为什么人类要演化出忍受牛奶的能力
乳制品有了竞争对手,由大豆、杏仁等植物制成的替代“牛奶”越来越受欢迎。这些替代品通常适合素食主义者,以及对牛奶过敏或者乳糖不耐受的人。2018年,英国版《学徒》(The Apprentice)节目的亚军,就经营着调味坚果奶生意。 但替代奶的兴起,只是人类与动物奶关系的一个最新发展。这种关系可以追溯到几千年前,历经起伏。 想想看,奶水真是一种奇怪的饮品。它是牛或者其他动物喂养幼崽的液体食物,为了获得牛奶,我们还得把它从母牛的乳房里给挤出来。 在许多文化中,这几乎是闻所未闻的事情。2000年时,全中国范围内…

爱因斯坦预言百年 引力波终被发现
距离爱因斯坦1916年预言引力波存在一百年后,科学家们终于证明了这一预言。 引力波是科学界公认最难探测的尖端科技之一。一些评论人士认为,这可能是二十一世纪最伟大的发现之一。 周四(2月11日),美国激光干涉引力波天文台(LIGO)执行主任大卫•瑞兹在华盛顿宣布,科学家们多年寻找引力波的努力终于有了成果。 在爱因斯坦1916年提出的广义相对论中,引力波被认为是由质量所引发的时空扭曲而成,任何有质量的物体在加速运动时都会对周围的时空产生影响。而这一作用形式就是所谓的引力波。 科学家们此次检测到的引力波,是在…
