FEATURE-Syria grapples with surging population

DAMASCUS, June 3 (Reuters) – Ibrahim Issa, a jovial Syrian taxi-driver who wears a blue robe over an ample belly, has nine children from two wives. He plans to marry a third wife soon.

He says it is up to Allah whether more children arrive, and not for him to interfere, say, by using contraception. Like all Damascus taxi-drivers, he complains about the cost of living and how hard it is to make ends meet on the $300 a month he earns.

Issa, 43, shrugs when asked if all those mouths to feed don’t make life harder for him. “No, I’m delighted,” he grins.

Syria now has a population of 20 million people, with a growth rate that remains one of the world’s highest at about 2.4 percent. But it has declined since averaging 3.2 percent from 1947-94, according to the Syrian Commission for Family Affairs.

“We have a population problem, no question,” said Nabil Sukkar, a Syrian economist formerly with the World Bank. “Unless we cope with it, it could be a burden on our development.”

He said labour supply was growing about 4.5 percent a year, due to rapid population expansion in earlier decades, outpacing the capacity of Syria’s economy to create jobs for the quarter of a million youngsters arriving on the job market every year.

“Too big a population means a high burden on government services, such as education, electricity and health care,” he said. “Perhaps in 20 years the growth rate will go down to 1.5 percent as in Egypt, but in the meantime we do have a problem.”

The official unemployment rate is around 10 percent, but independent estimates put it at anywhere up to 25 percent.

DISPARATE FERTILITY RATES

Syrian women have an average of 3.6 children each, but this masks big disparities between cities and the countryside.

Despite the efforts of men like Issa the taxi-driver, fertility rates in Damascus and three other governorates are set to fall from 2 to 2.5 children per woman now to 1.4 to 2 by 2025, below the replacement rate of 2.1 children per woman.

In the seven least-developed of Syria’s 14 governorates, women have between 3.8 and 6.2 children. Their fertility rates are not expected to decline much in the next 15 years.

Demographers say urbanisation and the spread of education, especially among girls and women, are among the most potent forces that eventually curb population growth across the world.

Syria’s minority Christians, who tend to be well-educated citydwellers with high aspirations, provide a good example.

“My grandfather had eight children, my father had four and I have only two,” said Samer Lahham, who runs ecumenical affairs at the Greek Orthodox Patriarchate in the Syrian capital.

“Now maybe after five years each family will have only one because of economic problems, education costs, living costs.”

Religion as such is irrelevant, said Lebanese demographer Riad Tabbarah. “Development brings education, which is a crucial factor because it increases the cost of raising children. Once education and modernisation set in, fertility falls.”

Syria, only now emerging from a socialist-style command economy, has modernised more slowly than nearby Lebanon, where fertility is already below the replacement rate and where the Lebanese have long yearned for lifestyles beyond their means.

“What affects fertility is also the difference between your income and your conventional standard,” Tabbarah said.

Contact with the outside world often gives people a taste for cars or other goods they can only afford by having fewer children, he said. “In Syria, that exposure came slowly and they still have a high fertility level, but it’s coming down.”

COMMUNICATION REVOLUTION

The aspirations of Syrians, like Arabs elsewhere, are now rising because of satellite TV, mobile phones and the Internet. “Young citizens are likely to have greater expectations than their parents, with readier access to regional and international media,” a Western diplomat said. “Even remote villages have satellite dishes. Many Syrians work abroad and return.”

Youngsters may be delaying marriage in places like Damascus, partly because they spend years in higher education and partly because they then cannot meet the traditional marriage costs.

A 32-year-old philosophy graduate said he was still single and lived with his parents because he could not afford the apartment that any bride would demand, even though he drives a taxi to supplement what he makes working at a government clinic.

“There are so many like me,” said the frustrated young man, refusing to be named. “It’s enough to drive people to crime.”

In rural areas, families are often large because it is relatively cheap to raise children until they are nine or 10 and can start working in the fields or earning money elsewhere.

