Scientists have created the world’s first practical artificial leaf that can turn sunlight and water into energy, which they claim could pave the way for a cheaper source of power.
A team at Massachusetts Institute of Technology (MIT) says that the artificial leaf from silicon, electronics and various catalysts which spur chemical reactions within the device, can use sunlight to break water into hydrogen and oxygen which can then be used to create electricity in a separate fuel cell.
“A practical artificial leaf has been one of the Holy Grails of science for decades. We believe we have done it. And placed in a gallon of water and left in sun, these artificial leaves could provide a home in the developing world with basic electricity for a day,” Daniel Nocera, who led the team, said.
He added: “Our goal is to make each home its own power station. One can envision villages in India and Africa not long from now purchasing an affordable basic power system based on this technology.”
Both teams produced devices that combine a standard silicon solar cell with a catalyst developed three years ago by professor Daniel Nocera. When submerged in water and exposed to sunlight, the devices cause bubbles of oxygen to separate out of the water.
The next step to producing a full, usable artificial leaf, explains Nocera, the Henry Dreyfus Professor of Energy and professor of chemistry, will be to integrate the final ingredient: an additional catalyst to bubble out the water’s hydrogen atoms. In the current devices, hydrogen atoms are simply dissociated into the solution as loose protons and electrons. If a catalyst could produce fully formed hydrogen molecules (H2), the molecules could be used to generate electricity or to make fuel for vehicles. Realization of that step, Nocera says, will be the subject of a forthcoming paper.
The reports by the two teams were published in the journals Energy & Environmental Science on May 12, and the Proceedings of the National Academy of Sciences on June 6. Nocera encouraged two different teams to work on the project so that each could bring their special expertise to addressing the problem, and says the fact that both succeeded “speaks to the versatility of the catalyst system.”
Nocera’s ultimate goal is to produce an “artificial leaf” so simple and so inexpensive that it could be made widely available to the billions of people in the world who lack access to adequate, reliable sources of electricity. What’s needed to accomplish that, in addition to stepping up the voltage, is the addition of a second catalyst material to the other side of the silicon cell, Nocera says.
The “leaf” system, by contrast, is “still a science project,” Nocera says. “We haven’t even gotten to what I would call an engineering design.” He hopes, however, that the artificial leaf could become a reality within three years.

IPv6
As IPv6 is around the corner and set to grow in the coming few years, are you ready for it yet?
Find out using this test if your network are ready for IPv6.
IPv6 is an IP address standard designed to replace the current IPv4 protocol, which has been in use since the 1980s for routing Internet traffic. The new protocol has been available for several years now and supports several magnitudes more address spaces than IPv4, while also providing better security and reliability.
For more than 30 years, 32-bit addresses have served us well,but the growth of the Internet has mandated a need for more addresses than is possible with IPv4. IPv6 allows for vastly more addresses. IPv6 is the only long-term solution, it has not yet been widely deployed. With IPv4 addresses expected to run out in 2011, only 0.2% of Internet users have native IPv6 connectivity.
While IPv4 allows 32 bits for an Internet Protocol address, and can therefore support 232 (4,294,967,296) addresses, IPv6 uses 128-bit addresses, so the new address space supports 2128 (approximately 340 undecillion or 3.4×1038) addresses. This expansion allows for many more devices and users on the internet as well as extra flexibility in allocating addresses and efficiency for routing traffic. It also eliminates the primary need for network address translation (NAT), which gained widespread deployment as an effort to alleviate IPv4 address exhaustion.
On 8 June, 2011, top websites and Internet service providers around the world, including Google, Facebook, Yahoo!, Akamai and Limelight Networks joined together with more than 1000 other participating websites in World IPv6 Day for a successful global-scale trial of the new Internet Protocol, IPv6. By providing a coordinated 24-hour “test flight”, the event helped demonstrate that major websites around the world are well-positioned for the move to a global IPv6-enabled Internet, enabling its continued exponential growth.
Organised by the Internet Society, the project was intended to raise awareness about the need to start the global transition to IPv6 and to enable participants to gather data about potential glitches.
Many of the problems are likely to stem from the simple facts that IPv6 is far newer and untested technology compared with IPv4, and that the two protocols will need to coexist for several years.
The real test of the IPv6 protocol, however, will come when companies start migrating to it in earnest in the next few years.

GOOGLE VOICE SEARCH
“Most awesomest Google search feature ever.”
