NewsResearch team traces evolutionary history of bacterial circadian clock on ancient Earth
To better understand the circadian clock in modern-day cyanobacteria, researchers studied ancient timekeeping systems. They examined the oscillation of the clock proteins in modern cyanobacteria, comparing it to the function of ancestral Kai proteins.

NewsPapua New Guinea eliminates trachoma as a public health problem
Papua New Guinea (PNG) has been validated by the World Health Organization (WHO) for eliminating trachoma as a public health problem. Trachoma, the world’s leading infectious cause of blindness, no longer poses a public health threat in the country.

NewsLight-to-electricity nanodevice reveals how Earth’s oldest surviving cyanobacteria worked
An international team of scientists have unlocked a key piece of Earth’s evolutionary puzzle by decoding the structure of a light-harvesting “nanodevice” in one of the planet’s most ancient lineages of cyanobacteria.

NewsNew treatment targets link between viral infection and Alzheimer’s disease
A unique mechanism triggering Alzheimer’s disease draws attention: viral infection—while ALT001 is confirmed to alleviate neuroinflammation and suppress viral replication.

NewsThe Global Fund to fight AIDS, Tuberculosis and Malaria ‘should step up efforts’
The international community must protect global responses to HIV, tuberculosis (TB), and malaria to serve humanity’s collective interests, according to a new opinion article.

NewsWorld’s largest bat organoid platform paves the way for pandemic preparedness
Researchers have created the world’s most comprehensive bat organoid platform. These ’mini-organs’ are grown from five common bat species found across Asia and Europe and represent four different organs—airway, lungs, kidneys, and small intestine.

NewsClimate change is turning coastal lagoons into ‘salty soup’
The impacts of human activity and climate change are coalescing to make coastal lagoons saltier, changing the microbial life they support and the function they play in their ecosystems, according to new research.

NewsScientists evaluate in-vitro activity of ceftazidime-avibactam against carbapenem-resistant gram-negative bacteria
Scientists explored the in-vitro activity of ceftazidime-avibactam (CAZ-AVI) in clinical isolates of carbapenem-resistant gram-negative bacteria collected at the outpatient, emergency, and inpatient departments of the Indus Hospital, Karachi.

NewsResearchers reveal lipid-based communication between body and gut microbes
A new study shows how a host protein can specifically recognize bacterial lipids, thus triggering beneficial immune responses. It also highlights a new way the body actively shapes the gut microbiome by communicating with microbes to maintain balance.
-
NewsScientists reveal key bacterial immune mechanism
Researchers have uncovered a pivotal mechanism by which bacteria defend themselves against viral infection. Cyclic dinucleotides (CDNs), synthesized during activation of the cyclic oligonucleotide-based anti-phage signaling system (CBASS) immune mechanism, trigger the filamentous assembly of phospholipase effectors, which execute the downstream immune response.

NewsTough microbes found in NASA cleanrooms hold clues to space survival and biotech
A new study involving AMI member Professor Alexandre Rosado has reported 26 novel bacterial species growing inside cleanrooms associated with NASA space missions. They carry genetic traits associated with resilience to extreme environments.

NewsEchidna microbiome changes while mums nurse puggle
Research shows microbial communities in echidna pseudo-pouches undergo dramatic changes while the animal is lactating, which could help in creating an environment for their young, known as puggles, to thrive.

NewsActivating ‘jumping genes’ speeds up bacterial evolution from decades to weeks
Scientists have developed a system to control and accelerate the evolution of changes in the bacterial genome structure, targeting small ‘jumping genes’, or DNA sequences known as insertion sequences.

NewsCOVID-19 caused by the Omicron variant in lung transplant recipients: a single center case series
A new study investigates the risk factors for developing severe disease in lung transplant patients as a result of the Omicron variant of Covid-19.

NewsHeart rhythm disorder traced to bacterium lurking in our gums
A new study finds that a gum disease bacterium can slip into the bloodstream and infiltrate the heart. There, it drives scar tissue buildup—known as fibrosis—distorting the heart’s architecture, interfering with electrical signals, and raising the risk of atrial fibrillation (AFib).

NewsMicrobial ‘phosphorus gatekeeping’ found at center of study exploring 700,000 years of iconic coastline
A new study has dug deep into the past of the coastal dunes of an iconic Queensland location in a bid to better understand how microscopic processes in the soil support some of the most biodiverse landscapes on Earth.

NewsAntibiotics taken during infancy linked to early puberty in girls
Girls given antibiotics during their first year of life, especially in the first three months, are more likely to enter puberty at an earlier age, according to new research.

NewsProbiotic supplementation may help reduce chemotherapy side effects in breast cancer
A new study shows that probiotics with seven strains have a potential effect in patients with breast cancer, especially in the improvement of common chemotherapy-related side effects such as fatigue and nausea.

NewsTissue geometry drives bacterial infection: new mechanism uncovered
Researrchers have uncovered a novel mechanism by which tissue geometry regulates bacterial infection dynamics. The study employs a multidisciplinary approach to reveal how host tissue structure, mechanical forces, and cellular signaling shape infection patterns.

NewsResearchers reveal how fungi ‘manipulate’ the course of tumors
In pancreatic ductal adenocarcinoma (PDA), the abnormal colonization of fungal communities has become a research hotspot. New research indicates that Malassezia is not only a ’marker’ in the tumor microenvironment but also a potential driver of cancer development.
