Washington D.C. [USA], Feb. 22 : Now don't blame those chips and chocolates for you childs extra pounds, as a study says around 35-40 percent of a child's is inherited from their parents.
For the most obese children, the proportion rises to 55-60 percent, suggesting that more than half of their tendency towards obesity is determined by genetics and family environment.
The study, led by the University of Sussex, used data on the heights and weights of 100,000 children and their parents spanning six countries worldwide: the UK, USA, China, Indonesia, Spain and Mexico.
The researchers found that the intergenerational transmission of BMI (Body Mass Index) is approximately constant at around 0.2 per parent - i.e. that each child's BMI is, on average, 20 percent due to the mother and 20 percent due to the father.
The pattern of results, says lead author Professor Peter Dolton of the University of Sussex, is remarkably consistent across all countries, irrespective of their stage of economic development, degree of industrialisation, or type of economy.
Professor Dolton says, "Our evidence comes from trawling data from across the world with very diverse patterns of nutrition and obesity - from one of the most obese populations - USA - to two of the least obese countries in the world - China and Indonesia."
Adding, "This gives an important and rare insight into how obesity is transmitted across generations in both developed and developing countries. We found that the process of intergenerational transmission is the same across all the different countries."
The findings are published in the journal Economics and Human Biology.
The study also shows how the effect of parents' BMI on their children's BMI depends on what the BMI of the child is. Consistently, across all populations studied, they found the 'parental effect' to be lowest for the thinnest children and highest for the most obese children. For the thinnest child their BMI is 10 per cent due to their mother and 10 per cent due to their father. For the fattest child this transmission is closer to 30 per cent due to each parent.
"This shows that the children of obese parents are much more likely to be obese themselves when they grow up - the parental effect is more than double for the most obese children what it is for the thinnest children," say Professor Dolton.
"These findings have far-reaching consequences for the health of the world's children. They should make us rethink the extent to which obesity is the result of family factors, and our genetic inheritance, rather than decisions made by us as individuals," he explained.

Washington D.C. [USA], Feb. 21 : Only exercise is not enough to maintain that figure, which is an after effect of much toil and sweat!
A study by American College of Physicians say that a weight loss program that incorporates a maintenance intervention could help participants be more successful at keeping off pounds long term.
Researchers found that primarily telephone-based intervention, focused on providing strategies for maintaining weight loss modestly, slowed the rate of participants' weight regain after weight loss.
Results of a randomised trial are published in Annals of Internal Medicine.
Despite the efficacy of behavioral weight loss programs, weight loss maintenance remains the holy grail of weight loss research. After initial weight loss, most people tend to regain weight at a rate of about two to four pounds a year.
Teaching people weight maintenance skills has been shown to slow weight gain, but can be time and resource-intensive. Simple and effective weight maintenance interventions are needed.
Researchers tested a weight maintenance intervention on obese outpatients who had lost an average of 16 pounds during a 16-week, group-based weight loss program to determine if a low-intensity intervention could help participants keep off the weight they lost. Participants were randomly assigned to the intervention or usual care. The intervention focused on providing participants with skills to help them make the transition from initiating weight loss to maintaining their weight.
Over the first 42 weeks, the intervention shifted from group visits to individual telephone calls, with decreased frequency of contact. There was no intervention contact during the final 14 weeks. The usual care group had no contact except for weight assessments. After 56 weeks, mean weight regain in the intervention group was about 1.5 pounds compared to 5 pounds in the usual care group. The evidence suggests that incorporating a weight maintenance intervention into clinical or commercial weight loss programs could make them more effective over the long term.

New Delhi [India], Feb 20. : In order to persuade someone to quit smoking, it is the 'emotions' that need to be triggered rather than inciting fear in an individual.
A new study by Michigan State University researchers has found out the following which was published in Communication Research Reports.
Advertisers often use nostalgia-evoking messages to promote consumer products, and that tactic could be just as effective in encouraging healthy behaviors, argue Ali Hussain, a doctoral candidate in the School of Journalism, and Maria Lapinski, professor in the Department of Communication.
"A lot of no-smoking messages are centered around fear, disgust and guilt," Hussain said. "But smokers often don't buy the messages and instead feel badly about themselves and the person who is trying to scare them."
According to the Centers for Disease Control and Prevention, cigarette smoking is the leading cause of preventable disease in the United States, accounting for one of every five deaths. Smoking rates have declined, but in 2015, 15 of every 100 adults were active smokers.
Despite the health risks, a key hurdle for health communicators is rejection and avoidance of messages, Lapinski said.
Hoping to find a solution, researchers conducted a study of smokers, ages 18 to 39, exposing some to a nostalgic public service announcement Hussain created and some to a control message.
Those who viewed the PSA reported greater nostalgic emotions and displayed stronger negative attitudes toward smoking, especially women.
