Study: Children spending more time with screen media than books

What’s happening to the bedtime story? A study carried about by Common Sense Media has found that American children aged between 0 and 8 now spend more than triple the amount of time watching television than reading book

s. or having stories read to them. The research also looked at the growing use of mobile devices by children.

Anyone with a young child, niece or nephew will know the ease with which they take to devices like smartphones and tablets. Within minutes they seem to have the hang of it, swiping, pinching, and possibly even purchasing a few things they shouldn’t be.

A recent study by Common Sense Media looked at the use of mobile devices by children in the US, as well as other screen media in the home. It found that many children now spend more than triple the amount of time engaged with screen media than they do with books. Although the use of mobile devices is increasing among children, it’s the television that still dominates the lives of many.

According to the results of the study, 53 percent of all children have access to a mobile device such as a smartphone or tablet computer, with 20 percent of all parents having downloaded apps specifically for their children to use.

Apparently 10 percent of 0- to 1-year-olds have used a mobile device, though beyond dribbling over it and sitting on it, it’s not certain what benefit they actually get from it.

In a typical day, the results found that 11 percent of all 0- to 8-year-olds use a mobile device, spending an average of 43 minutes doing so.

Computers are also widely used, with 22 percent of 5- to 8-year-olds using one at least once a day, and 46 percent at least once a week.

The study also found that:

- there exists a significant digital divide. Although 72 percent of 0- to 8-year-olds have a computer at home, access to it ranges from 48 percent among those from low-income families (under $30,000 a year) to 91 percent among higher-income families (over $75,000 a year).

- an “app gap” has also developed. Only 14 percent of lower-income parents have ever downloaded apps for their children to use, compared to 47 percent of higher-income parents. Thirty-eight percent of lower-income parents say they don’t even know what an app is, compared to just 3 percent of higher-income parents.

- In a typical day, the study found, 47 percent of babies aged between 0 and 1 watch television or DVDs, and of those, an average of almost two hours (1hr 54mins) is spent doing so.

- Almost one in three (30 percent) of children aged between 0 and 2 has a television in their bedroom.

- Children aged between 0 and 8 spend an average of 1hr 44mins a day watching television or DVDs, compared to only 29 minutes reading books or having stories read to them.

The purpose of Common Sense Media’s study is to provide those concerned with promoting healthy child development – such as educators, pediatricians and public health advocates – with reliable information about media use among children.

Almost 1,400 parents with children aged between 0 and 8 were questioned in the study.

Just be nice to others to make the world full of kind people

London, September 20 (ANI): Spreading altruism through social networks can make people across the world kind to one another, says an expert.

Nicholas Christakis, of Harvard Medical School in Boston, has observed in a study that one’s kindness can turn a friend kind to someone else he/she knows.

To demonstrate this, Christakis designed a cooperation game in which 120 students were organised into groups of four, and asked to give money to their group.

The game lasted five rounds, and after each round the students were reorganised so that no two appeared in the same group twice.

At the end of each found, the participants were told how much the others in their group had given.

Christakis observed that if someone gave a dollar more than the predicted group average, the others in that group gave approximately 20 cents more than expected in the next round.

The altruism persisted into the third round, said the researcher.

A separate study conducted by Christakis’s team showed that cooperative behaviour spreads to three degrees of separation, from friend to friend to friend, reports New Scientist.

Based on their observations, Christakis and colleagues came to the conclusion that a person who is popular and well connected could have a special role to play, as his/her compassionate acts could resonate further through the network, and he/she was also more likely to benefit from other people’s kindness.

HIV uses several routes to escape immune system pressure

Washington, September 19 (ANI): Researchers at the Emory Vaccine Center have shown that HIV relies upon a number of strategies rather than use any preferred escape route to escape immune system pressure.

The human immune system has the ability to temporarily overpower HIV in early infection.

Studies conducted in the recent past have shown that most newly infected patients develop neutralizing antibodies. These are blood proteins that glob onto the virus and would allow patients to defend themselves – if they were facing only one target.

However, the problem occurs when HIV mutates, and disguises itself enough to get away from the antibodies. The virus eventually wears down the immune system into exhaustion.

The Emory team’s findings attain significance as they suggest that even if any scientist succeeds in identifying a vaccine component that can stimulate neutralizing antibodies, HIV’s capacity for rapid mutation could still be a confounding factor.

