Among the most well-rounded cars in its class and winner of the Best Compact Premium Sedan segment at the 2017 Middle East Car of the Year awards, the Audi A4 is sporty yet classy and user-friendly though loaded with high tech equipment. 

Driven in top 45 TFSI Quattro specification — next to “S” or “RS” high performance variants – the A4 is quick yet efficient and refined, and delivers a comfortable ride, composed handling and reassuring road-holding in one package.

 

Elegant and unpretentious

 

Quiet, refined and efficient, the A4 is designed with segment-best CD0.23 aerodynamics for base models and Cd0.27, as driven, and features several wind-cheating measures, including and under body cover and an aerodynamic mirror design.

Built using a combination of materials, including high strength steel and lightweight aluminium, it is lighter yet more spacious than its predecessor. Utilising other weight-reduction measures like lighter electric power steering, it makes a 120kg weigh saving, while aluminium suspension reduces unsprung weight for improved comfort and better handling.

An evolutionary design that is sharper and more sculpted than the car it replaces, the A4 is at the same time distinctly smart and assertive in aesthetic, yet, understatedly elegant and unpretentious. Its big hexagonal grille is flanked is framed by strongly browed and slim lights and big side intakes. Surfacing is chiselled and subtly detailed, with prominent sills and tight a crease-line across the flanks. Meanwhile, a level waistline lends it a grounded look that alludes to its Quattro four-wheel-drive, and provides good visibility.

 

Responsive and refined

 

The most powerful garden-variety A4, the 45 TFSI is powered by turbocharged 2-litre four-cylinder engine powering all four wheels through a smooth and swift shifting 7-speed automated dual-clutch S-Tronic gearbox with economy and manual modes drive modes, and a stop/start system to help achieve low 6.3-litre combined fuel efficiency. A testament to just how far the combustion engine has developed in recent times, the mid-range A4 45 TFSI is now faster, more powerful and economical than Audi’s breakthrough 1980s model and iconic high performance Quattro. 

Producing 248BHP at 5000-6000rpm and 273lb/ft throughout a broad 1600-4500rpm range, the 45 TFSI Quattro launches eagerly off the line, with quick spooling turbo and four-wheel-drive traction ensuring power translates effectively to motion. Powering through 0-100km/h in 5.8-seconds and capable of 250km/h, the 45 TFSI is responsive from low-end and effortlessly versatile in mid-range. 

Refined and smooth, the A4 has a faint yet distinct growl as it quickly, but progressively climbs to its peak performance top-end. Meanwhile, its intake manifold is integrated into the cylinder head for improved thermal management.

 

Sure-footed handling

 

Sure-footed and tenaciously grippy, the A4’s Quattro system sends 60 per cent power rearwards for eager dynamics and balance, but can reallocate 85 per cent power rearwards or 70 per cent frontwards for improved handling, road-holding and safety when necessary. For 2018, the 45 TFSI will also be offered with Audi’s new Quattro Ultra system, which drives the front wheels in normal conditions and engages the rear wheels as necessary. Reducing friction and improving fuel efficiency, the new system is seamless in operation, it can even pre-empt when four-wheel-drive is necessary.

Riding on five-link front and rear suspension with upper links integrated directly into bodywork the A4 is designed to for supple absorption of longitudinal forces while retaining lateral stiffness. Its new suspension design also makes the A4 handle with tidy and crisp eagerness into corners, regardless of its longitudinal engine being positioned just ahead of the front wheels. Through winding Italian roads on initial test drive, the A4 was committed, fluent and poised, with agility further enhanced by a brake-based torque vectoring system and optional rear sport differential.

 

Ergonomic and advanced

Whether on imperfect and winding Italian routes or smooth and straight Dubai roads during a second test drive, the A4 — with optional adaptive dampers — proved composed and comfortable at speed and forgiving and settled over more textured segments. Refined inside from vibrations, noise and harshness, the A4’s cabin has an airy ambiance and terrific driving position with good visibility, high level of steering and seat adjustability, seating support and perfectly centred seat, steering wheel and pedals position. Rear space was meanwhile better than most in its segment.

Uncluttered, ergonomic and stylish inside, the A4’s cabin has a quality feel to its build, textures and materials, including open pore woods. User-friendly and well-equipped, it features a configurable Virtual Cockpit instrument cluster screen, head’s up display and optional 8.3-inch infotaiment system with voice control, smart phone integration and rear seat tablet. 

An extensive suite of semi-autonomous, safety and driver assistance systems can prevent collisions at 40km/h and reduce severity to 85km/h, and assume steering control on well-developed roads, up to 65km/h, and anticipate and prepare for corners.

Eating leafy greens may stave off memory loss

MIAMI — Eating one serving of leafy greens per day may stave off memory loss in old age and keep the brain more youthful, according to research published on Wednesday.

