A federally funded project analyzing temperature, light pollution, and bird and mosquito abundance aims to pin down how these and other factors affect West Nile virus transmission. The ultimate goal is to advise health departments of the best time of year to kill mosquitoes that transmit the virus.
A research team at Indiana University Bloomington has uncovered new details about how a tiny virus builds its protective outer shell —a crucial part of its ability to infect cells.
The increase of microbes resistant to antibiotics is a growing problem. These include, for example, Neisseria gonorrhoeae, a bacterium which causes gonorrhea. Researchers from the universities in Konstanz and Vienna discover a new class of antibiotic that selectively targets Neisseria gonorrhoeae. These substances trigger a self-destruction program, which also operates in multi-resistant variants of the pathogen. This type of treatment could be used in an adapted form against other pathogens, so the scientists have made a real breakthrough in the fight against superbugs. The results have been published in the renowned journal Nature Microbiology.
FAU researchers have been awarded a five-year NIH grant to address the urgent need for a reliable, rapid and affordable self-test for early HIV detection. Expected to cost less than $5, the novel micro-chip technology will detect HIV during the acute infection phase or viral rebound, deliver rapid results in about 40 minutes and remain stable without refrigeration.
Malaria, responsible for hundreds of thousands of deaths each year worldwide, is caused by a parasite transmitted through the salivary glands of female Anopheles mosquitoes. Understanding the biology of these tissues is critical to developing new treatments for the disease, found mostly in tropical countries.
Visby Medical Receives Landmark FDA De Novo Authorization for First-Ever OTC PCR Test for Sexual Health
Two researchers from the Johns Hopkins University School of Medicine have been elected 2024 Fellows of the American Association for the Advancement of Science (AAAS), the largest scientific society in the world and publisher of the Science family of journals.
A powerful AI model called Deep Novel Mutation Search (DNMS) predicts virus mutations more accurately and efficiently than traditional, time-consuming lab experiments. Focused on the SARS-CoV-2 spike protein, the model uses a specialized protein language model fine-tuned to understand the virus's specific “language.” DNMS can predict mutations that cause small, functional changes – crucial for viruses like SARS-CoV-2, which evolve through subtle adjustments to maintain function.
COVID infection has been linked to higher risk of autoimmune disorders, including rheumatoid arthritis and type 1 diabetes. Scientists used advanced data analysis and machine learning to identify viral proteins that are more likely to trigger autoimmunity.
Measles is a highly contagious viral infection that can cause serious health problems. The good news: Two doses of the vaccine developed in the 1960s are 97% effective in protecting you from getting infected, and that protection lasts a lifetime.
A small molecule shaped like a lasso may be a powerful tool in the fight against infectious diseases, according to a new study in Nature co-authored by University of Illinois Chicago researchers.
"Our ultimate goal is to develop vaccines against these very difficult viruses. Understanding how these viruses manipulate the immune response can help guide the development of the best vaccine approach."
The latest CIPHER research on H5N1 viral lineages could have major implications for vaccine development.
”TB anywhere is TB everywhere,” said tuberculosis expert Philip Hopewell, MD, in the latest ATS Breathe Easy podcast. The U.S. has one of the lowest incidence rates of TB in the world, yet in January, an outbreak caused 2 deaths, and 67 persons developed latent TB in Kansas, which set off alarm bells in public health.

A team of experts from McMaster University has led the creation of Canada’s first-ever comprehensive guidelines for diagnosing, managing, preventing, and treating post COVID-19 condition (PCC), more commonly known as long COVID.
As of early 2025, tuberculosis cases are increasing in the U.S. This disease, often shortened to TB, causes significant lung damage and, if not treated, is almost always lethal. World TB Day on March 24 raises awareness about the disease and commemorates Robert Koch’s discovery of the source bacterium Mycobacterium tuberculosis. More than a century later, scientists continue refining TB diagnosis methods and treatment strategies , some of which are in these four ACS journal articles.
Johns Hopkins Medicine scientists say they have shed new light on how bacteria protect themselves from certain phage invaders — by seizing genetic material from weakened, dormant phages and using it to “vaccinate” themselves to elicit an immune response.
