​London, June 30 (IANS) Sleeping more or less than the average seven hours may increase the risk of developing diabetes in men, a new study warns.

The findings showed that men who slept the least and the most were more likely to have an impaired ability to process sugar compared to men who slept an average amount of about seven hours.

The men at either end of the spectrum had higher blood sugar levels than men who got the average amount of sleep.

Conversely, women who slept less or more than average were more responsive to the hormone insulin than women who slept the average amount.

They also had enhanced function of beta cells - the cells in the pancreas that produce the hormone insulin.

This suggests lost sleep may not put women at increased risk of developing diabetes, the study said.

"In men, sleeping too much or too little was related to less responsiveness of the cells in the body to insulin, reducing glucose uptake and thus increasing the risk of developing diabetes in the future," said Femke Rutters from VU University in the Netherlands.

During the last 50 years, the average self-reported sleep duration for individuals has decreased by 1.5 to two hours.

The prevalence of diabetes has doubled in the same time period, the researchers noted.

"Even when you are healthy, sleeping too much or too little can have detrimental effects on your health," Rutters said adding, "this research shows how important sleep is to a key aspect of health - glucose metabolism."

The study, published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism, is the first to show opposite effects of lost sleep on diabetes risk in men and women.

In the cross-sectional study, the team examined the sleep duration and diabetes risk factors in 788 healthy adults ranging in age from 30 to 60 years old.

The researchers observed sex-specific relationships between sleep duration and glucose metabolism in the participants.​

​New York, June 30 (IANS) Facebook has made changes in news feed ranking to ensure you do not miss updates from families and friends amid the flood of information on the social media platform of over a billion users.

"The goal of News Feed is to show people the stories that are most relevant to them. Today, we’re announcing an update to News Feed that helps you see more posts from your friends and family,” Facebook executive Adam Mosseri wrote on a blogpost on Wednesday.

The new changes mean that wedding photographs of your close friend would get more prominence than the stories linked to what happened in Turkey or for that matter in India.

"When we launched News Feed in 2006, it was hard to imagine the challenge we now face: far too much information for any one person to consume,” Mosseri said.

"In the decade since, more than a billion people have joined Facebook, and today they share a flood of stories every day. That’s why stories in News Feed are ranked ? so that people can see what they care about first, and don’t miss important stuff from their friends,” Mosseri explained.

"If the ranking is off, people don’t engage, and leave dissatisfied. So one of our most important jobs is getting this ranking right,” the post said.

The social networking giant recently faced allegations of political bias in the selection or prominence of stories in its "Trending Topics" feature. An internal investigation of the organisation, however, revealed no evidence of any systematic political bias.

"Facebook was built on the idea of connecting people with their friends and family. That is still the driving principle of News Feed today,” Mosseri said.

"We are not in the business of picking which issues the world should read about. We are in the business of connecting people and ideas ? and matching people with the stories they find most meaningful,” Mosseri pointed out.​

​New York, June 29 (IANS) Adolescents living in neighbourhoods with more greenery may exhibit less aggressive behaviour, finds a new study.

The findings showed that increasing greenery levels like parks, golf courses or fields, might lead to a 12 per cent decrease in clinical cases of aggressive behaviour. 

"Our study provides new evidence that increasing neighbourhood greenery may be an effective alternative intervention strategy for an environmental public health approach that has not been considered yet," said Diana Younan, doctoral student, at the University of California in the US. 

Nine to 18-year-olds who lived in places with more greenery had significantly less aggressive behaviour than those living in neighbourhoods with less greenery. 

Both short-term (one to six months) and long-term (one to three years) exposure to green spaces within 1,000 metres of residences were associated with reduced aggressive behaviour. 

The behavioural benefit of green spaces equated to approximately two to two-and-a-half years of adolescent maturation.

In addition, these benefits existed for both boys and girls of all ages and races/ethnicities, and across populations with different socio-economic backgrounds and living in communities with different neighbourhood quality.

"It is important that we target aggressive behaviours early. Identifying effective measures to reduce aggressive and violent behaviours in adolescents is a pressing issue facing societies worldwide," Younan added.

