Scientists discover ‘magical’ material that’s stronger than steel and lighter than aluminum — and its potential is dizzying

Scientists discover ‘magical’ material that’s stronger than steel and lighter than aluminum — and its potential is dizzying Story by Rick Kazmer • September 21, 2023 Galvorn is stronger than steel, lighter than aluminum, and has the conductivity of copper, according to an article on LinkedIn. While the jury is still out on whether it’s faster than a speeding bullet, experts at Houston-based DexMat suggest their product can revolutionize the green tech landscape. Galvorn can be an alternative to rare and expensive copper — a crucial metal in electronics, according to a report from GreenBiz. What’s more, the inventors plan to displace dirty materials, contribute to cleaner air, and advance green tech as their “magical” material is rolled out. Galvorn is the result of a more than $20 million investment from two U.S. Air Force research agencies, the Department of Energy, and NASA, among other tech heavy hitters, GreenBiz reports. “DexMat’s potential climate impact gets us dizzy,”

Evidence of a Wooden Structure That Predates Our Species Uncovered

Evidence of a Wooden Structure That Predates Our Species Uncovered Story by Mike McRae • September 20, 2023 A pair of interlocking logs that haven't seen sunlight in half a million years could challenge some fundamental assumptions about the technology and culture of our Stone Age ancestors. Uncovered in 2019 at the Kalambo Falls in Zambia, the objects provide archaeologists with an exceptionally rare look at wooden technology from mid-Paleolithic Africa, a time better known for an acceleration in the innovations of stone tools. The logs also predate the evolution of our own species, Homo sapiens. An analysis conducted by an international team of researchers has now come to the astonishing conclusion that the wooden artifacts were once part of a permanent structure of some kind, such as a platform or building. If so, the discovery complicates the conventional image of hominins as nomads hunting migrating herds or gathering seasonal flora with relatively basic tools. "Th
