Here's what scientists think happened, oh, about 100 million years ago. There was the 3-star system,  the three linked stars were strolling through the galaxy, but got too close to the giant black hole at the center. The hole swallowed one of those stars and hurled away the other two. Those two careening stars merged to form one super hot incredibly fast moving blue star which is now on the very outskirts of the Milky Way. And here is how scientists came up with the dramatic tale which they just published in the Astrophysical Journal Letters. They discovered what they called a hypervelocity star which moves three times faster than our sun does through the galaxy.

According to new information provided by the Hubble Telescope, the star originated deep within the Milky Way. The scientists use the Hubble to figure out the direction of the star's travels and the distance from the Galactic Center. Along with the star's mass, age and speed, its unusual attributes give rise to the idea that once star was swallowed and transferred its momentum to the other two which transformed into a blue super star, hurtling through the galaxy faster than a speeding sun.

Declining frog populations are considered an indicator of environmental damage. But new research finds that frogs might be doing even worse than we thought. Because the volunteers who count frogs by their sounds may be overestimating.

The North American Amphibian Monitoring Program is the country’s largest frog-counting system. Volunteers listen for frogs, identify the species, and give population estimates. They’ve been doing this for over a decade.

Ted Simons from North Carolina State University and colleagues put recordings of frogs, like this wood frog, [Wood Frog sound] in the field to test the volunteers. They call it Ribbit Radio.

Many volunteers ended up with false positives—they named frog species whose calls weren’t being played. So there may be fewer frogs, or less variety, than the surveys suggest. The results appear in the journal Ecology.

Simons is working with the U.S. Geological Survey—in charge of the amphibian monitoring—to account for these false positives, and to better train the volunteers—so they don’t write down “chorus frog” [Chorus Frog sound] when all there really was were pickerel frogs. [Pickerel Frog sound] Apparently, it’s not easy being green, for humans either.

不好意思哈我是托福新人，能不能麻烦大家告诉我，啥叫听抄。。。 是边听边写然后对照原文吗？听一句，暂停，写，然后再听，再写？还是不间断地听下去，能写多少写多少，然后再反复？
谢谢各位！

green的意思指人的话是新手，这里一语双关，green指青蛙的绿色，就是说它们已经减少了，境遇不佳，人的话指volunteers，他们犯了计算和识别的错误。

Transgenic Canola Plants Break Free of Farm

One of the concerns about working with genetically modified crops has been that vegetation growing in agricultural 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 had received genes making them resistant to herbicides, such as the weed killer Roundup. Researchers collected and tested 406 canola plants along thousands of miles of state roads. They found 347 carrying at least one resistance gene. There were also indications that the inserted genes have been passed on to new generations, producing some plants in the wild with multiple transgenes. The findings were presented on Aug, 6th at the annual meeting of the ecological society of america in Pittsburgh. The transgenic canola plants are not about to take over 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. Any answers they find will likely affect the future biotechnology regulation.

Here’s a possible blood pressure remedy. But it’s only for those who can stand the heat. It’s capsaicin, the “active ingredient” in peppers like habaneros that should probably be sold by prescription only. While lips burn and eyes water, blood vessels actually relax, thanks to increased production of the signaling molecule nitric oxide. In rodents, anyway.

For seven months, researchers in China fed a steady diet of capsaicin to rats bred to be hypertensive. Long-term consumption of the chemical substantially lowered the rats’ blood pressure. The results appear in the August issue of the journal Cell Metabolism.
Previous research found mixed results with capsaicin, but those studies only looked at short-term effects. Human trials are needed, but there’s already a clue. Some 20 percent of people in northeastern China have high blood pressure. But the southwest—where hot peppers are a dietary staple—has a much lower incidence, half in some places.
Human studies could also confirm whether the habanero, as legend has it, can cause hearing loss. Allegedly so that diners don’t have to listen to their own screams.
