NewsUnlocking how bacteria bounce back after antibiotics
A groundbreaking study has uncovered how Escherichia coli (E. coli) persister bacteria survive antibiotics by protecting their genetic instructions. The work offers new hope for tackling chronic, recurring infections.

NewsLess is more: Gene loss drives adaptive evolution of a pandemic bacterium
A study reveals a surprising evolutionary insight: sometimes, losing genes rather than gaining them can help bacterial pathogens survive and thrive. The research focused on Vibrio parahaemolyticus, a bacterium behind many of the seafood-related infections worldwide.

News‘Migrion’ – a chimeric structure of virus and migrasome, a novel unit for intercellular viral transmission
Researchers found that in infected cells, nucleic acids and proteins of vesicular stomatitis virus (VSV) are actively transported into migrasomes, newly characterized cellular structures generated specifically during cell migration.

NewsResearchers uncover relationship between gut fungi, human genetic variation and disease risk
A study uncovers evidence of the first ternary relationships between human genetic variation, variation in gut mycobiome, and risk of developing chronic disease.

NewsAncient mammoth remains yield the world’s oldest host-associated bacterial DNA
An international team has uncovered microbial DNA preserved in woolly and steppe mammoth remains dating back more than one million years. The analyses reveal some of the world’s oldest microbial DNA ever recovered, as well as the identification of bacteria that possibly caused disease in mammoths.

NewsStudy detects multidrug-resistant KPC-producing bacteria in Chilean wastewater for the first time
A team of Chilean researchers has identified, for the first time in the country, the presence of KPC-type carbapenemase-producing bacteria in wastewater samples from the Greater Concepción Metropolitan Area.

NewsMicroalgae are more significant for carbon dioxide absorption in the Southern Ocean than previously thought
14,000 years ago, algal blooms in the Southern Ocean helped to massively reduce the global carbon dioxide content of the atmosphere – as has now been revealed by new analyses of ancient DNA. Declines in sea ice pose a serious threat to these algae.

NewsTiny ocean partnership between algae and bacteria reveals secrets of evolution
The microscopic alliance between algae and bacteria offers rare, step-by-step snapshots of how bacteria lose genes and adapt to increasing host dependence, a new study shows.

NewsOne shot of RSV vaccine effective against hospitalization in older adults for two seasons
One shot of an RSV vaccine protects adults ages 60 or older from RSV-associated hospitalization and critical illness during two consecutive RSV seasons, according to a new study.

NewsMicrobiologists uncover bacteria that remove toxic sulfide and use iron minerals for growth
An international team of scientists has discovered a new microbial metabolism: so-called MISO bacteria “breathe” iron minerals by oxidizing toxic sulfide. The previously unknown biological process sees versatile microbes remove toxic sulfide and use it for their growth.

NewsBacteria survive dust storms and introduce new genetic traits into our air
Bacterial communities carried from Africa to Israel survive their airborne journey, arriving with genes that may affect human health and the environment, a new study reveals.
-
NewsBroad-specificity enzyme targets glycans from across the kingdoms of life
Researchers have found a new enzyme that has a much broader specificity than the leading alternatives. This analysis resulted in the identification of the PNGaseL enzyme taken from Flavobacterium akiainvivens, which is a microbe isolated from decaying wood of a Hawai’ian plant.

NewsStudy finds significant health benefits from gut microbes transfer
A cohort of overweight teens who received fecal transfer eight years ago were found to have reduced risk for a series of metabolic changes which can lead to heart disease, stroke and diabetes, compared with the participants who received the placebo.
-
NewsNew study finds concerning sea star response to an algal neurotoxin
Researchers found potentially concerning concentrations of the neurotoxin domoic acid in sea stars even in the absence of the algal blooms that are thought to drive DA outbreaks.
-
NewsNew sepsis diagnostic could reduce critical time to save patients
A new diagnostic method would confirm sepsis infections earlier, cutting critical hours in the “race against time” to save patients’ lives. The process uses a centrifuge to separate bacteria from blood cells, and automatic microscopy for detection.
-
NewsNew ‘cough simulator’ mimics TB transmission with unprecedented accuracy
Researchers have developed a new experimental system called Transmission Simulation System (TSS) that replicates the airborne transmission of TB – by simulating the human cough – with unparalleled realism and never-before-seen precision.
-
NewsHow plants rot: New method decodes hidden decomposers of wood and leaves
Researchers have developed a new method to identify the molecular tools that different species use to decompose dead plant material. Their analysis of over 18,000 species found that some invertebrates also evidently have a whole range of such tools at their disposal.

NewsGuideline on respiratory infections in leukemia revised
People with leukemia have a weakened immune system due to the disease itself and treatment, which leads to an increased susceptibility to infections. In a revised guideline, experts summarize the findings of the past ten years on all viruses that cause respiratory infections.
-
NewsPioneering raspberry genome editing technique could be the future of fruit and farming
Researchers have published a new method to edit the DNA of raspberries, with the goal of creating more sustainable raspberry production and less food waste. Protoplasts were gene edited with CRISPR-Cas9, which can be programmed to target any region of the genome.

NewsPertussis resurgence in Tuscany outlines importance of timely vaccination in Italy
Research analysing 2016-2024 data from all pertussis-related hospitalisations in Tuscany, Italy, finds a ninefold increase in pertussis cases in 2024 among children and adolescents.
