Science News from research organizations Something hidden deep underground supercharged this Chile earthquake Date: January 1, 2026 Source: University of Texas at Austin Summary: A powerful 7.4-magnitude earthquake struck northern Chile in July 2024and it wasnt supposed to be that strong. Unlike Chiles infamous shallow megathrust quakes, this one ruptured deep inside the Earth, where shaking is usually weaker at the surface.
Researchers discovered that the quake broke long-held assumptions by tearing through hotter rock layers than expected, fueled by a rare chain reaction that accelerated the rupture.

As the new year begins, many globally embrace the tradition of New Year's resolutions, yet a significant portion abandon these goals by "Quitter's Day," highlighting a universal struggle with self-improvement. This phenomenon underscores the challenge of translating aspirations into tangible change, a concept deeply rooted in modern society's pursuit of progress.
In a significant escalation of tensions, the United States, under President Trump, has captured Venezuelan President Nicolás Maduro in a military operation involving strikes within Venezuela. This action, following months of rising conflict and covert operations like drone strikes, raises questions about the future of US-Venezuelan relations and the implications of such interventions for international sovereignty and stability. The event highlights the increasing role of AI in military strategy and the ethical considerations surrounding its deployment in foreign policy.
Following U.S. strikes on Caracas, Venezuelan President Nicolás Maduro was arrested and faces criminal charges in the U.S. This action marks a significant escalation of President Trump's pressure campaign against Venezuela, though the legal, political, and military ramifications remain unclear. The U.S. Justice Department has sought Maduro's extradition since his 2020 indictment on charges including narco-terrorism.
Following a Delta Force raid and the removal of Nicolás Maduro, the United States is asserting greater control over Venezuela, signaling a potential shift in the country's leadership and direction. This intervention raises questions about sovereignty, international law, and the future of U.S.-Venezuelan relations amidst existing tensions over drug trafficking and political legitimacy.
In a stunning turn of events, the US has captured Venezuelan President Nicolás Maduro in a military operation, escalating tensions and raising questions about the future of Venezuela. While Maduro faces charges in the US, the political landscape in Venezuela is uncertain, with the US asserting control and the existing regime rejecting foreign intervention. This situation highlights the complex implications of international relations and power dynamics in the 21st century.

Researchers have developed random heteropolymers (RHPs) that mimic enzyme functions by strategically positioning functional monomers to create protein-like microenvironments. This innovative approach, guided by metalloprotein analysis, allows for the creation of catalysts that function under non-biological conditions, showcasing the potential of AI-driven material design to revolutionize industrial and environmental applications.
Researchers have created a novel "chiral fermionic valve" that separates electrons based on their chirality using the quantum geometry of topological bands, without the need for magnetic fields. This innovative device, made from single-crystal PdGa, spatially separates currents with opposite chiralities, demonstrating quantum interference and opening new possibilities for electronic devices.
New research from Rutgers University reveals that the brain coordinates fast, reactive processes with slower, more reflective thought by using distinct internal clocks in different regions. These regions communicate via white matter connections, and the efficiency of this timing system may determine cognitive abilities, highlighting the brain's complex synchronization mechanisms. This discovery offers insights into variations in cognitive performance and the fundamental processes underlying human thought.