Dr. Cynthia Derdeyn, associate professor of pathology at Emory University School of Medicine, Emory Vaccine Center and Yerkes National Primate Research Center, says that a single type of neutralizing antibody may not be enough to contain HIV.

“These neutralizing antibodies work really well – they hit the virus fast and hard. But so far, every time we look, the virus escapes,” she says.

During the study, the researchers took blood samples from the participants a few weeks after infection occurred, and then later as two participants’ immune responses continued.

They isolated individual viruses over the first two years of HIV infection, and tested how well the patients’ own antibodies could neutralize them.

“In one patient where we had very early samples, there was evidence that neutralizing antibody came up within weeks, and that’s earlier than what was previously thought,” Derdeyn says.

In both patients, some viruses mutated part of their outer proteins so that after the mutation, an enzyme would be likely to attach a sugar molecule to it.

Though the sugar molecule interferes with antibody attack, this tactic, known as the “glycan shield”, was not observed in all cases.

Other viruses mutated the part of the outer protein that the neutralizing antibodies stick to directly. In both patients, many changes in the virus’ genetic code were necessary for escape.

“We need to understand early events in the immune response if we are going to figure out what a potential vaccine should have in it. What we can show is that even in one patient, several escape strategies are going on,” Derdeyn says.

According to her, that means that in order to be immune to HIV infection, someone may need to have several types of neutralizing antibodies ready to go.

Seeing how the virus mutates will allow researchers to choose the best parts to put in a vaccine, she says.

The results are online and scheduled for publication in the September issue of the journal Public Library of Science Pathogens.(ANI)

Young age at first drink can turn under-15s into alcoholics

Washington, Sept 19 (ANI): Drinking at young age may affect genes linked to alcoholism and make youngsters vulnerable to severe problems, says a new study.

The study led by Dr Arpana Agrawal, from Washington University School of Medicine in St. Louis, revealed that the younger an individual was at first drink, the greater the risk for alcohol dependence and the more prominent the role played by genetic factors.

“There seemed to be a greater genetic influence in those who took their first full drink at a younger age,” said Agrawal.

“That’s very consistent with what has been predicted in the literature and in the classification of types of alcohol dependence, but we present a unique test of the hypothesis,” she added.

During the study, the researchers studied 6,257 adult twins from Australia and measured the extent to which age at first drink changed the role of heritable influences on symptoms of alcohol dependence.

The study showed that when twins started drinking early, genetic factors contributed greatly to risk for alcohol dependence, at rates as high as 90 percent in the youngest drinkers.

The team also found that those who were 15 or younger when they started drinking tended to have a greater genetic risk for alcohol dependence.

However, some who were 16 or older before they took their first drink later became alcohol dependent, but their dependence was related more to environmental factors.

“Something about starting to drink at an early age puts young people at risk for later problems associated with drinking,” Agrawal says.

“We continue to investigate the mechanisms, but encouraging youth to delay their drinking debut may help.

“Some early-onset drinkers do not develop alcohol problems and some late-onset drinkers do – we are working on why that is the case, but it is important to note that this is one risk factor among many and does not determine whether a person will, or will not, develop alcohol dependence.

“But age at first drink is a well-known risk factor, and there have been two main hypotheses about why:

One has been that common genetic and environmental factors contribute both to the risk for alcohol dependence and to the likelihood a person will be younger when consuming their first drink,” she added.

The study will be published Alcoholism: Clinical and Experimental Research. (ANI)

Britons spend 1 month of their lives looking for TV remote!

London, Sept 18 (ANI): Britons waste one month of their lives searching for the television remote control, a new study has found.

After studying 4,000 individuals, the researchers found that the average viewer loses it an average of 3.2 times a week and spends more than four minutes looking for it each time, reports The Scotsman.

That means each week Brits spend 15 minutes hunting for the device.

Kathryn Drought, of Sky, who led the study to launch the broadcaster’s Free Weekend Pass, said: “The remote control is such a well-used item in the nation’s homes.

“It’s one of those things we’re forever trying to find – normally down the back of the sofa.

“TV plays such a big part in our lives. It’s not surprising who is in control of the remote is such a hot household topic.”

