THE latest twist on invisibility cloaks won't hide Harry Potter in the middle of a room, but it might just let spies conceal microphones under the rug or the wallpaper. So called "carpet cloaks" are the first technology to succeed in hiding objects by deflecting light across a range of wavelengths. Two groups described different cloaks last week at the International Quantum Electronics Conference in Baltimore, Maryland. Invisibility cloaks work by deflecting light waves so the light that reaches the eye shows no trace of the hidden object. Conventional optical materials can't do this, but a dozen years ago John Pendry of Imperial College London showed it was possible to bend light around objects by building materials made of components smaller than the wavelength of the light. In theory, the principle will work across the electromagnetic spectrum, but early experiments with invisibility cloaks have been done at microwave frequencies, which have wavelengths in the ce

To protect the meek scrollwheel, the honorable Sony VGP-BMS10 Bluetooth mouse took an oath of loyalty and drew its metal shield. Then a laser was placed in its underbelly to track foe and friend alike. We can only hope that the VGP-BMS10 is as trustworthy as it looks. Otherwise, the mouse is just another premium mouse. Featuring an 800dpi sensor, 30-foot range and PC-only compatibility (which seems odd), Sony's optical knight is available now in Japan for $70. And in other news, I must be Jonesing for my first trip to Medieval Times.

Leading mobile handset manufacturer Samsung launched a low-cost solar-powered mobile phone, and said it was planning to introduce about 20 more models by year-end. The new handset, launched under its low-cost line of products -- "Guru" -- at a price of Rs 2,799, has a solar panel on the back, which can be used to charge the battery anywhere the sun is shining. "We have developed this phone keeping in minds the needs of the consumers, especially for people in areas where the electric supply is unstable," said J S Shin, president and chief executive of Samsung, Southwest Asia. The phone, christened the "Guru E1107", can provide around 5-10 minutes of talk-time with one-hour of solar charging when the handset is turned off and sunlight has adequate intensity. "Solar charging can give you enough time to make few important calls when there is no electricity or you are not close to a plug point," said Sunil Dutt, country head of Samsung India. The batt

New iPhone is here, iPhone 3G S. iPhone 3G S offers as many as 100 new features and more than double the speed of the earliest version. Plus, it comes with a price cut. Seems like users have got all they wanted and wished for in the new gadget. Not really! iPhone 3G S though offers a lot, still leaves a lot wanting. The revamped iPhone disappoints users on many counts, some which were on top of their wishlist for the new iPhone. Here are the 9 things that disappoint many users in iPhone 3G S. Apple products are known for their design. Apple iPhone too scores high on looks. But a change is always refreshing. So, a change in looks was high on users' wishlist. However, the new iPhone 3G S disappoints with almost nothing new in terms of appearance. The phone looks exactly same like its predecessors with same dimensions and screen display. iPhone 3G S, in both 16GB or 32GB variants, will be available in black and white colour options. Apple finally upgraded iPhone's camera megapixel

Bike, stroller or wheeled trebuchet? Whatever it is, the Taga takes kid-carrying in a new direction. I just can't help thinking those two smiling kids are one wheelie away from joining the ISS. Luckily for the kids, the Taga trike stroller comes with a range of custom safety options and accessories, like the pictured double child seat, car seat, basket, and wooden double-seat trailer. Oh, and it transforms from trike to stroller in a few seconds, which is actually incredibly innovative and convenient. I'm going to go ahead and assume you take little Timmy out first. The 44 to 64-lb. Taga kit tops off with a Shimano gear system (found on most mid-range bicycles), as well as front, rear, and parking brakes. The whole kit folds down to car trunk size. Again, take Timmy out first. Europe only for now with a sky-high $2,500 base price.

This next product is for those who want one of those “sexy” bedrooms. You know, the type with the silk sheets, the bearskin rugs and the tiger and leopard print blankets. Yeah, the Luminex Fiber Optic Bed Covers would make a lovely edition to a “love bedroom”. Who wouldn’t be dazzled by bed covers that glow in the dark? Now all that is missing is the Barry White music. “Ooh baby baby, your love’s so good it makes the sheets glow”. The glow effect is produced by fiber optics sewn directly into the covers themselves, and it has to be plugged into the wall for power. In case you are wondering, this doesn’t work as an electric blanket in the sense that it raises the temperature. As for how to wash these covers, I believe they are hand washable with natural soap. It doesn’t look like you have to worry about getting these bed covers wet. So if you or your partner spill the champagne, no problem! You realize that this lightshow will cost you. A 63 x 78.8 inch (160 x 200 cm) cover costs about
