The borehole is filled in with gravel around the pipe to help transmit highfrequency vibrations generated by particles within the slope. These vibrations pass up the tube and are picked up by a sensor on the surface.

D A different Life Form, a 一種不同的生命形式 39 Clone Farm克隆農(nóng)場(chǎng) Factory farming could soon enter a new era of mass production. Companies in the US are developing the technology needed to clone chickens on a massive scale1. Once a chicken with desirable traits has been bred or geically engineered2, tens of thousands of eggs, which will hatch into identical copies , could roll off the production lines every hour. Billions of clones could be produced each year to supply chicken farms with birds that all grow at the same rate, have the same amount of meat and taste the same. 工業(yè)化農(nóng)場(chǎng)很快會(huì)進(jìn)入一個(gè)大產(chǎn)量的新領(lǐng)域。s surface and much too cold to support life as we know it. 時(shí)至今日,盡管地球上的依賴液體水的微生物在甲烷里生長(zhǎng)良好或把它作為廢物排出,科學(xué)家在任何地方都沒有探測(cè)到這種生命的形式。他推測(cè)所有被研究者患喉癌的機(jī)率比其他癌癥低很多的原因是組織被酒精侵害到的部分少。 Luigino Dal Maso 和他的同事們研究了取自四項(xiàng)癌癥研究的 1,500個(gè)病例的飲酒習(xí)慣模式和另外 3,500個(gè)從沒患癌癥的成年人的飲酒習(xí)慣模式。研究者們可以直接測(cè)量,也可以在鉆孔中或者地表面上探測(cè)山坡形狀的變化。盡管如此,研究人員認(rèn)為,對(duì)于實(shí)現(xiàn)有效率的利用藻類產(chǎn)生氫這一目標(biāo),他們已經(jīng)邁出了第一步。奇若蒂在美國(guó)科羅拉多州的國(guó)家可再生能源實(shí)驗(yàn)室里對(duì)綠藻進(jìn)行研究。 is Belcher‘s team doing at present?

Consuming alcohol without food also increased by at least 20 percent the likelihood of laryngeal cancer. ―Roughly 95 percent of cancers at these four sites traced too smoking or drinking by study volunteers,‖ Dal Maso says. The discouraging news his team reports, is that drinking with meals didn‘t eliminate cancer risk at any of the sites. 在研究者分析了飲酒的總量后,他們發(fā)現(xiàn)和只在就餐時(shí)飲酒的人相比,在就餐時(shí)間以外灌下大量烈酒的人面臨至少 50%~80%的患口腔癌、咽癌和食道癌的危險(xiǎn)。 1.

During photosynthesis, plants normally make sugars or starches. But under certain conditions, a lot of algae are able to use the sunlight energy not to store starch, but to make hydrogen. Ghirardi says. For example, algae will produce hydrogen in an air free environment.
