Sunscreens: 2018 update

I don’t usually concern myself with SPF numbers on sunscreens as my primary focus has been on the inclusion of nanoscale metal particles (these are still considered safe). However, a recent conversation with a dental hygienist and coincidentally tripping across a June 19, 2018 posting on the Schrodinger’s Cat blog shortly after the convo. has me reassessing my take on SPF numbers (Note: Links have been removed), … So, what’s the deal with SPF?

Smart paint that ‘talks’ to canes for better safety crossing the street

It would be nice if they had some video of people navigating with the help of this ‘smart’ paint. Perhaps one day. Meanwhile, Adele Peters in her March 7, 2018 article for Fast Company provides a vivid description of how a sight-impaired or blind person could navigate more safely and easily, The crosswalk on a road in front of the Ohio State School for the Blind looks like one that might be found at any…
