U.S. scientists have developed a syringe, injection drug use without a needle.
The results of Professor Ian Hunter and his colleagues at the Massachusetts Institute of Technology published in the Journal of Medical Engineering & Physics. effect devices based on the force with which the electromagnetic field acts on a point charged particle - the Lorentz force. Inside the syringe is a powerful magnet of small size, surrounded by a wire coil. In turn, the piston is attached to the coil, part of which is located inside the vials of medicine. Under the influence of the current coil drives the piston, "throws" of the drug vials at a rate of 314 meters per second - nearly the speed of sound. The jet of fluid from the mosquito's proboscis width "penetrates" the skin and delivers the drug into the tissue to the desired depth. In order to facilitate the adsorption of the drug, the flow velocity after penetration into the skin is reduced. Change the speed and pressure of the fluid, as well as the depth of penetration of drugs is possible by means of the current. The authors develop point out that a wide range of adjustable parameters makes it possible to inject even through the eardrum. "For the injection a child does not require the same high-pressure fluid, as an adult. When you use our device can be varied pressure, and this is its main advantage, "- quoted in the report the words of one of the sponsors of the development of Katherine Hogan. Now, scientists plan to create a new version of the syringe, with which, as injections may be injected powder preparations. researchers believe that new development will be useful not only for patients who for various reasons, are afraid of injections, but also employees of medical institutions. According to the Centers for Disease Control and Prevention USA, 385 000 hospital staff once a year suffer from accidental puncture needles.

Social network called Budist.ru (from the word to awaken), established Hrachik Adzhamyanom, earned already and the Ukraine.
As the founder of the social network said, in the service strangers anonymously and free of charge to help each other to wake up in the morning, calling on the phone and wanting a good day. idea of this service, which has no analogues in the world, came to mind is the millions of Russians. On June 4, 2012 service was made available not only in Russia but throughout the world. Adzhamyan Rook also said that calls to the service is absolutely free, and phone numbers of complete anonymity. According to him, all Russian-speaking users can register and become a "Sonia" (one who wakes up from calls of other people) or "Budistom" (one who wakes up strangers). The project is now "Budist" began to be translated into other languages, which will wake the people in other countries."Members of social alarm draws completely anonymous and the effect of uncertainty - you never know from what city, and who you will wake up. And now - and from what country, "- says the creator of the service. Notice social network has also released an application Budist for iPhone and Android.

Cockroaches and geckos use their body as a pendulum for a kind of flips when jumping from one branch of the tree on its opposite side. This helps them to become "invisible" and escape from predators, according to American biologists.
A new study by scientists dedicated to the commission of a seemingly impossible maneuvers that allow insects to escape unnoticed or reach his victim. Thus, geckos and cockroaches have the ability to quickly jump to the opposite side of the branches, boards, or any other bulky items in the event of a threat to life. behavior of cockroaches, acrobats studied a group of biologists and engineers led by Jean-Michel Mongo at the University of California at Berkeley, USA. " When viewed from the side it was quite clear what was happening, but we took this process on a high-speed camera and slowed down the video, we were struck by the fact that cockroaches use their hind legs to grab the surface and the upheaval in the opposite direction, "- said Mongo. According to researchers, cockroaches use his body as a kind of pendulum, which are the thread of an insect leg.