The difference found between elderly people who ate greens and those who did not was stunning: the equivalent of being 11 years younger in age, said the study in the journal Neurology.

While the research was based on survey responses and therefore fell short of proving cause and effect, researchers said it offers further evidence of the association between healthy eating and healthy aging. 

“Adding a daily serving of green, leafy vegetables to your diet may be a simple way to foster your brain health,” said study author Martha Clare Morris of Rush University Medical Centre in Chicago.

The study tracked 960 people with an average age of 81, and followed them for an average of nearly five years. None had dementia upon entering the study.

Participants completed questionnaires that asked how often they ate certain foods, including spinach, kale, collard greens and lettuce. They also had their thinking and memory skills tested once a year.

People who ate the most greens averaged about 1.3 servings per day. Those on the opposite end of the spectrum ate 0.1 servings per day. A serving is about a half cup, cooked.

People who ate at least one serving daily “had a slower rate of decline on tests of memory and thinking skills than people who never or rarely ate these vegetables”, said the study.

These results persisted even after researchers accounted for factors like smoking, high blood pressure, obesity, education level and mental and physical exercise.

“These observations are consistent with a broader body of evidence suggesting that people adhering to a Mediterranean diet may reduce their risk of dementia,” said David Llewellyn, senior research fellow in clinical epidemiology at the University of Exeter, in England, who was not involved in the study.

One key aspect of the so-called Mediterranean diet is consuming plant-based foods, while limiting the intake of red meat. 

James Pickett, head of research at the Alzheimer’s Society in London, pointed out that “the researchers did not directly look at dementia, so we cannot say that it would delay or prevent the onset of the condition”.

“However, older people who ate one or two servings of Vitamin K-rich food per day performed better on memory tests than those who didn’t,” he added.

 

“A healthy diet rich in essential nutrients, combined with regular exercise and avoiding smoking, can help to reduce your risk of developing dementia.”

Ludwig W. Tamari: A life well lived, a man well loved

By - Dec 21,2017 - Last updated at Dec 21,2017

Ludwig W. Tamari (1927-2017) lived a full life.

In fact, he lived an exemplary life. His “modus vivende”, to borrow a term he loved, was always optimistic, empathetic and inclusive. 

Not once could you hear him utter a negative word about any living soul. He had a heart of gold and an accompanying intellect that was hard to match. “Blessed are the pure of heart”, says Matthew, “for they will see God” (Matthew, 5:8).

Surrounded by his loving family, Ludwig passed away at his home in Potomac, Maryland, on the night of December 7, 2017 at the age of 90. 

He is survived by his devoted wife of 52 years, Myr Tamari (born Hanania); children Wahbé, Rula and Marwan; children’s spouses Vanda, Omar and Nadine; and seven grandchildren. 

Thus ended a remarkable life lived to its fullest by an adventurous, cultured, resilient and indelibly tolerant man. 

Abu Wahbé, as he is lovingly known to his friends and family, was born in Jaffa, Palestine. His family members were Arab Christians of the Greek Orthodox sect. Ludwig was born in July 1927 during the interwar period when Palestine was still under a British mandate.

His mother, Adela Malak, hailed from a prominent Palestinian family. Having befriended a German nurse, Adela asked the nurse to name the newborn child. The nurse’s choice fell upon the name Ludwig, in honour of her brother. Ludwig is an old Germanic name, a composite of two words: “Hluth” meaning “famous”, and “Wig” denoting “war”. Many great men were so named, from Beethoven to Wittgenstein. 

Tamari was a lifelong pacifist, but he fought the good fight and succeeded in overcoming every trial and tribulation that life threw at him. In doing so, he lived up to the example of many of his namesakes.

“Waylunlil-maghlub” he sometimes wrote in his letters, a reference to the plight of the Palestinians. 

“Woe to the Vanquished!” 

He knew that plight full well.

A refugee from Palestine to Lebanon and Jordan, he became an exile a third time in America, due to the Lebanese Civil War and tough economic times in Jordan.

As if the protagonist in Thomas Cole’s famous paintings, “The Voyage of Life”, he took life by the horns and went wherever he needed to go to support his family, while all the while remaining a calm, strong, steady influence.

In short, he was a sturdy captain at the helm of a ship that had to cross the most turbulent waters.

Exiled from the shores of Jaffa by the Palestinian Nakba or catastrophe, his voyage took him to the urban environs of Beirut, to a then small, perhaps unpromising town of Amman in Jordan, and finally to Central and North America.

He encountered obstacles everywhere he went, but overcame every challenge.

Where others saw trouble, he saw opportunity.

As a creative, enterprising Christian Palestinian merchant in Lebanon and Jordan, he met with both support and opposition. As an émigré doing business in the United States, he understood that the path to integration and assimilation was not always smooth.

But like one of his namesakes, Ludwig Joseph Wittgenstein, Tamari understood that “the world is all that is the case”.

