Scientists Discover New Type of Lung Cell

Pulmonary ionocytes (orange) extend through neighboring epithelial cells in the upper respiratory tract of the mouse, to the surface of the epithelial lining; cell nuclei in cyan. Image credit: Montoro et al, doi: 10.1038/s41586-018-0393-7.

Two independent teams of scientists have identified a rare cell type in airway tissue — previously uncharacterized in the literature — that appears to play a key role in the biology of cystic fibrosis, a multiorgan disease that affects more than 70,000 people worldwide. Named pulmonary ionocytes, these cells appear to be the primary source of activity of a gene called cystic fibrosis transmembrane conductance regulator (CFTR), mutations...

An artist’s impression of the collision of two stars, like the ones that formed CK Vulpeculae. The inset illustrates the inner structure of one red giant before the merger. A thin layer of 26Al (brown) surrounds a helium core. An extended convective envelope (not to scale), which forms the outermost layer of the star, can mix material from inside the star to the surface, but it never reaches deep enough to dredge 26Al up to the surface. Only a collision with another star can disperse 26Al. Image credit: NRAO / AUI / NSF / S. Dagnello.

On Earth, the Northern and Southern lights occur when the solar wind (electrically charged particles from the Sun) follow our planet’s geomagnetic field lines to the poles and collide with the upper atmosphere. Mars lacks a global magnetic field, so instead the solar wind piles up in front of Mars in a bow shock, which blocks charged particles from reaching the bulk of the atmosphere. However, in a process first observed by NASA’s MAVEN spacecraft, some solar wind protons can slip past the bow shock by first bonding with electrons from the Martian upper atmosphere to form hydrogen atoms. Because these hydrogen atoms are electrically neutral, they can pass through the bow shock and go on to create an ultraviolet proton aurora on the dayside of Mars.

This mosaic of Cerealia Facula is based on images obtained by NASA’s Dawn spacecraft in its second extended mission, from an altitude as low as about 21 miles (34 km). The contrast in resolution obtained by the two phases is visible here, reflected by a few gaps in the high-resolution coverage. This image is superposed to a similar scene acquired in the low-altitude mapping orbit of the mission from an altitude of about 240 miles (385 km). The increased resolution afforded by the low altitude is revealing intimate details about the relationships between bright and dark materials across the facula, which will help resolve the mystery of its origin. Cerealia Facula is located at about 19.7 degrees north latitude and 239.6 degrees east longitude. Image credit: NASA / JPL-Caltech / UCLA / MPS / DLR / IDA / PSI.
