欧洲发现大型稀土矿；香港中文大学研制出《终结者》机器人

1) Europe’s big rare earth discovery seen as ‘game changer’ in bid to address China’s dominance.

欧洲在稀土上有重大发现。

欧洲发现了一个大型稀土矿床，被认为是潜在的游戏规则的改变者。这一发现可能会增加竞争并减少对外依赖。该矿床位于挪威，被认为是世界上最大的矿床之一。预计将于2025年开采。

The discovery is estimated at more than 1 million tonnes.

From the 1960s to the 1980s, the US was the global leader in rare earth mining and production. That is no longer the case.

2) Watch a Real-Life 'Terminator' Robot Turn Into Liquid to Escape a Cage.

科员人员研制出现实生活中的《终结者》机器人，它可以变成液体逃离笼子。

由香港中文大学进行的该项研究并不是受《终结者》的启发，而是受海参启发。海参的身体可以自由地变软或变硬。研制出的小机器人使用了电磁颗粒和镓。

随着深入的研究和技术成熟，科员人员希望有一天这种技术能够用于生物医疗方面。

In tests, the mini robots were able to jump over obstacles, scale walls, split in half and re-merge all while being magnetically controlled.

Future work should further explore how these robots could be used within a biomedical context.

3) Apple Will Put Its Reputation on the Line With New Mixed-Reality Headset.

苹果将推出混合现实头戴式耳机，苹果也许是拿这个产品赌它的声誉。

苹果将于2023年发布一款混合现实头戴式耳机。该耳机将提供身临其境的高质量虚拟现实体验，预计该产品对科技行业将产生重大影响。

一些人认为，这款耳机最终可能会取代iPhone，成为日常使用的主要设备。但另一些人表示怀疑，因为它的售价大概是3千美元，充电后能只用2小时。

It will undoubtedly be a marvel and far more advanced than anything else on the market.

But it will also be impractical and too expensive for most consumers. That’s because it will only last about two hours per charge, not work well outdoors, launch with a limited array of content and feature a design that some have deemed uncomfortable.
