Sci/tech tidbits in and around New Hampshire

The sci/tech columnist who went up a hill and wrote about a mountain
(This is my Concord Monitor column this week. If you want to hear me talk about it, and hear a colleague tell me that the premise of the whole story is baloney, check the podcast we made. It's only a few minutes long.) I have some shocking news. You may want to sit...

Before we delve into details of creating a clean-energy microgrid on scenic Appledore Island, a question: Would you rather hear about battery chemistry, recharge rates and load-balancing, or would you rather hear about bird poop on solar panels? Yeah, that’s what I...
Simple blood test could spot risk of sepsis, which kills hundreds of thousands of Americans
From Dartmouth-Hitchcock: Sepsis kills a quarter of a million Americans each year – as many as stroke and Alzheimer’s combined – but very little has changed in the treatment of this age-old scourge. Now an international group of researchers including...