Politically, Tamari was a realistic moderate, although his realism was always undergirded by a deeply empathetic view of other human beings.

At a talk he gave at Cornell in 1956, Ludwig conveyed the typical fears of an exile living in America, but also expressed his unyielding confidence in the country’s democratic foundations: “America must be beyond reproach because she assumes the democratic leadership of the world,” he is quoted as saying by the Cornell Daily Sun. “Segregation in this country must not be compared with segregation in other countries, but America should be above them.”

His belief in America’s strength was reflected in a sound, but brave, decision to buy what was then an inconspicuous piece of land in Potomac from a farmer during a random drive through the wilderness of Washington, DC. Atop that land now sits his family’s home in one of the most prestigious locales in the world.

His “Lebensphilosophie”, or philosophy of life, was forward-looking. He took calculated and sometimes spontaneous risks and, more often than not, reaped the rewards of doing so.

Perhaps he had inherited this trait from his father, Wahbé Tamari, a successful Palestinian merchant.

Wahbé had been educated in Jesuit schools during the Ottoman period and eventually built a profitable citrus growing company and worked as a trader. He was also a philanthropist who contributed time and money to educational ventures and charities.

Together Wahbé and Adela raised six children: Abdallah, Joseph, Ludwig, Nina, Diana and Farah. 

After receiving his primary and secondary education in Palestine, Ludwig attended the American University of Beirut in the 1940s and received an MBA from Cornell University in 1956.

Ludwig left Palestine with his family on May 15, 1948, the day the British mandate of Palestine ended. He moved to Amman with his youngest brother Farah. As a result of their combined efforts, the Tamari family business experienced significant growth. Through hard work and business acumen, the two brothers emerged as leading industrialists and traders in Jordan. They successfully imported and exported foodstuffs and raw materials such as sugar, rice, coffee, tea and vegetable oils. 

Like their father, the two Tamari sons were diligent businessmen who had a long-term vision predicated on a sound understanding of regional politics and dynamics. The Tamaris bought land in the early 1950s in Marka and constructed a flourmill, banking on the expectation that Amman was a burgeoning city at the time where there would be a growing need for food. They then established a tea-packing plant and a facility that produced vegetable oils, again anticipating a rise in consumer demand for such products. The Tamaris also understood that Palestinian markets in the West Bank would naturally be cooperating with East Bank Jordanian markets in this newly evolving business environment. They cultivated strong relationships with the authorities in Jordan and with leading business minds throughout the region. 

By the 1960s, the Tamaris were firmly established as major industrialists and traders. They soon diversified in the area of light industries, which included packaging. The family business continued to grow despite the challenges posed by the 1967 Arab-Israeli War and the 1975-1990 Lebanese Civil War. Eventually, Ludwig and Farah established the Tamari Trade and Industry Company, which exported sugar, food, vegetable oils and spices to Iraq.

During the 1980s, Ludwig moved to the United States and settled with his family in the small, scenic town of Potomac near the fabled Potomac River in Maryland. He continued to travel to the Middle East but also cultivated business ties in Honduras and Guatemala, trading coffee and cardamom. 

In addition to his knack for business, Tamari was a scholar, activist and philanthropist. He wrote and published many articles in Arabic and English about the politics and history of the Middle East, anticipating some of the major developments that were to beset the region. Tamari knew and interacted with most of the key players in the Middle East, including many of the leaders of the region. He was moderate and always espoused reconciliation. 

Although a Christian by birth, Tamari was well-versed in the Koran and in the Islamic tradition more broadly. His command of both English and Arabic was superior and reflected years of reading and learning. He could quote verses from the Muslim holy book and from the Hadith at will to explain or elaborate a particular point. He was also erudite in the areas of Western philosophy, antiquity, the histories and cultures of the indigenous peoples of the Americas, and in the history of Arab-Jewish relations.

Ludwig’s political views mirrored his views on life.

Among his many writings, Ludwig published a beautifully written article titled “The Declaration of Principles: Shock Treatment for Palestinians and Israelis” in Middle East Insight in 1993.

Rereading this prescient piece today in 2017, I recall a time when there was an active push for peace by men of his stature. The article calls for genuine efforts towards peace but warns that the journey could be easily set off-course by the wrong people. In concluding his article, Tamari exclaimed that “a tiny gesture of good will could arrest a flow of ill will” and called for courageous actions to build peace: “Let those with the will to give peace a chance, take that chance.”

Still Tamari understood the limiting nature of the peace process and the continued objectification of the Palestinians that it entailed. In a letter he sent me in 2005, he wrote that “now we are relegated from [the false claim of being] terrorists on the loose to the status of partners under the noose.”

He pieced together writings as if putting together a jigsaw puzzle, gradually collecting different clippings from newspapers and from his diaries, and pasting them on a single sheet of paper. From there, he would begin to write his essays. The end results were beautiful pieces that offered unique insights into Israeli-Palestinian politics and to the condition of the Arabs more generally. The pieces were teeming with important information and keen philosophical insights. They always displayed a broad understanding of what is going on in the region.

