The planet in question — HD 189733b — is too hot for the molecules to signal life, but the discovery offers hope for understanding future discoveries of Earth-like worlds, says NewScientistSpace. Researchers from Caltech and University College London used the Hubble Space Telescope to peer at the planet and examined spectral signature of starlight filtered by the planet's atmosphere, to identify different chemicals.

Scientists have discovered that carbon nanotubes have remarkable springy properties, which could make them idea for use in artificial muscles. Currently, electroactive polymers are most commonly used to make artificial muscles, but these lack mechanical robustness. Researchers at Rensselaer Polytechnic Institute tested the nanotubes by repeatedly squashing them between to metal plates. The work is reported in Nature Nanotechnology.

It might sound like a joke, but documents unearthed by New Scientist show that the Pentagon actually funded research into 'non-lethal' bullets that would also hit a target with a dose of laughing gas. That way, they'd not only be stunned but incapacitated by fits of giggles. Another idea was to put stink bombs inside rubber bullets. I guess it would work, but the idea of crowds of rioters giggling uncontrollably while being pelted with rubber bullets is truly bizarre...

Researchers in Japan have developed a display that makes 3D objects solid enough to grasp. The system, created by engineers at Japan's NTT, combines a 3D display with a haptic glove, making 3D items that look real but also feel solid to touch. Two cameras are used to image an object, to make the 3D image. A computer also uses this to render a solid representation. It could be used to inspect products remotely, or even to shake hands with someone on the other side of the world, the researchers say

Hitachi reckons that a simple chemical additive could significantly improve battery life. Alkaline batteries have a positive electrode of manganese oxide and a negative electrode of finely powdered zinc, but zinc oxide forms around these grains of zinc. Hitachi's solution is to replace the zinc with a fine powder of zinc-aluminium alloy, displaces the zinc within the zinc oxide layer making it a much better conductor.

An experimental new type of memory that uses nanosecond pulses of electric current to push magnetic regions along a wire could dramatically boost the capacity, speed and reliability of storage devices. Magnetic domains are moved along a wire by pulses of polarized current, and there location is read by fixed sensors arranged along the wire. Previous experiments have been disappointing but now researchers have found that super-fast pulses of electricity prevent the domains from being obstructed by imperfections in the crystal.

In the future, your place of work (or apartment) may very well spy on you. But that doesn't mean it'll be able to name and shame you for all your nasty habits. Researchers at Mitsubishi Electric Research Laboratory (MERL) have devised a 'dumb' surveillance system that monitors the movements of workers without identifying them individually. The idea is to have a computer system automatically configure the air-conditioning to save money, or illuminate the most appropriate escape signs in an emergency.

According to this article at New Scientist, DARPA is developing a plasma shield that would allow troops to stun and disorientate enemies. The system will use a technology known as dynamic pulse detonation (DPD), which involves producing a ball of plasma with an intense laser pulse creates, and then a supersonic shockwave within the plasma using another pulse. The result is a gigantic flash and a loud bang in a the air.

According to New Scientist's Tech blog, the 2007 Conference on Email and Anti-Spam (CEAS) will feature a live spam-catching contest. Entrants will be treated to a torrent of spam and must use their spam filtering technique to filter out as much as possible, while also letting legitimate messages. My money's on Spam Assassin.

According to New Scientist, Darpa is soliciting proposals for so-called Chemical Robots (ChemBots) that would be soft, flexible and could manoeuvre through openings smaller than their static structural dimensions. They suggest that it could be made from shape-memory materials, electro- or magneto-rheological materials or even folding components. Does this sound like the T-1000 from Terminator 2 to anyone else? Yikes.

Researchers have found a way to propel micro-capsules by attaching S. marcescens bacteria (the type that makes your shower curtain moldy). Researchers at Carnegie Mellon University fixed the bacteria to the micro-capsules and then turned them on and off chemically.
From the article: "In the future, such hybrid swimming micro-robots could even be used to deliver drugs inside the liquid environments of the human body, such as the urinary tract, eyeball cavity, ear and cerebrospinal fluid," Metin Sitti told NewScientistTech.

Researchers at the University of Pennsylvania have developed a 'neural extention chord' by growing neurons attached to a microchip. The chord is made by gradually moving two batches of neurons apart, as they naturally grow towards one another. This biological 'data cable' could then naturally interface with the brain once implanted, the researchers say.

In the future, all gadgets could be coated with tough, diamond-like material. A patent from Nokia — featured in the latest patent round-up from New Scientist — describes a way of infusing plastic cases with a material, structurally similar to diamond, made from coal. Not only is it more scratch and grime-resistant, but it's also cheap and biodegradable. Apparently it also shines like a metal. Nice.

There's an interesting post on NewScientistTech's blog about virtual reality inducing false memories during a recent experiment (pdf). Ann Schlosser at the University of Washington tested students' ability to learn how to use a real digital camera by operating a virtual one. Although those students who used the virtual camera found it easier to remember how the camera worked, they also experienced more 'false memories'. As the post points out, could this be a serious problem for VR going forward?

The UK military recently tested a remote-controlled passenger jet over south-west England. Although the pilot was sitting in the back of the ageing BAC 1-11, he controlled it entirely using the 'UAV Command and Control Interface (UAVCCI)'. This also allowed him to operate several virtual UAVs in a simulated attack scenario. The ultimate goal is for a fighter pilot to control a swarm of attack UAVs alongside his own plane. Next March, a Tornado fighter pilot will do use the UAVCCI to fly the unpiloted BAC1-11 as well as several simulated UAVs, all from the cockpit of his own jet.
