NewsToxoplasmosis: How a deadly parasite infects its host cells
Researchers have discovered how the parasite Toxoplasma gondii builds a specialised structure that allows it to move and invade host cells. They identified two proteins that control how the conoid complex is assembled - this acts like an engine for movement and cell-invasion.

NewsBiochar boosts hydrogen and methane yield in next-generation food-waste-to-energy systems
A research team has demonstrated that adding biochar to two-phase anaerobic digestion systems can significantly increase hydrogen and methane production from food waste, while maintaining system stability under high organic loading rates.

NewsAll life copies DNA unambiguously into proteins. Archaea may be the exception.
A study shows how a methane-producing member of the Archaea, interprets one three-letter sequence — normally a stop codon that signals the end of a protein — in two different ways, synthesizing two different proteins seemingly at random, though biased by conditions in the environment.

NewsProbiotics and prebiotics offer safer alternatives to antibiotics in animal agriculture
A new study shows how probiotics, prebiotics, and synbiotics can safely enhance growth and immunity in livestock, and balance the growth of intestinal microbes, offering practical alternatives to antibiotics.

NewsPositive signs in the fight against superbugs: CHINET 2024 surveillance report
The 2024 CHINET antimicrobial resistance surveillance report uncovers a hopeful trend in China’s battle against bacterial resistance, with a significant reduction in resistance among several key pathogens.

NewsPathogens are the biggest threats at festivals and mass gatherings
A comprehensive review led by public health experts reveals that infectious disease outbreaks and foodborne illnesses are the most common public health threats at youth-focused mass gatherings, ranging from music festivals and cultural celebrations to sporting and religious gatherings.

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.
