American scientists have developed a smartphone app that can identify types of bacteria in one hour, down from a typical turnaround of 18 to 28 hours. The reduced detection time should mean faster diagnosis, treatment and recovery for patients, as well as reduced costs.

A small, but promising, new study suggests there is a link between a thinning of the retina and the onset of Parkinson’s disease, pointing toward a potential simple eye exam that may help diagnose the disease before major symptoms appear.

A fascinating cancer detection technique has been developed by scientists at Stanford University. The process involves a small magnetic wire being inserted into a vein where it attracts free-floating tumor cells in the blood.

Last year an impressive study suggested a reliable set of blood biomarkers has been isolated that could successfully diagnose Autism Spectrum Disorder in children. Now a follow-up study has verified those results pointing towards further clinical trials and potentially a commercially available test.

A new study is suggesting that a simple at-home test, administered through a laptop or smartphone, could accurately diagnose cases of mild cognitive impairment, allowing for early interventions to help prevent further cognitive decline.

Mild to moderate asthma can be difficult to diagnose, as its symptoms change over time and are often affected by other respiratory conditions. A new test, however, is able to definitively determine whether or not a patient has asthma – via just a swabbing of the nose.

Diagnosing symptomatic carriers of malaria is difficult enough, needing careful examination of blood samples, but picking up asymptomatic carriers is even more challenging. A team set out to find a way to diagnose those asymptomatic malaria carriers and the key turned out to be in body odor.

Mammograms can miss harmful but treatable cancers, while other patients with benign tumors undergo unnecessary invasive procedures. Now scientists have developed a new diagnostic tool that’s much easier to swallow – a pill that makes tumors glow under infrared light.

Researchers at ETH Zurich have developed a novel early warning system for four common types of cancer. An implant keeps watch for elevated levels of calcium in the blood – and warns the patient by growing an artificial mole on their skin.

Skin cancer is the most common form of the disease, but it usually requires a biopsy to confirm whether a mark is malignant or not. Now, an Australian team has developed a microbiopsy device that’s far less invasive, basically painless, and won’t leave a scar.
