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.

Fred Thompson, actor and former United States Senator from Tennessee, made the announcement today that he was diagnosed with lymphoma a few years ago and now is in remission.

Thompson added to that announcement that he was considering running in the 2008 Presidential Election. He stated today on Fox News, "I have had no illness from it, or even any symptoms. I am in remission, and it is very treatable with drugs if treatment is needed in the future -- and with no debilitating side effects".

You can find Thompson playing a district attorney Arthur Branch on the NBC drama Law and Order.

Former NASCAR champion Benny Parsons, hospitalized on December 26 due to complications from lung cancer, died today in Charlotte, North Carolina after a short battle with the disease. He was 65.

Parsons, who had not smoked since 1978, was diagnosed with cancer in his left lung in July 2006. He underwent aggressive chemotherapy and radiation and announced in October that he was in remission. But the intensive treatment rendered his left lung useless and then a blood clot appeared in his right lung, prompting his admission to the hospital where he spent his remaining days in an induced coma.

Parsons was confident he could survive with one lung and compared his condition to that of John Wayne.

"John Wayne lived and had a great career with one lung," he said. "There is no reason why I can't do the same. It will take a little while for the right lung to pull the weight for the left lung so until then I will still need to use oxygen when I walk. I won't need it sitting or commentating races and to me that is the main thing. If given a choice between cancer or losing a lung I would say that I got the right end of the deal."

Parson's intense spirit was his trademark. It motivated him to rise from a poor childhood, leave behind a taxi driving job, and head straight to the top of NASCAR. His success is marked by his 1994 induction into the International Motorsports Hall of Fame and his 1995 induction into the National Motorsports Press Association's Stock Car Racing Hall of Fame.

One of NASCAR's 50 greatest drivers and the 1973 champion, Parsons retired from racing in 1988 and headed straight into a broadcasting career. He spent the past six years as a commentator for NBC and TNT and even continued to call races from the booth during his treatment. He hosted a weekly radio program and kept fans updated on his condition on his very own blog.

Judging by the comments left for Parsons on a January 8th post about his hospitalization, there was an abundance of love for this man, nicknamed BP by the NASCAR community.

"He was a great driver and a terrific broadcaster, but above anything else he was a kind and generous human being," said Dick Ebersol, chairman of NBC Sports. "His character and spirit will define how he is remembered by all of us. Benny will be sorely missed."

Parson's death comes eight days after the death of NASCAR driver and Truck Series Champion Bobby Hamilton.

Diane Lane, award-winning actress, appeared on NBC's Today Show this morning and had her hair cut off on live television in the official launch of the Pantene Beautiful Lengths campaign. At the same time, 50 women volunteers across the country are having eight inches of their hair cut in a hair donation that will go to making no-cost wigs for women who have lost their hair during chemotherapy cancer treatment.

The campaign is hoping to inspire women and men to make a gift of their healthy hair, cutting it to create wigs for women in need. In addition, Pantene will launch the program with a $1 million donation to the Women's Cancer Research Fund for cancer research.

"This simple act of cutting my hair is going to make a profound difference to a woman who is fighting to regain both her health and sense of self," Lane said. "My dream is that every woman who hears about Pantene Beautiful Lengths will become inspired to grow her hair and donate a natural resource that only she can give." You can watch pre-show outtakes of the broadcast, as well as the Hope Pass it On video at Pantene Beautiful Lengths website. For those that missed the early morning show, NBC has not posted any video coverage of Lane's appearance. Not yet anyway, I checked.

In woman with fake boobs has real health worries, Busty and bothered wrote to women's medical health expert Dr. Judith Reichman asking if her breast implants will rupture during a mammogram or if there is a possibility that the implants will obscure signs of breast cancer. Dr. Reichman, who is NBC Today show's medical contributor on women's health, responded that both are valid concerns for the over four million women who have had breast augmentation. According the doctor, there were only 41 cases of implant ruptures during mammography reported to the U.S. Food and Drug Administration between June 1992 and October 2002.

As to breast implants obscuring mammography readings, implants can cause a 15 to 50 percent decrease in the mammographically visualized breast tissue and several studies have reported false negative mammograms -- those that missed the cancer -- in 12 to 67 percent of women with breast implants. So, it's a bit of good news and bad news but women with breast implants should not put off having mammograms because of fear that the implants will be damaged or that there is no point in having a mammogram because there is a possibility the implants will obscure the early signs of breast cancer.

