Julius Richard Petri (May 31, 1852 – December 20, 1921) was a German bacteriologist who is generally credited with inventing the Petri dish while working as assistant to Robert Koch.
Petri first studied medicine at the Kaiser-Wilhelm-Academy for Military Physicians (1871–1875) and received his medical degree in 1876. He continued his studies at the Charité Hospital in Berlin and was on active duty as a military physician until 1882, continuing as a reservist.
From 1877 to 1879 he was assigned to the Imperial Health Office (German: Kaiserliches Gesundheitsamt) in Berlin, where he became an assistant to Robert Koch. On the advice of Angelina Hesse, the New York-born wife of another assistant, Walther Hesse, the Koch laboratory began to culture bacteria on agar plates. Petri then invented the standard culture dish, or Petri plate, and further developed the technique of agar culture to purify or clone bacterial colonies derived from single cells. This advance made it possible to rigorously identify the bacteria responsible for diseases.

We’ve been bringing readers news and leaks on the Samsung Galaxy Note 3, expected to be the next flagship device release for the giant manufacturer. This is due later this year, probably heading for a fall release and if you’ve been trying to keep up with all the rumors it can be difficult with so many sources. However we came across a short and sweet video summary of leaked & rumored specs, which also gives a look at various Galaxy Note 3 concept designs and we thought we’d share it with you. Along with this we’d like to know what would be the deal breaker for you on the next Galaxy Note?
While some of the rumors we’ve brought you are mentioned again on this video summary it’s convenient to have a shot of everything all at once. It’s also interesting to see some of the Galaxy Note 3 concept looks from designers and we wonder if any of the creations shown on the video are designs that you would like to see for the real deal?
The release date has not been confirmed but this video compiler mentions a September release, around the same time as the iphone 5Sis expected. As for specs, as a brief recap there have been rumblings of a 5.9-inch full HD Super AMOLED display, 13-megapixel camera, Octa-core processor, Mali 450 GPU, 3GB of RAM, and Android 4.3 or 5.0 Key Lime Pieskinned with TouchWiz.
A flexible display has been speculated many times but at this point it’s difficult to predict anything as far as this is concerned. A good point is raised at the conclusion of the video regarding whether, if these specs are accurate, consumers will find it worthwhile upgrading from the Galaxy Note 2 and we’d really like to hear from our readers regarding this.
Are you one of the many enthusiasts of the Galaxy Note 2 and are you considering upgrading to the Samsung Galaxy Note 3 when it appears? What for you would be a deal breaker on this? Please head back to us with your comments as we always appreciate views from our readers.

Microsoft has revealed its new Xbox, the successor to the Xbox 360. It’s a next-generation console, with plenty of power under the hood, but it’s also clearly about consolidating your digital entertainment and operate as much more of a lifestyle device.
“Where all of your entertainment comes alive in one place,” is how Microsoft’s Don Mattrick put it on stage during his introduction. The entire event was prefaced with a description of the various types of non-game media that’s becoming popular with online streaming set-top boxes and mobile devices. “To continue to lead, we must provide compelling answers to new questions,” Mattrick said.
“Design and build an all-in-one system to light up a new generation of games, TV and entertainment,” in a way that’s “simple, instant and complete” is how he characterized the mission for the new device.
VOICE CONTROL
Kinect is part of the package, and it’s a voice controlled experience from power on throughout the entire process. Your voice cues the Xbox to your user profile and sets up all your custom options. Then, you can dictate activities to Xbox One, sort of like how many imagined Apple would do their own Apple TV with Siri.
Changing between activities is as easy as telling the Xbox One exactly what you want it to be doing. It’s remarkably quick, quicker even than the process of changing channels on my at-home cable box hardware. But voice control isn’t the only trick, there’s also gesture recognition tech for controlling the system with your hands.