For our extended family, he was the primary starting point for any and all complex historical topics. You would start with him and he would guide you in the right direction. For me personally, he was absolutely instrumental in my growth as a human being and as a scholar.

Both my older brother Zeid and I followed in his footsteps by going to Cornell University, which is the best academic decision we took. In an uncanny coincidence, Zeid rented a room in the same house that Ludwig had occupied in Ithaca, NY, some 42 years earlier. After renting the room, Zeid stumbled upon a ledger that contained the names of all of the house’s prior occupants. When he got to the 1950s, he found the name Ludwig W. Tamari.

Together with his wife Myr, and throughout his life, Tamari was active in prominent circles to try to promote peace and reconciliation in the Middle East.

The couple also shared a passion for helping other people and opened their home to various charity organisations.

With their family, they patronised the Wahbé Tamari Kindergarten in Amman which, since 1973, has espoused a modern philosophy to develop the holistic capabilities of children. 

Ludwig also provided scholarships to gifted students as they made their way through school and university. He helped everyone who came his way from a driver who was going through hard times to the employees of the Tamari Company, and even to lending the famed author Alfred Lilienthal his cabin in Lebanon so that the writer could have the solitude he needed to write one of his most famous works.

Ludwig was a strong, physically resilient man. He loved the outdoors and nature. As if sensing the kindness of this larger-than-life person, animals warmed to him and, as a consequence, the family kept pets for many years.

Abu Wahbé often spent hours doing hard laborious tasks outside his home in Maryland.

Well into his late 80s, he was still strong enough to shovel mounds of snow off his property. He also was an amateur artist and excelled in water painting, a passion he shared with Myr. Their beautiful paintings adorn the walls of their home in Potomac, in addition to works of indigenous art from all over North and Central America that Ludwig collected over many years.

 

Tamari lived a peaceful, productive, exemplary life. He died peacefully and will be missed.

Rich people experience happiness in more self-centred way

Rich people are different from the rest of us — and that includes the way they experience happiness.

Instead of feeling positive emotions that involve connections with other people, their happiness is more likely to be expressed as feelings that focus on themselves, new research shows.

However, this difference does not necessarily mean that high-income people have more total happiness than people who earn less.

The findings were published this week in the journal Emotion, and they seemed to fit a larger pattern, according to the psychologists who conducted the study.

After all, they wrote, people with money are more insulated from social and environmental threats. That gives them the luxury of being able to focus on their own “internal states and goals” instead of having to worry about other people.

Those who inhabit the lower classes, on the other hand, often find themselves at the mercy of others. They may be more vulnerable to crime, for instance, or may be forced to send their children to underfunded schools. In their case, the researchers wrote, the best coping strategy is to muddle through together. That requires them to focus on other people instead of just themselves.

To see how social class influences happiness, Paul Piff and Jake Moskowitz of UC Irvine examined survey data from 1,519 Americans who answered questions about their household income and their emotional state. The participants hailed from all 50 states, and they were a racially, ethnically and economically representative microcosm of the country as a whole.

The survey probed people’s happiness by asking about seven distinct positive emotions: amusement, awe, compassion, contentment, enthusiasm, love and pride. Each emotion was described in a concise sentence, and survey-takers used a seven-point scale to show how much they agreed or disagreed with the statement.

The researchers found that people from higher social classes were more likely than their poorer counterparts to agree with statements indicating they felt pride (“It feels good to know that people look up to me”), contentment (“I feel satisfied more often than most people”) and amusement (“Many things are funny to me”).

On the other hand, people with less money were more likely than their richer counterparts to agree with statements that indicated compassion (“Nurturing others gives me a warm feeling inside”), love (“I develop strong emotions towards people I can rely on”) and awe (“I often feel awe”).

These associations held up even when the study authors controlled for factors including age, gender, political ideology and religious beliefs, the researchers reported.

The only aspect of happiness unaffected by income was enthusiasm, which the researchers assessed with the sentence, “I get great pleasure from pursuing my goals.”

“These findings indicate that wealth is not unequivocally associated with happiness,” Piff said in a statement.

 

“What seems to be the case is that your wealth predisposes you to different kinds of happiness,” he explained. “While wealthier individuals may find greater positivity in their accomplishments, status and individual achievements, less wealthy individuals seem to find more positivity and happiness in their relationships, their ability to care for and connect with others.”

Mirrorless digital cameras, more computers than ever

By - Dec 21,2017 - Last updated at Dec 21,2017

High-end dedicated mirrorless cameras are the latest trend in digital technology in general, and in digital photography in particular. What do they bring to the consumer, and what is really a mirrorless camera? 

