Yahoo shuts pioneering search engine AltaVista 18 years on

Yahoo had acquired the AltaVista technology, index and name when it bought ad firm Overture in 2003.

Internet Corporation Yahoo has finally drawn the curtains on pioneering search site AltaVista this morning.

AltaVista was hugely popular when it was launched in 1995 because it had indexed 20 million webpages and developed its own ‘crawler’ technology that did the job of finding webpages and logging what was on them.

Yahoo had acquired the AltaVista technology, index and name when it bought ad firm Overture in 2003, ABC News reports.

According to the report, Yahoo had announced the shutdown on June 28 adding that if users visit AltaVista website, they will be directed to Yahoo search site.



Aerogel: See-Through, Strong as Steel and Lighter than Air

Despite its incredibly low density, aerogel is one of the most powerful materials on the planet. It can support thousands of times its own weight, block out intense heat, cold and sound – yet it is 1,000 times less dense than glass, nearly as transparent and is composed of %99.8 air. The lowest-density silica-based aerogels are even lighter than air.
Despite its fragility in certain regards and its incredible lack of density, aerogel has amazing thermal, acoustical and electrical insulation properties as illustrated by the images here. A single one-pound block can also support half a ton of weight. NASA continues to find new space-based applications for this incredible material.
An aerogel window one inch thick has the effective insulative capacity of a ten-inch thick glass window system. While it is still expensive and has other limitations, this material – originally developed nearly a century ago but still undergoing experimentation – could prove to be one of the most influential materials of the 21st Century.
Aside from its other capabilities, aerogel also has amazing absorbing abilities. Some speculate it could be the future solution to oil spills. It is also being tested as a possible slow-release drug deliver system for potential human patients.
