Final moment as star is about to explode ‘caught’

Planetary scientists claim to have for the first time captured the final moments before a star is about to explode, after scanning 25 galaxies.
Astronomers have been cataloguing star systems for three years to try to capture them as they meet their ends. Now, an international team says it has noticed one star system in the Whirlpool Galaxy, which was brightening and dimming in an unusual way, has produced a supernova. The development could help researchers predict when a star may expire in the future as they try to determine whether the change in brightness was linked to the end of its life, the Daily Telegraph reported. Prof. Christopher Kochanek at Ohio State University was quoted as saying, “Our underlying goal is to look for any kind of signature behaviour that will enable us to identify stars before they explode.”

‘Teen sex may hinder brain development’
Having sex during the adolescent years could negatively affect the mood and brain development during adulthood, a new study has claimed. One reason the researchers from the Ohio State University College of Medicines believe could be that during adolescence the nervous system is still in the developing phase that can have broad consequences. “Having a sexual experience during this time point, early in life, is not without consequence,” study co-author John Morris, a doctoral student in psychology at Ohio State, was quoted as saying by LiveScience.
