New findings add to a growing body of evidence indicating that type 1 diabetes is not a single disease. The presentation and, perhaps, cause of autoimmune diabetes differs among genetically high-risk children, the University of South Florida Health-led research suggests.

With age, the human heart gradually loses its ability to repair itself following injury. Damage wrought by injuries such as cardiac ischemia and heart attack, which are associated with decreased oxygen levels in the heart, can cause the heart to function below normal capacity, making it difficult for patients to carry out day-to-day activities. To augment heart repair after ischemic injury, researchers have turned to stem cell-based therapies, which replace dead heart tissue with new, functional tissue.

Scientists have created wearable, stitchable, and sensitive sensors from flexible polymers and bundles of carbon fibre. Like our skin, these sensors respond to pressure and can measure body position and movement. They could be used to measure disease progress in Parkinson's disease, or sense joint movement in athletes, for example.

What if we could identify proteins as easily as we can sequence DNA and RNA? Perhaps soon we will, thanks to new DNA Nanoswitch Calipers. DNA Calipers create a unique 'fingerprint' for peptides (the building blocks of proteins) by repeatedly applying force to them to generate a series of distance measurements for each peptide. This innovation opens up a new avenue for pursuing the goal of single-cell proteomics, and enables potentially life-saving discoveries in human health and disease.
