One of the many mysteries of cancer is the ability of tumor cells to survive and grow in spite of poor blood and nutrient flow. Scientists have now systematically mapped the core genes and biological processes associated with the ability of cells to survive nutrient stress.

Study in worms reveals gene loss can lead to accumulation of waste products in cells.

The approach could guide research for inherited blindness treatment in humans.

Treatment-resistant cancers self-destruct when exposed to experimental drug.

People with moderate to severe mid-life anxiety may face a greater risk of dementia in later life, but it's not clear whether treatment for anxiety could curb dementia risk.
