Fitbit can tell when I’m stressed

Fitbit can look at your resting heart rate over time. Minor complaint: I couldn’t download my resting heartbeat data into Excel, though. It’s hard to look back at resting heart rate history. I had to click back through the “date” function in the Dashboard and take screenshots of the graph every ~30 clicks/days. Google bought FitBit recently, and now the high-resolution heart rate data are available to Calico, I expect. That could be a big deal.

On my graph, you can see the rise preceding major grant deadlines. So that’s… cool? Cool. Cooool.

Designer DNA architecture offers precise and multivalent spatial pattern-recognition for viral sensing and inhibition

This was an interesting article on DNA nanotechnology applied to pathogen detection. The first step to detecting a virus is to bind a molecule to its surface. But virus-binding molecules can be weak. One way to make them better is to put a bunch of them together in an array. These smart folks made an array that has the shape of the virus, so all of the binding-molecules (called Aptamers) are nicely aligned.

Do You Know Where Your Healing Crystals Come From?

“I have a foreboding of an America in my children’s or grandchildren’s time … when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what’s true, we slide, almost without noticing, back into superstition and darkness.” –The Demon-Haunted World: Science as a Candle in the Dark by Carl Sagan