Three in ten volunteers admitted hiding the remote from a partner or housemate, and 17 per cent have thrown it at someone in a fit of “remote rage”, the study found. (ANI)

Negative public opinion about foreign countries an early warning signal for terrorism

Washington, September 18 (ANI): People’s negative views toward the leadership and policies of other countries may be an indication that a terrorist act may be carried out, say researchers.

Alan Krueger, a Princeton University economist, and Jitka Maleckova, of Charles University in the Czech Republic, came to this conclusion after analysing public opinion polls and terrorist activity in 143 pairs of countries.

Writing about their findings in the journal Science, the researchers say that there is a strong relationship between attitudes expressed toward a foreign country — indicated in surveys on foreign leaders’ performance-and the occurrence of terrorism against that country.

“Public opinion appears to be a useful predictor of terrorist activity,” said Krueger, the Bendheim Professor in Economics and Public Policy.

“This is the first study to relate public opinion across countries to concrete actions such as terrorism,” he added.

He pointed out that the notion that public attitudes can contribute to terrorism has been inadequately explored to date.

According to him, the study’s findings attain significance as they suggest that public opinion may provide a valuable early warning signal of terrorism, and help researchers better understand the causes of terrorism.

The researchers carried out their study by mining public opinion polls of residents in 19 countries in the Middle East and northern Africa conducted by Gallup.

They asked the respondents whether they approved of the job performance of the leaders of nine large countries.

According to the researchers, the countries selected for the study are world powers in terms of size, population or military strength, are the United States, Canada, China, France, Germany, India, Japan, Russia and the United Kingdom.

The opinions, both positive and negative, were linked to the number of terrorist attacks conducted against the nine world powers by people from the 19 countries between 2004 and 2008. The terror attacks were compiled by the National Counterterrorism Center.

Based on the findings, Krueger says that there is not a direct connection between poverty and terrorism, contrary to a popular view.

He adds that economic status has more to do with target countries than it does with the states where the attacks originate.

He says that countries with advanced economies as well as a high degree of civil liberties are most likely to be the targets of terrorism.

The researchers admits that the study does not explain whether terrorists act in response to public opinion or whether they are simply reacting just like the larger public to external events.

However, he insists that, in either case, public opinion surveys can provide a powerful indication of the likelihood of terrorist activity.

Krueger believes that greater disapproval of another country’s leaders or policies may result in more terrorist acts because it increases the number of people who provide material support and encouragement for terrorism, and increases the number of people interested in joining cells and carrying out terrorist acts themselves.

Natural hydrogel may boost spinal cord healing

Washington, Sep 18 (ANI): A jab of biomaterial gel into a spinal cord injury site may significantly improve healing, according to researchers at the Barrow Neurological Institute at St. Joseph’s Hospital and Medical Center.

Dr. Mark Preul and Dr. Alyssa Panitch have found in a study that injection of an engineered hydrogel made up mainly of hyaluronic acid (a naturally-occurring body substance) into the spinal cord injury site decreases scarring, and promotes a realignment of the spinal cord fibres around the injury site.

The hyaluronic acid, which forms a scaffold-like configuration may help to structurally stabilize the spinal cord injury site.

The researchers traced cells in the brain stem after injury, and found much higher levels in the hydrogel treated animals as compared to animals that did not receive the treatment, and approached nearly normal levels.

Treated animals had higher functional scores than their non-treated counterparts.

“Spinal cord injury is devastating to civilian and military populations – especially to the young. There has been little progress toward paradigms of regeneration and few results that show real, sustained functional recovery. We’ve been so pre-occupied with regeneration, but that is a highly complicated and difficult to define goal. This project is a synergy of neurosurgeons and bioengineers that attempts repair of the SCI lesion cavity using a tissue-engineering biomaterials approach,” says Preul.

He added that the team aimed at finding ways to structurally allow the body to better heal itself.

“In this project we did not add anything to the hyaluronic acid. It may be that adding growth factors or cells into the gel matrix may allow even better results,” he said.

Preul said that the results show “we may be on a practical path that can give hope to the many people who suffer this sort of injury.”

The work was presented at the Annual Meeting of the American Association of Neurological Surgeons in San Diego where it won the Synthes Prize for Spine Research. (ANI)

Vaccine for urinary tract infections comes closer to reality

Washington, Sept 18 (ANI): A simple vaccine may soon be available to protect against urinary tract infections, thanks to researchers from University of Michigan.

