Artificial blood created from stem cells could be tested on Britons within  two years.
The scientists behind the research, which could provide industrial scale quantities of blood, believe it will transform transfusions by preventing hospital shortages, and save thousands of lives on battlefields and at the scene of car crashes.
Heart transplant, bypass and cancer patients would also benefit from having a guaranteed supply of blood on hand for their surgery.

The ‘holy grail’ of blood research, the man-made blood would be free of infections that have blighted natural supplies and could be given to almost everyone regardless of   blood group.
The hope comes from Edinburgh and Bristol university researchers who have, for the first time, made thousands of millions of red blood cells from stem cells – ‘master cells’ seen as a repair kit for the body – taken from bone marrow. But with the average blood transfusion containing 2.5million million red blood cells, this is not enough.
Cells taken from human embryos in the first days of life are easier to multiply in large numbers, but the researchers have so far not managed to make such realistic blood.
If they crack the recipe, just one embryo could theoretically provide all the cells ever needed for Britain’s blood supply.
Edinburgh University’s Professor Marc Turner hopes to make a supply of cells with the O-negative blood type. This ‘universal donor’ blood could be given to up to 98 per cent of the population.
A supply of safe blood would also be a boon in developing countries, where thousands of lives are lost   to conditions such as haemorrhages after childbirth. Mr Turner predicts that in two to three years, he will be ready to inject a teaspoon of man-made blood into healthy volunteers, in the first British trial of blood from stem cells.
Large-scale trials would follow, but the blood could be in routine use in a decade. Within 20 years, it may be possible to produce two million pints of artificial blood a year – enough to satisfy the nation’s medical needs. Any embryonic stem cells used would be taken from four or five-day-old embryos left over from IVF treatment and donated to the research project.

Critics say it is wrong to plunder an unborn child for ‘spare parts’ to advance medical science.
But Mr Turner, who is funded by the Wellcome Trust, said: ‘There is a lot of regulatory framework to ensure that the cells are being treated with the appropriate respect and being used for genuine scientific and medical reasons and not in a trivial fashion.’
He added that a recent European decision to ban the patenting of treatments based on embryonic stem cells means his focus is likely to switch to other sources of cells.
Chris Mason, professor of regenerative medicine at University College London, described the research as ‘fascinating’ and a safe, ready supply would make a ‘massive difference’ to patients.
He added that production could be geared to demand, with bigger supplies on hand in the summer when there are more car crashes and gun fights. And while there are fears other ‘body parts’ made from stem cells can trigger cancer, blood cells should be free of this risk.
Blood donation services from around the UK and Ireland are providing the scientists with practical help and expertise. Lorna Williamson, of NHS Blood and Transplant, said the research was encouraging but ‘we will continue to rely, for some years to come, on our loyal, regular blood donors to help us meet the needs of patients for vital blood’.
Mr Turner, who is also the associate medical director of the Scottish National Blood Transfusion Service, is far from the only scientist in the race to crack the billion-pound market in artificial blood.
The French have started early-stage human trials with stem cell blood and other researchers around the world are making haemoglobin, the red blood cell protein used to ferry oxygen around the body.
Ideas being pursued elsewhere include using haemoglobin taken from cows as a blood substitute.

Some 1.6million Britons give blood each year. In the UK, stocks can fall during holiday periods, with supplies of the highly versatile O-negative type particularly vulnerable.

Sony pays Ericsson $1.47B, takes over phone business

Sony is ending a 10-year mobile-phone joint venture with Ericsson, buying out its business partner's 50 percent stake for 1.05 billion euros, or about $1.47 billion.

Through the deal, which had been rumored earlier this month, Sony Ericsson will become a wholly-owned Sony subsidiary, Sony said today. In addition, Sony will assume ownership for mobile phone patents and get other patent rights through a cross-license deal with Ericsson.
Consumers can expect a tighter integration between Sony's phones and the other main devices in the company's "four-screen strategy," said Sony Chief Executive Howard Stringer in a statement today.
"We can more rapidly and more widely offer consumers smartphones, laptops, tablets and televisions that seamlessly connect with one another and open up new worlds of online entertainment," Stringer said.
The partnership linked Sony's electronics experience with Ericsson's telecommunications technology. Sony Ericsson, late to recognize the rise of a new generation of smartphones, now is a fervent Android partners with its Xperia line.
The two companies will continue to be partners through a new effort, though. Sony and Ericsson are "setting up a wireless connectivity drive and develop the market's adoption of connectivity across multiple platforms," Sony said.
The patent deal, while not a surprise, could be helpful for Sony. A storm of patent-infringement suits sweeping the mobile marketplace right now, perhaps most notably pitting Apple, with iOS, against Samsung, a major user of Google's Android operating system.
Of this aspect of the partnership, Sony said, "The transaction also provides Sony with a broad intellectual property (IP) cross-licensing agreement covering all products and services of Sony as well as ownership of five essential patent families relating to wireless handset technology."

