Scientists in Argentina have created the world’s first cow to own two human genes that will enable it to produce human-like milk, which is matchless up to now. It is a breakthrough in the area of clone.

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 humans" in what will prove "a development of great importance for the nutrition of infants", it said in a statement.

"The cloned cow, named Rosita ISA, is the first one born in the world that owns two human genes that contain the proteins present in human milk," the statement said.

In April, scientists in China published details of research showing that they had created GM Holstein dairy cows which produced milk containing proteins found in human breast milk.

But the Argentine team says the Chinese only introduced one human gene, whereas their research involved two genes meaning the milk will more closely resemble that of humans.

Rosita ISA was born on April 6 and was delivered by Caesarean section because she weighed around 100 pounds, roughly twice the normal weight of Jersey cows.

Adrian Mutto, from the National University of San Martin said "Our goal was to raise nutritional value of cows’ milk by adding two human genes, the protein lactoferrin and lysozyme, which can provide newly-born babies with anti-bacterial and anti-viral protection."

Cristina Kirchner, President of Argentina, said that the scientific institute "makes all proud.” She also revealed 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 appropriate to call it Rosita.”

A drunken burglar in the Orrell Park area of Liverpool, ended up leaping out of a window after a 10-year-old girl asked him to prove he was a superhero.

The drunken thief who pretended he was Superman to stop a child raising the alarm has been caught after he leapt from the apartment building in his pants to make the girl convinced.

Thief Ethan Adamson, 25, told police that he had broken into a fifth-floor flat after a drinking party, believing it was empty.

But he was horrified when the owner’s 10-year-old daughter woke up while he was there.

From his hospital bed, the thief told reporters, “To keep her quiet, I told her I was really Superman and I’d soon be flying off back to my secret headquarters.”

“She called my bluff (向…摊牌) and told me, ‘If you’re Superman, show me you can fly or I’ll scream’.”

“I had no choice so I stripped to my pants to look more like a superhero and went to the window. I saw another roof below and I thought I could make it but it turned out to be a lot further down than thought. I know it doesn’t make sense but it did to me when I was drunk.”

Police later found him on the roof in just his yellow pants, covered in cuts and bruises(淤青) after a neighbor heard his cries of pain.

He now faces seven years behind bars for burglary.

Police spokesman Frank Armado said, “He was in quite a serious state and couldn’t move until we got up there using ladders. He was treated for his injuries and we got him some fresh clothes, before taking him to hospital where he is being kept under guard until he is well enough to be arrested.”

When a New Yorker was hiking in Europe, his Swiss friend kept saying “Listen to that!” but he didn’t hear anything.
