Despite smoking's well-known role in causing lung cancer, a significant number of patients who develop lung tumors have never smoked. While scientists are still working to understand what spurs cancer in so-called 'never-smokers,' a study suggests that 78% to 92% of lung cancers in patients who have never smoked can be treated with precision drugs already approved by the Food and Drug Administration to target specific mutations in a patient's tumor.

New treatment for inflammatory bowel disease: Opioids may cure that 'bad gut feeling'

Opioid receptors play key roles in regulating our senses and emotions. Recently, their discovery outside the nervous system raised several questions about the effects of opioids on the immune system. Now, researchers have shown that KNT-127 -- a drug that targets delta opioid receptors -- can reduce pro-inflammatory signals in the colon. Their research highlights the immunomodulatory properties of opioids and indicates their therapeutic potential in inflammatory bowel disease and other related disorders.
