Blanchett turns her back on Hollywood for theatre

SYDNEY, Nov 10: Oscar-winning Australian actress Cate Blanchett said today she never planned to be a Hollywood movie star and is content to turn her back on tinseltown to pursue her first love, the theatre.

Blanchett, who along with her husband playwright Andrew Upton have been appointed creative directors of The Sydney Theatre Company (STC), says she will now only allow three months a year for filming.

''The acceptance of the role of co-creative director of this company is not a dalliance. It is an absolutely firm commitment,'' she told a news conference at the STC's Wharf Theatre on Sydney Harbour.

''Sometimes I may take that (three months) up, sometimes I may not but my primary responsibility is to co-manage and lead this company whilst also maintaining my own engagement as an artist.''

Now 37 and a mother of two, Blanchett says she is tired of being called a Hollywood celebrity.

''I'm not interested in that label for myself personally but obviously if there's some cache around fame its a by-product, and if that by-product can be harnessed for the company's benefit then fantastic,'' she said.

Blanchett began her acting career at the STC 13 years ago, when she first appeared in its production of ''Oleanna'', a year after graduating from acting school.

She made her film debut in ''Parklands'' in 1996 and in 2005, Blanchett won an Academy Award for best supporting actress in ''The Aviator'' alongside Leonardo DiCaprio.

Her latest film, ''Babel'', in which she stars with Brad Pitt, was released in the United States last month to acclaim and is being suggested as a possible Oscar nomination.

PUTTING ARTISTS FIRST

Blanchett said she never intended to become a movie star: in fact, film work was frowned upon at her acting school.

''It wasn't something I necessarily trained to do,'' she said, but conceded it was ''very, very important that actors get the opportunity to work in all mediums''.

This month, Blanchett will direct the STC's ''A Kind of Alaska'', marking her first project in the role.

Upton has also written several plays for the company, and was recently appointed as the company's artistic associate.

''We're extremely excited and honoured to be chosen ... And its possibly the most significant decision we've ever made apart from getting married,'' said Upton.

''This has always been a company that's put the artists first, actors want to work here. The plan therefore is to extend the reach, deepen the potency and continue the opportunities this company offers both to artists and audiences.''

Blanchett said she had not yet decided whether she would mainly perform, direct or write plays for the company.

''Andrew and I are not seeking to re-invent ourselves and as directors to the Sydney Theatre company we come first and foremost as an actor and as a writer,'' said Blanchett.

''If I am lucky enough to be offered a good role theatrically it would be obviously through and connected with the STC, but a good film role -- we all know how rare those things are -- then I'm willing to pursue it,'' she said.

Sea urchin gene map filled with surprises

WASHINGTON, Nov 10: Sea urchins may be blind, but they have the same genes that help people see, as well as genes for a sense of smell and one of the most complicated immune systems in the animal world, researchers reported today.

They also have genes associated with diseases such as Huntington's and muscular dystrophy, offering new routes to understanding illnesses, the researchers write in Friday's issue of the journal Science.

The sea urchin -- a pincushion-shaped animal found at the bottom of the sea and perhaps best known for its long, sharp spines -- shares more than 7,000 genes with humans, the international team of researchers found yesterday.

It was long known to be more closely related to humans and other vertebrates than other creatures favored by biologists for research, such as fruit flies and C elegans roundworms.

Comparing human genes to their counterparts in other species can help scientists figure out why they evolved, and find ways to help when things go wrong.

The series of studies published in Science confirm this relationship and also make some surprising findings, such as genes for sight found at the bottom of their feet.

''I've been looking at these organisms for 31 years and now I know they were looking back at me,'' said Gary Wessel, a biology professor at Brown University in Rhode Island who worked on one study.

''We've already learned an enormous amount from the sea urchin, from something as basic as how identical twins form to in vitro fertilization procedures,'' Wessel added in a statement.

''With a complete map of the urchin's DNA, we can now learn more quickly and easily how each process works during development,'' he said.

KELP-EATERS

The team of researchers, led by George Weinstock of Baylor College of Medicine, studied Strongylocentrotus purpuratus, commonly known as the California purple sea urchin. It eats kelp growing on the bottom of the Pacific.

