YouTube - Charlie Rose: August 23, 2002
The interview with Stephan Wolfram from 8/23/2002 is interesting and starts at about 14:25.
That said, it is also interesting to see the latter half of the Jim Lehrer interview (which is just prior to Wolfram's segment) to hear how he and Charlie Rose discussed Iraq and the issues of the day (8/23/2002).

Copy That
"Identical twins may look alike, but their DNA is not the same as long thought, a new study finds. Moreover, each twin grows more genetically distinct over time. Aside from maybe giving forensic investigators a way to tell which twin committed a crime, these recent findings highlight just how changeable human genomes might really be, twins or not.
Identical, or monozygotic, twins result when a fertilized egg, or zygote, splits in two. Because they derive from the same cell, such twins are generally assumed to be physically identical except for features shaped by environmental factors, such as fingerprints, and by womb conditions."

Cancer Therapy Without Side Effects Nearing Trials
A promising new cancer treatment that may one day replace radiation and chemotherapy is edging closer to human trials.
Kanzius RF therapy attaches microscopic nanoparticles to cancer cells and then "cooks" tumors inside the body with harmless radio waves.
Based on technology developed by Pennsylvania inventor John Kanzius, a retired radio and TV engineer, the treatment has proven 100 percent effective at killing cancer cells while leaving neighboring healthy cells unharmed. It is currently being tested at M.D. Anderson Cancer Center in Houston.
“I don’t want to give people false hope,” said Dr. Steve Curley, the professor leading the tests, “but this has the potential to treat a wide variety of cancers.”
Modern cancer treatments like radiation and chemotherapy have proven remarkably effective at treating many cancers, especially in combination, but are plagued with toxic side effects. These treatments kill healthy cells as well as cancerous ones.
Kanzius RF therapy is noninvasive, and uses nontoxic radio waves combined with gold or carbon nanoparticles, which have a long history of medical use.