Starting with images of childhood memories, the PSA script includes phrases such as, "I remember when I was a boy" and "I miss the simplicity of life, being outside on a warm summer night," making references to familiar smells and tastes from bygone days. It ends with the narrator remembering when someone introduced him to cigarettes and a call to action. Nostalgia-themed PSAs play off consumers' most cherished and personal memories, so they feel more engaged, the researchers said. And that nostalgic thinking influences attitudes and behaviors.
"Our study, which to our knowledge is first of its kind, shows promise for using nostalgic messages to promote pro-social behaviors," Lapinski said. "We know that policy and environmental changes have an influence on smoking and this study indicates persuasive messages can influence smoking attitudes." (ANI)Region: IndiaGeneral: Health
New Delhi [India], Feb 19. : Lefty or righty? Well it was decided when you were still in your mum's womb!
A preference for the left or the right hand might be traced back to asymmetry. These results fundamentally change our understanding of the cause of hemispheric asymmetries.
The study was published in the journal eLife.
To date, it had been assumed that differences in gene activity of the right and left hemisphere might be responsible for a person's handedness. A preference for moving the left or right hand develops in the womb from the eighth week of pregnancy, according to ultrasound scans carried out in the 1980s. From the 13th week of pregnancy, unborn children prefer to suck either their right or their left thumb.
Arm and hand movements are initiated via the motor cortex in the brain. It sends a corresponding signal to the spinal cord, which in turn translates the command into a motion. The motor cortex, however, is not connected to the spinal cord from the beginning. Even before the connection forms, precursors of handedness become apparent. This is why the researchers have assumed that the cause of right respective left preference must be rooted in the spinal cord rather than in the brain.
The researchers analysed the gene expression in the spinal cord during the eighth to twelfth week of pregnancy and detected marked right-left differences in the eighth week -- in precisely those spinal cord segments that control the movements of arms and legs. Another study had shown that unborn children carry out asymmetric hand movements just as early as that.
The researchers, moreover, traced the cause of asymmetric gene activity. Epigenetic factors appear to be at the root of it, reflecting environmental influences. Those influences might, for example, lead to enzymes bonding methyl groups to the DNA, which in turn would affect and minimise the reading of genes. As this occurs to a different extent in the left and the right spinal cord, there is a difference to the activity of genes on both sides. (ANI)Region: New DelhiIndiaGeneral: Health
New Delhi [India], Feb 19. : Do you find it difficult hearing out people at a noisy bar or a restaurant even though you have passed the hearing test with flying colors? Well, you might be secretly deaf!
Now, less than six years since its initial description, scientists have made great strides in understanding what hidden hearing loss is and what causes it. In research published in Nature Communications, University of Michigan researchers report a new unexpected cause for this auditory neuropathy, a step toward the eventual work to identify treatments.
"If people can have hidden hearing loss for different reasons, having the ability to make the right diagnosis of the pathogenesis will be critical," says author Gabriel Corfas, Ph.D., director of the Kresge Hearing Research Institute at Michigan Medicine's Department of Otolaryngology - Head and Neck Surgery.
Corfas published the research with co-author Guoqiang Wan, now with Nanjing University in China. They discovered using mice that disruption in the Schwann cells that make myelin, which insulates the neuronal axons in the ear, leads to hidden hearing loss. This means hidden hearing loss could be behind auditory deficits seen in acute demyelinating disorders such as Guillain-Barre syndrome, which can be caused by Zika virus.
Corfas and Wan used genetic tools to induce loss of myelin in the auditory nerve of mice, modeling Guillain-Barre. Although the myelin regenerated in a few weeks, the mice developed a permanent hidden hearing loss. Even after the myelin regenerated, damage to a nerve structure called the heminode remained.
Synapse loss versus myelin disruption
When the ear is exposed to loud noises over time, synapses connecting hair cells with the neurons in the inner ear are lost. This loss of synapses has previously been shown as a mechanism leading to hidden hearing loss.
In an audiologist's quiet testing room, only a few synapses are needed to pick up sounds. But in a noisy environment, the ear must activate specific synapses. If they aren't all there, it's difficult for people to make sense of the noise or words around them. That is hidden hearing loss, Corfas says.
"Exposure to noise is increasing in our society, and children are exposing themselves to high levels of noise very early in life," Corfas says. "It's clear that being exposed to high levels of sound might contribute to increases in hidden hearing loss."
The newly identified cause -- deficiency in Schwann cells -- could occur in individuals who have already had noise exposure-driven hidden hearing loss as well. "Both forms of hidden hearing loss, noise exposure and loss of myelin, can occur in the same individual for an additive effect," Corfas says.
Previously, Corfas' group succeeded in regenerating synapses in mice with hidden hearing loss, providing a path to explore for potential treatment.
