Reviewed by James Ives, M.Psych. (Editor)Mar 12 2019A team from the Department of Psychological Medicine and Department of Biochemistry at the Yong Loo Lin School of Medicine at the National University of Singapore (NUS) has found that seniors who consume more than two standard portions of mushrooms weekly may have 50 per cent reduced odds of having mild cognitive impairment (MCI).A portion was defined as three quarters of a cup of cooked mushrooms with an average weight of around 150 grams. Two portions would be equivalent to approximately half a plate. While the portion sizes act as a guideline, it was shown that even one small portion of mushrooms a week may still be beneficial to reduce chances of MCI.”This correlation is surprising and encouraging. It seems that a commonly available single ingredient could have a dramatic effect on cognitive decline,” said Assistant Professor Lei Feng, who is from the NUS Department of Psychological Medicine, and the lead author of this work.The six-year study, which was conducted from 2011 to 2017, collected data from more than 600 Chinese seniors over the age of 60 living in Singapore. The research was carried out with support from the Life Sciences Institute and the Mind Science Centre at NUS, as well as the Singapore Ministry of Health’s National Medical Research Council. The results were published online in the Journal of Alzheimer’s Disease on 12 March 2019.Determining MCI in seniorsMCI is typically viewed as the stage between the cognitive decline of normal ageing and the more serious decline of dementia. Seniors afflicted with MCI often display some form of memory loss or forgetfulness and may also show deficit on other cognitive function such as language, attention and visuospatial abilities. However, the changes can be subtle, as they do not experience disabling cognitive deficits that affect everyday life activities, which is characteristic of Alzheimer’s and other forms of dementia.”People with MCI are still able to carry out their normal daily activities. So, what we had to determine in this study is whether these seniors had poorer performance on standard neuropsychologist tests than other people of the same age and education background,” explained Asst Prof Feng. “Neuropsychological tests are specifically designed tasks that can measure various aspects of a person’s cognitive abilities. In fact, some of the tests we used in this study are adopted from commonly used IQ test battery, the Wechsler Adult Intelligence Scale (WAIS).”As such, the researchers conducted extensive interviews and tests with the senior citizens to determine an accurate diagnosis. “The interview takes into account demographic information, medical history, psychological factors, and dietary habits. A nurse will measure blood pressure, weight, height, handgrip, and walking speed. They will also do a simple screen test on cognition, depression, anxiety,” said Asst Prof Feng.Related StoriesResearchers discover new therapeutic target for treatment of Alzheimer’s diseasePosterior parietal cortex plays crucial role in making decisions, research showsStudy provides new insight into longitudinal decline in brain network integrity associated with agingAfter this, a two-hour standard neuropsychological assessment was performed, along with a dementia rating. The overall results of these tests were discussed in depth with expert psychiatrists involved in the study to get a diagnostic consensus.Mushrooms and cognitive impairment Six commonly consumed mushrooms in Singapore were referenced in the study. They were golden, oyster, shiitake and white button mushrooms, as well as dried and canned mushrooms. However, it is likely that other mushrooms not referenced would also have beneficial effects.The researchers believe the reason for the reduced prevalence of MCI in mushroom eaters may be down to a specific compound found in almost all varieties. “We’re very interested in a compound called ergothioneine (ET),” said Dr Irwin Cheah, Senior Research Fellow at the NUS Department of Biochemistry. “ET is a unique antioxidant and anti-inflammatory which humans are unable to synthesise on their own. But it can be obtained from dietary sources, one of the main ones being mushrooms.”An earlier study by the team on elderly Singaporeans revealed that plasma levels of ET in participants with MCI were significantly lower than age-matched healthy individuals. The work, which was published in the journal Biochemical and Biophysical Research Communications in 2016, led to the belief that a deficiency in ET may be a risk factor for neurodegeneration, and increasing ET intake through mushroom consumption might possibly promote cognitive health.Other compounds contained within mushrooms may also be advantageous for decreasing the risk of cognitive decline. Certain hericenones, erinacines, scabronines and dictyophorines may promote the synthesis of nerve growth factors. Bioactive compounds in mushrooms may also protect the brain from neurodegeneration by inhibiting production of beta amyloid and phosphorylated tau, and acetylcholinesterase.Next stepsThe potential next stage of research for the team is to perform a randomised controlled trial with the pure compound of ET and other plant-based ingredients, such as L-theanine and catechins from tea leaves, to determine the efficacy of such phytonutrients in delaying cognitive decline. Such interventional studies will lead to more robust conclusion on causal relationship. In addition, Asst Prof Feng and his team also hope to identify other dietary factors that could be associated with healthy brain ageing and reduced risk of age-related conditions in the future.

