A Wildfire Early Warning System
Every year, forest fires take a huge toll all over the world. In 2021, the United States alone spent more than US$4 billion fighting wildfires. Better ways to spot and douse the flames before they roar out of control are needed, and that is where Berlin-based start-up Dryad Networks has stepped in.
The company has developed a small solar-powered sensor that can be mounted on trees. This "electronic nose" can detect the hydrogen, carbon monoxide and other compounds that are released when a fire starts smouldering, alerting officials via wireless signal before smoke is even visible above the trees.
In a recent test run in Germany, the sensor picked up a (deliberately lit) fire within 14 minutes. It also provides exact GPS coordinates so firefighters can rush to the scene. Forest regions from California to the Italian island of Sardinia are now trying out these inexpensive sensors, and Dryad aims to deploy 120 million of them by 2030, potentially saving a projected four million hectares from burning.
A Brain Implant That Overcomes Paralysis
Stunning advances in neurotechnology are bringing real hope to people with spinal injuries. One man has been able to walk again simply by thinking about it, thanks to a digital brain-spine interface, created by Swiss researchers, that boosts neural signals damaged by the injury.
Gert-Jan Oskam, a 40-year-old from the Netherlands, has required a wheelchair since he was paralyzed in a cycling accident 12 years ago. But electronic implants in his brain now allow him to transmit his silent intentions to a receptor implanted in his spine. The implant then amplifies and sends signals to his legs and feet through his nerve cells.
