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

The new, non-invasive treatment is described in a study published in the Aug. 1 online edition of the Proceedings of the National Academy of Sciences (PNAS). "One of t...

VCU study shows hormone-like molecule kills cells that cause inflammation in allergic disease

Virginia Commonwealth University immunologists studying mast cells, known to play a central role in asthma and allergic disease, have identified a hormone-like molecule that can kill these cells by programming them to die in studies with mice. The findings move researchers another step closer to...

Study: Harmless virus kills some cancers

Six days is all it takes for a common, non-disease-causing virus to kill cervical, breast, prostate and squamous cell cancer cells in laboratory cultures, according to Penn State College of Medicine researchers.