While continuing this work, Corfas started to investigate other cells in the ear, which led to uncovering the new mechanism.
There are no current treatments for hidden hearing loss. But as understanding of the condition improves, the goal is for the research to lead to the development of drugs to treat it.
"Our findings should influence the way hidden hearing loss is diagnosed and drive the future of clinical trials searching for a treatment," Corfas says. "The first step is to know whether a person's hidden hearing loss is due to synapse loss or myelin/heminode damage."(ANI)Region: IndiaGeneral: Health
Washington D.C. [USA], Feb. 18 : Clean drinking water for everyone is one major health goal for decades, in one a shocking revelation, a study warns that while it reduces chances of catching many deadly diseases, but it can increase the risk of childhood asthma.
Researchers from the University of British Columbia in Canada suggested that there could be a link between the risk of asthma and the cleanliness of the environment.
The findings indicated that while gut bacteria plays a role in preventing asthma, but it was the presence of a microscopic fungus or yeast known as Pichia that was more strongly linked to asthma. Instead of helping to prevent asthma, however, the presence of Pichia in those early days puts children at risk.
"Children with this type of yeast called Pichia were much more at risk of asthma," said Brett Finlay.
"That was a surprise because we tend to think that clean is good, but we realise that we actually need some dirt in the world to help protect you," Finlay added.
The new research furthers our understanding of the role microscopic organisms play in our overall health.
In previous research, Finlay and his colleagues identified four gut bacteria in children and if present in the first 100 days of life, seem to prevent asthma.
In a follow-up to this study, they repeated the experiment using fecal samples and health information from 100 children in a rural village in Ecuador.
As part of the study, the researchers noted whether children had access to clean water.
They found a yeast in the gut of new babies in Ecuador that appears to be a strong predictor that they will develop asthma in childhood.
They also found the presence of four types of bacteria in the gut of babies less than 100 days old seemed to prevent them from developing asthma in later life.
"Those that had access to good, clean water had much higher asthma rates and we think it is because they were deprived of the beneficial microbes," Finlay stated. (ANI)Region: WashingtonGeneral: Health
Washington D.C. [USA], Feb. 18 : Now you can save your kid from surgery, as a study shows that antibiotics may be an effective treatment for acute non-complicated appendicitis in children, instead of surgery.
Appendicitis is a serious medical condition in which the appendix becomes inflamed and causes severe pain.
The appeared in the journal of Pediatrics
The condition, which causes the appendix -- a small organ attached to the large intestine -- to become inflamed due to a blockage or infection, affects mainly children and teenagers.
Appendicitis is currently treated through an operation to remove the appendix, known as an appendicectomy, and it is the most common cause of emergency surgery in children.
The study, led by Nigel Hall from the University of Southampton in England, assessed existing literature published over the past 10 years that included 10 studies reporting on 413 children, who received non-operative treatment rather than an appendectomy.
It showed that no study reported any safety concern or specific adverse events related to non-surgical treatment, although the rate of recurrent appendicitis was 14 percent.
"Our review shows that antibiotics could be an alternative treatment method for children. When we compared the adult literature to the data in our review it suggested that antibiotic treatment of acute appendicitis is at least as effective in children as in adults,"
To further this research, the scientists are currently carrying out a year-long feasibility trial which will see children with appendicitis randomly allocated to have either surgery or antibiotic treatment.
"In our initial trial, we will see how many patients and families are willing to join the study and will look at how well children in the study recover. This will give us an indication of how many children we may be able to recruit into a future larger trial and how the outcomes of non-operative treatment compare with an operation," Hall stated.

Washington D.C. [USA], Feb. 18 : Attention new mommies, sing lullabies to your new born to feel more connected to your babies, suggests a study.
The research, published in the Journal of Music Therapy, finds that through song, the infants are provided with much-needed sensory stimulation that can focus their attention and modulate their arousal.
"One of the main goals of the research was to clarify the meaning of infant-directed singing as a human behaviour and as a means to elicit unique behavioural responses from infants," said study author Shannon de l'Etoile from the University of Miami in the US.
The researchers also explored the role of infant-directed singing in relation to intricate bond between mother and infant.
They filmed 70 infants and observed their responses to six different interactions: mother sings an assigned song, "stranger" sings an assigned song, mother sings song of choice, mother reads book, mother plays with toy and the mother and infant listen to recorded music.
The findings suggested that high cognitive scores during infant-directed singing suggested that engagement through song is just as effective as book reading or toy play in maintaining infant attention and far more effective than listening to recorded music.
The results also revealed that when infants were engaged during song, their mother's instincts are also on high alert and when infant engagement declined the mother adjusted her pitch, tempo or key to stimulate and regulate infant response.
