Research suggests that targeting a protein in the brain could help prevent the development...

In recent years, research has linked sleep problems to Alzheimer’s disease. This relationship involves a neurotransmitter called orexin that awakens the brain from sleep and has shown to be heightened in moderate to severe sufferers of Alzheimer’s. New research conducted at Washington University in St Louis suggests that removing the orexin protein in mice enables them to sleep longer, which could serve to hinder development of the disease.  Read More

Researchers have developed coated magnetic nanoparticles that can be used to help regenera...

When a bone is severely broken in the human body, or a bone-fused prosthesis is implanted, a bone graft is also often required to ensure a solid mechanical repair. However, a graft that removes bone from another area of the body can be a painful and invasive procedure, and the mechanical stimulation required for continued bone regeneration in post-operative therapy becomes problematic if a patient is severely immobilized. To address these problems, researchers have discovered that coating magnetic nanoparticles with proteins and then directing them magnetically to the site of the injury can help stimulate stem cells to regenerate bone.  Read More

Artist's rendering of synthetic platelets that mimic, and outperform, natural platelets (I...

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

An x-ray displaying BoneFinder-enhanced hip bones

Despite what cartoons may have us believe, x-rays don't always show bones as being sharply defined from the surrounding tissue. It's often difficult to tell where the one ends and the other begins, requiring clinicians to go through the images and manually draw in the outlines of bones. Now, however, free software known as BoneFinder is able to do so automatically.  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

The activity of the SRPK1 molecule was found to be higher in cancerous (right) than benign...

In the spread of prostate cancer, one particular molecule is critical. Called SRPK1, it enables a tumor to generate new blood vessels and start to grow. Research conducted at the University of Bristol shows that a specific compound can thwart its activity, potentially leading to new forms of treatment for the disease.  Read More

A genetically-inherited microbe naturally found in the gut that is more common in thin peo...

A new study has determined that not only are bacteria naturally found in the gut involved in obesity, diabetes, and cardiovascular disease, but they are genetically inherited. Researchers at King's College London and Cornell University identified a highly-heritable bacterial family that is more common in individuals with low body weight and that could pave the way for genetics-based personalized probiotic therapies for obesity-related diseases.  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

EPFL researchers succeeded in recreating the feeling of a 'ghostly presence' in the labora...

Mountain climbers facing extreme climatic conditions, patients affected by schizophrenia or neurological disorders and athletes facing severe exhaustion have all reported experiencing feeling an invisible and yet persistent "presence" that is often felt just outside their field of view. Researchers at EPFL have now recreated the same sensations in perfectly healthy subjects, inducing ghostly hallucinations in a matter of minutes.  Read More

A new prototype device determines whether a prostate tissue sample is benign or malignant ...

European research organization Fraunhofer is set to present a prototype device for quickly diagnosing prostate cancer at the COMPAMED trade fair in Düsseldorf next week. Its creators claim that it can reliably determine whether changed tissue in the prostate is benign or malignant within just a minute-and-a-half, thanks to an on-board visual analysis of a sample gathered via biopsy.  Read More
