Warp drive a no go

Science fiction fans know that many seemingly impossible technologies materialise years later — mobile phones, personal computers and of course, human spaceflight, being three examples. However this may not to be the case for warp drive, the idea of travelling through space faster than the speed of light

Home-made Gauss Rifle

From the fun-things-to-do-with-magnets department comes the Home-made Gauss Rifle. It requires a wooden ruler with a groove down the middle to serve as the rail, steel balls that can roll down the groove to use as projectiles, and magnets to store and redirect energy

Morphing DNA makes motor

DNA molecules are prime candidates for helping humans make microscopic machines because they have a long history of assembling things on the molecular scale. Researchers at New York University have taken a significant step forward in being able to instruct artificial DNA molecules to move in specific ways with a method that allows certain portions of DNA to bind to each other, and then release. This reversible binding method allows for control of the shape of a DNA molecule, or machine

Japan plans tearoom for the ISS

Astronauts on board the International Space Station could soon spend their spare time learning the elaborate rituals of the Japanese tea ceremony. Officials at Japan’s National Space Development Agency are planning to include a 13 square foot tea-room in Japan’s section of the ISS, possibly in the Kibo laboratory module, scheduled for launch in 2004

Clothes that know when you’ve been sleeping

Car seats that wake up drowsy drivers, bed sheets that monitor your health, socks that let you know when you are about to do a tendon, vests that trigger an emergency beacon if you are dying of exposure — that’s what an eclectic mix of researchers spent last Friday discussing as part of an Electronic Textiles workshop in Geelong

National Geographic

During a recent quest to hunt down a 17-year-old copy of the National Geographic, I ran into problems contacting the Single Copy Sales department due to bugs in their recently revamped e-mail system. So I’m greatly appreciative to Lisa Walker for both persevering with my continual queries and hunting down an old office copy for me — and then sending it to the other side of the planet gratis

All tied up

The dream of teleporting atoms and molecules — and maybe even larger objects — has become a real possibility for the first time. The advance is thanks to physicists who have suggested a method that in theory could be used to entangle absolutely any kind of particle