The ability to deal with children’s psycho-emotional pain without inflicting additional painful experiences on them is one of the biggest challenges for caregivers and therapeutic residential care.”Authors Reviewed by Alina Shrourou, B.Sc. (Editor)May 23 2019A model of care for children’s residential agencies takes children’s emotional pain into account and emphasizes the bond between the children and their caregivers.The model was developed over nearly 15 years by the Residential Child Care Project at Cornell University. In the four-year study at 13 facilities, the Children and Residential Experiences (CARE) model reduced behavioral incidents and improved their relationships with caregivers. Related StoriesNew computational model explores daily pain sensitivity rhythmsStudy shows potential culprit behind LupusCreating a physical and genetic map of Cannabis sativaCo-authors Martha Holden, project director of the Residential Child Care Project, and Deborah Sellers, the project’s director of research, said most children and young people in residential programs have had traumatic experiences such as severe loss, neglect, rejection and abuse. Unfortunately, many agencies lack a comprehensive vision of how to help the children change and grow.To develop the CARE model, the team explored existing studies about the effects of trauma on children and strategies that have been proven effective in dealing with it. CARE orients agency practices around six core principles to produce programming that is: based on relationships between children and caregivers, informed by the trauma children have likely endured, targeted at each child’s developmental stage and needs, family oriented, focused on allowing children to develop their own competence, and open to adapting their environments to support the children’s process.In the four-year study of the CARE model, 13 agencies in North Carolina showed decreases of 3 to 5 percent per month in incidents of aggression toward staff, property destruction and running away. Children’s perceptions of the quality of their relationships with caregivers, according to surveys, improved by 8 to 14 percent.Source:Cornell UniversityJournal reference:Holden,M.J & Deborah Sellers (2019) An Evidence-Based Program Model for Facilitating Therapeutic Responses to Pain-Based Behavior in Residential Care.

Common warning signs include snoring, choking or gasping during sleep. Untreated sleep apnea can cause excessive daytime sleepiness, fatigue, and impairments in cognitive functioning.This analysis of data from the ongoing, prospective Assessing Daily Activity Patterns through occupational Transitions (ADAPT) study involved 261 participants with an average age of 41 years; 58% were women. Seventy-three percent received hourly wages rather than a salary, and about 45% of participants had a history of multiple job losses. Breathing during sleep was evaluated with a home sleep apnea test, which revealed that 42% percent had at least mild sleep apnea.After a propensity score analysis, 39 matched pairs (78 participants) remained for the logistic regression model. Results were controlled for potential confounders such as age, sex, race, and job payment type.The authors noted that one limitation of the study was the inability to include body mass index in the analysis.The research abstract was published recently in an online supplement of the journal Sleep and was presented Sunday, June 9, in San Antonio at SLEEP 2019, the 33rd annual meeting of the Associated Professional Sleep Societies LLC (APSS), which is a joint venture of the American Academy of Sleep Medicine and the Sleep Research Society.Source:American Academy of Sleep MedicineJournal reference:Haynes, P. et al.

U.S. companies are barred from selling technology to ZTE for seven years.The penalty comes as tensions mount between Beijing and President Donald Trump over technology policy, though the case dates to before Trump took office in January 2017.ZTE pleaded guilty in March 2017 and agreed to pay a $1.19 billion penalty for having shipped equipment to Iran and North Korea in violation of U.S. regulations. The company promised to discipline employees involved in the scheme, but the U.S. Commerce Department said last week that they were paid bonuses instead.The company said Sunday in a statement on the Hong Kong Stock Exchange that since 2016, it has “learnt from its past experiences on export control compliance” and “attaches significant importance” to the work.It described steps taken that include the setting up of a committee on compliance led directly by the chief executive officer and a team of experts as well as training for employees.”The Company has taken and is taking steps to comply with the denial order,” the statement said, referring to the ban issued by the Commerce Department. “The Company is making active communications with relevant parties and seeking a solution.”The sanctions could handicap ZTE’s global business selling smartphones that use Google Inc.’s Android system and network gear for phone and internet companies that incorporates U.S. chips and other technology.The sales ban also could disrupt a multibillion-dollar revenue flow to U.S. companies such as Qualcomm Inc. that supply chips, software and other technology.

