全球暖化可能导致城市鼠患

一项对 16 个主要城市的研究发现,全球变暖正在帮助老鼠在世界各大城市茁壮成长,平均气温上升最快的地区,老鼠的数量增长也最快。直接估算一个城市的老鼠数量极其困难,弗吉尼亚州里士满大学的研究人员通过查看城市记录在案的老鼠投诉数量,了解老鼠种群的变化情况。他们获得了13 个美国城市以及东京、阿姆斯特丹和多伦多的数据。分析表明,美国新奥尔良、路易斯维尔和日本东京的老鼠数量正在下降,达拉斯和圣路易斯的老鼠数量保持稳定,而其他 11 个城市的老鼠数量正在上升,其中华盛顿特区、旧金山、多伦多、纽约和阿姆斯特丹的老鼠数量增长最快。研究发现,老鼠数量增长与平均气温上升的关系最为密切,其次是根据卫星照片评估的城市化程度,然后是人口密度,城市的 GDP 与老鼠数量的趋势没有明显关联。

WhatsApp, a rival messaging platform, introduced some measures to counter disinformation when Covid-19 was first sweeping the world. The regulator said it had received information that messages containing stock tips and other investment advice with respect to selected listed companies are being widely circulated through websites and social media platforms such as Telegram, Facebook, WhatsApp and Instagram. The regulator said it has been undertaking several campaigns to educate the investors to be vigilant while taking investment decisions based on stock tips. Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. For Oleksandra Tsekhanovska, head of the Hybrid Warfare Analytical Group at the Kyiv-based Ukraine Crisis Media Center, the effects are both near- and far-reaching.
