Passage One
文章一
Researchers have identified a potent new antibiotic compound using artificial intelligence.
研究人员利用人工智能发现了一种新型强效抗生素化合物。
The antibiotic can kill very dangerous bacteria.
这种抗生素可以杀死非常危险的细菌。
According to a study published in the journal Cell, the compound successfully removed deadly strains of bacteria in mice which are resistant to all known antibiotics.
根据发表在《细胞》杂志上的一项研究，该化合物成功地清除了老鼠体内对所有已知抗生素都有抗药性的致命细菌菌株。
The researchers say this is the first time that artificial intelligence has been used to find a powerful new antibiotic molecule.
研究人员表示，这是人工智能首次被用于寻找新型强效抗生素分子。
Why does this matter?
为什么这很重要？
The answer is antibiotic resistance.
答案是抗生素耐药性。
This happens when bacteria develop the ability to survive the medications designed to kill them.
当细菌能够在旨在杀死它们的药物中存活下来时，就会发生这种情况。
Antibiotic resistance is a serious threat to health and the problem is growing.
抗生素耐药性会对健康构成严重威胁，而且这个问题正在加剧。
This makes finding new antibiotics very important.
这使得寻找新型抗生素变得非常重要。
However, in recent decades very few have been developed and those that have tend to be very similar to drugs already available.
然而，近几十年来，很少有新型抗生素被开发出来，而且这些抗生素往往与现有的抗生素非常相似。
The searches also tend to only focus on a narrow spectrum of chemical compounds, but this is where artificial intelligence comes in. Why?
（科学家）往往只搜找一小部分化合物，但这就是人工智能的用武之地。为什么？
To find new drugs, scientists screen molecules to predict how effective they might be.
为了寻找新药，科学家会对分子进行筛选，以预测它们的效果。
Typically, such screening is done by humans in the lab, which is both costly and slow.
通常情况下，这种筛选过程是由人类在实验室里完成的，这既昂贵又缓慢。
Artificial intelligence is different.
人工智能则不同。
It’s fast, and it can process a high volume.
它速度快，处理量大。
It can screen hundreds of millions of compounds to identify a few interesting candidates that require experimental testing.
它可以筛选数亿种化合物，找出一些需要进行实验测试的有趣的候选化合物。
Artificial intelligence is also able to predict if compounds are likely to be toxic.
人工智能还能预测化合物是否可能有毒。
Some experts assert that this work signifies a paradigm shift in antibiotic discovery.
一些专家断言，这项工作标志着抗生素发现发生了范式转变。
It could change drug discovery more generally.
它可能会改变更普遍的药物发现。
