一家为盲人和弱视者设立的慈善机构英国导盲犬(Guide Dogs UK)制作了一套伴书气味盒,以配合畅销儿童故事书《咕噜牛(The Gruffalo)》。该机构创造了一套鼻腔吸入器,分别代表主人公咕噜牛和它遇到的四个角色:蛇、狐狸、猫头鹰和小老鼠。 The Gruffalo was first published in 1999, but the charity Guide Dogs UK say they've created…
英国的科学家们表示,一项简单的皮肤拭子检查可用来帮助诊断退化性大脑疾病帕金森病。对志愿者的研究表明,该检查能快速测出皮脂中显示患病迹象的化合物,皮脂是一种保护皮肤的油性物质。 There are an estimated 145,000 people living with Parkinson's in the UK, but there is no cure and no definitive test for the…
有长效危害的被禁工业化学品可能威胁到在英国附近生活的雄性鼠海豚的生殖能力。多氯联苯在几十年前就被逐渐淘汰了,但这种物质会在鲸鱼、海豚和鼠海豚的体内积聚。 PCBs were once used in everything from plastics to paints. They were banned in the 1980s, but the chemicals take a long…
意大利考古学家在古罗马城市庞贝附近发掘出了一架礼仪马车。这架四轮马车是在一个马厩附近发现的,早在2018年,人们就曾在这个马厩里发掘出三匹马的遗骸。 Ancient Romans liked a celebration. And much like royals in the modern United Kingdom augment grand events with processional carriages, well-to-do citizens of first century Pompeii were…
一项新的研究表明,鲸鱼被渔网缠住的风险似乎被低估了。无人机拍摄的照片上显示,在加拿大圣劳伦斯湾,多达60%的蓝鲸与渔绳和渔网接触过,因为从照片中能看到它们身上的疤痕。 Getting caught up in fishing ropes or nets is one of the biggest threats to whales. The animals can suffocate or starve after becoming trapped. Reports…
科学家们首次利用卫星图像统计非洲大象的数量。照片由一颗在地表600公里(372英里)外轨道上运行的地球观测卫星拍摄。这一突破可以让人们在无云日里对5000平方公里的大象栖息地进行观测。 When you first look at it, the image is a series of grey blobs amid a forest of green splotches. But when…
一项对鸣鸟解决问题能力的测试揭示了交通噪音是如何损害这些动物的能力的。科学家们给珍珠鸟设计了一组 “觅食任务”,分别在有噪音和无噪音的环境下进行。 Rather than studying birds in the wild, these researchers brought recordings of traffic noise from the nearby road into their…
科学家们表示,鲨鱼和鳐鱼正以 “惊人” 的速度从世界海洋中消失。一项新研究表明,半个多世纪以来,公海海域的鲨鱼数量减少了71%,导致这个现象的主要原因是过度捕捞。在所有被研究的物种中,有四分之三正面临灭绝的威胁。 The study found a dramatic decline in sharks and rays found in the open oceans, including hammerheads, mako sharks,…
研究人员一直无法理解小巧的蝴蝶是如何用它们巨大但低效的翅膀飞行的。现在,一项新的研究表明,蝴蝶进化出了一种有效的合拢和拍打翅膀的方式来产生推力。 The fluttering flight patterns of butterflies have long inspired poets, but baffled scientists. The delicate creatures have unusually large wings, which are aerodynamically inefficient. But…
很长一段时间以来,科学家们一直试图弄明白斑马的身上为什么有条纹,以及这种独特的黑白图案到底是如何帮助它们抵御潜在的掠食者的袭击。早期的博物学家就此提出了 “运动眩晕” 理论,但科学家们发现,动物运动时的保护机制可能另有原因。 It's something that's puzzled biologists for over a century. You might think if you're trying to avoid being hunted down and…
