Genetic genealogy has been used to identify more than 40 murder and rape suspects in some cases at least 50 years old. There was always questions as whether using this investigative technique would hold up in court and now we have an answer. William Talbot II was tracked down through DNA that two cousins uploaded to a genealogy site, and was just found guilty of the murder of a young Canadian couple in 1987. Megan Molteni, science writer for Wired, joins us for the big win for genetic genealogy.
Next, as plastics continue to overtake the world, scientists are making progress in developing new ways to break down plastic and keep them out of landfills and the ocean. Scientists have now created a biological enzyme that can digest plastic into their chemical components so that it can be re-used. Corinne Iozzio, executive editor at Popular Science, joins us for the latest on plastic eating enzymes.
Finally, it’s almost the 4th of July… and with that comes fireworks. While nothing says America quite like bright exploding lights in the air, it can cause a terrible situation for the thousands of people that get hurt when they go off, birds in the air, and man’s best friend. Caitlin Gibson, feature writer for the Washington Post, joins us for why you should always be careful during the holiday and watch out for ruptured globes.
