Non-invasive spinal cord stimulation gets paralyzed legs moving voluntarily again

Five men with complete motor paralysis have regained the ability to move their legs voluntarily and produce step-like movements after being treated with a non-invasive form of spinal cord stimulation. The new treatment builds on prior work to generate voluntary movements in paralyzed people through electrical stimulation – in particular, two studies (one completed in 2011, the other in 2014) that involved surgically implanting an electrode array on the spinal cord. This time, however, the researchers found success without performing any invasive surgery.

Harnessing the survival powers of cancer cells could wipe out heart disease

The same genes that allow many cancers to proliferate and thrive could in the future be repurposed as a force for good. A study at the San Diego State University (SDSU) Heart Institute has found that mouse hearts regenerate cells better, causing the mice to live longer, when their progenitor cells are modified to over-express a key gene in cancer production. The researchers believe this could lead to a new treatment for people with heart disease or who have suffered from other age-related cardiac problems.

CERN develops miniature linear accelerator for medical use

The Large Hadron Collider (LHC) at CERN is where the miraculous meets the impractical. In addition to probing the secrets of the Universe at the subatomic level, it also has potential for a variety of medical applications. Unfortunately, with a circumference of 27 km (16.7 mi) the LHC is so unwieldy that it would be about as practical as using Big Ben for a wristwatch. In the hopes of creating something a bit more useful for the medical fraternity, CERN engineers have come up with a miniature linear accelerator (mini-Linac) that, at 2 m (6.5 ft) long, is small enough to be set up in hospitals for medical imaging and radiotherapy applications.

Firefly enzyme inspires Swiss team to create portable disease test kit

Portable test kits represent an advance in disease diagnosis, as their ready availability increases chances of earlier detection and treatment. This type of technology is constantly evolving, and sometimes inspiration can come from surprising sources. Such is the case with research carried out by a Swiss team, which has borrowed from the mechanics behind the firefly's glow to develop a sensitive molecule detector.

Silk-based functional inks put biosensor data on your fingertips

Although we've seen "bio-inks" that allow sensors to be drawn directly on a person's skin and other surfaces to gauge things like glucose levels, functional inks such as this are usually heat-sensitive, meaning they aren't suitable for use in inkjet printers. Researchers at Tufts University have now developed silk-based inks containing bacteria-sensing agents that can withstand the rigors of inkjet printing, opening the door much wider for printing biomolecules.

Needle-sized mechanical wrist gives surgery a new angle

Some of the most difficult types of surgery just got easier and more versatile. A team of engineers and doctors at Vanderbilt University has developed a tiny mechanical wrist that can be used for millimeter-sized incisions and sutures that allow new kinds of operations and less-invasive ways of conducting existing procedures. The wrist is flexible enough that its end can be steered to allow needles to reach inside the nose, throat, ears, urethra, and brain.

Eye drops could spell the end of cataract surgery

People suffering from cataracts aren't exactly flush with options when it comes to restoring their vision. As they grow over time, they start to impede the ability to perform everyday tasks like reading and driving, prompting surgical removal either by scalpel or laser. But new research suggests a less invasive solution might be on the way in the form of a naturally-occurring molecule that can be administered through a simple eye drop.

Mussel-inspired surgical glue shuts down bleeding wounds in 60 seconds

The ability of mussels to stubbornly bind themselves to underwater surfaces has intrigued scientists for years. If this ability could be recreated in the lab, it could lead to new adhesives for all kinds of applications. A team of Korean scientists has now developed a surgical glue inspired by these natural wonders that's claimed to be cheaper, more reliable and incur less scarring than existing solutions.
