The newest pre-release code name for Firefox is Namoroka, named for a park in the northwest section of Madagascar. Famous for its Karst topography (or Tsingy as it is described in Malagasy), Namoroka is full of caves, canyons and natural swimming pools. Namoroka is also home to eight species of adorable lemur.


Taiwan unveils super-tiny microchip

Taiwan has developed tiny microchips that could lead to lighter and cheaper laptops or mobile phones, researchers and observers said on Wednesday.

State-backed National Nano Device Laboratories in northern Hsinchu city said it had succeeded in packing more transistors into smaller chip space than anyone else so far.

“Electronic gadgets like cell-phones and laptops could become smaller, lighter and cheaper with this technology,” Yang Fu-liang, the lab’s chief, told AFP.

First Passenger Flight Powered by Biofuel–But Are the Petroleum Alternatives Ready to Takeoff?

Dutch airline KLM has completed a fifth jet biofuel test flight—and the first with passengers other than flight crew. Using a 50–50 blend of regular jet fuel and biofuel refined from camelina oil in one of its four engines, the flight carried 42 “observers” for an hour on November 23 from Amsterdam’s Schiphol Airport, enough to fill business class, according to chemist Jennifer Holmgren, who was on board.
