Brain Implant Bypasses Eyes To Help Blind People See (5 minute read)

Scientists from the University of Pennsylvania's Perelman School of Medicine have devised a way to use a brain implant to stimulate the visual cortex to produce a relatively clear and functional kind of bionic vision. Dynamic current steering involves tracing shapes with electricity onto the brain's surface. The Orion system uses an eyeglass-mounted video camera to send information to an electrode array on top of the brain's visual cortex. It is currently limited in resolution due to engineering limitations. Six patients have received the implant so far and it has allowed them to see letters as they are drawn. A short video is available in the article that shows one of the patients detecting letters as they are drawn on a screen.

China experiencing a drone β€˜revolution’ in agriculture (4 minute read)

The great rebalancing: working from home fuels rise of the 'secondary city' (5 minute read)

The number of Americans working from home skyrocketed between February to May. Studies have shown that most workers report being equally or more effective since working from home, and most intend to continue with it in some form post-pandemic. A permanent change in work culture will have far-reaching repercussions. As people are required to commute less, they may move further away from cities. Cities will likely become less congested, and towns and rural areas will likely have an opportunity to grow.