SNAP MODE
There’s a “Snap Mode” feature, too, which looks like the Microsoft Windows 8 experience, in that it allows you to run two activities simultaneously. So you can watch a movie and then also browse the Internet at the same time, for example, to look up elements of that film. You can even use Skype, newly introduced to Xbox with the Xbox One, and have that running in Snap Mode too.
The Snap Mode feature does something that has until now mostly been reserved for computers and for mobile and tablet devices: provides a second-screen experience that runs right alongside things like live TV. Adding basically a HUD layer to live TV might be the Xbox One’s biggest appeal for content providers who are looking for additional ways to engage audiences losing interest in traditional ads.
TECH DETAILS
The Xbox One has 8GB of RAM, along with a Blu-ray drive, as well as a native 64-bit architecture, a 500GB onboard hard drive, HDMI in and out (including passthrough capabilities for use with your existing home theatre setup), 802.11n Wi-Fi as well as an 8-core CPU and USB 3.0 connectivity. That’s mostly in line with what we’ve heard from previous rumors, but it’s still quite impressive.
The big advantage of the Xbox One is its architecture, however, according to Microsoft’s Marc Whitten. He said essentially it’s like they’ve combined three operating systems in one to deliver the seamless transition between games, applications, and live entertainment. The Xbox architecture combines with Windows, via a third OS that handles fast switching between multi-tasking apps.
KINECT AND CONTROLLER
The Kinect has been updated to capture 1080p video, as well as detect many more points on the body for more accurate recognition. It’s also better at recognizing voice input and gestures, and it can even read your heartbeat while you’re excercising.
Overall it seems like Microsoft has put a lot of effort into developing the new Kinect, in order to smooth out any rough edges that the launch device had in terms of working as naturally as possible.
The new controller looks like the one you know an dlove but has an integrated battery compartment (more like the PS Dual-Shock in terms of creating a slim profile on the back), as well as Wi-Fi Direct and a high precision D-Pad. The new trigger design is supposed to be much more powerful as well.
DVR, CLOUD GAME SAVES AND LIBRARY
New cloud-based features require that the Xbox One’s Live service has 15,000 servers backing it up, and offers a number of features like back up of your media content, games and game saves to the cloud for easy portability. There’s also a DVR function to record game play, and also share save states.
This is likely why the Xbox was said to require a constant Internet connection; it sounds like a lot of the functionality is based in the cloud. Microsoft has said that it doesn’t require the console to be “always on,” specifying that it will be designed to allow you to continue to watch Blu-rays, live TV and even play games should your connection drop.
THE ONE TO WATCH
When Sony unveiled their PlayStation 4, one of my complaints was that it focused too much on games and not enough on becoming more than just a console. Microsoft has taken the exact opposite approach, fielding a device that seems like it would be equally at home in either a hardcore gamer’s, or a non-player’s living room. That should help them deal with a changing gaming industry.
The Xbox One is launching globally “later this year,” but Microsoft didn’t get any more specific or provide an idea of price
The Samsung I9295 Galaxy S4 Active has been in our rumor mill for quite some time. The latest leaked shots reveal that the Active will be a tougher dust and water resistant version of the Galaxy S4 flagship.
The specs are expected to be the same and the live pictures below confirm it - the device is running on a quad-core 1.9GHz processor with Adreno 320 GPU, which most definitely means a Snapdragon 600 chipset. The screen supposedly has the same size and resolution as the original Galaxy S4 - a 5.0-inch 1080p unit, though it's unclear if it's a Super AMOLED one or not. Strangely enough, the reported pixel density of the phone is 480ppi, so the display might actually be smaller.
Our tipster also confirmed to us that the Samsung Galaxy S4 Active has an 8MP rear camera, which is a downgrade from the 13MP sensor of the Galaxy S4.
Samsung I9295 Galaxy S4 Active
Despite the similar specs, the Galaxy S4 Active looks nothing like the original. It comes in a metallic shell with bolts on the back, and there are also three hardware buttons below the screen.
