Study: Skin patch that dissolves fat in mice could help treat human obesity

Scientists have made a skin patch that dissolves fat in targeted areas on lab mice. It could be used to treat humans, if further testing reveals it's effective. The study's co-author called it a "noninvasive alternative to liposuction." The patch deploys drugs contained in nanoparticles too small to see. These particles enter the skin through painless microscopic needles. The particles dissolve fat near the patch (and not throughout the body). Scientists tested the patch by applying patches to both si
