当然,这只是一个简单的描述。新闻原文如下:
Physicist convicted over links with Iran and China
On 3 September, a federal jury found electrical engineer J. Reece Roth, 70, guilty on 17 counts for conspiracy, wire fraud and violating the Arms Export Control Act. Roth, a professor emeritus at the University of Tennessee in Knoxville, had been working on ways of using plasma to reduce drag on aircraft wings.
He had employed both Chinese and Iranian graduate students without proper authorization (see Nature 442, 232; 2006). Roth will be sentenced on 7 January 2009; he faces a maximum sentence of 150 years.
The conviction serves as a warning to other academics, says Russ Dedrick, a US attorney with the Eastern District of Tennessee. "Our scientific and educational communities must take precautions to ensure that technology and research are protected," he says.
“我们要用革命的恐怖,来战胜反革命的恐怖”
他们学得可真到家。

让我们继续,某些科学家最近发现病毒也会生病——巨大的"Mamavirus"病毒会被"Spuntik"病毒侵袭。这让有关生命的定义的争论又有了新材料,不过,名词之争真的有很大意义吗?

另外一些科学家则通过新找到的尼安德特婴儿遗骨,推论出这些人类最近的近亲实际上在出生时有和人类一样大的大脑(也就意味着一样大的脑袋),并且在出生后也有一个迅速的大脑发育期(我们知道,事实上这些尼安德特人的大脑是比现代人要更大的)。由此科学家提出一个问题,是否这几万年来的人类大小缩小趋势是人类竞争胜过尼安德特人的关键(因为能量节省)?如果属实,这也许说明了必要的野蛮还是需要的——即使要付出智力的代价。