They found that the urchin has about 979 genes for proteins that sense light and odors -- similar to what is found in vertebrates that actually do see and smell things. How the sea urchin uses them is not yet clear.

Also remarkable is the animal's immune system, said immunologist Jonathan Rast of the University of Toronto.

The immune system is one thing that differentiates one species from another -- humans have big differences from chimpanzees, for example -- and Rast hopes the sea urchin's immune system will help in understanding how the human immune system evolved.

Like people, sea urchins have many immune genes that are active in the gut, which may help in coping with symbiotic bacteria that help digest food.

''It is one thing to be able to recognize all bacteria and get rid of all of them. It is another thing to maintain that in a complex way that you don't kill all of them,'' Rast said in a telephone interview.

Vertebrates have adaptive immune systems as well as innate immune systems that attack invaders without necessarily recognizing them, but invertebrates do not.

Urchins appear to have the genetic predecessors to the adaptive immune system -- the antibodies and T-cells that can change and respond to new germs, the study showed.

''They are probably acting in a different way but it was a real surprise to find them,'' Rast said. ''If we can understand how they are acting in a sea urchin, it will help us understand how the system emerged in vertebrates.''

Chinese city encourages couples to go for second child

BEIJING, Nov 10 To offset the ageing population problem, couples in the booming southern Chinese metropolis of Guangzhou have been encouraged to go for a second child against the official one-child norm.

Guangzhou has taken the lead in urging couples who are the only children of their families to have a second child.

Parents who are the only children of their families are being "encouraged" to have a second child in a major effort to balance the city’s aging population, ‘China Daily’ reported.

"This is not a local policy, the encouragement we are giving conforms with the national family planning system," said Duan Jianhua, deputy director of the Population and Family Planning Committee in Guangzhou, capital of Guangdong Province.

According to a policy issued by the National Population and Family Planning Commission in 2000, couples from one-child families in 27 provinces are allowed to have a second child.

"The policy aims to help reduce the pressure on younger members of society caused by ever-increasing aging populations," Duan said.

The report comes a day after a senior Chinese official said that the nation’s ‘one child’ per couple family planning policy had prevented 400 million births and helped the world’s most populous nation to achieve faster socio-economic growth.

However, according to Duan, there are only a small number of couples in Guangzhou willing to have a second child, due to the increased financial burden.

At present, Guangzhou has more than a lakh married couples without children and 372,631 one-child families.

Meanwhile, the city’s municipal government is considering to provide financial aid to the hard-up only-child families. (PTI)

Japan orders broadcasts about N Korean abductees

TOKYO, Nov 10: Japan ordered national broadcaster NHK today to use overseas radio programmes to emphasise the issue of citizens abducted by North Korea years ago, an unprecedented move criticised by some as violating press freedom.

The abductees, snatched by North Korean agents in the 1970s and 1980s and taken to the reclusive state to help train spies, are a highly emotive issue for many Japanese, and Prime Minister Shinzo Abe initially won voter popularity by supporting their families.

North Korea admitted in 2002 to abducting 13 Japanese, and it sent five of them back and said the other eight were dead. But Japan has called for information about the eight reported dead and has said another three of its citizens were also abducted.

''We are making the move because we believe giving the abductees hope is very important,'' Chief Cabinet Secretary Yasuhisa Shiozaki told a news conference yesterday after a Government panel approved the broadcasting order.

Japanese law allows the Government to order NHK to broadcast certain themes overseas, but it had so far avoided specifying any particular subject matter.

The Mainichi Shimbun daily said in an editorial that the move threatened to open the way for more government meddling in the press.

''It would be difficult for NHK to criticise government policies it has been ordered to broadcast, preventing it from carrying out its responsibilities as a news organisation,'' it said on Thursday.

The idea surfaced earlier this year after news reports that shortwave radio broadcasts about the abductees by a private group were being jammed by North Korea.

NHK said in a statement this week that it would ''continue to make independent editing decisions and have news coverage that is accurate, fair and unbiased.''(AGENCIES)

Allergy to ladybugs seen in infested homes

NEW YORK Nov 10: The exotic ladybug species, Harmonia axyridis, could be a significant cause of respiratory allergy for residents of homes infested with these insects, clinicians from Kentucky warn.

