Blood test for multiple cancers studied in 10,000 women, and is our Sun boring?

Staff Writer Jocelyn Kaiser joins Sarah to talk about a recent Science paper describing the results of a large study on a blood test for multiple types of cancer. The trial’s results suggest such a blood test combined with follow-up scans may help detect cancers early, but there is a danger of too many false positives. And postdoctoral researcher Timo Reinhold of the Max Planck Institute for Solar System Research joins Sarah to talk about his paper on how the Sun is a lot less variable in its magnetic activity compared with similar stars—what does it mean that our Sun is a little bit boring?   This week’s episode was produced with help from Podigy.
