Exhaled breath contains chemical clues to what's going on inside the body, including diseases like lung cancer. And devising ways to sense these compounds could help doctors provide early diagnoses -- and improve patients' prospects. Researchers report developing ultrasensitive, nanoscale sensors that in small-scale tests distinguished a key change in the chemistry of the breath of people with lung cancer.

The cost of childbirth and postpartum health care results in significant, ongoing financial hardship, particularly for lower-income families with commercial insurance. About half of people who give birth in the United States are covered by commercial health insurance, which typically requires cost-sharing in the form of deductibles, copayments, and coinsurance.

A new study changes the way we understand memory. Until now, memories have been explained by the activity of brain cells called neurons that respond to learning events and control memory recall. Neurologists have now expanded this theory by showing that non-neuronal cell types in the brain called astrocytes -- star-shaped cells -- also store memories and work in concert with groups of neurons called engrams to regulate storage and retrieval of memories.
