Here in Manchester, graphene has been used to create a filter. The aim is to convert sea water into a form that’s drinkable. Drinking water will be scarce for 1.2 billion people by 2025.

在英國城市曼徹斯特，人們已開始利用石墨烯來制造一種濾水紙。這樣做的目的是把海水轉化成可供人飲用的狀態。到 2025年，全球將有12億人缺少飲用水。

The rapid success of China’s bike hire companies took everyone by surprise. As you can see, there are spaces in Beijing which are now totally crammed with bikes. The beauty of these is you scan them with your phone and then leave them wherever you like for the next person. Some of those complaining about the bikes want to park cars on the footpath.

在中國，自行車租賃公司的迅速成功讓所有人大吃一驚。你可以看到，北京的一些街道上完全停滿瞭自行車。這些供租賃的自行車的妙處在於，隻要用手機掃一掃，人們就可以騎走自行車，使用完後則可把車放在任何一個地方，以供下個人使用。一些抱怨自行車占據瞭城市的空間人其實是想把機動車也停在人行道上。
