Sparking new dogs versus cats arguments, a study is suggesting exposure to a pet dog over a child’s first years can be linked to a lower risk of developing schizophrenia as an adult. The same correlation was not seen in children raised with cats.

In a first for the US, Johns Hopkins University is launching a research center dedicated to investigating psychedelic compounds.

A massive umbrella study, encompassing 277 clinical trials, into the effects of nutritional supplements and dietary interventions has concluded almost all vitamin and mineral supplements play no role in protecting from cardiovascular disease, or extending one’s lifespan.

A rigorous animal study has demonstrated how the misfolded proteins thought to cause Parkinson’s disease may originate in the gut, and travel up to the brain via the vagus nerve. This research builds on evidence pointing to a gut-brain connection in the disease and hints at new treatment pathways.

Research has revealed some cases of schizophrenia can be associated with abnormal protein buildup in the brain similar to that seen in neurodegenerative disorders like Alzheimer's. It's hoped the discovery will lead to better diagnostic strategies identifying specific types of schizophrenia.

A new study, led by researchers from the Johns Hopkins University School of Medicine, has described the discovery of a new kind of immune cell that is hypothesized to play a fundamental role in the development of type 1 diabetes.

New research from Johns Hopkins University has identified a variety of biomarkers that can be used to predict the onset of Alzheimer’s years before symptoms appear. The study presents nine measures that can signal the onset of the disease up to 30 years before cognitive decline becomes apparent.

Essential oils are most commonly associated with aromatherapy and other alternative “medicines." Now a team at Johns Hopkins has found that some essential oils may have antibiotic properties, particularly against a persisting form of the bacteria that causes Lyme disease.

Using a new experimental drug​, researchers at Johns Hopkins have ​​successfully reversed baldness, hair whitening and skin inflammation caused by high-fat diets in mice. It's hoped the research could lead to treatments to reverse baldness and speed wound healing.

Surgeons at Johns Hopkins University have carried out the first ever complete transplant of a penis and scrotum. The procedure is being hailed as a success, with the recipient now on the mend and the team optimistic that he will regain close to regular function of his genitalia.

A new blood test designed to detect eight common types of cancer is showing excitingly positive results in early trials. Developed by a team led by researchers at Johns Hopkins Kimmel Cancer Center, the test tracks two different types of biomarkers that can signal the presence of the disease.

​A team of scientists have set a rather unique record – they've used a fixed-wing drone to fly medical samples farther than any drone has ever done before. The aircraft transported human blood samples across 161 miles (259 km) of Arizona desert.