Luckily, they filmed the whole thing. The divers — biologist Lizzie Daly and underwater cinematographer Dan Abbott — shared the encounter in a Facebook video posted Saturday (July 13) as part of the Wild Ocean Week campaign — a series of videos showcasing the oddities of the deep to help raise money for the United Kingdom’s Marine Conservation Society.Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65946-human-size-jellyfish-found-in-uk.html?jwsource=cl已复制直播00:0000:3500:35 Daly and Abbott were diving off the coast of Cornwall, U.K., when they saw the giant jelly emerge from the murky water. Also called the dustbin-lid jellyfish, the species is characterized by eight puffy arms capped by stinging tentacles and a large, globular head that lends the creature its unglamorous nickname. Barrel jellyfish sometimes wash up on the shore, Daly told Vice, but it’s rare for a diver to swim face-to-faceless-head with one of the massive blobs. [Marine Marvels: Spectacular Photos of Sea Creatures] While the barrel jellyfish is the largest species of jelly found in U.K. waters, it’s a mere shrimp when compared to the lion’s mane jellyfish (Cyanea capillata), the largest known species in the world. This coldwater jelly is known for its galaxy of 1,200 long, trailing tentacles, which can bring an individual creature’s total body length to up to 120 feet (36.5 meters) — which is longer than the average blue whale. This tangle of tentacles is so massive that a single lion’s mane jelly may be able to sting 50 to 100 people in just a few minutes if currents carry the jelly too close to a populated coast — a fun fact that a group of unlucky New Hampshire beachgoers learned the hard way in 2010.

Suddenly — poof — a cloud of what looks like cotton candy explodes toward the ceiling. This popular video on Twitter comes courtesy of the Malay-language account w, which shares science content. But what is going on in the video? It’s a rather dangerous version of a classic chemistry demonstration, according to Brian Hostetler, an educator at the Denver Museum of Nature & Science. The reaction is typically known as “elephant’s toothpaste,” due to its foamy appearance, and it’s commonly used in chemistry classrooms to explain catalysts, Hostetler told Live Science. [Elementary, My Dear: 8 Little-Known Elements]Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65793-cotton-candy-explosion-explained.html?jwsource=cl已复制直播00:0000:3500:35 Easy but explosive The reaction uses cheap, easy-to-access ingredients: hydrogen peroxide, dish soap, potassium iodide and food coloring. Hydrogen peroxide is key. It’s made up of two hydrogen and two oxygen molecules. The bonds between these molecules naturally break, so over time, hydrogen peroxide slowly becomes water and oxygen gas. That reaction happens faster when exposed to light, Hostetler said, which is why hydrogen peroxide is sold in brown bottles. Normally, the slow breakup (or decomposition, in chemistry terms) of hydrogen peroxide into water and oxygen is unnoticeable. But the elephant’s toothpaste experiment speeds the process with a catalyst, a chemical compound that increases the rate of a given reaction. Potassium iodide — a salt of iodine, and the dietary supplement that’s used to add iodine to table salt — provides that catalyst. “In the presence of potassium iodide, hydrogen peroxide decomposes almost immediately,” Hostetler said. The setup is simple. Hydrogen peroxide is mixed with dish soap, and food coloring is often added for a dramatic effect (which explains the cotton-candy pink in the Twitter video). The potassium iodide is added, and the iodide ion that’s part of that compound attracts the oxygen in the hydrogen peroxide, breaking the bonds and rapidly transforming the hydrogen peroxide into water and oxygen gas. The oxygen molecules then get trapped by the soap, forming bubbles, Hostetler said. In a step sometimes added to the elephant’s toothpaste demonstration, a glowing splint — a strip of wood that is hot but not burning — that is inserted into the bubbles will catch alight, sparked by the pure oxygen. Toning it down Usually, Hostetler said, the elephant’s toothpaste experiment creates an oozy concoction. So why did the Twitter version send bubbles flying toward the ceiling? That particular reaction was due to the strength of the ingredients and the shape of the containers, Hostetler said. A fairly safe version of the elephant’s toothpaste demonstration can be done at home with 3% hydrogen peroxide bought from the drugstore, with yeast as the catalyst (yeast contains the enzyme catalase, which also breaks down bonds in hydrogen peroxide). The combination will ooze and get a little warm as the reaction releases heat, but other than the need to take care not to touch the “toothpaste,” as hydrogen peroxide can be irritating to skin and eyes, this DIY version is pretty safe. The Twitter video probably shows the reaction with 30% hydrogen peroxide, or even stronger, Hostetler said. The demonstrator also uses potassium iodide that’s in powder form instead of mixed into water. And he has it poured in three batches at once into a large container with a lot of surface area, so the reaction happens across a large amount of hydrogen peroxide all at one time. That makes the scene in the video “super-duper dangerous,” Hostetler said. Thirty percent or higher hydrogen peroxide can cause chemical burns on the skin, he said, and the reaction could heat the solution by hundreds of degrees. It’s that heat and steam from the reaction that floats some of the foam skyward in the Twitter video. The bottom line, Hostetler said, is not to try the jumbo version of the demonstration at home – but feel free to press “play” again on Twitter. “It’s a cool video,” he said.