This particular ladybug was first introduced from Asia in the 1970s and early 1980s in some eastern and southeastern states to control agricultural pests. Recent studies have reported that the H axyridis population is gradually increasing across the US and replacing the native species of ladybugs.

''Entomologists now report a rapid increase in ladybug numbers, giving rise to increasing complaints of residential infestations,'' Dr Kusum Sharma and colleagues from the University of Louisville note in their report in the Annals of Allergy, Asthma and Immunology.

Until 2005, there were just nine cases of ladybug (H axyridis) hypersensitivity reported in the literature. However, in an anonymous survey of 99 residents of H. Axyridis-infested Kentucky homes, Dr. Sharma's team found the prevalence of self-reported ladybug hypersensitivity -- defined as worsening of allergy symptoms when ladybugs infested the home -- to be as high as 50 per cent.

Nineteen per cent of respondents reported allergy symptoms on direct contact with ladybugs and 31 per cent reported the use of extra allergy medications during times of infestation.

''The correlation between worsening of allergy symptoms and time of infestation was significant for spring, fall, and winter infestations,'' Dr Sharma noted in comments to Reuters Health.

''We believe that this study will have significant clinical implications,'' the researcher continued. ''Many cases of ladybug hypersensitivity go undiagnosed in the absence of proper recognition. We hope that patients with spring, fall and winter allergies will now be asked about ladybug infestation.''

However, even when ladybug hypersensitivity is suspected, currently there is no commercially available ladybug extract to aid diagnosis. ''Hopefully, we will soon see reagents for diagnostic testing on the market,'' Dr. Sharma said.

''This study shows that the prevalence of ladybug hypersensitivity is significant enough to warrant more research in this area,'' Dr. Sharma added.

Lifestyle changes shown to cut risk of diabetes

LONDON, Nov 10: Losing weight, cutting down on saturated fats, eating more fibre and exercising 30 minutes a day can make a difference when it comes to diabetes.

Finnish researchers have shown that lifestyle changes not only reduce the odds of high-risk people developing type two diabetes but can also postpone the onset of the illness.

''From a public health point of view there is an important message: an intensive lifestyle intervention lasting for a limited time can yield long-term benefits in reducing the risk of type two diabetes,'' said Jaakko Tuomilehto of the National Public Health Institute in Helsinki.

About 194 million people worldwide suffer from diabetes and public health experts predict the number could reach more than 300 million by 2025. Most cases are type 2 diabetes, which is caused by an inability to regulate glucose (sugar) in the body properly, and linked to being overweight and obese.

Diabetes also raises risk of heart disease, stroke, blindness and kidney damage, so preventing or delaying the illness can have huge health benefits.

''Lifestyle intervention works very well,'' Tuomilehto told Reuters.

People with impaired glucose tolerance (IGT) have a higher chance of suffering from diabetes. About 50 per cent will develop diabetes during the next 10 years if nothing is done, according the researchers who reported their findings in The Lancet medical journal.

Tuomilehto and his colleagues compared the effects of lifestyle changes on more than 500 men and women in Finland with IGT. Half were given intensive diet and exercise counselling while the other half acted as a control group.

During a seven-year follow up of the patients, the scientists found a significant difference between the two groups. There was about a 15-20 per cent reduction in diabetes risk in the intervention group.

''Although a lifestyle intervention alone, even if successful, does not necessarily prevent type two diabetes in all individuals, it will still postpone the onset of the disease,'' Tuomilehto added.

Diabetes UK said the study confirms the importance of lifestyle changes in reversing the type two diabetes epidemic.

''It clearly shows the prolonged benefits that physical activity and an improved diet can bring, especially to those most at risk,'' said the charity's Jemma Edwards.

UK jails Internet predator who targeted teen girls

LONDON, Nov 10: A British court jailed a man who has wrested control of the computers of girls as young as 13 in order to blackmail them for his sexual gratification.

