Scientists Transform Cabbage Into Stronger Concrete

A team of scientists at the University of Tokyo set out to make concrete from leftover food waste, including coffee grounds, tea leaves, onions, pumpkin, seaweed, orange and banana peel. The researchers didn’t just succeed, finding that all of the food (save for the pumpkin) created strong building material; but they also ascertained that Chinese cabbage crafts the sturdiest material—one that’s three times stronger than …

New Study Sheds Light on 45-Year-Old Alien Signal Mystery On 15 August 1977 at 10:16PM EST, Ohio State University’s Big Ear radio telescope scanned the Sagittarius constellation and detected a signal that was 20 times stronger than average, background emissions. When astronomer Jerry Ehman reviewed the findings the next morning, he wrote “Wow!” next to it, unknowingly naming the signal and its subsequent mystery. Since …

Face Masks Can Be Recycled to Create Stronger Concrete

New research published in Materials Letters announced that scientists at Washington State University found a way to recycle face masks by incorporating them into concrete, creating a more durable material that is 50% stronger than the standard. As face masks generate plastic pollution and concrete engenders a carbon-intensive process, the study not only improves concrete’s design, it also addresses two sustainability issues. Researchers found that …