Factors such as age, gender, race/ethnicity, socio-economic status, parents' educational background, occupation, income level, or marital status and whether their mother smoked while pregnant or was depressed did not affect the findings.

For the study, the team followed 1,287 adolescents from Southern California who were aged nine to 18 years to see whether greenery surrounding the home could reduce aggressive behaviour.

The results will be published in the forthcoming issue of the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP). ​

I stay in rural Maharashtra. We have reached a stage in life where we hardly shop but sometimes need specialty items like books, computer peripherals, herbal teas and the like. These items are not available in our rural town of Phaltan where we live and so we do online shopping. In the last year or so we have discovered the power of such shopping. In the recent past, we would go once a month to Pune (110 km away) to buy a few things. Now because of online shopping, such trips have drastically reduced - and for good reason. It takes about three hours to reach Pune, driving over pot-holed roads, which produces back pain. Besides, the traffic jams and pollution in or near Pune add to the discomfort. Also going to Pune for a few items was quite a chore and waste of energy and time. Now online shopping allows us the luxury of getting all sorts of items at home. Such online shopping is being discovered in all rural towns and areas around the country. However, for such e-commerce to take place, it is necessary to have a good internet connection, ability to sift through the various items offered and zeroing on selection of quality material. All this is possible by googling the items and comparing their prices and specifications. I find that the rural population is learning this search-and-pick at amazing speed - which is reflected in the increase of sales in rural areas via online shopping. They also order items seen on TV ads and those passed by word of mouth. With mobile penetration in rural India, this shopping is also facilitated by various smartphone apps so that desktop PCs are not required. Nevertheless, this online shopping is fuelling consumerism in rural areas and is the engine which is helping it to urbanize. It is happening because it produces a win-win situation. For example, one can get quality goods at substantial savings as they are usually much cheaper than what one would pay in a shop in Pune or other big cities. Besides, most of the time the goods are shipped free and cash-on-delivery basis. Also, the time and energy used in actual shopping and going to the big city are saved. This is the reason why e-commerce has spread so rapidly all over the world and rural India is only now getting the benefits of this revolution. The foray of the online companies in rural India is also fuelling the job market - it is providing employment to a large number of rural youth as delivery boys. Besides, it has given a shot in the arm to loss-making India Post since their large network of postmen is being used by e-commerce companies to penetrate rural areas. However, such shipments are energy intensive. For a small item the packing is almost three-to-four times its size. This is waste of material, and adds to the weight of shipment and to the transport energy cost. Secondly, quite a number of times, the item which is manufactured locally is shipped to big cities and then again to the final destination. For example, we ordered a packet of mango pickle (of a brand that is not available in Phaltan) which is manufactured about 45 km from our rural town. This packet was shipped to Bangalore from where it came to us. This is a real wastage of energy in transport but the shipping company may be finding it cheaper to do so for whatever reasons. Yet with all this travelling around we got this packet at nearly half the price of what we would have paid in a Pune shop. So, how do companies like Amazon, Flipkart, Snapdeal and others who have big online presence in India still make money on such transactions? Data from their financials reveals that presently all of them are losing money - primarily because it is the start of e-commerce boom in India. However, they feel that there is a great future in online shopping and with time, their profits will increase. Thus only those companies with deep pockets will survive since they alone have the staying power to penetrate the rural markets. (Anil K.

Panaji, June 27 (IANS) McDonald's will invest Rs 700-750 crore over the next few years to expand its chain in India, especially in emerging cities and towns, a senior company official said on Monday. The global fastfood chain's vegetarian menu, specifically designed for India, has also found takers in Singapore and the Middle East, Ranjith Paliat, Vice-President, business operations, McDonald's India (West and South), said. He said Indian food items like samosa or dosa on the McDonald menu would depend on customer feedback. "Our customers keep giving us feedback on the way forward," Paliat told IANS when asked if McTikki, an adaptation of the predominantly north Indian 'aloo-tikki', could possibly see competition in the form of McSamosa or McDosa in the future. India was the first market where McDonald's introduced a vegetarian menu soon after the Illinois-headquartered company set up operations in the country in 1996. "It was tried out in Singapore and it was tried out in the Middle East. The products taken there were aloo-tikki and McVeggie. So with growing vegetarianism, there is an interest in what we are serving and how can they take it," Paliat said.​

