An Oxford skin cancer expert is weighing in on the recent advice that we would all be wise to sport our denim, polyester, and wool when we head into the sun's harmful rays.

It's an extreme approach, says dermatologist Dr. Robert Turner who believes this skin cancer prevention guidance could push sun seekers to do just the opposite.

Think about this:

"I just don't think this is practical," says Dr. Turner. "People will think it's ridiculous and just go out anyway. If you advise people to do something that is extreme, they're more likely to go the other way completely."

Dr. Turner agrees that clothing is better protection than sunscreen -- especially for children -- but he thinks expecting people to take such drastic cover is unrealistic. He'd much rather urge people to stay out of the sun completely during the middle of the day, when the sun's rays are scorching hot.

In a radical new approach to attacking cancer, researchers will soon attempt to kill tumors by infecting them with viruses that cause ailments like the common cold.

This virus therapy treatment -- considered the third pillar alongside chemotherapy and radiation -- could one day become standard battle against cancer.

One Belfast doctor says anything that could improve the lives of cancer patients is worth a try. And try is exactly what Leonard Seymour, Professor of Gene Therapy at Oxford University, plans to do when he begins leading trials later this year.

Seymour, who has been working with viruses that kill cancer cells while sparing healthy tissue, will use a stealth virus masked from the body's immune system with a polymer coat that could travel through the bloodstream and reach tumors.

Two viruses are likely candidates for study in the first clinical trials -- adenovirus, cause of a cold-like virus, and vaccinia, cause of cowpox and a component in the smallpox vaccine.

Preliminary research on mice shows that virus therapy works well on tumors resistant to standard cancer drugs. But several years of trials will be necessary before the therapy can be considered for use on all cancers.

Cancer ... it's kind of a big deal. That is the tagline for the Cross Country for Cancer blog. In a benefit to raise awareness and funds for cancer research at the Sidney Kimmel Comprehensive Cancer Center of Johns Hopkins University and for the American Cancer Society, six international college students are spending 45 days of summer cycling across America. The Cross Country for Cancer cycling team, who began their 4,000 mile journey in San Francisco, California, 13 days ago, plan to finish in Baltimore, Maryland.

Cross Country for Cancer is blogging the daily challenges and adventures of the cycling journey across America where this group of college students -- John Lian of Amherst; Ezra Pierce of Oxford; Jacob Pierce of UC Santa Barbara; Patrick Garfjeld Roberts of Oxford; Max Capener of Oxford; and David Lauterbach of Wheaton -- basically came up with a big idea and without any self-admittedly realistic sense of what is possible, simply agreed to go for it.