Until modernisation prompts people who lack knowledge or access to contraceptives to desire fewer children, family planning advice is likely to fall on deaf ears. “Before that, nobody wants it. After that, nobody needs it,” Tabbarah said.

Giving girls a chance to go to school is a vital element in tackling Syria’s population challenges, said Etab Altaqee at the U.N. Population Fund, which works with the Syrian government.

Altaqee said some community-level efforts in the northeast had yielded small but encouraging results.

“In one of the poorest villages, the girls were saying we want to continue our education, but we need a bus because our fathers won’t allow us to go to school by ourselves,” she said. “It was as easy as that, just to provide them with transport.” (Editing by Samia Nakhoul)

Karnataka devotees pierce their bodies to worship goddess

Davangere (Karnataka), May 11 (ANI): Devotees of the Goddess Mattu Mariamma in Karnataka”s Davangere town pierce their bodies with iron nails in an act of worship and to seek her blessings.

They pierce various parts of their bodies, including their tongues, backs, chests and cheeks.

“Some people don”t have children and some people have difficulties at their homes, and to overcome these difficulties, we follow this ritual every year and pierce our bodies,” said Meenakshi, a devotee.

Many childless devotees pierce their bodies in the belief that the goddess would grant them children.

“People worship Mattu Mariamma if they don”t have children, if they have some disease, if girls don”t get married,” said Lakshman, another devotee.

Some devotees go as far as putting tridents in their mouths or hanging iron hooks from their backs as a mark of worship of Mattu Mariamma.

Devotees even hang heavy weights from their bodies in the belief that their wishes would be fulfilled. (ANI)

Six steps to a happy sex life

London, Apr 30 (ANI): Feeling shy to make that first move in the bedroom? Well, here are six sex tips to get you all raring to go and sweep your man off his feet.

1. Bag Some Bedroom Magic with Before-Play

No surprise that women blame a lack of romance for a lack of sex! Time to nurture “before-play” between you—if you”ve had a row, or are stressed after work, let him know you need some cuddles and affection.

Don”t expect him to be a mind reader – men aren”t good at that. Ask him for a compliment, too. Men respond to straight talking so tell him that feeling appreciated and loved-up gets you in the mood for proper foreplay, reports The Sun.

Having before-play creates the right mood to get turned on. So include things like always having mood music ready to play, and candles to light your supper – even if it”s a takeaway!

2. Get Steamy!

Time to turn up the heat. Why not suggest having a candlelit bath or sexy shower together. Subtle candlelight flatters your figure! Take time lathering each other up with some sexy-scented shower gel. Have a couple warm towels ready to dry each other off before you tumble into bed.

When you indulge each other in steamy little pleasures it”ll give you loads of ideas for more sensual tricks to tempt each other into bed. You could offer to wash his hair and caress his scalp gently. Show him a light touch and then ask him to return the favour.

Once you”re out of the shower dare him to paint your fingernails. As he strokes each of your fingers gently it produces the love hormone oxytocin in your bodies.

3. Get Rude with Food!

It”s crucial to make sex as easy-as-can-be when you”re a busy/tired couple. So grab opportunities like getting a bit rude with food together. It”s super sexy to hand-feed each other little tidbits or to spoon something delicious like chocolate mousse into each other”s mouths.

Or why not have a rude-food feast in bed on a Saturday afternoon? Who says you have to eat at the table! This is the perfect setting for drizzling some sweet honey down your cleavage for him to lick off – forget about putting it on toast!

4. Letting Him Know What You Want

Believe me he wants to know what turns you on! If you”re feeling a bit shy then show him rather than tell him what to do. Take his hand and guide it gently around your pleasure-zones. Pause where it feels fab saying, “I love it when you touch me here.”

Also when he happens to touch you just right “big him up” – men love praise so heap it on him and he”ll do more of that feel-good foreplay.

If he”s a bit heavy-handed (true of so many men!) use this trick— take his finger and gently suck and lick it – then tell him that”s the sort of pressure you love.

