NewsEvolving antibiotic resistance under pressure may lead to personalized treatment
A new study demonstrates the use of an experimental evolution approach to map genetic mutations in Acinetobacter baumannii treated with one of two uncommon antibiotics.

NewsLow-dose cannabis compound reduces side effects of HIV treatment
Long-term, low doses of THC mitigate many harmful side effects and inflammation caused by HIV and antiretroviral therapy (ART). Benefits included increased production of serotonin, while inflammation, cholesterol and harmful secondary bile acids were all reduced.

News Sea stars show surprising resilience after disease outbreak
A decade after sea star wasting disease devastated ochre sea star populations along the U.S. West Coast, new research suggests that the epidemic shifted populations from a stable, adult-dominated state to one marked by fluctuations in sea star sizes and ages.

NewsThe ‘MDME Axis’: A new view on how microbial metabolites epigenetically shape host health
A review introduces the ’MDME Axis’, a new framework explaining how metabolites from the gut microbiome epigenetically reprogram our genes, influencing host health and disease.
-
NewsResearchers discover novel phage DNA modifications that offer new hope against antibiotic-resistant superbugs
A groundbreaking discovery reveals a unique way phages modify their DNA with arabinose sugars to protect themselves from bacterial defence systems. Natural DNA phage modifications occur at a higher rate than previously predicted, the study revealed.

NewsMicrobiome around Xanthomonas infection in tomato plants signposts scientists to the bacterium of its downfall
Scientists have uncovered a bacterium in the microbiome of tomato leaves that can be used to fight back against infection by Xanthomonas, a disease that poses a major challenge to tomato growers worldwide.

NewsTemporary benefit for immune system in early HIV treatment, but dysregulation returns
A study investigated whether immune dysregulation can be prevented by starting HIV medication immediately after infection. Six months after this early treatment, the immune system did indeed work as in people without HIV, but in the longer term, the immune system was disrupted again.

NewsThe fart factor: researchers get wind of hydrogen’s role in the gut
Scientists have revealed how hydrogen is made and used in the human gut. Though infamous for making farts ignite, hydrogen also has a positive role supporting gut health.

NewsNew study links gut microbes to common heart disease - suggesting ‘Jekyll and Hyde’ action
Researchers studying gut microbes recently identified 15 bacterial species associated with coronary artery disease. The analysis reveals multiple pathways linked to disease severity, including increased inflammation and metabolic imbalance.

NewsCOVID-19 vaccination linked to reduced infections in children with eczema
Children with atopic dermatitis (AD), commonly known as eczema, may experience fewer infections and allergic complications if they receive the COVID-19 vaccine, according to new research.
-
NewsUrban fungi are showing signs of thermal adaptation
A new study finds that common fungal species may be adapting to higher temperatures in warmer sites within cities compared to cooler sites in the same city. The findings could signify that urban fungi could one day evolve into disease-causing pathogens.
-
NewsScientists unlock how viruses punch above their weight
A news study reveals how rabies virus manipulates so many cellular processes despite being armed with only a few proteins. Researchers believe other dangerous viruses like Nipah and Ebola may also work the same way.

NewsUpwelling promotes N-fixing symbiont of Sargassum algae - giving it an edge
An international research team has uncovered the main mechanism behind the algae blooms of the Great Atlantic Sargassum Belt. Identification of the climatic conditions that facilitate this phenomenon allows them to predict future stranding events of Sargassum.

NewsScientists uncover tuberculosis bacterium’s ’heartbeat’, opening door to new treatments
Scientists have identified a molecular system inside Mycobacterium tuberculosis that functions like the organism’s heart or lungs, keeping it alive. The system, known as PrrAB, helps the bacterium generate energy and breathe. When researchers used a gene-silencing tool, the bacterium died.
-
NewsTwo amino acids help plants decide whether to welcome or repel nitrogen-fixing bacteria
Researchers are one step closer to understanding how some plants survive without nitrogen - a breakthrough that could eventually reduce the need for artificial fertilizer in crops such as wheat, maize, or rice.
-
NewsAncient viral DNA shapes modern human placentas
Researchers have uncovered how ancient viral DNA controls a gene linked to placenta development and pre-eclampsia, a life-threatening pregnancy disorder. The research could help identify pre-eclampsia risk much earlier.
-
NewsNot just a common cold: studies show RSV’s severity and impact on long-term health
Often confused for a common cold, respiratory syncytial virus (RSV) can in fact be serious and should be studied more closely. Researchers found that the illness could be of comparable severity to other more well-known respiratory viral infections (RVIs) – such as influenza and COVID-19.
-
NewsEarly-stage clinical trial demonstrates promise of intranasal influenza vaccine in generating broad immunity
Researchers report encouraging results from an early phase clinical trial that found an experimental intranasal vaccine triggered a broad immune response against multiple strains of H5N1 ’bird flu’, highlighting the potential of mucosal immunization strategies.
-
NewsAI can speed antibody design to thwart novel viruses: study
Artificial intelligence (AI) and “protein language” models can speed the design of monoclonal antibodies that prevent or reduce the severity of potentially life-threatening viral infections, according to a multi-institutional study

NewsNew study finds targets for a new tuberculosis vaccine
A large-scale screen of tuberculosis proteins has revealed several possible antigens that could be developed as a new vaccine for TB, the world’s deadliest infectious disease.
