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.

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.

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.

Biomarker discovery points to blood test for osteoarthritis

While blood tests are used to rule out other forms of arthritis, the diagnosis of osteoarthritis (OA) generally relies on physical symptoms, with X-rays or MRI scans used for conformation if required. But researchers at the University of Warwick in the UK have identified a biomarker for OA that could lead to a blood test that could diagnose it, and rheumatoid arthritis (RA), years before physical symptoms present themselves.

Non-invasive MRI technique picks up early signs of Alzheimer’s disease

The development of brain plaques are thought to correlate with symptoms of Alzheimer’s disease, such as memory loss. Previous research has indicated that limiting these buildups could be the key to tackling the disease, but scientists from Northwestern University are digging a little deeper. The team has devised a non-invasive MRI technique capable of tracking the specific toxins that accumulate to form plaques, potentially enabling doctors to pick up early signs of the disease before it starts to take hold.

Mantis shrimp's eyes inspire new cancer-detecting camera

One of nature’s most notorious psychopaths may be giving cancer patients new hope. The mantis shrimp is famous for having a punch like a .22 bullet and a perpetual bad attitude, but is also has the most complex eyes in the animal kingdom, which are excellent at detecting polarized light. With this in mind, the University of Queensland is developing new cameras based on the mantis shrimp’s eyes that can detect a variety of cancer tissues. Read More

Blood test provides first objective diagnosis of depression in adults

Diagnosing depression can be a difficult task, currently relying on patients reporting symptoms – something those suffering depression don't always do – and doctors correctly interpreting them – which isn't easy as the symptoms are non-specific. Now researchers have developed a blood test to diagnose depression in adults, providing the first objective, scientific diagnosis for the condition. Read More
