Replicating nano structure of butterfly wings could lead to better solar cells
By Darren Quick
20:19 October 11, 2009 PDT
Researchers have developed a technique to replicate biological structures, such as butterfly wings, on a nano scale. They focused on the tiny nano-sized photonic structures that are found in the insects’ cuticle, and which give insects their iridescence - that slightly metallic sheen that also seems to shift in color depending on the viewing angle. By replicating the biotemplate of butterfly wings, the researchers hope to be able to make various optically-active structures, such as optical diffusers or coverings that maximize solar cell absorption.

Household robots – a burglar's man on the inside?
By Darren Quick
19:34 October 11, 2009 PDT
Until robots rise up and overthrow their puny human creators, one of the main risks comes from the people using the robots. A new study warns that the current crop of household robots presents a serious safety and privacy risk. They make it all too easy for nefarious types to hijack control of the robots and access valuable data - even giving them the ability to watch and listen in on private conversations, and perform remote reconnaissance on a house.

Getac's resistive-type multi-touch technology works with or without gloves
By Darren Quick
02:34 October 9, 2009 PDT
Anyone who has tried to use a multi-touch touchscreen with anything other than their bare skin will know that it’s just not possible, no matter how hard you press. That’s because the capacitance technology used for the bulk of multi-touch devices doesn’t detect pressure, but measures the changes in electrical resistance caused by contact with a conductor – in this case, the human body. That might be annoying in cold climates, but is an even bigger problem in situations that require the wearing of protective gloves. Getac’s line of rugged Tablet PCs will be the first commercially-available rugged computers to solve this problem by offering a multi-touch screen that works with or without gloves. Read More

Helmets are the obvious form of protection for cyclists, and many parts of the world have laws in place making the wearing of them while riding a bike mandatory. But with cyclists being such vulnerable targets on the roads, other protective gear is undoubtedly a good idea - and almost essential for offroaders traversing rugged terrain. The Spine Ergo Flow is a lightweight armor for your spine that is designed to decrease the likelihood of sustaining a serious spinal injury in the event of an accident. Read More
What, exactly, makes a rocket fuel environmentally friendly?
By Darren Quick
22:52 October 7, 2009 PDT
Automobiles aren’t the only vehicles turning to more environmentally friendly fuel sources. As we reported recently, NASA are testing a new type of rocket propellant made of a mixture of water and “nanoscale aluminum” powder they claim could provide a cleaner way to launch rockets, power long-distance space missions and generate hydrogen for fuel cells. A number of readers wondered, not unreasonably, what qualifies a rocket fuel as eco-friendly. We now have a few more answers. Read More
Breathing easier could be as simple as crossing the street
By Darren Quick
20:01 October 7, 2009 PDT
Low emission vehicles, such as the Toyota Prius, promise to dramatically cut levels of noxious fumes on city streets. But, until such vehicles start to dominate the roads, people still have to cope with what spews forth from the tailpipes of their fossil fuel-powered cousins. However, researchers have recently found that pedestrians may be able to reduce the amount of traffic pollution they breathe in simply by crossing the street. Read More

That's him, officer - the Police sketch artist evolves
By Darren Quick
23:59 October 6, 2009 PDT
Human memory is a notoriously unreliable thing that can be easily influenced. That’s good news for criminals and bad news for law enforcement agencies that often rely on eyewitnesses to provide a description of a criminal. Around the world, law enforcement agencies employ sketch artists to piece together faces in a process similar to assembling a Mr. Potato Head toy. The witness describes key features, such as hair length, nose size or sharpness of the chin, and the artist combines them to create a likeness. Research into psychology suggests that this kind of method doesn’t take into account how the memory actually works, so researchers have developed new software that helps witnesses recreate and recognize suspects using principles borrowed from the fields of optics and genetics.

An electron microscope that won't destroy living cells
By Darren Quick
23:19 October 6, 2009 PDT
Instead of light, traditional high-resolution electron microscopes use a particle beam of electrons to illuminate a specimen. However, the particle beam also destroys the samples, meaning that electron microscopes can’t be used to image living cells. Electrical engineers at Massachusetts Institute of Technology (MIT) have proposed a new scheme that can overcome this critical limitation by using a quantum mechanical measurement technique that allows electrons to sense objects remotely without ever hitting the imaged objects, thus avoiding damage.

Brain-to-brain communication over the Internet
By Darren Quick
22:14 October 6, 2009 PDT
Brain-Computer Interfacing (BCI) is a hot area of research. In the past year alone we’ve looked at a system to allow people to control a robotic arm and another that enables users to control an ASIMO robot with nothing but the power of thought. Such systems rely on the use of an electroencephalograph (EEG) to capture brain waves and translate them into commands to control a machine. Now researchers at the University of Southampton have used a similar technique to show it is possible to transmit thoughts from one person to another. Read More
