However, HIV doesn't seem to be able to turn off the third form, HIV-C, and infects itself to get destroyed.

Your version may not be grammatically incorrect but it certainly is not idiomatic—viz. people do not normally say it this way. If you have American friends, you might want to check with them. I’m sure they will concur.

Well, that was a good try, close but no cigar!   :)

#1169 Original:

Some people seem to have a level of natural immunity against the AIDS virus, and researchers are looking at their genes to try to help an effort to make an HIV vaccine. That's according to research reported in a current issue of the journal Science. An international team of researchers examined almost 500 people infected with HIV, and identified the form of a gene that appears to have helped some of those people fight off the virus and delay the onset of AIDS. The unusual gene dosen't stop infection but it does keep the virus from proliferating. Ordinarily, the immune system identifies invaders and makers them for destruction, but HIV can usually disarm two forms of the gene involved in identifying the intruders. Those two forms are called HLA-A and HLA-B. However HIV doesn't seem to be able to turn off a third form HLA-C, and in fact itself (maybe the mistake of the DJ) do get destroyed. Researchers hope a vaccine might mimic HLAc's effect. Invesigators say that a series of future genome(OR genomic? OR genome map) studies will seek to pin point additional targets for HIV vaccines.

“a” or “the”, “the” or “a”, it is really a pain, isn’t it?  :)

....identifies invaders and makers them for destruction...

Are you sure?

Thanks for zhenzhen. I just remembered when I surfed the professors' homepages, it was "publications" instead of "publishings" which appeared on the screen :). "close but no cigar", again a nice phrase worth remembering.

for #1172
My view is:
However, HIV does not seem to be able to turn off a third form -- HLA-C and infected cells do get destroyed.

Steve’s diction (发音、口齿) is excellent and very easy to understand, always. He said “However HIV doesn't seem to be able to turn off a third form HLA-C, and in fact its cells do get destroyed.” The meaning is clear. He was telling us HIV cannot disarm HLA-C so it gets marked and its cells get destroyed by our immune system.

But let’s put that aside and try to use top-down to make sense out of your version. What does “infected cells” refer to? Without a referent (such as “its”) in the sentence, the term “infected cells” becomes very ambiguous—a sign of bad writing. This should raise a red flag right there. Perhaps it’s not that the writing is bad but that you are wrong.

However, for argument’s sake, let’s go on to guess. HIV’s cells or the patient’s cells?

The previous sentence tells us how the gene marks the virus for destruction, so the announcer had to be talking about HIV’s cells here. But isn’t it strange to say the virus’ cells are “infected”? Don’t we normally say “we are infected by a virus?” Have you heard people say “we infect a virus?”

Perhaps you think the infected cells are the patient’s cells that have been infected by the virus? This could not be true because why would Steve be talking about destroying the virus one second and then jump to talking about destroying the patient’s cells the next second with no apparent reason.

So you see there are lots of problems with your transcription. Can you or anyone else make sense out of it?

It’s checkmate for checkers! The 5000-year-old game has been completely solved and a checker-playing computer called Chinook cannot be beaten. That’s according to University of Alberta computer scientists, publishing in latest issue of the journal Science. The researchers spent almost two decades going through 500 billion billion possible checker’s positions, which is still an infinitesimal small fraction of the number of chess positions by the way. The checker effort included top players who helped research team program checkers’ rules of thumb into software that categorize moves as successful or unsuccessful. Then the researchers let program run on an average of 50 computers daily, some days the program ran over 200 machines while the researchers monitored the progress and tweaked the program accordingly. In fact, Chinook beat humans to win the checkers world championship back in1994. “But it has not become perfect”. That process is now done and the Chinook program has developed into a database that knows the optional move in any possible checkers situation. If a human opponent plays a perfect game, he or she can only hope for a tie.

Mosquitoes are a summer time menace, but also a marvel of mechanical engineering. They can stay stick to your skin, cling to a wall and even walk on water. Now a team of physicists from Canada and China has figured out how they do it. The trick is in their feet. First of all, the mosquitoes have tiny hooks on their tootsies which they use to latch on their skin and to hung on walls the same way geckos do, using hairy little foot pads that let them stick to surface like they’re wearing Velcro Socks. But it’s their water-walking that may be their most remarkable feat. To dance across a pond or stand on top of a puddle, mosquitoes use their super hydrophobic legs. These limbs are so phenomenally water repellent that each one could effectively support 23 times the insects’ weight. At least that is what the physicists discovered when they took a single mosquito’s leg, and measured the force needed to push it into a cup of water. The reason why the legs are so hydrophobic is because they are coated with tiny feather scales that are in turn covered by even tinier ribbing. So next time when you swat the skiiter, remember, you just whacked a wonder of nature.

I see. Sorry for taking up your time with explaining all these to me. I'll pay more attention next time.
