Scientists in Argentina have created the world's first cow with two human genes that will enable it to produce human-like milk.

    Genetic engineering was used to introduce the "mothers'milk" genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.

    As an adult, the cloned cow "will produce milk that is similar to that of humans", which will prove "a development of great importance for the nutrition of infants(婴儿)", said the institute. "The cloned cow, named Rosita ISA, is the first in the world with two human genes that contain the proteins present in human milk," said the statement.

    In April, scientists in China published details of research showing that they had created dairy cows which produced milk containing proteins found in human breast milk. But the Argentine team said the Chinese only introduced one human gene, while their research involved two,  meaning the milk will more closely resemble that of humans.

    “Our goal was to raise the nutrition value of cows'milk by adding two human genes, which do good to the immune system of infants,” said Adrian Mutto, from the National University of San Martin which worked with the institute.

    Cristina Kirchner, President of Argentina, said that the scientific institute made all Argentines proud. She also said that she had rejected the "honor" of having the cow named after her. "They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more proper to call it Rosita.”

    Languages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter-gatherers, small, tightly knit(联系) groups developed their own patterns of speech independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12,000 languages between them.   

    Soon afterwards, many of those people started settling down to become farmers, and their languages too became more settled and fewer in number. In recent centuries, trade, industrialisation, the development of the nation-state and the spread of universal compulsory education, especially globalisation and better communications in the past few decades, all have caused many languages to disappear, and dominant languages such as English, Spanish and Chinese are increasingly taking over.

    At present, the world has about 6,800 languages. The distribution of these languages is hugely uneven. The general rule is that mild zones have relatively few languages, often spoken by many people, while hot, wet zones have lots, often spoken by small numbers. Europe has only around 200 languages; the Americas about 1,000; Africa 2,400; and Asia and the Pacific perhaps 3,200, of which Papua New Guinea alone accounts for well over 800. The median number （中位数）of speakers is a mere 6,000, which means that half the world's languages are spoken by fewer people than that.

   Already well over 400 of the total of 6,800 languages are close to extinction (消亡), with only a few elderly speakers left. Pick, at random, Busuu in Cameroon (eight remaining speakers), Chiapaneco in Mexico (150), Lipan Apache in the United States (two or three) or Wadjigu in Australia (one, with a question-mark): none of these seems to have much chance of survival.

    Our eating habits are very important for good health and a strong body. There are times when most of us would rather eat sweets and ice-cream than meat and rice. Sweets and ice-cream are not bad if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite（食欲）. It is important for us to eat our meals at the same time each day. When we feel hungry, it is a sign that our body needs food. When we feel angry or excited, we may not want to eat. A long time ago, in England, some judges used to decide whether a man was telling the truth by giving him some dry bread. If the man could not eat the bread, it showed that he was telling lies. Although this seems very strange and rather foolish, it is indeed a very good way of finding out the fact. A man who is worrying about something has difficulty in eating anything dry. Because he is worrying, he loses his appetite and does not want to eat.

    Over 500 dogs being delivered to a butcher house were saved by a Chinese animal protection organization.

    The incident then triggered a debate among Chinese netizens about the necessity of pouring so much money and efforts into saving dogs.

    On Friday, a truck loaded with over 500 dogs were stopped by volunteers from animal protection organization on Jingha Expressway Beijing section. Beijing Times reported these dogs were being delivered to slaughter houses in the city of Changchun, northeast Jilin Province and would be eventually served on dinner tables. After negotiations with the truck driver, pet service provider Leepet Holding Corp. and a philanthropic foundation, Shang shan Foundation purchased these dogs, each paying 50,000 yuan. Dogs were then delivered to the headquarter of China Small Animal Protection Association (CSAPA), being taken care of and waiting for adoption.

    After the "dog saving mission" was reported, Chinese net users debate over whether saving dogs is worth so much efforts and money while there are still many poor and needy people in China lacking assistance. Some net users argue the "dog saving mission" is placing overattention to animals while lots of needy people are still left unattended. A microblogger "Xiaowulaitajie" said on China's twitter like website, weibo.com, "Dogs are saved, adopted and they attracted media spotlight. We'd better spend such money and take such efforts in helping the needy people." Another microblogger, Liluping, said "We poured such huge sum of money into saving dogs. I would rather the money was spent on disaster relief."

    Some applaud volunteers' actions and show eagerness of offering their helping hands to those saved dogs.

    Still many disapprove those "saving dogs" critics, but they argue that such act nonetheless promotes social progress.

    A microblogger named "broken bridge" said, saving dogs does not run counter to taking care of people. Such enthusiasm in public affairs will help raise social awareness in helping the needy.

    I think people and animals are created equal. Attention should be paid to people as well as animals.

    Many people all over the world enjoy an alcoholic drink, such as wine or beer, during dinner. Many people raise a glass of alcohol to celebrate a wedding or a birthday. And having drinks after work with friends and co-workers is called "happy hour".

    All these situations are considered "social drinking" because they happen at social events. But when does "social drinking" become problem drinking?

    According to the World Health Organization alcohol abuse kills 3.3 million people each year. That is six percent of all deaths around the world. And in a new report on alcohol use around the world, the WHO says alcohol can create dependency, or addiction, in some people. The report also warns that alcohol use can increase the risk of developing more than 200 diseases, including some kinds of cancers. And, the WHO says alcohol abuse can put people at greater risk of infectious diseases, such as tuberculosis(肺结核), pneumonia (肺炎)and HIV.

    WHO Mental Health and Substance Abuse Director Shekhar Saxena says the organization is concerned about drinking among young people between the ages 15 and 19. And it is most concerned about "binge-drinking", or an extended period of heavy drinking.

    The report concludes that worldwide 16 percent of drinkers over the age of 15 engage in binge-drinking, which is much more harmful than other kind of drinking and causes the most harm in terms of accidents, self-harm and harm to others. High income countries have the highest alcohol consumption and also the highest prevalence(盛行) of binge-drinking.

    The report also found that the highest rates of alcohol-linked deaths are in Europe, followed by the West Pacific and then the Americans. The report also finds Europe is the area with the highest alcohol use. Central and Eastern Europe are especially high.

    The World Health Organization suggests ways countries can protect people from alcohol abuse. These include increasing taxes on alcohol sales, raising the drinking age limit, and controlling the marketing of alcoholic beverages.