According to researchers, cockroaches use his body as a kind of pendulum, which are the thread of an insect leg.
Mayatnikopodobnoe motion during the jump can reach the opposite side of the branch or the board, without slowing down their movement and using the momentum to somersault. In this movement the insects feel sufficiently high overload. Scientists have calculated that in the cockroach effect acceleration force 3,8 G, which can be compared with the loads experienced by astronauts during takeoff or landing shuttles. unravel the secret of the cockroaches, the researchers conducted a similar experiment with the gecko. It turned out that geckos use exactly the same mechanism for making the jump to the other side plates. To attach the end of the branches of geckos use claws and special sticky hairs on their hind legs. Engineers used the data to create a robot DASH, simulating the movement of geckos and cockroaches. As a substitute for the claws on the legs and cockroach sticky hairs on gecko feet, scientists have used Velcro fasteners, half of which they are attached to the feet of work and stuck on both sides of the plates. This design allowed the job successfully jump from one side of the board to another and keep going.Mongo and his colleagues believe that their work will help create robots that can overcome any obstacles as well as animals. "To date, some robots are good at running or climbing, but there are few machines can simultaneously do both, or to quickly switch between modes of motion. This is the main objective of the current robotics - the development of robots that can move in a geometrically complex surface and wade into dangerous areas, where the manager can not get them people "- concludes a member of the group, Robert Full.

Best Browsers All The Time

Best Browsers All Time
Chrome
Windows only (for practical purposes, but soon on Mac and Linux, if we're lucky): Some browsers have roots going back to the early 1990s—Chrome, on the other hand, is the new kid on the block. Although Chrome has a distant relationship to Konqueror and is a cousin to the Safari web browser—both share the speedy WebKit rendering engine—Google's browser is less than a year old. Despite its youth, it's already garnered praise for its minimalist interface and snappy page rendering. Chrome also handles site errors and quirks well, and each individual tab is a unique process, so a crash or lag in one shouldn't pull down or crash the others. In general, though, Chrome has caught attention for running a performance-focused JavaScript engine in a lightweight GUI. Also worth noting, Chrome has been holding its own in the recent Pwn2Own security challenge, with the distinction of being the only browser left standing after the first day of security exploits and attacks.Opera
Windows/Mac/Linux: Opera is a rock-solid browser with roots stretching back to 1994. Many of the features baked right into Opera are either not implemented in other browsers, or require multiple extensions at the cost of system resources—navigation by mouse gestures is one of the flashier examples. Despite being feature-packed, Opera has a fairly small market share, due largely in part to being trialware up until 2000 and advertisement-supported until 2005—many people were turned off by the expense, if not the ads. Still, Opera proponents have long claimed that Opera beats Internet Explorer and Firefox when it comes to speedy rendering. Another selling point for Opera is the quality of the built-in tools. For many users, the built-in RSS reader, email client, and BitTorrent client do their jobs admirably, cutting down on the number applications they need running at once. Opera is extensible, but the pool of available extensions is radically smaller than that available for Firefox.Firefox
Windows/Mac/Linux: Firefox is the grandchild of the venerable Mosaic browser and free-roaming son of Netscape. Although Firefox has a myriad of user-friendly, forward-thinking features, a decently secure framework, and an open-source ideology, its most prominent is extensibility. When convincing a Firefox user to abandon Firefox for anything else, even temporarily, you won't have to fight them over giving up the AwesomeBar or about:config tweaks—you'll hear a common, understandable refrain: "What about my extensions?" The repository of extensions maintained by Mozilla currently has over 6,000 entries, covering everything from blocking advertisements, to managing your clipboard, to allowing you to further customize your browsing experience with scripts a la Greasemonkey (here's 10 of our must-have picks). Combine the passion people have for extensions and the ability to sync those extensions across multiple computers and portable installations, and you've got a force to be contended with. For a closer look at Firefox, make sure to check out our power user's guide to Firefox 3 and the top 10 Firefox 3 features.Internet Explorer
Windows only: Internet Explorer still commands a healthy chunk of the browser market, mostly because it ships with the most popular operating system on Earth and fits, if not exactly elegantly, into corporate computer plans. While many or most IE users stick with it for lack of wanting to try something else, Lifehacker readers definitely don't fall into that crowd—the majority of readers who voted in favor of Internet Explorer are sporting Internet Explorer 8. By contrast, nearly 20 percent of those surfing the web right now are using Internet Explorer 6, which had its initial release in 2001. Version 8 could mark a resurgence for the brand, though. It's the first version of Internet Explorer to have a strong focus on web standards compliance, as well as increasing rendering speed. And like Chrome, Internet Explorer 8 maintains a separate process for each tab to increase stability and security. Internet Explorer 8 has also beefed up its security measures from previous versions, including active filtering against malicious cross-site scripting and ActiveX isolation from the core of the browser.Safari
Windows/Mac: Safari is Apple's contribution to the web browsing world, built originally to fit snugly inside OS X. Like Chrome, Safari runs the speedy WebKit rendering engine for snappy page loads. In addition to its WebKit core, Safari also has the Nitro JavaScript engine, which lays claim to radically faster JavaScript execution than Internet Explorer and Firefox (in its own testing reports, anyways). Safari sports Apple's Cover Flow browser for perusing your history and bookmarks and an eye-catching display of the top 24 sites you've visited as the default page when Safari is loaded.Engine In Town - Google Vs Bing

