River blindness and elephantiasis are debilitating diseases caused by parasitic worms that infect as many as 150 million people worldwide. They are among the "neglected tropical diseases" for which better treatments are desperately needed. But they were far from the mind of cell biologist William Sullivan when he began studying the microbial parasite Wolbachia, best known for its extraordinary effects on the many insect species it infects.

The common but dangerous heart rhythm disorder known as atrial fibrillation—or a-fib—can go undetected for years. Now, research suggests a high-tech, wearable patch might spot the condition early. The study was published in the Journal of the American Medical Association.
HIV-positive children in South Africa are more likely to have developmental disabilities compared to children who are HIV negative, according to researchers at Columbia University's Mailman School of Public Health.
HIV-positive children ages 4 to 6 had nearly four times the odds of delays in sitting, standing, walking, and speaking, and more than twice the odds of a hearing disability and cognitive delay compared to HIV-negative children. The findings are published online in the journal PLOS ONE.
The current whooping cough vaccine was universally adopted in the US in 1996 to replace the original vaccine based on killed Bordetella pertussis because of a stronger safety profile. The new formulation was found to be effective in preventing whooping cough during vulnerable stages in the lifespan but the kind of pertussis vaccine used to prime the immune system leaves a lasting impression.
In their latest study, researchers at La Jolla Institute for Allergy and Immunology (LJI) report that individuals who had been inoculated with the newer vaccine as part of their initial series of shots mount a weaker recall response when receiving booster shots later on.
In an article published recently in the journal Nature Communications, researchers affiliated with the University of São Paulo (USP) in Brazil describe the central role played by an enzyme called phosphatidylinositol 3-kinase gamma (PI3Kγ) in regulating the immune response against Trypanosoma cruzi, the protozoan parasite that causes Chagas disease.
In 2015, a New Delhi –metallo-beta-lactamase (NDM) Escherichia coli bacteria was discovered in two Finnish dogs. An article recently published in the journal Eurosurveillance reveals that the dogs' owner did also carry the bacterium. This is presumably the first time in the world that the transmission of NDM-bacteria between a dog and a human has been reported.
Colombo, Sri Lanka has announced that it is moving its centuries-old folk medicine system for protection under the international intellectual property system.
Health insurance has come to be the buzzword in India's policy discourse ever since the Union government announced the National Health Protection Scheme (NHPS).
In the eastern US, risk of contracting Lyme disease is higher in fragmented forests with high rodent densities and low numbers of resident fox, opossum, and raccoons. These are among the findings from an analysis of 19 years of data on the ecology of tick-borne disease in a forested landscape, recently published in the journal Ecology.
Mutations in a gene involved in steroid signaling likely contribute to preterm birth, report Johanna Huusko of the University of Oulu and Cincinnati Children's Hospital Medical Center and colleagues, in a study of European women who had experienced at least one early delivery
Systemic lupus erythematosus (SLE) is a chronic disease that causes inflammation and tissue damage. SLE can involve many organs and systems and has a poor prognosis. It is one of a large group of autoimmune disorders, which occur when the immune system attacks the body's own tissues and organs
