Artificial intelligence leaders are considering building data centers in space due to concerns about the increasing energy and land requirements of these facilities on Earth. The concept, once relegated to science fiction, is gaining traction as a potential solution to the escalating demands of AI computing.
Google announced in November its Project Suncatcher, a space data center initiative slated for test launches in 2027. Elon Musk stated at a recent conference that space data centers could become the most cost-effective method for training AI within five years. Support for the idea also comes from Jeff Bezos, founder of Amazon and Blue Origin; Sam Altman, CEO of OpenAI; and Jensen Huang, CEO of Nvidia.
Data centers are the massive computing facilities that power AI, requiring vast amounts of electricity and physical space. As AI models grow in complexity, so does the demand for these resources. The concern is that Earth may not be able to sustainably support the continued expansion of data centers. Building these facilities in space could alleviate these pressures by tapping into the abundant solar energy available and utilizing the vacuum of space for cooling.
The implications of space-based data centers extend beyond resource management. They could potentially revolutionize data transmission speeds and reduce latency, enhancing the performance of AI applications. However, the endeavor also presents significant technological and economic challenges. The cost of launching and maintaining data centers in space is substantial, and ensuring their reliability in the harsh space environment is a major hurdle.
The concept also raises questions about the environmental impact of space launches and the potential for space debris. Furthermore, the visibility of these data centers in the night sky, as envisioned by some proponents, could raise concerns about light pollution and the aesthetic impact on astronomical observations.
Project Suncatcher's planned test launches in 2027 represent a crucial step in assessing the feasibility of space-based data centers. The project aims to evaluate the performance of computing hardware in space and to develop efficient cooling systems. The success of these early tests will likely determine the future trajectory of this ambitious endeavor.

Aspirations to reduce meat consumption, prominent in the 2010s due to health, ethical, and environmental concerns, have waned, with plant-based meat sales declining despite initial investment and public interest. This shift suggests a change in consumer priorities, as evidenced by the rise of alternative diets and a renewed focus on traditional meat consumption.
Drawing from multiple news sources, Menemsha Films has acquired North American distribution rights to "Ethan Bloom," a coming-of-age interfaith comedy directed by Herschel Faber, starring Joshua Malina, Rachelle Lefevre, and introducing Hank Greenspan as a Jewish boy who feels a calling to the Catholic church. The film, which also features Caroline Valencia, will premiere at film festivals before a theatrical release, aiming to connect with audiences through its exploration of adolescence and identity.
China's box office rebounded in 2025, surpassing $7.4 billion, driven by a surge in animated films and franchise sequels. This recovery highlights the potential of AI-driven animation techniques to create compelling content and the enduring power of established intellectual property in attracting audiences, signaling a shift in entertainment consumption patterns.
Netflix experimented with a limited theatrical release for the "Stranger Things" finale, allowing fans to experience the highly anticipated conclusion on the big screen. This event-ized screening at locations like Hollywood's Egyptian Theater created a communal viewing experience, highlighting the evolving ways streaming content engages with audiences and potentially reshaping release strategies.
James Cameron's "Avatar: Fire and Ash" dominated the New Year's Eve box office, signaling continued success for the franchise acquired by Disney, with projections indicating it will soon surpass $1 billion globally. Despite this film's strong performance, overall domestic ticket sales in the US and Canada for 2025 reached $8.9 billion, a slight increase over the previous year but still falling short of pre-pandemic levels and industry expectations, reflecting ongoing challenges for the cinema business.
Researchers have developed random heteropolymers (RHPs) that mimic enzyme functions by strategically positioning functional 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-like materials with potential applications in diverse fields.
Researchers have created a novel "chiral fermionic valve" that spatially separates electrons based on their chirality using the quantum geometry of topological bands, achieving this without magnetic fields. This innovative device, made from single-crystal PdGa, demonstrates the quantum interference of chiral currents, opening new possibilities for advanced electronic and spintronic devices.
In 2026, expect to see smaller, more efficient AI models challenging large language models in reasoning capabilities, alongside advancements in gene editing clinical trials for rare diseases. A sample collection mission from Phobos and the impact of Trump-era US policy changes on the scientific community are also key developments to watch.
High-resolution images captured by the CHARA Array reveal that novae are complex, multi-stage stellar explosions, challenging previous assumptions of simple blasts. These observations show colliding gas streams and delayed eruptions, generating shock waves that produce intense gamma rays and providing visual confirmation of existing theories. This discovery impacts astrophysics by redefining our understanding of stellar evolution and explosive phenomena in the cosmos.
A new study reveals that even a single alcoholic drink daily can significantly elevate the risk of mouth cancer, particularly when combined with chewing tobacco. Researchers found a 50% increased risk with just one standard drink, highlighting the dangers of even light alcohol consumption and its synergistic effect with other carcinogenic habits.
Research indicates that a decline in the protein platelet factor 4 contributes to immune system aging by causing blood stem cells to multiply excessively and become prone to mutations linked to diseases. Restoring platelet factor 4 in studies involving older mice and human stem cells rejuvenated aging blood and immune cells, suggesting a potential therapeutic target for age-related immune decline. These findings highlight the importance of maintaining healthy protein levels for a robust immune response as we age.
