Core Viewpoint - The article highlights the increasing sophistication and variety of scams targeting the elderly, particularly in the context of investment and financial schemes, emphasizing the need for awareness and protective measures against these fraudulent activities [1][6]. Group 1: Types of Scams - **Scam Type One: Technology Concept Packaging** Fraudsters exploit elderly individuals' lack of understanding of concepts like "blockchain," "digital currency," and "metaverse," presenting them as low-risk, high-return investment opportunities. These schemes often turn out to be Ponzi schemes, where returns for earlier investors are paid using the capital from new investors, leading to total loss when funds dry up [2]. - **Scam Type Two: AI Deception Techniques** Scammers utilize AI technology to create convincing fake news and emotional appeals. They produce fabricated policies that mislead the elderly, create AI-generated personas to gain trust, and even use deepfake technology to impersonate loved ones, facilitating targeted scams [3]. - **Scam Type Three: High-Interest Investment Traps** Fraudsters lure elderly individuals with promises of high returns, often without any legitimate financial licenses. Common tactics include fabricating government endorsements, conducting misleading site visits, and ultimately disappearing with the funds after initial payouts [4]. - **Scam Type Four: "Free Benefits" Bait** Scammers use the allure of free gifts or services to draw in elderly victims, leading to subsequent scams or illegal fundraising. This includes offering free products, travel, health check-ups, or seminars that ultimately serve as platforms for selling fraudulent investment opportunities [5]. Group 2: Recommendations for Prevention - The article stresses the importance of elderly individuals enhancing their awareness of scams, remaining skeptical of offers that seem too good to be true, and consulting trusted sources when in doubt. It also calls for collective efforts from families and communities to strengthen anti-fraud education and improve regulatory oversight in the elder care sector [6].

微导管是一种医疗器件，可沿人体血管蜿蜒穿行，用于治疗动脉阻塞、止血，甚至阻断肿瘤供血或实施 精准化疗。然而，目前医生在操作中仍需借助导丝，小心推动微导管在血管中行进，这一过程不仅费 时，还可能损伤血管壁。更关键的是，现有导丝与微导管尺寸偏大，难以抵达大脑深处直径小于150微 米、细如发丝的微小血管。MagFlow的尺寸仅为常规导管的一半，能借助血流动能行进，从而最大限度 减少与血管壁的接触。 MagFlow的主体由两片黏合聚合物构成，可"像消防软管一样"自如膨胀，便于输送稀薄或黏稠的生物医 用液体。团队还同步开发了机器人转向平台"OmniMag"，通过安装在机械臂上的磁场发生器引导微导管 行进。该平台能够根据医生的触控移动，自动计算出引导MagFlow磁性尖端转向所需的最佳磁场方向。 在验证实验中，团队将MagFlow置入猪的头部、颈部和脊柱中极为狭窄且弯曲的动脉，快速安全输送了 造影剂和栓塞剂，充分展示了其独特性能。 研究团队表示，这一成果将"流驱动导航"概念转化为可行的临床方案，未来有望为心血管疾病治疗开辟 新途径，用于治疗出血性中风、动静脉畸形的成年患者，以及患有癌症的儿童。 来源：科技日报 科技日报记 ...