And definitely use a warm and sensual voice to encourage him. Crikey, even just hearing your little sex-sighs will make him all ears! So use those little sighs and moans to communicate your pleasure.

5. How To Find Out What He Wants!

He might be a bit shy to tell you what he likes. So ask, ask and ask again! A good way to ask is to give him some options. Say something like, “do you prefer it when I stroke or squeeze you here, and more gently or firmly?” This”ll give him the confidence to be honest.

If he needs extra encouragement tell him you find it exciting being told what to do. Turn this into a playful sex-game where he”s the boss and you”re his sexy PA and he”s going to dictate to you what he wants done!

6. Your Private Pleasure Pack

Definitely make your sex-life simpler by keeping a little “pleasure pack” in your bedside table. Then when the mood strikes you”ll be ready for some frolics with your fella.

No annoying searching about for things like your favourite lubricant, condoms, sex toys, blind fold for a kinky sex game, sexy stockings and silky knickers, tissues, massage oils, etc. (ANI)

Energy drinks start their kick as soon as they touch your tongue

London, Apr 30 (ANI): Energy drinks starting their “kick work” as soon as they touch your tongue, concludes a new study.

In the study, Nicholas Gant at the University of Auckland in New Zealand and team had 16 participants tire out their biceps by flexing them for 11 minutes before rinsing their mouths with either a carbohydrate drink or a non-calorific, taste-matched one.

“One second after rinsing, the team applied transcranial magnetic stimulation to the participants” scalps, which aided the detection of activity in the motor cortex, a brain area known to send signals to biceps.

“The team found that the volunteers who swilled with carbohydrates were able to flex with more force immediately afterwards, and had a 30 per cent stronger neural response compared with those given placebo,” reports New Scientist.

The study has been published in Brain Research. (ANI)

Shisha ”as bad as ciggies”

Kuala Lumpur, April 27 (ANI): Smoking a shisha pipe is as harmful as smoking tobacco, according to a new research.

People who smoke shisha, or herbal tobacco, can suffer from high carbon monoxide levels, the Department of Health and the Tobacco Control Collaborating Centre has found, Qatar News Agency (QNA) has reported.

High levels of carbon monoxide can cause brain damage and unconsciousness.

Shisha is a water-pipe in which fruit-scented tobacco is burnt using coal, passed through an ornate water vessel and inhaled through a hose.

The research revealed that one session of smoking shisha resulted in carbon monoxide levels at least four to five times higher than the amount produced by one cigarette.

Dr Hilary Wareing, director of the Tobacco Control Collaborating Centre, told the BBC”s Asian Network that the results of the research shocked her.

“Our mouths opened at the level of harm – none of the tests we did showed anything other than shisha is hazardous to health,” New Straits Times Online quoted her as saying. (ANI)

Ceremony looks to boost river flows

The River Country Spirit ceremony is making its way along the Darling and Murray rivers, to dance back the spirit of the river and country.

The Indigenous Ngarrindjeri people of the rivers will be at Crick Park in Menindee tonight, after performing a ceremony in Wilcannia last night.

The ceremony is aimed at restoring the environmental flows in the river system, because the lower lakes, Coorong and Murray mouths in South Australia are all in much need of water.

All non-Indigenous people are encouraged to attend.

What makes Liz Hurley angry?

London, Mar 30 (ANI): Elizabeth Hurley has said that she has a short temper and can blow her top in traffic congestion, flight delays and even air fresheners.

While the model-cum-actress has taken it onto her to make peace between former boyfriend Hugh Grant and Matthew Freud, she does not hide the fact that she can also get angry easily.

“It only lasts a few minutes,” the Telegraph quoted her as saying.

She added that her principal irritants include: “Traffic congestion, flight delays, people talking with their mouths full, TV as background noise with no one watching, air fresheners …”

Hurley was less than impressed with Grant for his unseemly brawling with Freud, the PR executive, and now she attempts to broker peace accord between the warring factions.

