James Joyce's tome 'Finnegans Wake' famously breaks the rules of normal prose through its unusual, dreamlike stream of consciousness, and new work in chaos theory takes a closer look at how Joyce's challenging novel stands out mathematically. Researchers compared the distribution of punctuation marks in various experimental novels to determine the underlying order of 'Finnegans

Engineering researchers have successfully developed a quantum microprocessor chip for molecular spectroscopy simulation of actual large-structured and complex molecules. Quantum simulation enables scientists to simulate and study complex systems that are challenging or even impossible using classical computers across various fields, including financial modelling, cybersecurity, pharmaceutical discoveries, AI and machine learning. For instance, exploring molecular

A new adaptive 3D printing system can identify the positions of randomly distributed organisms and safely move them to specific locations for assembly. A first-of-its-kind adaptive 3D printing system developed by University of Minnesota Twin Cities researchers can identify the positions of randomly distributed organisms and safely move them to specific locations for assembly. This

Scientists have developed photoresponsive supramolecular polymers that can undergo both intrachain folding and interchain aggregation. The material properties of polymers are determined by the competition between polymer chain folding and aggregation. For the first time, researchers from Japan developed folded supramolecular polymers that can spontaneously undergo interchain aggregation. Using atomic force microscopy, they revealed that

Researchers develop a one pot process to transform aromatic ketones to esters, offering advancements in pharmaceutical synthesis and materials science. Aromatic ketones have traditionally been underutilized in cross-coupling reactions due to the difficulty in breaking their tough C-C bonds. Researchers have now introduced a novel method that overcomes this challenge by transforming aromatic ketones into

Researchers have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from the black hole surroundings. The radiation originates from the combined effect of the chaotic movements of magnetic fields and turbulent plasma gas. Researchers at the University of Helsinki have succeeded in something that has been pursued since the

High-resolution images show large spots on the surface of Polaris. Researchers using Georgia State University's Center for High Angular Resolution Astronomy (CHARA) Array have identified new details about the size and appearance of the North Star, also known as Polaris. The new research is published in The Astrophysical Journal. Earth's North Pole points to a

Scientists have developed a model capable of predicting the cycle lives of high-energy-density lithium-metal batteries by applying machine learning methods to battery performance data. The model proved able to accurately estimate batteries' longevity by analyzing their charge, discharge and voltage relaxation process data without relying on any assumption about specific battery degradation mechanisms. The technique

Finding the next groundbreaking polymer is always a challenge, but now researchers are using artificial intelligence (AI) to shape and transform the future of the field. Nylon, Teflon, Kevlar. These are just a few familiar polymers -- large-molecule chemical compounds -- that have changed the world. From Teflon-coated frying pans to 3D printing, polymers are

Today, many commercial tools claim to be highly successful at detecting machine-generated text, with up to 99% accuracy, but are these claims too good to be true? RAID, the Robust AI Detection benchmark, which shows that most detectors are easily fooled, setting a new bar for AI detection to clear. Machine-generated text has been fooling

When a global pandemic forced previous a graduate student out of the lab and onto the computer, he found a world of difference hidden in the long-studied species of Botryoccocus braunii -- and discovered that it isn't one species at all, but three. When a global pandemic forced previous graduate student Devon Boland, Ph.D., out

The design of streets and layout of buildings have an impact on a city's resilience in the face of increasingly severe floods brought on by climate change. Researchers look at buildings and other urban structures as physicists consider elements in complex material systems. With this insight, the researchers have developed a new approach to urban
