The \u201cflash of light\u201d only refers to the \u201cinorganic signature\u201d of the \u201czinc spark\u201d detected with fluorescence microscopy in the laboratory\u2014an analytical technique. Calcium levels rise in the egg when a sperm enters it. These high calcium levels cause zinc to be released outside the egg. Researchers wanted to\u00a0<em>see<\/em>\u00a0the zinc, so they simulated fertilization in the lab and put the eggs in a solution containing a fluorescent tag (<a href=\"https:\/\/www.thermofisher.com\/order\/catalog\/product\/F24195\">FluoZin\u2122-3<\/a>). When the zinc is released, it is chemically labeled because this tag bonds to it. The tag (also called a fluorophore) can be illuminated with light of one color, and it emits light of a different, specific color. That \u201cfluorescence\u201d can be detected under a suitable microscope, thus revealing the zinc.]<\/span><\/div>\n<div>+<\/div>\n<div><\/div>\n<\/div>\n<\/div>\n<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<div class=\"gsp_post_data\" \r\n\t            data-post_type=\"post\" \r\n\t            data-cat=\"commentary\" \r\n\t            data-modified=\"120\"\r\n\t            data-created=\"1754700111\"\r\n\t            data-title=\"When Sperm Enters An Egg\" \r\n\t            data-home=\"https:\/\/spiritdaily.org\/blog\"><\/div>","protected":false},"excerpt":{"rendered":"<p>When a sperm fertilizes an egg, a visible &#8220;spark of light&#8221; or &#8220;zinc spark&#8221; occurs.
