>Billionaire seeks date
Having recently split up with his girlfriend, Japanese billionaire Maezawa has launched an online appeal for a female "life partner" to accompany him on SpaceX's maiden tourist voyage - a slingshot trip around the moon tentatively scheduled for 2023.
Writing on his website, the fashion mogul said he thought the lunar trip was a good chance to "seriously face up to idea of 'continuing to love one woman' which I'd only really had a hazy image about."
According to the conditions listed on the website, applicants must be single women aged 20 or over, with a "bright personality" and always positive, have an interest in going to space - and "wish for world peace."
The deadline for applications is Jan 17, with the final decision scheduled to be made by Maezawa at the end of March.
The matchmaking search will be filmed for a new documentary, Full Moon Lovers, which will be shown on streaming service AbemaTV.
>Windows 7 support ends
Cyber-security experts are urging Windows 7 users to upgrade their operating system.
Microsoft stopped supporting Windows 7 from Tuesday so that it can focus on "newer technologies".
As a result, Windows 7 users will no longer receive the all-important security updates and patches that keep their machines safe.
One in four Windows users is running Windows 7, according to statistics website StatCounter.
Without continued software and security updates, Windows 7 machines are more likely to be infected with viruses and malware, Microsoft wrote on its website.
Microsoft is urging people to move to Windows 10, a newer operating system that it sells for ￡120.
"Going forward, the best way for you to stay secure is on Windows 10," it said. "And the best way to experience Windows 10 is on a new PC."
微软称："今后，让电脑安全的最佳方式是安装Windows 10。体验Windows 10最好的方式是换一台新电脑。"
It is possible to install Windows 10 on old PCs but Microsoft warns that it may not run smoothly.
>China, US sign trade deal
China and the US signed the long-awaited phase-one trade deal at the White House on Thursday morning Beijing time, capping off a bruising battle that had lasted nearly two years.
The signing signaled a thaw in economic and trade relations between the world's two largest economies.
The deal, agreed to in mid-December after a dozen rounds of negotiations led by China's top trade negotiator and Vice-Premier Liu He and US Trade Representative Robert Lighthizer, was finally closed at a ceremony in the East Room of the White House that was attended by leading US officials and about 200 representatives of business, government and diplomatic circles.
It is widely expected to reduce the uncertainties that have dampened the business investment mood in both countries and around the world.
>Russian government resigns
Russian Prime Minister Dmitry Medvedev announced the resignation of his government, the Kremlin press service said Wednesday.
The decision was announced after President Vladimir Putin addressed the Federal Assembly.
Putin outlined a series of fundamental changes in his address, Medvedev said.
"In this context, it's obvious that we, as the government of the Russian Federation, should provide the president of our country with the opportunity to make all decisions necessary for this," he added.
Putin proposed the appointment of Medvedev as a deputy chairman of the Russian Security Council, while he will chair the organ.
Putin asked the government to keep fulfilling its duties until the new cabinet is formed, the Kremlin said. Later, the president named Federal Tax Service chief Mikhail Mishustin as Russia's new prime minister, according to the Kremlin.