If your vocalized search gets you the resulting links, it means you already have the answer. But chances are you don’t as it was only this past Tuesday that Googleannounced their voice-recognition technology for desktops. Add to that the two other snazzy features Google’s integrating into its search engine and you’ve got a three-pronged approach to bolstering what’s already the world’s most popular internet search tool.
The first of the features will enable users to search the web simply by speaking their requests. Called Voice Search, the speech-to-text application will be activated by clicking on a microphone icon located next to Google’s query box. Voice Search has already gone mobile as an App for Android phones, but Google wants to enable its users to search via speech recognition on their laptops and desktops as well. In addition to the convenience of not having to type, Voice Search will be a helping hand in those hard-to-spell searches. It’ll also be easier to, as Google puts it, enter “long queries, even really, really long queries, just by talking.” Initially, Voice Search will only be available on Chrome browsers, but they plan to make it compatible with other browsers in the future.
Not only is Voice Search already being used on Android phones to search, it’s also enablingvoice command control of applications. In the time since Android adopted the App in 2009 Google has built a voice-activated search database of more than 230 billion words spoken by users. The database was used to hone Voice Search’s speech-recognition capabilities. Not only does the program learn how people pronounce words but it also learned what phrases people commonly used in their queries. For now Voice Search only understands English, but Google plans to eventually add more languages.
The video below includes a short demonstration. If you don’t have Chrome, download it today and wait for the little microphone icon to appear next to the search window–you’ll need a mic too, of course. But if fellow Hub writer Aaron’s experience with Google Translate is any indication, we may find ourselves wanting to kill the guy in the next cubicle over who keeps yelling at his computer, “Cirque Du Soleil tickets…Du Soleil…DU-SO-LEIL!”
Assuming it works the way it’s supposed to, Voice Search will certainly make our searching that much easier. But Google knows that a picture is worth a thousand words, which is why they’ve also launched a feature called Search by Image. The desktop version of Google Goggles that have been on mobile devices since 2009, Search by Image allows you to query with digital pictures. If you haven’t seen it already, check it out by going to images.google.com and clicking on the camera icon next to the search box. You can drag and drop, upload an image from your drive, or cut and paste an image’s URL. It’s a great idea and, hey, for completeness Google should be able to search images, right? I tried it out with a few images. It was pretty much as if I’d typed in “komodo dragon,” except many of the resulting links contained the image I’d used. The results are actually broken up into “Pages that include matching images” and “Visually similar images.” Google encourages users to plug in vacation photos and see if Search by Image can recognize where you’ve been. Pretty awesomely, when I tried it, Google nailed Paris’s Gare de Lyon, even though mine wasn’t a particularly good photo. It got the Eiffel Tower too, but that seems easy to me. However it mistook the Greek island of Santorini for jets of all things–maybe too much silhouette. And apparently I don’t have a single distinguishing feature on my face. A picture of me returned pretty much any and all men, women, and children of all shapes and sizes with pictures on the internet. Actually, the image-recognition technology can recognize faces, but for privacy purposes Google has thus far decided to disable that capability.
With Voice Search and Search by Image, Google has made the user search more versatile and, potentially, more convenient. To compliment these improvements, the last goodie in their bag of tricks improves the way Google returns their results. You think Google’s fast now? You ain’t seen nothin’ yet. The search giant’s new Instant Pages will bring you results–much of the time–instantaneously. As you type, the Instant Pages feature predicts what sites you’re most likely to be looking for and begins loading the web pages before you’ve even clicked on the link. If it’s right, the page essentially loads instantaneously, saving users two to five seconds per link clicked, according to Google. Check out the side-by-side speed test in this video.
The technology that gives Instant Pages its speed is called prerendering. Whatever web page it thinks you want, “the browser fetches all of the sub-resources and does all of the work necessary to display the page.” Often, the user won’t even notice a loading time. The prerendering technology is not Google’s alone, it’s available for use on other sites. But Google’s unique capability to predict what site the user is searching for means Instant Pages won’t spend its time queueing up the wrong pages which could lead to slower loading times for the link the user does actually click. Google is offering third party services to sites that use or might want to adopt prerendering. There’s a sample page on the Chromium blog where interested parties can test drive Google-powered prerendering for their own pages. Chrome even has a new experimental page visibility API that developers can access to determine the “visibility status of their page: whether it’s in a foreground tab, a background tab, or being prerendered.”
