特朗普称正考虑暂停征收联邦汽油税
特朗普称正考虑暂停征收联邦汽油税2026年9月，麻省理工学院团队展示一种可在胃肠道环境中逐步分解的微型电池，面向需要供电的可吞服电子设备。电池使用镁和三氧化钼作为电极，并配合可吸收的凝胶电解质，输出电压达到1.84伏。研究人员制作了直径7.5毫米的圆片和长24毫米的条形版本，以适应不同装置。
在模拟胃液的酸性溶液中，电池可正常工作约三天，之后性能逐渐下降，并在数周内完全分解。团队还把它用于胃内无线识别标签，以及通过微弱电流刺激胃部的实验胶囊，验证其供电能力。研究目标是减少传统电池外壳损坏时的材料风险，并降低排出后对环境的影响。可分解设计也有利于设备保持独立运行，减少对外部供电的依赖。不过，电池材料的选择、剂量和分解速度需要与具体使用场景匹配。当前结果属于新型电源和器件研究，不能据此认为普通电池可以安全吞服，或相关装置已可直接用于临床。
