DOI: 10.48550/arxiv.2404.07811 Through experiments, three physicists from the University of Rennes, Aoyama Gakuin University, and the University of Lyon discovered that it is the friction between the fibers that causes knitted fabric to take on a specific shape. Jérôme Crassou, Samuel Pointcru, and…

Research reveals earliest evidence that humans used fire to shape Tasmania’s landscape
Emerald Swamp, Three Hammock Island. Credit: Simon Haberle Some of the first humans to arrive in Tasmania more than 41,000 years ago used fire to shape and manage the landscape, some 2,000 years earlier than previously thought. A British-Australian research team analyzed charcoal and pollen in ancient mud to uncover how Tasmanian indigenous people shaped their surroundings. This is the…

Researchers uncover dynamic processes that shape the Arctic seafloor
Repeated surveys by MBARI’s ocean floor mapping autonomous underwater vehicle have revealed unique landforms, including the rapid formation of giant craters and large mounds, on the edge of Canada’s Beaufort Sea continental shelf. Credit: : Eve Lundsten, MBARI MBARI researchers, working with a team of international collaborators, have discovered a large underwater ice formation at the edge of Canada’s Beaufort…

Mars’ unique shape may be the result of a long-lost moon, according to a new hypothesis.
Mars is being deformed by its putative moon Nerio. Source: arXiv (2024). DOI: 10.48550/arxiv.2408.14725 A U.S. Naval Observatory astronomer has come up with a hypothesis to explain Mars’ unique shape and topography, both of which he suggests are the result of a long-lost moon. Michael Efroymsky has published a paper outlining his hypothesis on the arXiv preprint server. Previous studies…
