Ludhiana hosts seminar on Sufism

Ludhiana, Sep 19(ANI): Ludhiana recently played host to a national seminar on Sufism. This time, the theme was the influence of Sufism on modern times.

The Sahitaya Academy of New Delhi and the Punjab Sahitaya Academy organized the seminar.

The seminar also focused on the ‘pain of separation from God’ and intellectuals, poets and Sufi singers.

“Sufism says that God, whom a man looks for all over, is within him. And once he realizes this fact, he will be free of his ego and will find happiness,” said Vaasthe Mohi, a Sindhi poet from Ahmedabad.

While, Gulshan Majith, a poet from Jammu and Kashmir, said: “When God is everything, so what is the importance of religion and caste discrimination, this is the message of Sufism. Shaivaism, Buddhism and Sufism give same message to the world and consider this world as the manifestation of that supreme power and do not make a distinction with the other. There are no boundaries. Everybody in this world is equal for God.”

The participants also put forth the argument that many Punjabi poets make use of themes from popular Punjabi culture. r. Chandraprakash Deval, a poet from Rajasthan, said Sufism is the paramount method to fight terrorism.

“Sufism is the best way to fight terrorism. If the minds of people can be changed, they will start respecting other religions, humanity and the feeling of brotherhood and secularism will increase, terrorism will be finished then. So to fight terrorism it is important to popularize the way shown by Sufism, adopt and follow that way and spread the feeling of brotherhood,” Deval said.

Sufi singer Balbir Kaur, who also teaches singing at Guru Nanak College in Ludhiana, held the audience spellbound and she also highlighted that school students must be made aware of the great cultural heritage, traditional folk art and literature of the Sufi saints, to promote Punjabi language.

Associating Sufism with any one religion is against its very basic tenets. Underlining this basic fact, renowned Sufi singers Idrim Khan and Skakur Khan from Rajasthan sung the verses of Bulle Shah, Guru Nanak, Kabir and Sajjan Shah. By Karan Kapoor (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)

Study on sheep shows link between personality, survival, and reproductive success

Washington, September 16 (ANI): Canadian researchers have established a link between personality, survival, and reproductive success by carrying out a study on male bighorn sheep.

Denis Reale, a professor in the Department of Biological Sciences at UQAM and Canada Research Chair in Behavioural Ecology, says that the new study offers insight into personality differences in animals and humans, from an evolutionary perspective.

Since 1969, several teams of researchers have been studying this population of bighorn sheep in Alberta, Canada. They have collected considerable data over the years.

Working in collaboration with researchers from the University of Sherbrooke and the University of Alberta, Reale identified the rams in terms of boldness and docility.

The researchers then conducted paternity tests to determine which rams were reproducing.

They point out that in a system like that of bighorn sheep where there is strong competition among the males for impregnating females, large size and high dominance status are normally key factors in a male’s success.

Males usually attain these conditions in the prime of life, between 6 and 12 years, the researchers say.

However, the paternity tests showed that some young males manage to fertilize females.

The researchers also concentrated on the risk associated with participation in the rut-males can be injured or fall from a cliff in fighting.

Reale and his colleagues hypothesized that the young males that manage to reproduce would be the boldest and most combative, and analysis of the data confirmed it.

However, in exchange for sexual precocity and risk-taking, these rams often die younger than their more docile peers. The latter, instead, invest in the long term, breed later and reach an older age.

Based on their observations, the researchers came to the conclusion that their findings indicate a variation in the personalities and life histories of the population, with two extreme types: one that could be characterised as “live fast and die” and the other as “slow and steady wins the race”.

Depending on their personality, the males managed to breed and to transmit their genes, but in different ways.

The study demonstrates that personality has a direct influence on the lifestyle of individuals.

A research article describing the study has been published in the Journal of Evolutionary Biology. (ANI)

Rooney unlikely to captain Manchester United, says Fergie

London, Sep 12 (ANI): Old Trafford Boss Sir Alex Ferguson has said that ace striker Wayne Rooney is unlikely to captain Manchester United.

Rooney has spoken of his desire to be skipper, but Ferguson prefers defenders or midfielders to lead his side.

“It’s difficult for a forward to be captain. Eric Cantona was because he was such an influence to young players, they idolised him,” The Sun quoted Ferguson, as saying.

“But normally you look at midfielders or defenders. Wayne will always take responsibility, he has a natural desire for that and will always give 100 per cent,” he said. Ferguson insists “we have yet to see the best of Rooney.”

