In a groundbreaking study, researchers from Rice University have introduced an exciting new class of quantum critical metal, fundamentally enhancing our understanding of electron interactions within quantum materials. Spearheaded by Qimiao Si, a prominent figure in the field of physics, the research was recently published in *Physical Review Letters*. The work particularly focuses on the
Japan’s geographical position on the Pacific Ring of Fire renders it particularly susceptible to seismic activity, making it one of the most earthquake-prone countries globally. The region faces the subtle yet persistent occurrence of thousands of minor earthquakes annually, alongside the looming possibility of catastrophic events often referred to as “the big one.” While accurately
The Citarum River, notorious for being one of the most polluted rivers in Indonesia, runs through the heart of an urbanized landscape struggling with the impacts of rapid development and environmental degradation. Historically, this river has been vital for local communities, providing resources for fishing, irrigation, and as a water source. However, the escalating pollution
Neutron stars and black holes represent the ultimate boundaries of matter and gravitational phenomena in our universe. These cosmic entities challenge our understanding of physics, particularly within the realms of quantum chromodynamics and general relativity. While they are often compared due to their extreme conditions, their fundamental properties and behaviors diverge sharply when examined closely.
The evolution of workplace safety technology continues to advance, with notable innovations aimed at mitigating physical strain on workers. A groundbreaking project at the University of Michigan has introduced the concept of knee exoskeletons, designed with commercial knee braces and drone propulsion systems. This novel technology possesses the potential to combat fatigue during lifting and
In recent years, glucagon-like peptide-1 (GLP-1) receptor agonists such as Ozempic and Mounjaro have emerged as groundbreaking solutions for managing type 2 diabetes and aiding in weight loss. These medications have gained immense popularity due to their effectiveness, creating a surge in demand from both those requiring medical intervention and individuals seeking quick weight loss
The global drive towards sustainable industrial practices has intensified research efforts focused on the conversion of biomass into essential chemical precursors, such as olefins. These precursors serve as building blocks for various products, from plastics to pharmaceuticals. A recent study from Kyushu University has highlighted a novel approach using a zeolite material known as Na-ZSM-5,
The recent arrival of a cargo spacecraft at the International Space Station (ISS) was expected to bolster the station’s supplies. However, the uncrewed Russian vessel, Progress 90, brought with it an unanticipated element—an unusual and unpleasant odor that caught astronauts off-guard. As they opened the hatch to receive food, water, hygiene products, and scientific materials,
Our everyday conversations can often include moments where we struggle to retrieve the right word, a phenomenon known as “lethologica.” It is particularly common among older individuals, who may experience these lapses more frequently than their younger counterparts. Such struggles are typically dismissed as normal aging; however, research has raised concerns that they could indicate
The Milky Way has long been regarded as a vital reference point for the study of galactic formation and evolution. Nested within this galaxy, astronomers utilize state-of-the-art telescopes to delve into its intricacies, leveraging an array of wavelengths to discern its stellar composition, gas dynamics, and various other factors. This in-depth scrutiny, while enlightening, offers
In an unprecedented achievement, physicists at Oak Ridge National Laboratory have harnessed the power of the Frontier supercomputer to execute the largest astrophysical simulation in history. Completed in November 2024, this simulation—named ExaSky—utilized a staggering 9,000 computing nodes to analyze a volume of the expanding Universe greater than 31 billion cubic megaparsecs. This milestone is
