iKnife Intelligent Scalpel detects cancer!

Always one of the most important and most daunting questions in cancer surgery is; Does the surgeon removes the tumor actually quite? Or maybe retarded but a few malignant cells? The iKnife is to eliminate these uncertainties quickly and correctly. The iKnife is an intelligent smart scalpel. During an operation in near real time, it determines whether the surgeon cuts in cancer or the normal tissue. The knife is a so-called electrocautery, - a standard tool of surgery that burns rather than cuts through tissue. "Since there is electro surgery to doctors complain about the smoke here," said Zoltan Takats from Imperial College London. Burned tissue is not only smelly, smoke also contains toxic substances. Modern appliances suck up the smoke. Zoltan Takats, who developed the iKnife responsible, recognized the unwelcome by-product of electro surgery diagnostic tool. "Our iKnife while also sucking the smoke but then we fish out our various ions and direct them into a mass spectrometer." There they are chemically treated. And feedback to the surgeon follows within seconds.

 That beats the usual method of analysis of suspicious tissue during surgery. The traditional histology with microscope can take more than 20 minutes but this iKinife do it within seconds. In the mass spectrometer hundreds of molecules are tested for their tissue distribution. "We are particularly important substances of the cell envelope. For examples fats or phospholipids, "says Zoltan Takats. The totality of the molecules results in a pattern, as a signature. The interpretation left to the researcher’s pattern recognition software. At the end of this process, a pattern is derived from the tissue intended. How do they discriminate the chemical patterns of healthy and diseased tissue, should be known first. The researchers tested the iKnife in the laboratory on 1624 cancer and 1309 healthy tissue samples from a total of 302 patients. And then they dare tentatively into the operating room. In 91 operations the iKnife was used in parallel to the traditional histological methods for the tissues intended. The result is astonishing histology goes with iKnife quite astounding 100 percent. "We were very surprised," says Jeremy Nicholson, head of the Department of Surgery and Cancer at Imperial College London. "When you reach 100 percent in some studies already?" He believes the identification of chemical patterns with the iKnife could be valuable far beyond the surgery also. "Perhaps the abnormal chemical signatures of smoke provide future targets for therapies. Because if you know how this biochemical change occurs, one might, however, can develop new drugs. " The first, sensational study of the team that developed the iKnife, turned Although procedures other to cancer, but the researchers have at least tested in the laboratory, such as the iKnife behaves in the tissue drying Berke other diseases. "We can distinguish the iKnife whether Crohn's disease or another inflammatory bowel disease is present," says Jeremy Nicholson.

 These traditional methods often fail, and it can take weeks months until patients are diagnosed correctly. However, the chemical signature of the smoke is clear and unambiguous. "If we unravel faster diagnoses, the patient is doing well. And also comes cheaper the health care, "says Jeremy Nicholson. With this argument, the researchers also justify the high price of iKnifes. The prototype cost 300,000 Euros. The researchers are currently preparing clinical trials with thousands of patients.

Intel confirms the Haswell chip with 4.5W SDP

In the previous IDF San Francisco, Intel promised: Haswell will go down to 4.5 watts of SDP. While the first models announced earlier during the launch failed to reach such figures, but internal documents evoked such product have just been confirmed. Haswell (Core Processors fourth generation) will be of only a few watts! If the information seems to surprise some, it is not really surprising. Intel had indeed indicated that there is nearly a year that the chip goes beyond Ivy Bridge. The latter was to 7 watts of SDP for some particular models, and 10 watts to TDP. The Atom and his successors, they are limited to about 2 watts in terms of the products currently covered by the mark in terms of mobility. In June, we already learned that the purpose was reached already down to 6 watts for 2-in-1 and the Ultrabook, warning that he did not intend to stop there. And it's now official; there will also be versions of 4.5 watts only SDP that will emerge during the second half of 2013. And they will "build the first 2-in-1 passive based on Core architecture." It remains to know the price of this product and its performance. These will necessarily be limited, especially as the SDP wants a realistic indicator of power consumption under conditions of use. Hopefully accessible products may be right and it is not only for mini-luxury machines.

New Smartphone LG G2

LG released little more details about the new G2 and promotes the presentation of the new Smartphones on 7 August 2013. According to a teaser video of the phone released by its owner it was learnt. According to another teaser video available here LG released more details about its new Smartphone. In the 1:37 minute film is hard to see anything more about the Smartphone, instead the audience learns a few interesting facts about the people: as long as it crawls, how many friends he has or how often he dreams. At the very end, the silhouette of a Smartphone, then the message "- LG G2 Learning from You" - appears, including the invitation, on 7 August to see how the G2 learns from its users.

 This suggests that LG has developed new software that recognizes the user and his typical behavior; it adjusts and adapts itself so that to simplify the usage of it. The rumors about the hardware equipment are 5.2-inch full-HD display and 800 Snapdragon processor - have now expanded to include a 13-megapixel camera, three gigabytes of RAM and an Adreno 330 graphics chip. LG makes an invitation to an event attracted attention in New York. A video also makes curious to 7th August 2013. A fairly clear indication of the performance of the LG G2 is the word "Great 2 Have You" - the G and the two are strikingly large. Not much is known yet about the new flagship. The alleged photos of the device surfaced on Twitter recently. Apparently those are stills from a promotional video. The Smartphone is named as G2 - the predecessor of it was called Optimus G. Inside the device might operate a 800 Snapdragon processor. Talking is also a 5.2-inch display with a resolution of 1920x1080 pixels.

Motorola Droid renews its range with three models

Combined with Verizon; Motorola this week unveiled the Droid Ultra Maxx and Mini. The first relies on the fineness of the design of its 5-inch display, while the Droid Maxx announced 48 hours of autonomy. The Droid is back with 3 new models, Motorola announced yesterday. First there is the Droid Ultra equipped with a 5-inch HD and a 10 megapixel sensor and displays a thickness of 7.2 millimeters. Then comes the Droid Maxx has the same 5-inch display, but that is all about self with supposed to provide 48 hours of battery power of 3500 mAh. The Droid Mini finally positioned on the waist with a 4.3-inch AMOLED screen. These Smartphones using a system on a chip X8 Mobile Computing System developed by Motorola. The SoC contains 8 cores with 4 dedicated graphics applications and is only used to manage the passive voice recognition system which is found in the Moto X also. This chip is based on the Qualcomm Krait architecture, but Motorola has not said by whom it is made. The three Smartphones will be available exclusively from Verizon from 20 August to $ 299 for the Droid Maxx, 199 dollars for the Droid Ultra and $ 99 for the Droid Mini with a two-year subscription. It remains unclear when these models will be available!

Windows 8.1 new patches available!

While Windows 8.1 will be officially released during the month of August, but in the mean time Microsoft continues to fix some bugs in the Public Preview. Thus, there are three patches that are currently deployed via Windows Update. They bring greater stability to SkyDrive and bug fixes for Internet Explorer 11 or the tethering function. The final version of Windows 8.1 is not expected until next month from Microsoft and certainly not before the fall in PC manufacturers meet. A Public Preview is available since the end of June and can give a good overview of the changes made by the Redmond over Windows 8, released last year. Still, the software giant is making adjustments in the Public Preview. A first one was made very recently, while three other patches are pushed for several hours. The first is to make it more stable SkyDrive storage service house online. The second patch seeks to solve a bug in Internet Explorer 11 when timer and VBScript code is used within a web page, according to specific scenarios. The third patch is meanwhile to improve the functioning of tethering, which made its debut with Windows 8.1, and that did not work as expected. As a reminder, it allows you to share an Internet connection if a 3G / 4G modem is present in the device.
