Megalodon’s body size and shape reveal why certain aquatic vertebrates can achieve giants
Modified interim body outline for Otodus Megalodon, an extinct megatooth shark, at 24.3 meters (80 feet). Important notes: 1) The exact shape, size, and location of most fins remain unknown based on current fossil records. 2) Adult humans (Homo Sapiens) are drawn for size comparisons, but it must be emphasized that the two species do not coexist.

The double magical core of the Lead-208 goes against expectations with its amazing shape properties
Experimental setup to study Double Magic Lead-208. Credit: Argonne National Laboratory. anl.gov/article/welcome-back-gretina. In a surprising event, an international team of scientists discovered that the heaviest known “double magic” nucleus, Lead-208 (208pb), exhibits unexpected geometric properties that current nuclear models cannot be accurately predicted. Double magic refers to a nucleus with a full shell of both protons (82) and neutrons (126).…

Wearing Covids and Masks Outdoors: How Culture and Evolution Shape Our Behaviors
The willingness to wear outdoor masks during the Covid-19 pandemic was dependent on a variety of factors. Credit: Rebecca Haan, University of Tebingen An international research team led by Christophe Rander, a professor of biology education at the University of Tübingen, has revealed that people in collectivist societies like Japan have been involved in such individualistic countries during the Covid-19…

Liquid metals can mimic the behavior of leukocytes, including shape shifts and obstacle navigation
Autonomous behavior of chemotactic biomimetic liquid gold cells. Credit: Issue (2025). doi: 10.1016/j.matt.2025.101991 The scientists, led by Professor Li Jing of the Institute for Technical Physics and Chemistry at the Chinese Academy of Sciences (CAS), have created leukocyte-like liquid metallic entities that vividly simulate a variety of white blood cell behaviors. In an article published in Journal Matter on February…

The science behind Christmas sweaters: How friction shapes the shape of knitted fabrics
(a) Photograph of jersey knit stitches. (b) Experimental setup. (c) Geometric and numerical model. Credit: arXiv (2024). 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…
