High school student designs pram for moms in wheelchairs

By Cathryn Wellner / November 6, 2015

The waterfront walk near my home is a favourite spot for running moms. They pop junior in an expensive pram and get their exercise while baby gets fresh air. Absent on the scene are moms in wheelchairs. Pushing a pram is not in the cards. Or at least it wasn’t. But a Detroit high school […]

By Cathryn Wellner / December 24, 2014

When my mother’s Alzheimer’s reached critical stage, she got lost the moment she stepped out her door. During one of my last visits to California to see her, we walked out of her small apartment. The day was sunny and warm, but she wore a wool cap and heavy jacket. She pulled her door shut, […]

Dr. Jeannette Armstrong welcomed us to her traditional territory, and then she did something we colonizers would never do to kick off a conference. She introduced her grandson, a 9-year-old boy who had […]

With governments, corporations and fossil-fuel companies still pretending we have time to futz around with business-as-usual energy schemes, innovators are doing an end run and coming up with alternatives. One place to check out some American ideas is on the Center for Social Inclusion’s site, Energy Democracy for All. Instead of ignoring the climate-change train […]