“Hugh and I have known Matthew for years and we’re all friends. We’re having dinner together soon,” she said. (ANI)

Meredith’s water making us sick: residents

Residents of Meredith, north of Geelong complain their town water is so salty it is making some of them sick.

The local water authority says a new pipeline will make a big difference next year.

In the meantime locals just have to put up with the bad taste in their mouths.

After consulting a doctor, Carol Broadhurst is convinced she is allergic to Meredith’s drinking water.

She gets weepy eyes and skin irritations whenever she takes a shower.

“I had seven sties in five weeks, irritation all the time, weeping discharge out of both ears and the top of my eyelids are slimey, that’s the nicest word to use,” she said.

“It really is a bit of a joke that you can’t turn the tap on.”

She now relies on rainfall to fill her tank.

Other residents have told ABC News they suffer chronic stomach cramps.

One local egg farmer, Vincent Colla, carried out independent water testing which also revealed a high level of carbon.

He says that is affecting the health of his hens.

“You keep checking with other farms and you think there’s something not right here,” he said.

He complained to Barwon Water

“All they said was it’s not killing them. That tells me there’s something in there that shouldn’t be there.”

The water is sourced from the Moorabool river and services 370 households.

Reduced flows have almost pushed salinity levels above Australian drinking standards.

But Carl Bicknell of Barwon Water says the water is safe to drink.

“We have accelerated a project to put in a pipeline to give them a better supply,” he said.

“Barwon Water recognises the water isn’t up to the standard we’d like to supply.”

The water company says the town will be connected to Geelong’s supply by next year.

Lip-reading cellphone allows for soundless communication

Washington, Mar 5 (ANI): Karlsruhe Institute of Technology researchers have developed the phone of the future, a lip-reading cell that allows for soundless communication.

The software by German researchers enables people to move their mouths silently and to have the motion be picked up and translated into sound for people on the other end of the call, reports Fox News.

The process is based on the principle of electromyography – the acquisition and recording of electrical potentials generated by muscle activity.

The research will be presented at the Hanover CeBIT tradeshow. (ANI)

Stressed people likely to grind teeth at night

Washington, Mar 5 (ANI): Stress not only hurts your brain, but also has a bad effect on teeth, claims a new study.

Boffins writing in BioMed Central”s open access journal Head & Face Medicine studied the causes of ”sleep bruxism”, gnashing teeth during the night, finding that it was especially common in those who try to cope with stress by escaping from difficult situations.

Maria Giraki, from Heinrich-Heine-University, Düsseldorf, Germany, worked with a team of researchers to study the condition in 69 people, of whom 48 were ”bruxers”.

She said, “Bruxing can lead to abrasive tooth wear, looseness and sensitivity of teeth, and growth and pain in the muscles responsible for chewing. Its causes are still relatively unknown, but stress has been implicated. We aimed to investigate whether different stress-factors, and different coping strategies, were more or less associated with these bruxism symptoms”.

Tooth grinding was measured by thin plates that were placed in trial participants mouths” overnight, while stress and coping techniques were assessed by three questionnaires. Bruxing was not associated with age, sex or education level, but was more common in people who claimed to experience daily stress and trouble at work.

Giraki adds, “Our data support the assumption that people with the most problematic grinding do not seem to be able to deal with stress in an adequate way. They seem to prefer negative coping strategies like ”escape”. This, in general, increases the feeling of stress, instead of looking at the stressor in a positive way”. (ANI)

Chavs top the list of Brits’ 100 most annoying things

London, Sep 4 (ANI): A survey has revealed that chavs, who are typically portrayed as uncultured, anti-social, baseball cap wearing youths, have topped the list of the 100 most annoying things Brits find.

The survey revealed that more than 60 percent people found chavs to be “very annoying”.

The Brits were also annoyed by people driving too close behind them and people who smell, with 55 per cent and 52 per cent of the 3,000 people polled saying this was one of their biggest peeves.

