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.”

    From July to October every year, about a quarter of the world's blue whales feed in the Pacific Ocean off the coast of California. But the whales currently face a major threat in their favorite feeding area. Ships carrying cargo (货物）sail in the same area at the same time. All too often, the whales' paths and the ships' travel lines overlap (重叠), and a ship will hit a whale.

    According to a new study, these ship strikes have become a serious threat to the overall population of the world's blue whales. Only about 10,000 of the creatures still exist worldwide. Blue whales are the largest known animals ever to live on Earth. Even so, if hit by a container ship, a blue whale will likely die from its injuries.

    In 2007 alone, large ships killed five blue whales in the waters off San Francisco and Los Angeles, California. The National Oceanic and Atmospheric Administration (NOAA) says that because there are so few whales already, losing three to five from the California whale population every year is a significant loss. “The estimated population of blue whales in this part of the Pacific is 2,500”, says Sean Hastings, a NOAA analyst. “So every whale counts toward this species moving off the endangered-species list.”

    Now, marine scientists must figure out how to protect the whales from the giant container ships. One very simple program is already under way in the Santa Barbara Channel, a waterway that separates mainland California from the nearby Channel Islands.

    The Channel Islands National Marine Sanctuary has asked large container ships passing through the area to voluntarily slow down. Sailing slower will allow the ships‟ crew (船员）more time to change course before hitting a whale.

    Several of the world's largest shipping lines are set to participate in the new program. For every ship that passes through the Santa Barbara Channel at or below the reduced speed of 12 knots (海里/小时）, the company that owns the ship will be paid $2,500.

    Travel information

    Bath will be very crowded on Saturdays，so we recommend that you start earlier for your journey considering the busy traffic.

    Find out about travelling to Bath by car，train, coach and plane. The main train station is Bath Spa, the closest airport is Bristol, and there is quite a lot of parking but it fills up quickly. National Express has coaches to and from Bath.

    Parking

    The closest car park to the Assembly Rooms (the starting point for the Promenade) is located in Charlotte Street, which is divided into several sections. Parking in the top section means the shortest walk to the start in the Assembly Rooms.

    Park and Ride will be very busy on Saturdays with visitors to the city. Please allow plenty of time to park and catch the bus, and we suggest at least one hour from parking the car to getting into the city center plus walking time from the bus stop to the Assembly Rooms.

    Accessibility

    For accessibility, please see the list. Most places are a least partly accessible. If using a wheelchair, please advise the Box office so that suitable arrangements can be made for your comfort.

You may think that the story of Pygmalion (《卖花女》, 1913) — in which people are judged by the way they talk — is something that only existed in the days of British high society. But thanks to etiquette (礼仪) expert and author William Hanson, we realize that little has changed during the past 100 years.

    In a BBC radio program, Hanson released a list of common words used in British English that could reveal whether a person is "common" or "fashionable".

    And yet here comes the interesting part: While some of us might go through life using fancy words, dressing in ways that make us appear more well-off than we really are, there are wealthy people in the world who try to hide their riches because they want to be seen as "normal" instead of "showy".

    Beatrice, for example, is a New Yorker who inherited (继承) millions of dollars. She told The New York Times that she has a habit of removing the price tags (价签) from her clothes so her house staff don't see them and feel uncomfortable.

    "We don't want that 'Wow'." said Scott, also a New Yorker, who had just inherited over $50 million. "We're just not the type of people who wear it on our sleeve."

    I used to be crazy about the hunting season. The excitement of waiting for a prey(猎物)and the pride of showing off the kill fascinated me. However, everything changed after that cold morning.

    Early on that day of the late fall, I set off alone for the woods, packing a gun, a bottle of hot coffee and three thick sandwiches. After finding the fresh deer's tracks in the snow, I settled down behind a little bush.

I sat there for about an hour. It was then that I saw him. A deer, a big beautiful deer! There was no cover nearer to him than 30 yards. Surely I couldn't miss! I waited for him to realize I was there. I waited for him to be shocked and run away. But he fooled me completely. He came towards me! He was curious, I suppose, or maybe he was stupid—how else can you explain it? Well, that deer walked right up to where I was sitting. Then he stopped and looked at me!

    What happened next is hard to believe, but it's true. And it all seemed quite natural. Just as when a friendly young deer comes near you, I reached up and scratched his head. And he liked to be scratched. In fact, he practically asked for more. Then, I fed him my sandwich! Yes, I know what a deer eats, but that deer ate my sandwich. Well, he finally went his way, down the hill and up the deer trail. Shoot him? Not me. You wouldn't have either, not after that. I just watched him go.

    When I was about half way back, I heard two shots, followed by a dull slam(撞击)a few seconds later. Those two shots usually mean a kill. I had forgotten there were other hunters that day.

    Those hunters would never know they could have scratched his head.

    I became a magician by accident. When I was nine years old, I learned how to make a coin disappear. I'd read The Lord of the Rings and risked coming into the adult section of the library to search for a book of spells (魔法) — nine being that curious age at which you're old enough to work through more than 1, 200 pages of mysterious fantasy literature but young enough to still hold out hope that you might find a book of real, actual magic in the library. The book I found instead taught basic sleight-of-hand (戏法) technique, and I devoted the next months to practice.

    Initially, the magic wasn't any good. At first it wasn't even magic; it was just a trick — a bad trick. I spent hours each day in the bathroom running through the secret moves in front of the mirror. I dropped the coin over and over, a thousand times in a day, and after two weeks of this my mom got a carpet sample from the store and placed it under the mirror to eradicate the sound of the coin falling again and again.

    I had heard my dad work through passages of new music on the piano, so I knew how to practice — slowly, deliberately, going for precision rather than speed. And then I tried the illusion (错觉) in the mirror and an unbelievable scene took place. It did not look like a magic trick. It looked like a miracle. I knew that I had got what I wanted.

    One day I made the performance on the playground. We had been playing football and were standing by the backstop in the field behind the school. A dozen people were watching. I showed the coin to everyone. Then it disappeared. The kids screamed. They yelled, laughed, scrambled away. Everyone went crazy. This was brilliant.
