A Super Capacitor Capable Of Supplying Energy On One Time Charge

Scientists at the university Vanderbilt in Nashville, Tenn., have developed a super capacitor made of silicon. Once heretical idea, today the idea to take the form of silicon chip capacitor is not so crazy.

This capacitor would provide energy for a range of several weeks on a single charge, or build solar cells able to load with or without sun. Published in the journal Scientific Reports, the first super capacitor stores its silicon charge accumulating on the surface of a porous material.

A difference from the traditional batteries that operate in chemical reactions, the super capacitor can be charged in a few minutes while her discharge may last much longer. Silicon had been regarded as unsuitable for super capacitors because of its property but can react with the electrolytes that allow the storage of ions.

 “If you ask experts to make a super capacitor with silicon, you will get the answer that it is a crazy idea," says assistant professor Cary Pint, who leads the development team of Vanderbilt University. "But we can say is easy to do." Team Pint covered the silicon atoms, a very thin layer of a few nanometers of graphene, which stabilizes the silicon surface, perfect for storing the necessary load.

"Everything that defines us in modern world needs electricity," says Pint. “The more we can integrate the storage of electricity in existing materials and devices; they are more compact and efficient.”

Utilizing Miniature Surveillance Cameras

Surveillance cameras have come a long way in recent years.  They are now within financial reach of most homeowners.  With the advent of the internet, IP cameras, or internet protocol cameras, enable homeowners and business owners alike to have a surveillance system that is high tech, full of options, and reasonably priced.  The simplest system would be comprised of one mini video camera and an internet connection.  Of course, multiple cameras can be added when the owner desires.  Because the majority of homeowners and businesses usually have an internet connection, they only need to install a set of cameras to create a modern security system.  This can have applications for such as watching the entrance to a condo, observing customers by a cash register in a small business, or more discrete uses in either a business or a home.

Business Use of Small Surveillance Cameras

Profit is always the prime directive for a business.  Besides competing with other businesses, a number of factors can detract from a company’s bottom line.  Some of them are reasons a small business may want to install a digital surveillance system. These include worker’s compensation insurance abuse.   With enough cameras in place, a manager can verify what an employee was doing when he or she alleges that they were hurt on the job.  If there was an obvious injury, the process will go quickly, and the company can see exactly how it happened and try to alter safety procedures as appropriate.  If there was no injury, no money needs to be paid.  In the long run, both ways can save money for a company.   Another way to use IP cameras is to observe employee behavior.  A mini-video camera no bigger than a web cam can be placed unobtrusively in various locations in a facility.  These might include a building entrance, a staff lounge, above an assembly line, and so on.  Perpetual tardiness, employee efficiency, or financial impropriety may be observed this way, and personnel decisions can be made as necessary.  

Home Use of Discreet Surveillance

Homeowners, especially parents, may have many reasons to want a good security systems based on the use of IP cameras.  Parents can worry about their children in many different situations, and discretely placed cameras can help parents know what is going on even when they can’t be right there.  Cameras now come in many forms that don’t look like cameras, such as a faux smoke alarm, an AC adapter, or even a coat hook.  Children and visitors won’t know there is a camera, so they will act naturally.  If a teenager makes a bad choice with the liquor cabinet, or if teenage girl is home alone with a new boyfriend, the cameras can observe what transpires.  Across town, parents can check in via the wonders of the internet.  If the parents are out on the town, and they aren’t sure about the new babysitter, a hidden camera can tell them what is going on back at the house.  This can bring peace of mind to a worried parent.  Security from theft is another issue for homeowners.  Motion sensor cameras can be trained on entrances.  There is no need to sift through hours of blank screen.  When someone approaches the door, the camera comes on, and you can see it in high resolution images.  If a crime is committed, or even in there is suspicious activity, evidence will be apparent.

Google Chrome adds a function for automatic malware blocking

Google enhances the security of the browser by adding a feature that detects and blocks the download of malicious software. Google is soon going to introduce a new security feature in its Chrome browser. This is an automatic download of malware blocking.

Users will be notified by an alert message to be displayed at the bottom of the browser window. This feature is currently being tested in the developer version of "Canary” of Chrome. It will address the malware disguised as legitimate downloads that can modify browser settings or install adware.

"The wicked push you to install and run this kind of software by hiding in something you might want, such as a free screen saver, a video plug-in or, ironically, an update safety," explains Google. And in the Chrome version 29, it offers an option to restore the default settings in case of infection by malware.

Watson, the smartest IBM computer to diagnose the cancer better than medical students!

Watson is simply the smartest computer in the world. Designed by IBM; which is endowed with more artificial intelligence, that is capable of diagnosing cancers with a success rate higher than that of the medical students. It is a revolution in the medical world which is brought by Watson.

Its new mission is now to come and help doctors at Memorial Sloan -Kettering Cancer Center in New York, a center that has treated 1125 patients with a lung tumor in 2012. For this, a team of 25 researchers helped artificial intelligence to assimilate more than 600,000 medical data, primarily lung cancer.

The computer is now able, thanks to its ability to understand natural language, not computer language, to respond to questions from doctors and diagnose with a success rate of 90% of lung cancer! By downloading the patient record in the machine, Watson informs the doctor about the best treatment to use and displays a ranked list according to a confidence index decreasing.

Watson is currently undergoing testing in a New York hospital. Thanks to him, health care costs could be reduced by 30 % in the United States, either one, € 46 billion! The technology of artificial intelligence that is simply extraordinary and we hope it can help many people. In fact many are fascinated by this technological advancement but others prefer to rely on the advice of doctors.

Firefox 26 Beta Mozilla turns off all plugins

Mozilla is more serious in terms user security and hence Firefox 26 Beta disabled almost all plugins by default to protect users against their vulnerabilities and excessive resource consumption. But there is a prominent exception too.

With the beta version of Firefox 26; Mozilla announced a new feature namely click-to -play sharp: The browser no longer active with most plugins, such plugings must be activated by the user with only one click. Mozilla wants care more for the users and hence it increase more security of Firefox users, outdated plugins are one of the biggest malware gateways.

However, Mozilla makes a prominent exception for Adobe; hence Adobe Flash is not completely blocked. Flash content may be used on the web and so Flash will also used often hidden, click-to -play that would lead us to great confusion among users, argues Mozilla. However, there are restrictions for Flash and the Flash Outdated versions that are considered unsafe, are being blocked from Firefox click- to-play option and the user is prompted to install the latest version of Adobe Flash. Mozilla is working here claims to be closely with Adobe.

If a plugin is activated, the plugin for the entire site is unlocked so that users do not need to click unnecessarily often. The beta of Firefox 26 also comes with an advanced support for the H.264 video codec, which under Linux is now available on GStreamer. MP3 files can be played on Windows XP Firefox now, so under all Windows versions is now possible. The password manager of Firefox can handle the new version with password fields generated by scripts.

Updates of Firefox can also make if they do not have write access to the directory where Firefox in your computer, Windows users in the future. This planning in advance, however, that the Mozilla Maintenance Service is running on the respective computers. The introduced with HTML5 AppCache dissolved under Firefox 26 from no more questions, the users, and even if IndexedDB is used , which leads to no longer asking the user.

In terms of the browser supports CSS property "orientation”. Firefox no longer decodes an image that are not visible, to shorten the loading time of web pages. Also new is the app manager that installs HTML5 web apps on Smartphones with OS Firefox and the Firefox OS simulator and can debug. He replaced the simulator dashboard previously used for. Firefox 26 Beta is now available for Windows, Mac and Linux.
