NewsScientist awarded $500,000 Gruber Genetics Prize for pioneering discoveries in bacterial immune systems
The 2025 Gruber Genetics Prize is being awarded to geneticist and molecular biologist Rotem Sorek, Ph.D., of the Weizmann Institute of Science, for his discoveries in the immune system of bacteria.

NewsResearchers reveal lipid-based communication between body and gut microbes
A new study shows how a host protein can specifically recognize bacterial lipids, thus triggering beneficial immune responses. It also highlights a new way the body actively shapes the gut microbiome by communicating with microbes to maintain balance.

News‘Loop’hole: HIV-1 hijacks human immune cells using circular RNAs
In a groundbreaking discovery, researchers have identified a never-before-seen mechanism that enables the human immunodeficiency type 1 virus (HIV-1) to evade the body’s natural defenses and use it to support its survival and replication.

NewsScientists reveal key bacterial immune mechanism
Researchers have uncovered a pivotal mechanism by which bacteria defend themselves against viral infection. Cyclic dinucleotides (CDNs), synthesized during activation of the cyclic oligonucleotide-based anti-phage signaling system (CBASS) immune mechanism, trigger the filamentous assembly of phospholipase effectors, which execute the downstream immune response.

NewsNew study offers insights into designing safe, effective nasal vaccines
Researchers found that nasal vaccine boosters can trigger strong immune defenses in the respiratory tract, even without the help of immune-boosting ingredients known as adjuvants. The findings, researchers suggest, may offer critical insights into developing safer, more effective nasal vaccines in the future.

NewsNew discovery explains why men are more affected by severe COVID-19
Researchers have found another piece of the puzzle that explains why there are differences in immune responses in women and men when they get sick with COVID-19. This discovery has implications for treatment strategies for severe COVID-19.

NewsNew vaccine protects against swine, human and bird flu
Annual flu shots could become a thing of the past under a new vaccine strategy. A new study describes a vaccine that protects against H1N1 swine flu and can also protect against influenza in humans and birds.

NewsCOVID-19 caused by the Omicron variant in lung transplant recipients: a single center case series
A new study investigates the risk factors for developing severe disease in lung transplant patients as a result of the Omicron variant of Covid-19.

NewsHeart rhythm disorder traced to bacterium lurking in our gums
A new study finds that a gum disease bacterium can slip into the bloodstream and infiltrate the heart. There, it drives scar tissue buildup—known as fibrosis—distorting the heart’s architecture, interfering with electrical signals, and raising the risk of atrial fibrillation (AFib).

NewsResearchers reveal how fungi ‘manipulate’ the course of tumors
In pancreatic ductal adenocarcinoma (PDA), the abnormal colonization of fungal communities has become a research hotspot. New research indicates that Malassezia is not only a ’marker’ in the tumor microenvironment but also a potential driver of cancer development.

NewsForever chemicals influence cellular immune response to coronavirus
A new study shows that PFAS influence the cellular immune response to coronavirus and also reveals sex-specific differences as to how the immune system reacts to the virus.

NewsPredictive AI model can help build vaccines for future versions of a virus
Researchers have created an AI tool called EVE-Vax that can predict and design viral proteins likely to emerge in the future. For SARS-CoV-2, panels of these “designer” proteins triggered similar immune responses as real-life viral proteins that emerged during the pandemic.

NewsScientists engineer antibody against flu with sticky staying power
Scientists have engineered a monoclonal antibody that can protect mice from a lethal dose of influenza A, a new study shows. The new molecule combines the specificity of a mature flu fighter with the broad binding capacity of a more general immune system defender. Source: NIAID Colorized transmission ...

NewsViruses under the super microscope: How influenza viruses communicate with cells
Scientists have characterized a new model of influenza A infection: binding to MHC class II complexes as an alternative receptor and the associated dynamic reorganization of the cell surface.

NewsSilver nanoparticles produced by fungus could be used to prevent and treat COVID-19
Silver nanoparticles produced by the fungus Trichoderma reesei could become important allies in the prevention and treatment of COVID-19. Tests on hamsters showed that they not only inhibited the infection but also reduced the viral load in the lungs.

NewsLong COVID may cause long-term changes in the heart and lungs and may lead to cardiac and pulmonary diseases
Patients suffering from long COVID may exhibit persistent inflammation in the heart and lungs for up to a year following SARS-CoV-2 infection, potentially placing them at elevated risk for future cardiac and pulmonary conditions.
-
NewsClinical trial underway for potential Long COVID treatment
A clinical trial is underway to assess the effectiveness and safety of sipavibart, AstraZeneca’s long-acting monoclonal antibody designed to provide protection against Covid-19, as a potential treatment for Long Covid.

NewsScientists launch intranasal albumin-based vaccine technology platform against respiratory virus
A new paper reports on a novel vaccine technology platform, in which the subunit antigen is genetically fused to albumin. The albumin-antigen fusion vaccines induced both systemic and mucosal antigen-specific antibody responses.

NewsAntibodies that recognize lipids: A new path for HIV vaccines and autoimmune disease treatments
Scientists have used computer modeling to illustrate how a specific class of antibodies actually use lipids to recognize the HIV virus. The work highlights antibody features that could help people design better vaccines for HIV and autoimmune diseases.

NewsScientists uncover the link between ‘good’ gut bacteria and rheumatoid arthritis
After spending years tracing the origin and migration pattern of an unusual type of immune cell in mice, researchers have shown how activity of “good” microbes in the gut is linked to rheumatoid arthritis and, potentially, other autoimmune diseases.
