6. Nets Drive
Evolution of Small Fish
In a test lake stocked with two types of trout, fishing with nets mostly caught larger, faster-growing fish, leaving smaller, slower growers to survive and pass on those traits. Karen Hopkin reports.



Being a big fish in a small pond is more likely to get you noticed. That’s good news if you’re, say, the best pitcher in your little league division. But it’s not so good if you’re an actual fish. Because bigger fish are the ones that tend to get caught. Not only is that bad news for the fish, but it may be bad for the whole fish population. Or so say scientists from Australia and Canada
in the online edition of the Proceedings of the National Academy of Sciences. They find that fishing for the largest individuals targets the fastest growers, leaving behind their slower-growing counterparts. Which means that current fishing practices may favor the evolution of slower-growing fish.


The scientists stocked two small lakes in British Columbia with two strains of rainbow trout: one that grows quickly and is more aggressive in chasing down food and another that grows slowly and tends to be more cautious. They then used commercial gillnets to fish the lakes and found that they bagged the bolder fish three times faster than the shy ones, which were left behind to multiply. So we could inadvertently be breeding fearful small fry that are nearly impossible to catch. Which would make them…hard-to-see food.

7.Better Beams Give More Big Bang For Buck
Particle beams traveling at almost the speed of light get lined up after information going even faster tells devices to straighten things out. The result may provide information about the Big Bang. Cynthia Graber reports.
-------------
Physicists at the Brookhaven National Laboratory have been able to send information ahead of particle beams racing at nearly the speed of light. And the message to the beams is: Get in line. This technique has been developed at other labs but never used before with particle beams traveling in discrete bunches. These bunches are important in recreating that singular moment, the Big Bang.
In these experiments, there are two different sets of ions, electrically charged particles, zooming towards each other around a 2.4 mile track. They collide into one another to recreate conditions that provide info about the Big Bang. But the ions spread out as they move. And this means that there are fewer collisions.
In a technique called stochastic cooling, scientists first measure fluctuations in the beams of ions. Then they send signals even faster than these particles to devices up ahead that can kick these particles back into shape. Researchers say this technique allows them to create these collisions much more frequently and cheaply than other methods. And so they can get more and better data about what our universe might have been like just after it came into existence.

这一篇有点专业哦，有些不懂！~

刚刚跟着楼主的脚印听了第一篇.觉得最难的一句是:It’s a hand-held of unit, about the size of a key chain, it automatically identifies the form of transportation the carrier is taking

key chain,我听成了kitchen呵呵.语速我暂时可以接受,但因为对内容不熟,一句没听懂就可能影响对全文的理解.

60秒比较短,觉得听起来比较轻松,打算跟着楼主一天听一篇.

google了一下,carbon footprint原来是这个意思: A carbon footprint is a measure of the impact our activities have on the environment, and in particular climate change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for electricity, heating and transportation etc.

The carbon footprint is a measurement of all greenhouse gases we individually produce and has units of tonnes (or kg) of carbon dioxide equivalent.

8. This Is Your Brain On Arts

A three-year, multi-institutional study finds that early training in performing arts is really good for the brain. Steve Mirsky reports. For more info, go to www.dana.org

Are smarter people drawn to music, theater and dance? Or does arts training in childhood change the brain in positive ways?In 2004, the philanthropic Dana Foundation created a consortium of neuroscientists from seven universities to address those questions.On March 4, the group released a report, Learning, Arts, and the Brain, available at dana.org. Some of the findings:An interest in performing arts helps develop sustained attention spans, which can improve other areas of cognition. Links exist between training in music and the ability to manipulate information in both short-term and long-term memory.Music training also appears to improve kids’ capacity for geometric representation, as well as the acquisition of reading skills.Acting classes lead to improved memory, via better language skills.Dance learning is done through observation and mimicry, and that training appears to improve other cognitive skills.So science says that dance, theater and music can make life full of sound and glory, signifying something.

你GOOGLE的很受用呀，还是看英文解释更地道！~
恩恩，有你们一起努力，偶必须坚持啊！~~先补上昨天的！~
