Those venturing into space face a very serious occupational hazard -- cancer. The disease can be caused by radiation from the cosmic rays and solar flares astronauts encounter when they travel beyond the Earth's protective magnetic layer or magnetosphere.

British scientists are working on rectifying this problem by creating a Star Trek-style deflector shield to protect astronauts from radiation.

Think about this:

Scientists wish to mimic the magnetic field that protects the Earth with shields deployed around spacecraft and on the surfaces of planets to deflect harmful energetic particles.

Details, presented at the Royal Astronomical Society's National Astronomy Meeting in Preston, UK, include the following:

• The idea has been linked to the deflector shields that protect the USS Enterprise and other spacecraft on Star Trek. The shields, like on the TV show, could be switched on and off.

• In order to make the shield, scientists must generate a magnetic field and then fill it with ionized gas, or plasma. As energetic particles interact with the plasma, energy is sapped away from them, causing them to slow down.

• Protective shelters would not work on long-duration space journeys due to the drip of energized particles, thought to be as harmful as large solar storms.

"The nice thing is that magnet technology is really quite evolved here on Earth," says Dr. Mike Hapgood, from the Didcot-based research centre. The question is can you take it into space?"

A team from Rutherford-Appleton plans to build an artificial magnetosphere in the laboratory. They would eventually like to fly a test satellite which would test the technology in space.

There's a bit of breast cancer news in just about every magazine out there -- news about treatments and protocols and studies, news about celebrity diagnoses, news about lives lost to breast cancer and lives conquering breast cancer, news that is scattered here and there and everywhere. But now, there is a magazine all about breast cancer -- and just about breast cancer. All sorts of breast cancer wisdom is conveniently packaged into one slick, glossy publication that debuted on newsstands yesterday, September 19.

Beyond: Live & Thrive After Breast Cancer is a semi-annual publication from Meredith Special Interest Media, part of the Meredith Corporation -- a leading media and marketing company and home to magazines such as Better Homes and Gardens, Ladies' Home Journal, Parents, and Fitness. Meredith's new breast cancer venture provides women living with the disease -- and those who may one day encounter it -- with support and with the latest information on treatment and recovery.

The Fall/Winter 2006 premiere issue of Beyond features a cover story about Dallas Mayor Laura Miller, a survivor forging ahead into a life beyond breast cancer. Also filling the pages are inspiring real-life profiles and stories, nutritional advice, up-do-date medical information, fashion tips, the Pink Pages -- a resource guide that details upcoming races and products that support breast cancer -- and much more.

Behind the scenes of this issue is an advisory board of leading experts in the breast cancer field. Experts include Susan Brown, the health manager at Susan G. Komen Foundation; Carolyn M. Kaelin, director of Comprehensive Breast Health Center and breast cancer survivor; and Lillie Shockney, Administrative Director at Johns Hopkins Breast Cancer.

If there is one theme common to women surviving breast cancer, it must be the desire to live beyond the control of this life-threatening and life-changing illness, to recapture an existence that resembles something normal, to embark on a journey outside the confines of cancer. Tips, techniques, strategies, and inspiration for accomplishing these feats are printed on the pages of this new magazine that is sure to reach its intended audience -- that today includes two million women who are living with breast cancer.

Where does the time go? Even though most of us have been experiencing the height of the summer season in the form of a nationwide scorcher of a heat wave, summer is almost over for school kids and teens leaving for college. Yes, in less than a month, it's back to school. There are advertisements everywhere you look for new school supplies and new school clothes. In preparation for the new school season, Duke Health has published Back to School Tips for Healthy Eating.

The experts say it is not about counting fat grams and calories but portion control and choices. According to pediatrician Dr. Terrill Bravender, "You don't have to be obsessive about it. If you generally eat healthy, there is room for some foods that aren't as healthy."

Dr. Bravender offers these basic common sense tips:

• Involve kids in lunchbox planning. If you let them make some choices about what goes into their lunchbox, they are more likely to eat it.
• Avoid the peanut butter and jelly rut. Nothing wrong with the traditional, but try new foods. Make it a food adventure.
• While everyone is still on summer break, encourage children to prepare their own lunch. Dr. Bravender suggests easy-to-make ideas like graham crackers with peanut butter and a glass of milk; fresh fruit with cheese cubes; a hard boiled egg with whole grain crackers; yogurt with a sliced banana; granola bars with milk; or tortilla chips and bean dip made without hydrogenated oils.
  

Ultimately, as the mother, what foods come in to the home are my choosing, so I try to make nutritious choices in food purchases. But I have found great success over the years by taking my kids to the grocery store with me, and allowing them to choose between several choices I offer. We also take a look at new foods, and talk about the food item. We read ingredients. Some we decide, by group vote, to bring home and try. During the growing seasons, they are with me when I stop at a roadside stand to buy local produce straight from the field, and each year we have an annual tradition of blueberry picking enough blueberries to last most of the year ahead. Food can be fun, and learning about good food a lifetime benefit in cancer prevention.

Death. We all have to face it yet for many it is an uncomfortable subject to think about much less talk about. Why do we have such a hard time facing it, fearing it, struggling with it? It is an ending here on earth and no one likes endings.

One of my all-time favorite actresses Sally Field, is taking a lead role in a film that is a bittersweet comedy about four adult siblings who gather at their dying mother's house in North Carolina for what they expect to be a quick, last goodbye. Instead, they find themselves trapped -- together -- for two weeks. Hence the title Two Weeks. It is a movie with a tough subject matter -- living with dying. In the movie Sally Field is playing a woman dying of cancer and only has four more days to live. She ends up living a lot longer.

''It's a human comedy. About the truth of what happens when you deal with this at home. A lot is very funny and a lot is very sad,'' director and writer Steve Stockman said.

Sally Field in no stranger to acting roles facing death with her characters in Forest Gump and Steel Magnolias. I for one can't wait to see this film that is full of great actors like Ben Chaplin, Tom Cavanagh, Julianne Nicholson, Glenn Howerton and Clea Duvall. The film is being shot entirely in Nashville. I hope to see another Oscar in the hands of Sally Field. Yes, we love you Sally.
