they create a 3D printed lens For $ 2

The application of 3D printing in medicine made ​​its way slowly. However, the recent creation ensuing could facilitate the work of physicians. It is a microscopic lens, when mounted on a terminal, acts dermatoscope functional. should this 3D printed researchers at the Australian National University lens. The concept is based on the optical effect caused by a drop of water. The team of Professor Steve Lee has managed to print 3D gel PMDS (a silicone polymer) on a glass slide. They were then baked at 70 ° C until it hardens. Repeating the action and adding a drop of the precious material, they managed to get a lens a few millimeters thick. Able to enlarge an image 160 times, its resolution is about 4 microns. Cost of operation: $ 2 according to its designers.

This invention can make medical microscopy everyone. With this inexpensive method, doctors can diagnose a patient with a smartphone or tablet to detect diseases of the skin.

In the prototype, its designers are trying to improve the process to create lenses printed in larger and powerful 3D.

Introduced Samsung Galaxy Ace Style

The South Korean technology company Samsung has introduced the Samsung Galaxy Ace style a new smartphone. The resolution of the four-inch display amounts to 800 * 480 pixels and on the back of the model a digital camera with 5 megapixels was installed. The front page features a VGA camera for video chats and phone calls. When CPU is a dual core processor was installed with 1.2 gigahertz clock frequency, and this is supported by 512 megabytes of RAM memory. The flash memory is 4 GB and can be expanded with a microSD card up to 64 gigabytes. The operating system, Samsung decided with Google Android 4.4 Kitkat for the latest version.

The communication standards WLAN, UMTS, Bluetooth and GPRS are supported. An NFC chip is for contactless payment via radio and available for mobile navigation is a GPS module ready. In Germany, the Samsung Galaxy Ace Style will be available for less than 200 euros in July. The entry-level smartphone is not as well equipped as the Samsung Galaxy Ace 3 because it does not provide 8GB of flash memory and 1GB of RAM. The launch will take place in other countries in April.

Apple opens beta of Mac OS X at all

While it was previously necessary to have a developer account to access the beta of Mac OS X , Apple has relaxed the rules and now allows anyone to use.

Named OS X Beta Seed Program , this new welcomes all types of registration and therefore no longer requires to perform the requested $ 100 to acquire a developer account. Once registered,participants will be able to get free test versions of Mac OS X , and so try to send a report to Apple allowing them to refine their system.

It is interesting to note that this decision comes just over a month before the WWDC 2014 will be held from 2 to 6 June in San Francisco, and a new version of Mac OS X could be presented.

Boxster and Cayman GTS GTS: Extra Power for Porsche's entry-level

In the growth market China celebrates Porsche AG, the world premiere of Boxster and Cayman GTS GTS. The double peak of the mid-engine sports of Porsche sets with 243 kw (330 hp) to 250 kW (340 hp) and a top acceleration sporty model in its segment.

The sporty appearance reflects a growing interest among Chinese customers top-class sports cars. The Roadster Porsche Boxster GTS makes  243 kW (330 hp) at 6700 1/min, the Coupe GTS Cayman stuck 250 kW (340 hp) at 7400 1/min under the hood. Where no speed limit bothers drives the Boxster GTS up to 281 km / h and the Cayman GTS 285 km / h The sprint from 0 to 100 km / h to succeed in the six-cylinder boxer engines in 4.9 to 5 seconds.

Consumption and prices

Consumption (each for 6-speed manual and 7-speed Porsche double-clutch gearbox) is the Boxster GTS intra-urban 12.7 to 11.4 l/100 km;extra urban 7.1 to 6.3 l/100 km; combined 9.0 to 8.2 l/100 km; the Cayman GTS intra-urban 12.7 to 11.4 l/100 km; extra urban 7.1 to 6.3 l/100 km. The new Boxster GTS is EUR 69949.00 from VAT, the new Cayman GTS is available from EUR 73757.00 incl.

Google is working on a project space elevator

According to a report by Fast Company, the Google X labs, working in secret on specific projects, have attempted to design a good orbital elevator to go into space.

Google X labs are a little hidden part of the iceberg google. far from the traditional activities of the Web giant, these labs are designed to perform operations research and development in all areas.   some of their projects been made ​​public, as automate cars or augmented reality glasses , others have leaked, as work on face recognition or voice recognition. The secrecy surrounding these laboratories will into their location, hardly do we know they are in the San Francisco Bay.

These secret laboratories would thus nurtured the ambition to build a space similar to that elevator recently referred by scientists at the International Academy of Astronautics. They had, however, referred to the difficulties of making such a project, and it seems that they are the same reasons that prompted Google to abandon the idea for the moment. The researchers include concluded that this would require "cables at least a hundred times stronger than steel more resistant than we know." If such a cable can be replaced by carbon nanotubes, the problem is in their design: for now,there is no cable carbon nanotube whose length exceeds the meter . The project has been shelved for now, but may well reappear soon as technological advances permit.

3D printing to create disposable UAVs

3D printing has the advantage of producing a real object in a relatively short period of time and "cost". Pushing the limits of this technology, engineers at the University of Sheffield have created a drone with the same print.

This 3D printed UAV is the work of the scientific research center of advanced manufacturing (CDMA). Taking the form of a flying wing, the prototype has been developed to best reduce the amount of materials needed for its construction. Thus, the unmanned craft 1.5 m wingspan was made from a Stratasys 3D printer using FDM technology. This extruded ABS plastic melt by depositing the layer by layer. In the end, the nine pieces that make up was created in less than 24 hours. For ease of transport, the apparatus can be disassembled into two. So this method opens the way to cheap and disposable but may also be able to fly over the sky drones.

For now, the prototype drone officiates as glider but its designers intend to equip a propeller propulsion system. A larger and more powerful model is also planned, carrying a GPS, an independent operating system and data recording.

Little Printer: The printer robot

Halfway between the printer and the robot vacuum cleaner, there is Little Printer , a project Kickstarter innovative but quite dispensable.

Little Printer is equipped with a motor and wheels that allow it to move, but simply on a flat surface.Mobile printer, simply place it on a sheet of paper to get to work. Compact design, it is against much slower than a conventional printer. It swallows an average of 10 pages per minute while the Little Printer will print in just over one in the same time. Also note that the print definition is far from being impeccable. At 96 x 192 dpi , it is really at the gadget. For now, it works with a Mac or PC. Mobile compatibility should be added shortly. Connect autonomy, its manufacturer announced that it is capable of printing 1000 pages with a single cartridge. By cons, nothing is said about the duration of the battery. Currently on Kickstarter , the project has already won nearly half of the funds necessary for its implementation. To obtain a copy of this robot-printer, it costs $ 180 (plus $ 20 shipping).