The study conducted over mice showed that the vaccine prevented infection and produced key types of immunity.

It alerts the immune system to iron receptors on the surface of Escherichia coli bacteria that perform a critical function allowing infection to spread.

Administered in the nose, it induces an immune response in the body’s mucosa, a first line of defense against invading pathogens. The response, also produced in mucosal tissue in the urinary tract, should help the body fight infection where it starts.

The researchers used novel systematic approach, combining bioinformatics, genomics and proteomics, to look for key parts of the bacterium that could be used in a vaccine to elicit an effective immune response.

The team, led by Dr. Harry L.T. Mobley, screened 5,379 possible bacterial proteins and identified three strong candidates to use in a vaccine to prime the body to fight E. coli.

Mobley’s team is currently testing more strains of E. coli obtained from women treated at U-M.

If the robust immunity achieved in mice can be reproduced in humans, it could be the first ever vaccine for urinary tract infections.

Most of the strains produce the same iron-related proteins that can be vaccine targets, an encouraging sign that the vaccine could work against many urinary tract infections.

The findings are published in the open-access journal PLoS Pathogens. (ANI)

Scientists find meteorite that came from innermost asteroid belt between Mars and Jupiter

Washington, September 18 (ANI): In a very rare finding, scientists have discovered an unusual kind of meteorite in the Western Australian desert and have uncovered that it came from the innermost main asteroid belt between Mars and Jupiter.

Meteorites are the only surviving physical record of the formation of our Solar System.

However, information about where individual meteorites originated, and how they were moving around the Solar System prior to falling to Earth, is available for only a dozen of around 1100 documented meteorite falls over the past two hundred years.

According to Dr Phil Bland from the Department of Earth Science and Engineering at Imperial College London, the lead author of the study, “We are incredibly excited about our new finding. Meteorites are the most analysed rocks on Earth, but it’s really rare for us to be able to tell where they came from.”

The new meteorite, which is about the size of cricket ball, is the first to be retrieved since researchers from Imperial College London, Ondrejov Observatory in the Czech Republic, and the Western Australian Museum, set up a trial network of cameras in the Nullarbor Desert in Western Australia in 2006.

The researchers aim to use these cameras to find new meteorites, and work out where in the Solar System they came from, by tracking the fireballs that they form in the sky.

The new meteorite was found on the first day of searching using the new network, by the first search expedition, within 100m of the predicted site of the fall.

The meteorite appears to have been following an unusual orbit, or path around the Sun, prior to falling to Earth in July 2007, according to the researchers’ calculations.

The team believes that it started out as part of an asteroid in the innermost main asteroid belt between Mars and Jupiter.

It then gradually evolved into an orbit around the Sun that was very similar to Earth’s.

The new meteorite is also unusual because it is composed of a rare type of basaltic igneous rock.

According to the researchers, its composition, together with the data about where the meteorite comes from, fits with a recent theory about how the building blocks for the terrestrial planets were formed.

This theory suggests that the igneous parent asteroids for meteorites like today’s formed deep in the inner Solar System, before being scattered out into the main asteroid belt.

Asteroids are widely believed to be the building blocks for planets like the Earth, so the new finding provides another clue about the origins of the Solar System. (ANI)

Genes controlling insulin ‘alter’ body clock

Washington, Sept 18 (ANI): Scientists at University of California, San Diego have identified certain insulin-regulating genes that can also alter the timing of the body clock.

They said that the findings can lead to new approaches to treating disorders such as metabolic syndrome that can result, at least in part, from chronic disruption of the sleep-wake cycle.

“People knew that the clock regulates many different processes, but what they didn’t realize what that when you tweak those processes, it feeds back and alters the clock,” said Steve Kay, Dean of the Division of Biological Sciences at the University of California, San Diego, who led the study along with John Hogenesch of the University of Pennsylvania.

A molecular clock controls daily physiological rhythms in many types of cells, even cells grown in culture.

By engineering cultured cells to glow yellow when a particular clock gene switched on, the team made the cycle visible. They then interfered with every human gene to see which would shift the clock. They found that hundreds altered the timing.

“We just suddenly discovered 350 new genes that affect the clock that weren’t known before,” Kay said.