With Sony in the lead, followed by big names like Panasonic, Leica and Fujifilm, most famous makers are producing what is expected to replace more traditional models, those with a mirror. Even Nikon, for a while reluctant to follow the trend, and adamant to stick to its well-known technology, has jumped on the bandwagon and has come up with a mirrorless model.

By ditching the mirror, manufacturers are bringing high-end digital cameras one step closer to being full computers in their own right.

The mirror in a DSLR camera is here to let the photographer view the image directly and optically, through the lens all the way to the viewfinder, without any digital element interfering in the way. When the shutter is actioned, to take the picture, the mirror flips up, mechanically, to let the image go to the digital sensor, to be captured, stored and then processed digitally.

Despite the invaluable advantage of being able to view the image optically thanks to the mirror, the system has a few major drawbacks. It makes the cameras bigger and heavier, it produces a little “shake” when it flips up, and it is noisy.

Hence the trend to try and remove the mirror, while still designing high-end, dedicated cameras. With a mirrorless system the photographer previews the image electronically, not optically. Therefore the quality of the previewing depends on the quality of the electronics generating it.

Is mirrorless a new discovery? Of course not! Already all cameras in smartphones are mirrorless, understandably. They have no viewfinders and we preview the image we want to shoot electronically on the phone’s screen. What is new is having mirrorless in professional and semi-pro cameras.

Mirrorless in high-end models is meant to provide the best of both worlds: firstly quality and comfort in previewing the image electronically, which is hardly there in smartphones or entry-level dedicated cameras, and secondly the essential need to use full-size, interchangeable lenses, the sum of it all leading to great photos, artistically and technically.

It is essentially the continuous progress in chips and computers processing speed and the possibility to have gigantic digital memory storage in a very little space that has allowed the big cameras manufacturers to achieve the trick. And as with any innovation that tries to steer away from the traditional, a large number of professional photographers still only swear by mirror cameras.

On the other hand, and as an example, pro photographers who shoot during classical concerts have long awaited the advent of high-end mirrorless cameras. For them quiet shooting is of prime importance. They hate to disturb musicians with the noise of their camera’s mirror flipping up, during a pianissimo passage — well, to be precise it is rather the musicians who hate to be disturbed this way!

 

As usual, sophistication comes at a price. From the “humble” and newcomer Nikon 1J5 at $500, to the already popular Sony Alpha a7R III at $3,000 and all the way up to the elitist Hasselblad X1D-50c, which is a mere $8,000 (body only…), none of these models is cheap. And you thought your smartphone was expensive?

Mistaken identity

By - Dec 20,2017 - Last updated at Dec 20,2017

For no apparent fault of his, last week, my husband got mistaken for the US ambassador to Mauritius. Though I realised it was a blunder, I did not make the effort of correcting it immediately. I mean, as new inhabitants in a foreign country, it did not hurt to acquire some special privileges, even if they were given by default.

Moreover, I quite liked the idea of being the wife of a diplomat. It had more substance to it, though the nation we were supposedly representing was not the flavour of the season, so to speak. Especially after Mr Trump opened a Pandora’s box with his Jerusalem decision, breaking with decades of American and international policy and defying dire worldwide warnings. It was scary to contemplate how much spin doctoring his envoys would have to do in the coming months.

Meanwhile, I refrained from telling the voice on the phone that His Excellency was, in fact, not His Excellency at all. One more reason was that after my calling the Mauritius Telecom offices repeatedly over the last several days, this was the first time they had called me back, and it took me a split second to get over the unexpected turn of events. I had been chasing them to get the fibre optic cable connection installed for the Internet so that I could link up with the rest of the world but during each call, I was made to wait for long periods, listening to the robotic instructions on a loop, before anyone would answer. They spoke to me in French, Creole and finally English, when they figured that I could not understand a word of the earlier two and assured me that they would send someone over to the house soon. Needless to say, I waited in vain as no one turned up.

So when the voice on the phone asked if it was the house of the American ambassador I dropped the receiver in surprise. Collecting my wits, I mumbled a response, which was also incoherent to my own ears. I think they took it as an affirmation because the effect was like the proverbial grease lightening. The woman’s tone became friendliness personified as she apologised for the delay in service. She said that His Excellency’s request would immediately be put on fast track, which she would be monitoring everyday, and a team of people would be deployed so that the installation gets done smoothly, in the shortest possible time.

I was literally and figuratively dumb struck because I had never witnessed such a U-turn in my life. The voice at the other end took my silence as a sign of displeasure and kept imploring for my forgiveness. Belatedly I realised that I had to say something; my conscience urged me to come out with the truth though my head said I should carry on with the deception till the job was completed. But before I could decide, the line got disconnected.

The mechanics arrived to my house the very next day.

“Why is everybody behaving strangely?” my husband questioned. 

“What do you mean?” I pretended ignorance.

“They think this is the house of the US ambassador,” he stated.

“Please keep up the charade,” I whispered. 

