European company develops mobile robots that are autonomous and multi-tasking

Madrid (Spain), September 19 (ANI): An European company has developed innovative robots which are mobile, multifunctional, collaborative, autonomous and polyvalent, suitable for a wide range of work from street cleaning and rubbish collection to accompanying elderly people.

According to a report carried out in www.basqueresearch.com, this new generation of robots have been developed by TECNALIA Technological Corporation, and are a part of the European DUSTBOT research project under the remit of the VI European Framework Programme and in which TECNALIA is participating.

These latest generation robots are suitable for the monitoring of large spaces (open and closed), as guides for persons in large shopping areas (indicating to them where a particular shop or product is within a shopping centre), for accompanying elderly people or those with certain disabilities (both at home and outside), thanks to their functions of orientation, navigation, communications with others or tele-assistance centres.

They can also be used as guides in teaching spaces (museums, visitor centres), and for transport, storage and transport and goods deliveries, besides the cleaning of both open and closed surfaces, which have either difficult or easy access.

DUSTBOT has collaborative, multifunctional and autonomous robots that are capable of operating in partially destructured environments/situations based on information provided by a map.

The robots can also facilitate working in large areas, stations, airports and other types of public buildings, without being any obstacle for the activity of these places, given its reduced size, and without being a danger for members of the public, thanks to the novel system for the detection and avoidance of obstacles.

The rail station of the Euskotren company in the Bilbao neighbourhood of Atxuri in Spain was chosen for the public presentation of these devices.

The demonstration of two robot models was undertaken: the DustCart and the DustClean.

The DustCart robot, measuring 1.45 metres high and 70 Kg in weight, has a humanoid form and is designed to interact with the user and for the collection of low demand waste.

The DustClean robot, in the form of a small vehicle and measuring 96 cm high and 250 Kg in weight, cleans streets of dirt and dust. Moreover, both control the quality of air in real time.

“These robots are the solution for cleaning areas of difficult access and for the collection of rubbish at the very front door of, above all, persons who have mobility problems when moving the rubbish to the communal waste containers,” said Inaki Inzunza, Director of the Business Unit at the Tecnalia Technological Corporation.

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.

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)

How some people maintain weight loss, others don’t

Washington, Sep 16 (ANI): Ever wondered how some people successfully maintain a significant weight loss, while others tend to regain the weight? Well, researchers at The Miriam Hospital attribute such tendencies to a difference in brain activity patterns.

The researchers showed that when individuals who had kept the weight off for several years were shown pictures of food, they were more likely to engage the areas of the brain associated with behavioural control and visual attention, as compared to obese and normal weight participants.

The findings of the study suggest that successful weight loss maintainers may learn to respond differently to food cues.

“Our findings shed some light on the biological factors that may contribute to weight loss maintenance. They also provide an intriguing complement to previous behavioral studies that suggest people who have maintained a long-term weight loss monitor their food intake closely and exhibit restraint in their food choices,” said lead author Dr. Jeanne McCaffery.

Long-term weight loss maintenance continues to be a major problem in obesity treatment.

Participants in behavioural weight loss programs lose an average of 8 to 10 percent of their weight during the first six months of treatment, and will maintain approximately two-thirds of their weight loss after one year.

However, despite intensive efforts, weight regain appears to continue for the next several years, with most patients returning to their baseline weight after five years.

The researchers used functional magnetic resource imaging (fMRI) to study the brain activity of three groups- 18 individuals of normal weight, 16 obese individuals (defined as a body mass index of at least 30), and 17 participants who have lost at least 30 lbs and have successfully maintained that weight loss for a minimum of three years.

When the participants were shown pictures of food items after a four-hour fast, it was found that those in the successful weight loss maintenance group responded differently to these pictures compared to the other groups.

Specifically, researchers observed strong signals in the left superior frontal region and right middle temporal region of the brain – a pattern consistent with greater inhibitory control in response to food images and greater visual attention to food cues.

“It is possible that these brain responses may lead to preventive or corrective behaviors – particularly greater regulation of eating – that promote long-term weight control. However, future research is needed to determine whether these responses are inherent within an individual or if they can be changed,” said McCaffery.

The study has been published in the American Journal of Clinical Nutrition. (ANI)

New e-nose can reveal smokers without need for blood, urine tests

London, September 16 (ANI): An electronic nose foil some people’s attempt to deceive their doctors by telling them that they are non-smokers, in order to get cheaper life insurance.