“When players reach 25 they play with authority and bring calmness to their game,” he added. (ANI)

Weight gain in adulthood linked to prostate cancer risk

Washington, Sep 12 (ANI): Body size and weight gain in younger and older adulthood may help weigh a man’s proneness to prostate cancer, according to a study by researchers at the University of Hawaii at Manoa’s Cancer Research Center of Hawaii.

Led by Dr. Brenda Hernandez, the researchers said that the risk varies among different ethnic groups

For the study, the researchers studied the relationship in a multiethnic population consisting of blacks, Japanese, Hispanics, Native Hawaiians and whites, and compared differences among age groups using the Multiethnic Cohort, a longitudinal study of men 45-75 years of age established in Hawaii and California from 1993-1996.

Of the 83,879 men who participated in the study, 5,554 developed prostate cancer.

Overall, men who were overweight or obese by age 21 had a decreased risk of localized and low-grade prostate cancer, according to Hernandez.

Their results suggested that being overweight in older adulthood was associated with increased prostate cancer risk among white and Native Hawaiian men, but a decreased risk among Japanese men.

While excessive weight gain between younger and older adulthood was observed to increase the risk of advanced and high-grade prostate cancers in white men and increase the risk of localized and low-grade disease in black men, it appeared to decrease the risk of localized prostate cancer in Japanese men.

“The relationship of certain characteristics, such as body size, with cancer risk may vary across ethnic groups due to the combined influence of both genes and lifestyle,” said Hernandez.

However, the relationship between body size and prostate cancer risk is not entirely understood.

Excess fat is associated with a number of conditions that contribute to cancer development including low-grade chronic inflammation, insulin resistance, metabolic abnormalities, and hormone imbalances.

These conditions may in turn contribute to more aggressive prostate malignancies.

Ethnic differences in cancer risk may be explained by differences in the distribution of stored body fat that could have a differential effect on the development of prostate cancer.

And the distribution of body fat may influence the specific way that excess fat influences cancer risk.

The study has been published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research. (ANI)

Smugglers using kids as ‘carriers’ on Indo-Nepal border

Kolkata, Sep. 11 (ANI): Smugglers active along the porous Indo-Nepal border are now using children, as ‘carriers’ to smuggle goods like sugar and tobacco.

Hundreds of children, in the age group of six to years, are being hired by the mafia of smugglers to carry out this illegal trade along the Sunauli check point of Uttar Pradesh.

Reportedly, the reliance on children has been so successful in smuggling that the influence of such a modus operandi is even witnessed in West Bengal.

The chosen children are paid around rupees 200 per day for running the errands.

“I travel at least 10 times in a day. I carry five kilograms of sugar in one visit and I get 200 rupees. I also study. I live in Jogiabadi,” said Akhil.

Shree Chand Gupta, President, Indo-Nepal Friendship Organisation contended that it is the poverty stricken parents who are persuading their children.

He added that this trends can turn out to be heinous in the long run if not checked at the right time.

“Today they are carrying sugar but tomorrow they can also smuggle arms and ammunitions on the other side and can work as traitors. Hence officers of both the countries should take a note of this crime as it can also cause a serious threat to the society,” said Gupta.

Physically challenged persons and aged women are also becoming soft targets for smugglers, as they don’t have any regular source of income.

Awareness campaigns in the border villages and schools can put a stop to the malpractice.

“Above all, the customs and the security personnel manning the transit points along the India-Nepal border need to pull up their socks,” Gupta points out. (ANI)

Men’s sweat ‘boosts their attractiveness in the eyes of women’

London, Sept 11 (ANI): A naturally present chemical in men’s sweat may act as a primitive love potion that increases their attractiveness in women’s eyes, says a new study.

The substance is derived from the male sex hormone testosterone.

To reach the conclusion, Tamsin Saxton of the University of St Andrews studied the influence of androstadienone by dabbling a drop of it on the upper lip of 50 women who took part in the evening trial before they “dated” a series of men.

From analyses, researchers found that women of all ages rated the men slightly higher on a scale of attractiveness when given the substance, compared to water or clove oil, but the effect was greatest in younger women aged between 18 and 22, reports The Independent.

“For some of the women we gave them androstadienone and we put it in clove oil solution so they just smelt clove oil. Some of the women had clove oil alone, and the third group had just water so there was no odour at all,” she told the British Science Festival.

“We got the women to mark how attractive they thought the men were on a one to seven scale after they interacted with each man,” she said.

“We found that the women given androstadienone had given slightly higher ratings of attractiveness to the men. That suggested this constituent of sweat does seem to have some kind of impact on attraction,” she told the festival.

