Kirigami inspires better bandages
Scraped up knees and elbows are tricky places to securely apply a bandage. More often than not, the adhesive will peel away from the skin with just a few bends of the affected joint. Now MIT engineers have come up with a stickier solution, in the form of a thin, lightweight, rubber-like film. The adhesive film can stick to highly deformable regions of the body, such as the knee and elbow, and maintain its hold even after 100 bending cycles.
Method for 3D bio-fabrication based on bacterial cellulose
Bacterial cellulose (BC) nanofibres are promising building blocks for the development of sustainable materials with the potential to outperform conventional synthetic materials. BC, one of the purest forms of nanocellulose, is produced at the interface between the culture medium and air, where the aerobic bacteria have access to oxygen.
Ultrathin endoscope captures neurons firing in the brain
Researchers have developed an endoscope as thin as a human hair that can image the activity of neurons in the brains of living mice. Because it is so thin, the endoscope can reach deep into the brain, giving researchers access to areas that cannot be seen with microscopes or other types of endoscopes.
Unlocking the secrets of the human brain with honeybees
It has been discovered by researchers from the University of Sheffield that looking at honeybees in a colony in the same way as neurons in a brain could help us better understand the basic mechanisms of human behaviour.
Brain scanner allows patients to move freely
A new generation of brain scanner, that can be worn like a helmet allowing patients to move naturally whilst being scanned, has been developed by researchers at the Sir Peter Mansfield Imaging Centre, University of Nottingham and the Wellcome Centre for Human Neuroimaging, UCL. It is part of a five-year Wellcome funded project which has the potential to revolutionise the world of human brain imaging.
Portable arthroscopy system performs first cases in the UK
Trice Medical has announced the completion of its first successful case performed in the United Kingdom, after receiving CE Mark of approval in Europe for the mi-eye 2, as well as entry into Health Canada. Today’s case was performed by Mr. Tony Andrade, a Consultant Orthopaedic Surgeon at Circle Reading Hospital. “This is a fantastic opportunity to be able to show patients what’s going on inside their joints and talk them t...
'Brain stethoscope' turns brain waves into sound
When a doctor or nurse suspects something is wrong with a patient’s heart, there’s a simple way to check: put a stethoscope over the heart and listen to the sounds it makes. Doctors and nurses can use the same diagnostic tool to figure out what’s going on with the heart, lungs, stomach and more, but not the brain – although that could change with a new device.
Mending broken hearts with cardiomyocyte molds
Whether caused by an undetected birth defect or by a heart attack (myocardial infarction), when a heart sustains damage, it can be difficult to repair. 2.5 billion. That’s approximately the number of times the human heart beats in 70 years. And sometimes during the course of its unrelenting contractions and relaxations, the heart muscle can no longer bear the strain. If heart muscle cells—cardiomyocytes—could be repair...
Tiny implants for cells are functional in vivo
For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of living zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
Developing more sensitive cancer diagnostics
Detecting cancer in the body usually happens when the disease is already well underway to being mortally dangerous. Although there’s a myriad of cancers and ways to detect them, diagnostic tests typically look for biomarkers produced by tumors. And the bigger the tumor, the more biomarkers it releases, so the bigger it is the easier it is to detect. To get at the disease at its earlier stage, it would be useful to detect processes within ce...