The Inner London Crown Court sentenced 36-year-old Adrian Ringland from the northern English town of Ilkeston to ten years in prison after he pleaded guilty to blackmail, indecency with a child and grooming, a term used to describe methods paedophiles use to befriend their victims.

Ringland would pretend to be a teenage boy in Internet chat rooms in order to lure young girls into conversation, said Jenny Hopkins of the Crown Prosecution Service.

Then he would raid their computers for embarrassing material he could use to blackmail them into posing for indecent photos.

''Even after he had been arrested and placed on bail for his initial internet offences he continued to groom a 13-year-old girl and then formed a sexual relationship with her,'' Hopkins told BBC television.

Ringland would send the girls a dummy photo of his teenage persona containing a hidden computer virus -- known as a Trojan Horse -- which allowed him to gain control of their computers.

He would then find potentially embarrassing material on the computers which he threatened to disclose to the girls' parents or friends if they refused to pose for explicit photos.

''To demonstrate the control he had over them, he would turn their monitors on and off, or he would switch their printers on and off. These girls were terrified,'' Hopkins said.

Ringland was tracked down and arrested yesterday after a victim in Canada plucked up the courage to report what had happened.

He pleaded guilty to one count of indecency with a child, three counts of blackmail and six counts of making indecent photos of children.

He also pleaded guilty to one offence of grooming and six offences of sexual activity with a girl aged between 13 and 15.

His victims, girls aged between 13 and 16, lived in Britain and Canada.

Britain's spy chief warns of terrorist plots

LONDON, Nov 10: Britain's intelligence agency head was quoted today as saying up to about 30 major terrorist plots were being planned in the country and that

future threats could involve chemicals and nuclear technology.

Eliza Manningham-Buller, director general of MI5, said young British Muslims were being groomed to become suicide bombers and that her agents were tracking some 1,600 suspects, most of whom were British-born and linked to al Qaeda.

''We are aware of numerous plots to kill people and damage our economy. What do I mean by numerous? Five? Ten? No, nearer 30 ... That we know of,'' Manningham-Buller said in a speech in London yesterday that was reported by British media.

Manningham-Buller, who said her warnings were not intended to alarm but to paint a frank picture of the reality, was quoted as saying the plots were ''priority one'' cases.

Last year, Britain suffered its worst peace-time attack when four British Muslims blew themselves up on London's transport network, killing 52 commuters and wounding hundreds.

''My officers and the police are working to contend with some 200 groupings or networks, totalling over 1,600 identified individuals who are actively engaged in plotting or facilitating terrorist acts here and overseas,'' she said.

Manningham-Buller said the number of cases being pursued by security services had risen by 80 per cent since January.

''Today we see the use of home-made improvised explosive devices. Tomorrow's threat may -- and I suggest will -- include the use of chemicals, bacteriological agents, radioactive materials and even nuclear technology,'' she said.

Extracts of her speech were carried by the BBC and several newspapers.

Manningham-Buller said it was clear from so-called ''martrydom'' videos that suicide bombers were motivated in part by ''their interpretation as anti-Muslim of UK foreign policy, in particular the UK's involvement in Iraq and Afghanistan''.

A growing number of people were moving ''from passive sympathy towards active terrorism'' through being radicalised or indoctrinated by friends, families or organised training events in Britain and abroad, said Manningham-Buller.

She said television and Internet chatrooms had helped to attract greater numbers.

''Chillingly, we see the results -- young teenagers groomed to be suicide bombers,'' she said.

WHO members elect bird flu expert Chan as chief

GENEVA, Nov 10: The World Health Organisation's (WHO) 193 member countries elected bird flu expert Margaret Chan of China to lead the United Nations agency tasked with preventing and fighting global health threats.

Chan, 59, was nominated on Wednesday by the WHO's executive board to succeed the late Lee Jong-wook as director general. The former Hong Kong health chief overcame contenders from Mexico, Japan, Spain and Kuwait for the top job in international health.

As the first Chinese national to head a major UN agency, Chan's election yesterday was seen by diplomats as a sign that China, a permanent member of the UN Security Council, was interested in playing a wider international role.