However, subsequent screening to confirm the genes’ effect on a second clock gene narrowed the list to 200.

Seven genes involved in insulin control also influenced the rhythms of the clock.

“What came out very strongly was this close relationship between circadian regulation and insulin signalling. There’s a reciprocal relationship between circadian dysfunction and metabolic dysfunction,” said Kay.

The researchers suggest that genetically altered mice with malfunctioning clocks become obese and develop diet-induced diabetes.Understanding this close relationship between circadian regulation and metabolic homeostasis should provide novel ways of identifying new therapies for metabolic disease,” Kay added.

The study appears in journal Cell. (ANI)

Weight loss can prevent kidney disease progression in obese patients

Washington, Sept 18 (ANI): Shedding extra pounds can preserve kidney function in obese people with kidney disease, according to a new study led by Indian origin scientist from Cleveland Clinic.

Weight loss can improve a number of health problems, like it can improve control of diabetes, lower blood pressure and cholesterol levels, and reduce the effects of heart disease.

During the study, Dr Sankar Navaneethan, and his colleagues analysed the studies that examined the effects of weight loss interventions in obese kidney disease patients.

It showed that weight loss attained through diet and exercise reduces proteinuria (excess excretion of protein in the urine-a hallmark of kidney damage) and may prevent additional decline in kidney function in obese patients with kidney disease.

Studies also showed that surgical interventions normalize the filtration rate of the kidneys in obese patients with high filtration rates (a risk factor for the development of kidney disease).

While the findings imply that weight reduction may prevent the progression of kidney disease in obese kidney disease patients, the authors noted that there were only a small number of studies available for analysis and additional high-quality long-term studies on this topic are needed.

The study appears in Clinical Journal of the American Society Nephrology. (ANI)

Stem cell transplantation may correct rare genetic disorder in kids

Washington, Sep 18 (ANI): Scripps Research Institute scientists have offered new hope for parents whose children suffer from the rare genetic disorder ‘cystinosis’ by showing through an experiment on mice that stem cell transplantation can successfully correct the defect.

“After meeting the children who suffer from this disease, like an 18-year-old who has already had three kidney transplants, and the families who are desperately searching for help, our team is committed to moving toward a cure for cystinosis, a lysosomal storage disorder. This study is an important step toward that goal,” said principal investigator Stephanie Cherqui.

In the study, the researchers used bone marrow stem cell transplantation to address symptoms of cystinosis in a mouse model.

The procedure virtually halted the cystine accumulation responsible for the disease, and the cascade of cell death that follows.

Cystine is a by-product of the break down of cellular components the body no longer needs in the cell’s “housekeeping” organelles, called lysosomes.

Normally, cystine is shunted out of cells, but in cystinosis a gene defect of the lysosomal cystine transporter causes it to build up, forming crystals that are especially damaging to the kidneys and eyes.

Cystinosis is a rare but devastating disease affecting children as young as six months, who begin to suffer renal dysfunction, which grows progressively worse with time. Other symptoms include diabetes, muscular disease, neurological dysfunction, and retinopathy.

The only available drug to treat cystinosis, cysteamine, while slowing the progression of kidney degradation, does not prevent it, and end-stage kidney failure is inevitable.

In the new study, the researchers found that transplanted bone marrow stem cells carrying the normal lysosomal cystine transporter gene abundantly engrafted into every tissue of the experimental mice.

This led to an average drop in cystine levels of about 80 percent in every organ.

Not only it prevented kidney dysfunction, there was less deposition of cystine crystals in the cornea, less bone demineralization, and an improvement in motor function.

“The results really surprised and encouraged us. Because the defect is present in every cell of the body, we did not expect a bone marrow stem cell transplant to be so widespread and effective,” says Cherqui.

Cherqui said that adult bone marrow stem cell therapy is particularly well suited as a potential treatment for cystinosis because these cells target all types of tissues.

In addition, stem cells reside in the bone marrow for the duration of a patient’s life, becoming active as needed, a particular benefit for a progressive disease like cystinosis.

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

India needs to liberalise, change policies to attract more FDI: Nazareth (Corrected)

New Delhi, Sep 18 (ANI): Policy analyst Premila Nazareth has emphasised that India needs to liberalise and change its policies to attract more foreign direct investments.

