​New York, March 17 (IANS) More than 50 per cent of millennials in the US prefer checking Snapchat first over other social media platforms such as Facebook, Instagram, and LinkedIn, the results of a new survey suggest.

The survey involving nearly 10,000 college students found that 58 per cent of them check Snapchat over Facebook, Instagram, and LinkedIn combined. 

Instagram accounted for 27 per cent, Facebook for 13 per cent, and LinkedIn for two per cent, or a total of 42 per cent, showed the new data gathered by LendEDU, an online marketplace for student loans and student loan refinancing.

The findings suggest that Snap Inc., parent company of messaging app Snapchat, may not only survive the volatile Wall Street environment, but prosper.

Snap Inc has been the word on Wall Street since it went public on March 2.

Snap rode its immense popularity to produce eye-popping numbers during its initial offering, with a first day closing price at $24.53. 

In the days following the IPO, shares of Snap traded lower as exuberance and volume settled. 

But the messaging app's popularity among millenials (born between 1980 and and early 2000s)can help the company prosper in the stock market, according to the new results.

"Overall, Snap's access and importance to millennials will be the driving force behind their success in the stock market," LendEDU said in a report on Thursday.

For the study, LendEDU has gathered this data under license from polling company WhatsGoodly.

According to Snap, the majority of Snapchat users are aged 18-to-34 years old. On an average, these users visit the app 18 times a day for a combined 25 to 30 minutes. 

Additionally, users younger than 25 visit the application more than 20 times a day for more than 30 minutes.

​Madrid, March 16 (IANS) iPhone 7 was a top seller in EU5 with iOS holding a 22.7 per cent share -- a climb of 2.4 percentage points. Android was second and accounted for 74.3 per cent of smartphone sales, with a marginal increase from 72.9 per cent in the three months ending January, a new report said. EU5 stands for European Union Five, in which France, Germany, Italy, Spain and Britain are members. According to Spain-based consumer research firm Kantar Worldpanel, iOS achieved continued growth across most regions, except for Japan, Spain and Urban China. Android also continued to post market share increases in all regions but the US. The report said iOS and Android were the only two dominating operating systems in the world with BlackBerry OS, Symbian or Windows Mobile losing their grip. "February's Mobile World Congress 2017 demonstrated the true state of the market, with re-emerging brand names Nokia and Blackberry capturing a lot of attention, but now operating on Android rather than on their own legacy operating systems," said Lauren Guenveur, Global Consumer Insight Director for Kantar Worldpanel ComTech. Two all new Android smartphones -- Nokia 3 and 5, plus the expanded global release of the Nokia 6 -- could do well in Western Europe due to loyalty to the Nokia brand name, the report noted. "HMD Global's focus on revitalising the Nokia name seems concentrated on quality for cost. Its three new Android phones are priced at Euro 229 or less, with Android Nougat, Google Assistant, aluminium construction and otherwise solid mid-range specs," added Dominic Sunnebo, Business Unit Director for Kantar Worldpanel ComTech Europe. Meanwhile, Android remained dominant in Asia accounting for 83.2 per cent of smartphones sold in Urban China -- an increase of 9.3 percentage points versus the same period a year ago. Huawei continued to dominate the region at 26.6 per cent. Apple and Xiaomi are the second and third largest manufacturers in Asia, with 16.6 per cent and 14.5 per cent shares respectively. The picture was different in the US. Android accounted for 56.4 per cent of smartphone sales in the US -- down 1.8 percentage points from the period a year earlier. iOS accounted for 42 per cent of smartphone sales -- up 2.9 percentage points year-on-year.

New York, March 16 (IANS) Scientists have developed a new pill that can act as non-invasive alternative to colonoscopies -- an effective way to screen for colon cancer -- and help identify growths called polyps.

Colorectal cancer is the third-leading cause of cancer deaths in women and second leading cause in men. Early detection and screening are essential to reduce the rates of colorectal cancer.

The pill -- PillCam Colon 2 -- contains two miniature cameras on either end. After being ingested by the patient, the capsule travels through the digestive tract, captures images and wirelessly transmits them to a recorder the patient wears on a belt.

Like a colonoscopy, the system can help identify growths called polyps, said researchers from Loyola University in Chicago, US.

During a standard colonoscopy, a flexible tube (colonoscope) is inserted into the rectum and guided by a physician through the colon. A camera at the end of the colonoscope allows for visualisation of polyps.

However, some patients cannot tolerate the procedure, or may be at higher risk for sedation, the researchers said.