The profile of the WHO, which has a two-year budget of 3.3 billion dollars, has risen dramatically with the spread of AIDS and other diseases, and the emergence of new threats from the respiratory illness SARS and bird flu.

Chan, most recently the WHO's assistant director-general for communicable diseases, won praise as Hong Kong's health chief for helping douse an earlier bird flu outbreak by ordering the culling of some 1.5 million birds. She also battled SARS, which spread from Asia to other parts of the world in 2002 and 2003.

As head of the WHO, a position she can hold for two five-year terms starting in January, Chan will be responsible for staving off a feared bird flu pandemic, fighting chronic and infectious diseases, and improving poor-country health systems.

Her term will run from January 4, 2007 until June 30, 2012. (AGENCIES)

Annan hails panel report on revamping world body

UNITED NATIONS, Nov 10: United Nations Secretary-General Kofi Annan has welcomed a high-level coherence panel’s report on revamping the organisation’s development, humanitarian and environment portfolio, calling it ambitious yet realistic.

"We all now have a solemn obligation to seize the opportunity the panel has offered, and to take its recommendations forward with the same energy and sense of urgency that its members devoted to formulate them," Mr Annan said, after receiving the High-level Panel on UN System-wide Coherence in the Areas of Development, Humanitarian

Assistance, and the Environment report from panel co-chairs, the Prime Ministers of Norway and Pakistan.

"The changes proposed will enable the UN to respond better to new challenges, and support countries more effectively in their efforts to achieve development goals," he told an informal meeting of the General Assembly yesterday.

"I sincerely hope that together we will be able to carry out their recommendations, and thus make the UN system stronger, more coherent and responsive to the needs of people everywhere."

The report, titled Delivering as One, recommended a country-level consolidation of UN agencies, the strengthening of leadership on humanitarian and environmental activities, and the creation of both a new funding system and new women’s organisation.

The panel, led jointly by Prime Ministers Lumsa Dias Diogo, Mozambique, Jens Stoltenberg, Norway, and Shaukat Aziz, Pakistan, released the report, which global leaders requested at the 2005 World Summit in New York to lay the groundwork for a fundamental restructuring of UN work in the field.

"No one facing today’s challenges would design the UN system as it currently stands. To leave it the way it is would mean giving in to short-term national and institutional interests," said Mr Stoltenberg.

The report stated that currently the UN’s work on development is fragmented, weak and not properly structured to meet country needs, with more than one-third of UN Country Teams have ten or more agencies on the ground, and several with more than 20, resulting in ‘incoherent’ programme interventions and ‘excessive’ administrative costs.

"We have proposed a bold but realistic agenda for action," Mr Aziz said.

"It should ensure that the UN is well funded, and can respond more effectively to the needs of countries and communities everywhere."

Among recommendations was establishing "One UN" Country Programmes, which would streamline UN agency activities and be led by resident coordinator and handled by a strategic Sustainable Development Board that would eventually bring together boards of the UN Development Programme (UNDP), the UN Population Fund (UNFPA) and the UN Children’s Fund (UNICEF). The UNDP administrator would serve as a UN Development Coordinator, reporting to the Sustainable Development Board, the report suggested.

The panel also suggested testing the "One UN" programme in half- adozen countries next year to pave the way to a possible system-wide overhaul.

"We want the UN to be a strategic player at the country level, supporting us in the preparation and implementation of our nationally-owned development strategies," Mr Diogo said. (UNI)

Perrigo recalls 11 million bottles of pain killer

NEW YORK, Nov 10: Generic drugmaker Perrigo Co is recalling 11 million bottles of over-the-counter pain killer acetaminophen caplets after finding metal fragments in some batches, US health officials said.

The 500-milligram pills sold as store brands may have been sent to dozens of outlets around the United States, including including some owned by Wal-Mart, Safeway, CVS and Food Lion, the US Food and Drug Administration (FDA) said yesterday.

No injuries or illnesses have been linked to the products, the manufacturer and the FDA said.

Shares of Perrigo, the world’s largest manufacturer of store-brand pharmaceutical and nutritional products, fell 5.6 per cent to close at 17 dollars on Nasdaq.

The FDA said in a statement that it believed that based on available information the probability of serious adverse health consequences was remote.

