Can Science Find An Antidote to Americium?

With some poisons, there’s an antidote — something you can take to block the effects of the poison, or to help remove it from your body. But when the harmful chemical is a radioactive element, options are limited. Iodine pills can be used to help block radioactive iodine I131 from being absorbed by the thyroid, but there aren’t many other drugs that can help deal with contamination with other radioactive substances. One of the two existing medications can only be delivered via IV in a clinic.

This week, the NIH announced the start of an early clinical trial for an oral drug delivered as a tablet that could potentially be used to bind and remove radioactive elements including plutonium, uranium and neptunium from the body. Rachel Feltman, editor at large at Popular Science, joins Ira to talk about that trial and other stories from the week in science, including an experimental universal flu vaccine, research into the amount of trace DNA humans shed every day, and an update on the planet Saturn’s moon count.

Much of what we think we know about the relationship between weight and health is based on a series of assumptions that don’t always match up with the latest science.

Laura Young was at a breaking point when she submitted a post titled “Request: Make 500-1,000 crows leave my street alone” to the subreddit r/lifeprotips in January. “I think you can tell that I was feeling very frustrated and running out of options and I clearly needed he
