Transgenic Canola Plants Break Free

one of the concerns about working with genetically modified <转基因的>crops has been that vegetation growing in agriculture fields might escape out into the world. Now for the first time in the US, researchers report a large population of gm crops beyond the farm. Transgenic canola plants in north Dakota have<原文为had 但是我怎么听都是have> recieved genes making them resistent to herbicides<这个词的读音是er...不是her..>, such as the weed killer Roundup<草甘膦 是一种温和对环境破坏性较低的除草剂>. Researchers collected and tested 4 hundred ans 6 canola plants along thousands of miles of state roads. They found 347 carrying a least one resistence gene, there were also indications that the inserted<光听的时候听出来了 一听写就听不出来 好几次 不知道为啥> genes were being passed onto new generations, producing some plants in the wild with multiple transgenes. The findings represanted on August 6th at the annual meeting of the ecological society in the America in Pittsburg. The transgenic canola plants are not about take over<怎么听都听不出来over 都是off>the world, but researchers are obviously curious about how these particular plants managed to make it in places like the edges of parking lots rather than pampered fields. And the answers they found will likely to affect future biotechnology regulation.

你们都怎么个听抄法啊？我不管是手写还是key-in都跟不上播音员念句子的速度额。。难道要听一句暂停一下吗？那不就破坏了连贯的感觉？

试着听了一个，发现自己词汇量还是太少了，很多词都不知道是什么，下面黄色的词就是自己没听懂瞎写的。。
Anyone familiar with psychology has probably heard a statement like this. a significant percentage of male and female undergraduates displayed x when prompted by y and typically the conclusion of the study is something alike, so humans display x in the presence of y. well taking the behaviour of undergrads’ extanding towards the humanity is the intreacking leap right? well to be fair for research purposes undergrads are cheap and excessible but as noted by the blocker height case such terms are better used to describe a hot date rather than good data. well a group from the University Colombia recently publish a normous manalcese of the danger of assuming that all the humanity closely matches the behavior of 20 something college students. they set evidence that between 2003 and 2007 undergrads made up 80% of study subjects in 6 top psychology journals.

正确的原文如下：
Anyone familiar with psychology has probably heard a statement like this: A significant percentage of male & female undergraduates displayed X when prompted by Y.  And typically the conclusion of the study is something like: So humans display X in the presence of Y. Taking the behavior of undergrads and extending it to all of humanity is an intriguing leap, right?
To be fair, for research purposes, undergrads are cheap and accessible. But, as noted by the blogger Headcase, such terms are better used to describe a hot date rather than good data.
Well, a group from the University of British Columbia recently published an enormous meta-analysis on the danger of assuming that all of humanity closely matches the behaviors of 20-something college students. They cite evidence that between 2003 and 2007 undergrads made up 80 percent of study subjects in six top psychology journals, and that 96 percent of all psychology samples come from countries that make up only 12 percent of the world’s population. They call this the WEIRD population—Western Educated Industrialized Rich Democratic—and say that they are the least representative populations one could find for generalizing about humans.
The researchers found huge variability between global populations along measures of motivation, self-perception, reasoning, heritability of IQ and even visual perception. For instance the Muller-Lyer visual illusion, which shows two lines of equal length where one is often perceived at least by American undergrads, as longer than the other, is actually not an illusion at all for the San foragers of the Kalahari. The authors also note points of similarity like this one: in 37 populations males tend to rank physical attractiveness of mates to be more important than do females.
The main plea from the researchers is that far too often these so-called WEIRD populations are actually the "outliers" and psychologists need to be less cavalier about labeling some behavior as human nature based on the desires, emotions and culture of a group of 19-year old co-eds.

汗啊错好多。。另外不是很懂里面的Population作何解释。。比如in 37 populations这是什么概念？

8/9： Blue Whales Synchronize Song Pitch

Blue whales off the California coast make calls that, sped up 10 times, sound like (sound of two-part call). The original is a wall-rattling frequency too low for us to hear. Scientists analyzed around 2,500 of those calls, and found that the second part (sound) is nearly identical in pitch every time from each whale: 16 hertz, or four octaves below middle C. And the slight variations in frequency that do exist are only a tenth of the difference between a C and a C sharp. Those findings appear online in the Journal of the Acoustical Society of America.

The researchers don't know how many different individual whales they caught singing, or why even they sing at all. But past studies suggest only blue whale males make calls like this. So the investigators speculate that males might synchronize to a single common pitch as a sort of mating beacon.

Thanks to the Doppler effect, females swimming towards a male would hear a slightly higher pitch; swimming away, a lower-pitched moan. Serenade out of tune—you might be swimming solo tonight.

正确原文：
The ancient inhabitants of Amazonia knew how to keep fragile soils fertile—and may have hit upon a way to combat present-day climate change. That technique? Biochar, or any plant or animal waste turned to charcoal and put back into the ground.

Studies suggest as much as 900 million metric tons of carbon a year could be locked up this way—and improve the soil's ability to grow crops as well. That's nearly 20 percent of current CO2 emissions as a result of burning fossil fuels.

And a new study shows that biochar could have an impact on agriculture's other greenhouse gas emission: nitrous oxide, or laughing gas, which is no laughing matter when it comes to climate change. Biochar applied to Australian fields and left for a number of months cut such emissions by more than 70 percent, as well as preventing nitrogen and ammonia from leaching out of the soil in water. Such fertilizer leaching is responsible for dead zones across the world, like the one at the mouth of the Mississippi River currently.

Of course, biochar is no panacea, despite fans like Richard Branson. Some studies suggest biochar can accelerate microbes degrading organic matter into dread CO2 in places like the boreal forests of the northern hemisphere. But perhaps charcoal is better in soil than burned as fuel for barbecues. The terra preta soils of Brazil are still being farmed, centuries after the biochar was added.

8/10: Case Study: Tongue Stud Play Causes Front Teeth Gap

That’s what it might sound like if I had a tongue stud, hitting my teeth. Maybe you’ve seen people with studs in their tongue clicking it up against their front teeth, a move known as “playing.” But it turns out that the habit may destroy some smiles.

University of Buffalo researchers noticed that local high school students who had a barbell-type tongue stud commonly pushed the piercings against their front teeth. Then they examined a 26-year-old patient at the school’s dental clinic. She’d had been complaining about a large gap that had developed between her front two teeth. Seven years previously, she got a tongue stud. And every day, for seven years, she pushed that stud up against her teeth.

The researchers say tongues are strong, and it makes sense that the force of “playing” will move teeth, even forcing them apart. The case was written up in the Journal of Clinical Orthodontics.

Tongue piercings have also been associated with infections, chipped or broken teeth, and gum trauma. And the patient? She got braces to push her teeth back together. Which probably didn’t look quite as cool as she thought the tongue stud was.

wall-rattling ???
这个是虾米意思哇？

桔子susanUID: 2754084

364# 婧榭居士
wall-rattling是轻微震动墙壁的意思，就是wall和rattling两个词的字面意思组合起来的（要多谢08版主的解释:) ）。wall就不解释了，rattling查了一下韦氏字典，有很多解释，个人感觉这个比较合适：: to make a rapid succession of short sharp noises <the windows rattled in the wind>
