Acupuncture cuts period pain
研究:针灸能够缓解痛经

Acupuncture can significantly reduce the severity and duration of period pain, a study has found. The study conducted by Australian and New Zealand researchers also found it relieved associated headaches and nausea. It was a small pilot study of 74 women aged between 18 and 45 which found that more than half had at least a 50% reduction in the severity of their period pain after undergoing acupuncture treatment. 
一项研究发现，针灸可以极大地减少痛经的严重程度和持续时间。这项由澳大利亚和新西兰研究人员开展的研究还发现，针灸能缓解与痛经相关的头痛和恶心问题。这是一个针对74位年龄在18到45岁之间的女性的小型初步研究，结果发现接受针灸治疗后，超过一半的人痛经的程度至少减轻了一半。

The women underwent the treatment for three months, with the effects lasting for up to a year. Many of the women also reported less of a need to use painkillers to treat their period pain and an improvement in secondary symptoms including headaches and nausea. Many also experienced improvements in PMS-related symptoms such as mood swings. 

她们接受了为期3个月的针灸治疗，疗效持续了长达1年。许多女性还表示，她们没那么需要用止痛药来治疗痛经了，并且头痛和恶心等次要症状也得到改善。很多人还称，情绪波动等经前综合征相关症状也有所改善。

More women freeze eggs

更多女性选择冷冻卵子

In western countries, soaring numbers of women are freezing their eggs as an "insurance policy" to beat their biological clock. Career women have long been thought to be putting motherhood on ice because they choose their job over a baby. However, most women who freeze their eggs are doing so not because of their career but because they cannot find a similarly successful man. 

在西方国家，将卵子冷冻起来作为"保险对策"对抗生理时钟的女性数量大幅增长。长期以来，人们认为职业女性推迟当妈妈是因为她们选择的是事业而非孩子。但大多数女性并非为事业才选择冷冻卵子，而是因为她们找不到和自己同样成功的男性。

Marcia Inhorn, professor of anthropology at Yale University, said of women who freeze their eggs: "There are not enough graduates for them. In simple terms, this is about an oversupply of educated women." The gender gap for higher education is now as large as that between rich and poor people. Describing the phenomenon, Professor Inhorn said: "Maybe women need to be prepared to be more open to the idea of a relationship with someone not as educated."

耶鲁大学人类学教授马西亚•英霍恩表示，冷冻卵子的女性"可选择的高材生不够多。简而言之，就是知识女性供过于求。"如今高等教育的性别差距和贫富差距一样大。针对这一现象，英霍恩教授称："也许女性需要做好准备，以更加开放的态度对待和教育程度不如自己的人谈恋爱这件事。"

Smartphone makes you dumb

研究:智能手机让人变笨

Now there is evidence for the common belief that the smartphones in our pockets are actually making us dumber. The constant presence of a mobile phone has a "brain drain" effect that significantly reduces people's intelligence and attention spans, said researchers at the University of Texas. 

人们普遍认为，我们口袋里的智能手机其实在使我们变笨，现在有证据证明这一观点了。德克萨斯大学的研究人员称，手机的长期在场会产生一种"脑力流失"效应，使人们的智力和专注时长严重降低。

They discovered that people are worse at conducting tasks and remembering information if they have a smartphone within eye shot, even when the phone is set up not to disturb or switched off. Meanwhile, the negative effect was worse for those who were deemed more dependent on their mobiles. The researchers said the effect arises because part of a smartphone users' mind is dedicated to trying to not think about distractions, such as whether they have any messages, when the handset is in their line of sight.

他们发现，当手机在视线范围内时，即便将其设置成防干扰模式或关机，人们在处理任务和记忆信息方面的表现也会更糟。同时，越依赖手机的人受到的负面影响越严重。研究人员称，"脑力流失"效应之所以产生，是因为当智能手机在视线范围内时，使用者的部分注意力被用来努力阻止自己去想"有没有收到短信"之类令人分心的事。
