According to the International Diabetes Federation, 387 million people around the world suffer from diabetes, with this number expected to rise to 592 million by 2035. That adds up to a lot of blood sugar checks, diet watching and insulin shots, but researchers in the US have developed a patch that could revolutionize how the disease is managed. The patch contains of more than 100 microneedles, each automatically secreting insulin into the bloodstream when required.
A natural enzyme called catalase may prove hugely significant in treating neurological disorders such as Parkinson's. These extremely potent antioxidants can tackle neuron-killing inflammation with an effectiveness unparalleled by small molecule drugs. But there's a problem, they are big. So big that getting them through the blood-brain barrier for delivery straight to the brain is nearly impossible. But researchers have now discovered that loading them into tiny, naturally occurring bubbles allows them to sneak past the brain's defenses, pointing to the possibility of improved treatments for such conditions.