এই ছবিটা হচ্ছে বিশ্বের বিখ্যাত এবং পৃথিবী কাপানো ছবিগুলোর মাঝে একটা। এই ছবিটা তুলেছিলেন ফটোগ্রাফার Kevin Carter. Kevin Carter এই ছবিটি তুলেছিলেন ১৯৯৪ সালে সুদানে জাতিসংঘের খাদ্য গুদামের কাছে।

ছবিটার মানে কি জানেন??
শকুনটা অপেক্ষা করছে ছোট্ট শিশুটার মৃত্যুর জন্য। কারন মৃত্যুর পর শকুনটা এই শিশুটার শরীরের মাংস খাবে। এই ছবিটা তখন সারা দুনিয়াতে আলোড়ন তুলেছিল।

ছবিটা তোলার পর থেকেই তিনি মানসিকভাবে ভেঙ্গে পড়েছিলেন এবং এই কারনেই তিনি ছবিটি তোলার ৩মাস পড়ে সুইসাইড করেন ।

আত্মহত্যার আগে Kevin Carter নিন্মলিখিত বাক্যগুলো তার ডায়রিতে লিখে যান-
"Dear God, I promise Iwill never waste my food no matter how bad it can taste and how full i may be. I pray that He will protect this little boy, guide and deliver him away from his misery. I pray that we will be more sensitive towards the world around us and not be blinded by our own selfish nature and interests. I hope this picture will always serve as a reminder to us that how fortunate we are and that we must never ever take things for granted."

Science Discussion Forum / Re: Nokia's new interface is seriously twisted

One of them was being able to operate a device "blind," in other words, when not looking at it. You could reach into your pocket or purse to send a call to voice mail or to pause music.
A flexible phone could be instructed to take a photo when it's bent properly, he also suggested. I was skeptical, given the camera motion, but he also predicted that image stabilization advances will take care of that problem.
Another idea is scrolling through e-mail while walking, when it can be tough to precisely control an ordinary user interface.
And--unlike multitouch screens--it can be operated when you're wearing gloves.
I'm a bit skeptical, especially given that it requires two hands. But I could come around, especially if a one-handed device came around. And something flexible would be nice for fitting in a pants pocket, too--as long as sitting down didn't flex the phone and make it call somebody.

next revolution is coming to us.

Tapani Jokinen, who began working on the technology about two years ago as part of a Nokia group tasked with creating designs out of earlier-stage research, wouldn't say either when he thinks it'll come to market or how it worked.
But Chris Bower, stationed nearby at Nokia's "Future Lounge," had some ideas. He was showing an experimental apparatus with a bundle of carbon nanotubes in a flexible elastomer medium. The electrical resistance of the nanotubes changes as they're stretched, and measurements of the change let a computer control how a map zoomed in and out. The same approach could be used to control the flexible interface.
Jokinen was reluctant to predict whether it might become as widespread as multitouch user interfaces are today.
But he was enthusiastic about its possibilities.

The Nokia kinetic device scrolls through photos and music playlists when its edges are twisted.

Multitouch revolutionized user interfaces, and if Nokia researchers get their way, a mobile device that's sensitive to how it's being flexed could be the next revolution.

At the Nokia World show here, the Finnish mobile phone maker showed off its "Nokia kinetic device" with a flexible display. Gripped with two hands, it would scroll through music collections or photo albums when twisted. Bowing it inward or outward zoomed photos in and out or paused and played music, while tapping the corners panned through photos.
While it was a real computing device with a real OLED display, it's most definitely not a real product anyone could buy today. More firmly in the prototype category was a related flexible device that looked like a slim remote control; it could be controlled with a single hand.

So guyes be ready for next revolution of phone.

