Scientists Are Teaching Drones to Find Lost Hikers

Scientists in Switzerland are developing drones that can pick out forest trails as skillfully as an expert hiker. The drones use a color camera to identify footpaths through wooded areas and are equipped with deep neural network software (the same technology that allowed Google Deep Dream to create those nightmare images) that has been programmed to recognize the signs of a trail and to avoid overhanging branches and vegetation. Though the drones are still in development, they could one day help rescue teams find lost hikers.

According to Entrepreneur, the artificially intelligent drones are a step up from others because they are able to fly below the tree canopy, keeping close to hiking and biking paths where travelers are most likely to get lost. They are also autonomous and can even identify overgrown paths better than some humans.

"Interpreting an image taken in a complex environment such as a forest is incredibly difficult for a computer," explains Dr. Alessandro Giusti, one of the researchers from the Dalle Molle Institute for Artificial Intelligence working on the project, in a press release. “Sometimes even humans struggle to find the trail!"

Researchers believe that, eventually, drones will work in conjunction with search and rescue teams to reduce the workload of rescue workers and help hikers get rescued faster. “Many technological issues must be overcome before the most ambitious applications can become a reality. But small flying robots are incredibly versatile, and the field is advancing at an unseen pace,” says Luca Maria Gambardella, director of the Dalle Molle Institute for Artificial Intelligence. “One day robots will work side by side with human rescuers to make our lives safer."

Look Up! Residents of Maine and Michigan Might Catch a Glimpse of the Northern Lights Tonight

The aurora borealis, a celestial show usually reserved for spectators near the arctic circle, could potentially appear over parts of the continental U.S. on the night of February 15. As Newsweek reports, a solar storm is on track to illuminate the skies above Maine and Michigan.

The Northern Lights (and the Southern Lights) are caused by electrons from the sun colliding with gases in the Earth’s atmosphere. The solar particles transfer some of their energy to oxygen and nitrogen molecules on contact, and as these excited molecules settle back to their normal states they release light particles. The results are glowing waves of blue, green, purple, and pink light creating a spectacle for viewers on Earth.

The more solar particles pelt the atmosphere, the more vivid these lights become. Following a moderate solar flare that burst from the sun on Monday, the NOAA Space Weather Prediction Center forecast a solar light show for tonight. While the Northern Lights are most visible from higher latitudes where the planet’s magnetic field is strongest, northern states are occasionally treated to a view. This is because the magnetic North Pole is closer to the U.S. than the geographic North Pole.

This Thursday night into Friday morning is expected to be one of those occasions. To catch a glimpse of the phenomena from your backyard, wait for the sun to go down and look toward the sky. People living in places with little cloud cover and light pollution will have the best chance of spotting it.

The North Face's New Geodesic Dome Tent Will Protect You in 60 mph Wind

The North Face

You can find camping tents designed for easy set-up, large crowds, and sustainability, but when it comes to strength, there’s only so much abuse a foldable structure can take. Now, The North Face is pushing the limits of tent durability with a reimagined design. According to inhabitat, the Geodome 4 relies on its distinctive geodesic shape to survive wind gusts approaching hurricane strength.

Instead of the classic arching tent structure, the Geodome balloons outward like a globe. It owes its unique design to the five main poles and one equator pole that hold it in place. Packed up, the gear weighs just over 24 pounds, making it a practical option for car campers and four-season adventurers. When it’s erected, campers have floor space measuring roughly 7 feet by 7.5 feet, enough to sleep four people, and 6 feet and 9 inches of space from ground to ceiling if they want to stand. Hooks attached to the top create a system for gear storage.

While it works in mild conditions, the tent should really appeal to campers who like to trek through harsher weather. Geodesic domes are formed from interlocking triangles. A triangle’s fixed angles make it one of the strongest shapes in engineering, and when used in domes, triangles lend this strength to the overall structure. In the case of the tent, this means that the dome will maintain its form in winds reaching speeds of 60 mph. Meanwhile, the double-layered, water-resistant exterior keeps campers dry as they wait out the storm.

The Geodome 4 is set to sell for $1635 when it goes on sale in Japan this March. In the meantime, outdoorsy types in the U.S. will just have to wait until the innovative product expands to international markets.
