English Bulldog in need of 'new blood' 英国斗牛犬需通过杂交改善健康
科学家认为将英国斗牛犬与其它犬种杂交可能是保证其生存的最佳途径。数百年来,为保留其特定的外貌特征,斗牛犬一直沿袭同系间交配。然而一项基因研究表明,如果没有“新鲜血液”的帮助,该品种将面临一系列健康问题。请听报道。
The English Bulldog was one of the most popular breeds across Britain and America last year. But during the latter part of the last century, many bulldogs were bred to have exaggerated physical features, which led to health issues including breathing difficulties.
Researchers at the University of California say popularity can no longer excuse the health problems that the average bulldog endures. And they say the gene pool has become so small, it could be difficult to improve the health of the English Bulldog without cross-breeding.
The Head of Health and Research at the Kennel Club, Aimée Llewellyn-Zaidi, said they continue to look at ways to ensure the sustainability of a breed if it is at risk, and they're working with breed clubs and researchers in order to do this.

umans make rainforest more flammable 人类活动使热带雨林更易燃
研究人员说,人类活动使亚马逊雨林变得更易燃。这是由一项关于巴西亚马逊地区的研究所得出的结论之一,该结论表明即使是被保护的丛林也会受到影响。这项调查的成果已在《自然》期刊上发布。请听 Victoria Gill 的报道。
(sound) The sound of burning rainforest. This is from footage captured by researchers in the Eastern Amazon. Their two-year study found that evenselective logging in protected forests opened up the canopy enough to dry out the undergrowth and make it catch fire more easily.
To measure the impact of human activity on the rainforest, the team counted 2,000 species of trees, insects and birds, comparing biodiversity with the amount of forest cover, and you can hear the difference.
While a pristine undisturbed rainforest sounds like this (sound), far fewer species contribute to the chorus when the forest is degraded (sound).
This large-scale study showed that areas with 80% forest cover lost up to half their biodiversity.

Hands-free phone use by drivers 'distracting' 研究称使用免提电话同样会使驾驶员分心
研究人员发现,在开车时使用手机免提功能通话和拿着手机通话对驾驶员注意力的干扰不相上下。主要研究人员称,此研究结果为禁止在开车时使用任何方式接听电话提供了充分的证据。以下是 Richard Westcott 的报道。
You might think that going hands-free in the car is much safer than holding the phone in your hand. This research suggests that, although it's easier to physically control the car using both hands, the conversation itself could be dangerously distracting for your brain.
Psychologists at the University of Sussex say that when drivers are forced to visually imagine what they are talking about on the phone, they're using a part of the brain they'd normally use to watch the road. So asking a simple question like "where did you leave the blue file?" can mean a driverconcentrates on an area four times smaller than normal, because their brain is imagining the room where they've left the file instead of checking forhazards.
Drivers who took part in the research also took just under a second longer to react to a pedestrian stepping off the pavement and to an oncoming car on the wrong side of the road.
Having a passenger next to you is less distracting, the researchers argue, because you both stop talking when the driver needs to concentrate.

Doctors support switch to e-cigarettes 英国医生支持吸烟者使用电子烟
一家领先的医学机构说,吸烟者应被鼓励使用电子香烟来帮助他们最终戒烟。英国皇家内科医学院解释说,吸电子香烟比吸传统烟草要安全很多。以下是 Adam Brimelow 的报道。
The growing popularity of e-cigarettes has prompted debate about their safety, their potential to help people quit tobacco smoking and the risk they may encourage some people to take it up .
The Royal College of Physicians concludes that their impact so far has been very positive. They've helped many thousands of people to quit and the switch from tobacco smoking is a dramatic step towards better health.
It says any possible harm from long-term use is likely to be very small and it concludes fears that e-cigarettes are a gateway to smoking areunfounded .
The report has been widely welcomed though the Faculty of Public Health has sounded a note of caution . It said that more research was needed to understand the risks.

Big increase in diabetes 糖尿病患者人数剧增
根据世界卫生组织的报告,大约每十一个成人中就有一个人患糖尿病。统计数字显示,全世界每年有150万人因患糖尿病而死亡。以下是 BBC Krista Beighton 的报道:
The World Health Organisation says we are facing an unrelenting march of diabetes cases. In a major report it warns that cases rose from 108 million in 1980 to 422 million in 2014.
The increase is predominantly down to type 2 diabetes - the form associated with poor eating habits.
In the 1980s the highest rates were found in affluent countries. But in a remarkable transformation it's now low and middle income countries seeing the steepest increase in cases.
The WHO says the numbers will continue to rise unless drastic action is taken.
