An X-ray superflare from an infrared protostar
Article Abstract:
X-ray observations of one of the star-forming regions situated closest to Earth have produced evidence of many X-ray sources located around two of the most dense molecular cores where star formation is currently taking place. A specific study has been made of YLW15, which showed a strong flare during X-ray observations. It is likely that the X-rays are not formed by the type of magnetic activity which takes place on the Sun or on other young low-mass stars. The X-rays are probably linked with activity in the circumstellar accretion disk or within the envelope.

Panspermia, spores and the Bacillus subtilis genome
Article Abstract:
The complete sequence of the Bacillus subtilis genome is a significant contribution to the field of genetics research. It will help scientists to understand many physiological processes including sporulation regulation, cell division and gene expression. Evidence indicates that some genes on the B. subtilis genome are controlled in groups. Asymmetric division and symmetric division in binary fission are compared.
