Maybe getting schoolchildren to eat healthy foods isn't a hopeless struggle. Bucking some common notions, a University of Minnesota study has found that school lunch sales don't decline when healthier meals are served, and that more nutritious lunches don't necessarily cost schools more to produce.

"The conventional wisdom that you can't serve healthier meals because kids won't eat them is false," said Benjamin Senauer, one of three economists who wrote the study.

Previous studies have concluded that students prefer fatty foods and that healthier meals cost more to make, the authors noted.

The study, which appears in the December issue of the Review of Agricultural Economics, analyzed five years of data for 330 Minnesota public school districts. It looked at compliance with federal standards for calories, nutrients and fats.

When the researchers crunched all the numbers they found that schools serving the healthiest lunches did not see a falloff in demand.

While serving better meals does entail higher labor costs, the study found, that's offset by lower costs for more nutritious foods such as fruits and vegetables compared with processed foods. However, many districts need to upgrade their kitchens and train their staff to prepare these foods, the researchers said.

The study's conclusions rang true for Jean Ronnei, director of nutrition services for St. Paul Public Schools, which serves more than 46,000 meals daily. The district was held up by the authors as a model for others.

Jeff and Diana Kerr fell in love with the Guatemalan baby girl the moment they saw her photograph. The Minnesota couple decorated her pink and white nursery with pictures of flowers and butterflies, but now they don't know if the 8-month-old will ever become their daughter.

The Kerrs are among thousands of Americans trying to adopt 3,700 babies who are caught in limbo as Guatemala's lawmakers debate new rules that could all but shut down a largely unregulated system that has become the speediest place in the world to finalize an adoption.

"It's an emotionally taxing process," said Jeff Kerr, a 44-year-old financial adviser from Lino Lakes, Minn. "Every day you look at her picture and wonder if you're going to bring her home."

As early as this week, the legislature is expected to debate new rules to eliminate potential fraud in Guatemala's adoption process, which until now has been run from beginning to end by notaries who work with birth mothers, determine if babies were surrendered willingly, hire foster mothers and handle all the paperwork.

These notaries charge an average of $30,000 for children delivered in about nine months — record time for international adoptions. The process is so quick that one in every 100 Guatemalan children now grow up as an adopted American.

The small Central American country sent 4,135 children to the U.S. last year, making it the largest source of babies for American families after much-bigger China.

The adoptions are a $100 million a year industry for notaries.

Each holiday season, a couple hard-to-find toys send parents hunting from store to store. And, each season, they're soon forgotten: Has your Elmo gotten any tickles lately?

But this year, it looks like the gift everybody is looking for is the same as last year: the Nintendo Wii.

A year after its launch, the small video game console sells out almost immediately when it reaches stores, even after Nintendo Co. has ramped up production several times.

"Right now, if you work at it, it's not too hard," said John Lawrence, of Fort Worth, Texas, who bought a Wii a few weeks ago for his 9-year-old grandson. It took him some online sleuthing to find one at a local GameStop.

"People have not gotten into the Christmas shopping mode. Once people get into that mindset, this is going to be an impossibility as it was last year," Lawrence said.

With the Wii, Nintendo set out make a console that would entice people who were not hardcore gamers, and it has succeeded. Janet Presti stood an hour in line at the Nintendo World Store in New York on Tuesday last week to get a Wii for her three children, but it wasn't just for them.

"I played it at my sister's house and I loved it," she said. Her household already has three game consoles: an Microsoft Xbox 360, a Sony PlayStation 2 and a Nintendo GameCube.

The Wii responds to the user moving the wand-like wireless controller, while other consoles are controlled by a confusing array of buttons and joysticks. It also comes with an array of casual, nonviolent games that appeal to adults.

The more money a married woman earns, the less housework she will do regardless of how much her spouse earns, according to a new study.

A researcher at the University of Massachusetts Amherst found that big paychecks equal less cooking and cleaning in a study of 918 women in double-income families.

Married women who made $40,000 or more a year spent nearly one hour less on housework per day than women who earned $10,000 or less, according to the findings based on data from the National Survey of Families and Households.

"Up to this point, people have thought that the important thing was how much money a woman makes compared to her husband. But the only thing that matters is how much money she earns," Sanjiv Gupta, the study's author, said in an interview.

The study, which is published in the Journal of Marriage and Family, showed that for every $7,500 in annual income a married woman earned, she performed one hour less of housework each week.

A mutated version of a common cold virus has caused 10 deaths in the last 18 months, U.S. health officials said Thursday.

Adenoviruses usually cause respiratory infections that aren't considered lethal. But a new variant has caused at least 140 illnesses in New York, Oregon, Washington and Texas, according to a report issued Thursday by the U.S. Centers for Disease Control and Prevention.

The illness made headlines in Texas earlier this year, when a so-called boot camp flu sickened hundreds at Lackland Air Force Base in San Antonio. The most serious cases were blamed on the emerging virus and one 19-year-old trainee died.

"What really got people's attention is these are healthy young adults landing in the hospital and, in some cases, the ICU," said Dr. John Su, an infectious diseases investigator with the CDC.