For mothers with postpartum depression, infant-directed singing creates a unique and mutually beneficial situation," de l'Etoile noted.
"Simultaneously, mothers experience a much-needed distraction from the negative emotions and thoughts associated with depression, while also feeling empowered as a parent," de l'Etoile explained. (ANI)Region: WashingtonGeneral: Health
Washington D.C. [USA], Feb. 17 : As a saying, "beauty is skin deep" sounds fair, but in the real world where money is top priority, physical attractiveness might have a lot more prominence than just inner beauty.
A study finds that healthier, more intelligent people have superior personality traits are preferred more for taking fatter pay checks home than those who are aesthetically compromised.
The study appeared in Springer's Journal of Business and Psychology.
The findings indicated that population-based surveys showed that people who are physically attractive earn more than the average Joe or Jane, while those who are aesthetically compromised - that gives pleasure through beauty - earn less.
More attractive lawyers and MBA graduates are also said to earn more.
Researchers, Satoshi Kanazawa of the London School of Economics and Mary Still of the University of Massachusetts in Boston analysed a nationally representative sample from a US data set that had very precise and repeated measures of physical attractiveness.
It measured physical attractiveness of all respondents on a five-point scale at four different points in life over 13 years.
Their analysis showed that people are not necessarily discriminated against because of their looks. The beauty premium theory was dispelled when the researchers took into account factors such as health, intelligence and major personality factors together with other correlates of physical attractiveness.
Healthier and more intelligent respondents and those with more conscientious, more extraverted and less Neurotic personality traits earned significantly more than others.
"Physically more attractive workers may earn more, not necessarily because they are more beautiful, but because they are healthier, more intelligent and have better personality traits conducive to higher earnings, such as being more conscientious, more extraverted and less Neurotic," Kanazawa explained.
Still stated that the methods used in other studies might explain why the findings in the current research are contrary to many current thoughts about the economics of beauty. (ANI)Region: WashingtonGeneral: Health
London [UK], Feb. 17 : Consume a healthy dose of vitamin D supplements during winters, as a study finds that taking them may protect you from acute respiratory infections and flu.
The study, published in The BMJ, suggests that taking vitamin D - also known as the sunshine vitamin - may have benefits beyond bone and muscle health and protects against acute respiratory infections.
Researchers from Queen Mary University of London found that vitamin D supplementation cut the proportion of participants experiencing at least one acute respiratory tract infection by 12 percent, reports the Mirror.
"The bottom line is that the protective effects of vitamin D supplementation are strongest in those who have the lowest vitamin D levels and when supplementation is given daily or weekly rather than in more widely spaced doses," said lead researcher Adrian Martineau.
Respiratory tract infections are infection of the sinuses, throat, airways or lungs and can last up to 30 days.
They analyzed the data from almost 11,000 participants aged up to 95, who took part in 25 clinical trials.
The findings indicated that that supplements can help to prevent acute respiratory tract infections, particularly among those who are deficient in vitamin D.
After adjusting for other potentially influential factors, the team found that vitamin D supplementation cut the proportion of the participants experiencing at least one acute respiratory tract infection by 1 percent.
The results fit with the observation that colds and flu are most common during winter and spring, when levels of vitamin D are at their lowest.
"The evidence on vitamin D and infection is inconsistent and this study does not provide sufficient evidence to support recommending vitamin D for reducing the risk of respiratory tract infections," Martineau explained. (ANI)Region: LondonGeneral: Health
Washington D.C. [USA], Feb. 15, : A study finds that changes in the size of mitochondria in a small subset of brain cells, may play a crucial role in safely maintaining blood sugar levels.
The study appeared in the journal Cell Metabolism.
"Low blood sugar can be as dangerous as high blood sugar," said senior author Sabrina Diano.
"We've found that changes in the size of mitochondria -- small intracellular organelles responsible for energy production -- in certain cells in the brain, could be key to maintaining the blood sugar within a safe range," Diano added.
"This new finding adds to our understanding of how the body keeps blood sugar levels within a safe range when sugar levels drop, like during fasting, or when they spike after a meal," Diano added.
The team designed the study to help understand how neurons in the brain that regulate appetite affect systemic glucose levels.
They used mouse models in which a specific mitochondrial protein, dynamin-related protein 1 (DRP1), was either missing or present in varying amounts in the subset of brain cells that sense circulating sugar levels.
They found that depending on whether the mouse was hungry or not, mitochondria displayed dynamic changes in size and shape, driven by the DRP1 protein.
"We found that when DRP1 activity in the neurons was missing, these neurons were more sensitive to changes in glucose levels," said Diano,
"What surprised our research team was that these intracellular changes in this small subset of neurons were specifically important to increase blood sugar levels during a fasting period by activating the so-called counter-regulatory responses to hypoglycemia, in which the brain senses lower glucose levels and sends signals to peripheral organs such as the liver to increase glucose production," diano explained.

