Australian gold rush started in 1851 when Edward Hargraves and his colleagues found gold near Bathurst, New South Wales.  It had a big impact on Australian economy and development.

Scientists had performed the dream which ancient Alchemists had dreamt — creating gold.  The gold was not visible to anyone as it was in nano size.  However nanoparticles of gold are only created in laboratories but not in nature.  Nanosized were discovered in Western Australia by scientists.  Scientists were searching for nano gold in nature to understand how geological processes transported and deposited gold.  This understanding can help gold explorers to find the new gold field.  Leader author, CSIRO’s Dr Rob Hough, explained that nanosized gold was common in environments where saline water interacts with gold deposits.  The gold nanoparticles were not detected earlier as they are transparent to electron beams.

Scientists achieve major genetics breakthrough

University of Adelaide geneticist Dr Jozef Gecz and a team of Belgium and UK scientists have achieved a major breakthrough in discovering the causes of intellectual disability.

Dr Gecz, a senior researcher who is based at the Women’s and Children’s Hospital in Adelaide, has collaborated with an international research team to reveal that various mutations of a small part of the X chromosome lead to mental retardation.

Man has better chance of being a retard.
