Top New Science Podcasts: Blood Tests For Multiple Cancers, Our Quiet Sun

science-magazine-podcastsStaff 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?

Personal Health: “Singing The Praises Of Prevention” (The Scientist Magazine)

From Bob Grant, The Scientist Magazine (April 1, 2020):

Prevention has been playing a growing role in other diseases, infectious and Singing the Praises of Prevention - The Scientist April 2020 - By Andrzej Krauzeotherwise, long before this latest global pandemic. Cancer, the focus of this issue, is ubiquitous, and one would be hard pressed to find a person anywhere on Earth whose life wasn’t in some way touched by the complex and vexing malady. 

This cancer-focused issue features a cover story in which we explore one facet of cancer prevention: exercise. In this feature story, Danish researcher Bente Klarlund Pedersen explains that studies have shown frequent exercise to be useful in avoiding cancer as well as in helping cancer patients lessen the side effects of their cancers and treatments. Her research and that of others is seeking to enumerate the molecular and cellular mechanisms that underlie the benefits exercise seems to offer cancer patients. 

But when one considers the practical ripples that biology sends through societies—issues of public health and the shared goal of minimizing the impact of diseases on a global scale—human behavior and prevention become vitally important.
