Why can’t I fix my own phone, toaster, or tractor?


As critically ill COVID-19 patients started showing up in droves at emergency rooms around the world, ventilators became a crucial technology keeping patients alive. When hospitals’ own resources became overwhelmed, the Strategic National Stockpile dusted off and distributed thousands of the life-support machines throughout the country. But not all were in working condition. J. Scot Mackeil, a biomedical technician with more than 40 years of experience, worked on a team tasked with inspecting machines sent to Massachusetts’s Emergency Management Agency. In mid-April, while performing spot checks on hundreds of ventilators packed in freight pods, Mackeil discovered one with a damaged…

Why contact-tracing apps haven’t lived up to expectations

5 innovations shaping the future of train travel


What will the future of public transport look like? The major projects being planned today, such as the UK’s HS2 high-speed rail network, aren’t fundamentally different to what’s been built over the last 30 years. Maglev trains are largely confined to niche projects in China. Hyperloop remains an unproven glimmer in Elon Musk and Richard Branson’s eyes. The likes of HS2 can deliver considerable improvements in network capacity but through incremental changes in conventional designs, from tracks to train bogies. Yet while the rail sector is warily slow at introducing new technologies due to the long time it takes to…
