A powerful earthquake in Chile defied expectations. The magnitude 7.4 quake struck northern Chile near Calama in July 2024. Scientists now believe a hidden, deep-seated force supercharged the event.
The quake originated deep within the Earth. It tore through unexpectedly hot rock layers. This triggered a rare chain reaction, accelerating the rupture. The University of Texas at Austin led the research. Their findings challenge long-held assumptions about deep earthquakes.
The shaking damaged buildings and disrupted power. The earthquake's unusual strength surprised experts. It highlights the complexity of seismic activity.
Chile is earthquake-prone. In 1960, it experienced the largest earthquake ever recorded. That magnitude 9.5 event caused a devastating tsunami.
Researchers are now studying the implications. Understanding this new heat-driven force is crucial. It could improve future earthquake predictions. This discovery may reshape our understanding of deep-earth processes.

Amidst a shifting media landscape, CBS Evening News is set to premiere a revamped nightly newscast anchored by Tony Dokoupil, guided by five core principles, including an unapologetic declaration of love for America. This move, under the oversight of Bari Weiss, signals a potential shift in the network's approach to news presentation, reflecting broader debates about objectivity and national identity in journalism.
Films garnering awards season attention are breaking cinematic taboos by portraying the complex and often difficult realities of motherhood, sparking global conversations about societal expectations and parental sacrifices. These narratives, reflecting diverse cultural backgrounds, challenge conventional portrayals of mothers and invite international audiences to consider the ethical dilemmas inherent in parenting.
Dick Clark's New Year's Rockin' Eve with Ryan Seacrest achieved its highest viewership in four years, drawing over 30 million viewers at its peak during the Times Square ball drop. The program, a long-standing cultural tradition in the United States, continues to dominate New Year's Eve broadcasts, surpassing competing specials from CBS and CNN. This reflects the enduring appeal of large-scale, shared celebratory events in a media landscape increasingly fragmented by streaming and on-demand content.
Andre Gaines' adaptation of Amiri Baraka's "Dutchman" grapples with race and identity in a modern context, yet its fidelity to the source material limits its ability to offer a fresh perspective. While the film incorporates contemporary elements, it struggles to fully realize its potential as an updated interpretation of the influential play.
Researchers have developed random heteropolymers (RHPs) that mimic enzyme functions by strategically arranging monomers to create protein-like microenvironments. This innovative approach, inspired by metalloprotein active sites, enables the RHPs to catalyze reactions under non-biological conditions, demonstrating a novel method for creating robust enzyme mimics with potential applications in various fields.
Researchers have created a novel "chiral fermionic valve" that separates electrons based on their chirality using the quantum geometry of topological bands, eliminating the need for magnetic fields. This innovative device, made from single-crystal PdGa, spatially separates chiral currents with opposite orbital magnetizations, demonstrating quantum interference and opening new possibilities for advanced electronic devices.
In 2026, expect advancements in small-scale AI models challenging large language models, gene editing clinical trials for rare disorders, and a sample collection mission from Phobos.

The James Webb Space Telescope has detected a bizarre exoplanet, PSR J2322-2650b, challenging existing planetary formation theories with its carbon-rich atmosphere, potential diamond core, and distorted shape caused by the extreme gravity of its neutron star host. This Jupiter-mass world, orbiting in under eight hours, presents a unique opportunity to study planetary evolution under extreme conditions and expands our understanding of the diversity of celestial bodies.
Researchers have identified the ADAMTS2 gene as significantly more active in Alzheimer's patients, regardless of race, suggesting a common biological pathway for the disease. This discovery, stemming from a study focused on African Americans who are disproportionately affected by Alzheimer's, offers a promising new avenue for developing targeted treatments.
Atypical deep earthquakes, usually less impactful due to hotter, less brittle rock, can be surprisingly powerful, as demonstrated by a recent Chilean quake; research suggests a unique heat-driven chain reaction accelerated the rupture, challenging existing seismic models and potentially improving future risk assessments. This finding highlights the complex interplay of geological factors in earthquake dynamics, prompting further investigation into deep-seated seismic events and their societal impact.
A recent study from Virginia Tech dispels the myth that the body compensates for increased physical activity by reducing energy expenditure in other areas. Researchers discovered that exercise directly increases total daily calorie burn without triggering metabolic slowdown, confirming the additive benefits of movement. This finding has significant implications for understanding the true impact of exercise on overall energy balance and health.
Amidst escalating tensions following U.S. airstrikes on Iranian nuclear sites, President Trump has pledged support for Iranian protesters, prompting a sharp rebuke from Tehran warning against foreign interference. The protests, triggered by economic woes and echoing the 2022 Mahsa Amini demonstrations, highlight internal pressures within Iran and further strain the already volatile relationship between the two nations. The international community is watching closely as these events unfold, mindful of the potential for regional instability.
