4 Awesome Discoveries You Probably Didn’t Hear About This Week - Episode 28

The video explores four innovative research projects. First, researchers use shrink films to create strong, durable grippers for soft robotics. Next, a novel anti-ice coating is developed to prevent ice accumulation on large surfaces. Then, a method to produce hydrogen from industrial wastewater using sunlight is introduced. Finally, the impact of tree cover on urban temperatures is analyzed, showing significant cooling effects with sufficient tree density.
