First accepted Submitter Zimanyi wrote Being the start of the school year, teachers of my children invariably ask if all parents have special skills they may have for students. As a software engineer, I want to make a presentation to the classes to develop software.

The difficult part is a presentation entertaining, inspirational, easy enough for students in second and fourth to grasp. Has anyone been brave enough to attempt such a thing? Are there any kid-tested packaged presentations freely available? Would it be better to present the development of a simple game? Web page? Any advice is welcome.

Submitter JoshuaZ first time accepted, writes Astronomers have discovered an unusual small star. SDSS J102915 172927 is a small, faint star with very few elements other than hydrogen or helium.

The composition of the star is surprising ( pdf) from the standard theories of star formation requires heavier elements in smaller stars, to allow stars to be heavy enough to meet. Perhaps the most unusual of the star is non – complete detection of lithium would be expected in a star of this size.

The only items created shortly after the Big Bang were lithium, hydrogen and helium and the star must have lithium levels much higher because they must closely match with the levels that would have been formed shortly after the Big Bang.

This is a good time to be a fan of the stylus. Not only Samsung has launched its friendly writing Slate Series 7 and note Galaxy tablets, but LG is to align the stylus in the lounge with its new series of plasma TVs PenTouch. Available in two varieties 50 inches and 60 inches, each TV comes with a pair of stilettos that you can touch or control the TV and included software such as a calendar and a photo gallery, or just draw on it to the content of your heart. As if this were not enough, the high-end 60-inch model is a 3D TV, and include a pair of active glasses – it will run you $ 2,199, while the non-3D models come to $ 1,699 and $ 1,099. Unfortunately, you will also have to provide your own Windows PC to take full advantage of this feature touch.

We have known that Bell aims to make the leap to LTE for nearly three years , but the Canadian carrier has kept incredibly silent on when or how he would pounce. If you believe an anonymous source, that silence may be coming to an end: the company will supposedly launch its 4G network soon and is rumored to have a phone and a tablet prepared to launch immediately. Devices suspects? None other than the Samsung S Galaxy and Galaxy II LTE tab 8.9. If this happens later in the fall, such an approach would put Bell in the race to become the second carrier in Canada to adopt the standard next-gen – TELUS and SaskTel are expected to upgrade next year – which gives the defenders of choice for wonderful things to expect over the next twelve months.

Zothecula writes While financial contributions are certainly a great help for practitioners of health care in developing countries, one of the things they really need is a robust, portable, low cost of equipment medical infrastructure is compatible with an often limited at the local level. Several such devices are under development as a surgical lamp batteries, a centrifuge-based salad-spinner, and a baby who uses hot wax. UCLA working on another appropriate technology in the form of a small inexpensive microscope that uses holograms, instead of lenses to the image of what can only be seen by the human eye.

If these clock radios this sound familiar, because their creator, Tivoli Audio, has been spitting about the same thing for 11 years . Their guts, at least, have changed over time, and here at IFA company has two models – the PAL + mobile and stationary over the model 10 + – the two hinges on the support for digital radio. Each is compatible with DAB +, DMB and DAB, in addition to good old FM, has two alarms and support five presets for each band. The main difference is that the PAL + is weatherproof and battery, rated over the last three and a half hours unplugged. At £ 1.85 it’s still heavy enough that we never throw in a briefcase, but in a world where it costs less money or not we could take to the beach. You can, if you were so inclined, use the included remote control to navigate the user interface, but there is also a scroll wheel up top – a nice idea, we thought, until you go realize that pushing the button in the middle to scroll through each menu gets boring quickly. As for audio quality, the speakers are powerful enough that their sounds could rise above the din of the showroom, but we could still hear some tinniness come through. The pair are available now, get 299 million (£ 299) and $ 399 (£ 399), respectively, which means that HD radio or not, are always glorified alarm clocks.

Written outline of the NASA reports that the occasion seemed unstoppable robotic geologist is to find things to Endeavour crater that has never seen before, adding new life to a mission that has already been epic.

Observations’ suggest that exposures of rock at the date of Endeavour’s rim from the beginning in the history of Mars and include clay minerals that form in the less acidic wet conditions possibly favorable for life.

In a conference call today, one researcher compared this new mission exploration phase of a new mission as a whole.

Almost two years after AT and T launched its A-List Rollover with plans to become more competitive against the likes of T-Mobile , Alltel and Verizon , the carrier decided to nix the public from today. After receiving the screenshots and a note detailing the leaks intentions Ma Bell, we have achieved to company representatives, who confirmed that these plans are actually going. While new customers will no longer be able to benefit from a pool of five or ten digits (depending on plan) to call all they want, anyone currently using the service will be purchased in. One more warning: plans switching frequency of the individual to the family (or vice versa) can wipe the function A-List off, so proceed with caution. Head here to read AT and T official statement on this issue, as well as some shots of the note of a leak.
