Further analysis by researchers produced... view more  Credit: STScI, Alyssa Pagan Images of two iconic planetary nebulae taken by the Hubble Space Telescope are revealing new information about how they develop their dramatic features. Researchers from Rochester Institute of Technology and Green Bank Observatory presented new findings about the Butterfly Nebula (NGC 6302) and the Jewel Bug Nebula (NGC 7027) at the 237th meeting of the America...

Paulson School of Engineering and Applied Sciences have now developed a mathematical model to help explain how termites construct their intricate mounds. The research is published in the Proceedings of the National Academy of Sciences. "Termite mounds are amongst the greatest examples of animal architecture on our planet," said L. Mahadevan, the Lola England de Valpine Professor of Applied Mathematics, of O...

 E-Mail IMAGE: New research can help ecosystem managers identify species vulnerabilities and prevent populations from becoming at risk, like the endangered Mexican gray wolf. view more  Credit: U.S. Fish and Wildlife Service More than 3,000 animal species in the world today are considered endangered, with hundreds more categorized as vulnerable. Currently, ecologists don't have reliable tools to predict when a species may become at risk. A new paper published in Nature Ecology and Evolution, "Management implications of long transients in ecological systems," focuses on the transien...

 E-Mail IMAGE: Using computer simulations built on reasonable assumptions and conducted under careful control, computational bioscientists can mimic real biological conditions. Starting with the original founding population (ancient phase), they can evolve... view more  Credit: © 2021 KAUST; Anastasia Serin Computer simulations of cells evolving over tens of thousands of generations reveal why some organisms retain a disused switch mechanism that turns on under severe stress, changing some of their characteristics. Maintaining this "hidden" switch is one means for organisms to main...

 E-Mail IMAGE: Computational materials scientists at Ames Laboratory developed an evolutionary algorithm, using a hybrid version of a computer program called Cuckoo Search (CS), which mimics the brood parasite behavior of cuckoo... view more  Credit: U.S. Department of Energy, Ames Laboratory Computational materials science experts at the U.S. Department of Energy's Ames Laboratory enhanced an algorithm that borrows its approach from the nesting habits of cuckoo birds, reducing the search time for new high-tech alloys from weeks to mere seconds. The scientists are investigating a ty...
