  The Invention of a Gel which stops bleeding instantly Joe Landolina is a young, full time student at New York University, at age 17 he invented of a gel that can instantly stop traumatic bleeding — without the need to apply pressure. He created a gel that forms a clot within ten seconds and permanently heals the wound within few minutes. The gel is made up of tiny individual plant polymers; the gel is injected into the wound site. Once it hits the damaged tissue, whether it's open skin or a biopsied soft organ like livers, kidneys, spleens — the gel instantly forms a mesh-like structure, this simply means that the gel will make a very strong adhesive that hold the wound on the skin together. In simple word, when applied to an open wound, Veti-Gel bonds to the surrounding flesh, forming a tight seal. Not only does the gel initiate the blood clotting process, it also speeds healing . On the other hand the mesh like a matrix structure helps the body produce fibrin at the w...

A 50-cent microscope that folds like origami Manu Prakash an Indian bio engineer a student of from Stanford University who was on mission to bring radical new technology to global health, once he traveled to a mosquito-infested rainforest in Thailand a couple of years ago, there he visited a clinic where there were $100,000 microscope that sat idle in a locked room. It was then Prakash realized that what global health workers really need is a low cost, simple-to-use, portable microscope that could be arranged in the field to diagnose disease and decided to develop one himself. As a result he developed a Foldscope - a ‘use and throwaway’ microscope that Prakash made out of thick, waterproof paper and a glass, polymer lens that’s the size of a large grain of sand. While it can be used by simply holding the device up to the sun or a light bulb, there’s also a version illuminated by tiny LEDs powered by an inexpensive watch battery. The framework of the Foldscope is printed onto a sh...
