question:
Paragraph: A 38-year-old man from Zunyi city died last Thursday, Xinhua said, citing health authorities in Guizhou. Xinhua said it was the first human case of H7N9 in Guizhou this year. Last Friday, China said a 38-year-old man in eastern Fujian province died from H7N9. The World Health Organisation (WHO) said last week that seven more people in China had been found to be infected with the H7N9 strain of bird flu in the previous week, taking to around 150 the total number of cases so far. The H7N9 bird flu emerged last year in China and has infected around 150 people there and in Taiwan and Hong Kong, killing at least 45 of them. Experts say there is no evidence as yet of any easy or sustained person-to person transmission of the strain. But an early scientific analysis of probable transmission of the new flu from person to person, published last August, gave the strongest proof yet that it can at times jump between people and so could cause a human pandemic. The WHO said the source of the human infections was still being investigated. It stressed that it does not advise any special screening for people going in and out of China, nor does it recommend any travel or trade curbs. Claim: China reports second H7N9 bird flu death in a week.
answer:
China reported one more death from the H7N9 strain of bird flu in southwestern Guizhou province, state news agency Xinhua said on Monday, in the second death from the virus in the past week.

question:
Paragraph: After more than three hours of debate, lawmakers in parliament's upper house voted on Tuesday for a change in the law to allow the treatments, echoing a positive vote in the lower house earlier this month. The treatment, called mitochondrial transfer, is known as "three-parent" in vitro fertilization (IVF) because the babies, born from genetically modified embryos, would have DNA from a mother, a father and from a female donor. Although the techniques are still at the research stage in laboratories in Britain and the United States, experts say that now legal hurdles have been overcome, Britain's first 3-parent baby could be born as early as 2016. Mitochondrial transfer involves intervening in the fertilization process to remove faulty mitochondrial DNA, which can cause inherited conditions such as heart problems, liver failure, brain disorders, blindness and muscular dystrophy. Mitochondria act as tiny energy-generating batteries inside cells, and around 1 in 6,000 babies around the world are born with serious mitochondrial disorders. Responding to the vote, Jeremy Farrar, director of the Wellcome Trust medical charity commended lawmakers for a "considered and compassionate decision". "Families who know what it is like to care for a child with a devastating disease are the people best placed to decide whether mitochondrial donation is the right option," he said. Mark Downs, chief executive of the Society of Biology, hailed "a great day for UK science" and said the landmark decision "will ensure mothers who carry faulty mitochondria can have healthy children free from the devastating conditions." But Marcy Darnovsky, director of the campaign group The Center for Genetics and Society, called the move a "historic mistake" which turns children into biological experiments and will "forever alter the human germline". "The techniques ... are relatively crude and will not in and of themselves create so-called designer babies," she said. "However, they will result in children with DNA from three different people in every cell of their bodies, which will impact a large range of traits in unknowable ways and introduce genetic changes that will be passed down to future generations." Claim: Britain becomes first nation to legalize three-parent babies.
answer:
- Britain will become the first nation to legalize a "three-parent" IVF technique which doctors say can prevent some inherited incurable diseases but which critics fear will effectively lead to "designer babies".

question:
Paragraph: It's widely known that languages evolve as societies develop and change, but the sounds we utter are also shaped, literally, by the placement of our jaw and that is influenced by how we chew our food, researchers report Thursday in the journal Science. Language study often focuses on cultural factors, "but our work shows that language is also a biological phenomenon you can't fully separate culture and biology," said Balthasar Bickel, a linguist at the University of Zurich and co-author of the new study. The researchers analyzed Stone Age and modern skulls and created simulations of how different jaw placements allow our mouths to make different sounds. They analyzed a database of roughly 2,000 languages more than a quarter of languages in existence today to identify which sounds were more and less frequently used, and where. Languages spoken by groups with hunter-gatherer societies in their more recent past are far less likely to use consonants used by longtime farming societies, the study found. "Our anatomy actually changed the types of sounds being incorporated into languages," Noreen von Cramon-Taubadel, an evolutionary anthropologist at the University of Buffalo who was not involved in the study, wrote in an email. Before societies cultivated crops and learned to cook food, early humans chewed tough raw meat which was hard work on our jaws and teeth. Stone Age adult skulls don't look like modern skulls. These older skulls have upper and lower teeth closing directly on top of each other whereas today most people have some degree of overbite, with the front teeth extending in front of bottom teeth when the mouth is closed. "If you are raised on softer foods, you don't have the same kind of wear and tear on your bite that your ancestors had, so you keep an overbite," said Bickel. Eating softer foods not only sets the jaw in a different fashion, but also changes which sounds are easily pronounced. In particular, it becomes much easier to say "f and "v," which linguists call "labiodental" sounds. (Try it. Put your upper and lower incisors or "front teeth" directly on top of each other and try say "favor." It's difficult.) The researchers looked closely at 52 languages from what is called the Indo-European language group including dialects spoken from Iceland to India and charted how the "f and "v sounds appeared in a rising number of languages over time. As more societies developed agriculture and traded in raw meat for softer fare whether it's cooked meat and potatoes, or rice and stewed vegetables these sounds became more common, the researchers found. "New sounds get introduced into languages, and then are more widely adopted," said Steven Moran, also a linguist at the University of Zurich and co-author of the paper. The notion that agriculture shaped language was first suggested decades ago by American linguist Charles Hockett, but he did not attempt to prove it. Elan Dresher, a linguist at the University of Toronto who was not involved in the study, commended testing Hockett's theory, but said the research could be fine-tuned by looking at historical reconstructions of languages, rather than using language databases to make comparisons. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education.

answer:
The way most of us speak today is shaped in part by how long ago our ancestors gave up chewing tough, raw meat.