“That is impossible,” he said.

“Why? You are diplomatic enough,” I mumbled. 

“But you are not,” he responded. 

“What have I got to do with it?” I asked. 

“Their new envoy happens to be a lady,” he laughed.

Traffic pollution tied to low birth-weight risk

NEW YORK — Air pollution, but not traffic noise, appears to be linked to an increased risk of having low-birth-weight babies, reports a new study from the UK. 

Previous studies have tied road traffic air pollution to low birth weight. Road traffic produces noise as well as pollution, but studies of noise pollution have had conflicting results, say the authors. 

“We know that noise is associated with adverse health effects, e.g. sleep disruption, increased blood pressure, and cardiovascular disease, so it could plausibly have an impact on mothers’ health in pregnancy and the health of unborn babies,” study leader Dr Rachel Smith Smith at the School of Public Health of the Imperial College in London told Reuters Health in an e-mail. 

Smith’s team wanted to investigate the effect of exposures to both traffic-related air and noise pollution during pregnancy on babies’ birth weight. 

“We found increased risk of babies being born with low birth weight or small for gestational age, at term, to mothers with higher exposure to air pollution from road traffic during pregnancy. We did not see an independent effect of road traffic noise on birth weight,” she said. 

As reported in The BMJ, Smith and colleagues used national birth registers to identify over 540,000 live, single, full-term births occurring in the Greater London area between 2006 and 2010. Specifically, the study team was interested in low birth weight (less than 2.5kg) and being born small for gestational age. 

Mothers’ home addresses at the time of birth were used to estimate the average monthly exposure to traffic-related pollutants including nitrogen dioxide, nitrogen oxides, and fine particulate matter, or PM2.5. The researchers also estimated average day and night-time road traffic noise levels. 

Increases in traffic-related air pollutants, especially PM2.5, were associated with 2 to 6 per cent increased odds of having a low birth weight baby,  and about 1 to 3 per cent increased odds of a baby being small for gestational age, even after taking road traffic noise into account. 

The risk associated with air pollution should be considered in context, i.e. the size of the effect of air pollution on an individual baby’s birth weight is relatively small compared to the well-recognised effect of smoking, said Smith. 

“However, at the population level the impact could be large, because collectively more women are exposed to air pollution than are exposed to smoking during pregnancy,” she said. 

There is a limit to what individuals can do to reduce their exposure to air pollution because making major changes to lifestyle, travel or where they live is just not feasible for the vast majority of people. Improving air quality and reducing air pollution in our towns and cities, and thus reducing health impacts of air pollution, requires action by policymakers, said Smith. 

The study “should increase awareness that prenatal exposure to small particle air pollution is detrimental to the unborn child”, Sarah Stock and her colleague wrote in an editorial in The BMJ. 

Stock, a researcher at the University of Edinburgh Queen’s Medical Research Institute in Edinburgh, UK, said air pollution from traffic is well known to be detrimental to child and adult health. 

“This study provides further evidence that air pollution from traffic is also harmful to unborn babies. However, it shows that traffic noise is unlikely to be related to low birth weight in babies,” Stock, who was not involved in the study said. 

Pollution should be high on agendas at a local and national level, with pollution control integrated into development planning, said Stock. 

“Key initiatives include enforcing emission control technologies in motor vehicles; ensuring easy access to affordable and efficient public transport; encouraging walking and cycling; and mandating clean air zones,” she said. 

Unfortunately, women have few options to reduce their risk on a personal level, said Stock. 

 

“Avoiding air pollution is difficult, and we have no evidence that lifestyle measures, or wearing protective masks actually reduces chronic exposure to harmful pollutants. We do know avoiding exposure to tobacco smoke is really important. More research in this area is needed to find out the best ways for women to reduce their risk,” she said. 

Brain cells develop more mutations as we age

Brain cells — neurons — develop gene mutations over the course of a lifetime, contributing to normal aging and potentially presenting a target for treatments that stave off dementia and other types of cognitive decline, researchers say. 

The team developed a way to sequence the genomes of individual neurons, which allowed them to see what changes are normal and also what happens in specific brain diseases. 

”The work is at a very early stage,” senior study author Dr Christopher A. Walsh from Harvard Medical School in Boston told Reuters Health by e-mail. “We have only just developed a method that we hope will give us new insight into how neurons age, and we hope to use it to understand more about common forms of dementia and degeneration.” 

Scientists have long thought that aging and degenerative brain diseases are associated with genetic changes in brain cells, but until now, they have not had the technology to test this theory. 

Walsh’s team found a way to look at all the genes within a single neuron and then analysed neurons from the cadavers of 15 neurologically normal individuals aged 4 months to 82 years. The also looked at nine people diagnosed with Cockayne syndrome (CS) or Xeroderma pigmentosum (XP), conditions caused by defects in DNA damage repair that are associated with brain degeneration and premature aging. 