During the release of the annual study of worldwide investment trends by the United Nations Conference on Trade And Development (UNCTAD) in the national capital, Nazareth also blamed the bureaucracy in India for being the main reason for less inflow of FDI.

“FDI policies do not need much changes to increase fund inflows. Policies are fine. The rest of the policies, bureaucracies and regulations are creating problems for people and these are the reasons behind less inflow of FDI. The policies are liberal, but we need to change and liberalise the sectoral policies of various sectors for private investments,” Nazareth said.

Nazareth further said that India and China are being seen as strong contenders for the Global Direct Investment (GDI) due to their emerging economy status.

“India’s position as a recipient country in the global FDI picture is only going to strengthen over the next few years because global investors are now looking more and more the emerging world as a whole. China and India are seen as very strong players, markets with guaranteed growth in a way and this is only going to grow,” Nazareth added. (ANI)

‘Zero tolerance’ policy has zero effect

Washington, Sep 17 (ANI): Amid an ongoing debate about changing the drinking age from 21 to 18 in the US, a Sam Houston State University economist has raised voice against a related law- the “zero tolerance” policy.

Darren Grant studied data from 30,000 fatalities in nighttime accidents involving drivers under 21, and concluded that zero tolerance laws have zero effect.

“Both in terms of the number of accidents and the blood alcohol of the drivers in those accidents, the research consistently showed that zero tolerance laws had no effect. Other factors matter, but not these laws,” said Grant.

Zero tolerance laws became prevalent during the 1990s, when the US Congress threatened to withhold highway funding from states that didn’t comply.

Grant has now said that the logic behind zero tolerance laws is suspect.

“The idea was, since drivers under 21 are not supposed to be drinking, you should be guilty of drunk driving if you are caught driving with any amount of alcohol in your system,” said Grant.

“Because you must sacrifice more to comply with the law, we should expect some people will just give up trying to satisfy the law and drink more,” he added.

But he found that this did not happen.

“Instead, among drivers involved in traffic accidents, there is the same fraction of heavy drinkers, the same fraction of mild drinkers, the same fraction of nondrinkers. It’s just not changing,” he said.

Grant also compared the blood alcohol distributions of involved drivers in the two years before zero tolerance laws were established in each state, and again in the two years after.

It was found that the two distributions were also virtually identical.

“That’s a sign that this law is essentially inert; if it’s affecting the amount of drinking that people do, these distributions should look different,” he said.

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

The pen may be mightier than the keyboard for schoolkids

Washington, September 17 (ANI): It may not be wrong to say that the pen is mightier than the keyboard, for a new study on schoolchildren so suggests.

Virginia Berninger, a University of Washington professor of Educational Psychology, looked at the ability of second, fourth, and sixth grade children to write the alphabet, sentences, and essays using a pen and a keyboard.

“Children consistently did better writing with a pen when they wrote essays. They wrote more and they wrote faster,” said Berninger.

The researcher further said that only for writing the alphabet was the keyboard better than the pen.

Results were mixed for sentences.

However, when using a pen, the children in the three grade levels produced longer essays and composed them at a faster pace.

The study also showed that fourth and sixth graders wrote more complete sentences when they used a pen, and that this ability was not affected by the children’s spelling skills.

The research also showed that many children don’t have a reliable idea of what a sentence is until the third or fourth grade.

“Children first have to understand what a sentence or a complete thought is before they can write one. Talking is very different from writing. We don’t talk in complete sentence. In conversation we produce units smaller and larger than sentences,” Berninger said.

She, however, added: “We need to learn more about the process of writing with a computer, and even though schools have computers they haven’t integrated them in teaching at the early grades. We need to help children become bilingual writers so they can write by both the pen and the computer. So don’t throw away your pen or your keyboard. We need them both.”

She further said: “We need more research to figure out how forming letters by a pen and selecting them by pressing a key may engage our thinking brains differently.” (ANI)

Green tea may help improve bone health

Washington, Sept 17 (ANI): Green tea may help improve bone health, researchers in Hong Kong have reported.

The boffins found that the tea contains a group of chemicals that can stimulate bone formation and help slow its breakdown.

The study has been published in ACS’ Journal of Agricultural and Food Chemistry, a bi-weekly publication.

