When someone has suffered a stroke, it's imperative that they receive medical attention as soon as possible. And while current diagnostic procedures take some time, an experimental smartphone app could deliver results much quicker.

We are seeing some exciting research advances that could help reveal Parkinson's in its ealy stages. Scientists have now produced another by demonstrating how a skin biopsy can be used to identify the disease with a high degree of accuracy.

A new study claims to explain the association between gum disease and diabetes, cardiovascular disease and even Alzheimer’s. The research demonstrates how periodontitis can initiate a systemic immune response that spreads throughout the entire body.

Chemotherapy remains one of our best treatments against cancer but, frustratingly, cancer cells can develop resistance to these drugs. Now, researchers have found that calcium can weaken their defense mechanism, making drugs effective once more.

A team of researchers has made a surprising new discovery, finding a pair of previously unknown salivary glands. Nestled deep in the back of the nasopharynx, the discovery may help prevent damaging side effects from head and neck cancer radiotherapy.

Fat is best known for being an energy storage system, but it may also play a previously-unknown role in defense against infection. Scientists from the Universities of Queensland and Barcelona have found that cells can use fats to fight off bacteria.

Researchers in India have taken an impressive step forward with efforts to tackle cancer using magnetic nanoparticles, working the technology into a bandage that proved capable of killing skin cancer cells in experiments on mice.

Researchers have developed a new tool that could help form more effective brain cancer treatments, with an ability to classify the deadliest cells to help gauge how aggressive a patient’s disease might be.

Antibiotic-resistant bacteria are poised to become a huge health problem, and we desperately need new treatments. Now, researchers have engineered new antimicrobial molecules from wasp venom, which have shown promise in tests in mice.

Dopamine and serotonin are brain chemicals implicated in a range of neurological disorders including Parkinson’s and depression. A new tool is offering an unprecedented look at these neurotransmitters in action.

Tinnitus is an aggravating disorder, causing sufferers to constantly hear a ringing in their ears. A new system could help, though, by simultaneously zapping their tongue and delivering sounds to their ears.

A research group at the University of Iowa has built what is described as a "remote control" for diabetes management that uses electromagnetic fields (EMFs) to reduce blood sugar levels and improve the body’s response to insulin.
