Radiation generally comes under the heading of "things you want to stay away from," so it's no surprise that radiation shielding is a high priority in many industries. However, current shielding is bulky and heavy, so a North Carolina State University team is developing a new lightweight shielding based on foam metals that can block X-rays, gamma rays, and neutron radiation, as well as withstanding high-energy impact collisions.
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 new conductive, transparent, and stretchable nanomaterial that folds
up like an accordion could one day be applied to the development of
flexible electronics and wearable sensors, as well as stretchable
displays. The researchers at North Carolina State University who created
this "nano-accordion" structure caution that it is early days yet, but
they hope to find ways to improve its conductivity and eventually scale
it up for commercial or industrial use.