“Some people don’t seem to be able to smell it all, some people say it smells OK or a bit sweaty, whereas others say it smells really awful, like babies’ nappies,” Saxton said.

According to the expert, one hypothesis is that it could be a “pheromone”, or chemical messenger that acts between individuals in much the same way that hormones act as messengers within the body.

“It’s something that people investigate on the topic of pheromones. When you talk of animal pheromones, they are involved in very specific reactions,” Saxton said.

“People do value somebody’s natural skin smell and it’s worth bearing in mind that this may be part of your appeal – how you smell naturally,” she told the festival. (ANI)

How addictive drugs influence learning and memory

Washington, Sep 10 (ANI): In a new study on mice, researchers have found why and how the use of addictive drugs take control of reward signals and influence neural processes associated with learning and memory.

The study could help explain how drug-associated memories, such as the place of drug use, drive and perpetuate the addiction.

It is known that the neurochemical dopamine, a key player in the brain’s reward system, is involved in the process of addiction.

Research has indicated that dopamine participates in neural processes associated with learning, such as the strengthening of neuronal connections, called synaptic potentiation.

Evidence has also implicated the hippocampus, a deep-brain structure that is critical for formation of new memories, in the development of drug addiction.

“Although addictive drugs like nicotine have been shown to influence the induction of synaptic potentiation, there has been little or no research in freely moving animals that monitors ongoing induction of synaptic potentiation by a biologically relevant drug dose,” explains senior author Dr. John Dani from the Department of Neuroscience at the Baylor College of Medicine in Houston, Texas.

The researchers recorded from the brains of freely moving mice while applying physiologically relevant concentrations of nicotine, the addictive component in tobacco.

The researchers found that nicotine induced synaptic potentiation correlated with the mice learning to prefer a place associated with the nicotine dose.

Importantly, these effects required a local dopamine signal within the hippocampus.

The finding reinforces the view that dopamine enables memory for specific events.

Overall, the results point to some intriguing possibilities about how drug-associated memories might contribute to behaviors associated with addiction.

“An animal’s memories or feelings about the environment are updated when the dopamine signal labels a particular event as important, new, and salient. Normally these memories help us to perform successful behaviors, but in our study, those memories were linked to the addictive drug.

When specific environmental events occur, such as the place or people associated with drug use, they are capable of cuing drug-associated memories or feelings that motivate continued drug use or relapse,” concluded Dani.

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

Gecko’s tail has a mind of its own

Washington, September 9 (ANI): A new study has found that the gecko tail literally has a mind of its own, as it exhibits not only rhythmic but also complex movements, including flips, jumps and lunges, after it is shed.

Anthony Russell of the University of Calgary (U of C) and Tim Higham of Clemson University in South Carolina carried out the study.

Geckos and other lizards have long been known for their incredible ability to shed their tails as a decoy for predators, but little is known about the movements and what controls the tail once it separates from the lizard’s body.

Although one previous study has looked at movement of the tail after it is severed, no study up to this point has quantified movement patterns of the tail by examining the relationship between such patterns and muscular activity.

“What we’ve discovered is that the tail does not simply oscillate in a repetitive fashion, but has an intricate repertoire of varied and highly complex movements, including acrobatic flips up to three centimetres in height,” said Russell, a biological sciences professor at the U of C.

“An intriguing, and as yet unanswered, question is what is the source of the stimulus is that initiates complex movements in the shed tails of leopard geckos,” said Higham.

“The most plausible explanation is that the tail relies on sensory feedback from the environment. Sensors on its surface may tell it to jump, pivot or travel in a certain direction,” he added.

The ability of an animal, or part of an animal, to move without the active control of higher centres in the brain is well known, but this generally occurs as a result of traumatic physical injury.

Tails of lizards are shed under the animal’s own control.

Because of this, the behaviour of the shed part has adaptive evolutionary importance and its actions are programmed to assist in the owner’s survival.

The movements are coordinated by the part of the spinal cord that is housed in the tail.

The isolated tail serves as a vehicle for studying the ways that nerves and muscles act together to generate controlled but complex outputs in the absence of the influence of the brain.

The new study shows that the signals responsible for movements of the shed tail begin at the very far end of the tail, indicating that there is a control centre located there that is likely overridden by higher centres until the tail is shed, at which point its potential is realized. (ANI)

Musharraf terms his meeting with Saudi King a success

Lahore, Sep 7 (ANI): Former Pakistan President Pervez Musharraf has said that his recent meeting with Saudi King Abdullah was a success.

