I'm getting really interested in Triggers, but the rest of the stories in this issue of Analog missed the mark. The "mark" is whatever pleases me at the moment.

• Serial: Triggers, part II of IV, by Robert J. Sawyer - An assassin shoots President Seth Jerrison during a speech, and while at the hospital, an experiment elsewhere in the building goes haywire and accidentally links the President into a telepathic mind-reading chain. With top-secret military operation mere hours away, a spy reading the President's thoughts could be catastrophic for national--and world--security.
• Novelette: The Ediacarian Machine, by Craig DeLancey - A machine is found encased in Ediacarian (i.e., Precambrian) rock, and explored with remote-control micro-robots.
• Novelette: Upon Their Backs, by Kyle Kirkland - Six naked bodies, perfectly preserved in apparent suspended animation, are discovered in a cave--then two escape from the morgue.
• Short story: Mother's Tattoos, by Richard A. Lovett - Would you sell your soul and get a terrorist-detecting tattoo in exchange for a monthly stipend?
• Short story: Ernesto, by Alec Nevala-Lee - People are being cured of cancer after visiting a holy site in Spain during the Spanish Civil War; it appears to be a miracle complete with the appearance of stigmata, but could it be just an erysipelas infection?
• Science Fact: The Earth Dies Screaming: Radiation Threats from Beyond, by Adrian L. Melott - Maybe it was fluke radiation bombardments that are behind the extinction events in Earth's history: the data doesn't rule it out, and it is statistically probable.
