MIT Injects Nanotubes To Help Fight Cancer 58
CWmike writes to tell us that researchers at MIT have found a way to wrap nanotube sensors in DNA to detect the results of chemotherapy. The sensors are able to detect whether the drugs are attacking their targets or healthy cells. "Cancer researchers have long been trying to figure out a way to better deliver drugs to cancer cells without blasting surrounding cells as well. The Stanford researchers devised a way to use single-walled carbon nanotubes as targeted medicinal delivery vehicles. By better targeting the chemotherapy, less of the drug needs to be injected into the patient for cancer treatment. And that would reduce the side effects of chemotherapy treatment, such as nausea, hair loss, weight loss and fatigue."

That was my first thought when I read this. From the article, though:
The sensors, which can detect chemotherapy drugs as well as toxins and free radicals, are carbon nanotubes that scientists have wrapped in DNA so they can be safely injected into living tissue, according to a release from the university.
I guess the wrapping process eliminates the danger? At least the nanotubes don't end up free-floating.

Only of certain radii and lengths similar to asbestos. I visited SouthWest nanotechnologies and they said they have the ability to control both of those in their process, I'm sure many other processes have that ability as well. See verification of that here [swentnano.com].

Our natural metabolic processes create carcinogens and other chemicals that damage cells, cause aging, etc. These things really are unavoidable (although there are still things which will cause cancer more than others.

After 30 years of reading science news, I'm not holding my breath for cancer. The facts are pretty much the same. If you get small cell lung cancer, you have a 90% chance of dying. John Wayne died of it, and if you get it, you will too.
Bone cancer, pancreatic cancer, all of those are pretty much fatal as well.
Others are not so fatal, but early treatment matters. Breast cancer is one. If you get a cancer that you can and do survive, you'll probably have lifelong health problems as a result, as much from the treatment as the cancer itself, and you won't ever really be completely cured.

Same is true for many other forms. Cure and/or survival rates have been going up, even for the previous "incurable" forms.

As a cancer survivor going on five years now, I wouldn't necessarily say others should expect health problems as the result of their treatment. The chemo I went through was cardiotoxic, but if you're smart and dedicated, you can mitigate the risk for long term problems.
I've become a fairly avid runner in the past few years as a way of keeping my heart strong. The last time I went in for a checkup, my bp was a very good 112/67, and I have better cardio conditioning than ever. I'll need it since I'm going to be running a marathon in a little over 3 months.
That said, here's my plug for charitiable donations to the Leukemia and Lymphoma Society [teamintraining.org]. Every bit helps! Chemo and radiation suck; help fund the research towards curing blood cancers! :)
