Samsung's new Galaxy S9 and S9 Android smartphone models go on sale in the UK today, marking the company's latest assault on the market dominance of Apple's iPhone. The S9 will retail from £739 while the S9 is priced at £869 - notably less than the new iPhone X. The handset retailer is offering a free memory card with every S9 and S9 purchase, doubling the phones' capacities. The company's best deal for the S9 is on O2, which comes with 20GB of data and unlimited minutes and texts and is available for £49 a month for 24 months or £99 up front. Its best offer for the S9 is on EE, with 25GB of data and unlimited minutes and texts for £63 for a month for 24 months or £99.99 up front.

The value of bitcoin skyrocketed in 2017, and its rapid rise generated huge amounts of interest in it and other types of cryptocurrency. However, bitcoin is notoriously volatile, and a multitude of financial experts have advised people not to get involved, calling it a bubble that could burst at any moment. There are now fears that it already has. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph. The giant human-like robot bears a striking resemblance to the military robots starring in the movie'Avatar' and is claimed as a world first by its creators from a South Korean robotic company Waseda University's saxophonist robot WAS-5, developed by professor Atsuo Takanishi and Kaptain Rock playing one string light saber guitar perform jam session A man looks at an exhibit entitled'Mimus' a giant industrial robot which has been reprogrammed to interact with humans during a photocall at the new Design Museum in South Kensington, London Electrification Guru Dr. Wolfgang Ziebart talks about the electric Jaguar I-PACE concept SUV before it was unveiled before the Los Angeles Auto Show in Los Angeles, California, U.S The Jaguar I-PACE Concept car is the start of a new era for Jaguar.

The value of bitcoin has held reasonably steady in recent weeks following its rocketing value over Christmas and jittery plummet back to earth in January and February, as governments and central banks around the world continued to raise the spectre of future regulation. The volatile cryptocurrency's value has shifted wildly ever since mid-December - when it hit a record high of more than $19,850 (£14,214) - with frequent heavy drops and speedy recoveries. Bitcoin's value plummeted again shortly before Christmas, dropping by almost $2,000 (£1,449) in just an hour at one point, and almost slipping below the $11,000 mark (£7,970). It then bounced back, before tumbling again in mid-January, recovering again, and plummeting at the start of February before levelling out for the rest of the month and into early March. Aside from the looming prospect of regulation, a series of high-profile thefts have also had a hand in the sudden rapid dips in value bitcoin and its rivals have experienced - the most recent of which was a failed raid on the Binance cryptocurrency exchange.

Samsung's Galaxy S9 and S9 go on sale in the UK for the first time today as the South Korean phone giant launches its latest bid to challenge Apple's all-conquering iPhone. The company unveiled its newest Android smartphone at the World Mobile Congress (WMC) in Barcelona last month to widespread acclaim. The S9 will retail from £739 while the S9 is priced at £869 - notably less than the new iPhone X. While not drastically different in appearance to its predecessors, the S9 offers a number of subtle design tweaks that represent a clear advance on older models. The new version is 8.5mm thick and weighs just 163 grams - making for a lightweight feel in the hand - and has a 5.8 inch Quad HD curved Super AMOLED display that takes up most of the phone's front, its finger print recognition relocated to the rear.

How many doctors does it take to tell you how you're doing? The answer could soon be, none. Scientists and researchers across India are exploring the applications of artificial intelligence in health care -- from helping diagnoses illnesses to monitoring critical care. "Artificial intelligence -- or cyber-physical systems, as I like to call them -- can collect digitised data or generate data, analyse and make decisions based on it," says professor Ashutosh Sharma, secretary of the union government's department of science and technology. "A big advantage of AI in healthcare is that it can help where there is a scarcity of human resources, which is the case in many rural areas," adds Dr P Anandan, CEO at the Wadhwani Institute for Artificial Intelligence (Wadhwani AI).

Credit risk or credit default indicates the probability of non-repayment of bank financial services that have been given to the customers. Credit risk has always been an extensively studied area in bank lending decisions. Credit risk plays a crucial role for banks and financial institutions, especially for commercial banks and it is always difficult to interpret and manage. Due to the advancements in technology, banks have managed to reduce the costs, in order to develop robust and sophisticated systems and models to predict and manage credit risk. To predict the credit default, several methods have been created and proposed.

The elimination of millions of jobs by battalions of artificial intelligence-powered robots makes for sensational headlines. But like many stories regarding both the threat and opportunity from technological change, the real story is both more nuanced and more interesting. A recent report from the World Economic Forum predicted that intelligent automation could eliminate five million jobs in developed countries by 2020. So, you would think a recent spate of announced job reductions in Japanese banking over the next decade – over 30,000 in total at the three major banking groups - would be a cause for concern. Instead, on a recent trip to Tokyo, I heard from a senior executive at one of those banks that automation is vital to deal with a shrinking labor force as the country ages, and that busy robots are a better alternative for the country than unfilled job vacancies.

Technology is changing the way we work and the jobs we do. Will artificial intelligence and robots relieve us of humdrum tasks, making our working lives easier, or will they take our jobs away altogether? As part of a new series called the Future of Work, we look at the growing popularity of "daigou" - Chinese expats who buy consumer goods for people back home in China. Sandra Lee describes herself as part of a "global phenomenon". A 37-year-old Chinese expat who lives in Central Coast, Australia, she makes money by selling Australian goods to people back in China.

Reports that robots, automation and artificial intelligence are going to put millions of us out of work may sound troubling, but should we believe them? That largely depends on whether we're technology optimists or pessimists. In our Future of Work series we look at how jobs might change in the future.

But an unusual new robotics project may be able to help. "Shelly" is a robotic tortoise developed by engineers from South Korea's Naver Labs and Seoul National University. The difference between Shelly and other kinds of bots some of you may have had in the classroom is that this one shows emotional feedback based on how it's treated. Stroke the robotic reptile's embedded LED surface, which is equipped with vibration sensors that can detect touch, and Shelly will wiggle her head and limbs. Hit, kick, or drop Shelly, however, and her head will retract inside her body as if she's frightened.
