Supercomputing for a New Generation

Over the past few years, I have been very interested in new technology and the future advancements it may bring to business owners & their industries.

This ‘technology think-tank’ group, known as Fireseed, collaborating with other techs in the Wisconsin area, plans to build a Supercomputer. In fact, this Supercomputer will be one of the top 500 in the world. Its conceptual name is the FS3...

US scientist says he created first 'artificial life form'

Fast evolution observed in butterflies

Scientists reported that they had documented very fast evolution in the butterfly species Hypolimnas bolina. After infection by Wolbachia, the fraction of the population that was male dropped drastically to about 1% of the total population. However, after approximately ten generations (about a year) the male population had rebounded to about 39% of the overall population. In the case of H. bolina, infected females were unable to have male offspring since the male embryos died early on....