NBC Nightly News anchor Brian Williams is featuring Maria Friedman in one of the profiles of people making a difference. Friedman, a breast cancer survivor and cancer prevention advocate, is a remarkable woman and actress, who decided the show must go on despite a breast cancer diagnosis, surgery and treatment. She continued to perform on the Broadway stage in The Woman in White, and even recorded a new CD of songs with composer Stephen Sondheim. During the month of May, you can watch her sing at New York's landmark Carlyle Hotel.

Friedman -- the mother of two -- chose to appear on NBC Nightly News because she wants women to know that they can survive breast cancer and live a full life. She also wants women to get checked and to pay attention to any changes in their body. She found the lump on her own, and because of its location, it would not have been picked up with a mammogram. Friedman emphasized that the breast is a much larger area than most women think of it, going up to the collarbone and wrapping down under the arm.

Billy Bush, co-anchor of Access Hollywood, the daily entertainment newsmagazine that provides coverage of entertainment personalities on television, also keeps a blog. Yesterday, he blogged his recent visit to Padres Contra de Cancer, a children's hospital in Los Angeles. Eva Longoria had invited him to come with her as she is a long-time supporter and visits quite often.

Bush blogs, "I arrived early to walk through the hospital floor, meet the organizers and get acquainted with some of the families whose children were in the fight of their lives. I was a bit nervous and anxious, because above all else, I will never understand why some children have this disease.  It hurts to the core just trying to fathom this injustice."

During his visit, Bush met a little boy named Kevin, who is undergoing chemotherapy treatments and who has decided to set up a lemonade stand to raise money for video games he wants. Bush asked Kevin how much he was charging for a glass of lemonade and he said he was charging $100 dollars a glass. The next day, Bush received an email from Kevin's mother saying that Kevin had decided to slash the price of his lemonade by 90 percent to the incredible sale price of ten dollars a glass. So, if you are looking for a really good deal on a glass of lemonade, contact Padres Contra de Cancer -- they can hook you up.

Celebrity Naked Chef Jamie Oliver, on a quest to transform the eating habits of school children, appeared on NBC's Today Show with Katie Couric this morning to share fun healthy recipes and tips on how to encourage children to eat healthy. Oliver suggested involving your children in meal preparation, from planning the menu -- to visiting the fishmonger in selecting fish for dinner -- to preparing the meal. In the spring cooking school episode, Fake out your family with these healthy dishes, showed Oliver preparing Summer Pan-Baked Salmon that children would not turn down. NBC features the salmon recipe, as well as several others, for viewers online.

In addition, Oliver hosts Jamie's School Lunch Project, which airs on The Learning Channel. This television series covers a range of issues, from diet and obesity, behavior, nutritional standards, food education -- to the need for a clear government policy on school meals and children's diets. I cannot imagine a better long-term cancer prevention plan than teaching children how to eat healthy when they are young. Oliver makes it easy and fun. TLC hosts an online feature of Oliver's show, with tips, recipes and advice. To learn more about Oliver's projects, programs and where to find his blog, go here.

So, Katie Couric is moving to CBS, and Meredith Viera, one of the ABC co-hosts of The View, accepted an offer to replace Couric at NBC. Which left Viera's job at ABC open. Who did Barbara Walters choose as the new co-host? Rosie O'Donnell. What are Walters and ABC thinking? Jerry Springer ratings steeped in controversy is all I can figure out.

Once upon a time, I was a Rosie O'Donnell fan. As a comedian, I thought she was funny. As an advocate for children, I thought she was generous. But she cancelled all that out the day she allegedly told one of her staff, who was battling breast cancer, that "liars get cancer," because apparently, O'Donnell was feeling even more mean-spirited than usual that day. To be accurate, during a lawsuit Rosie magazine publishers filed against O'Donnell for breach of contract -- Cindy Spengler -- who was head of marketing at Rosie magazine, testified that O'Donnell made the remark after a meeting to discuss the magazine's problems. Spengler said O'Donnell told her that her silence in the meeting was tantamount to lying. "You know what happens to people who lie," the witness tearfully quoted O'Donnell as saying. "They get sick and they get cancer. If they keep lying, they get it again.

Before that, I do not think the larger audience had any idea O'Donnell harbored such dark spite in her heart. The statement, while obviously appalling and unforgivable, is also stupefying considering O'Donnell -- at the age of 10 -- lost her mother to breast cancer. But no matter now, as to the why of it all. You can't unring a bell. I am not a huge daytime television viewer, but come September, you can rest assured, no one at my house will be channel surfing ABC. People has the bland noncommittal announcement of The View's choice for new co-host. The Boston Herald has a snarkier version of the story. As a breast cancer survivor, now you have mine.
