In a paper published in Science Bulletin, Researchers discovered a unique signature of the planar Hall effect (PHE) in magnetic Weyl semimetals, where PHE conductivity is determined by a global quantity: the Chern number of Weyl point. Due to the robustness of the Chern number, the PHE conductivity here is independent of many material details, leading to a planar Hall plateau, which is rare and has great potential applications. By revealing completely new physical signatures, their work significantly advances the field of Hall transport.
Researchers from Trinity College Dublin have collaborated with international partners to explore if societal inequality affects our brain. Their research paper is published in Nature Aging today, Friday, December 27, by an international team of researchers from the Multipartner Consortium to expand dementia research in Latin America (ReDLat), the Latin American Brain Health Institute (BrainLat), the GIobal Brain Health Institute (GBHI) at Trinity College Dublin, and other centres across the globe. The study reveals a direct link between structural inequality—such as socioeconomic disparities measured by a country-level index (GINI)—and changes in brain structure and connectivity associated with aging and dementia.
The study also sheds light on how societal inequities become biologically embedded, particularly in underrepresented populations across Latin America and the United States.
Quantum technology jointly developed at Nanyang Technological University, Singapore (NTU Singapore) and the National University of Singapore (NUS) has now been spun off into a new deep tech startup, AQSolotl.
The startup’s flagship product, CHRONOS-Q, is a quantum controller that acts as a translator between conventional computing systems and quantum computers.
Developed by university researchers affiliated with Singapore’s Centre for Quantum Technologies (CQT), it enables users to control quantum computers easily and efficiently using their laptops and desktop computers.
Unlike traditional computers that operate on a binary system of 1s and 0s, quantum computers utilise the principles of quantum mechanics to achieve vastly superior computational capabilities.
Quantum computers will solve problems once considered unsolvable by conventional computers, opening new possibilities in fields like cryptography, advanced simulations and AI. They are theorised to be many thousands of times more powerful than today’s fastest silicon processors for some complex computational tasks.
The proprietary quantum controller technology, developed and refined over three years, is currently being piloted at CQT as part of the hardware setup for the National Quantum Computing Hub and NTU’s Nanyang Quantum Hub.
