Washington, April 24 : Astronomers have discovered large galaxies that have not changed much in size for the last 9 billion years, which suggests these cosmic giants were born 6-7 billion years earlier than expected.
The most popular model for galaxy formation is a bottom-up or hierarchical model in which small galaxies gradually develop into larger ones over a long period of time.
The model predicts that smaller galaxies would merge to form larger ones, growing to 90 percent of their size about 11 billion years after the Big Bang.
Washington, Apr 24 : Scientists have found that a novel compound could treat addiction by warding off memories linked with the time of prior drug use.
Despite being abstinent for long periods of time, many addicts remain vulnerable to their own memories of drug use in the past.

Washington, Apr 24 : An international team of scientists has successfully sequenced cow's genome, thus paving the way for more sustainable food production.
A research team involving 300 researchers from 25 countries spent six years mapping and analysing the genetic make-up of a Hereford cow, named L1 Dominette.
The findings of this study provide the means to select animals with a smaller environmental footprint, particularly animals with less greenhouse gas emissions.
