NewsStudy uncovers first evidence of resistance to standard malaria treatment in African children with severe malaria
Researchers have uncovered evidence of partial resistance to artemisinin derivatives — the primary treatment for malaria — in young children with severe, or ’complicated’ malaria.

NewsNew study shows how salmonella tricks gut defenses to cause infection
A new study has uncovered how Salmonella bacteria, a major cause of food poisoning, can invade the gut even when protective bacteria are present.

NewsNew roles in infectious process for molecule that inhibits flu
Researchers have identified new roles for a protein long known to protect against severe flu infection – among them, raising the minimum number of viral particles needed to cause sickness.

NewsRule-breaking tuberculosis bacteria challenge growth norms
The rod-shaped tuberculosis (TB) bacterium is the first single-celled organism ever observed to maintain a consistent growth rate throughout its life cycle, a new study reports, hinting at why the pathogen so readily outmaneuvers our immune system and antibiotics.

NewsZinc deficiency promotes Acinetobacter lung infection: study
Dietary zinc deficiency promotes lung infection by Acinetobacter baumannii bacteria — a leading cause of ventilator-associated pneumonia, according to a new study.

NewsNew evidence links gut microbiome to chronic disease outcomes
A new review consolidates recent findings that demonstrate a causal role for the gut microbiome in the progression of multiple diseases, ranging from gastrointestinal conditions to immune-related and psychiatric disorders.

NewsStudy links high-risk Epstein-Barr virus lineage to nasopharyngeal cancer in southern China
Researchers have discovered a significant association between specific Epstein-Barr virus (EBV) variants and nasopharyngeal carcinoma (NPC), a cancer prevalent in southern China, where it is 20 times more common than in non-endemic regions of the world.

NewsMigrating birds have stowaway passengers: invasive ticks could spread novel diseases around the world
Ticks have always travelled on migrating birds — but the rising temperatures of the climate crisis mean they may now survive at their destination, and so could the pathogens they carry.

NewsClimate change responsible for 19% of today’s rising dengue burden - but Wolbachia offers hope
Climate change is having a massive global impact on dengue transmission, accounting for 19% of the current dengue burden, with a potential to spark an additional 40%-60% spike by 2050 — and by as much as 150%-200% in some areas.

NewsResearchers uncover Achilles heel of antibiotic-resistant bacteria
Scietnists have found that antibiotic resistance comes at a cost. While antibiotic resistance provides some advantages for the bacteria to survive, the team discovered that it’s also linked with a physiological limitation that hinders potential dominance.

NewsHow do microbiomes influence the study of life?
Researchers from the awardwinning One Health Microbiome Center reveal how holobiont biology underpins a holistic understanding of how life’s forms and functions, from human disease to agricultural output, depend upon the relationships between microbes and hosts.

NewsNew technique reveals the living microbes in Earth’s driest desert
An international team of researchers describes a new way to separate extracellular from intracellular genetic material, providing better insights into microbial life in low-biomass environments such as the Atacama Desert.

NewsClimate change threatens key ocean plankton groups
Planktonic foraminifera species may face unprecedented environmental conditions by the end of this century, potentially surpassing their survival thresholds, with extinctions impacting marine ecosystems and the ocean’s carbon storage capacity.

NewsChildren’s gut bacteria - and a superfood grain - may hold the key to diarrhea treatment
Diarrhea claims the lives of 500,000 children a year in low- and middle-income countries. Now researchers have linked chronic diarrhea to a specific pattern of gut bacteria, a discovery that could pave the way for new treatments.

NewsStudy identifies ‘Achilles heel’ of drug-resistant pathogens
A study has found a highly vulnerable weakness in drug-resistant Mycobacterium tuberculosis, using a genetic platform to identify biological pathways in a drug-resistant strain of the bacterium that are highly sensitive to inhibition.

NewsKey influenza-severity risk factor found hiding in plain sight on our antibodies
Viruses are the fastest-evolving biological entity on earth. This fact explains why we need flu shots every year: Seasonal influenza perennially outwits the immunity we’ve acquired from previous vaccinations or infections. Source: Yuki999 H1N1 virus Some new strains are rougher than others. The 1918 flu pandemic killed ...
