For the new study, researchers at the Mayo Clinic analyzed health statistics collected by the World Health Organization. The resource included data from 183 countries, allowing the researchers to compare countries’ life expectancy and healthspans, which are calculated by years of life weighted by health status. Longer, but not better Overall, the researchers saw lifespan-healthspan […]

The No. 1 nuisance with smartphones and smartwatches is that we need to charge them every day. As warm-blooded creatures, however, we generate heat all the time, and that heat can be converted into electricity for some of the electronic gadgetry we carry. Flexible thermoelectric devices, or F-TEDs, can convert thermal energy into electric power. […]
