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.

In celebration of his 50th birthday, fitness enthusiast Patrick Thompson and his over-sized inflatable penguin Percy start the epic journey to cycle across Australia to raise funds for child cancer research today.

His fundraiser was inspired by the loss of three friends to cancer. Thompson estimates it will take 80 days to finish the journey from Margaret River in WA to the Manning River at Taree in NSW. He hopes to raise more than $50,000 for the Children's Leukemia and Cancer Research Foundation.

According to if it's bloody easy, everybody would be doing it Thompson, he has been training most of his life for this unusual and challenging event. The Pedalling Penguin Appeal website has been launched where you can learn more about Thompson, Percy the Penguin, check his progress at Where is Patrick? and donate a few dollars to a worthy cause.

Lori Raimondo set off on a cross country journey in May with the goal of raising $9,490 -- one dollar for every day that her mother battled breast cancer. And just yesterday, she reported that her trek is over, that she is back home in New York City after her amazing adventure in search of hope. I think she found the hope she was looking for because she not only met her goal -- she exceeded it. She raised a grand total of $12,610.90 while traveling 10,334 miles -- and every cent was donated to the Breast Cancer Research Foundation where hope for a cure just got a bit sweeter.

Lori coined her trip the Road for a Cure and what a road it was. She crossed many state borders, met charming and kind and outrageous locals, visited with friends along the way, ate at tucked-away restaurants and slept in quaint places, toured roadside stops, and while accompishing her fundraising chronicled it all through words and photographs that appear on her own personal blog. It's inspiring -- that Lori would give of her time and effort and spirit to help others. All in honor of her mother, who lost her battle with breast cancer, and in support of those currently fighting their own battles. I am truly thankful -- as a breast cancer survivor -- that the research that might one day save my life may be a result of Lori's courage and bravery and hard work and generosity.

Welcome home, Lori. And congratulations on a road well traveled.
