这是世界上公开展示的最大辉锑矿标本，具有数百个独立的片状晶体，令人叹为观止。辉锑矿是一种含有锑和硫的矿物。2003 年，这个近半吨重的标本从中国东南部的武陵矿中运出。由于晶体是在地下的大洞穴中形成的，因此得以成长至让人印象深刻的长度。这种长度的完整辉锑矿晶体极为罕见。更常见的情况是，采矿者会发现大块的辉锑矿矿床，但其中只有很少量独立的晶体。之后这些矿石被粉碎并“烘烤”，这是提炼锑的过程。这种金属可用于制造发动机轴承、火柴、半导体、陶瓷釉和某些药物。

们太阳系外的气态行星“热木星”的透射光谱中，首次发现重金属氧化物。 该行星 WASP-19b 和木星一样大，但是温度却高出很多，达到 2000K 左右。之前，科学家通过分析来自类似行星的光，发现了这些行星中有氢、氧、碳、钠、钾等较轻的元素，但从未发现过较重的元素。 使用欧洲南方天文台的巨型望远镜和 FORS2 光谱仪在智利圣地亚哥附近检测来自 WASP-19b 的光。天文学家使用各种模型来解释光谱，并找到了与氧化钛 (Titanium) 以及金属钠和水相对应的峰值。 他们表示，氧化钛的存在可能会改变该行星的不透明性，这可能会导致大气中出现强烈的昼夜温差。同时也可能引起大气温度的变化，通过高精度仪器探测来自该热木星和其他热木星的热辐射，在将来或许哈勃太空望远镜或詹姆斯·韦伯太空望远镜可以找到答案。 来源：《自然》 By ESO/M.

特朗普的推特已经变成了今日政治的一股“主流”。谁知道每个星期的推特马拉松会为全球关系带来什么？ 三月伊始，特朗普便宣布将对进口到美国的钢和铝分别征收25%和10%的关税。“美国优先”已然行动起来，但这一举动是否会对经济造成意想不到的后果呢？ 首先值得注意的是，这项关税措施针对的是任何出口钢和铝的国家，而非仅仅是那些在美国市场上试图“倾销”不公平补贴产品的国家。批评声音认为钢和铝产业并没有遭遇任何会影响到“保护”关税的具体威胁。澳大利亚总理发推文声明澳大利亚将被免除关税，于是剩下欧盟忐忑不安，所幸最后关头游说组织说服特朗普延缓对欧洲实行此项关税。

一份最新的报告显示，电动车在其使用寿命内所排放的温室气体比柴油发动机少得多，即使电动车是由碳强度最高的能源驱动。 比利时布鲁塞尔自由大学 (VUB) 进行的车辆全生命周期模拟研究发现，在大量使用煤炭的波兰，电动车的排放量比柴油车少 1/4。 瑞典有着欧洲最清洁的电网。其二氧化碳排放量大幅降低了 85%，是英国等国家的一半左右。 T＆E 智库发言人 Yoann Le Petit 表示：“到 2030 年，电动车的平均二氧化碳排放量将减少至柴油车的一半，当中包括制造过程的排放量。” “在过去一年中，我们接收到很多由燃料行业发布的电气化方面的假新闻，但在此项研究中，可以看到，即使在今天的波兰，驾驶电动车比柴油车对气候更有利。” 这项新研究使用了欧盟对波兰排放量的估计值 650gCO2/kWh，这远低于去年欧盟委员会联合研究中心科学部门的计算结果。

研究人员发现，液态金属滴可以变成雪花状。 当美国北卡罗莱纳州立大学的一个科学家小组试图用液态镓铟作为电化学电池中的电极时，他们发现了奇怪的现象：在几秒钟内，金属开始扩散成雪花状。液态镓铟具有液体中最大表面张力，其形态很少发生改变，因此这是极不寻常的现象。 但施加中等电压会引起镓合金与周围电解质（氢氧化钠水溶液）之间的反应。金属表面出现氧化并降低了表面张力，就如肥皂会降低水的表面张力一样。当重力将金属扩散成圆盘状，表面的干扰会将其分解成一片片的“雪花”。“雪花”继续变化，分裂出更多的碎片，形成图案。 参考文献 C B Eaker 等，《物理评论快报》2017, 119, 174502 (DOI:10.1103/PhysRevLett.119.174502)
