A National Academy of Sciences report (.pdf) last year said that while the milk and meat from cloned animals would not likely make anyone sick, more research should be performed. Now, a new US-Japan study published in the April 11 online issue of the Proceedings of the National Academy of Sciences says that milk and meat from cloned cattle does indeed appear to meet industry standards and appears to be safe for human consumption.

As BBC News reports, the scientists, led by Professor Jerry Yang from the University of Connecticut, compared the produce from two beef and four dairy clones, all derived from a single Holstein dairy cow and a single Japanese black bull, with the produce from normal animals of similar age and breed.

The meat was analysed against more than 100 physiological, tissue and cellular components, while the milk was analysed for protein, fat and other variables. No significant differences between the produce of cloned and normal cattle were found. Higher levels of fat and fatty acids were found in the cloned cow meat, but they still fell within beef industry standards.

While the study showed the cloned produce to be within the range approved for human consumption, the scientists stressed that the research was still in its early stages. Their findings, they said, provide “guidelines” for further research with larger numbers of clones from different genetic backgrounds.

Cloning livestock may one day increase yields by copying those animals that are especially productive and especially resistant to disease.

“The milking production levels in the US are three to four times higher than levels in China; maybe even five times or more compared to cows in India and some other countries,” Professor Jerry Yang told BBC News. “Therefore cloning could offer technology for duplicating superior farm animals. However, all the products from these cloned animals must be safe for human consumption. …and it is a major issue for scientists to provide a scientific basis for the data and information to address this question.”

As USA Today reports, there is currently no law governing the sale of meat or milk from the estimated 1,000 to 2,000 cloned farm animals in the USA. But since 2003, the US Food and Drug Administration (FDA) has asked producers to voluntarily keep the meat and milk of these animals, and that of their offspring, out of the food supply.

Wired News reports that companies like ViaGen and Cyagra, which offer livestock-cloning services, have also been waiting for several years for a final say from the FDA.

“For the United States agricultural industry, (cloning) can reduce the number of cows necessary for milking,” said Jerry Yang “They can have a pleasant environment and produce even more milk.” He also said that cloning cattle from the United States, where genetic breeding is more advanced, could save developing countries 50 years of breeding.

The idea of cloning animals for human consumption is not without its critics. First, there are the welfare concerns, as most cloned animals do not make it to term before being born, and many of those that do are born deformed or prone to illness. The Humane Society of the United States has asked for a ban on milk and meat from clones for just this reason. Second, there is still the concern that healthy clones may have subtle defects that could make their food products unsafe to eat.

As the Washington Post reports, some critics are asking why it is necessary to clone cows that produce huge amounts of milk when surpluses, rather than shortages, are the main problem facing the U.S. dairy industry today.

American film director John Hughes, noted for such movies as Sixteen Candles, Pretty in Pink and The Breakfast Club, died Thursday due to a heart attack.

A statement, released by his representative, said that he experienced the heart attack while on a morning stroll in Manhattan, New York. Hughes was born on February 18, 1950 in Michigan. He started his career as an advertising copywriter in Chicago. By the end of the 1970s he was a frequent contributor to the National Lampoon magazine.

In the 1990s, he made the Home Alone series, which became a box office sensation and turned Macaulay Culkin into a star.

In recent years, Hughes stepped back from the movie industry to spend more time with his family. He is survived by his wife of 39 years, Nancy, two sons and four grandchildren.

They are cheap, useful, and very plentiful, and that is exactly the problem, according to researchers. A report issued on Feb. 23 by a cadre of environment and economics researchers suggested that Kenya should ban the common plastic bag that one gets at the checkout counter of grocery stores, and place a levy on other plastic bags, all to combat the country’s environmental problems stemming from the bags’ popularity.

Wednesday, February 23, 2005A compound in the common daisy-like plant feverfew kills human leukemia stem cells and could form the basis for newer, more effective drugs for the disease.

American researchers at the University of Rochester Medical Center in New York say that it could take months to develop a useable drug from the compound, parthenolide.

However, they are working to do so with chemists at the University of Kentucky who have identified a water-soluble molecule with the same properties. The US National Cancer Institute has also accepted the work into its rapid access program, which aims to speed experimental drugs into human clinical trials.

“This research is a very important step in setting the stage for future development of a new therapy for leukemia,” says Rochester researcher Craig Jordan. “We have proof that we can kill leukemia stem cells with this type of agent, and that is good news.”

Parthenolide appears to target the roots of myeloid leukemia, stem cells, while current treatments including the relatively new drug Gleevec don’t. So, “You’re pulling the weed without getting to the root,” says Jordan.

Used for centuries to fight fevers, inflammation and arthritis, feverfew earned interest from the Rochester researchers after other scientists showed that it could prevent skin cancer in animal models.

So the researchers investigated how a concentrated form of the plant component parthenolide would affect leukemia cells and normal cells.

Comparing the impact of parthenolide to the common chemotherapy drug cytarabine, they found that parthenolide selectively killed leukemia cells while sparing normal cells better.

While the findings suggest that parthenolide is a good starting point for new drugs, people with leukemia aren’t being encouraged to take high doses of feverfew as they could not take enough of the remedy to halt the disease.

The research is reported in the journal Blood.

Fire broke out on Friday morning and destroyed the bottom two floors of a six-story hospital in Miryang, South Korea, killing at least 37 people, most of them elderly. More than a hundred injuries were reported, with eighteen people in critical condition. This is the highest death toll from fire in South Korea in almost a decade.

The fire is believed to have started at about 7:30 local time, according to fire chief Choi Man-woo. It originated on the ground floor in the emergency room as per various officials. The hospital has 98 beds and a medical staff of about 35, and specializes in long-term care of elderly patients. It adjoins a nursing home, all of whose 94 residents were evacuated. Staff carried some patients out of the hospital on their backs.

One patient, Jang Yeong-jae, who told his story to JoongAng Ilbo, said he escaped by removing a screen from a window to get to a ladder placed by firefighters. He described people “running around in panic, falling over and screaming as smoke filled the rooms”. The majority of the victims died from smoke inhalation and are believed to be elderly, said the head of the city’s public hospital, Chun Jae-kyung. A doctor, a nurse, and a nursing assistant have died, according to the fire service; it took three hours to put out the fire.

In a press briefing, Seok Gyeong-sik, the director of the hospital, apologized to patients and their families. Son Kyung-chul, its chairman, stated that there were no sprinklers because the facility was small. Sprinklers are being installed in the nursing home, where a new law requires them by June 30.

Last month, 29 people died in a fire in a gym in Jecheon; the owner and the manager were arrested for safety violations. In 2014, a blaze in a nursing home in Jangseong left 21 dead. The President of South Korea, Moon Jae-in, responded to the Friday fire by calling an emergency meeting of his staff, and promised that the cause would be found rapidly “to prevent the recurrence of the fire in the future”.
