介绍:
We start with that new study suggesting that HIV is becoming less infectious and less deadly as it evolves. Scientists at the University of Oxford studied hundreds of women carrying the virus in Botswana. As a result, they`ve concluded that the viruses are now replicating more slowly and taking longer to cause full blown AIDS. So how significant a finding is this?
Well, it`s a good study that showed what we call the virus adapting to certain types of genetic backgrounds in individuals referred to as HLA. Each of us have different HLA profiles. The study is elegant science. I think it would be really premature at his time, to now say that the viruses are gonna be much less virulent and not really transmitting very effectively. I think the science behind the observation of the adaptation is sound. But we`ve got to be very careful that we make a real projection of what the ultimate end point of this is going to be. It’s really too early to say that, I believe.
And a weakened HIV virus would still be dangerous?
Well, certainly the HIV that’s right now circuiting in the global community is a highly dangerous virus. If you show, as the studies show, that there are adaptations to certain genetic backgrounds that could suggest that the adaptation could weaken the virus. That`s interesting observation, but the impact on the global AIDS pandemic right now, I think it`s too premature to say that that`s going to have a significant impact.
So are there implications for people already infected with the HIV virus?
No, I don`t believe so. What they are talking about is the future evolution of the virus.
The Glasgow-based film maker Duncan Campbell has won the Turner Prize, Britain`s best know award for contemporary art. The winning entry was a video reflecting on African art and images from the conflict in Northern Island. The announcement was made at the art gallery Tate Britain from where our arts correspondent Rebecca Jones sent us this report.
The winner of the 2014 Turner Prize is Duncan Campbell.

第一则消息：最新研究表明，艾滋病毒在演变得过程中，传染性和致命性不断降低。牛津大学科学家以携带艾滋病毒的数百位博茨瓦纳女性为研究对象，得出的结论是：艾滋病毒的复制速度正在降低，发展为典型艾滋病的速度正在减慢。这项发现有何重要性呢？
这项研究很好地展示了什么是病毒适应人体特定类型的遗传背景，即人类白细胞抗原（HLA）。我们每个人的HLA情况都不同。这项研究是优雅的科学。我认为现在下结论说艾滋病毒的致命性以及传染的有效性将大大降低还为时过早。我认为适应的观察背后有充分的科学理论，但是至于现在的结论是不是最终的结论，我们则需要非常谨慎。我觉得下结论还为时过早。
那么，减弱后的艾滋病毒依然危险吗？
现在国际社会中传播的艾滋病毒当然十分危险，如果你能说明，正如研究中说明的那样，遗传背景可以被适应，从而表明这种适应性可以减弱病毒，那么这是个有趣的观察报告，但至于它对全球艾滋病疫情的影响，我认为现在说它将产生重要的影响还为时过早。
那么对已经感染艾滋病毒的人群来说有什么影响吗？
我认为没有，他们说的是病毒将来的发展趋势。
日前，格拉斯哥电影制作人邓肯·坎贝尔荣获英国最著名的当代艺术奖——特纳奖，获奖作品为反映非洲艺术和北爱尔兰岛冲突画面的视频。本台文艺记者丽贝卡·琼斯从颁奖地泰特不列颠美术馆发来了报道。
获得2014年特纳奖的是邓肯·坎贝尔。
如果你想看到今年的获奖人，就得在昏暗的屋子里坐很长时间。邓肯·坎贝尔的合成视频“It for Others”已长达54分钟的时长加入比赛，对此他并无歉意。