For most of us, three to five seconds per click isn’t going to make much of difference in our daily schedules. The main goal behind Instant Pages is not to increase user efficiency but to make web searching a more rewarding overall experience. Making the search experience more enjoyable is consistent with Google’s mission of “Knocking down barriers to knowledge.” Frustration is distracting. Faster searching makes for a happier–and more focused–user.
But I wonder how long it’ll take for the novelty of speaking our searches, or searching images, or retrieving pages in the blink of an eye will last. Pretty soon we’ll be yawning and asking, “What else ya got?”
Whatever it is, my bet is that Google’s already working on it.
In case you haven’t seen enough footage of Google’s new features, the following is a video of Tuesday’s media event in which they were unveiled.

google plus social networking.
Waiting for a Google Plus invite? Google is rolling out the service in waves and you can expect it to become a ubiquitous social option in the coming months. We have been playing with the service since getting invites yesterday and there are a lot of things to like about Google's new social initiative. Unlike Google's last big invite-only rollout of a social initiative - Google Wave - users will not be confounded on just what the heck you are supposed to with the service when signing up for the first time. From Friendster, Friendfeed, MySpace and Facebook, users are familiar with how a social platform is theoretically supposed to look. At its core level, Plus is not that much different. Yet, there is so much more. How do you get started with Google Plus? Let's break down the nuts and bolts.
From the initial interface, you will see four buttons - Home, Photos, Profile and Circles.
The first thing you are going to want to do is set up your circles. Click on the tab and it will bring you to a interface where all of your contacts in Gmail (not just Gmail addresses, but all of your contacts) are listed in a panel on top of the screen. Below is a panel that has your various circles. To add a contact to a circle, drag from the top of the list to the appropriate group. Contacts can be added to multiple circles.
One of the initial problems I had from the circles interface was that I added a couple of "Friends" into my "Work" circle and could not figure out how to get them out. You can do this from the user streams by hovering over the person's name and hovering over "Add to circles" and clicking the appropriate boxes. Yet, from the circles interface, that was not readily apparent. To take people out of a circle, hover above the circle, grab their icon and drag it back into the people plane.
One of the great differentiators between Twitter and Facebook is the "unbalanced" or "balanced" follow. Facebook was initially a two-way follow paradigm - I friend you, you friend me and we see each other's updates. This has been changed with the ability to "like" groups, brands and pages without them following you back. Twitter has always been a one-way follow - I follow you and you do not necessarily have to follow me back.
This line has been blurred in circles. If a person is in your contacts, they can be added to a circle and will get a notification that has happend (but not what circle they have actually been added to). There is also a "follow" circle. Just like Twitter, you can follow people and see their updates without them having to follow you back. As your circles evolve this could allow to track different interests, like Twitter lists.
There are two other options below your circles - Incoming and Notifications. Clicking incoming will bring you to messages that have been sent by people outside of your circles. Notifications will show you when people in your circles have commented on something you have posted, or something you have commented on.
Below the circles and notifications there is a tab dubbed "Sparks." More on that below.
One of the killer features of Gmail, or any Google product, is Chat. It has made its way into Plus and sits in the familiar left-hand, bottom-right portion of the screen that it is found in Gmail. Users with a lot of Circle and Chat contacts will like the ability to enable chat for particular groups. Want to surface friends and family but not acquaintances? Plus will let you do that.
If you are using Plus in a Chrome browser, desktop notifications do not pop up when someone sends you a message like it would in Gmail.
Posting a status update in Plus is not like sending a Tweet or updating Facebook. The core functions of an update are present - photos, links, video and location - but when you hit "share" it doesn't automatically post your message to everybody in your circles. You have the option to decide which circles your update is posted to, from individual groups to all circles, to extended circles, or just a single person.
An interesting feature in the user stream is that conversations will surface back to the top of the feed when subsequent comments are made on a thread. This, according to Google developer Jean-Baptiste Queru, is called "bumping." Google Buzz has this same capability and it was also a feature of FriendFeed.
When you add a photo, it will prompt you to create an album. Once that album is created it will ask which of your circles you would like to share it with. This is a prime differentiator from Facebook where all of your photos are visible to all of your friends by default (you can change who can view certain photos in Facebook preferences). You can also pick an individual to share photos with instead of an entire circle.
Photo uploading is easy within Plus. Just like adding a picture or an attachment to a Gmail document, you can drag-and-drop from your desktop or click the on the upload button and browse your computer for pictures.
Users can also add photos by posting them in status updates or by uploading them through the Profile tab.