“I was accorded full protocol during my visit to Saudi Arabia to meet King Abdullah, I deem him as my elder brother and can contact him whenever I want,” a private TV channel quoted Musharraf, as saying.

He said during his visit, he discussed the recent political situation of Pakistan at length with the Saudi king, adding that the king had concerns about the situation in Pakistan.

Talking to the channel, Musharraf said the army operation against the Taliban in Malakand had proven successful.

“The operation was undoubtedly successful. The Pakistan Army has always rendered sacrifices and played a vital role to safeguard the territorial integrity of the country,” he said.

Earlier, the ‘royal’ treatment being given to Musharraf during his Saudi Arabia visit has his opponents worried.

The special treatment has sparked speculations that Riyadh is trying to use its influence to ask the Pakistan Muslim League-Nawaz (PML-N) to shun its demand for Musharraf’s trial under the Article Six of the Constitution.

Sources said King Abdullah sent his special airplane to London to fetch Musharraf.

Reports regarding Saudi Arabia cracking its whip on the PML-N and other anti-Musharraf parties has probably forced PML-N to come out with clarifications. (ANI)

Oil, trade was big part of Lockerbie bombers release deal, admits Straw

London, Sep 5 (ANI): Britain’s Justice secretary Jack Straw has admitted for the first time that trade and oil deals with Libya played a very big part in the handling of the Lockerbie bomber’s case.

He said trade was a major influence on his decision to include Abdelbaset Al Megrahi in a prisoner transfer agreement with Libya signed two years ago, just as BP was seeking a multi-billion pound deal there.

In January 2008, Libya ratified a $900 million (£551 million) oil deal with BP.

When asked in the interview if trade and BP were factors, Straw admits: “Yes, (it was) a very big part of that. I’m unapologetic about that… Libya was a rogue state.

“We wanted to bring it back into the fold. And yes, that included trade because trade is an essential part of it and subsequently there was the BP deal.”

The admission directly contradicts Prime Minister Gordon Brown’s insistence only days ago that oil deals were not a factor in Megrahi’s release, The Telegraph reports.

Straw also suggested that Kenny MacAskill, the Scottish Justice Minister, released the terminally ill bomber on compassionate grounds earlier than the British Government would have done.

Brown has been accused of putting Britain’s trade interests before justice for the Lockerbie victims.

Megrahi, who is suffering from prostate cancer, was freed last month by Scotland on compassionate grounds after it was said he was only months from death. Last night it emerged he has been moved out of intensive care.

Straw also claims that Brown had nothing to do with his change of heart over the prisoner transfer agreement, adding: “I certainly didn’t talk to the PM. There is no paper trail to suggest he was involved at all.”

A spokesman for BP said the company had raised concerns with the Government about the slow progress in concluding the PTA, but denied mentioning Megrahi. (ANI)

Enhancement of India, Russia trade ties

Moscow, Sep 3 (ANI): President Pratibha Devisingh Patil has expressed a desire to enhance bilateral trade ties with Russia.

While addressing a gathering of expatriate Indians and some prominent Russians during the course of her five-day visit, Patil said, the only area where India-Russia relationship is lagging is in the field of bilateral economic cooperation.

“When I look at our relationship, if there is anywhere I feel we are lagging behind, it is in the field of bilateral economic cooperation. For two economies with GDP’s of this size, economic structures that only point to our strong complementarities, close political ties, at all levels of government and strong desire of political leadership of both the sides to foster closer ties, India-Russia bilateral trade and investment ties remain much too modest,” Patil added.

Acknowledging the work done by the expatriate Indian community towards enhancing ties between both the countries, Patil said, “All of you have been working in some capacity or the other with India-Russia collaborators projects. It is your work that has provided the building blocks to the India-Russia strategic partnership.”

Reportedly, Russia is keen to double the trade with India to 10 billion dollars by 2010 and cement Indo-Russian relations despite trade with India lagging far behind Moscow’s economic ties with the European Union and China.

Russia sees India, a staunch ally of the erstwhile Soviet Union during the Cold War era, as an important partner to expand Russian influence in Asia, though Moscow and New Delhi have bickered over delays in the delivery of Russian military hardware.

Russia is aiding in the setting up of two 1,000-megawatt nuclear reactors at Kudankulam as part of a deal signed in 1988. Russia agreed in 2008 to build four more reactors at the site. By Pankaj Choudhary (ANI)

Prince Charles accused of ‘abusing his position’ to influence planning process

London, Sep 2 (ANI): A senior architect in Britain has accused Prince Charles of “abusing his position” to influence planning decisions.

