NewsScientists uncover tuberculosis bacterium’s ’heartbeat’, opening door to new treatments
Scientists have identified a molecular system inside Mycobacterium tuberculosis that functions like the organism’s heart or lungs, keeping it alive. The system, known as PrrAB, helps the bacterium generate energy and breathe. When researchers used a gene-silencing tool, the bacterium died.

NewsEarly-stage clinical trial demonstrates promise of intranasal influenza vaccine in generating broad immunity
Researchers report encouraging results from an early phase clinical trial that found an experimental intranasal vaccine triggered a broad immune response against multiple strains of H5N1 ’bird flu’, highlighting the potential of mucosal immunization strategies.

NewsAI can speed antibody design to thwart novel viruses: study
Artificial intelligence (AI) and “protein language” models can speed the design of monoclonal antibodies that prevent or reduce the severity of potentially life-threatening viral infections, according to a multi-institutional study

NewsCAROSEL offers new ‘spin’ on monitoring water quality in real time - and tracking harmful algal blooms
Researchers can continuously track the exchanges of different forms of nitrogen between bottom sediments and the overlying water. Their novel approach enables measuring how much ammonium (NH₄⁺) is released from sediments in real time, multiple times a day, over an extended period.

NewsNew study finds targets for a new tuberculosis vaccine
A large-scale screen of tuberculosis proteins has revealed several possible antigens that could be developed as a new vaccine for TB, the world’s deadliest infectious disease.

NewsFoxtail barley serves as a host for fungal pathogens attacking barley
Researchers report that foxtail barley (Hordeum jubatum), a wild relative of the cultivated crop, can harbor several fungal pathogens and may play a role in the disease epidemiology of barley, potentially serving as reservoirs of inoculum to initiate some diseases.

NewsAccessible imaging technique can predict cardiac risks in patients with Chagas disease
A simple imaging exam capable of assessing myocardial deformation during contraction has emerged as a promising tool for predicting the risk of cardiac complications in patients with chronic Chagas disease.

NewsNew approach expands possibilities for studying viruses in the environment
A new method vastly improves on the existing approach for single-cell genetic sequencing, enabling scientists to read the genomes of individual cells and viral particles in the environment more quickly, efficiently, and cost-effectively.

NewsNovel technique reveals insights into soil microbe alarm clock
A new study yields clues about when dormant microscopic bacteria and fungi in soil ‘wake up’ and colonize roots, which influences plant growth and health.

NewsStudy reveals critical impact of universal cCMV screening on early detection of hearing loss in newborns
A comprehensive eight-year study reveals that approximately one-third of congenital cytomegalovirus-related hearing loss develops after the newborn period—cases that would be missed without universal screening programs.

NewsNew study reveals not all bats carry equal viral risk
A groundbreaking study sheds new light on the relationship between bats and dangerous viruses, showing that contrary to widespread assumptions, not all bats carry viruses with high epidemic potential, only specific groups of species.

NewsHow algae help corals bounce back after bleaching
A $1.1 million project will uncover how reefs regain life-giving algae after suffering from heat stress. The three-year project will use advanced imaging and living experimental systems to learn what’s happening on a cellular level when algae return to bleached reefs.

NewsBiomaterial vaccines to make implanted orthopedic devices safer
Biomaterial vaccines using pathogen-specific antigens could significantly lower patients’ risk of infection from implanted medical devices.
-
NewsLichens and drones reveal dinosaur bones
Scientists have found that certain lichen species preferentially colonise exposed dinosaur bones, creating distinctive spectral signatures that can be detected from 30 metres above ground using drones.
-
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.