In the study, Ping Chung Leung and colleagues noted that many scientific studies have linked tea to beneficial effects in preventing cancer, heart disease, and other conditions.

To reach the conclusion, scientists exposed a group of cultured bone-forming cells (osteoblasts) to three major green tea components – epigallocatechin (EGC), gallocatechin (GC), and gallocatechin gallate (GCG) – for several days. They found that one in particular, EGC, boosted the activity of a key enzyme that promotes bone growth by up to 79 percent. EGC also significantly boosted levels of bone mineralization in the cells, which strengthens bones.

The scientists also showed that high concentrations of ECG blocked the activity of a type of cell (osteoclast) that breaks down or weakens bones. The green tea components did not cause any toxic effects to the bone cells, they noted. (ANI)

NSA to convene China Study Group meeting to discuss incursion fallout

New Delhi, Sep.17 (ANI): National Security Advisor M K Narayanan will hold a meeting of the China Study Group – consisting of top officials including Cabinet Secretary K M Chandrasekhar and Secretaries of Defence, Home and Foreign Ministries – here today.

The meeting is expected to take stock of the situation along the Sino-India border, official sources said.

Besides Chandrasekhar, the meeting will be attended by Defence Secretary Pradeep Kumar, Home Secretary G K Pillai and Foreign Secretary Nirupama Rao.

Top officials of the three armed forces and the Intelligence Bureau will also attend the meeting.

The meeting assumes significance in wake of recent reports of incursions by the Chinese army in Ladakh, Sikkim and Arunachal Pradesh, involving the air dropping of expired food canes, painting of rocks red among others.

Another media report said that two Chinese Sukhoi fighters had transgressed into Indian air space last month.

The Indian Air Force, however, says no unscheduled flight inside Indian air space had taken place last month. (ANI)

Atheists ‘more successful at online dating’

London, Sept 16 (ANI): People who don’t believe in god are more likely to achieve success at online dating, according to a new study of opening messages.

Self-effacing men are also more likely to get a reply to their approaches, while nothing turns off potential dates more than textspeak like “ur” and “luv”.

The researchers analysed 500,000 “first contacts” sent by users of OkCupid, the leading US dating website, and found that nearly 42 per cent of messages, which included the word “atheist”, received replies, significantly higher than the average response rate of 32 per cent.

The study also showed that references to “Christian”, “Jewish” and “Muslim” only had a marginal success rate, reports the Telegraph.

Moreover, mentioning “god” in a first approach actually discouraged people from replying.

The research also suggests online daters to avoid making personal compliments too early like “sexy” and “beautiful”, which reduced response rate.

It showed that people who used the words “good taste” or “you mention” in their messages pushed their response rates close to 50 per cent.

In addition, dreary greetings such as “hi”, “hey” and “hello” are far less successful than sparkier openings like “how’s it going” and “what’s up”.

The results of the analysis were published on OkTrends, the dating website’s official blog. (ANI)

Oz women under constant pressure to be ‘yummy mummies’

Melbourne, Sept 16 (ANI): The hype created by celebrity yummy mummies like Angelina Jolie and Jessica Alba has put women under pressure to lose weight quickly after giving birth, reveals a new Australian study.

The study conducted by Deakin University showed that more than one in four women are “usually or always dissatisfied” with their post-baby body.

Researcher Lucia Bongiorno said that the hype created by celebrity yummy mummies has also contributed to an unrealistic ideal.

“People are obsessed with celebrity babies and celebrity pregnancies,” the Courier Mail quoted her as saying.

“Babies have become a must-have sort of item,” she added.

Although the study involving 346 mothers of infants aged 1-12 months compare themselves with their peers with babies and child-free friends, they felt the most pressure to lose post-baby weight from the media.

Moreover, some fathers also pressured their partners not to gain too much weight while pregnant and to lose it quickly after giving birth.

Bongiorno said while mums compared themselves most to peers, their peers were also likely to be influenced by the same media images.

“Both mothers and their peers with new babies, when confronted by media pictures of celebrity mothers such as Bec Hewitt, are saying ‘I’ve got to look like that’,” she said.

“But celebrity mothers typically have nannies and personal trainers … the average mother doesn’t. So such an expectation is unfair on themselves,” she added.

The study will be presented at the Australian Psychological Society conference in Darwin. (ANI)