"However, if a consumer were to swallow an affected caplet, it could result in minor stomach discomfort and/or possible cuts to the mouth or throat," the FDA said.

Acetaminophen is the active ingredient in Johnson & Johnson’s Tylenol but also is sold generically by various manufacturers. Tylenol is not subject to the recall.

Consumers should not take the recalled caplets and should consult a doctor if they think they may have been harmed, the FDA said.

Perrigo said it found one in 400,000 caplets may have contained metal traces.

FDA officials could not say if the caplets had been distributed nationwide or were concentrated in some regions.

The agency urged consumers to check its Web site for a list of stores that Perrigo supplied. It also provided numbers for each of the recalled 383 batches and said consumers could check the product label for a matching number.

The stores can be found at

www.Fda.Gov/oc/po/firmrecalls/perrigo/perrigocustlist.Html <http://www.Fda.Gov/oc/po/firmrecalls/perrigo/perrigocustlist.Html>, while the batch numbers are online at

www.Fda.Gov/oc/po/firmrecalls/perrigo/perrigobatchlist.Html <http://www.Fda.Gov/oc/po/firmrecalls/perrigo/perrigobatchlist.Html>.

CVS Corp said it would stop selling certain size packages of its CVS brand acetaminophen 500-milligram caplets until further notice.

Agency officials said they and Perrigo were investigating the source of the metal and had no reason to suspect the caplets had been intentionally contaminated.

Perrigo said it had traced the source of metal fragments to a third-party supplier, which it did not name.

Some of the caplets were made as long as three years ago with expiration dates ranging from September 2006 to August 2009, FDA officials said.

Perrigo discovered the problem after finding some manufacturing equipment was wearing down prematurely, the FDA said. The company passed 70 million caplets through a metal detector and found about 200 contained metal fragments ranging in size from "microdots" to "portions of wire 8 millimeters in length," the FDA added.

Most metal fragments were the size of two grains of salt, Perrigo said.

The company said it was is in possession of 100 per cent of the batch that originally prompted the investigation.

Perrigo told the FDA about the finding on november one, said Fred Richman, head of compliance management and operations in a division of the FDA’s regulatory affairs office. Perrigo said it informed the agency on November second.

Perrigo, based in Allegan, Michigan, said the recall was expected to cost 2.9 million dollars.

Its fiscal first-quarter results will now include an after-tax charge of 667,000 dollars, or one cent a share, because of the recall, reducing its quarterly earnings to 18 cents a share, Perrigo said. It also reaffirmed its earnings outlook.

The company has in the past recalled other products containing acetaminophen, including a children’s liquid pain reliever in 2005 because of an unmarked dosing syringe.

In 1999, Perrigo recalled 44,736 bottles of 500-milligram acetaminophen pills from dozens of stores because of mold.(AGENCIES)

Modified virus kills brain cancer in mice

NEW YORK, Nov 10: An engineered form of a virus can infect and kill malignant glioma cells while leaving normal cells unharmed, according to new research findings.

In its natural form, vesicular stomatitis virus (VSV) is a potent cancer-killer in a number of tumor cell types, including brain tumors called gliomas, but it can be lethal. "We engineered VSV to make it safer," Dr Peter A Forsyth, of the Clark Smith Integrative Brain Center at the University of Calgary, Canada, noted in comments to Reuters Health.

The researchers evaluated the susceptibility of 14 malignant glioma cell lines to infection and killing by the modified VSV. It infected and killed all 14 cell lines but had no effect in normal cell lines, the team reports in the Journal of the National Cancer Institute.

In mice carrying human malignant glioma, the tumor regressed markedly after it was injected with modified VSV. When the agent was given intravenously, mice treated with live mutant VSV survived significantly longer than those injected with dead virus.

This means, Forsyth pointed out, that mutant VSV "can be given intravenously rather than injected directly into the brain, so it’s easier for patients than an operation and if needed it can be given several times as an outpatient."

Modified VSV "is promising in mice and we are excited about it," he told Reuters Health, "but we need to be cautious and continue to evaluate it before moving into a clinical trial." (AGENCIES)
