《国家科学评论》(National Science Review) 近日在线发表了毛河光团队建立的北京高压科学研究中心（高科中心）报道的新发现。他们利用高温高压实验，证实了地核的铁接触到下沉板块带下去的水时会发生化学反应，释放巨量的氢，留下巨量的氧。该发现一举颠覆了以往对空气中氧气来源的理解、地球深部氢气的产生、以及全球三维水循环的机制等地学的三大基本思维。

Scientists think they are closer to discovering a metallic state of hydrogen 80 years after it was first predicted to be possible. Dr. Ross Howie from HPSTAR in Shanghai explains how he and his colleges from Edinburgh University exerted the equivalent pressure found at the centre of the Earth on a tiny amount of hydrogen to create a mixed-state form of hydrogen. Outside of the lab, these exotic metals are thought to exist deep in gas giant planets – where those incredibly high pressures also exist. The Juno mission is due to arrive at Jupiter later this year, and some scientists are predicting it will reveal a metallic hydrogen centre.
