In an effort to help surgeons identify and remove brain tumors, scientists have developed a paint that is attracted to specific channels on cancerous cells. The hope is that with this paint, doctors can more accurately remove just the tumor and not any healthy brain tissue. By sparing the surrounding healthy brain tissue, patients will have fewer symptoms after surgery. Read more at NPR’s coverage: Why Painting Tumors Could Make Brain Surgeons Better

How far would you go to avoid getting a certain type of cancer? How far would you go to avoid getting it again? In Facing Cancer, a Stark Choice, New York Times writer Tara Parker-Pope talks about the dramatic increase in women with breast cancer or at risk of breast cancer seeking to have healthy breasts removed. Commentator Jeanne from Ohio suggests that cosmetics are also a factor.
The New York Times summarizes two recent papers on melanomas, the most dangerous type of skin cancer, that provide strong evidence that such cancers start not with mutations in genes, but mutations in the DNA regions that control them. The vast majority of our human genetic code comprises of these and other non-coding regions of DNA; what was once dismissed as mostly ‘junk DNA’ might be better called ‘dark matter’, considering how much we still have to learn about their function.

The HIV virus causes AIDS, one of the top ten causes of death worldwide. It is also the surprising key to a new cancer treatment with revolutionary promise. The New York Times tells the story.
