff uses toxic compound to fuel growth advantage
The pathogen C. diff — the most common cause of health care-associated infectious diarrhea — can use a compound that kills the human gut’s resident microbes to survive and grow, giving it a competitive advantage in the infected gut.

NewsResearchers achieve de novo biosynthesis of plant lignans using synthetic yeast consortia
Researchers have achieved the biosynthesis of the antiviral ingredient lignan glycoside in yeast Saccharomyces cerevisiae. By mimicking the spatial and temporal regulation of plant biosynthesis, they designed a system with obligated mutualism, enabling metabolic division of labor among different yeast strains.
