Southwest Airlines has announced the world’s first “green plane,” a Boeing 737-700 that’s 472 lbs. lighter than a conventional model and saves 9,500 gallons of jet fuel per year.

It’s no secret that the airplanes are some of the worst polluting transportation methods available. According to Outside.com, airlines account for about two percent of “all glacier-melting, polar bear-killing emissions released into our carbon-choked friendly skies.”

To lighten the Boeing 737-700’s load, the company is installing recyclable InterfaceFLOR carpet, weight-saving seat covers and life vest pouches, lighter foam fill in the seats and aluminum (versus plastic) seat rub strips.

Tiny crystals could hold the key to creating computers with massive storage capacity, scientists believe.

The crystals could be used as storage devices for desktop computers capable of holding 100-times more data than current systems.

Scientists at the University of Edinburgh have been using low-energy lasers to make salt crystals in gel.

The development could allow users to store a terabyte of data in a space the size of a sugar cube within a decade.

This would be enough to hold the equivalent of 250,000 photographs or a million books.

Physicists at UC San Diego have successfully created speedy integrated circuits with particles called “excitons” that operate at commercially cold temperatures, bringing the possibility of a new type of extremely fast computer based on excitons closer to reality.

Their discovery, detailed this week in the advance online issue of the journal Nature Photonics, follows the team’s demonstration last summer of an integrated circuit—an assembly of transistors that is the building block for all electronic devices—capable of working at 1.5 degrees Kelvin above absolute zero. That temperature, equivalent to minus 457 degrees Fahrenheit, is not only less than the average temperature of deep space, but achievable only in special research laboratories.

Now the scientists report that they have succeeded in building an integrated circuit that operates at 125 degrees Kelvin, a temperature that while still a chilly minus 234 degrees Fahrenheit, can be easily attained commercially with liquid nitrogen, a substance that costs about as much per liter as gasoline.

Should, by some terrible misfortune, Ray Kurzweil shuffle off his mortal coil tomorrow, the obituaries would record an inventor of rare and visionary talent. In 1976, he created the first machine capable of reading books to the blind, and less than a decade later he built the K250: the first music synthesizer to nigh-on perfectly duplicate the sound of a grand piano. His Kurzweil 3000 educational software, which helps students with learning difficulties such as dyslexia and attention deficit disorder, is likewise typical of an innovator who has made his name by combining restless imagination with technological ingenuity and a commendable sense of social responsibility.