Ruth Reed, the first woman president of the Royal Institute of British Architects (RIBA), claims that the Prince of Wales used his royal status to interfere in the “democratic process”.

She also accused him of writing letters “behind the scenes” to display his opinions on certain architects and building projects.

“It is unfortunate if anybody uses their position in public life to exert undue influence on a democratic process such as planning,” the Telegraph quoted her as telling BBC Radio Four’s Front Row.

She added: “There appears to be evidence that he has written behind the scenes both about planning applications and also about the appointment of particular architects, which would be an abuse of his position, definitely.”

However, the Clarence House has declined to comment on the allegations. (ANI)

Musharraf’s ‘royal’ treatment in Saudi Arabia worries his opponents in Pak

Islamabad, Sep.2 (ANI): The ‘royal’ treatment being given to former Pakistan President General Pervez Musharraf during his Saudi Arabia visit has his opponents worried.

The special treatment has sparked speculations that Riyadh is trying to use its influence to ask the Pakistan Muslim League-Nawaz (PML-N) to shun its demand for Musharraf’s trial under the Article Six of the Constitution.

Sources said King Abdullah sent his special airplane to London to fetch Musharraf.

Reports regarding Saudi Arabia cracking its whip on the PML-N and other anti-Musharraf parties has probably forced PML-N to come out with clarificatiobns.

A PML-N spokesman denied reports regarding Saudi putting pressure on PML-N chief Nawaz Sharif.

“There has been no official message from the Saudi family to Mian Nawaz Sharif in this regard,” The Dawn quoted a PML-N spokesperson, as saying.

One of Musharraf’s close aides, Barrister Mohammad Ali Saif, who claims to be the former Army General’s spokesman, said the PML-N should think once again before demanding Musharraf’s prosecution, and see what kind of treatment he is receiving in Riyadh.

“The PML-N should see and understand how the former president is being treated by the Saudi government and forget about his (Musharraf) trial for treason” Saif said.

When asked that whether the Saudi Government has actually given Musharraf a guarantee of not being tried, Saif said : “I don’t know anything about this, but there is little possibility of Gen Musharraf facing trial only because the PML-N is asking for that.”

“I am not aware of this, but the way the former president is being treated in the kingdom means he cannot be touched in Pakistan,” he added. (ANI)

‘Ex-Nepal prince involved in fake currency racke’

New Delhi, Aug. 31 (ANI): Nepali nationals caught by the Madhya Pradesh ATS in connection with fake currency racket have revealed Nepal’s former prince Paras’s link to India’s most wanted terrorist Dawood Ibrahim.

Paras is the son of the former Nepal king Gyanendra, who has now taken refuge in Singapore.

The revelations came during the interrogation of two Nepali nationals, who were caught while trying to smuggle in the fake currency notes into India.

They further revealed that a prominent minister’s son Yunus Ansari was working as as the conduit between King Gyanendra’s son Paras and underworld kingpin Dawood Ibrahim, who between them have been pushing crores of fake currency into India.

According to sources, Dawood manages the printing and manufacture of the fake currency, while Paras is responsible for the transit of the money from other countries into Nepal and then its flow into India.

Paras reportedly used his influence to ensure the money reached the transit points on the India-Nepal border without any hitch. (ANI)

Aguilera credits hubby for helping her overcome abusive past

Washington, Aug 29 (ANI): Pop singer Christina Aguilera paid an emotional tribute to her hubby Jordan Bratman in a recent TV interview, crediting him for helping her overcome her abusive past.

Aguilera, 28, and music marketing executive Bratman, 32, who are parents to 19-month-old son Max, will be married four years in November.

And the singer insists that it is only because of Bratman’s loving influence that she has been able to conquer her fears after growing up with an abusive father.

“I grew up not having any real male perspective or role model and Jordan just continuously makes me fall deeper and deeper in love with him everyday,” Contactmusic quoted her as telling E! Online.

“He just exudes such love and is such a great father to Max that it just makes me the happiest woman alive.

“I’m just lucky to have him in my life… every couple has times when they disagree, but I never allow any arguments to escalate in front of Max,” she added. (ANI)

Scientists discover new connections that may help predict Indian monsoon’s intensity

Washington, August 28 (ANI): In a new research, scientists have determined that subtle connections between the 11-year-solar cycle, the stratosphere and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect much of the globe, an understanding which would help in predicting the intensity of the Indian monsoon.