Paul Thomas at the University of New South Wales in Sydney, Australia, has revealed that their invention is a tweaked form of a commercially available e-nose.

The researcher says that it can detect the volatile organic compounds (VOCs) in the breath of a person who had smoked a cigarette.

The e-nose uses an array of 32 sensors whose electrical resistance changes as different VOCs are detected.

During a test, the researchers could correctly identified 37 out of 39 volunteers as either smokers or non-smokers relying upon on the resultant “smellprint”.

Based on their observations, the team came to the conclusion that such e-noses could quickly and reliably reveal smokers without the need for a blood or urine test.

The current method of measuring the carbon monoxide content of exhaled breath to confirm smoking activity picks up a smoker for only a few hours after their last cigarette.

It is even prone to error because it cannot tell whether carbon monoxide in the breath came from other sources such as traffic exhaust fumes.

Insurers are very interested in whether a person applying for health or life insurance smokes – for obvious reasons.

“Some insurance providers don’t ask questions about smoking at all, while others ask the question on an application form but do not require a test as the applicant is expected to answer the question honestly,” New Scientist magazine quoted Kelly Ostler-Coyle, of the Association of British Insurers, as saying.

By making the test simple and reliable, an e-nose could provide doctors with the truth in minutes, according to the researchers.

They, however, admit that their system needs further testing to prove its worth.

“This e-nose idea, whilst of interest, will require larger-scale trials to demonstrate clinical efficacy and patient acceptability before it can be considered for use,” says a spokesman for the UK Department of Health.

A research article describing the innovation has been published in the Journal of Breath Research. (ANI)

Kaira says PPP not following Musharraf’s foreign policy

Islamabad, Sep. 11 (ANI): Pakistan’s Information and Broadcasting Minister Qamar Zaman Kaira has clarified that Asif Ali Zardari Government is perusing its own foreign policies and not those formulated by Pervez Musharraf.

Kaira pointed out that peace in South Asia was not possible without achieving stability in Afghanistan.

The political process should be continued in Afghanistan and removal of foreign forces from Afghanistan would not ensure stability, the Daily Times quoted him, as saying.

Kaira added that Pakistan is the victim of terrorism, and the government would continue to take action against all those who challenge its writ.

Denying any activity by US private security firm Blackwater in Pakistan, he said the PPP would never compromise on issues of national security.

On the question of by-election in Rawalpindi, Kaira said the provincial government had requested the federal government to postpone the election due to the poor law and order situation of the region. (ANI)

Taliban now terrorise 80% of Afghanistan after eight years of war: Report

Kabul, Sep. 11 (ANI): Almost eight years after the war began in Afghanistan in the aftermath of the 9/11 carnage, the Taliban insurgency has spread across 80 percent of the country.

The violent incidents this week have drawn attention to the deteriorating security situation of northern Afghanistan, which had largely remained peaceful so far, the Christian Science Monitor reports.

The northern provinces are facing difficult times as heavy insurgent activity has spread to 80 percent of the country – up from 54 percent two years ago, the report says.

The militants’ focus has shifted to northern parts following continuous pressure from their Pakistani counterparts to attack NATO’s second supply route situated here, it adds.

“[Militants] have been trying to widen the ground for the insurgency in Afghanistan and now they have got momentum. The militants are eager to target this route to prevent a smooth supply chain from northern Afghanistan,” the report quoted Waliullah Rahmani, executive director of the Kabul Center for Strategic Studies, as saying.

Last week’s airstrike targeted two fuel tankers headed to supply NATO troops in Kabul that had been hijacked by the Taliban.

Although the increase in violence is only a recent phenomenon, the conditions had worsened long ago, the report says.

The violence can be linked to districts with large Pashtun populations, whose grievances the government has failed to address – making them sympathetic to the Taliban, who share their ethnicity and language, it adds.

“The districts which are turning violent are those which have had a very recent history of abuses against the Pashtuns.

The government has allowed these conditions to go unaddressed and this is now being addressed by the population by giving shelter to the Taliban and other insurgents,”the report quoted Prakhar Sharma, the head of research at the Center for Conflict and Peace Studies, as saying.(ANI)

Exposure to second-hand tobacco smoke linked to liver disease

Washington, September 11 (ANI): People can develop liver disease even when they are exposed to second-hand tobacco smoke, according to a study.

