The skin is the body's first line of defense against infection. And when this barrier is broken, or an internal organ is ruptured, it is the process of coagulation, or clotting, which relies largely on blood cells called platelets, that seals the breach and stems the flow of blood. Researchers at UC Santa Barbara have now synthesized nanoparticles that mimic the form and function of platelets, but can do more than just accelerate the body's natural healing processes.  Read More

The rHealth tool requires a single drop of blood and can diagnose ailments in minutes

For the last two years, the US$2.25 million Nokia Sensing X Challenge has lured entrants from around the globe to submit groundbreaking technologies that improve access to health care. A panel of experts have awarded this year's grand prize to Massachusetts-based DNA Medical Institute (DMI), whose hand-held device is capable of diagnosing ailments in minutes, using only a single drop of blood.  Read More

This smart watch-like device is designed to assist the elderly with basic tasks like remem...

As our life spans increase, more services and care will be needed for the elderly, especially those who live independently. Technology clearly has an increasing role to play in improving home care and health monitoring. The latest developments from German research group Fraunhofer are a case in point.  Read More

Glass slides dipped in blood to demonstrate the effectiveness of the TLP coating. with blo...

Our bodies have evolved to be pretty good at dealing with incursions by foreign objects and bacteria. Usually, that's a positive thing, but it can spell trouble for medical devices, such as replacement joints, cardiac implants and dialysis machines, which increase the risk of blood clots and bacterial infection. Now researchers at Harvard University have developed a surface coating that smooths the way for medical devices to do their job inside the human body.  Read More

John Kundzins of the Kidney Research Institute in Seattle models the Wearable Artificial K...

In 2009, we had a look at the Wearable Artificial Kidney (WAK) concept that promised patients suffering from kidney failure an alternative to conventional dialysis. Now the tool-belt sized prototype has been granted approval for human testing in the United States by the FDA with clinical trials scheduled to take place in Seattle later this year.  Read More

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

The prototype biospleen and components (Image: DARPA)

Today, when we think of the dangers of the battlefield, we think of wounds caused by bullets, bombs, and other weapons. But as late as the Spanish American war of 1898, the number of soldiers who died from infectious diseases as opposed to directly from combat injuries was seven to one. Thanks to the discovery of penicillin and other antibiotics, that ratio has swung dramatically the other way, but it’s still a major problem, not only for military personnel, but civilians too. DARPA is developing an artificial spleen, or "biospleen," as a way to help fight deadly infections without antibiotics.  Read More

A sample of the hydrogel turns from blue to green to red, as it takes up glucose

Thanks to a new color-changing hydrogel, there may soon be a more reliable way of continuously monitoring the blood glucose levels of both diabetics and hospital patients. If incorporated into a device such as an implanted pump, it could automatically trigger the release of insulin into the bloodstream as needed.  Read More

The benefits of using sound to separate cells over conventional more aggressive methods me...

Researchers from MIT, Carnegie Mellon University and Pennsylvania State University have developed a novel technique of separating cells with the use of a gentle sound wave. The technique could potentially be used to screen a patient's blood, allowing medical practitioners to isolate rare tumor cells synonymous with diseases such as cancer.  Read More

Scientists believe that a genetic mutation, which is detectable in blood samples, makes so...

While there are a wide range of scenarios that may cause a person to take their own life, the fact is that in a given situation, some people will do so whereas others won't. Scientists at the Johns Hopkins University School of Medicine now believe that this difference can largely be traced to a genetic mutation in the people who are more likely to commit suicide. What's more, this mutation can be detected via a blood test.  Read More