Of the top 10 annoyances were people who eat with their mouth open (50 per cent), rude shop assistants (50 per cent), foreign call centres (49 per cent), stepping in dog dirt (49 per cent).

The list also included people who cough without covering their mouths (49 per cent), slow Internet connections (49 per cent) and poor customer service (47 per cent).

Lactofree’s Annual Intolerance Survey also found 79 percent of people were wound up easily by the little things in life, with 65 per cent driven to distraction.

On average, people find themselves getting annoyed more than three times a day and half of all respondents said they were likely to turn into a grumpy old man or woman.

The survey also found 39 per cent of Brits were cheesed off with the nation’s obsession with Z-list celebrities, while 38 per cent were fed up with the preoccupation with Katie Price and Peter Andre’s split saga.

Low on the list was the recession, with 31 per cent of people finding it annoying, and bankers, with 13 per cent finding them irritating.

Outside the top 100 were mice, mothers-in-law and karaoke, with 9 per cent of people finding these very annoying.

“‘This survey shows how intolerant we are as a nation, and how even the smallest of things annoy us – especially when, for many, their annoyances are driving them to distraction,” the Telegraph quoted Samantha Glassford, brand manager for Lactofree, as saying.

“‘This year the poll has shown how especially irritated we are by other people and their bad habits and how surprisingly low a nationwide burden such as the recession came in the annoyance list.

“For many of us, there really isn’t a cure for these everyday intolerances, yet when it comes to those food intolerances, there can be a solution.

“Lactofree, for example, will help those with lactose intolerance enjoy dairy again without any of the symptoms such as bloating, flatulence and feeling sluggish, so that’s one intolerance that can be dealt with,” she added. (ANI)

Scientists solve age-old mystery of horseshoe bat’s elongated nose

Washington, July 8 (ANI): Scientists have solved the mystery of a bat with an extraordinarily long nose, by determining that the creature uses its elongated nose to create a highly focused sonar beam, which helps in the detection of its environment.

The bat, called the Bourret’s horseshoe bat (known scientifically as the “Rhinolophus paradoxolophus,” meaning paradoxical crest), has a nose that is roughly 9 millimeters in length.

“The typical horseshoe bat’s nose is half that long,” said Rolf Mueller, an associate professor with the Virginia Tech mechanical engineering department and director for the Bio-inspired Technology (BIT) Laboratory in Danville, Virginia.

“This nose is so much larger than anything else,” among other bats of the region, he said.

Mueller’s findings show that the bat uses its elongated nose to create a highly focused sonar beam.

Bats detect their environment through ultrasonic beams, or sonar, emitted from their mouths – or noses, as in the case of the paradoxolophus bat.

The echoes of the sound wave convey a wealth of information on objects in the bat’s environment.

Much like a flashlight with an adjuster that can create an intense but small beam of light, the bat’s nose can create a small but intense sonar beam.

Mueller and his team used computer animation to compare varying sizes of bat noses, from small noses on other bats to the large nose of the paradoxolophus bat.

In what Mueller calls a perfect mark of evolution, he says his computer modeling shows the length of the paradoxolophus bat’s nose stops at the exact point the sonar beam’s focal point would become ineffective.

“By predicting the width of the ultrasonic beam for each of these nose lengths with a computational method, we found that the natural nose length has a special value: All shortened noses provided less focus of the ultrasonic beam, whereas artificially elongated noses provided only negligible additional benefits,” Mueller said.

“Hence, this unusual case of a biological shape can be predicted accurately from its physical function alone,” he added. (ANI)

Clean mouth can help preserve memory

Washington, June 20 (ANI): Keeping your teeth brushed and flossed can help preserve memory, say researchers.

The study at West Virginia University has found a link between gum disease and memory loss.

“Older people might want to know there’s more reason to keep their mouths clean – to brush and floss – than ever,” said Richard Crout, D.M.D., Ph.D., an expert on gum disease and associate dean for research in the WVU School of Dentistry.

