It was an interesting week for physics research as a team from the Austrian Academy of Sciences unveiled a new approach to the study of entanglement that they say could significantly improve the understanding of entanglement in quantum materials. A South Korean team made headlines around the world earlier this year by claiming that the polycrystalline compound LK99 was superconducting at room temperature. Now, a small team from the National Laboratory for Condensed Matter Physics and the Beijing Institute of Physics has provided strong evidence that LK-99 is not a superconductor, refuting previous claims. And those responsible for the JT-60SA, currently the world’s largest experimental nuclear fusion reactor, announced that the facility had been officially opened: installed in a hangar in Naka, Japan, the six-story machine uses a tokamak in donut shape to study the feasibility. to use fusion as an energy source.
In tech news, a Google team tricked ChatGPT into leaking users’ private data using a few simple commands. And a small team of mechanical engineers from the Universidad Tecnológica de Panamá developed an insulating material based on rice husk and, after evaluating its thermal and mechanical properties, suggested that it could be the eco-friendly insulating material of future. A combined team of robotics engineers from the Norwegian University of Science and Technology and the Indian Institute of Technology Bombay have developed a sensing leg that could be used to improve the ability of legged robots to move on different land. And another combined team, this one made up of members from the University of Washington and MIT, developed a new approach to teaching robots to perform desired tasks, allowing them to learn in a changing environment using both both exploration and human feedback.
Separately, a team of medical researchers from Monash University, working with colleagues from the University of Western Australia and the University of Iowa, found evidence that high levels of “good” cholesterol may be associated with a risk of developing dementia. Additionally, NASA announced that after 50 years, the United States will attempt to land on the Moon on January 25, with liftoff scheduled for December 24. Finally, a team from Wake Forest University School of Medicine has found evidence that human behavior is guided by rapid changes in dopamine levels in the brain.