Just like cells throughout the rest of the body, the researchers found that genetic mutations increased in number with increasing age in normal neurons. But, they noted, brain regions associated with age-related degenerative conditions like Alzheimer’s disease and age-related cognitive decline were especially affected, according to the report in the journal Science. 

Autopsy specimens from brains of patients with CS and XP also showed increased numbers of mutations, which were more than twice as common as those seen in brain cells from individuals of the same age without those diseases. 

The researchers found that mutations start occurring even as the brain is still developing in an infant, and they estimate that by the age of 1 year, normal brain cells have 600 to 900 single-letter changes in their genes. By the time someone is in their 80s, there are an estimated 2,400 changes. 

The study team also identified three patterns of mutations in brain cells across a lifetime. In one, which they called Signature A, mutations increased with age regardless of brain region. In another, which they called Signature B, mutations were increased in brain regions associated with Alzheimer’s disease, but not in areas associated with age-related cognitive decline. 

The third pattern, Signature C, showed a different class of genetic mutations that are characteristic of oxidative damage, and were most common in patients with CS and XP but also increased with age in normal neurons. 

The researchers summarised this accumulation of genetic mutations, a form of cellular senescence, in a single term: genosenium (aging of the genome). 

“I found it surprising not just that the number of mutations increases with age, which we sort of expected to see [though we did not know how, or how fast, they would accumulate], but that some types of mutations accumulate with age [Signature A], and other biochemically distinct types of mutations [Signature B] are present at birth and don‘t’ accumulate with age at all,” Dr Walsh said. 

“To be able to have the precision to dissect out these different types of mutations was more than we could have hoped for,” he added. “We also find that different people may accumulate mutations at different rates, and we need to know what might control that.” 

”I was surprised to see the quite clear correlation of somatic mutations with age using a relatively small number of neurons,” said Dr Sarah E. Harris, a specialist in genetics at the University of Edinburgh Centre for Cognitive Aging and Cognitive Epidemiology in the UK, who was not involved in the study. 

 

“As a geneticist interested in determining genetic influences on cognitive ageing, it’s fantastic to see the technique of single-cell whole-genome sequencing being used to identify mutations in the brain that are acquired during the life-course,” she told Reuters Health by e-mail. 

Nissan Kicks: Keen compact crossover

Launched last year and rolled out in various American, Asian and Middle Eastern markets since, the Brazilian-built Nissan Kicks is a practical and fun driving crossover. A particularly good value proposition in more basic specifications, the Kicks is set to replace both Nissan’s smaller Juke and larger Qashqai crossovers in certain markets. Starting from JD17,900 and retailing at JD23,900 on-the-road, as driven in SL guise, the Kicks is available with three trim levels regionally and a sole engine and gearbox option.

 

Urban ability

 

If not quite as adventurously leftfield in design, as its Juke stablemate, the Kicks is nevertheless quite the eye-catching and unconventional design on its own merit. Available only with front-wheel-drive, the compact Kicks’ muscular design, however, lends it a bigger sense of presence, and features sharp complex lines and defined and ridged surfacing. With Nissan’s trademark V-motion grille and boomerang rear light design, the Kicks also features optional two tone paint and blacked out pillars for a distinctive floating roofline effect.

Comparable in size and drivability to a C-segment hatchback, but with an SUV-like flavour, the Kicks is an ideal urban crossover that is efficient and easy to park and manoeuvre. With generous 200mm ground clearance and 20.6° approach and 

28.4° departure angles it dispatches a developing city’s bumps, lumps and cracks in a comfortable stride. Cabin headroom is meanwhile generous in front and better than average in the rear and width decent, if not huge, while minimum uniformly shaped 432-litre luggage volume good.

 

Progressive pace

 

Powered by a naturally-aspirated 1.6-litre four-cylinder developing 118BHP at somewhere between 5,500-6,000rpm and 110lb/ft at around 4,000rpm, the Kicks’ engine is progressive in delivery and just right in refinement and sound insulation, without being too distant. As responsive from idle and versatile in mid-range as it needs to be for keeping a good pace, the Kicks accelerates through 0-100km/h in 11.5-seconds, and returns both a good headline combined fuel consumption rating of 6.1l/100km, and is frugal in real world driving.

A perky engine that is happy to rev high in its own right, the Kicks’ 1.6 can, however, initially seem unwilling to rev all the way to 6,000rpm, owing to its continuously variable transmission. Ultra smooth and efficient in normal driving, CVT does however prefer to keep a car in its more efficient low and mid speed rev range, and is not as clear cut in changing ratios when more power is needed. However, Nissan’s CVT is one of the better ones there are.

