3D hydrogel biochips offer better diagnosis of early-stage bowel cancer

Early detection is paramount to survival from bowel cancer, but doing so is difficult because most symptoms don't present until the cancer matures. Worse, existing diagnostic tests tend to be invasive and traumatic. Russian scientists hope to change this with a new biochip technology that can gather better, more precise data for diagnostic analysis. The scientists report that their new method far outstrips traditional methods of diagnosing bowel cancer. Read More

Diagnostic blood test shows promise in early detection of Parkinson's

Early detection of Parkinson's could help doctors decide on treatment options or improve disease management. But often people get a neurological examination after symptoms appear, when vital brain cells have already been destroyed. Now a game-changing blood test is being developed to give doctors a reliable method to detect the disease earlier through clinical biomarkers.Read More

Newly identified biomarkers flag potential for better asthma diagnosis and treatment

Asthma is a disease that affects some 25 million people in the US alone, but there's currently no definitive test for diagnosing it. New research could change that, with scientists at the Penn State College of Medicine identifying molecules that circulate in patients' blood, signalling that they have the disease. Not only could the breakthrough lead to a new diagnostic test, but it could also allow for the development of new, more targeted treatments.Read More

To diagnose autism, watch the eyes

When diagnosing autism spectrum disorder (ASD) in children, doctors currently rely on reports from parents, and direct observations, but those methods don't always produce concrete results. Now, researchers at the Cleveland Clinic have looked to remote eye tracking to help streamline the process, providing a solid, early diagnosis that lets treatment start more quickly.Read More

Odoreader accurately detects prostate cancer from urine

Standard prostate-specific antigen (PSA) tests for prostate cancer are far from ideal, sometimes resulting in unnecessary biopsies, and even failing to detect some cancers altogether. With the goal of developing a more capable alternative, a team of researchers has turned to a machine it calls the Odoreader, which is designed to analyze urine samples to provide a non-invasive prostate cancer test.Read More

Scientists uncover potential biomarker and drug target for autism

Improving our understanding of what causes autism spectrum disorder (ASD) can not only lead to better drugs to treat it, but more precise methods of diagnosis. Though progress has been made, as it stands there are no reliable biomarkers for ASD, with previous research implicating hundreds of genes in the condition which has muddied the waters somewhat. But now a team of scientists has zeroed in on defects in a particular signaling pathway that may be responsible for cognitive impairments associated with the condition.Read More

Study successfully uses drones to transport blood samples

We’ve already heard about drones being used to deliver pharmaceuticals to patients in remote locations, but scientists from Johns Hopkins University and Uganda’s Makerere University are now looking at the other end of the picture – using them to deliver remotely-located patients’ blood samples to labs in larger centers. According to a proof-of-concept study conducted by the researchers, the little unmanned aircraft should be able to do the job just fine.Read More

LabDisk diagnoses multiple diseases within an hour

Typically, tests for diseases must be done one disease at a time, and can take days to be processed through a lab. A new device developed in an EU project, however, can test for several diseases at the same time and provide results within an hour. The LabDisk is designed for use in Africa.Read More