There is no official info on the Galaxy S4 Active yet, but as it turns out the handset has been showcased recently in Croatia, so an announcement is imminent.
For casual tablet users or those already knee-deep in Amazon's digital media abyss, the Kindle Fire HD is a fantastic option, especially at the low entry price.
It offers a simple and uncomplicated experience through and through, and is built to support the digital media it aims to sell you, with an excellent screen (for a seven-incher) and surprisingly ample speakers.
Number 9: Asus FonePad
Quick verdict
The Asus FonePad is a very accomplished Android tablet and offers amazing value-for-money. If you're not planning on spending a fortune, but still want a tablet with a wide choice of apps and features then you could do a lot worse than picking up this one in particular.
Number 8: Samsung Galaxy Note 10.1
Quick verdict
Sure, it's a mite expensive, the screen quality is lower than we've seen from Samsung in the past and the build quality somewhat lower than the competition, but this is still a fabulous tablet that many workers constantly forced to use a paper and pen will love to try out.
Number 7: Microsoft Surface Pro
Quick verdict
It's a bulky device with significant weight, but at the end of the day you're pretty much getting a portable PC, and all that power means there's a wealth of options available on the Surface Pro which you just can't get on the more standard of tablets.
Number 6: Asus Transformer Pad Infinity
Quick verdict
Everything we'd look for in a high-end tablet is present and accounted for with the Transformer Pad Infinity.
While power is always welcomed, it was the improved screen that really caught our attention. Given that we use our tablet mostly for browsing the web and watching video, we couldn't help but marvel at the resolution, either. if you're looking for a top Android tablet (and have the cash to splash), then the Asus Transformer Pad Infinity should be at the top of your list.
Number 5: Samsung Galaxy Note 8.0
Quick verdict
The Galaxy Note 8.0 is a good device. There are better out there for the money, and with an arguably better design as well. However, for those that like the S Pen as a tool, it's a great offering, albeit not really worth the extra cash for most.
Number 4: Google Nexus 10
Quick verdict
The Google Nexus 10 is easily one of the best Android tablets on the market and while it's not quite as fantastic value for money as the Nexus 7, it certainly gives Apple's high-priced iPad 4 a run for its money. For the price you're paying, you won't be disappointed.
Number 3: iPad 4
Quick verdict
Dodgy name aside, the new iPad is the crème de la crème of the tablet market. The eye-popping Retina Display is something to behold, the vast array of tablet apps in the App Store is something Google Play can't touch, and the OS simply just works.
If your pockets are deep and your need is great, then the new iPad 4 is the tablet for you - and the tablet that all other 10-inch offerings are compared to.
Number 2: Google Nexus 7
Quick verdict
The Google Nexus 7 is the best budget Android tablet on the market. Nothing in its price range is able to touch it, although Apple has managed to have the last laugh with the iPad Mini.
If you're looking for a tablet which doesn't cost an arm or a leg, but provides enough power to act as an extra limb, then look no further – the Google Nexus 7 is the tablet for you, and the 32GB / 3G upgrade is enough to push it up into second spot.
Number 1: iPad mini
Quick verdict
"The iPad mini is the best iPad Apple has ever created" - need we say more? That's the official verdict from our in-depth review. If you have the extra cash to spend on the iPad mini over the likes of the Nexus 7 and Kindle Fire HD, you won't be disappointed.
The Nokia Lumia 925 is the second flagship phone Nokia has added to its Lumia lineup in a week. While the Lumia 925 shares many key specs with the Lumia 928 -- screen size, processor, and camera resolution -- it sports a metal design and, crucially, will be available outside of the U.S.
It's due to go on sale in the U.K., Europe, and China starting in June, with an estimated price of 470 euros before taxes -- expect that number to vary wildly once local taxes are applied.
Design Rumors have been circling for months now that Nokia has been toying with the idea of using metal in its phones. The chassis on which all the crucial components are mounted is metal, with thick metal banding present around the edges of the handset.