 

Fun and flickable

 

Seemingly “learning” and adapting its ratio shift algorithm to ones driving style after a short drive, the Kicks’ throttle becomes more responsive as more aggressive. With lower ratios called up more often and held for longer periods of time to allow the engine to rev more freely to just past 6,000rpm, the Kicks’ sportier transmission profile better handles inclines and suits its sporty driving, but one would still have preferred the Latin American spec manual gearbox option. Meanwhile front disc and rear drum brakes proved reassuringly effective even on steep descents. 

Despite high ground clearance and aggressive SUV-like design, the Kicks is true to its hatchback-like underpinnings and size in the way it handles with eager agility and manoeuvrability. Fun and frisky through narrow winding roads, the Kicks’ electric-assisted steering is direct, quick and precise yet refined and stable at speed. Flickable and crisp on turn-in, the Kicks’ steering provides decent feel owing to comparatively slim 205/55R17 tyres. Meanwhile, front grip is assured, with understeer apparent only if pushed too fast and tight into a corner.

 

Agility and adjustability

 

Riding on front strut and rear torsion beam suspension and weighing in at just 1,135kg, as driven, the Kicks is nippy, tidy and keen to adjust a cornering line on throttle or to pivot weight with a dab of the brakes. Though riding high, it feels nimble and alert, while damping is taut and provides good rebound control. Finding a happy medium between firmness and comfort, it well-controls body lean through corners but rides forgivingly if slightly busy over imperfections and smoothly at speed.

 

Well-packaged and accommodating, the Kicks could have freed up more space if the centre console were removed. Stylish and ergonomic with sporty flat-bottom steering wheel, it features soft textures prominently, while some hard plastics for affordability. Driving position is alert, upright, supportive and with good road visibility, while a clear instrument cluster features an analogue speedometer and configurable digital pod for rev counter and other information. Driven in well-equipped top SL spec, the Kicks features a rear and around view monitor with Moving Object Detection.

‘Childhood obesity climbing with media use’

By - Dec 18,2017 - Last updated at Dec 18,2017

Children’s waistlines have been expanding in lock step with the amount of time they spend with televisions, computers, smartphones and tablets, European doctors say. 

In the past 25 years, obesity rates have climbed rapidly among European children and teens, according to a consensus statement from the European Academy of Paediatrics and the European Childhood Obesity Group published in Acta Paediatrica. 

Roughly one in five kids and teens in Europe are overweight or obese, according to a 2017 World Health Organisation study, the authors note. 

Today, 97 per cent of European households have a TV in their home, 72 per cent have a computer, 68 per cent have Internet access and 91 per cent have mobile phones, according to the statement. 

This has spurred a surge in screen time, contributing to inadequate sleep, worse eating habits and less exercise — all of which can make it easy for children to become overweight, the statement authors argue. 

“Mass media has been shown to have a broad effect on children’s health and can affect them physiologically and have an impact on their socio-cultural functioning and psychological well-being,” said senior author of the statement, Dr Adamos Hadjipanayis, a researcher at European University Cyprus in Nicosia and secretary general of the European Academy of Paediatrics. 

“There is evidence of a strong link between obesity levels across European countries and childhood media exposure,” Hadjipanayis said by e-mail. 

Parents are part of the problem, Hadjipanayis and colleagues argue. 

Even as children’s screen time rises, parents demonstrate little awareness about what their kids do online or how much time they spend with tablets, smartphones and computers, the statement emphasises. 

Food advertising is another problem, because it can convince kids to crave and demand more junk food and make them less likely to eat their fruits and veggies, the statement also notes. Kids also tend to consume a large portion of their daily calories while watching TV, when ads may influence their food choices. 

The fix is more vigilance, the authors argue. 

“When their TV time goes down, so does their [weight],” said Dr David Hill, chair, American Academy of Paediatrics (AAP) Council on Communications and Media and a researcher at the University of North Carolina School of Medicine in Chapel Hill. 

“Food advertising seems to drive this relationship, as opposed to decreased activity. Sleep is also a major concern,” Hill, who was not involved in the statement, said by e-mail. “Screen media before bedtime interfere with sleep quality and duration, and poor sleep contributes to obesity.” 

The APP has tips for parents on managing media online, Hill said. 

Common sense should prevail, said Dr Jennifer Emond, a researcher at the Geisel School of Medicine at Dartmouth College in Lebanon, New Hampshire, who wasn’t involved in the statement. 

“Limit media time each day, no media in the bedroom and ensure the media children are exposed to is high quality,” Emond said by e-mail. “Regarding social media, parents should have access to their children’s social media sites and monitor their children’s interaction with social media — that has benefits beyond promoting a healthy weight.” 

Parents of children who are already spending hours a day online and watching various screens may want to cut back media use gradually to make changes more effective, said Erica Kenney, a researcher at the Harvard T.H. Chan School of Public Health in Boston who was not involved in the statement. 

 

“If parents find that their kids are using media for something like seven hours a day or more, which seems pretty typical... trying all of a sudden to get that down to two hours a day is probably not going to be successful,” Kenney said by e-mail.
