A top Chinese biology lab has ascribed the H7N9 avian influenza to genetic reassortment of wild birds from east Asia and chickens from east China.中国某生物实验室已经追踪到H7N9禽流感病毒源,该病毒的产生是因为东亚野鸟与华东家鸡基因重组。The researchers from the Chinese Academy of Sciences found that no genes in H7N9 were traceable to pigs, thus excluding pigs as intermediate hosts for the deadly new strain of bird flu.中国科学研究院的专家未在猪身上追踪到H7N9病毒,因此可以排除猪作为本次禽流感病原体的可能性。 Article/201304/234368

Although fish do not sleep, most change their behavior at night. The tips given here can help you catch your limit after the sun goes down.尽管鱼不睡觉,然而大部分鱼在夜间的行为会发生变化。以下建议可以帮助你在太阳下山之后钓鱼。You Will Need你需要Timing选择时间Shallow water浅水Artificial bait人造诱饵Needle-nose pliers钳子Flashlights手电筒Insect repellant驱虫剂Boat (optional)小船(可选)Steps步骤Step 1 Time your fishing1.选择钓鱼时间Start fishing after sunset or 1 to 2 hours before sunrise. The best time of year for night fishing is between the months of April and October.日落后或日出前1至2小时开始钓鱼。一年里夜间钓鱼最好的时间是4月至10月之间。If you will be fishing from a boat, make sure it is running properly. You don#39;t want to get stuck on a lake, day or night.如果你是乘坐小船钓鱼,确保运转正常。无论是白天还是晚上,你肯定不想船只搁浅。Step 2 Fish in shallows2.浅水中钓鱼Fish near reefs and ledges, or within casting distance of shallows. Retaining walls, docks, and bush areas are good places to find night-feeding fish.在礁石或岩石附近,或者浅滩处钓鱼。护城墙,码头和灌木丛都是寻找夜间觅食的鱼儿最好的地方。Fish that are active at night often leave the muddy bottoms of lakes and streams at night to search the shallows for food.夜间活跃的鱼通常会离开湖水或溪流泥泞的底部,到浅水中寻找食物。Step 3 Use artificial bait3.使用人造诱饵Use artificial bait. Most fish that are active at night have keen senses of touch and taste, but weak sight, and are very sensitive to slight movements in the water.使用人造诱饵。大多数夜间活跃的鱼触觉和嗅觉都很灵敏,但是视觉却很弱,对于水的轻微运动非常敏感。Step 4 Carry needle-nose pliers4.携带钳子Carry a pair of needle-nose pliers to remove hooks from the mouths of fish in the dark.携带一副尖嘴钳,这样可以在黑暗中取掉鱼嘴巴上的鱼钩。Step 5 Bring flashlights5.携带手电筒Bring flashlights or a headlamp and spare batteries.携带手电筒或头灯,以及备用电池。Step 6 Take insect repellant6.携带驱虫剂Take along plenty of insect repellant.

Iconic #39;Got Milk?#39; slogan gets replaced The iconic tagline behind the milk industry, ;Got Milk?,; has been replaced with ;Milk Life; in hopes of higher sales.-Well, you know, you have to change it, because it#39;s all about rebranding. And then you have milk sales suddenly declining, but they had to come up with something new. But it#39;s crazy to think that these two words Got Milk could have got such an impact on American pop culture. Obviously, we all remember those ads, beautiful women back in the early 90s, wear the milk mustaches around their lips. N* being one of them. Also David Beckham, he was pictured as well. We also had Alten John. With that types of celebrites that was used very widely. Harrison Ford was included, too, Murande Lamber. But the idea of the campaign was really to push people, Hey, listen, you know, successful cool people, celebrities are drinking milk. You should, too. But as I mentioned milk sales is steadily declining, so the ads come up with something new. The new campaign is referred to Milk Life. So it#39;s less focused on celebrities, more on the nutritional content, focusing on the protein of the milk, less about the celebrities. The idea is that really will help the milk sales pick up.-Wait, you said Milk Life? Like a life? Milk Life.-Milk Life, OK. That#39;s it. Milk Life.-OK, I#39;m just meritting, meritting on it. See, if I like it. As we talk milk, I know prices of milk going up across the country.-Yeah, exactlly, let me just show you what the milk prices are right now. They currently stand at 3 dollars and 55 cents a gallon. They#39;ve been spiking steadily since back in September when they were 3 dollars and 42 cents a gallon. So a couple of factors are going to this. First of all, the demand. As people make more money, they tend to spend more in the grocery store. And obviously, demand tends to push the prices up, but also another factor that#39;s kind of link to demand as well. It#39;s really exports. Milk, more and more milk is being exported. More and more dairy products are being exported. Exports are all-time high. That is actually, ovbiously affecting demand, which pushes prices high again. And then there#39;s a wild cause, with the draught in California. Obviously, the cows need water and pasture. Obviously, we have a draught, and that might actually impact milk prices later down the line. /201402/277816
