An extremely bright star in the Kinman dwarf galaxy is no longer detectable, and astronomers aren't sure what happened to it.

The process of dead neurons being cleared away in the brains of mice has been captured on video for the first time. "[I]nducing a single cell to die allows us to study what is happening right after the cells start to die and watch the many other cells involved," said Jaime Grutzendler, a co-author of a study on the process published in Science Advances.
Microscopic lenses fashioned from a type of spider silk called dragline silk can be used to take high-resolution images inside the body, according to findings published in the Journal of Applied Physics. The lenses would be safe because they are made of nontoxic materials, say researchers.
The Loma Linda University School of Medicine in California has been awarded a $3.05 million grant from the National Heart, Lung and Blood Institute to study maternal hypoxia. Research will focus on how oxygen deprivation affects both the mother and the baby during pregnancy.

Giant star spots, similar to sunspots, may have been the reason behind unusual dimming last year of the red supergiant star Betelgeuse, according to findings scheduled to be published in The Astrophysical Journal Letters. The blotches in Betelgeuse's photosphere, the part of its surface that shines, cover up to 70% of its surface, researchers say.
