NewsGut microbes actively support immunity in people living with HIV
A new study shows that gut microbes help bolster immunity in people living with HIV – and that, one day, these microbes may be harnessed to protect this population from infections driven by immune deficiency.

NewsResearchers identify natural compound that disarms drug-resistant bacteria
Scientists studying MRSA discovered that geranylgeranoic acid (GGA) – a naturally occurring fatty acid found in plants like ginger and turmeric – interferes with the bacteria’s virulence, its ability to infect, spread, defend itself, and cause disease.

NewsMalaria’s mRNA: Messages that mess with the immune system
A new study uncovers the malaria parasite’s RNA strategies – mechanisms that could inspire unexpected applications for RNA-based tools in multiple areas of medicine.

NewsStudy finds four of the CDC’s seven measles elimination status indicators missed
After public health experts declared measles eliminated in the U.S. in 2000, the U.S. CDC established seven indicators of measles elimination status to ensure that the country remained on track. Now researchers find that the U.S. missed four of the seven criteria, with the others at risk.

NewsIn mice, viruses gain virulence in some individuals, depending on genetics and sex
New research demonstrates that some hosts appear to serve as “evolutionary accelerators” that could enable viruses to gain virulence more quickly.

NewsStudy identifies multiple viruses and variants simultaneously by controlling the “speed” of CRISPR gene scissors
Scientists have developed a new diagnostic technology that simultaneously identifies various viruses and variants by controlling the “speed” of gene scissors.

NewsWhy antibiotics may soon fail to curb the plague bacterium - and where we can find new strategies
A new review shows that while most infections caused by the Yersinia plague bacterium can currently be treated with antibiotics, concerns about rising antimicrobial resistance mean that we need to come up with new ways to disarm the bacteria instead of killing them.

NewsStudy confirms effectiveness of medicinal plant against SARS-CoV-2 virus
A study has revealed that galloylquinic acids extracted from the leaves of Copaifera lucens Dwyer, a tree endemic to Brazil primarily found in the Atlantic Forest, have a multi-targeted effect against SARS-CoV-2, the virus that causes COVID-19.

NewsPet cats that roam outdoors carry similar disease risk as feral cats, global study finds
A new study has found that pet cats allowed to roam outside unsupervised carry infectious diseases at rates comparable to feral cats, even when they receive veterinary care, regular meals and shelter.

NewsSouth American camelids: Potential carriers of the zoonotic pathogen Campylobacter
A comprehensive investigation has identified a previously underappreciated source of thermotolerant Campylobacter spp. in South American camelids (SACs)—alpacas and llamas kept in Germany. The findings underscore the importance of expanding epidemiological surveillance beyond traditional livestock.

NewsSignificant rise in valley fever cases in El Paso linked to extreme weather and dust
A new study has identified a significant rise in Valley fever cases in El Paso over the past decade and found strong connections between the disease and extreme weather, wind and airborne dust.

NewsYour nose is a battlefield
Scientists have discovered that FluMist can trigger an immune response directly in nasal tissue in adults. The vaccine trains immune cells in the upper nasal passages to recognize and fight influenza virus infection. This immune response stays in the upper airways and can’t be detected via blood samples.

NewsHow does oligochitosan induce plant resistance against potato virus Y?
Plant immune inducers are crucial tools for the green management of crop diseases. As an environmentally friendly biological inducer, oligochitosan (COS) can activate plant defense mechanisms to resist pathogens such as fungi, bacteria, and viruses.

NewsNew study shows antibodies need a strong core — not just grip — to fight SARS-CoV-2
Researchers used advanced computer simulations to investigate how antibody–virus complexes respond to mechanical forces across multiple SARS-CoV-2 variants, including the original 2019 strain and Omicron subvariants BA.4 and JN.1.

NewsVaccine strategy induces broadly neutralising HIV antibodies
Researchers have developed a new vaccine strategy that has generated antibodies capable of neutralising highly divergent HIV variants. The study provides new insights into how the immune system can be guided towards a particularly protected part of the virus.

NewsResearch gaps and regional disparities revealed in global Lassa virus research landscape
A comprehensive bibliometric analysis spanning 55 years of Lassa virus (LASV) research has uncovered significant disparities in scientific output between high-income and endemic countries, while revealing a persistent shortage of studies addressing environmental factors influencing viral spread.

NewsNew study suggests seasonal flu vaccines may reduce severity of H5N1 bird flu infections
Researchers have found that seasonal influenza vaccines in routine global use may significantly reduce the risk of death from H5N1 infection. The findings that readily available tools may offer protection while the world races to develop more targeted solutions.

NewsThe handbook that can prepare countries for the next pandemic
A new handbook has been published to pave the way for better decision-making and greater preparedness for the next pandemic. It provides practical guidance on how mathematical models can be used to inform decision-making, and how the results can be communicated in times of crisis.

NewsTracking a persistent threat: How antibiotic-resistant bacteria travel from poultry farms to fresh produce
A new study develops an integrated quantitative microbial risk assessment (QMRA) model to trace the pathway of ESBL-producing E. coli from broiler farms to lettuce consumption, quantifying human health risks and identifying effective intervention strategies.

NewsPlasmodium uses its own PI3K to suppress eat-me signal and evade host immune clearance
A study finds that Plasmodium PI3K actively suppresses the externalization of phosphatidylserine on the surface of infected erythrocytes. When the activity of parasite PI3K was chemically inhibited or genetically disrupted, phosphatidylserine exposure on infected red blood cells increased markedly.