Scientists at the University of California, Riverside (UCR) have found that exposure to second-hand tobacco smoke can lead to non-alcoholic fatty liver disease (NAFLD), a common disease and rising cause of chronic liver injury wherein fat accumulates in the liver of people who drink little or no alcohol.

For their study, the researchers exposed some mice to second-hand cigarette smoke for a year in the lab, and observed fat build-up in their liver cells, a sign of NAFLD that eventually leads to liver dysfunction.

The researchers focused on two key regulators of lipid (fat) metabolism that are found in many human cells as well: SREBP (sterol regulatory element-binding protein) that stimulates synthesis of fatty acids in the liver, and AMPK (adenosine monophosphate kinase) that turns SREBP on and off.

They found that second-hand smoke exposure inhibits AMPK activity, which, in turn, causes an increase in activity of SREBP.

More active SREBP results in more fatty acids getting synthesized, they say.

The result is NAFLD induced by second-hand smoke, according to the researchers.

“Our study provides compelling experimental evidence in support of tobacco smoke exposure playing a major role in NAFLD development,” said Manuela Martins-Green, a professor of cell biology, who led the study.

“Our work points to SREBP and AMPK as new molecular targets for drug therapy that can reverse NAFLD development resulting from second-hand smoke. Drugs could now be developed that stimulate AMPK activity, and thereby inhibit SREBP, leading to reduced fatty acid production in the liver,” Martins-Green added.

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

New biomarker can bring rapid relief from major depression

Washington, Sept 11 (ANI): Scientists from University of California have identified a biomarker that can help accurately predict whether a particular drug will be effective in treating major depression.

During the study, the researchers measured changes in brain-wave patterns using quantitative electroencephalography (QEEG), a non-invasive, computerized measurement that recognizes specific alterations in brain-wave activity.

These changes precede improvement in mood by many weeks and appear to serve as a biomarker that accurately predicts how effective a given medication will be.

The new non-invasive test would help predict within a week whether a particular drug will be effective.

The added benefit of the biomarker test is that it ispainless and fast – about 15 minutes – and only involves the placement of six electrodes around the forehead and on the earlobes.

The researchers recruited a total of 375 people who had been diagnosed with major depressive disorder (MDD) and prescribed the antidepressant escitalopram, commonly known as Lexapro.

Then they examined a biomarker called the antidepressant treatment response (ATR) index – a specific change in brain-wave patterns.

The study showed that the ATR predicted both response and remission with an accuracy rate of 74 percent, much higher than any other method available.

The researchers also found that they could predict whether subjects were more likely to respond to a different antidepressant, bupropion, also known as Wellbutrin XL.

“Until now, other than waiting, there has been no reliable method for predicting whether a medication would lead to a good response or remission,” said Dr. Andrew Leuchter, professor of psychiatry at the Semel Institute for Neuroscience and Human Behavior at UCLA and lead author of the study.

“And that wait can be as long as 14 weeks. So these are very exciting findings for the patient suffering from depression,” said Leuchter.

The study results appear in the journal Psychiatry Research. (ANI)

Demonstration in Shopian over death of property dealer

Shopian (J-K), Sep 10 (ANI): Hundreds of residents on Wednesday took to the streets in Shopian town, 60 km from Srinagar, after a missing local was found dead.

Frenzied locals raised anti-India slogans during the funeral procession of Mohammad Hussain Zargar, a prominent member of the local ‘Majlis-e-Mushawarat’ (council for discussion), the organisation that spearheaded protests to seek justice for the rape and murder of two Muslim women.

The body of Zargar, a 42-year-old property dealer, was discovered on Tuesday He was missing since Saturday and residents alleged he had died under mysterious circumstances.

Government offices and schools remained closed and business activity came to a standstill in the town on Wednesday after Majlis-e-Mushawarat gave a shutdown call demanding a probe into Zargar’s death.

“Nothing can be said at this time. The post-mortem report is not out, when the report is out only then we can clear about that what has happened. Let’s wait for report then we will talk about it and thereafter investigations also take place, things become clear then we will come out with a positive response on the case, well,” said Muhammad Shafi Khan, spokesman for the majlis.

Soon, robot controlled by human brain cells

London, Sept 10 (ANI): Scientists from University of Reading are working on developing a robot that would be controlled by human brain cells.

Lead researchers Kevin Warwick and Ben Whalley have already used rat brain cells to control a simple wheeled robot.

During the study, the researchers grew around 300,000 rat neurons in a nutrient broth and device producing spikes of electrical activity were connected to the output of the robot’s distance sensors.