Washington D.C. [USA], Feb. 15 : A team of U.S. researchers finds that a combination of drugs may help in killing of brain cancer tumour cells with high cure rates in mice.
A combination of drugs may help in killing of brain cancer tumour cells with high cure rates in mice, finds a study.
The study appeared in journal Nature Communications.
Researchers at the Children's Hospital of Eastern Ontario in Ottawa conducted the study on mice and found that a combination of drugs known as SMAC Mimetics and immune checkpoint inhibitors (ICIs) amplifies kill rates of cancer tumour cells in laboratory testing.
They also found that the new mechanism also promotes long-term immunity against glioblastoma tumours and is highly effective against breast cancer and multiple myeloma - a malignant tumour of the bone marrow.
"These findings represent a significant evolution in our research and the field of immunotherapy. We are the first in the world to show the synergistic tumour-killing impact of combining SMAC Mimetics with immune checkpoint inhibitors for glioblastoma," said Robert Korneluk from the University of Ottawa.
"You could say it takes two to tango. We believe that it takes a combination strategy to impact cancer cure rates," Korneluk added.
The finds indicate that SMAC Mimetics also have a powerful synergistic effect with ICIs, relatively new drugs that are showing great promise in the clinic.
"Two drug companies have initiated human clinical trials this year to assess the impact of this combination of SMAC Mimetics and ICIs on patients with a variety of cancers," said another researcher ,Eric Lacasse.
"Although it could be years before any clinical trials begin for adults or children with the deadly brain cancer, glioblastoma, we're looking forward to seeing how scientific evidence from these experimental treatments adds to our knowledge," Lacasse explained.

New Delhi [India], Feb. 15 : In what is a new approach to joint fractures in India, doctors at Indian Spinal Injuries Hospital, New Delhi, have used an arthroscope even while fixing a simple ankle fracture.
This the first time such a surgery is being done in Delhi. When a patient comes in with a joint fracture, a tiny camera is used to go inside the joint, to help doctors understand internal damage.
"Usually, we simply align the bone so it sets; we don't really look at cartilage damage. Naturally, on impact, the cartilage may also be broken-a complication of the fracture. So we open up the joint, sending in an arthroscope, to understand any other damage. Previously, we would fix the bone, and the patient would often get recurring pain. After several months, doctors would realize that there has been damage to the cartilage as well. By then, it is difficult to treat and the pain becomes a lifelong problem," said Dr Maninder Singh, Senior Consultant Orthopaedic Surgeon, Chief-Foot & Ankle Unit, Coordinator Sports Injury Unit, Indian Spinal Injuries Centre, New Delhi.
Adding, "To avoid this, the arthroscopic-assisted ankle fracture fixation method, gives the best possible patient outcome when it comes to ankle-fracture surgeries."
Understanding the importance of the surgery and the effect it is bound to have on patient outcomes, Indian Spinal Injuries Hospital has subsidized the rate of the arthroscopy, to encourage more and more people adopt this when they come in with ankle fractures. Within the Foot and Ankle Unit, it has become the protocol to do the arthroscopy. The hospital is now carrying out a study on the level of success of the surgery, again one of the first in the country.
"Once we know the extent of the damage to the cartilage, we can take suitable action, such as the shaving off any tiny shards of cartilage, so that it does not float around the joint and cause immense pain. Sometimes, the extent of breakage is so great that it needs a microfracture. This is a surgical technique wherein holes are drilled into the underlying bone in order to stimulate cartilage regrowth. The body's own stem cells will grow into new cartilage" said Dr Singh.
The arthroscopic-assisted ankle fracture fixation ensures that the surgeon is better able to understand how an accident or even a twist in the ankle that causes a fracture have impacted the joint in its entirety. It helps the doctor prescribe the best possible treatment for the patient's unique case, thereby getting the best patient outcomes.
While the surgery at Indian Spinal Injuries Hospital was done on the ankle, this can be performed on other joints as well.(ANI)Region: IndiaGeneral: Health
New Delhi [India] Feb 14. : Finally the answer to the question 'How to live a long life?' has been found. At least, that's what it seems from a recent research.
There's a multi-billion-dollar industry devoted to products that fight signs of aging, but moisturizers only go skin deep. Aging occurs deeper, at a cellular level, and scientists have found that eating less can slow this cellular process.
Recent research published in Molecular and Cellular Proteomics offers one glimpse into how cutting calories impacts aging inside a cell. The researchers found that when ribosomes, the cell's protein makers, slow down, the aging process slows too. The decreased speed lowers production but gives ribosomes extra time to repair themselves.
