Can Gold Nanoparticles Help Predict Heart Attacks?
1/20/2015
Engineers from the NYU Polytechnic School of Engineering, in collaboration with Peking University researchers, have been developing a new, more sensitive test strip for a biomarker common in heart attack victims. The team created a new fabrication approach that makes colloidal gold nanoparticles with an increased sensitivity for this biomarker, which could provide early detection for heart attacks.

3D Facial Imaging May Help Diagnose Autism Earlier
1/17/2015
Earlier diagnosis of childhood autism may now be possible using 3D facial imaging. A new method developed by researchers from the University of Missouri uses software algorithms to find trends in the facial features of autistic patients. They discovered that certain features seem to be characteristic of autism, which may allow for more effective treatments to begin earlier.

Tattoo-Based Sensor Monitors Glucose Levels Without Finger Pricks
1/17/2015
An ultra-thin, flexible device has been developed by researchers to detect a person’s blood glucose levels. The device eliminates the need for the finger pricks often used by diabetics, and it works like a temporary, rub-on tattoo.

Web-Based TAVR Marketing Understates Risks, Overstates Benefits
1/16/2015
Transcatheter aortic valve replacement is much less invasive than open heart surgery, but like most procedures, it comes with risks. A recent study, however, shows that hospital web marketing for the procedure often fails to accurately convey these risks. In many cases, risk information was even left out, which may be doing patients a disservice.

Nanolaser Biosensor Performs Low-Cost, Label-Free DNA Detection
1/16/2015
A straightforward imaging method that eliminates the need for fluorescent labels may soon be available. The new approach developed by Yokohama University researchers could be used to detect DNA or proteins related to cancer by measuring changes in the laser’s wavelength and gauging its intensity when molecules are adsorbed in the system.

Functional Tissue-Engineered Intestine Grown Using Human Cells
1/15/2015
Taking stem cells normally found in the small intestine, researchers grew a tissue-engineered version that replicates many of the functions seen in normal intestinal tissue. The Children’s Hospital Los Angeles team was able to show that the new tissue contained mucosal lining, supported structures, and had the ability to absorb nutrients. Eventually, it may help children with intestines that have been congenitally malformed.

“Nanoscopic” Imaging Technique Captures Neurotransmission On Camera
1/15/2015
A new breakthrough from Heriot-Watt University may provide significant insight into neurodegenerative diseases like schizophrenia and epilepsy. A new imaging technique has enabled researchers to capture the exact point and time that information is transferred during neurotransmission. Their research is focused on understanding synaptic events, which are often implicated in neurodegenerative diseases.

Solar-Powered “Diagnostics-In-A-Suitcase” Developed For Ebola Testing
1/14/2015
To deal with extreme field conditions, researchers have developed a self-contained diagnostics laboratory in a suitcase. Designed to perform Ebola testing, the diagnostic platform uses solar power and room temperature reactions to provide results in as little as 15 minutes.

Neural Implants Could Provide New Therapies For Paralysis
1/14/2015
A recently developed neural implant may offer new therapies for paralyzed patients. The device is an electronic and chemical interface that has been designed for long-term close-contact with the spinal cord or brain. By matching certain properties of the brain, the implant could reduce inflammation and scar tissues that have been problematic in the past.

Patient Leaves Hospital Without A Human Heart
1/14/2015
Thanks to a backpack-sized power supply, surgeons at the University of Michigan Frankel Cardiovascular Center sent a patient waiting for a heart transplant back home. Cardiac surgeons implanted a total artificial heart powered by a portable driver, allowing the patient to return home without receiving a transplant.