The neurons could successfully steer the robot around a small enclosure.

Based on the findings rat models, the researchers are now working on steering the robot with the help of human brain cells.

The researchers believe that understanding how the neuron culture responds to stimulation could lead to deeper insights of neurological conditions such as epilepsy.

For instance, the way large numbers of neurons sometimes spike in unison – a phenomenon known as “bursting” – may be similar to what happens during an epileptic seizure.

The research team suggests if the behavior could be altered by changing the culture chemically, electrically or physically, it might pave way for potential therapies.

To make the system a better model of human disease, a culture of human neurons will be connected to the robot once the current work with rat cells is completed.

They will analyze the differences in the behavior of robots controlled by rat and human neurons.

“We’ll be trying to find out if the learning aspects and memory appear to be similar,” New Scientist quoted Warwick as saying. (ANI)

Forgotten memories still exist in the brain

Washington, Sept 10 (ANI): A new research by UC Irvine neuroscientists suggests that memories exist even when forgotten.

With the help of advanced brain imaging techniques, the study’s scientists discovered that a person’s brain activity while remembering an event is very similar to when it was first experienced, even if specifics can’t be recalled.

“If the details are still there, hopefully we can find a way to access them,” said Jeff Johnson, postdoctoral researcher at UCI’s Center for the Neurobiology of Learning and Memory and lead author of the study, appearing Sept. 10 in the journal Neuron.

“By understanding how this works in young, healthy adults, we can potentially gain insight into situations where our memories fail more noticeably, such as when we get older,” he said.

“It also might shed light on the fate of vivid memories of traumatic events that we may want to forget,” he added.

In collaboration with scientists at Princeton University, Johnson and colleague Michael Rugg, CNLM director, used functional magnetic resonance imaging to study the brain activity of students.

Inside an fMRI scanner, the students were shown words and asked to perform various tasks: imagine how an artist would draw the object named by the word, think about how the object is used, or pronounce the word backward in their minds. The scanner captured images of their brain activity during these exercises.

About 20 minutes later, the students viewed the words a second time and were asked to remember any details linked to them. Again, brain activity was recorded.

Utilizing a mathematical method called pattern analysis, the scientists associated the different tasks with distinct patterns of brain activity. When a student had a strong recollection of a word from a particular task, the pattern was very similar to the one generated during the task.

When recollection was weak or nonexistent, the pattern was not as prominent but still recognizable as belonging to that particular task.

“The pattern analyzer could accurately identify tasks based on the patterns generated, regardless of whether the subject remembered specific details,” Johnson said.

“This tells us the brain knew something about what had occurred, even though the subject was not aware of the information,” the expert added. (ANI)

Nicotine plays “tricks” on the brain

Washington, Sept 10 (ANI): Nicotine, the addictive component in cigarettes, “tricks” the brain into creating memory associations between environmental cues and smoking behavior, say researchers at Baylor College of Medicine.

The study has been published in the journal Neuron.

“Our brains normally make these associations between things that support our existence and environmental cues so that we conduct behaviors leading to successful lives. The brain sends a reward signal when we act in a way that contributes to our well being,” said Dr. John A. Dani, professor of neuroscience at BCM and co-author of the study.

“However, nicotine commandeers this subconscious learning process in the brain so we begin to behave as though smoking is a positive action,” the expert added.

Dani said that environmental events linked with smoking can become cues that prompt the smoking urge. Those cues could include alcohol, a meal with friends, or even the drive home from work.

To understand why the associations are so strong, Dani and Dr. Jianrong Tang, instructor of neuroscience at BCM and co-author of the report, decided to record brain activity of mice as they were exposed to nicotine, the addictive component of tobacco.

The mice were allowed to roam through an apparatus with two separate compartments. In one compartment, they received nicotine. In the other, they got a benign saline solution. Later, the researchers recorded how long the mice spent in each compartment. They also recorded brain activity within the hippocampus, an area of the brain that creates new memories.

“The brain activity change was just amazing. Compared to injections of saline, nicotine strengthened neuronal connections – sometimes up to 200 percent. This strengthening of connections underlies new memory formation,” Dani said.

Consequently, mice learned to spent more time in the compartment where the nicotine was administered compared to the one where saline was given to them.

