Problem: 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."

question: Reggie Hilaire was a rookie cop on September 11, 2001. He worked at ground zero for 11 days beside his colleagues -- many of them, including Hilaire, not wearing a mask. He was later assigned to a landfill in Staten Island, where debris from the World Trade Center was dumped.

For about 60 days between 2001 and 2002, the New York police officer was surrounded by dust.

In 2005, Hilaire was diagnosed with thyroid cancer. He underwent surgery and radiation. Just months later his doctor told him he also had multiple myeloma, a blood cancer that multiplies the body's plasma cells to dangerous levels.

It's a cancer that usually strikes much later in life. Hilaire was 34.

More than 1,100 people who worked or lived near the World Trade Center on 9/11 have been diagnosed with cancer, according to the Centers for Disease Control and Prevention.

A few months ago Hilaire received a letter from the CDC's National Institute for Occupational Safety and Health, officially offering him medical insurance under the World Trade Center Health Program. About 1,140 people have been certified to receive cancer treatment under the WTC Health Program, a representative told CNN.

These are the first numbers released since the program was expanded a year ago.

In September 2012, federal health authorities added 58 types of cancer to the list of covered illnesses for people who were exposed to toxins at the site of the World Trade Center in the aftermath of the 9/11 attacks.

Dr. John Howard, administrator of the WTC Health Program, had said the year before that cancer treatments would not be covered by the compensation fund. At the time, he said there was inadequate "published scientific and medical findings" to link 9/11 exposures to cancer.
