Review: HTC Desire vs Sony Ericsson Xperia X10

It wasn't too long ago that choosing an Android phone came down to whether you wanted a physical keyboard (HTC G1/Dream

) or not (HTC Magic
). With increasing Android adoption from carriers and handset manufacturers, making the same decision in 2010 is a lot harder. We've put two of the latest Android phones, the HTC Desire and the Sony Ericsson Xperia X10, head to head in our latest versus review - read on for the details. Read More



World's smallest, lightest telemedicine microscope

Making use of novel lensless imaging technology, a UCLA engineer has invented the world’s smallest, lightest telemedicine microscope. The self-contained device could radically transform global health care – particularly in Third World countries – with its ability to image blood samples or other fluids. It can even be used to test water quality in the field following a disaster like a hurricane or earthquake. Read More




Green design gets a second skin

This beautiful architectural proposal from Italian firm StudioDosi is as green as it looks. Submitted in a competition to design a new headquarters for the Province of Parma in Italy's north, the public office space features a double glazed inner skin wrapped in an exoskeleton of "climbing vegetable stripes" which allows natural light to enter the building and boosts ventilation.

Transmission speeds of 100Mbps over 1km on existing copper networks

In an ideal world we would all access the Internet over fiber optic cables that reach right up to the front door to deliver blisteringly fast transmission speeds. Unfortunately, we don’t live in an ideal world and many of us are forced to rely on aging copper network infrastructure. Now, Alcatel-Lucent’s Bell Labs has demonstrated technology that boosts the transmission speeds over two copper pairs to 100Mbps over a distance of 1km. This could see such infrastructure given a new lease of life, satisfying consumer’s need for speed for some time to come. Read More




Fraunhofer developing electric vehicle test platform

With the internal combustion engine dictating vehicle design for over a century the move towards electric vehicles offers manufacturers the chance to completely rethink vehicle design. However, it also presents manufacturers with a whole new set of problems to be overcome. To facilitate the transition to electric cars, researchers at Franhofer-Gesellschaft are constructing an electrically operated demonstration vehicle, the “Frecc0,” which will serve as a scientific integration platform for automobile manufacturers and suppliers to test new electric vehicle components.

Stunning first images from NASA’s Solar Dynamics Observatory

Although we do know some things about the Sun - it's big and hot for example - in many ways it remains a great mystery to scientists. In a bid to shed some more light on our closest star, NASA launched its most advanced spacecraft ever designed to study the Sun in February this year. The goal of the the Solar Dynamics Observatory (SDO) is to help us understand where the Sun's energy comes from, explore its inner workings, and learn more about how energy is stored and released in the Sun's atmosphere. A nice side benefit will also be the capture of stunning images – the first of which have just been released. Read More




3R's A200 is a microscope in your pocket

At the Printable Electronics Exhibition in Tokyo, 3R Systems

was showing off their newest model of pocket microscope, the A200. Unlike the previous Vitiny
model, which shot at 300,000 pixels, the A200 has a 2 megapixel (2,000,000) CMOS sensor and kicks out images of about 1600 x 1200 pixels. Read More



Pedego brings a blast from the past to modern e-bikes

With gas prices climbing and environmental concerns mounting, electric bicycles are becoming more popular than ever. Cycling purists might see them as a bit of an abomination, but look at it this way: they’re really just less-expensive electric scooters, that give you the option of pedaling. Given that there are already a number of brands to choose from, what can a company do to separate their product from the pack? In the case of California-based Pedego, they make retro-funky beach cruisers in a rainbow of colors. Read More




US Navy developing autonomous underwater hull-cleaning robot

Barnacles might seem to be a traditional, almost quaint accoutrement of sea-going vessels, but they’re actually a serious problem. The buildup of marine organisms on a ship’s hull, known as biofouling, can reduce its speed by up to 10 percent. To compensate for the drag, the ship may have to use as much as 40 percent more fuel. Ships have to be lifted into drydock for the removal of barnacles, and sometimes toxic hull coatings are used to prevent them from colonizing. Hopefully, a new innovation may make both of those approaches unnecessary - it’s an autonomous hull-cleaning robot. Read More




Subaru develops advanced stereoscopic vision system for cars

Driving is a sight-response game and as the line between robots and cars begins to blur, cars will develop ever more advanced vision systems. Subaru began fitting a stereoscopic “EyeSight” system to some Japanese market cars nearly two years ago and has just announced a major upgrade. It's reportedly a major improvement, but it's worth thinking about the issues associated with becoming reliant upon systems which take over the responsibility for driving your car. Read More
