We've previously heard about wound dressings that kill bacteria,
but now researchers at Australia's Swinburne University of Technology are
taking a different approach. They're creating a dressing material that
attracts bacteria out from within the wound, so that the material and
the microbes can then just be pulled off and discarded.
Working with a team of UCLA scientists, a man with protracted and complete paralysis has recovered sufficient voluntary control to take charge of a bionic exoskeleton and take many thousands of steps. Using a non-invasive spinal stimulation system that requires no surgery, this is claimed to be the first time that a person with such a comprehensive disability has been able to actively and voluntarily walk with such a device.
We've already heard about an electronics-packing mouthguard that can be used to detect serious impacts to the head.
Now, scientists at the University of California, San Diego have
developed one that could provide continuous readings of users' health
markers including lactate, cortisol and uric acid. It may be used to
monitor the well-being of people such as diabetics, to track the
performance of athletes, or to detect stress in soldiers.
A new system for growing heart tissue in the lab may make future heart, liver, and lung repair much easier. University of Toronto scientists have developed asymmetrical honeycomb-shaped 2D meshes of protein scaffolding that stick together like Velcro and imitate the environments in which tissue and muscle cells grow in the body.
A robot-assisted system developed at the University of Twente promises
to make medical procedures that use needles more precise. The system
allows flexible needles to be steered in real time to their target,
which negates issues with tissue and organs deforming from the contact
pressure or from any unforeseen obstacles that lie between the needle
and its target.
If someone is wheezing, it usually means that they have a respiratory problem. Soon, however, a wheeze-analyzing wearable device may allow doctors to know what sort of respiratory problem a patient has – and how serious it is.
Because they often have weakened immune systems and/or blood flow
restrictions, diabetics run a heightened risk of serious infection from
even the smallest of open wounds. That's why a team of scientists from
Egypt's Alexandria University have developed a means of getting those
wounds to heal faster – silver-impregnated dressings.
When blood clots form in the aftermath of a heart attack or stroke, medications can be deployed to break them apart, but delivery is tricky. Getting the medicine to the clot takes some guesswork and there's no guarantee it will arrive in the right dosage, with complications like hemorrhaging a real possibility. A team of Australian scientists has developed a new approach that sees the drugs carried safely inside a nanocapsule, opening up the treatment to more patients and lessening the chance of side effects.
With a lack of clear symptoms even when the disease is well progressed, more than 80 percent of pancreatic cancer diagnoses come after the cancer has already spread. This has led some researchers to look beyond blood to urine testing, which is a less complex fluid. Among those is a team at the Queen Mary University of London, which has uncovered a three-protein biomarker in the urine of pancreatic cancer sufferers, suggesting a less invasive, early stage test may be on the way.
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.
