Flexible crosswalk lights that wrap around trees

Posted in Concepts by Conner Flynn on February 2nd, 2011

Crosswalk signs on metal posts are fine, but here’s something that makes much more sense. This flexible LED crosswalk light that can be fastened around a tree, killing two birds with one stone. And it encourages trees in cities, which is always good.

It’s called the “Wearable Signal,” and comes from Korean designers, Gisung Han, Hwanju Jeon, and Jaemin Lee. They see it as an eco-friendly way to manage street traffic. They can be wrapped around any cylindrical pole, but trees are obviously best.

Study finds Wi-Fi radiation bad for trees

Tree-huggers won’t like this news. Results from a preliminary study by DU Delft University, Wageningen University, and other institutions in the Netherlands show that WiFi radiation may be harmful to trees. The study found that WiFi radiation may cause bleeding and fissures in tree bark, which were not caused by any virus or bacteria.

According to their data, 70% of trees in urban spaces are now showing signs of damage compared to just 10% five years ago. Trees located the closest to WiFi radiation exhibited a lead-like shine on the leaves and death of the leaves’ lower and upper epidermises. Radiation from WiFi was also found to inhibit the growth of corn cobs.

Carnegie Mellon’s robot snake now climbs trees

Posted in Robots by Conner Flynn on September 6th, 2010


The way we see it, humans have just two deeply rooted fears. Both are completely justified. Robots and snakes. Well,now Carnegie Mellon has combined both effectively and taught its robotic snake how to climb trees. “Uncle Sam” is a modular snake robot and the latest in a line of snakes from Carnegie Mellon’s Biorobotics Lab. Uncle Sam can roll, wiggle and side-wind with the best of them.

Now that it can wrap itself around a pole and climb vertically, it can therefore climb trees. Maybe even pluck an apple and offer it up to an Eve-bot. We were scared of robot snakes before, but now it might truly be time to whimper and hide somewhere and wait out the coming robotpocalypse.
