Publisher's Summary

Scientists who have long wondered why the polarity of the Earth's magnetic field occasionally reverses may finally have their answer. Also, a look at how the online industry is stepping up its measures to thwart electronic junk mail, a new way of approaching long-term problems that focuses on flexibility rather than cost-benefit analysis; and surprising similarities between humans and animals when it comes to dealing with personal economics.

Love the content, do not like the narrator

Because I have always been a fan of the print mag, I thought listening to the news would be equally enjoyable, but the narrator's monotonal style is irritating and his variations in volume are distracting. I would like to know the name of the narrator so I can avoid him, but I see no listing of narrators for these mags! (why is that?)
