Talk about a cold case. Researchers in Italy andSwitzerland (have与后面的词连读了) announcedthat they have determined the cause of death for the iceman. He is(that) incredibly well preserved frozen mummy thatwas sticking out of the glacier in the Alps near the ItalyAustria(Italian - Austrian) border about 10,000 feet up back in 1991.He’s been lying there for about 5,000 years. In 2005 the mummy, sometimesreferred to as Frozen Fritz, was subjected to non-invasive multislice computedtomography often called CT scan. In a paper published this week in the Journalof Archeological Science online the scan found a lesion in the left subclavianartery that’s the big blood vessel underneath the clavicle or collarbone. Thelesion was apparently caused by an arrow hit that’s still large in the iceman’sback. Modern records of such injuries indicate that the iceman survived foronly a short time after suffering this injury. There is no statue of limitationon murder and this killer is still at large. Global warming may get reveal theperpetrator shooter dying. Glacial(should a dying glacier)set them free.
很赞kelediguo啊，听得很不错，呵呵，学习~~

The black widow spider is famous for its interesting mating habit, but its silk especially what is called dragline silk is pretty specially too. Dragline silk is one of the seven kinds of silk that individual spider produces. It is the silk that provides the structural foundation of the spider’s web and support the spider’s body as it moves around. Turns out that black widow dragline silk is super strong and stretching compared with most other silks, which makes it an attractive item for human’s to try to copy and modify for using light weight but strong clothing or even body armor. Well the effort to manufacture spider so got bush this week with the publication of DNA sequences of the genes that code for two of the key proteins that make up the black widow dragline silk. The research appears on the June 30th online edition of the Journal of Public Library of Science warn, as one of the researchers said, there is nothing as quite good yet as natural dragline silk. But we should get closer now we have the full genetic recipe.

明天开始三天要出差，所以只能在回来后，也就是16号补上音频，至于之前的听抄修改我也会补上。最近很忙，请大家见谅。forerunner，要坚持哦，加油！:loveliness:

Researchers have identified and sequenced the genes for key proteins in black widow spiders' super-strong dragline silk, bringing us a step closer to being able to make it ourselves for use in various materials.

The Black widow spider is famous for its interesting mating habits, but its silk is specially what is called dragonline silk, which is pretty special too. Drongonline silk is one of 7 kinds silk that an individual spider produces. It is the silk that provide the structural foundation of the spider’s web and support the spider’s body as it moves around. Turn out to black widow gragonline silk. It is super strong and stretchy, compared to most other silk, which make it an attractive item for human to try to copy and modify, for using light weighted clothing or even body armor. Well the effort to manufacture spider silk got a boost this week. With the publication of DNA sequences of that genes that code for two of the key proteins that make up the black widow dragonline silk. The research appeared in June 13th on line edition of the Journal of Public Library Science one. As one of the researchers said, there is noting quite good yet as natural gragonline silk, but we should get a lot close now we have the full generic recipe.

Veterans, especially wounded ones, also carry psyche(psychic) scars of their war experiences. Those mental wound(wounds) can sometimes be fatal. A new study finds the former military personnel are twice as likely to commit suicide as a(other) people who never served. The study appears on(in) the July issue of the Journal of Epidemiology in Community Health. Those of the highest risk were veterans who were sidelined from home, work or leisure activities because of the health issues. So doctors, friends and family members should be on extra alert for signs of suicide(suicidal) intentions in soldiers returning from Afghanistan and Iraq, especially wounded ones. The researches followed over 300,000 veterans for twelve years. Some of the vets in the study went all the way back to the World War I with the more recent vets having served at the first Iraq war in the early 90s. Some quirky findings in the study overweight veterans were less likely to take their own lives than man of normal weight, but vents who were white, older, better educated, and never married were more likely to take their own lives than were people in the general population.

Dragline silk is one of the seven kinds of silk that an individual spider produces. It’s the silk that provides the structural foundation of spider’s web and supports the spider’s body as it moves around. It turns out that black widow dragline silk is super strong and stretchy compared to most other silks, which makes it an attractive item for humans to try to copy or modify for using light weight but strong clothing or even body armor. Well, the effort to manufacture spider silk got a boost this week with the publication of DNA sequences of the genes that code for two of the key proteins that make up the black widow’s dragline silk.

As one of the researchers said, there’s nothing quite as good yet as natural dragline silk but we should get a lot closer now that we have the full genetic recipe.

June 11.. keep on trying..

Cellphone is(Cellphones are) great, except for one problem. If you forget to recharge the battery, you might get a call without a working phone. But hey, if that phone signal can follow you all over the place, whycan't someone just beam some electricity add(at) your phone? Well, researchers at MIT have taken a step towards making the matter reality. They call it wiretricity (WiTricity)for wireless electricity. And they were able to switch on a 60 Watt light bulbfrom a power source 7 feet away without any wires. They did the trick by using coupled resonance, which works because two objects with the same resonance frequency exchange energy very efficiently. Think of the opera singer who can make a wine glass explode (我晕眩了 @@). The MIT system relies on magnetic fields. A copper coil attach to a power source; fill the space around it with a magnetic field that oscillate at a particular frequency. A second receiving coil tunes that frequency and converts the magnetism back to electricity. So someday you might leave the house with a spent cell phone and watch a(it) charge-up as you walk down the street.
