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。

Also in the latest update is the ability for users to create a unique @username from the Settings page, providing others with an easy way to contact them via Search or their t.me/username link without sharing their phone number. Telegram has gained a reputation as the “secure” communications app in the post-Soviet states, but whenever you make choices about your digital security, it’s important to start by asking yourself, “What exactly am I securing? And who am I securing it from?” These questions should inform your decisions about whether you are using the right tool or platform for your digital security needs. Telegram is certainly not the most secure messaging app on the market right now. Its security model requires users to place a great deal of trust in Telegram’s ability to protect user data. For some users, this may be good enough for now. For others, it may be wiser to move to a different platform for certain kinds of high-risk communications. Friday’s performance was part of a larger shift. For the week, the Dow, S&P 500 and Nasdaq fell 2%, 2.9%, and 3.5%, respectively. Pavel Durov, Telegram's CEO, is known as "the Russian Mark Zuckerberg," for co-founding VKontakte, which is Russian for "in touch," a Facebook imitator that became the country's most popular social networking site. Messages are not fully encrypted by default. That means the company could, in theory, access the content of the messages, or be forced to hand over the data at the request of a government.