“We found that nicotine could strengthen neuronal synaptic connections only when the so called reward centers sent a dopamine signal. That was a critical process in creating the memory associations even with bad behavior like smoking,” the expert said. (ANI)

Scientists use bacteria to make radioactive metals inert

Washington, September 9 (ANI): A team of scientists is researching the use of sulfate-reducing bacteria to convert toxic radioactive metal to inert substances, a much more economical solution.

The research is being done by Judy Wall, a biochemistry professor at the University of Missouri College of Agriculture, Food and Natural Resources.

The bacteria Wall is studying are bio-corrosives and can change the solubility of heavy metals.

They can take uranium and convert it to uraninite, a nearly insoluble substance that will sink to the bottom of a lake or stream.

Wall is looking into the bacteria’s water cleansing ability and how long the changed material would remain inert.

Wall’s research could also be beneficial to heavy metal pollution from storage tanks and industrial waste.

The bacteria are already present in more than 7,000 heavy metal contaminated sites, but they live in a specific range of oxygen and temperature, making them difficult to control.

“Our research must be done in the absence of air,” Wall said. “Obviously, none but the most committed – and stubborn – will work with them,” she added.

Even if an oxygen-tolerant strain were developed, there are still multiple factors that would make applying the bacteria challenging, and these microbes can contribute to massive iron corrosion.

“Knowledge of the way bacteria live in the environment, in microbial communities, is still in its infancy,” Wall said. “We just don’t know a lot about the communication systems among microbes,” she added.

Wall and researchers from the Lawrence Berkley National Laboratory in California are investigating the bacterium’s basic genetics and hope to determine its growth limits and activity in natural settings, including how to make its interactions with metals sustainable.

They have already identified a few genes that are critical to converting uranium. (ANI)

Brain’s face processing ability does reduce with age

Washington, September 9 (ANI): A British study suggests that the ability to identify a face, when it is shown for only a fraction of a second, reduces as people age.

Lead researcher Guillaume Rousselet, from the University of Glasgow, came to this conclusion after analysing electric activity from the brains of young and old people as they watched pictures of faces with cloud-like noise.

He said: “Very few studies have attempted to measure the effect of ageing on the time-course of visual processing in response to complex stimuli like faces. We found that, as well as a general reduction in speed in the elderly, one particular component of the response to a face, the N170, is less sensitive to faces in the elderly.”

The N170 occurs 170 milliseconds after a stimulus is presented.

The researchers revealed that it was more closely associated with the appearance of a face among the young subjects.

However, in older subjects, the researcher said that it occurred also in response to noise, perhaps implying reduced ability to differentiate faces from noise.

Revealing the findings of the study, Rousselet said: “Our data support the common belief that as we get older we get slower. Beyond this general conclusion, our research provides new tools to quantify by how much the brain slows down in the particular context of face perception. Now, we need to identify the reasons for the speed reduction and for the heterogeneity of the effects – indeed, why the brains of some older subjects seem to tick as fast as the brains of some young subjects is, at this point, a complete mystery.”

The study has been published in the journal BMC Neuroscience. (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)

Tribals attend RBI’s financial outreach camp in Tripura

Agartala, Sep. 6 (ANI): Thousands of tribal families turned out to participate in a financial outreach camp organized by the Reserve Bank of India in Pitra village of Tripura.

The camp was organised with the objective of bringing awareness among villagers about banking norms.

“Bank wants to lend for projects which would generate economic activity will lead to development of north east.

So we have to be able to work together. The state government, the banks, the non-governmental organisations, the locals, Panchayati Raj institutions and the Reserve Bank will act like a catalyst to make people come together and work together for economic development,” said Usha Thorat, deputy governor, Reserve Bank of India.

Organised on the occasion of Platinum Year celebration of Reserve Bank, the camp witnessed hundreds of villagers gathered at the stalls of different banks for opening of new bank accounts.

The villagers were also informed and familiarized with various banking facilities, security features of currency notes, exchange their soiled and mutilated currency notes, exchange currency notes for coins and also look into their complains with regards to banking facilities.

“In the village there is no banking system and this camp will be of great benefit to us. The villagers had no means of saving but now we think we can save something for our future,” Bubantala Jamatia, a villager

Under the model, post offices, cooperatives, NGOs, financial institutions, self-help groups, retired employees of state or central government may act as an agent of the banks and provide services to people. (ANI)

High earners munch frequently at work, stay healthier

Washington, Sep 5 (ANI): People who earn more money are more likely to munch on muffins or chocolate bars while working, according to researchers at University of Texas at Austin.