“You’ll not only be more likely to keep your teeth, but you’ll also reduce your risk of heart attack, stroke and memory loss.

“This could have great implications for health of our aging populations,” Crout said.

“With rates of Alzheimer’s skyrocketing, imagine the benefits of knowing that keeping the mouth free of infection could cut down on cases of dementia,” he added.

The team conducted their research on 270 elderly aged 70 and older. They were given oral exams and memory test.

The findings revealed that 23 percent of the group suffers from mild to moderate memory loss.

“If you have a gum infection, you’ll have an increased level of inflammatory byproducts,” Crout explained.

“We’re looking for markers in the blood that show inflammation to see if there is a link to memory problems.

“We’d like to go full circle and do an intervention – to clean up some of the problems in the mouth and then see if the inflammatory markers go down,” he added. (ANI)

Shades around mouths and eyes let our brains recognise male and female faces

Washington, May 28 (ANI): Human brains possess an inherent ability to distinguish male faces from those of females based on facial cues and colouring, according to a Canadian study.

Universite de Montreal researchers and psychology Professor Frederic Gosselin has found that the luminescence of the eyebrow and mouth region plays a key role in rapid gender discrimination.

“As teenagers, dimorphism (systematic difference between sexes) increases in the nose, chin, mouth, jaw, eyes and general shape of faces. Yet we aren’t conscious of how our brain recognizes those differences,” said Nicolas Dupuis-Roy, lead author of the study.

For finding out the reference points, the researchers showed photos of 300 Caucasian faces to some 30 participants.

The subjects were asked to identify gender based on images in which parts of faces were concealed using a technology called Bubbles.

It was found that eyes and mouths, and particularly their subtle shading or luminance, are vital in identifying gender.

While previous studies found that the gap between the eyelid and eyebrow is essential in gender ID, the new study found that the shades of reds and greens around mouths and eyes led to faster gender discrimination.

“Studies have shown that an androgynous face is considered male if the skin complexion is redder, and considered female if the complexion is greener.

However, it is the opposite for the mouth. A woman’s mouth is usually redder. Our brain interprets this characteristic as female,” said Dupuis-Roy.

He added: “A man’s face usually reflects less light around the eyebrows. This is because they are usually thicker. The same applies to the upper lip and chin, which are hairier areas.”

He also noted that people clearly use colour to rapidly identify gender.

The study has been published in the Journal of Vision. (ANI)

Booze charge leaves bad taste in the mouths of IPL fans

Johannesburg, May 3 (ANI): Organizers of the Indian Premier League (IPL) have left a bad taste in the mouth of fans by imposing a pouring charge on the sale of alcohol at the Wanderers Ground here on Saturday.

For the sum of 40 000 dollars, a mere 0.001 percent of the IPL’s declared turnover of 2.4 billion dollars, the company who has the tender to sell alcohol at the Wanderers – Events Management – will be allowed to provide thirsty spectators with their tipple.

But what should be an utterly meaningless amount for the IPL is going to put the financial well being of a long-standing service provider to cricket in Johannesburg at risk – Rand 336 800, reports Sports24.

So while the IPL gorges itself on South African hospitality, it is making few friends amongst local cricket administrators or suppliers.

The Gauteng Cricket Board and the suite-holders at the Wanderers were earlier involved in a nasty tussle with the IPL, who had demanded all suites be handed over to them for their use.

Some senior Gauteng Cricket Board executives decided to stay away from the Wanderers in protest, after the IPL, with the tacit approval of Cricket South Africa, threatened to ban the sale of all alcohol at the stadium unless the pouring fee was paid.

It was also noticeable that only about a quarter of the suites at the ground had people in them, while there were many empty seats in the Unity Stand.

SA Breweries officials said the licensees at the Wanderers make a profit of Rand 6 a beer so, in order to just break even, they will need to sell 56 134 beers in the eight matches to be staged there. So that means over 7 000 drinks per game.

