德国联邦统计局的初步数据显示，2025 年新生儿数量降至 1946 年以来最低水平。2025 年德国新生儿数约 65.5 万，远低于 1964 年婴儿潮高峰时的 136 万，2024 年的新生儿数据是 68 万。与此同时德国死亡人数接近 101 万，使得 2025 年死亡人数与出生人数之差超过 35.2 万，创战后历史新高。德国出生率连续第四年下降，目前每名妇女平均生育 1.35 个孩子，创历史新低，远低于维持人口稳定所需的 2.1 个孩子。汉堡是唯一一个生育率上升的德国州，2025 年增长了 0.5%。

The Oak Ridge National Laboratory (ORNL) has developed a portable detector that identifies GPS spoofing in real time, including during motion, to help protect transportation systems. Spoofing involves transmitting counterfeit signals that imitate authentic GPS transmissions and produce false information about location, time, or both. GPS jamming, another form of interference, overwhelms receivers with noise and blocks legitimate satellite signals. GPS spoofing overrides real satellite signals to trick a vehicle’s positioning software into following the … More →

瑞士邮件服务商 Proton 利用 2025 年广告竞价数据，分析了逾 54,000 个人口画像，估算广告商为触达不同类美国人所支付的价格。结果显示不同人之间的价格差距远超想象。美国人平均每年产生的广告价值约 1,605 美元；一名居住在蒙大拿州 Bozeman 市、年龄 35-44 岁之间、无子女、用台式机进行高价值企业搜索的男性，其广告价值估计为 17,929.30 美元；一位居住在阿肯色州 Fort Smith 市、年龄在 18-24 岁之间、用 Android 手机进行低价值搜索的父亲，其广告价值仅为 31.05 美元。1,605 美元的平均值与 760 美元的中位数显示，少数高价值用户拉高了平均值，而此类商业模式依赖于高价值用户。分析显示，无子女用户的广告价值比有子女用户平均高出约 17%，一旦某个用户被标记为有子女，针对他们的广告投放会从每次点击 6 美元的财富管理广告转向每次点击 2 美元的面包车和幼儿园广告。台式机用户的价值是 Android 用户的 4.9 倍，苹果 iPhone 用户的价值是 Android 用户的 2.7 倍。用户年龄在 35-44 岁之间时广告价值最高，65 岁后广告价值下降——虽然老年用户价值下降，但针对他们的广告则属于高消费类别如医保补充保险、药品和金融产品。老年人的总体价值降低，但广告商的投放力度更精准。为什么蒙大拿州 Bozeman 市居民的广告价值高？因为大量远程科技工作者的涌入和户外休闲消费使其成为全美竞争最激烈的本地广告市场之一。