"The ribosome is a very complex machine, sort of like your car, and it periodically needs maintenance to replace the parts that wear out the fastest," said Brigham Young University biochemistry professor and senior author John Price. "When tires wear out, you don't throw the whole car away and buy new ones. It's cheaper to replace the tires."
So what causes ribosome production to slow down in the first place? At least for mice: reduced calorie consumption.
Price and his fellow researchers observed two groups of mice. One group had unlimited access to food while the other was restricted to consume 35 percent fewer calories, though still receiving all the necessary nutrients for survival.
"When you restrict calorie consumption, there's almost a linear increase in lifespan," Price said. "We inferred that the restriction caused real biochemical changes that slowed down the rate of aging."
Price's team isn't the first to make the connection between cut calories and lifespan, but they were the first to show that general protein synthesis slows down and to recognize the ribosome's role in facilitating those youth-extending biochemical changes.
"The calorie-restricted mice are more energetic and suffered fewer diseases," Price said. "And it's not just that they're living longer, but because they're better at maintaining their bodies, they're younger for longer as well."
Ribosomes, like cars, are expensive and important, they use 10-20 percent of the cell's total energy to build all the proteins necessary for the cell to operate. Because of this, it's impractical to destroy an entire ribosome when it starts to malfunction. But repairing individual parts of the ribosome on a regular basis enables ribosomes to continue producing high-quality proteins for longer than they would otherwise. This top-quality production in turn keeps cells and the entire body functioning well.
Despite this study's observed connection between consuming fewer calories and improved lifespan, Price assured that people shouldn't start counting calories and expect to stay forever young. Calorie restriction has not been tested in humans as an anti-aging strategy, and the essential message is understanding the importance of taking care of our bodies.
"Food isn't just material to be burned -- it's a signal that tells our body and cells how to respond," Price said. "We're getting down to the mechanisms of aging, which may help us make more educated decisions about what we eat."(ANI)Region: IndiaGeneral: Health
Edinburgh [UK], Feb. 13 : If you are an elder sibling, you may already assume that first-born children are smarter than younger siblings. But new research out of the University of Edinburgh asks what many families have long pondered - and it turns out that the answer is more complicated than you might think.
The research by the University of Edinburgh has found that first-born children have superior thinking skills in comparison to their younger siblings.
Economists at the University of Edinburgh, Analysis Group and the University of Sydney examined survey data collected by the US Bureau of Labor Statistics.
And the researchers found that first-borns scored higher than siblings in IQ tests as early as age one.
The study, published in the Journal of Human Resources, observed nearly 5,000 children from pre-birth to age 14, with children assessed every two years.
What's more, the research found that all children got the same degree of emotional support.
Lead on the research, Dr Ana Nuevo-Chiquero, said the results could explain differences in achievement observed in education and employment down the line.
Dr Nuevo-Chiquero, of Edinburgh University's school of economics, said "Our results suggest that broad shifts in parental behaviour are a plausible explanation for the observed birth order differences in education and labour market outcomes."
Typically, so say past studies, first-born kids are usually more successful and ambitious.
One conducted by the University of Essex found that the eldest child is 16 percent more likely to pursue higher education.
But they're also more likely to be short-sighted, so it's swings and roundabouts, right? (ANI)Region: United KingdomGeneral: Health
New Delhi [India], Feb.12 : A happy person makes for happy, long, luscious, shiny and lustrous hair. So says famous hair specialist Jawed Habib.
He also maintains that the meditative practice of yoga can also contribute to pretty, thick and feminine hair.
"All one needs to do is practice hair yoga by following a healthy and balanced diet, having your meals on time, drinking milk, consuming lots of water and spending some time with oneself. Most importantly, smile for healthy, lustrous hair," says Habib.
"We all think good shampoos, conditioners and expensive salon treatments can make our hair healthy and beautiful, but we actually are completely unaware of reality. Good products and treatments are definitely important for hair. Hair care is beyond products and treatments. Understanding hair and its needs make things less complicated. Water is important for hair health. But not just drinking some 1-2 liters a day is all you need. Water for hair means drinking it well and rinsing it well," he adds.
Habib says drinking plenty of water helps to hydrate your hair and what is applied to the hair must also be well rinsed with cool water.
"Either don't apply any hair care product or make sure you have enough water to wash it off. If you understand the water rule for hair, half of your hair problems are solved. It's simple - drink it well, rinse with it well," he said.
"Young people think conditioner daily or an occasional spa treatments is enough.. No! Hair needs natural conditioning daily. Preconditioning is the answer-apply oil for five minutes daily before a wash. Use basic oils and not blends. Wash hair with normal hair shampoo, no other shampoo is required. Cut hair regularly, which means about 8-10 weeks. No chemical experiments at home and healthy lifestyle," he adds.
