Microscopic view of coughed-up mucus may be new biomarker for cystic fibrosis progression

Researchers have been studying mucus in the lungs of cystic fibrosis patients, and their primary goal was to design inhalable therapeutic nanoparticles that cross the cystic fibrosis mucus barrier in the lung. But the work recently led the researchers to the unexpected discovery that mucus appears to change as the disease progresses; the mobility of these nanoparticles could vary widely in mucus from different patients.

How the brain controls sleep

Neuroscientists have discovered a brain circuit that can trigger small regions of the brain to fall asleep or become less alert, while the rest of the brain remains awake. The researchers believe this may help the brain consolidate new memories by coordinating slow waves between different parts of the brain, allowing them to share information more easily.

Ductal carcinoma in situ treatments evolve over 20 years, but cancer death rates vary little

Treatment patterns for ductal carcinoma in situ (DCIS) have shifted since the 1990s, with more U.S. women opting for lumpectomy in combination with radiation rather than single-breast mastectomy, according to a study. But the researchers also found an increased tendency for women to seek removal of both breasts, despite their analysis that cancer survival rates remained similar regardless of the form of treatment.
