One of these worrisome organisms is anthrax, which has al...
Restoring silenced suppressor gene kills lung-cancer cells
A new study suggests that restoring a gene often silenced in lung cancer causes the cells to self-destruct. The findings could lead to a new strategy for treating the disease.
The research focused on a gene known as WWOX, which is lost or silenced in a large majority of lung cancers, and in canc...
Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue
