Сколько стоит предательство, если ты знаешь цену выкупа?

地球上的大部分水资源都是海水，由于盐分过高而无法饮用。海水淡化厂可将海水淡化处理成饮用水，然而该过程需要消耗大量能源。香港研究团队在《ACS Energy Letters》发表研究成果，其研发出一种具有长链微气囊结构的海绵结构材料，结合阳光照射与简易塑料罩，成功实现盐水资源向淡水的转化。一项户外原理验证实验成功在自然光照条件下产出可直接饮用的淡水，标志着实现低能耗可持续海水淡化技术的重大进展。在户外测试中，研究人员将这种材料置于盛有海水的蒸发容器中，上方覆盖弧形透明塑料罩。阳光加热海绵结构材料顶部时，仅会将水分蒸发为水蒸气（盐分会被阻隔）。蒸气在塑料罩内壁凝结为液态水，沿罩壁汇集至边缘，最终滴入蒸发容器下方的漏斗中，以另一容器盛放。经过 6 小时自然光照，该系统最终产出约 3 汤匙的饮用水。

天文学家最近发现一颗名为 HIP 67522b 的系外行星，跟它的母恒星 HIP 67522 的互动关系非常不寻常。这颗行星靠母星非常近，导致恒星表面频繁发生激烈的耀斑，也让行星的大气层持续受热膨胀。HIP 67522 是一颗年轻的 G 型恒星，位于半人马座，距离地球约 417 光年，年龄大约只有 1,700 万年。这颗恒星拥有两颗行星，其中 HIP 67522b 是一颗「热木星」——体积接近木星，由于公转轨道非常靠近母星，绕转一圈只需 7 天的时间。研究团队发现，这颗行星似乎能与母恒星的磁场产生某种奇特的连结，进而引发恒星表面出现剧烈的耀斑活动。这些耀斑朝向行星爆发时，又把大量能量「反馈」到行星身上，使它的大气层像吹气球一样不断膨胀。长期下来，行星的大气可能会被严重剥离，甚至从一颗巨大的热木星，缩小成像「热海王星」或「亚海王星」那样的体积。这类母星与行星之间的强烈互动，早就在理论上被预测过，但直到现在才首次被实际观测到。