With the new system, the patient swallows the capsule with water. After the non-reusable capsule is excreted, it's flushed down the toilet. The patient returns the recorder to the physician's office. If a polyp is found, the patient arranges to undergo a colonoscopy to remove the growth.

"Early detection has been proven to save lives, and the video capsule system offers a convenient screening test for people who are unable to have a complete colonoscopy," Mukund Venu from Loyola University, said in a statement.

The US Food and Drug Administration approved the capsule system for patients whose anatomy of the colon makes it difficult to guide a colonoscope through the entire colon and for patients who have elevated risk of complications due to age or other reasons.

​Bengaluru, March 15 (IANS) Software major Wipro on Wednesday announced opening an automotive engineering centre at Detroit in the US to drive innovation in connected vehicles concepts.

New York, March 16 (IANS) A common genetic variant that accelerates normal brain ageing in older people by up to 12 years has been identified by US researchers.

The findings could point towards a novel biomarker for the evaluation of anti-ageing interventions and highlight potential new targets for the prevention or treatment of age-associated brain disorders such as Alzheimer's disease, the researchers said.

"If you look at a group of elderly, some will look older than their peers and some will look younger. The same differences in ageing can be seen in the frontal cortex, the brain region responsible for higher mental processes," said Asa Abeliovich, Professor at Columbia University Medical Centre (CUMC) in the US.

The results, published in the journal Cell Systems, showed that many of these differences are tied to variants of a gene called TMEM106B. About one-third of people have two copies of TMEM106B and another third have one copy.

People who have two 'bad' copies of this gene have a frontal cortex that, by various biological measures, tends to appear 12 years older than those who have two normal copies.

"TMEM106B begins to exert its effect once people reach age 65. Until then, everybody's in the same boat, and then there's some yet-to-be-defined stress that kicks in. If you have two good copies of the gene, you respond well to that stress. If you have two bad copies, your brain ages quickly," Abeliovich explained.

"It's in healthy tissue that you start to get disease. It appears that if you have these genetic variants, brain ageing accelerates and that increases vulnerability to brain disease. And vice versa: if you have brain disease, the disease accelerates brain ageing," he noted. 

​London, March 15 (IANS) Sixty-eight per cent of organisations use artificial intelligence (AI) for IT functions, but 70 per cent believe AIs greatest impact by 2020 will be in marketing, customer service, finance and HR, a new study said on Wednesday.

​New York, March 15 (IANS) Software giant Microsoft has rolled out its collaboration and communication platform Teams to all its 85 million monthly active users of Office 365 for free.

Seoul, March 15 (IANS) After working for foldable displays for years, South Korean giant Samsung will start manufacturing game-changer smartphone that can be folded in the third quarter of 2017. "Q3 2017 is already marked in some calendars as the time for IFA 2017 in Berlin. Samsung usually introduces the Galaxy Note series, but that does not exclude the possibility of having a foldable smartphone presented to the crowd, or at least tease one for a later date," GSMArena.com reported on Wednesday. Last year, Samsung has reportedly filed a patent with the Korean Intellectual Property Office for a smartphone that can be folded in half and is expected to arrive next year. Called the Galaxy X, the front of the smartphone will sport traditional Samsung home button in between a back button on the right and a menu button on the left, media reports said.

New York, March 15 (IANS) Google will maintain its dominance and account for 40.7 per cent of US digital ad revenues in 2017 -- more than double Facebooks share, market research company eMarketer said. According to eMarketer's forecast, the US digital ad spending will reach $83 billion in 2017, representing an increase of 15.9 per cent. eMarketer expects Google's share of the search market to grow 16.1 per cent to $28.55 billion in 2017 and the search giant will claim roughly 78 per cent of total US search ad revenues this year. "Google's dominance in search, especially mobile search, is largely coming from the growing tendency of consumers to turn to their smartphones to look up everything from the details of a product to directions," Monica Peart, Forecasting Analyst, eMarketer, said in a statement. As Google dominates search, Facebook rules display. The social network's US display business will jump 32.1 per cent to $16.33 billion, capturing 39.1 per cent of the US display market, taking share away from Google, Yahoo, and Twitter, the findings showed. Facebook's revenue growth can be attributed to growth in both usage and time spent, which continues to draw advertisers in greater numbers. Instagram is also helping to drive Facebook's revenue growth. In fact, Instagram will make up 20 per cent of Facebook's US mobile revenue this year, up from 15 per cent last year. "Facebook users are increasingly captivated by videos on the platform -- not just on Facebook, but on Instagram as well. Video, both live and recorded, is a key driver of growing user engagement and advertiser enthusiasm," added Peart. Meanwhile, Google's display business will rise to $5.24 billion, but its share of the display market will drop to 12.5 per cent, the report noted. In 2017, Snapchat's ad revenue will grow 157.8 per cent to $770 million in the US. That's slightly lower than the $800 million previously projected, due to higher-than-estimated revenue sharing with partners. Snapchat's ad business, which is made up entirely of mobile display, is still small. Snapchat will account for 1.3 per cent of the mobile ad market this year. By 2019, that will grow to 2.7 per cent, the report added.