Your Google Profile is now the hub of you Plus experience, the backbone that everything else is built upon. There are six tabs in your profile page - posts, about, photos, videos, +1s and Buzz.
A significant change to your profile page is that there is now a location where your +1s live. Until now, when you clicked +1 on content on the Web, nothing happened. The information was sent to Google and integrated into some type of esoteric search algorithm. Users can now see what people have +1ed through their Google Profile. Unlike the Facebook share/like/recommend buttons, it does not go straight into your stream but rather to the profile page.
Sparks is the part of Plus where you can find content on the Web that you are interested in. In the "Field Trial" version of Plus, it looks like Sparks is a randomized version of content and news generated through Google News. Sparks can be a dashboard for things you are interested in on the Web. When you do a search in Sparks, it will predict what you are searching for with a drop down menu (like old Google search, not quite like Google Instant). You can pin particular topics you search for to the Sparks dashboard for quick access.
You can share articles found in Sparks with a share button on the bottom of every article that surfaces in a search. Like everything else in Plus, it can be shared with a specific person, circle, group of circles or the general public.
Create Your Circles
Imagine the ability to break down Facebook into its various constituent parts and keep them separate from each other as opposed to one giant feed. That is what Google has done with Plus. There is one main stream where all your friends updates show up then the option to see updates from only certain groups like "Work," "Friends" or "Family." This is the essence of Circles.From the initial interface, you will see four buttons - Home, Photos, Profile and Circles.
The first thing you are going to want to do is set up your circles. Click on the tab and it will bring you to a interface where all of your contacts in Gmail (not just Gmail addresses, but all of your contacts) are listed in a panel on top of the screen.

The Stream and "Bumping"
Once you have set up your circles, go back to the Home screen to see the results. Below the profile picture you will see the choices of stream. You can view your entire stream at once (à la Facebook) or by particular circle.There are two other options below your circles - Incoming and Notifications. Clicking incoming will bring you to messages that have been sent by people outside of your circles. Notifications will show you when people in your circles have commented on something you have posted, or something you have commented on.
Below the circles and notifications there is a tab dubbed "Sparks." More on that below.

This, according to Google developer Jean-Baptiste Queru, is called "bumping." Google Buzz has this same capability and it was also a feature of FriendFeed.
Photos
Photos in Plus are relatively self-explanatory. Users can update photos from their computers or from their phones, see photos that people in their circles have uploaded. With the Android app, there is a way to upload any photo that you take with your phone straight to Plus, an interesting if slightly disconcerting feature.When you add a photo, it will prompt you to create an album. Once that album is created it will ask which of your circles you would like to share it with. This is a prime differentiator from Facebook where all of your photos are visible to all of your friends by default (you can change who can view certain photos in Facebook preferences). You can also pick an individual to share photos with instead of an entire circle.

Users can also add photos by posting them in status updates or by uploading them through the Profile tab.
Profile
If you use any Google products and have a Google account, you have a Google Profile. Profiles are unknown to most of the Internet because, until now, it was relatively useless to anyone but Google.Your Google Profile is now the hub of you Plus experience, the backbone that everything else is built upon. There are six tabs in your profile page - posts, about, photos, videos, +1s and Buzz.
A significant change to your profile page is that there is now a location where your +1s live. Until now, when you clicked +1 on content on the Web, nothing happened. The information was sent to Google and integrated into some type of esoteric search algorithm. Users can now see what people have +1ed through their Google Profile. Unlike the Facebook share/like/recommend buttons, it does not go straight into your stream but rather to the profile page.
Sparks and Hangouts
Hangouts is a new feature rolled out with Plus. Essentially it is an area where your circles or a select group of friends can video chat all on one screen. To start a Hangout, go to the "Welcome" button in the home tab. It will prompt you to start a hangout and invite individuals or entire circles. Up to 10 people can be in a hangout at once and it will be seen in that circle or users' stream.Sparks is the part of Plus where you can find content on the Web that you are interested in. In the "Field Trial" version of Plus, it looks like Sparks is a randomized version of content and news generated through Google News. Sparks can be a dashboard for things you are interested in on the Web. When you do a search in Sparks, it will predict what you are searching for with a drop down menu (like old Google search, not quite like Google Instant). You can pin particular topics you search for to the Sparks dashboard for quick access.
You can share articles found in Sparks with a share button on the bottom of every article that surfaces in a search. Like everything else in Plus, it can be shared with a specific person, circle, group of circles or the general public.