On the issue of trends in hair care, Habib said, "Always remember trends are temporary, but your hair is permanent. So, be wise. Work on balanced cuts. A hair cut is the foundation of a good look. Don't keep the length too long, long hair is not easy to look stylish. Get colour, Honey Blonde, Hazelnut and Khaki blondes are good options to get instant spark to the hair. Always go to professionals for hair styling, they know your hair more than you."
He further states that the scalp needs to be cleaned just the way your face is, and adds that a clean scalp prevents both dandruff and greying. In case you need to use an anti-dandruff shampoo, use it just once a week.
"I believe hair grooming is a science. A hair dresser is both your doctor and your designer. He will know exactly what to do with your hair, according to your personality, skin tone and hair texture."
He also said that oil does nothing but bring down the density of hair to manageable proportions. This , he said, can also be done by hair re-bonding and use of serums.
Short, shoulder-length hair can make any woman look beautiful. The shorter her hair is, the younger she looks. A hair-dresser can read and feel hair and a hair cut that originates from his or her mind and not eyes, makes the perfect cut, said Habib. (ANI)Region: IndiaGeneral: Health
Washington D.C. [USA], Feb. 12 : This happens to us all. Office frustrations are mostly never confined to just the work-place. To prevent them from spilling over into the house, scientists suggest taking a brisk walk or a long swim.
A study published in the Journal of Applied Psychology tracked participants' sleep patterns and daytime physical movements found employees who recorded an average of more than 10,900 steps each day were less likely to perpetuate abuse at home than those recording fewer than 7,000.
"Research shows employees who are mistreated at work are likely to engage in similar behaviors at home," said University of Central Florida's College of Business management professor Shannon Taylor, who teamed up with researchers from Illinois and Wisconsin for the study. "If they've been belittled or insulted by a supervisor, they tend to vent their frustration on members of their household. Our study shows that happens because they're too tired to regulate their behavior."
The study concludes sleep and exercise are intervention points that can be leveraged to prevent the spread of harmful behavior. Study participants included 118 MBA students with full-time jobs who took a survey and then wore activity monitors for a week. A follow-up survey was then sent to the participants' cohabitants.
Taylor said the study found that burning an additional 587 calories can reduce the harmful effects of mistreatment and help prevent it from carrying into the home. For the average American man, these gains can be achieved with an hour of swimming or a brisk 90-minute walk.
"The findings are particularly compelling given recommendations from the Centers for Disease Control and the American Heart Association to walk between 8,000 and 10,000 steps per day," Taylor said. "I also think the study gives us a new perspective on the importance of getting an adequate amount of sleep and exercise. It's not just good for you, it's good for your spouse, too."
Taylor is an associate professor and Ph.D. program coordinator in the management department at the University of Central Florida in Orlando.

Washington D.C. [USA], Feb. 11 : A study reveals would-be mothers, carrying female fetuses may exhibit a heightened inflammatory response that can contribute to sickness-related symptoms, such as achiness and fatigue.
According to researchers, women, over the years, have claimed that body of a mother, carrying male and female baby, react differently.
The study, published in journal Brain, Behavior and Immunity, shows the sex of a baby is associated with pregnant women's immune responses.
Inflammation is a critical part of the immune response involved in wound healing and responses to viruses, bacteria and chronic illnesses and excessive inflammation is stressful to the body and can contribute to sickness-related symptoms, such as achiness and fatigue.
Researchers from the Ohio State University's wexner medical center in the US followed 80 pregnant women across the course of their pregnancy and examined whether women exhibited different levels of immune markers called cytokines based on fetal sex.
The analyses were conducted on levels of cytokines in the blood and levels produced by a sample of immune cells that were exposed to bacteria in the lab.
"While women didn't exhibit differences in blood cytokine levels based on fetal sex, we did find that the immune cells of women carrying female fetuses produced more pro-inflammatory cytokines when exposed to bacteria," said principal investigator of the study Amanda Mitchell.
"This means that women carrying female fetuses exhibited a heightened inflammatory response when their immune system was challenged, compared to women carrying male fetuses," Mitchell explained.
Adding, "This research helps women and their obstetricians recognise that fetal sex is one factor that may impact how a woman's body responds to everyday immune challenges and can lead to further research into how differences in immune function may affect how a women responds to different viruses, infections or chronic health conditions (such as asthma)."
While maternal inflammation can affect outcomes related to the fetus, like timing of birth, but more research is necessary to understand how fetal sex is associated with maternal inflammation. It's possible the sex hormones or other hormones in the placenta affect maternal inflammation levels, Mitchell said. (ANI)Region: WashingtonGeneral: Health
London [UK], Feb. 10 : If you are doing a hot yoga - a style of yoga that takes place in a room heated between 26Â°C - 40.5Â°C - make sure you are drinking plenty of water before, during and after the class as it makes people more susceptible to dehydration and muscle injuries.
