News Sea stars show surprising resilience after disease outbreak
A decade after sea star wasting disease devastated ochre sea star populations along the U.S. West Coast, new research suggests that the epidemic shifted populations from a stable, adult-dominated state to one marked by fluctuations in sea star sizes and ages.

NewsBiochemists search for cellular vulnerabilities in killer ‘superbugs’
Helen Zgurskaya and Valentin Rybenkov are leading a five-year, $5.3 million project funded by the National Institute of Allergy and Infectious Diseases to find new ways to deliver lifesaving drugs directly into resistant pathogens.

NewsResearchers discover novel phage DNA modifications that offer new hope against antibiotic-resistant superbugs
A groundbreaking discovery reveals a unique way phages modify their DNA with arabinose sugars to protect themselves from bacterial defence systems. Natural DNA phage modifications occur at a higher rate than previously predicted, the study revealed.

NewsThe fart factor: researchers get wind of hydrogen’s role in the gut
Scientists have revealed how hydrogen is made and used in the human gut. Though infamous for making farts ignite, hydrogen also has a positive role supporting gut health.

NewsCOVID-19 vaccination linked to reduced infections in children with eczema
Children with atopic dermatitis (AD), commonly known as eczema, may experience fewer infections and allergic complications if they receive the COVID-19 vaccine, according to new research.
-
NewsUrban fungi are showing signs of thermal adaptation
A new study finds that common fungal species may be adapting to higher temperatures in warmer sites within cities compared to cooler sites in the same city. The findings could signify that urban fungi could one day evolve into disease-causing pathogens.

NewsNew research demonstrates ’living metal’ could bridge the gap between biological and electronic systems
Researchers are pioneering ‘living metal’ composites embedded with bacterial endospores, paving the way for dynamic communication and integration between electronic and biological systems.

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.
