Upcycling leftover cardboard to make a new type of foam packaging      (via sciencedaily.com)     Original source 

With the holiday season in full swing, gifts of all shapes and sizes are being shipped around the world. But all that packaging generates lots of waste, including cardboard boxes and plastic-based foam cushioning. Rather than discard those boxes, researchers have developed a cushioning foam from cardboard waste. Their upcycled material was stronger and more insulating than traditional, plastic foam-based cushioning.

Ultra-hard material to rival diamond discovered      (via sciencedaily.com)     Original source 

Scientists have solved a decades-long puzzle and unveiled a near unbreakable substance that could rival diamond, as the hardest material on earth, a study says. Researchers found that when carbon and nitrogen precursors were subjected to extreme heat and pressure, the resulting materials -- known as carbon nitrides -- were tougher than cubic boron nitride, the second hardest material after diamond.

Twenty-year study confirms California forests are healthier when burned -- or thinned      (via sciencedaily.com)     Original source 

A 20-year experiment in the Sierra Nevada confirms that different forest management techniques -- prescribed burning, restoration thinning or a combination of both -- are effective at reducing the risk of catastrophic wildfire in California. These treatments also improve forest health, making trees more resilient to stressors like drought and bark beetles, and they do not negatively impact plant or wildlife biodiversity within individual tree stands, the research found.

New conductive, cotton-based fiber developed for smart textiles      (via sciencedaily.com)     Original source 

A single strand of newly developed fiber has the flexibility of cotton and the electric conductivity of the polymer, polyaniline. The new material has shown good potential for wearable e-textiles. The researchers tested the fibers with a system that powered an LED light and another that sensed ammonia gas. While intrinsically conductive, polyaniline is brittle and by itself, cannot be made into a fiber for textiles. To solve this, the researchers dissolved cotton cellulose from recycled t-shirts into a solution and the conductive polymer into another separate solution.