According to researchers from Washington University in St. Louis of United States, people doing hot yoga should take a break, cool down and get themselves hydrated as proper hydration is the key, reports The Mirror.
The findings indicated that more than half of the people doing hot yoga experience dizziness, lightheadedness, nausea or dehydration, despite benefits such as greater flexibility and improvements in mood, fitness and stamina and if people are feeling dizzy - have headaches or feel weak or fatigued - then it may be related to fluid loss.
"People may assume the warnings, benefits and possible risks are the same for all types of yoga and that's simply not true," said assistant professor Casey Mace.
"There may be a misconception that these feelings are normal, but they're not," she says.
Doctors in Chicago reported last summer on a case, involving a healthy 35-year-old woman, who went into cardiac arrest induced by heatstroke during a hot yoga class. The woman survived.
Muscle and joint injuries may be common with hot yoga because the heat makes people feel more supple than they actually are.
"You have to be a bit cautious when you look at studies, because they are conducted with high-quality, well-trained yoga teachers under the best of circumstances," said another researcher Carol Ewing Garber.
"The reality is that out in the real world, there's a lot of variability across instructors in terms of their training," Garber added.
If you have low blood pressure or any health condition, consult your doctor before trying hot yoga and if you are prone to heatstroke or dehydration, then you should stick with regular yoga, the authors concluded. (ANI)Region: LondonGeneral: Health
New Delhi [India], Feb. 9 : Winter problems are no longer restricted to cough, cold and flu. When the temperature drops and the cold winds begin to blow, the air becomes drier and our bodies get less moisture than they do in warmer months, leading to dehydration. And that is the first step towards a Urinary Tract Infection (UTI).
UTI refers to a bacterial infection anywhere in the urinary tract, such as the bladder, kidneys, ureters, or the urethra and one tends to be exposed to such infections in winters.
Dr. Anant Kumar, Chairman - Urology, Renal Transplant, Robotics, and Uro-Oncology Max Super Speciality Hospital, Saket said, " Our bodies suffer from UTI in winters as we stop drinking water. While we can invest in any warm beverage rather than icy water when it comes to wintertime, it's still critical to maintain the water intake. Consumption of less water, especially during winter is one of the main causes that worsen UTI."
Moreover, the main symptom of the infection which is burning sensation is usually considered a result of eating high calorie rich food during this season. This delays the patients from approaching the doctors on time. Also, women who make contact with the infections are so apprehensive of reporting it to the doctors that they prefer to self-medicate, which in turn makes the infection acute.
While most cases of bladder infection occur suddenly, others may recur over the long-term. Early treatment is keys to preventing the spread of the infection. Bacteria that enter through the urethra and travel into the bladder cause bladder infections. Normally, the body removes the bacteria by flushing them out during urination. This overwhelms the body's ability to destroy them, resulting in a bladder infection.
According to Dr. Kumar, for preventing bladder infections the following lifestyle changes may help reduce or eliminate the occurrence of bladder infections:
â€¢ Change underwear daily: Since women are more prone to infections, they should change their undergarments twice a day.
â€¢ Don't hold urine: Urinate as soon as you feel the need. Holding urine for long multiplies the bacteria, thus causes infection.
â€¢ Wear cotton underwear: Cotton underwear's are comfortable, especially for women as it helps keep the vagina dry. Synthetic underwear's cause excessive friction, thus leading to discharge of fluid which causes irritability.
â€¢ Don't Use feminine hygiene sprays: The pH in the vagina regulates itself, and douching or spraying, changes the equilibrium.
â€¢ Urinate before and after sexual activity: Urinating right after sex can help prevent the spread of faecal bacteria to the bladder and thus reduce the risk of UTIs. Men should pass urine each time after the sexual intercourse.
Here are the five most effective bladder infection remedies:
â€¢ Drink more water: Have at least 2 litres of water every day. Water flushes out the bacteria in your bladder, helping to eliminate the infection faster. It also dilutes your urine, so urination may be less painful.
â€¢ Antibiotics: Antibiotics kill the bacteria causing the bladder infection. Antibiotics may not always be needed. In some cases, a minor bladder infection can resolve on its own. It might cause symptoms for a day or two, but with increased hydration and urination, it may pass.
â€¢ Heating pads: Putting low heat across your abdominal region or back may soothe the dull ache that sometimes occurs during bladder infections. This can be especially helpful if medications aren't enough to ease your discomfort.
â€¢ Appropriate dress: Bacteria thrive in warm and moist environments.
Tight jeans and other snugly fitting clothes can trap moisture in your most delicate areas, making them a breeding ground for bacteria. Wearing loose, casual clothing that allows your skin to breathe can keep the bacteria in your urinary tract at bay. (ANI)Region: IndiaGeneral: Health