Perhaps the small change does matter more to the IPL in these times of recession than Modi and his crew are letting on. (ANI)

Even rinsing mouth with energy drinks can boost athletes’ performance

Washington, Apr 15 (ANI): Energy drinks are known to boost athletes’ performances. Now, a new study has shown that the drinks’ benefits are felt even if the drink is spat out rather than swallowed.

The research team led by Ed Chambers has shown that whether it’s real sugar or a tasteless carbohydrate, energy drinks can significantly boost performance in an endurance event, even if the drink isn’t ingested.

During the study, Chambers and his colleagues prepared drinks that contained either glucose (a sugar), maltodextrin (a tasteless carbohydrate) or neither.

The athletes were asked to complete a challenging time-trial during which they rinsed their mouths with one of the three concoctions.

The researchers found that athletes given the glucose or maltodextrin drinks outperformed those on ‘disguised’ water by 2-3 pct and sustained a higher average power output and pulse rate.

The authors revealed that there are certain receptors in the mouth independent from the usual ‘sweet’ taste buds must be responsible.

“Much of the benefit from carbohydrate in sports drinks is provided by signalling directly from mouth to brain rather than providing energy for the working muscles,” said Chambers.

With the help of neuro-imaging technique known as fMR, the researchers monitored the brain activity of the athletes and found that both glucose and maltodextrin triggered specific areas of the brain associated with reward or pleasure, while the artificial sweetener did not.

This acts to reduce the athletes’ perception of their workload, suggest the authors, and hence enables them to sustain a higher average output.

The study appears in The Journal of Physiology. (ANI)

Why autistic people fail to recognise faces

Washington, March 19 (ANI): An Indian-origin researcher at the Massachusetts Institute of Technology (MIT) has shed some light on why autistic people fail to recognise faces as effectively as their normal counterparts, by studying why they often fail to recognise faces in photographic negatives.

Pawan Sinha, an associate professor of Brain and Cognitive Sciences, says that a person’s eyes appear darker than the forehead and cheeks in nearly every normal lighting condition.

He believes that photo negatives are hard to recognize because they disrupt these very strong regularities around the eyes.

During a study, he and his colleagues asked subjects to identify photographs of famous people in not only positive and negative images, but also in a third type of image in which the celebrities’ eyes were restored to their original levels of luminance, while the rest of the photo remained in negative.

Sinha says that the subjects had a much easier time recognizing such “contrast chimera” images, because the light/dark relationships between the eyes and surrounding areas were the same as they would be in a normal image.

He adds that similar contrast relationships can be found in other parts of the face also, primarily the mouth, but those relationships are not as consistent.

“The relationships around the eyes seem to be particularly significant,” he says.

Sinha says that scientists studying face-perception skills in autistic children may find his observations interesting because such children are often reported to experience difficulties analysing facial information.

He points out that some studies have shown that those with autism tend to focus on the mouths rather than the eyes, which is why his study may help understand why such people have such difficulty recognizing faces.

The findings also suggest that neuronal responses in the brain may be based on these relationships between different parts of the face.

The team found that when they scanned the brains of people performing the recognition task, regions associated with facial processing were far more active when looking at the contrast chimeras than when looking at pure negatives. (ANI)

Greed for reward can spark unconscious learning in humans

Washington, Mar 12 (ANI): One need not have to pay attention to something in order to learn it, for now scientists have shown that the greed for reward can spark unconscious learning in humans.

The new study by researchers at Boston University demonstrated that stimulus-reward pairing could elicit visual learning in adults, even without awareness of the stimulus presentation or reward contingencies.

“Recent studies have raised the question of whether visual skill learning requires an active goal directed process or whether learning can occur automatically without any task, stimulus awareness, or goal directed behaviour,” said study author Dr. Aaron Seitz, from the Department of Psychology at the University of California, Riverside.

For the study, the researchers designed a novel experimental paradigm to take the “task” out of perceptual learning.