What’s more, such people boost their chances of staying healthy – thanks to the regular munching.

Economist Daniel Hamermesh and his colleagues used data from the American Time Use Survey from the U.S. Bureau of Labor Statistics to reach the conclusion.

And they examined how much time Americans spend eating meals each day and how much time they spend “grazing” – snacking or drinking while working, watching TV or doing some other activity.

“When their time becomes more valuable, people substitute grazing for eating, essentially switching to multi-tasking. Overall, better health is associated with more time spent eating, but especially with spreading that time over more meals per day,” said Hamermesh.

It was found that over fifty percent of all adults graze each day, with their grazing time almost equalling the time they spend eating meals.

The average American adult spends about two-and-a-half hours eating or grazing every day.

The study also revealed that men graze less but spend more time eating meals than women. Overall, men spend about three-and-a-half more minutes a day eating meals than women.

It was also found that better-educated people eat more frequently, spend more total time eating, graze more frequently and spend more total time grazing than those with less education.

Higher earners also spend more time eating individual meals, graze more frequently and spend more time during each individual grazing episode.

Those who spend more time eating have a lower body mass index (BMI), on average, and view themselves as healthier than those who spend less time eating.

The National Bureau of Economic Research released the study recently. (ANI)

Vitamin C deficiency may impair newborn babies’ mental development

Washington, Sept 3 (ANI): A new study has revealed that vitamin C deficiency may impair the mental development of newborn babies.

The study showed that guinea pigs, which lack vitamin C, have 30 per cent less hippocampal neurones and significantly worse spatial memory.

According to lead researcher Jens Lykkesfeldt, like guinea pigs, human beings are dependent on getting vitamin C through their diet.

He speculates that vitamin C deficiency in pregnant and breast-feeding women may also lead to impaired development in foetuses and new-born babies.

This vitamin seems quite important to brain activity.

Tests have shown that mouse foetuses that were not able to transport vitamin C develop severe brain damage, which resembles the ones found in premature babies and which is linked to learning and cognitive disabilities later in life.

In some areas in the world, vitamin C deficiency is very common – population studies in Brazil and Mexico have shown that 30 to 40 per cent of the pregnant women have too low levels of vitamin C, and the low level is also found in their foetuses and new-born babies.

“We may thus be witnessing that children get learning disabilities because they have not gotten enough vitamin C in their early life,” said Lykkesfeldt, from Faculty of Life Sciences at University of Copenhagen.

“This is unbearable when it would be so easy to prevent this deficiency by giving a vitamin supplement to high-risk pregnant women and new mothers,” Lykkesfeldt added.

The researchers are currently studying how early in pregnancy vitamin C deficiency affects the embryonic development of guinea pigs and whether the damage may be reversed after birth.

The study appears in American Journal of Clinical Nutrition. (ANI)

Indian-origin scientists find novel therapeutic target for autoimmune diseases

London, Sept 2 (ANI): A research team led by Indian-origin scientists from University of Michigan have discovered a new mechanism that would help in future therapies for conditions ranging from autoimmune diseases to organ transplants to cancer.

U-M biochemistry professor Ruma Banerjee and her colleagues have identified a mechanism that keeps a check on aggressive immune cells that can attack the body’s own cells.

They found that immune system’s regulatory T cells influence aggressive immune cells by regulating the chemical environment between cells.

“Now we know that the redox environment outside the cell is a very important dynamic. It regulates cell function,” Nature quoted Banerjee as saying.

The processes known as redox chemistry are fundamental to the way cells derive and consume energy.

She said that regulatory T cells appear to alter the chemical environment around their aggressive cousins, known as autoreactive T cells, which either curb them or cause them to proliferate.

This mechanism is likely to be involved in inflammatory bowel disease (IBD) and ulcerative colitis.

The study conducted over live mouse immune cells showed that important redox communication occurs between dendritic cells, which are the first immune cells to detect a foreign agent, and autoreactive T cells.

Dr Sanjay Garg, a research investigator in the U-M Department of Biological Chemistry, said that the dendritic cells alter the chemical environment outside cells in a way that promotes activation of the T cells.

But then T regulatory cells “intervene in the redox chatter” and suppress that effect.

Banerjee insists that she needs to conduct more study to fully understand the process before they can use their insights to block or encourage T regulatory cell activity in animal studies of IBD or another autoimmune disease.

The study appears in Nature Chemical Biology. (ANI)
