    Swiss engineers have invented a pacemaker based on an clockwork wristwatch which is powered by the motion of the heart. The prototype, which has been successfully tested in pigs, could mean that patients no longer have to undergo repeat surgery when the batteries in their device run out. The invention, presented to the European Society of Cardiology Congress in Barcelona, is based on the concept behind a self-winding wristwatch. Currently pacemakers, which are used to help the heart beat more regularly, need to be replaced on average every seven years, when batteries fail More than 40,000 people a year are fitted with pacemakers in England. The devices are used for patients with unusually fast, slow or irregular heart rhythms. The new model, stitched directly on to the heart, is based on the concept of automatic clockwork developed by Swiss watchmakers in 1777 and generates electrical current using the movement of heart muscle.  Automat...

  Mercedes-Benz has just pulled the wraps off of a wild new concept car that was inspired by the 2009 movie Avatar called — what else? — the Mercedes-Benz Vision AVTR. Designed with help from Avatar director James Cameron, this car is not the sequel that Cameron has promised .   VISION AVTR by Mercedez-Benz is an advanced vehicle transformation. Mercedes- Benz Introduces New Concept Car Inspired by the Avatar Film. Inspired by the James Cameron blockbuster Avatar, the vehicle showed off some of Mercedes-Benz's wildest ideas for what the future of four-wheeled mobility might look like and the answer is, it thinks the future of design is biological.    This concept vehicle embodies the vision of Mercedes-Benz designers, engineers and trend researchers for mobility in the distant future.   completely without emissions.   With its four high-performance and near-wheel-built electric motors, the VISION AVTR embodies a particularly agile impleme...

  Augusta Ada King, Countess of Lovelace (née Byron; 10 December 1815 – 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She   is often considered to be the first computer programmer! Lovelace was the first to recognise the full potential of a 'computing machine', suggesting it had applications beyond pure calculations.   (In 1843Ada Lovelace wrote in her notes for a translation of a French article about the Analytical Engine how the machine could be used to follow a program to calculate Bernoulli numbers. For this, she has been called the first computer programmer.   Ada Lovelace is considered the first computer programmer. Even though she wrote about a computer, the Analytical Engine, that was never built, she realized that the computer could follow a series of simple instructions, a program, to perform a complex calculation...

  Losing weight is not easy . . It takes dedication, motivation, and hard work. But you can make weight loss easier. But   there are easy tricks to lose weight. Changing what you eat is the first step.

Then start to build meals around healthy types of fish and poultry.  Eating lean protein helps to curb hunger so you eat less.  You should also make better choices at fast food...

    Hackers are criminals who gain unauthorized access to a network and devices, usually with the intent to steal sensitive data, such as financial information or company secrets. You can protect your computers by using firewalls and antivirus software and by following best practices for computer use.  You can protect your mobile devices by turning off Bluetooth when it's not in use, being mindful of the Wi-Fi networks you connect to and using security applications to improve monitoring and protectio.  A new threat known as computer hacking extended the definition of thievery to include infiltrating your computer, stealing personal information, tricking you into revealing private data, and using that data to steal and extort personal information, such as business secrets, bank account credentials and even people's identities.  Computer hackers are people who break into internet-connected devices such as computers, tablets and smartphones, usua...
