This (no in) just in: diamonds are not likely to form in the atmosphere of Gas Giants, planets such as Uranus and Neptune. Now if I know(I don't know) you, you probably never thought to look for diamonds in the outer reaches of our solar system, but that’s what physicists were recently contemplating. In the carbon-rich atmospheres of these giant planets, they figured diamonds might just rain from the sky, or at least crystallize there. But in an upcoming issue of the journal (no of) Physical Review Letters, physicists from Amsterdam, Netherland say “no way”. According to their calculations, the temperatures and pressures present in and around planets like Uranus would be more suitable for generating graphite. Yes, the atmosphere around our outermost planets could be filled with pencil lead. But wait, there is more. The same scientists contend that white dwarfs which are the end stage of the great majority of stars or galaxy are variable diamond factories. Conditions there are perfectly suitable for transforming carbon atoms into sparkling gems. Indeed three years ago, astronomers spotted a white dwarf whose core appeared to be a diamond 2500 miles wide. Now that would make an engagement ring. It would break your finger and your bank account.

Don't worry about "worry" because it wasn't there in the first place.

I guess you guys did not pay attention to #1219 by yyhwzc. He got it right already.

This just in: diamonds are not likely to form in the atmosphere of gas giants--planets such as Uranus and Neptune. Now I fan you. You’ve probably never thought to book for diamonds in the outer reaches of our solar system. But that’s what physicists were recently contemplating. In the carbon-rich atmospheres of these giant planets, they figured out diamond might rain from the sky, or at least crystallize there. But in an upcoming issue of Journal Physics Review Letters, physicists from Amsterdam Netherlands say no way. According to their calculations, the temperature and pressure present in and around planets like Uranus would be more suitable to generate graphite. Yes, the atmosphere around outmost planets could be filled with pencil graphite. But wait, there is more. The same scientists contend that white dwarf, which are the end stage of the great majority of starts in our galaxy, are variable diamond factory. Conditions there are perfect suitable for transforming carbon atoms into sparkling gems. Indeed 3 years ago, astronomers spotted a white dwarf core appeared to be a diamond 2500 miles wide. Now that it would make an engagement ring, it would break your finger and your bank account.

Don't give up. There are still problems with the script of July 27th.  :)

我还在想去哪找听力原文呢，谢谢LZ，我也要好好努力了:)

oops, I tried but failed!

The same scientist contended that white dwarfs, which were the end stage of great majority of stars in our galaxy, are veritable diamond factories.

question: Now that would make an engage ring. It will break your finger and your bank account.
I guess if: Now (if) that would make an engage ring, it will ..., that would be more smooth and meaningful.

PS: please refer to #1230 coz most followers neglected the "an" the "s" errs.

The early as known practical prosthesis is an artificial leg dating back to 300 B.C.. But British researchers are checking out a significantly older wood and leather fake toe, found still attached to its mummy in the Cairo Museum. They wanna see if it served as more than a cosmetic purpose and perhaps was important in helping its owner, you know, "walk like an Egyptian". Sorry. The in mummy has been informally dubbed "toting common". Sorry again. What's particularly interesting about the false toe is that it's articulated in the chose science of wear. So it may indeed have helped the woman who wore it walk better. And it dates from somewhere between 1000 B.C and 600 B.C., making it older than the so-called "Roman Capua Leg" which was made of bronze and survived the punic wars but didn't make it through World War II. The leg was destroyed during the bombing of London. Anyway, scientists have made an exact duplicate of the mummy's digit and are testing it on volunteers who are missing a right big toe to see whether it's really functional. That research is a foot.