“It’s been long known that weather patterns are well-correlated to very small variations in total solar energy reaching our planet during 11-year solar cycles,” said Jay Fein, program director in the National Science Foundation (NSF)’s Division of Atmospheric Sciences, which funded the research.

“What’s been an equally long mystery, however, is how they are physically connected. This remarkable study is beginning to unravel that mystery,” he added.

An international team of authors led by the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, used more than a century of weather observations and three powerful computer models to tackle one of the more difficult questions in meteorology: if the total energy that reaches Earth from the Sun varies by only 0.1 percent across the approximately 11-year solar cycle, how can it drive major changes in weather patterns on Earth?

The answer, according to the study, has to do with the Sun’s impact on two seemingly unrelated regions.

Chemicals in the stratosphere and sea surface temperatures in the Pacific Ocean respond during solar maximum in a way that amplifies the Sun’s influence on some aspects of air movement.

This can intensify winds and rainfall, change sea surface temperatures and cloud cover over certain tropical and subtropical regions, and ultimately influence global weather.

“The Sun, the stratosphere, and the oceans are connected in ways that can influence events such as winter rainfall in North America,” said NCAR scientist Gerald Meehl, the lead author of the paper.

“Understanding the role of the solar cycle can provide added insight as scientists work over the next decade or two toward predicting regional weather patterns,” he added.

The Indian monsoon, Pacific precipitation and sea surface temperatures, and other regional climate patterns are largely driven by rising and sinking air in Earth’s tropics and subtropics.

The new study could help scientists use solar-cycle predictions to estimate how that circulation, and the regional climate patterns related to it, might vary over the next decade or two. (ANI)

New model of quantum gravity may rewrite Einstein’s theory of general relativity

Washington, August 25 (ANI): Scientists at Texas A and M University in the US have developed a controversial new model of quantum gravity, which might reproduce Albert Einstein’s theory of general relativity.

The theory, which Einstein developed in the early 20th century, says that matter curves spacetime, and it is this curvature which deflects massive bodies – an effect that we interpret as the influence of gravity.

The theory has been tested to extremely high accuracy and without it, our satellite global positioning system would be off by about 10 km per day.

Despite the success of general relativity, one of the most important problems in modern physics is finding a theory of quantum gravity that reconciles the continuous nature of gravitational fields with the inherent ‘graininess’ of quantum mechanics.

Recently, Petr Horava at Lawrence Berkeley Lab proposed such a model for quantum gravity that has received widespread interest, in no small part because it is one of the few models that could be experimentally tested.

In Horava’s model, Lorentz symmetry, which says that physics is the same regardless of the reference frame, is violated at small distance scales, but remerges over longer distance scales

The team at Texas A and M, which includes Hong Lu, Jianwei Mei and Christopher Pope, report their investigations into how the modifications proposed in Horava’s theory will broadly affect the solutions of general relativity.

Lu and his team’s calculations suggest that Horava’s model only reproduces general relativity on unobservable scales, “larger than the size of the Universe”.

The research team’s paper is an important contribution to testing the Horava model and shows that a good deal of work remains to understand its full implications. (ANI)

Different types of booze impact desire for food differently

Melbourne, August 25 (ANI): The type of alcoholic drink you consume may have an impact on your desire for food, suggests an Australian study.

Dr. Anna Kokavec, a research psychologist at La Trobe University in Bendigo, found that the additional nutritional content of various alcoholic beverages influence the body’s reaction to alcohol, reports ABC Science.

The lead author, along with her team, measured the effect of red wine, white wine, light beer or regular beer on the hypothalamic-pituitary adrenal (HPA) axis, which is responsible for the synthesis of the steroid hormones cortisol and dehyrdoepiandrosterone sulfate (DHEAS).

Kokavec said that DHEAS and cortisol, commonly known as a stress hormone, influence appetite, adding: “We need a sufficient release of cortisol to make us feel hungry.”

She found that cortisol levels went down in participants after the consumption of alcohol, and decreased their appetite despite having fasted for half a day.

But DHEAS levels varied depending on what type of alcohol was consumed.

The DHEAS levels initially took a dip for those who took beer before going up, resulting in an eventual increase in hunger.

Kokavec said: “Beer completely confuses the system.”

Consumption of red wine was also observed to have led to an increased appetite.

But, unlike beer and red wine, white wine completely switched off the HPA axis, indicating hunger remained low.

The study has been published in the journal Pharmacology, Biochemistry and Behaviour. (ANI)
