NewsWhy feeling sick may be important for surviving infection
In a new perspective, scientists propose a different way of thinking about sickness symptoms: what if these behaviors are part of an integrated immune strategy that operates across scales — from individual cells to tissues and organs, to the whole organism — and helps promote survival?

NewsHantavirus cluster linked to cruise ship highlights ongoing zoonotic risk and the need for vigilance
Experts emphasized caution while underscoring the importance of environmental controls, early detection, and clear communication in travel settings.

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 uncover three families of ‘sponge’ proteins deployed by phages
Using an innovative research approach that combines artificial intelligence with experimental biology, researchers have uncovered new families of sponge proteins in phage genomes that disrupt immune communication in bacteria.

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.

NewsChanges in CDC communication undermine public trust in vaccines
Exposure to uncertainty-based messaging about vaccines increased perceived vaccine risks and uncertainty, reduced vaccination intentions, lowered trust in the CDC, and increased endorsement of science-denial strategies.

NewsCervical cancer: A growing gap between high- and low-income countries
While high-income countries could eliminate cervical cancer by 2048 through human papillomavirus (HPV) vaccination and screening, the gap with lower-income countries is widening.

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.

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.

NewsTeam discovers gene pattern that could help doctors identify Ebola faster and more accurately
Researchers have made an important discovery that could help doctors tell Ebola apart from other infections more quickly. The overlap of response by Ebola and other pathogens had made it difficult to find markers that are truly unique to Ebola.

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.

NewsHow the immune system battles lifelong viral infections acquired at birth
Millions of people worldwide carry viral infections they acquired at birth, often for life. For a long time it was assumed that the immune system hardly fights these pathogens. Researchers show that the body’s defenses do indeed act against the virus.

NewsSelf‑replicating circular RNA persists in extreme environments: Insights from hot spring microbiomes
Researchers who previously identified a highly unusual RNA virus in a high-temperature hot spring ecosystem searched for distinct types of self-replicating RNAs in a similar extreme environment, and a novel circular RNA replicon was identified within the microbial community inhabiting the hot spring.

NewsNew study suggests reduced newborn hepatitis B vaccination coverage may increase infant infections
Researchers found that lower vaccination coverage among infants born to unscreened mothers was associated with a substantial increase in HBV infections.
