NewsHow citrus rewires its vascular system to fight Huanglongbing
By profiling thousands of individual cells, researchers mapped how different vascular cell types in citrus roots respond during early stages of infection with Candidatus Liberibacter asiaticus, revealing profound changes in cell fate, gene expression, and tissue differentiation.

NewsSelf-repairing biohybrid system uses sunlight to purify uranium-contaminated water
The efficiency of microbial remediation technologies is often limited by the slow electron transfer rate of microorganisms themselves. Scientists have successfully constructed a novel, self-regenerating “bacteria-mineral” biohybrid system that can utilize light like a solar cell, greatly enhancing the purification efficiency of uranium pollution.

NewsNew study finds sex and menopause-based differences in presentation of early Lyme disease
In a new study, researchers found that male and female patients with early Lyme disease present with different signs of the disease in the symptoms they report, their physical exams and their laboratory test results.

NewsScientists find that silencing bacteria can worsen heart infections
By studying a bacterium responsible for a severe heart infection, the scientists show that disrupting bacterial communication can be associated with adverse clinical outcomes. These findings open the door to more targeted therapeutic strategies against this type of infection.

NewsResearchers engineer bacteria capable of consuming tumours from the inside out
A research team is developing a novel tool to treat cancer by engineering hungry bacteria to literally eat tumours from the inside out. They added a gene to the organism from a related bacterium that can better tolerate oxygen and found a way to activate the oxygen-resistant gene at just the right time.

NewsScientists unlock magnetic secrets of bacteria with built-in compass
Some bacteria are miniature masters of navigation: A built-in “compass” made of magnetic nanoparticles helps them to reliably find the optimal habitat. Researchers have now unlocked the magnetic properties of individual bacteria — an important step toward harnessing the potential for technology.

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.