New Delhi, June 29 (IANS) Just a few years ago, seeing an Indian youth with a Nokia or an office-goer with a BlackBerry device on the road was a common sight. In 2009, about 70 per cent of smartphones sold globally had operating systems offered by BlackBerry and Nokia and the two stalwarts were going strong. But even tech leaders can, at times, fail to gauge when a particular phenomenon can go extinct. The mobile operating systems offered by Google, Apple and Microsoft, which account for nearly 99 per cent of sales today, were in less than 25 per cent of mobile devices sold at that time, says a recent blog post by WhatsApp which has decided to end its support to BlackBerry phones and those powered by Nokia's Symbian OS by the end of this year. After acquiring Nokia for $7.2 billion in 2013, Microsoft soon realised it made a big mistake and is now selling off Nokia's phone-making business to Apple's supply-chain partner Foxconn. With the Nokia acquisition, Microsoft actually placed a bet on hardware which has never been its strength. On the other hand, Canadian mobile company Blackberry reported a $670 million loss in the first fiscal quarter this year -- its biggest loss in over two years. Is it time for Nokia and Blackberry to quit the smartphone business? "Blackberry can't catch up on the plethora of offerings iOS and Android players are providing with their vast ecosystem. The surge in vendors offering android devices at competitive prices dominate the smartphone market globally. Similarly, Windows-based smartphones are likely to decline sharply given the fact that Nokia is no longer a part of Microsoft," says Karthik J, Senior Market Analyst (Client Devices) from International Data Corporation (IDC). "The high-end Blackberry Priv (based on Google's Android OS) smartphone was a drastic approach the vendor took to revive by moving away from its homegrown OS to Android but failed to create ripples in the market," Karthik told IANS. According to experts, Blackberry was a little late in coming up with an Android-based smartphone. "Priv is launched at the premium end which accounts for a smaller pie of smartphone market and dominated by Samsung and Apple. Smartphone market is already highly populated with numerous vendors offering products across multiple price segment. Also, adding to this is the fact that smartphone market's growth is saturating in key markets like the US and China," Karthik told IANS. It is not just WhatsApp that decided to end support for BlackBerry OS 10 services by the end of this year. Facebook too is leaving the BlackBerry platform after announcing it will discontinue support of its application programming interfaces (APIs) for BlackBerry. "BlackBerry needs to focus on feature phone market and concentrate when it comes to India if it wants to beat Chinese and established players in the country. They always had top-of-the-line security and they can still cash on it in upcoming devices when data security is the buzzword," notes Vishal Tripathi, Research Director at global market consultancy firm Gartner. According to Faisal Kawoosa, Lead Analyst with CyberMedia Research (CMR), a market research firm, one of the key strengths for BlackBerry has been security and software. "They should become a technology company, licensing their solutions to original design manufacturers (ODMs) rather than attempting and reattempting to emerge in the smartphones," Kawoosa told IANS. "The recent developments indicate that the pioneer of the smartphone should now take up things differently and look up to strengthen its Android platform and in creating some great hardware too," notes Krishna Mukherjee, Analyst (Telecoms) at market research firm CyberMedia Research (CMR). When it comes to Nokia, with a proper revival approach, the Finnish company still holds a good chance to make a strong re-entry into the highly populated smartphone market in India. "Nokia continues to have a strong brand perception in India especially in lower tier cities and with its in-depth knowledge of the market, possibly it is still not too late for Nokia to make a comeback," Karthik told IANS. According to Kawoosa, Windows still is the default enterprise OS and mobility is an extended piece within enterprise communications. "So there is a connect. It is only that Microsoft has to develop the solid links. There have to be compelling reasons," he suggests. "The only way out for Nokia would be to go back to its roots and spin all its strategies from scratch. Again, Nokia's strength has been its technology orientation. It should focus on research and development and license its technology and patents to the mobile world," adds Kawoosa. All is not lost yet for Nokia and Blackberry, the two handset legacies of our times -- if they understand the changing needs of the Next-Gen smartphone users, and act.​

Chandigarh, June 28 (IANS) To support growth of tourism sector in the state, the Haryana government on Tuesday declared tourism as an industry for land use purpose.

