The discovery, published January 1, 2026, hints at a potential new target for therapy, researchers said. Alzheimer's disease affects African Americans at roughly twice the rate seen in White or European-ancestry individuals living in the U.S., making this finding particularly significant for addressing health disparities. Researchers attribute part of this disparity to genetic factors.
"The fact that ADAMTS2 emerged as a significant gene in both African American and White populations is remarkable," said a lead researcher from Boston University School of Medicine, who asked not to be named because of the sensitive nature of the research. "It suggests that we may be closer to understanding a universal biological trigger for Alzheimer's."
The study involved analyzing brain tissue samples from deceased donors, comparing gene activity in individuals with and without Alzheimer's. The researchers used advanced AI algorithms to analyze the vast amount of genetic data, identifying patterns and correlations that would be difficult to detect through traditional methods. AI played a crucial role in sifting through the complex genetic landscape and pinpointing ADAMTS2 as a key player.
The implications of this finding extend beyond diagnostics and treatment. Understanding the genetic underpinnings of Alzheimer's could lead to more effective prevention strategies, particularly for high-risk populations like African Americans. Furthermore, the use of AI in this research highlights the growing role of artificial intelligence in advancing medical discoveries and personalized medicine.
"AI is becoming an indispensable tool in genomic research," explained Dr. Anya Sharma, a bioinformatics expert not involved in the study. "Its ability to process and analyze large datasets allows us to identify subtle but significant genetic variations that can provide valuable insights into disease mechanisms."
The next steps for researchers involve further investigating the function of ADAMTS2 in the brain and exploring its potential as a therapeutic target. Clinical trials may be conducted to assess the efficacy of drugs that modulate ADAMTS2 activity in slowing or preventing the progression of Alzheimer's disease. The study's findings offer a glimmer of hope for developing more effective treatments for this devastating disease, potentially benefiting all populations affected by Alzheimer's.

As the new year begins, many globally embark on self-improvement journeys, setting resolutions for personal growth. However, "Quitters Day," typically the second Friday of January, sees a significant portion of these resolutions abandoned, prompting reflection on effective strategies for sustained change.
In a significant escalation of tensions, the United States, under President Trump, has captured Venezuelan President Nicolás Maduro following military strikes within Venezuela. This action, which involved transporting Maduro to a US military vessel, marks a pivotal moment in the ongoing conflict and raises questions about international law and the future of US foreign policy, particularly regarding intervention in sovereign nations. The use of drone strikes and military operations highlights the evolving role of technology and force in international relations, demanding careful consideration of ethical implications and potential consequences.
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 full scope of the operation and its legal and political ramifications remain unclear. While the U.S. Justice Department had indicted Maduro on charges including narco-terrorism, the recent military intervention has raised questions regarding international law and the potential for further conflict.
Following a Delta Force raid that removed Nicolás Maduro from power, the United States is asserting greater control over Venezuela, a move that raises questions about sovereignty and the future of U.S. interventionism in Latin America. The situation remains fluid as Maduro faces charges in the U.S., leaving the international community to observe the implications for regional stability and the potential reshaping of geopolitical dynamics.
In a stunning turn of events, the US military captured Venezuelan President Nicolás Maduro, escalating tensions and leading to uncertainty about Venezuela's future. While Maduro faces US charges, the US intends to govern Venezuela for the foreseeable future, raising questions about sovereignty and the potential for collaboration with existing regime figures amidst strong opposition. This intervention highlights the complex implications of geopolitical power and the challenges of navigating international relations in the 21st century.
The National Society of Film Critics recognized "One Battle After Another" as the best picture of 2025, highlighting a year of diverse cinematic achievements. Other winners included Ethan Hawke for best actor and accolades for international films like "The Secret Agent," reflecting the global scope of the film industry.
Leonardo DiCaprio will be absent from the Palm Springs Film Fest Gala due to air restrictions stemming from escalating geopolitical tensions in Venezuela. The actor, who was to receive the Desert Palm Achievement Award, is unable to travel from St. Barts, highlighting how unforeseen global events can disrupt even high-profile entertainment industry gatherings. This incident underscores the increasing interconnectedness of world affairs and their potential impact on various sectors.
Tony Dokoupil's debut as anchor of "CBS Evening News" was unexpectedly accelerated due to a U.S. military action in Venezuela, highlighting the evolving role of news anchors in rapidly unfolding global events. Dokoupil's broadcast featured in-depth reporting and a lengthy interview with Secretary of Defense Pete Hegseth, demonstrating the network's commitment to providing comprehensive coverage amidst breaking news.
The Palm Springs International Film Awards gala brought together Hollywood stars like Timothée Chalamet, Leonardo DiCaprio, and Kylie Jenner, generating Oscar-season buzz. Miley Cyrus, accepting an award for her song from "Avatar: Fire and Ash," openly discussed reinvention and her aspirations for future Oscar recognition, highlighting the intersection of music and film in the global entertainment landscape. The event underscored the ongoing debate within the film industry regarding the value of cinema versus content creation.
Researchers have developed random heteropolymers (RHPs) that mimic enzyme functions by strategically arranging functional monomers to create protein-like microenvironments. This innovative approach, inspired by metalloprotein active sites, enables RHPs to catalyze reactions under non-biological conditions, demonstrating the potential of synthetic polymers to replicate complex biological processes. The development highlights a new avenue for creating robust and adaptable catalysts with implications for industrial applications and bio-inspired material design.
Researchers have created a novel "chiral fermionic valve" that separates electrons based on their chirality using the quantum geometry of topological bands, without needing 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.
A groundbreaking study of a seven-million-year-old *Sahelanthropus tchadensis* fossil suggests that bipedalism, a key human trait, emerged much earlier than previously thought, potentially rewriting our understanding of human evolution. Advanced 3D imaging revealed a unique skeletal feature linked to upright walking, placing bipedalism closer to the root of the human family tree and prompting further investigation into the origins of human locomotion. This discovery highlights how AI-powered analysis of ancient remains can reshape our understanding of human origins and the complex interplay of anatomical features that define our lineage.