Rather than opt for an all-metal design though, the 925 has a poly-carbonate back plate. It's a shame not to see a single-piece metal construction. We've already seen this on the HTC One and iPhone 5, both of which are unquestionably stunning phones.
That's not to say the 925 doesn't look good though. Far from it. The metal edging feels firm and curves nicely to join the rounded edge of the screen. The back panel doesn't give much flex when you press on it, making it feel much more solid and secure than the plastic body of the Samsung Galaxy S4.
Display: The GSM radio supports 850/900/1800/1900 bands. There's also WCDMA support for 850/900/1900/2100, and LTE support for 800/900/1800/2100/2600 MHz.
The 925 packs a 4.5-inch display, which is physically the same size you'll get on both the 920 and 928. The 925 and 928 however use OLED screens, rather than standard LCD which promise richer colors and deeper black levels as they don't need to be back lit as do cheaper screens.
Nokia already has good form for squeezing vibrant screens into its phones though -- its "ClearBlack" technology on the 920 and other phones is excellent. In my demo with the 925, the screen certainly looked impressively bright and bold, but I was seeing it in a dimly lit office -- in those conditions, even a poor screen would shine like a supernova.
It has a resolution of 1280x768 pixels, which again is the same as you'll find on the 920 and 928. It's a shame not to see a push for a few more pixels -- it would help the 925 stand out as a clear flagship against its brothers -- but it did make the Windows Phone 8 interface look extremely crisp, so it would be wrong to suggest it's lacking pixels.
Camera Nokia has given the 925's camera a couple of small tweaks, too. It uses the same 8.7-megapixel sensor as its predecessor, but Nokia explained that it's improved the optics in front of the sensor. As well as the lightweight plastic lenses -- low weight is needed for the optical image stabilization -- the 925 uses a sixth glass lens which Nokia reckons gives better clarity, especially in daylight.
Nokia has also apparently improved its camera firmware to give better noise reduction in low-light situations. Until I can give the camera a thorough test, I can't comment on whether these tweaks are worthwhile. The Lumia 920 was already an excellent low-light performer, so let's hope Nokia hasn't messed around with that too much.
You will find some new camera software on board, chief among which is called SmartCam. This app (also integrated as a camera lens) takes a burst of 10 images that you can then edit into an action sequence, change the faces, or choose the best image from the bunch to save. We've seen these functions already on the HTC One and Samsung Galaxy S4. Unlike the Galaxy S4 though, you choose how to edit the images after you've taken them, rather than choose a setting to shoot in beforehand.
I've played around with the action sequence modes on other phones and found them to be a lot of fun -- so long as you have a particularly exciting scene to capture. Nokia's effort seems to work in much the same way, but with what seems to be a more stripped down, easier to use interface.
You can set the camera to automatically load in SmartCam mode, or you can pin the icon to your home screen to get access to it quickly.
One thing you will need to bear in mind though is that the Windows Phone 8 app store is still very understocked. You can find the odd jewel -- Netflix, Spotify, and Skype are all available -- but many big titles are missing, and WP8 devices are generally at the end of the queue for receiving new apps.
The 925 is powered by a 1.5GHz dual-core processor which -- surprise, surprise -- is the same engine that's inside the 920 and 928. It's easy to argue that Nokia needs to ramp up its processor if it wants to properly compete with the quad-core phones, but given that there's very little you can find in the Windows Phone store to tax a phone, it probably doesn't need to. I found swiping around the interface to be perfectly swift, but I'll reserve judgement for the final review.
Verdict:
With its new metal parts, the Nokia Lumia 925 is a sleek and attractive addition to the Windows Phone 8 range. Does it excite, though? No. It shares most of its key specs with the older Lumia 920 which doesn't really stack up well against the elite competition such as the HTC One and Samsung Galaxy S4.
We'll have to wait and see if the slight tweaks to the camera and the more sturdy build will make the 925 a serious smart phone contender.
