A new study in the European Heart Journal shows the shingles vaccine may protect heart health. Researchers found vaccinated adults had a 23% lower risk of cardiovascular events.
The vaccine lowered the risk of stroke, heart failure, and coronary heart disease. The study tracked over 1.2 million people aged 50 and older in South Korea.
Climate change is warming weather and driving insect populations into new territories. Areas like North America and Europe can expect to see more infections from insect bites.
Mosquitoes and ticks can spread multiple harmful illnesses through bites, including Lyme disease, malaria, dengue, anaplasmosis, babesiosis, and West Nile virus. These illnesses can cause lasting health problems if not treated early.
Fortunately, new research from Acadia University may provide improved protection from tick bites. The Acadia researchers discovered that lemongrass essential oil can block a tick’s ability to detect humans.
The discovery could lead to more effective, natural alternatives to synthetic repellents like DEET. While DEET is widely used, it carries potential risks for skin irritation and environmental harm.
Lemongrass oil, by contrast, is both natural and environmentally friendly. The oil appears to mask human scent and confuse ticks’ sense of smell.
A new vaccine offers strong promise against H5N1 bird flu. The clade 2.3.4.4b virus has spread across North America. Bird flu threatens livestock, birds, and human health. New mutations raise serious pandemic concerns.
Researchers developed a nanoparticle vaccine using viral surface proteins. H5 and N1 proteins were displayed on immunogenic liposomes. These proteins help trigger a strong immune response in the body.
Mice received the vaccine and produced antibodies targeting both proteins. All vaccinated mice survived a deadly H5N1 infection. These results suggest the vaccine offers complete protection.
Climate change is helping dangerous diseases spread across the Arctic. Scientists say rising temperatures are melting permafrost and damaging ecosystems. These changes open new paths for infections to move from animals to people.
An international research team published the findings in Science of the Total Environment. The study shows how warming is reshaping Arctic life. New roads, industries, and people now reach once-isolated areas. This raises the risk of infections like brucellosis, tularemia, and E. coli.
Gepotidacin, a new antibiotic pill, works as well as standard treatments for gonorrhea. These results appeared in a large, recent study published in The Lancet. The new drug could offer a simple oral option for treating this common sexually transmitted infection.