They asked the participants to view a computer monitor, maintain their gaze on a central spot and enjoy the occasional drop of water that was delivered to their mouths through a tube.

The drop of water was considered a reward because subjects were required to abstain from eating and drinking for five hours before the experimental session.

The visual stimuli that were paired with the liquid rewards were viewed with one eye, and were imperceptible to the subjects because contour rich patterns were continuously flashed to the other eye.

“The use of this procedure allowed us to examine the specific hypothesis that reward-related learning signals are sufficient to cause improvements in visual sensitivity for visual stimuli paired with rewards,” said Seitz.

It was found that stimulus-reward pairing was sufficient to cause learning, even when the subjects were not aware of the learned stimuli or stimulus-reward conditions.

The learning effects were specific to the eye receiving the stimuli, a condition indicative of an early, monocular stage of visual processing.

The results suggested that it was the automatic reinforcement mechanisms (such as those released at times of reward), rather than directed attention, that determined improvements in sensory skills.

“Our findings support the suggestion that visual skill learning is generally an unconscious process and that goal-directed factors, such as directed attention, serve mostly to bias how learning takes place rather than actually gating the learning process,” hypothesized Seitz.

The study has been published in the journal Neuron. (ANI)

Brit holidaymaker clicks genuine snap of a human spirit!

London, Mar 9 (ANI): A holidaymaker on the moors of North Yorkshire got a bolt form the blue when he returned home and saw that one of the pictures taken by him had a man-shaped apparition in it.

Even experts agree that the eerie photo is genuine, and has not been tampered with.

Unsuspecting Colin Foster, 34, of Wordsley, West Mids, aimed his new digital camera at the winter scenery during a trip earlier this year.

Although he didn’t see anything unusual while taking the snap, he realised the presence of a human spirit in one picture after he returned home from his backpacking tour and began checking the photos.

“My girlfriend and I were looking through them when she grabbed my hand and said, ‘Stop,’” the Sun quoted him as saying.

“She insisted I zoom in on one particular picture. At first I didn’t see it – but, as we zoomed in, we just turned to each other with our mouths agape.

“At the time I took the photo I did feel like I was being watched, but I just put that down to how remote and lonely the place was.

“All my friends and family are scratching their heads in awe,” he added.

And even experts were left astonished after examining the photo, one of hundreds taken by jobless Colin during his tour of northern England.

TV medium Craig Hamilton-Parker said: “I have checked it over for cheating, but it has none of the tell-tale signs of photo manipulating. The exact human shape leads me to say, ‘Yes, this is a real supernatural snap’. The Yorkshire Moors are renowned for their ghosts.”

Nick Thurston, of the UK British Paranormal Association, said: “This image is extremely clear and is certainly that of a spirit manifestation of a full human figure.” (ANI)

“Vampire” from Middle Ages discovered in Venice

London, March 7 (ANI): A skeleton found in a grave in Venice has been claimed by scientists as the first known example of people who were believed to be “vampires” in the Middle Ages.

According to a report in New Scientist, Matteo Borrini of the University of Florence in Italy found the skeleton.

He discovered the skeleton of a woman with a small brick in her mouth while excavating mass graves of plague victims from the Middle Ages on Lazzaretto Nuovo Island in Venice.

At the time the woman died, many people believed that the plague was spread by “vampires” which, rather than drinking people’s blood, spread disease by chewing on their shrouds after dying.

“Grave-diggers put bricks in the mouths of suspected vampires to stop them doing this,” Borrini said.

The belief in vampires probably arose because blood is sometimes expelled from the mouths of the dead, causing the shroud to sink inwards and tear.

Borrini, who presented his findings at a meeting of the American Academy of Forensic Sciences in Denver, Colorado, last week, claims this might be the first such vampire to have been forensically examined.

The skeleton was removed from a mass grave of victims of the Venetian plague of 1576.

Borrini said that his study details the earliest grave to show archaeological “exorcism evidence against vampires”. (ANI)
