Color-changing condoms could tell which VD you just got
A group of teenage inventors have struck upon a clever (albeit still very conceptual) way to alert folks to the presence of various venereal diseases before the burning starts: fluorescing condoms that light up when they encounter dangerous bacteria or virii. The team from Isaac Newton Academy in Illford, England developed the "glowing condom" concept, dubbed S.T.Y.E, as part of this year's TeenTech awards. It would reportedly operate as a normal condom does but also incorporate a sheath of molecules that attach to the diseases and set off a fluorescent reaction. The added layer would literally glow different colors when in contact with various STDs -- green for chlamydia, yellow for herpes, purple for HPV and blue for syphilis.
