Hospital stays are not much fun for anybody, especially for children with life threatening illnesses. The constant stream of nurses and doctors, staying cooped up in tight quarters and not feeling well take a toll on young people. For young Kelsey Bohman, who spent the better part of a year at Denver Children's Hospital, the tedium of so many long hospital hours gave her the inspiration to turn the monotony into fun.

Kelsey and her family came up with the concept of a marshmallow launcher to replace the standard spirometer respiratory device used to improve her pulmonary health. The launcher has a loading area for the small puffs and then the patient is required to blow in one end to shoot small marshmallows across the room. The action perfectly imitates the breathing techniques used in a regular spirometer.

The marshmallow launchers retail for just under $9.00 a piece with all proceeds going to the Kelsey's Kids Foundation. Not only do these toys bring an element of whimsy into an environment that often lacks fun for young people, but they help to improve health. A pretty clever idea.

It's been a rough road for former Boise State basketball player Coby Karl, son of Denver Nuggets coach George Karl. The younger Karl, 23, had his thyroid removed 13 months ago due to papillary carcinoma, a treatable form of cancer. And he returned to the operating room just last week for the removal of cancerous lymph nodes.

Karl's recent surgery, intended to take two to three hours, lasted for seven hours. This worried Dad.

''When it goes longer and longer, you always think the worst, and start worrying about things like being under anesthesia that long and all the nightmares you have about surgeries,'' George Karl said.

But it turns out Coby was just fine -- doctors just wanted to be thorough -- and the ambitious young man plans to play ball as soon as possible.

Coby is expected to remain inactive for 10 days to two weeks. But after that, he is free to do whatever he wants. And what the 6-foot-4 guard wants to do is start working out in hopes of getting drafted by an NBA team.

''He is anxious to get into the NBA thing and celebrate basketball by trying to make it in this league,'' his dad says.

Boise State basketball player Coby Karl, son of Denver Nuggets coach George Karl, had surgery 13 months ago to remove his thyroid after he was diagnosed with papillary carcinoma, a form of treatable cancer. And while Karl received chemotherapy to kill off any lingering cancer cells, he must undergo cancer surgery once again.

Karl, who plans to play in the NABC All-Star game in Atlanta on March 31, will return to Boise on April 2 for surgery to remove cancerous lymph nodes.

The lymph node cancer was identified in January, but Karl, 23, kept his condition private until his team lost to New Mexico State in the Western Athletic Conference tournament semifinals. This ended the Broncos' season. And now begins Karl's second go-round with cancer.

You may remember Karl as one of last year's NBA draft hopefuls. He worked out for three teams, including his dad's team, but eventually withdrew his name from the draft and returned to Boise State for his senior year.

When Patsy Ramsey passed away from a recurrence of ovarian cancer two months ago, many felt she died under the shadow of suspicion concerning her possible involvement in the murder of her six-year-old daughter JonBenet, whose beaten and strangled body was found by her father John Ramsey in the basement of her family's home in Boulder, Colorado.

At the time of Patsy Ramsey's death, the family attorney Lin Wood said, "I think people will remember Patsy as being someone who was falsely accused in connection with the death of her daughter when she should be remembered for being an incredibly loving mother, wonderful wife, and person who showed great courage in fighting a vicious disease over the last many years."

Today, breaking news reveals that a suspect has been arrested in the murder of JonBenet. Confessing to elements of the crime, the 42-year-old American second-grade school teacher John Karr was apprehended in Thailand.

John Ramsey confirmed in a written statement that Patsy was aware of the authorities interest in the suspect and she died knowing that the case was about to be solved and the murderer of her child was about to be brought to justice. She did not leave this world not knowing.

New CBS Evening News anchor Katie Couric is on a six cities tour to connect with viewers and promote colon cancer awareness to encourage colon cancer screenings. 

On Tuesday, Couric was in Dallas to attend a benefit luncheon for the American Cancer Society. According to reports, most of her talk was about her husband Jay Monahan's colon cancer diagnosis, treatment and death. She is quoted as saying, "He felt invincible, immortal, before doctors found that he not only had colon cancer but also that it was at an advanced stage, taking over his liver." She described Monahan's last day and the moment of his death. There were many tears in the audience.

Couric expressed the feelings many cancer patients and their families feel when the diagnosis of cancer is given. "Suddenly you need to have a medical degree to deal with all the options," she said. One of the reasons she worked to open The Jay Monahan Center for Gastrointestinal Health, named in Monahan's honor, was because she wanted to create the kind of center for others that both her and her husband would have appreciated when he was first diagnosed with cancer. 

"It was a very lonely and isolating experience and very harrowing to go from one specialist to another. Having this comprehensive center full of compassionate caregivers all under one roof would have been a wonderful place for us to go. The opening was a bittersweet occasion, but the center is going to be incredibly helpful to thousands of families and what can be better than that?"

Couric began her six cities tour in Tampa, Florida. Today she was in Dallas and plans stops in Minneapolis/St. Paul, Denver, San Diego and San Francisco. She takes over for CBS Evening News Bob Schieffer on September 5.