Google Stand Aside – There’s A New Engine In Town
Given Google’s
supremacy, who would ever have thought that there would be any
competition in the Internet search business? Most of us would bet the
farm that would never happen. But wait, hold your bets, because there is
a new engine in online who is giving Google employees a major headache.
Welcome the brand new search engine owned by Microsoft named: “bing”.
So what makes bing a competitor that can stand up against Google?The answer is quite simple:
* “Searchers can choose the best scope for their search query
* Bing can provide best match and useful links and information
* Quick Preview of any website
* Bing can provide Instant Answers
* Bing will Auto-Suggest the search queries” (toputop.com).
* Bing can provide best match and useful links and information
* Quick Preview of any website
* Bing can provide Instant Answers
* Bing will Auto-Suggest the search queries” (toputop.com).
Soon, many of us will do our searching using bing for everything from
travel, to shopping, and targeted researches. The main reason to switch
to bing is you retrieve accurate and related websites in your search,
rather the clutter that Google is now producing in their first five or
ten listings. Google is gathering too many junk results for search
requests. In that regard, I believe, as many others do, bing will put a
serious dent into Google’s dominance in the world of search.
Is Google scared?
You bet. The New York Post says.
“You’d think nothing would get under the skin of search giant Google.
But co-founder Sergey Brin is so rattled by the launch of Microsoft’s
rival search engine that he has assembled a team of top engineers to
work on urgent upgrades to his Web service”.
Great praise for this new search engine is pouring in as INFORMATIONWEEK
reports, “Bing includes features that allow users to book travel and
engage in other e-commerce transactions with just a few clicks.”
To get a real taste of bing watch this VIDEO. It demonstrates the
accurate search results that are more targeted results as Google
squirms: http://tinyurl.com/mrsjum
One must admit, “bing” is kind of a wimpy name, but hey, what about the name Google?
One must admit, “bing” is kind of a wimpy name, but hey, what about the name Google?
“Back in the day”, or so they say, I remember when nobody used Google
because it was a strange name. There was another strange named search
engine along when Google started up named: “Dog Pile”.
Dog pile never made the big time as Google certainly did and it never
became a household phrase like “Google it”. However, “Dogpile search
engine earned the 2006 and 2007 J.D. Power and Associates award for best
Residential Online Search Engine Service”, according toWikipedia.com.
This new engine in town is a “must” to test drive.

The ribbon UI has transformed way in which Menu and Menu Items are arranged and presented in Microsoft Windows.
In windows 7 the WordPad and Paint comes with ribbon UI, but not in very useful Notepad application.I came across the Notepad 7 which has the well accepted ribbon UI for menu and menu items. Its developed by sky4u team. Notepad 7 is very much like Microsoft Notepad, with MS Office 2007 and 2010 Look and Feel, and with same functionality as Microsoft Notepad.
The Notepad-7 works well on Microsoft Windows Vista Service Pack 2 and Microsoft Windows 7 and it is necessary to have Microsoft .Net Framework 4.0 installed.
