Study IDs key protein for cell death, offers way to kill cancer cells by forcing them into programmed-death pathway
When cells suffer too much DNA damage, they are usually forced to undergo programmed cell death, or apoptosis. However, cancer cells often ignore these signals, flourishing even after chemotherapy drugs have ...

Decoding 'noisy' language in daily life: Study shows how people rationally interpret linguistic input
Suppose you hear someone say, "The man gave the ice cream the child." Does that sentence seem plausible? Or do you assume it is missing a word? Such as: "The man gave the ice cream to the child."

A different view of cancer cells: New study measures physical changes in tumor cells as they become metastatic
Most cancer deaths are caused by metastatic tumors, which break free from the original cancer site and spread throughout the body. For that to happen, cancer cells must undergo many genetic and physical changes.
