NewsIntranasal herpes infection may produce neurobehavioral symptoms, study finds
A new study finds that herpes infection through the nose can lead to anxiety, motor impairment and cognitive issues. The research is the first to show that, by exploiting a cellular enzyme, the virus can produce behavioral symptoms.

NewsStudy discovers tuberculosis genes necessary for airborne transmission
Tuberculosis bacteria rely on a family of genes that help them survive the challenging journey from one person’s lungs to another person’s during coughing, sneezing or talking, according to a study that offers new targets for tuberculosis therapies.

NewsPrevalence of neutralizing antibodies to AAV2 and AAV9 in individuals with Niemann-Pick disease
A new study shows that more than half of individuals with Niemann-Pick disease, type C1 (NPC1) who were tested lacked neutralizing antibodies against either adeno-associated virus (AAV) 2 or AAV9.

NewsInhaled COVID vaccine study begins recruitment for phase-2 human trials
Researchers have started a phase-2 clinical trial on a next-generation, inhaled COVID-19 vaccine. Findings from the phase-1 trial indicate that the vaccine is more effective at inducing immune responses than traditional injected vaccines are.

NewsGenes combined with immune response to Epstein-Barr virus increase MS risk
In multiple sclerosis (MS), antibodies to the common Epstein-Barr virus can accidentally attack a protein in the brain and spinal cord. New research shows that the combination of certain viral antibodies and genetic risk factors can be linked to a greatly increased risk of MS.

NewsGreat whale pee funnel carries nutrients thousands of miles, boosting phytoplanktons
A new study shows that whales carry huge quantities of nutrients horizontally, across whole ocean basins, from rich, cold waters where they feed to warm shores near the equator where they mate and give birth.

NewsEarly-life gut microbes may protect against diabetes, research in mice suggests
A research discovered that the colonization of a fungus called <i>Candida dubliniensis</i> in the early life gut microbiome of mice, is able to promote growth of pancreatic beta cells in the presence of macrophages to restore blood insulin level and improve metabolic functions, thus reducing risks of type 1 diabetes.

NewsScientists develop low-cost handheld sensor test for airborne bird flu
Researchers have developed a prototype sensor that detects a virus that causes bird flu (H5N1) in air samples. The low-cost handheld sensor detects the virus at levels below an infectious dose and could lead to rapid aerosol testing for airborne avian influenza.
