NewsExpert consensus on clinical applications of fecal microbiota transplantation for chronic liver disease
To assist clinicians in rapidly mastering and standardizing the clinical application of FMT for chronic liver disease, an expert consensus has been developed to address key aspects of FMT application and provide reference and guidance for clinical practice.

News‘Trojan horse’ may deliver toxic dose of copper to bacterial colonies, including drug-resistant MRSA infections
A research team is developing a drug that works in combination with copper to kill bacteria, including those that cause MRSA, a type of staph infection that is resistant to usual treatments.

NewsHow a single gene shapes gut health and IBD risk
Two recent studies highlight the role of a gene called PTPN2 in protecting the gut from harmful bacteria linked to inflammatory bowel disease (IBD). When PTPN2 does not function properly, the gut becomes more vulnerable to infection and inflammation.

NewsMethane eating microbes turn a powerful greenhouse gas into green plastics, feed, and fuel
Methane eating microbes could help turn a powerful greenhouse gas into everyday products like animal feed, green plastics, and cleaner fuels, according to a new scientific review of fast moving research on these unusual bacteria.

NewsHow a potential antibiotics ban could affect apple growers
Antibiotic resistance in human and animal health is on the forefront of public debate, but it’s a less well-known issue in plant agriculture. However, antibiotics are important tools in fruit production, and their efficacy hinges on avoiding resistance in disease-causing bacteria. Source: Tianna DuPont, WSU Extension Apple ...

NewsEndogenous retroviruses promote early human zygotic development
New findings offer insight into why some embryos fail to develop past zygotic genome activation (ZGA), pointing to an unexpected root of human infertility.

NewsSecret of youth: New study shows gut microbiota directly regulates intestinal stem cell aging
A new study reveals that age-related changes in the gut microbiota directly impair intestinal stem cell (ISC) function and that restoring a youthful microbial environment can reverse this decline.

NewsScientists synthesize medicarpin in baker’s yeast
Scientists have developed a way to synthesize medicarpin in yeast. Like palitaxel in the 1990s, this tumor-attacking sustance has only limited natural quantitites and is considered difficult to synthesize.

NewsPIXL Max: Automated colony picker breaks records for speed and accuracy
With the latest innovation from the team at Singer Instruments, a new standard for speed and repeatability in microbial colony pickers has been achieved through the integration of cutting edge AI technologies.

NewsBreath carries clues to gut microbiome health
Researchers have shown that disease-associated bacteria in the gut can be detected through exhaled breath. They found that chemicals released by gut microbes and captured from the breath of children and mice can reveal the composition of the bacteria living in the intestines.

NewsThe hidden microbial communities that shape health in space
A new Perspective article sets out a path to uncover the role of biofilms in health during long-duration spaceflight, and how spaceflight research can reshape our understanding of these microbial communities on Earth.

NewsChemotherapy rewires gut bacteria to curb metastasis
Researchers report that chemotherapy-induced damage to the intestinal lining alters nutrient availability for gut bacteria, reshaping the microbiota and increasing the production of indole-3-propionic acid (IPA), a tryptophan-derived microbial metabolite.

NewsEvidence of ‘lightning-fast’ evolution found after dino-killing asteroid impact
The asteroid that struck the Earth 66 million years ago devastated life across the planet, wiping out the dinosaurs and other organisms. But new research shows new species of plankton appeared fewer than 2,000 years after the world-altering event.

NewsBacteria use wrapping flagella to tunnel through microscopic passages
A new study shows that certain symbiotic bacteria wrap their rotating flagella around their cell bodies to form a “screw thread.” This configuration lets them propel forward through one-micrometer-wide passages, such as those inside insect guts, that would otherwise trap or immobilize them.

NewsNexaBiome accelerates development of novel diabetic foot treatment with Scottish Enterprise funding
UK biotechnology company NexaBiome Life Sciences Ltd has received continued funding from Scotland’s national economic development agency, Scottish Enterprise, to accelerate its breakthrough bacteriophage technology for the treatment of diabetic foot infections (DFIs).

News‘Antimicrobial resistance pandemic will kill more people than cancer by 2050 and no one at Davos is talking about it’
Scientists speaking at Frontiers Science House at Davos warned that antimicrobial resistance (AMR) will be the next “pandemic” like COVID-19, killing more people than cancer by 2050. They urged immediate global action against AMR.

NewsSniffing out the cause of keratoderma-associated foot odor
The distinct foot odor that comes with the skin disorder Nagashima-type palmoplantar keratosis (NPPK) is caused by the overgrowth of a specific bacterial strain. Topical application of benzoyl peroxide restores balance in the bacterial skin flora, reducing the odor.

NewsLow vitamin D levels shown to raise risk of hospitalization with potentially fatal respiratory tract infections by 33%
Severe vitamin D deficiency is associated with a higher rate of hospitalisation for respiratory tract infections such as bronchitis and pneumonia. Scientists found that those with a severe deficiency (below 15 nnmol/L) were 33 per cent more likely to be admitted to hospital for treatment.

NewsScientists solve 66 million-year-old mystery of how Earth’s greenhouse age ended
Experts studying foraminifera fossils have discovered that concentrations of calcium in the sea dropped by more than half across the last 66 million years, which likely caused Earth’s massive drop in temperature.

NewsMajor clinical trial provides definitive evidence of impacts of steroid treatment on severe brain infection
A major UK clinical trial has shown that adding the corticosteroid dexamethasone to standard antiviral treatment for encephalitis, caused by herpes simplex virus (HSV) does not improve long-term outcomes overall, although early use may lead to better recovery.
