NewsGroundbreaking technique unlocks secrets of bacterial shape-shifting
Scientists have long known that bacteria come in many shapes and sizes, but understanding what those differences mean has remained a major challenge, especially for species that can’t be grown in the lab. A groundbreaking method could change how researchers study bacterial diversity.

NewsLargest study of nose microbiome helps highlight those at risk of staph aureus infection
People who persistently carry Staphylococcus aureus (S. aureus) in their nose have fewer species of other bacteria, while certain bacteria may help to prevent S. aureus colonisation, according to the findings of the largest-ever study of the nasal microbiome.

NewsThe mystery of the missing deep ocean carbon fixers
New findings challenge the current view of how carbon dioxide is “fixed” in the sunless ocean depths. The study presents results that help to reconcile discrepancies in accounting for nitrogen supply and dissolved inorganic carbon (DIC) fixation at depth.

NewsAnts signal deadly infection in altruistic self-sacrifice
Researchers have discovered that terminally ill ant brood, like infected cells, release an odor signaling their impending death and the risk they pose. This sophisticated early warning system facilitates rapid detection and removal of pathogenic infections.

NewsAsia PGI and partners unveil preview of PathGen: New AI-powered outbreak intelligence tool
Asia Pathogen Genomics Initiative (Asia PGI) has offered the first public preview of PathGen, an AI-powered sense-making and decision-making support platform of pathogen genomics and contextual data.

NewsA molecule opens a breach in HIV, providing access to its reservoirs
An international team has unveiled how a molecule capable of opening the “shell” of HIV improves the elimination of infected cells. The study demonstrates how a new CD4-mimetic compound, CJF-III-288, modifies the HIV envelope protein structure to allow for a better immune response.

NewsResearchers rescue antibiotics from resistance using phototherapy
Researchers have used phototherapy to inhibit a protein in E. coli bacteria that makes them resistant to antibiotics. This new method, if proven safe and effective in living organisms, holds promise for rescuing the effectiveness of antibiotics that bacteria have become resistant to.

NewsResearchers identify why some people with HIV achieve remission after antibody treatment
Researchers have discovered why some people living with HIV who are given broadly neutralizing anti-HIV antibodies (bNAbs) can safely stop taking standard, lifelong HIV medications and maintain control of the virus for years, while others given the same treatment do not achieve this remission.

NewsVIRE: a global data platform to better understand viruses
Researchers have released a comprehensive viral genome database covering diverse ecosystems to advance the understanding of viral evolution and ecosystem functions.

NewsThe immune system creates its own targets within viruses
A new study reveals that our immune system does more than defend against viruses. In certain cases, it induces mutations within viruses that make them easier to recognize later on.

NewsBridging controversy: New international guidelines redefine diagnosis and treatment of fungal eye infections
A global expert panel from the Asia-Pacific region has now issued 20 consensus statements providing comprehensive, evidence-based guidance for the diagnosis and management of a sight-threatening condition - fungal endophthalmitis.

NewsPoint-of-care rapid tests can improve screening for latent tuberculosis
A new test shows promising results for detecting latent tuberculosis infection in resource-limited settings. Latent tuberculosis is often diagnosed using a laboratory test called QuantiFERON-TB Gold Plus - this was compared with another test, TB-Feron.

NewsResearchers discover latent antimicrobial resistance across the world
A team of researchers has discovered that latent antimicrobial resistance is more widespread across the world than known resistance. They call for broader surveillance of resistance in wastewater.

NewsMicroalgae could play key role in bio-based circular economy
With food systems under pressure from climate change, geopolitical instability, and supply chain vulnerabilities, the EU is driving innovation toward more sustainable, resilient, and local production models. Microalgae have emerged as a promising resource for producing ingredients across food, feed, and other consumer goods. Source: Hannah ...

NewsMucosal virome and host transcriptome interactions reveal viral influence in colorectal polyp development
A new study has provided the first integrated mucosal virome-transcriptome landscape of colorectal polyps, the precursors of colorectal cancer, offering new insights into viral-host interactions at this early disease stage.

NewsPlant extracts show promise in reducing human pathogen risks in agricultural soils
A new study has revealed that natural plant extracts can significantly lower the risks posed by human bacterial pathogens in manure amended agricultural soils. The eco friendly strategy disrupts the communication systems that bacteria use to coordinate harmful activities.

NewsA viral fitness-constraint strategy exploits the structural and functional limitations of viral evolution
Researchers have revealed two innovative strategies for the development of durable and broadly neutralizing antibodies against SARS-CoV-2. Their study proposes the immune trajectory strategy and the viral fitness-constraint strategy.

NewsNew global guidelines streamline environmental microbiome research
A team of nearly 250 researchers from 28 countries has developed a new set of reporting guidelines for environmental microbiomes called STREAMS. The guidelines are organized by the structure of a scientific manuscript and help ensure that important details aren’t overlooked.

NewsDynamic duo of bacteria could change Mars dust into versatile building material for first human colonists
Scientists are investigating a bacterial co-culture mixed with Martian regolith as a potential feedstock for 3D printing on Mars. At the intersection of astrobiology, geochemistry, material science, construction engineering, and robotics, this synergistic system could revolutionize the potential for construction on the Red Planet.

NewsCorticosteroid use does not appear to increase infectious complications in non-COVID-19 pneumonia
A systematic review and meta-analysis found that adjunct corticosteroids probably reduce short-term mortality in cases of severe pneumonia and acute respiratory distress syndrome and may reduce secondary shock in severe pneumonia.
