Researchers at U.C. Davis are trying to connect the dots leading to 10 autism clusters in California. One theory is that those parents are using certain hazardous household products, exposing their kids to dangers linked to the neuro-developmental disorder that usually surfaces by the time a child turns three.

According to the Contra Costa Times and other news sources reporting the findings, the study authors don’t attribute the cases to a toxic waste plant or other widespread polluter, but rather to household items like cleaners or landscaping products.

The report released by the University this week says the clusters show autism rates nearly twice the amount of ones in surrounding areas, including three in the Bay Area: Parts of Redwood City, San Carlos and Belmong; Parts of Santa Clara and Sunnyvale; Western San Francisco. No clusters were found in the East Bay.

Other clusters are in Southern California and the Central Valley. And one San Diego cluster was found to have rates of 61.2 per 10,000 births, compared with 27.1 per 10,000 births in the surrounding region. The researchers said the study is the first one looking at the geography of autism births in the state to learn of local sections of elevated environmental risk.

In producing the study, which was published online in the journal Autism Research, the scientists looked at nearly all of the 2.5 million births recorded in California from 1996 to 2000. The report says some 10,000 children born during that period were later diagnosed with autism.

The scientists who conducted the study are now conducting two additional studies examining the environmental causes of autism, and plan to collect dust samples from the homes of 1,300 families to see if common chemicals are the culprits.

It may have been published a couple of years ago, but Americans are now catching up to the message of Steve and Annette Economides and are eagerly plunking down their pennies for the hot home economics crash course.

The authors of America’s Cheapest Family have done remarkably well feeding their family of seven on just $350 per month, paying off their first house in nine years and purchasing a second, larger home, buying cars with cash, taking nice vacations, and yes, even socking away money in savings.

They’ve done so well, they are hitting the television news circuit including Inside Edition and receiving praised on numerous green websites to teach a fairly clueless nation the ABC’s of creating a comfortable, debt-free life. Forget the Joneses! It’s time to keep up with the Economides.

The couple, who live in Scottsdale, Arizona (a money-driven, rapidly built-up, energy-sucking environ), launched their popular bimonthly newsletter, The Home Economiser, in 2003 and have appeared in Good Housekeeping as well as on National Public Radio and Good Morning America.

Perhaps their message has been somewhat lost until the proverbial s–t hit the fan, sending many of us seeking advice from the successfully frugal among us, the ones who arrogantly yet wisely uttered I told you so as we maxed out our credit cards.

According to publishers marketing this new debtors’ bible:

“You don’t need to be a CPA or a math wizard to learn their revolutionary system, which will teach you:

- hundreds of ways to save money on everyday household expenses, including groceries, clothing, and health care
- how to save in advance for major purchases such as homes, cars, and vacations
- how to stop living paycheck to paycheck
- how to eliminate debt . . . forever!”

Oooh, that sounds good, real good to the masses choosing between lesser evils of selling their homes, getting night jobs that will take them away from their kids, and selling what they can from cars to gold and furniture – anything to stay afloat.

While the Economides’ disciplined road to penny pinching offers a way to avoid those evils, Nature Moms points out some of the methods may not sit well with the green among us, namely buying processed foods in bulk while forgoing more costly fresh fruits and veggies for the last two weeks of the month.

” I think families that eat lots of fresh, raw, whole foods would have a lot of adapting to do but the basic plan is a good one,” says the author of the site. “I would probably feel more comfortable doing bi-monthly shopping expeditions with weekly trips to farmers’ markets for fruits and veggies.”

One of the best chapters deals with clothes shopping and how buying stylish second-hand finds can help you stay within your budget and then some. And in terms of housing costs, they advise paying off your mortgage in less than 10 years.

For some of us the lessons have come a bit late, but not too late to try a new tack.
