Restoring Feeling in Lost Limbs

Having been in the military for twenty years, I’m very sympathetic to anyone who has lost a limb.  Great progress has been made in fabricating lifelike and functional prosthetics, but they still have one major disadvantage —  feeling.  There is no sensation in metal and plastic.  So the only way to control an artificial hand,

How To Think Better

Who wouldn’t like to be better at solving problems?  Recently, I ran across something that might help.  It involves using “mental models” to think in different ways.

How do you know if a marriage will last?  This is definitely out of my area of expertise, but I’ve run across someone who has developed some signs to watch for. One neutral observer who spends a lot of time with the couple.  A wedding photographer. A group of professional wedding photographers have compiled a

My last post highlighted water shortages, using Cape Town, South Africa as an example, and one agricultural solution being tried in Oklahoma.  As a follow-up, the BBC has published a list of the eleven other cities most likely to run out of drinking water.  If you’re wondering if you live in a vulnerable area, the