There are more than 50 distinct types of adenoviruses tied to human illnesses. They are one cause of the common cold, and also trigger pneumonia and bronchitis. Severe illnesses are more likely in people with weaker immune systems.

Some adenoviruses have also been blamed for gastroenteritis, conjunctivitis and cystitis.

More than 1 million cases of chlamydia were reported in the United States last year - the most ever reported for a sexually transmitted disease, federal health officials said Tuesday.
"A new U.S. record," said Dr. John M. Douglas Jr. of the Centers for Disease Control and Prevention.

More bad news: Gonorrhea rates are jumping again after hitting a record low, and an increasing number of cases are caused by a "superbug" version resistant to common antibiotics, federal officials said Tuesday.

Syphilis is rising, too. The rate of congenital syphilis - which can deform or kill babies - rose for the first time in 15 years.

"Hopefully we will not see this turn into a trend," said Dr. Khalil Ghanem, an infectious diseases specialist at Johns Hopkins University's School of medicine.

The CDC releases a report each year on chlamydia, gonorrhea and syphilis, three diseases caused by sexually transmitted bacteria.

Chlamydia is the most common. Nearly 1,031,000 cases were reported last year, up from 976,000 the year before.

The count broke the single-year record for reported cases of a sexually transmitted disease, which was 1,013,436 cases of gonorrhea, set in 1978.

Putting those numbers into rates, there were about 349 cases of chlamydia per 100,000 people in 2006, up 5.6 percent from the 329 per 100,000 rate in 2005.

CDC officials say the chlamydia record may not be all bad news: They think the higher number is largely a result of better and more intensive screening.

Nike Inc is recalling 235,000 football helmet chin straps after receiving reports of head and face injuries because the straps broke, the

U.S. Consumer Product Safety Commission said on Tuesday.

The recalled football helmet chin strap was made in China and was sold at sporting good stores throughout the United States from April 2006 through October 2007, the safety agency said.

Consumers should stop using the chin strap immediately and contact Nike for a redeemable product voucher, it said.

Nike received 18 reports of the chin strap breaking and injuries that included two concussions, two facial cuts that required stitches and a broken nose, the safety agency said.

The chin strap consists of a plastic cup with a foam liner, straps and four metal snaps. The strap sold for about $20 and was offered in both youth and adult sizes.

The safety agency posted photographs of recalled chin strap and details on its Web site at http://www.cpsc.gov/cpscpub/prerel/prhtml08/08081.html.

Children and teenagers with attention deficit hyperactivity disorder have developmental delays of up to three years in some regions of the brain, U.S. researchers said on Monday.

"The sequence in which different parts of the brain matured in the kids with ADHD was exactly the same as in healthy kids. It's just that everything was delayed by a couple of years," said Dr. Philip Shaw National Institutes of Health's National Institute of Mental Health.

Shaw said the delays are most pronounced in regions of the brain that are important for controlling thought, attention and planning.

ADHD is a condition suffered by about 2 million U.S. children that often becomes apparent in preschool and early school years. Children with ADHD have a tougher time controlling their behavior and paying attention.

Shaw said the study helps settle the question of whether the brain develops differently in children with ADHD or is just delayed. "This is very much in favor of a delay," said Shaw, whose study appears in the Proceedings of the National Academy of Science.

The finding was based on imaging studies involving 223 children and teens with ADHD and 223 without the disorder.

Jesse Lackman says his son spends a dozen hours a week waging medieval combat across the dreary dreamscapes of computer games. Just don't expect to find Lackman sitting beside him battling ogres and dragons.

"It's just such a waste of time," said Lackman, 47, a power plant operator from Center, N.D. "I tell him, "Do something that has some lasting value.'"

Lackman's avoidance of the digital diversions that captivate his 15-year-old son, Tyrus, is shared by many parents. More than four in 10, or 43 percent, of those whose young children play video or computer games never play along with them, according to an Associated Press-AOL Games poll released Monday.

While experts debate whether electronic gaming is bad news or a blessing for children and their families, many parents are voicing their preference by never — or seldom — joining their kids when it's time to slay cyber scoundrels.

Besides those who simply don't play the games with their children, another 30 percent say they spend less than an hour a week doing so. All told, about three in four parents of young gamers never or hardly ever touch the stuff.

China-made toys seized in Hong Kong were being tested Thursday after scientists in Australia found that similar ones contained a chemical that converts into a powerful "date rape" drug when ingested, officials said.

At least five children - two in the United States and three in Australia - have been hospitalized after swallowing the toy beads, which are used in arts and crafts projects. They can be arranged into designs and fused when sprayed with water.

Australian scientists say a chemical coating on the beads, when ingested, metabolizes into the so-called "date-rape" drug gamma hydroxy butyrate. When eaten, the compound - made from common and easily available ingredients - can induce unconsciousness, seizures, drowsiness, coma and death.

The toys were sent to a laboratory in Hong Kong for tests, a customs official said, speaking on condition of anonymity because of policy. If the tests come back positive for the chemical, suppliers of the toy in Hong Kong could face a year in jail and fines of $12,877, she said.