[Lumia 800: Nokia’s First Windows Phone

Nokia has officially unveiled Lumia 800, the first Windows Phone-based device from the Finnish mobile giant, at the Nokia World conference in London

The device is physically very similar to the MeeGo based Nokia N9. It is a beautiful polycarbonate device with a 3.7-inch, curved-glass, AMOLED screen.

The Nokia Lumia 800 sports a 1.4 GHz processor with hardware acceleration and a graphics processor, 512 MB of RAM and 16 GB of internal user memory. It also has a Carl-Zeiss, f2.2 aperture, 8-megapixel camera designed to work well in low-light environments. It will be available in three colors: cyan, magenta and black.

It’s not just about hardware; Microsoft has also packed the device with free software. Lumia 800 will be the only Windows Phone with Nokia Drive, which offers full, turn-by-turn voice navigation.

So Nokia Lover be ready to get it

বঙ্গোপসাগরে পড়েছে রোস্যাট
জার্মানীর রোস্যাট স্যাটেলাইট বঙ্গোপসাগরে ভেঙ্গে পড়েছে বলেই গবেষকরা ধারণা করছেন। ভারত এবং মিয়ানমারের মধ্যবর্তী কোন যায়গায় এ স্যাটেলাইটের সলিল সমাধি হয়েছে। স্যাটেলাইটির কয়টি টুকরো বঙ্গোপসাগরে পড়েছে তার কোনো গবেষকদের কাছে নেই। খবর প্রেস ট্রাস্ট অফ ইন্ডিয়া-এর।

জার্মান অ্যারোস্পেস সেন্টার (ডিএলআর) তাদের ওয়েবসাইটে বলেছে, ২.৭ টন ওজনের কৃত্রিম উপগ্রহটি ২৩ অক্টোবর পৃথিবীতে ফিরে আসে এবং টুকরো হয়ে বঙ্গোপসাগরে পড়ে।

জার্মান এক্স-রে স্পেস অবজারভেটরি বা রনজেন নামের এ কৃত্রিম উপগ্রহটিকে বলা হয় আরওএসএটি (রোস্যাট)। ১৯৯০ সালে এটি মহাকাশে পাঠানো হয়েছিলো। ১৯৯৮ সালে অক্ষম হয়ে পড়ে রোস্যাট। ১৯৯৯ সাল থেকেই গবেষকরা রোস্যাটকে পরিত্যক্ত হিসেবে ঘোষণা করেছিলেন।

স্পেস এজেন্সির পক্ষ থেকে জানানো হয়েছে, ভারতীয় সময় ভোর ৬ টা ২০ মিনিটে এটি ভারত এবং মিয়ানমারের বায়ুমণ্ডলে প্রবেশ করে। এরপর থেকেই এর কোনো তথ্য পাওয়া সম্ভব হয়নি। তাই এটি বঙ্গোপসাগরে পড়েছে বলেই ধারণা করা হচ্ছে।

The iPhone 4S is not the last major project that Steve Jobs worked on, according to one analyst. That would be the next iPhone--let's call it the iPhone 5.
The next-generation iPhone "was the last project that Steve Jobs was intimately involved with from concept to final design. For that reason...this product will establish the high water mark for iPhone volumes," Ashok Kumar, an analyst at Rodman & Renshaw, wrote in a research note this week. He expects the iPhone 5 to be a "cult classic" because of Jobs' involvement.
In the note, Kumar said the phone will have a slimmer profile and larger screen size but with the same dimensions as the iPhone 4S (the relatively-small 3.5-inch screen is not one of the 4S' best features). The iPhone is also expected to have LTE, or Long Term Evolution--what's sometimes referred to as 4G.
Another source, who I spoke with this week and who claims to have knowledge of the redesign, said the iPhone 5 is a "complete redesign. This is a very large project that Steve dedicated all of his time to. He was not that involved in the 4S because his time was limited."
That makes sense to me. Cosmetically, the iPhone 4S is identical to the iPhone 4. So no big change here. And though the 4S has been revamped on the inside, in some respects, it carries over technology already in the iPad 2: the same dual-core processor, same memory capacity, same accelerometer, same gyroscope, among other similarities.
So, it's probably not unreasonable to expect the iPhone 5 to be a "complete redesign," as the source said--meaning both externally and internally, though probably less so internally when compared with pronounced user-facing changes like the display size. (No telling what kind of plans Apple has on the software front: iOS 6? Siri 2?)
The iPhone 5 should debut around the time of Apple's Developer's Conference in the summer of 2012, according to Kumar's research note.
