来源：环球网 【环球网科技综合报道】1月2日消息，据《卫报》报道，由于销量不佳，苹果公司被迫削减了 Vision Pro 头显的产量，该公司曾希望这款头显能够开启"空间计算"的新时代。 Sensor Tower 的数据显示，这家科技公司去年还将 Vision Pro 的营销支出减少了 95% 以上。苹果公司尚 未公布该设备的销售数据，但IDC估计，该设备去年第四季度仅售出 4.5万台。 外媒称，Vision Pro 的明显失败让人想起 2013 年命运多舛的谷歌眼镜。尽管遭遇这些挫折，科技公司仍 在坚持研发智能眼镜。比如Meta 上个月证实，它正在"将部分投资从元宇宙转移到人工智能眼镜和其他 可穿戴设备"。 外媒还表示，苹果已暂停其下一代虚拟现实产品的研发计划，转而专注于可穿戴人工智能设备。（思 瀚） ...

来源：科技日报 在自然界的奇迹中，定向导航或许是最令人惊叹的能力之一。比如身长仅12厘米的阿尔卑斯蝾螈出生在 小水洼或溪流中，成年后便隐入欧洲茂密的森林。然而，当繁衍的使命召唤时，它们竟能从42公里外的 地方出发，沿直线准确无误地回到出生地。这种惊人的定向能力并非偶然，而是源于一种人类才刚刚开 始窥探的"超级感官"——磁感受作用。地球磁场像一张无形的网，紧紧包裹着这颗行星。对人类而言， 磁场是个抽象的物理概念，但对许多动物来说，它既是精准的指南针，也是全天候的GPS。西班牙研究 员迭戈-拉西利亚指出，这种感官极为神秘，因为它不像嗅觉或听觉那样拥有显而易见的器官。 科学家发现，动物导航不仅需要"指南针"辨别南北，更需要一张"内在地图"确定位置。阿尔卑斯蝾螈便 是这方面的高手。这些夜间迁徙者，每天黄昏时分都会进行一次"系统校准"，利用磁场微调自身内在地 图的位置。每天日落时，它们会根据磁场微调方向，选择磁场干扰最少的时刻出发。换句话说，它们是 用磁场参考来更新内在的空间认知。 那么，动物究竟是如何感知这些隐形线条的？目前，科学界发现了3种并行的神奇机制。 第一种与奇妙的量子效应有关。德国科学家发现，在知更鸟等候鸟 ...

Core Viewpoint - A joint team from the University of Edinburgh and NVIDIA has developed a new method to compress the memory required for AI models, enhancing their accuracy in complex tasks while maintaining response speed and significantly reducing energy consumption [1][4]. Group 1: Memory Compression Technique - The team discovered that compressing the memory used by large language models (LLMs) to one-eighth of its original size improved performance in specialized tests, such as mathematics, science, and programming, without extending inference time [4]. - This memory compression technique, named "Dynamic Memory Sparsification" (DMS), allows AI models to dynamically determine which tokens are essential for subsequent reasoning and which can be discarded, enabling deeper "thinking" within the same computational resources [4][6]. Group 2: Performance Improvements - In tests based on the American Mathematics Olympiad qualification exam (AIME 24), the compressed model scored an average of 12 points higher than the uncompressed model under the same memory read conditions [5]. - The compressed model also outperformed the original model in a professional science question bank created by PhD-level experts and improved its average score by 10 points on a platform assessing coding abilities [5]. Group 3: Implications for AI Development - The DMS memory compression technique challenges the conventional belief that more computational resources lead to stronger AI, suggesting a paradigm shift towards lightweight, high-performance AI [6]. - This approach aligns with human cognitive processes, emphasizing selective memory and key information extraction, which may accelerate the development of general AI [6].

Core Insights - Apple has deprioritized the Mac Pro, indicating that there will be no significant updates planned for 2026, effectively replacing it with the more compact Mac Studio [1] - The performance gap between Mac Studio and Mac Pro is widening, with the upcoming M5 Ultra chip exclusively for Mac Studio, leaving Mac Pro behind [4] Group 1 - Apple has internally "basically given up" on the Mac Pro product line, with no major updates expected in 2026 [1] - The Mac Studio, equipped with the M3 Ultra chip, has already surpassed the Mac Pro in performance, supporting more CPU and GPU cores, and offering a maximum storage capacity of 16TB compared to Mac Pro's 8TB [4] - Mac Studio's unified memory limit is 512GB, which is more than double that of Mac Pro's 192GB, and it can support four 8K displays versus Mac Pro's three [4] Group 2 - The Mac Pro has faced challenges in meeting professional desktop user needs, with its initial 2013 design criticized for sacrificing cooling performance, leading to its market failure [5] - The 2019 modular Mac Pro regained some trust among professional users but has since struggled with its positioning in the Apple Silicon era [5]

Core Viewpoint - The European Space Agency (ESA) confirmed a cyberattack on its external servers, stating that it has initiated an investigation and enhanced cybersecurity measures, with no sensitive internal data reported as leaked [1][4]. Group 1: Cybersecurity Incident - The cyberattack was first disclosed by a hacker known as "888" on an underground forum, claiming to have stolen over 200GB of data, including unpublished Bitbucket source code, CI/CD pipeline configurations, API keys, and internal documents [4]. - ESA clarified that the incident only affected a "very small" number of external servers, which are primarily used to support collaborative engineering projects within the scientific community, and that core confidential information was not compromised [4]. Group 2: Previous Incidents - It is noteworthy that a similar cybersecurity incident occurred last year, where ESA's official merchandise website was compromised by hackers who implanted malicious JavaScript to create a fake Stripe payment page, attempting to deceive users into entering credit card information [4].
