澳大利亚鹦鹉学会开饮水器喝水

科学家发现,在澳大利亚悉尼西部的郊区,一群凤头鹦鹉学会了操作人类使用的饮水器,并通过一系列复杂的旋转和按压动作,将水流引入嘴中。这种行为在其他任何鸟类中都未曾被观察到,并且正在悉尼西部的凤头鹦鹉种群中传播。研究人员在一台饮水器附近安装了两台动作感应相机。在超过一个月的时间里,相机记录下了近 14 小时凤头鹦鹉围绕饮水器活动的画面。研究人员从中识别出了 525 次不同的饮水尝试。每只凤头鹦鹉在具体操作方式上略有不同,但总体策略一致:它们会用一只或两只脚踩住饮水器的旋转把手,然后降低身体重量以顺时针方向旋转把手,并防止其弹回原位。当水流从出水口涌出时,鹦鹉便低头啜饮。那么,在已经有水坑、溪流等自然水源的情况下,为什么这些凤头鹦鹉会选择去使用饮水器呢?研究人员推测,也许它们偏爱饮水器提供的更为纯净的水源,抑或是饮水器较高的位置有助于它们观察是否有鹰隼等捕食者接近。

Telegram Gives Up On Crypto Blockchain Project

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”

The lead from Wall Street offers little clarity as the major averages opened lower on Friday and then bounced back and forth across the unchanged line, finally finishing mixed and little changed.The Dow added 33.18 points or 0.10 percent to finish at 34,798.00, while the NASDAQ eased 4.54 points or 0.03 percent to close at 15,047.70 and the S&P 500 rose 6.50 points or 0.15 percent to end at 4,455.48. For the week, the Dow rose 0.6 percent, the NASDAQ added 0.1 percent and the S&P gained 0.5 percent.The lackluster performance on Wall Street came on uncertainty about the outlook for the markets following recent volatility.
