NewsHealthier, tastier kelp: food scientists boost nutrition and flavour of kombu
A team of food scientists has found a way to unlock the trapped nutrients in the edible seaweed, kombu, and replace the strong odours with more appealing scents, directly overcoming the two major challenges – limited nutrient bioaccessibility and poor sensory experience.

NewsFirst evidence of fungal pathogen becoming more deadly when co-infected with tuberculosis
Co-infection of Mycobacterium tuberculosis, together with Cryptococcus neoformans, is a grave public health concern, increasing the risk of death significantly. Researchers have found that in the presence of Mycobacteria, the fungus changed its cell density, cell diversity, and capsule size.

NewsNovel camel antimicrobial peptides show promise against drug-resistant bacteria
Researchers have identified three novel antimicrobial peptides (AMPs) from dromedary camels that effectively target multidrug-resistant bacteria, offering potential alternatives to conventional drugs.

NewsScrub typhus a threat in the home, study in South India finds
Most human scrub typhus infections could occur inside villages rather than during agricultural work, suggests new research conducted with the help of communities living in Tamil Nadu.

NewsElevated E. coli, staph still detected in Potomac river 4 weeks after sewage spill
Nearly a month after a wastewater pipe broke and spewed hundreds of millions of gallons of raw sewage into the Potomac River just north of Washington, D.C., the latest water testing results continue to show high levels of E. coli and S. aureus, including antibiotic-resistant MRSA.

NewsScientists home in on Acinetobacter baumannii’s resistance evolution
Scientists have found a way to understand how Acinetobacter baumannii is evolving - and how best to strategize a fight against it. They have produced a huge whole-genome look at the rise of this resistance, pointing the way to new strategies in staying ahead of the pathogen.

NewsHoly Grail: One vaccine may provide broad protection against many respiratory infections and allergens
In a new study in mice, researchers have developed a universal vaccine formula that protects against a wide range of respiratory viruses, bacteria and even allergens.

NewsPersonalized predictions of probiotic and prebiotic therapy success by computer models
A new study demonstrated that computer models of gut metabolism can predict which probiotics will successfully establish themselves in a person’s gut and how different prebiotics affect production of health-promoting short-chain fatty acids.
-
NewsNew insights into how bacteria control DNA synthesis open the door to next generation antimicrobials
A new study combines structural biology, biophysical characterisation and functional assays to delineate how the bacterial transcriptional regulator NrdR’s quaternary structure responds to different nucleotide states and how these changes affect its regulatory activity.

NewsNewly discovered virus linked to colorectal cancer
Researchers have discovered a previously undescribed virus in a common gut bacterium, Bacteroides fragilis. The virus appears more frequently in patients with colorectal cancer.
-
NewsResearchers discover how tuberculosis bacteria use a “stealth” mechanism to evade the immune system
New research reveals that mycobacteria release tiny packages called extracellular vesicles that fuse with the membranes of immune cells. These vesicles contain specialized lipids—fatty molecules—that make the cell membrane more rigid.

NewsResearchers discover novel bacteria in Florida’s stranded pygmy sperm whales
Researchers have identified three previously unknown genotypes of Helicobacter bacteria living inside stranded pygmy sperm whales. The study represents the first documented occurrence of these unique Helicobacter genotypes – now designated Kogia Helicobacter 1, 2 and 3 – in pygmy sperm whales.

NewsScientists discover ‘bacterial constipation’, a new disease caused by gut-drying bacteria
Scientists have found two gut bacteria working together that contribute to chronic constipation. The duo, Akkermansia muciniphila and Bacteroides thetaiotaomicron, destroy the intestinal mucus coating essential for keeping the colon lubricated and feces hydrated.

NewsMissing microbes in UK infant gut and probiotics highlighted by global microbiome atlas
A global atlas mapping two key gut bacteria in infants around the world has uncovered a treasure trove of bacterial strains adapted to the infant gut and not found in commercial probiotic products. It lays the foundation for more effective, tailored infant probiotics.

NewsAncestral motif enables broad DNA binding by NIN, a master regulator of rhizobial symbiosis
Researchers investigated the molecular mechanisms whereby the transcription factor NODULE INCEPTION (NIN) - crucial for rhizobial symbiosis - can bind a broader spectrum of DNA sequences than its close homologs, using the legume Lotus japonicus (Miyakogusa) as a model system.

NewsNovel vaccine protects against C. diff disease and recurrence
A novel vaccination approach cleared the harmful gut bacterium Clostridioides difficile in an animal model of infection. An experimental vaccine administered to the mucosal lining of the colon protected against illness, death, tissue damage and infection recurrence.

NewsAntimicrobial resistance in foodborne bacteria remains a public health concern in Europe
Antimicrobial resistance (AMR) in common foodborne bacteria such as Salmonella and Campylobacter continues to be a public health concern across Europe, according to a new joint report from EFSA and ECDC.

NewsComplexity key to preventing infection after heart surgery
Research indicates that uniform materials could be the culprit behind deadly infections that can occur when using synthetic materials for cardiovascular grafts.
-
NewsMacrophage immune cells need constant reminders to retain memories of prior infections
Researchers have discovered that immune cells known as macrophages remain poised to fight repeat infections due to the persistent presence of signaling molecules left behind during previous infections.

NewsMicrobes harvest metals from meteorites aboard space station
Microorganisms can harvest crucial minerals from rocks and could provide a sustainable alternative to transporting much-needed resources from Earth. Researchers have studied how those microorganisms extract platinum group elements from a meteorite in microgravity, with an experiment conducted aboard the International Space Station.
