Researchers uncover link between neurodegenerative diseases and molecular scaffold

Researchers from King's College London (KCL) claim to have uncovered a link between a molecular scaffold, that allows for interaction between key components of a cell, and the debilitating effects of neurodegenerative diseases. It is possible in the long term that this line of research will yield a new target for tailored treatment in the fight against devastating afflictions such as dementia and motor neuron disease.

Vibrating capsule treats constipation by buzzing the intestine

According to Dr. Yishai Ron, a researcher at Tel-Aviv Sourasky Medical Center, nearly half of the people who take medication for chronic constipation are unsatisfied with the results. That dissatisfaction can stem from unwanted side effects, concerns over the long-term safety of the medication, or "the fact that it simply doesn’t work." That's why he and his colleagues have created an oral capsule that relieves constipation by vibrating its way along the intestinal tract. Read More

Smartphones could become disease-diagnosing tricorders

We've recently seen a number of projects aimed at creating Star Trek-like medical tricorders, that take the form of stand-alone electronic devices built specifically for the purpose. Now, however, scientists at the University of Houston are taking an approach that's currently popular in many other areas of product design – they've asked, "Why build a whole new device, if a smartphone can provide the electronics?". The result is a proposed phone lens attachment, that could be used to diagnose diseases in real time. Read More

Compound in fruits and vegetables prevents symptoms of Alzheimer's disease in mice

Alzheimer's disease represents the most common form of dementia, with the early stages of the disease generally characterized with short term memory loss and learning difficulties that increase in severity as the patient progresses in age. Scientists at the Salk Institute for Biological Studies, California, have discovered that with regular treatments of the antioxidant fisetin, they were able to prevent memory loss in mice with genetic mutations linked to Alzheimer's.

Stamp of approval for new living cell printing technique

Researchers in Houston have developed a cost effective method for printing living cells, claiming almost a 100 percent survival rate. The method, which is akin to a modern version of ancient Chinese wood block printing, allow cells to be printed on any surface and in virtually any two dimensional shape. And while current inkjet printers adapted to print living cells can cost upwards of US$10,000 with a cell survival rate of around 50 percent, this simple new technique could see the cell stamps produced for around $1.

"Living liquid crystal" could be used to detect diseases earlier

With any medical condition, the earlier it's detected, the better the chances are of successfully treating it. When assessing biological samples from a patient, however, it's often quite difficult to see the indicators of a disease when it's still in its early stages. That could be about to change, thanks to the development of a solution known as "living liquid crystal." Read More

New laser shines a light on breath testing for disease

Various institutes around the world have long touted the potential of breath testing as a form of early and non-invasive disease detection. Now a research team from Australia's University of Adelaide has developed a new kind of laser with the ability to detect low concentrations of gases, opening up even more possibilities for disease diagnosis and other applications such us measuring the concentration of particular greenhouse gases in the atmosphere.

3D-printed hip implant lets teenager walk again

Much of the fanfare surrounding 3D printing has centered on its enabling consumers to create objects themselves, potentially circumventing traditional production models. Alongside NBA figurines and 3D printed pizza, however, the technology continues to provide valuable solutions in the field of medicine. Mobelife, a Belgium-based implant design company, has 3D printed a custom hip implant and given a once wheelchair-consigned teenager the ability to walk on her own. Read More
