NewsSevere COVID-19 and flu facilitate lung cancer months or years later, new research shows
Severe COVID-19 and influenza infections prime the lungs for cancer and can accelerate the disease’s development, but vaccination heads off those harmful effects, new research indicates.

NewsSeaweed has the potential to create a shield to block norovirus infection
Seaweed has certain properties which have the ability to create a shield within the human body, effectively blocking norovirus infection. Fucoidan, from brown seaweed, showed the strongest and most consistent blocking activity against two major norovirus strains, GII.4 and GII.17.

NewsBuilding protection against infectious diseases with nanostructured vaccines
Researchers have leveraged a recently developed highly versatile DNA origami nanotechnology that is both vaccine and adjuvant, named DoriVac, as an alternative to current vaccine platforms.

NewsRecent pandemic viruses jumped to humans without prior adaptation, study finds
A large-scale evolutionary analysis shows most zoonotic viruses emerge without prior adaptation, while passing through a laboratory leaves detectable genetic signatures, offering a new tool to interpret outbreak origins.

NewsMpox immune test validated during Rwandan outbreak
An antibody test for the infectious disease Mpox was successfully developed during the new clade 1b outbreak in Rwanda, the first time that an assay of its kind has been validated within this setting.

NewsNew studies reveal how Clostridioides difficile behaves inside the body
Researchers studying C. diff at multiple levels, from how individual bacterial cells behave inside the gut to the molecular switches that help them survive and spread, are revealing hidden vulnerabilities.

NewsHerpes virus fluidizes cell nuclei to multiply faster
A new study finds that herpes simplex virus uses a protein called infected cell protein 4 (ICP4) to make the human nucleus more fluid-like, which in turn makes it easier for the virus to replicate itself. Blocking the ability of ICP4 to fluidize the nuclear compartment caused a drop in viral copy production.

NewsArtificial feeding platform transforms study of ticks and their diseases
The world’s first lab-based tick feeding system for bush ticks has transformed the study of ticks and how they transmit disease. The novel, host-free technology reduces the need for animal experiments in tick studies, facilitating more ethical, reproducible research.

NewsNew compound stops common complications after intestinal surgery
Researchers have synthesized and tested a new compound in mice that shows promise in protecting the liver from damage and improving nutrient absorption after small bowel resection. They also found that the drug works only on the gastrointestinal tract.

NewsNew study reveals how hygienic honey bees show unique advantages in fighting infectious pathogens in adult bees
For the first time, research shows that a key social trait in honey bees is linked to measurable physiological advantages that can improve colony survival. The study uncovers how hygienic honey bee colonies mount stronger individual immune defenses against Nosema ceranae.

NewsScientists identify more effective way to detect poultry viruses in live markets
Scientists have found that viruses circulating in live poultry markets can be detected more effectively by sampling the surrounding environment than by testing individual birds. The study shows that environmental sampling can uncover a broader range of poultry viruses.

NewsStudy warns of underrecognized Lassa Fever threat with global implications
A new study shows an urgent need for improved detection and treatment of Lassa fever. The study in Liberia found a high prevalence of Lassa fever among febrile admissions: 11% of patients with fever had Lassa fever despite not being suspected clinically.

NewsHow periodontitis-linked bacteria accelerate osteoporosis-like bone loss through the gut
Researchers reveal that salivary bacteria from gum disease alter gut metabolism, driving osteoclast activity and systemic bone loss. They analyzed salivary microbiota from individuals with advanced periodontitis and compared them with samples from periodontally healthy donors.
-
NewsResearchers identify ‘neuroimmune signature’ that can predict viral hepatitis complications
A network of genes linked to the nervous and immune systems can predict cancer risk and even explain symptoms such as fatigue and depression resulting from viral hepatitis infection.
-
NewsScientists develop shape-shifting scaffold that fights infection and rebuilds bone
Scientists have developed a body-temperature–responsive, 3D-printed shape-memory scaffold coated with a metal–polyphenol network to treat infectious bone defects. It is designed to adapt to irregular bone defects while providing antibacterial activity, immune regulation, and osteogenic support.

News Thermo Fisher Scientific launches new color-based culture media to help detect Candida infections faster
Thermo Fisher Scientific today announced the launch of Thermo Scientific™ Brilliance™ Candida 2 Agar and Spectra™ Candida Agar, new color-based (chromogenic) culture media to help laboratories quickly detect and differentiate clinically important Candida species.

NewsStudy finds natural fungal supplement improves COVID-19 vaccine response
Researchers have found that a natural fungal supplement taken at the time of COVID-19 vaccination reduced short-term vaccine side effects and helped antibodies last longer in people who had not previously been exposed to the virus.
-
NewsNew tool reveals the secrets of HIV-infected cells
Scientists have developed a novel tool—named HIV-seq—for profiling the features of rare HIV-infected cells from people with HIV. Using the new tool, they’ve found key differences in people’s HIV-infected cells before versus after starting antiretroviral therapy.

NewsEditing for timing, not overdrive: A new genetic route to fire blight resistance in apple
Fire blight remains one of the most destructive bacterial diseases threatening global apple production. A new study identifies a family of inducible lectin genes, MdAGGs, as critical components of apple immune defense and demonstrates that their precise activation timing is key to effective resistance.

NewsNanoparticle vaccine approach takes on a new target: Hepatitis C virus
Scientists have engineered a native-like, stabilized version of Hepatitis C virus’s E1E2 complex and used it to build a nanoparticle-based vaccine candidate. It uses a technology called self-assembling protein nanoparticles, which organizes copies of the proteins into virus-like clusters that the immune system can recognize.