​Hong Kong, March 15 (IANS) It is easy to remember Hong Kong for its enormous variety of food and leisure, and the way these can be relished in quick time. But for me, Hong Kong is also about neatness, planning, seamless transport and the no-fuss attitude of its street vendors who make budget shopping a memorable experience.

Hong Kong delighted me in several ways. The manner in which people of the city have overcome challenges posed by nature, created opportunities for themselves and made the city one of the top business hubs of the world seemed worth emulating.

Hong Kong, which became a special administrative region (SAR) of China in 1997 after 150 years of British administration, has few natural resources. Given that it's tiny (its land area is only 1,073 sq km), most commercial and residential buildings shoot skyward. Hong Kong has the most skyscrapers in the world for any city.

The city's small area has its own advantages for a tourist. For instance, the city's historic tram, it's mass transit railway (MTR) system, colourful taxis, double-decker buses and the famous star ferry can all be experienced one after the other within a few hours while hopping from one place to the other.

Hong Kong has shops to cater to every pocket and taste and there is enough for a budget tourist to explore. I, too, searched for options that were not hard on the pocket.

The Ladies' Market near Mong Kok MTR station had vendors selling an array of products including bags, purses, shoes, track suits, T-shirts and accessories. A large number of products were for ladies and they were also the ones managing most of the stalls.

I bargained to bring down prices, but it was not always easy. A survey of the market helped identify vendors who seemed inclined to bring down prices. Trials were not allowed on garments and one had to go by one's estimation. Several vendors seemed to have difficulty with English but, nevertheless, managed to communicate in a business-like manner.

The evening market near Sham Shui Po MTR station was also quite an experience and I found a few people from India and Pakistan surreptitiously selling their wares, mostly garments and shoes, on the pavement. They told me that they did not have valid documents to engage in jobs or businesses and were planning to return home in due course. The present tensions between India and Pakistan did not matter to them as they stayed and dined together. They kept track of domestic developments in their countries through WhatsApp messages and the Internet.

The market had an array of products including watches, clocks, toys, phones, accessories and electronic goods. But one had to be careful about prices. A wireless microphone Hifi speaker, being sold by a street vendor at HK$150 (Rs 1,260), was priced at a nearby shop for HK$280.

I also realised the enormous spread of China-made goods and the variation in their prices at different places. An alarm clock I had seen in a gift shop in east Delhi for Rs 500 was available at a local shop in the market for HK$35 (Rs 315) and I could purchase it for HK$32 (Rs 288) after a little bargaining. Quite a steal!

But while Sham Shui Po is a working class neighbourhood, I also spotted a street market in upmarket Wan Chai. Here, the quality of products was better though a little higher priced. There were also no-frills shops along some the main roads in Wan Chai which offered good quality garments, purses and bags at very decent prices.

Hong Kong offers a rich variety of cuisine and has thousands of restaurants to cater to various tastes. Apart from venues for fine dining, the city has several road-side eateries which offer a mind-boggling variety of non-vegetarian stuff.

There are options for vegetarians too, but one has to look at the menu and the medium of cooking carefully. Indian food is also becoming increasingly popular and vegetarianism is gaining ground with the "Green Monday" campaign.

Hong Kong's cleanliness is remarkable and demonstrated to me the vast distance we have to cover to make our cities clean despite programmes like Swachh Bharat (Clean India).

Tourists have their hands full in Hong Kong and are spoilt for choice. Apart from its well-known attractions like Disneyland and Ocean Park, Hong Kong offers a lot to explore including beaches, city parks, museums, harbour views, cycling, modern architecture and visits to outlying islands.

The city also takes continuous care of its infrastructure to keep it world class. The traffic flows smoothly on well-planned roads and magnificent bridges. An express rail link is being built to provide speedy connectivity with mainland China. The transport system in Hong Kong is neatly integrated and provides multiple options to reach a destination depending on time and money a traveller is willing to spend.

Hong Kong, it was clear, innovates constantly to create opportunities for its people and new avenues of recreation for tourists.
