ikenbot: OB Association Stars OB associations are groups of O and B stars that have dispersed to the extent that their mutual gravity no longer holds them together. Although they may be far apart, stars in an association share a common motion in space because they were formed from the same gas cloud. This allows astronomers to easily determine OB association membership stars. Class O stars are very hot and extremely luminous, being bluish in color; in fact, most of their output is in the ultraviolet range. These are the rarest of all main-sequence stars. About 1 in 3,000,000 (0.00003%) of the main-sequence stars in the solar neighborhood are Class O stars.] Some of the most massive stars lie within this spectral class. Type-O stars are so hot as to have complicated surroundings which make measurement of their spectra difficult. Class B stars are very luminous and blue. Their spectra have neutral helium, which are most prominent at the B2 subclass, and moderate hydrogen lines. Ionized metal lines include Mg II and Si II. As O and B stars are so powerful, they only live for a relatively short time, and thus they do not stray far from the area in which they were formed.
neuromorphogenesis: Studying Languages Can Grow the Brain Learning a new language can grow one’s perspective. Now scientists find that learning languages grows parts of the brain. Scientists studied the brains of students in the Swedish Armed Forces Interpreter Academy, who are required to learn new languages at an alarmingly fast rate. Many must become fluent in Arabic, Russian and the Persian dialect Dari in just 13 months. The researchers compared the brains of these students to the brains of medical students who also have to learn a tremendous amount in a very short period of time, but without the focus on languages. The brains of the language learners exhibited significant new growth in the hippocampus and in parts of the cerebral cortex. The medical students’ brains showed no observed growth. The study was in the journal NeuroImage. Interestingly, the amount of growth in the brains of the linguists correlated with better skills—so those with better language skills also experienced more growth in the hippocampus and areas of the cerebral cortex that relate to language. For other students who had to work harder to improve their language skills, the scientists found greater growth in the motor area of the cerebral cortex. Where and how much change take place in the brain are linked to how easily one picks up a language. But it remains to be seen why this is. —Christie Nicholson
