Don Herbert, also known as television's science teacher Mr.Wizard, died at his home Tuesday of bone cancer. He was 89.

Mr. Wizard's target audience was kids (baby boomers: you may already know this) and his lessons taught youngsters to use the thinking skills of scientists through workshop experiments using simple household items. His 1950s series Watch Mr. Wizard was so good it won a Peabody Award in 1954, and Herbert was one of David Letterman' first guests when the show Late Night With David Letterman debuted in 1982. Herbert's show made it to Nickelodeon too and ran from 1983 to 1991. Reruns were shown until 2000. Nickelodeon's Mr. Wizard episodes are available here.

A native of Waconia, Minnesota, Herbert graduated from LaCrosse State Teachers College in 1940; served as a U.S. Army Air Corps pilot during World War II; and worked as an actor, model, and radio writer before reaching fame on Mr. Wizard in Chicago -- and then New York -- on NBC.

He is survived by six children and stepchildren and by his second wife, Norma.

There are sometimes silver linings to the darkest of cancer clouds. I know -- because I have the dark cloud of HER2 positive breast cancer hanging over my head. HER2 positive means the tumor removed from my breast was aggressive. It aggressively over-expressed a protein that accelerates tumor growth. And it led to a poor prognosis -- that might be considered a good one too.

You see, research on the whole HER2 issue is turning up some pretty powerful potions. Like Herceptin -- the drug that miraculously cuts recurrence upwards of 50 percent for positive women like me. I was a lucky recipient of this drug. And the pharmacist who mixed the drug for all 17 of my infusions tells me it's really a good thing I have this HER2 problem -- because the drugs created to attack the problem may just cure me of my disease.

So in an odd turnabout -- from bad luck to good fortune -- I am not so sad my tumor was aggressive. It means there are bonus treatments for me. And if my cancer comes back and Herceptin no longer works, there is another drug called Tykerb. And now the Army is leading its own breast cancer vaccination study. The focus -- HER2.

Early study results from Walter Reed Army Medical Center in Washington, D.C. suggest a 50 percent reduction in disease recurrence for HER2 positive women who receive a vaccination of AE37.

AE37 targets HER2 and boosts the body's immune system so it can battle the protein before it stimulates growth. It's similar to Herceptin, but the activity of AE37 stimulates a patient's own immune system to recognize the cancer target rather than interacting with the target directly.

Should the Food and Drug Administration decide to support this study, it will proceed to Phase 3 testing, which includes a much larger pool of participants.

U.S. Army Col. Dirk Spanton's back hurt and he felt tired, but then he was wearing a 40-pound flak vest and getting half the amount of sleep, 4 hours a night, most normally get to feel rested and ready to go the next morning. He felt healthy, bench-pressing 205 pounds in repetitions of 10 several times a week, and did not anticipate anything was seriously wrong, other than the physical wear and tear from the rigors of war.

Within days of returning home after three tours and 32 months in Iraq, Spanton fell ill and was taken to the hospital. It was then the back pain and fatigue were explained. He had cancer of the liver bile ducts, and the physicians suspect he had cancer for awhile. Initially, they told him he had two months to live.

Spanton says he feels lucky. "I could have gotten killed while I was over there and not gotten to say goodbye to my family. This way, I'm lucky. How many people get to say goodbye to their kids, their wife and their family? You don't like the short time frame, but it's at least a time frame."

He is currently undergoing chemotherapy. Although it is reported he is gaunt and has lost 40 pounds from the cancer treatments, they feel he might have a few extra months to live if the chemo can shrink the tumor.

Less than one year ago, Rep. John P. "Jack" Murtha, D-Pa., came crashing onto the national scene with his opinion that the U.S. military could accomplish nothing more in Iraq and should be pulled out of the war zone. It was a harsh opinion -- and one his Democratic partners thought might hurt their party at a time when they were trying to gain control of Congress. The fact that the Democrats had been seen as weak on national security didn't help. And then a funny thing happened.

Murtha, 74 -- a decorated Marine and the first combat veteran of the Vietnam War elected to the House of Representatives -- became one of the most popular Democrats around, despite or maybe because of his passionate beliefs. Once a behind-the-scenes kind of man, he is now in the public eye. He's out raising money for Democrats in many states. He's attending fundraising events with Al Gore and others. And he's gathering allies at every turn. And while he still faces opposition, he believes that he must make public what he stands for. And so he does. And because of his recent uncharacteristic charismatic presence, details about this once-to-himself man are emerging. Details like these: A local airport is named for him. An institute for the study of neuroscience and pain is named for him. And a breast cancer center bears the name of his wife, Joyce.

The Joyce Murtha Breast Care Center at Windber Medical Center opened its doors in February 2002. Located in Windber, Pennsylvania, this center began as a collaboration between Walter Reed Army Medical Center and Windber Medical Center and ever since its beginning has offered full diagnostic services for breast health and disease in one convenient location.

Murtha is surely raising awareness with his opinion about the military and national security and war. And even breast cancer gets a little press out of the whole frenzy surrounding this man and his efforts. Which reminds me that somehow, breast cancer seems to touch the lives of just about everyone is some way.

Radio Iowa reports that Lance Armstrong wants to fight the final battles against cancer by forming an army to wage war on cancer. Armstrong is in Iowa this week to participate in RAGBRAI, a cycling tour across the state of Iowa, and while there he is also giving interviews and making speeches about cancer and cancer survivorship.

"What we need is an army. We need an army of people. It starts in Iowa," Lance Armstrong said during an appearance in Newton on Wednesday. "Now's the time to make a difference and knock this thing out forever."

At the heart of the matter is federal funding for cancer research. For the first time in 35 years, the federal budget for cancer research has been cut -- which is essential to cancer research. Without federal funding, the advances made toward a cure for cancer are dramatically slowed. Armstrong is on a mission to ignite the political passions of the voters in this country to become an army against cancer.

"We hear every day how we're in the middle of a war, maybe a war in Iraq. It might be a war on terror. Let me tell you about a war. This is a war that's 35 years old and this is the war that's about time in my opinion that we get done with and that we finish," Armstrong said at a political event in Iowa City two days ago.
