Ubiquitous Multi-Gigabit Wireless Within Three Years 152

Posted by Zonk from the now-where-is-my-hud dept.
Anonymous Howard passed us a link to the Press Escape blog, and a post about the future of ultra-fast wireless connectivity. Georgia Tech researchers unveiled plans to use ultra-high frequency radio transmissions to achieve very high data transmission rates over short distances. In a few years, the article says, we'll have ubiquitous multi-gigabit wireless connectivity, with some significant advances already under their belts. "GEDC team have already achieved wireless data-transfer rates of 15 gigabits per second (Gbps) at a distance of 1 meter, 10 Gbps at 2 meters and 5 Gbps at 5 meters. 'The goal here is to maximize data throughput to make possible a host of new wireless applications for home and office connectivity,' said Prof. Joy Laskar, GEDC director and lead researcher on the project along with Stephane Pinel. Pinel is confident that Very high speed, p2p data connections could be available potentially in less than two years. The research could lead to devices such as external hard drives, laptop computers, MP-3 players, cell phones, commercial kiosks and others could transfer huge amounts of data in seconds while data centers could install racks of servers without the customary jumble of wires."

Humans Evolved From a Single Origin In Africa 461

Invisible Pink Unicorn writes "Researchers at the University of Cambridge have combined studies of global human genetic variations with skull measurements worldwide to show conclusively the validity of the single origin hypothesis. The alternative hypothesis contended that different populations independently evolved from Homo erectus to Home sapiens in different areas. The lead researcher explains, 'The origin of anatomically modern humans has been the focus of much heated debate. Our genetic research shows the further modern humans have migrated from Africa, the more genetic diversity has been lost within a population. However, some have used skull data to argue that modern humans originated in multiple spots around the world. We have combined our genetic data with new measurements of a large sample of skulls to show definitively that modern humans originated from a single area in Sub-saharan Africa.' The article abstract is available from Nature."
