V For Vendetta
Set against the futuristic landscape of totalitarian Britain, V For Vendetta tells the story of a young working-class woman named Evey who is rescued from a life-and-death situation by a masked man known only as “V.”
Profoundly complex, V is at once literary, flamboyant, tender and intellectual, a man dedicated to freeing his fellow citizens from those who have terrorized them into compliance. He is also bitter, revenge-seeking, lonely and violent, driven by a personal vendetta.

Bacteria could power tiny robots
Researchers at Rice University and the University of Southern California have embarked on a project to harness the power of Shewanella oneidensis, a microorganism that essentially spits lightning. Rather than consume oxygen to turn food into energy, Shewanella consumes metals.
The waste product of its metabolic process comes in the form of excess electrons stripped from the metals but not recombined in subsequent chemical reactions. The bacteria lives in soil, water and other environments and can extract its necessary nutrients from a variety of materials.

Methanol-powered artificial muscles
Methanol-powered artificial muscles have been created by researchers aiming to create battery-free robotic limbs and prosthetics.
"One day you could find yourself sitting in a bar next to a humanoid robot, who is taking a shot of vodka to give himself the energy to go to work," jokes Ray Baughman, a nanotechnologist at the University of Texas at Dallas, US.

Cyber-insect army
The Pentagon's defence scientists want to create an army of cyber-insects that can be remotely controlled to check out explosives and send transmissions.
The idea is to insert micro-systems at the pupa stage, when the insects can integrate them into their body, so they can be remotely controlled later.

Nanodevices That Assemble Themselves
Imagine unrolling an electronic newspaper that's automatically updated via the Internet. Or cheap roof shingles that double as solar panels. These are just two technologies that could become possible with the advent of plastic electronics made from tiny components that assemble themselves. UC Berkeley chemical engineer Rachel Segalman is conducting the fundamental research that could help make this nanoscale dream a reality. In December, Segalman's efforts earned her a National Science Foundation CAREER Award.

Mental typewriter
A computer controlled by the power of thought alone has been demonstrated at a major trade fair in Germany.
The device could provide a way for paralysed patients to operate computers, or for amputees to operate electronically controlled artificial limbs. But it also has non-medical applications, such as in the computer games and entertainment industries.
The Berlin Brain-Computer Interface (BBCI) – dubbed the "mental typewriter" – was created by researchers from the Fraunhofer Institute in Berlin and Charité, the medical school of Berlin Humboldt University in Germany. It was shown off at the CeBit electronics fair in Hanover, Germany.

Unintelligent Design
Few things on Earth are spookier than viruses. The very name virus, from the Latin word for "poisonous slime," speaks to our lowly regard for them. Their anatomy is equally dubious: loose, tiny envelopes of molecules—protein-coated DNA or RNA—that inhabit some netherworld between life and nonlife. Viruses do not have cell membranes, as bacteria do; they are not even cells. They seem most lifelike only when they invade and co-opt the machinery of living cells in order to make more of themselves, often killing their hosts in the process. Their efficiency at doing so ranks them among the most fearsome killers: Ebola virus, HIV, smallpox, flu. Yet they go untouched by antibiotics, having nothing really biotic about them.

Nanotube networks conjured on crystals
The key to instantly assembling intricate networks of nanotubes has been discovered by scientists armed with some of the most sophisticated microscopes in the world. The phenomenon may one-day help create tiny nano-circuits that let electrons pass through nano-pipes instead of along silicon wires.
Erdmann Spiecker and colleagues at Lawrence Berkeley National Laboratory (LBNL) in California, US, along with Wolfgang Jäger at Christian Albrechts University of Kiel, Germany, used several high-powered microscopes to study a nanoscale phenomenon previously observed in the laboratory but not well understood.

Saab Aero-X Concept
A week before its debut at the 2006 Geneva Motor Show, pictures of the gorgeous Saab Aero-X have leaked onto enthusiast websites across the internet. This two-seat siren boasts the sexiest shape ever seen on a Saab. The opening canopy is certainly a head turner, even if it may be a too-obvious attempt to play up the brand’s aircraft heritage. The wheels are killer eleven-spoke beauties, and all lighting, inside and out, is LED. Alas, a sexy new sports car is not in the Saab product plan. But let’s hope the Aero-X signals the design direction for future Saabs.
