科学家表示，响尾蛇已经进化出一种聪明的方法，让人类误以为危险比他们想象的更近。 The sibilant sound of the rattlesnake’s tail has long been a cinematic cliche. 响尾蛇尾巴发出的嘶嘶声早已是大银幕上的常用套路。 That tell-tale rattle is made by the rapid shaking together of hard rings of keratin…
医生表示，阿司匹林或许能够有助对抗侵袭性乳腺癌，让那些很难治疗的肿瘤对某些抗癌药物产生更积极的反应。 Around one in five breast cancers are triple-negative. It’s a type that hormone treatment and most targeted cancer drugs don’t work against. 大约五分之一的乳癌病例属于三阴性乳腺癌。激素治疗和大部分针对性抗癌药物对这种乳腺癌都没有作用。 8,000 women are diagnosed with this…
天文学家捕捉到了迄今为止最详细清晰的一些深空星系图像，其清晰度要远高于普通图像，这些超清图像以前所未有的细节揭示了星系内部的运作情况。 The images have been created from the radio waves emitted from the galaxies. 这些图像是根据从星系发出的无线电波生成的。 What’s new is that the team has dramatically improved the resolution of the radio images…
科学家正在测试一种人工智能系统，据信，仅需进行一次脑部扫描，即可诊断出失智症。该系统还有可能可以预测患者病情是会持续多年保持稳定、缓慢恶化，还是需要立即接受治疗。 Currently, it can take several scans and numerous tests over months or even years to diagnose dementia, but this new artificial-intelligence system might be able to identify dementia after…
根据对90项研究进行的分析，那些预先混合好然后卖给农民的农药会杀死两倍数量的蜜蜂。 Our bees face multiple threats to their survival – from a loss of food rich natural grassland to the dozens of chemical pesticides that are commonly used in agriculture.…
一项研究发现，大约三分之一的英国中年人有多种健康问题，如慢性背痛、心理健康状况不佳和高血压。 The findings come from nearly 8,000 adults taking part in the 1970 British cohort study that spans more than 50 years of life. 这些调查结果来自对近8000名成年人的研究，他们参与了1970年英国的一项定群研究，幅度跨越了他们人生的50余年。 Around one-in-three of this group…
当提到章鱼和龙虾时，你的脑海里会想到什么？是海鲜食品还是智慧海洋生物？ Some creatures are so different from us that we can only guess how aware or sentient they are. An octopus has arms that can smell and taste. They can…
在出行后统计你车上被撞扁的虫子数量，也许能帮助科学家了解英国昆虫物种的数量。昆虫保护慈善机构 “Buglife” 推出了一款名为 “Bugs Matter” 的新应用程序，希望人们能用它来收集信息，帮助科学家了解特定物种在哪里繁衍生息或逐渐减少。 ‘Insectagedden’ is how the global decline in insect populations has been described by some scientists. One case study in Germany suggested there’d been a…
鸟类如何长途跋涉，飞越海洋和陆地？科学家离揭开这个谜团又近了一步。 Scientists studied the robin – a familiar garden bird that can sometimes migrate – flying alone, at night and often over great distances. They identified a magnetically sensitive molecule…
英国贝尔法斯特女王大学带领的一支国际研究团队认为，由于金星的云层实在太干燥，生命不可能存在于那里。 It’s an audacious idea: the notion that microorganisms could be floating through the atmosphere of Venus. It would be extremely challenging, of course, because we know the planet’s clouds…
一项深入研究亚马逊雨林历史的研究发现，原住民在此居住了数千年，却 “没有造成明显的物种损失或干扰”。 This was an exercise in botanical archaeology, with the researchers examining layers of rainforest soil excavated in a remote corner of northeastern Peru. They dated each layer and…
生物学家发现了世界上最小的潜水哺乳动物 —— 水鼩的基因秘密。 Water shrews are diminutive, long-snouted mammals. They weigh less than one AA battery, and lose heat quickly, and burn energy constantly in tiny active muscles. 水鼩是一种体型纤小、长吻的哺乳动物。这类动物的体重还不足一节 AA（5号）电池，它们体内的热量会迅速流失，微小的活动肌肉中不断燃烧着能量。…
科学家们报告说，这是迄今为止观测到的持续时间最长的沉积物崩塌。崩塌发生在非洲西侧刚果河河口切入海底的一条深邃峡谷中。 We’ve all seen pictures of an avalanche falling down a mountain. Now, imagine this mighty force tumbling down a slope for two whole days. This gives you a sense…
英国宠物零售商 “Pets at Home” 的全年零售额首次突破10亿英镑，这是由于宠物主人更舍得花钱把他们的宠物当作 “小主人” 般伺候，包括给狗狗购买用来玩乐的游泳池。 The dilemma of what to do with your dog while you’re at work has long been a major barrier for many who’d like…
通过利用藻类中首次发现的感光蛋白，一名完全失明男子的部分视力得到了恢复。 The man from Brittany in France was diagnosed with retinitis pigmentosa 40 years ago. Doctors used a pioneering technique called optogenetics to try to restore his vision. 40年前，这名来自法国布列塔尼的男子被诊断患有视网膜色素变性。医生们用了一种名为光遗传学的开创性技术来试图恢复他的视力。 It’s…