The decision to this effect was taken in-principle in a meeting of the state cabinet, chaired by Chief Minister Manohar Lal Khattar here on Tuesday.

The move has been made to attract big investment in tourism projects in Haryana.

"The components that have been classified as land use under industry include all tourism projects and activities with the exception of activities like hotels, tourist resorts, eat streets or outdoor dining areas or promenades or food courts or restaurants and commercial components within recreational or commercial activities," a Haryana government spokesman said here.

"These provisions would be applicable to mega projects only involving investment of Rs 100 crore or above or employing more than 500 people. These would be applicable with prospective effect to all new as well as expansion projects involving an investment of Rs 50 crore," he added.

Haryana was the pioneer state in highway tourism in the 1970s and 1980s with government-run and private outlets along highways running successfully. However, in the absence of further impetus, the state has lagged behind on the tourism front despite having a rich historical background and being the land of the Mahabharata battle.

​New Delhi, June 26 (IANS) Excessive use of electronic gadgets, including mobile phones and tablets, can cause "tech neck" that leads to early signs of ageing, health experts have warned.

According to experts, "tech neck", which leads to sagging skin, dropping jowls, and creases above the clavicle, seriously affects facial looks of the person by causing frown lines, undereye bags, and horizontal lines on the neck along with fat prominences.

"People who bend down constantly for long hours while using any handheld electronic device, like smartphones, tablet or computers, are more likely to get wrinkles. The bending position while texting on mobile phones can cause neck, back and shoulder pain, apart from headache, numbness, tingling in the upper limb and pain in hands, arm, elbows and wrists," said Vinod Vij, Cosmetic Surgeon, at Mumbai-based Fortis Hospital.

A recent report by the Internet and Mobile Association of India (IAMAI) had revealed that the number of mobile internet users in the country was expected to reach 371 million by June 2016. As much as 40 per cent of the users consist of youngsters between the age group of 19-30.

Experts have said that the frequent forward flexion causes changes in the cervical spine, curve, supporting ligaments, tendons and musculature, as well as the bony segments, commonly causing postural change.

Mohan Thomas, Senior Cosmetic Surgeon, Cosmetic Surgery Institute, said: "As people do not realise the negativity they are causing to their neck bone and the skin, tech obsessed people should take necessary steps to avoid the overuse of the electronic gadgets."

He said the overuse of smart phones causes shortening of the neck muscles.

"Apart from shortening of the neck muscle it also increases the gravitational pull on the skin. Ultimately, this results in sagging skin, double chin, marionette lines (vertical lines from lips to chin) and loose jowls (drooping jawline). All these signs have been collectively labelled medically as "smartphone face," he said.​

​New Delhi, June 28 (IANS) Besides following a hydrating and high fibre diet that will help to stay cool, also indulge in power-packed foods to stay energised, says an expert.

Dolly Kumar, health expert, founder and Director at health brand GAIA, shares how:

* Most of us like to enjoy light and healthy meals during summer since they are easy to digest and don’t leave us feeling bloated, uncomfortable and lazy. A healthy quick fix is to start the day with muesli along with skimmed milk and fresh fruits for breakfast. Rich in dietary fibre, proteins, iron and anti-oxidants, this power-food is extremely healthy. 

* Summer is also the time to indulge in cooling beverages which keep us energised and refreshed all day. Green tea is a wonderful beverage to drink early in the morning or even late evenings. Green tea is packed with anti-oxidants and is known to strengthen the immune system and improve memory. Along with its aroma and pleasant taste, your body is bound to stay hydrated and fresh all summer. Add a dash of honey and squeeze a lemon in your cup of green tea and add some tanginess and zest to your day.

* Munch on healthy sweet and salty snacks regularly. Trail mix is a wonderful snack that will help you regain that lost energy. High on proteins and good fats, most trail mixes are packed with the goodness of assorted nuts, dried fruits and crunchy seeds. The mix provides instant energy from the proteins, dietary fibres and good fats found in its ingredients. ​