SHARE File Photo: People wade through a flooded street at Dadar in Mumbai after heavy rains in on Tuesday, July 10, 2018. – The Hindu COMMENT SHARE SHARE EMAIL In a much-needed relief to Mumbaikars, heavy rains took a break today and the suburban train services resumed functioning, officials said. The local train services were badly affected on a section of the Western Railway (WR) yesterday due to inundation of tracks. The road traffic was moving smoothly after four days of heavy rains, which had crippled life in the megacity. Trains were packed with commuters since early morning and the WR was running its services on some routes with restricted speed as the tracks were still flooded. In just 10 days, the city received 864.5 mm rain, which is nearly equal to what it gets in an entire month, the MeT department said. The local trains, considered the lifeline of Mumbai, were suspended between Nallasopara and Virar stations yesterday, causing huge inconvenience to those travelling on the busy western line.“We decided to start local train services with a cautionary note. At 6.45 am, we started services between Churchgate (in south Mumbai) and Bhayander (Thane district) stations with a restricted speed of 10 kmph,” Ravinder Bhakar, WR chief spokesperson said.“Services between Virar and Dahanu Road (in adjoining Palghar district) have also commenced,” Bhakar said, adding senior railway officials were keeping a close watch on the restoration efforts. The railway official said though the water receded on tracks near the Nallasopara station (located in adjoining Palghar district), it was still “not at a safe level” to run trains. The suburban train services between Bhayander and Virar will commence once the water level on tracks comes down further, he said. The empty stranded rakes of some long-distance trains are also being cleared one by one from tracks, he said. The Central Railway’s local train services on its main line and harbour line were running late by 5 to 10 minutes today, a CR spokesperson said. The heavy downpour yesterday had caused flooding at Vasai, Nallasopara and Virar stations, leading to cancellation of many long-distance trains. The National Disaster Response Force (NDRF), police and fire brigade personnel had rescued 2,000 passengers of Shatabdi Express and Vadodara Express. Meanwhile, Mumbai suburban guardian minister Vinod Tawde will be returning to the city from Nagpur, where he was attending the Legislative Assembly session to review the situation in the megacity following heavy rains. The minister is expected to hold important meetings with senior officials of the city civic body and police, and discuss the arrangements being made to tackle the monsoon menace, a source said. Since the onset of monsoon, Mumbai has so far received almost 60 per cent of its required annual rainfall, the MeT said. The weather department has said heavy to very heavy rainfall is likely to continue in the city and its neighbouring areas till Saturday. The Brihanmumbai Municipal Corporation’s disaster management cell also said that intermittent rain with heavy to very heavy showers is likely over the city and suburbs in the next 24 hours.

The facility needed about 60-70 tonnes of soil.ISITE’s parent, the U.R. Rao Satellite Centre, or URSC (it was called the ISRO Satellite Centre or ISAC at the time) did buy a small amount of simulated lunar soil from the U.S., but soon decided to find its own solution at a lower cost.M. Annadurai, who as URSC Director oversaw activities related to the Chandrayaan-2 spacecraft until he retired in August 2018, recounts that geologists of various national agencies had found that a few sites near Salem in Tamil Nadu had the ‘anorthosite’ rock that somewhat matches lunar soil in composition and features. The URSC’s lunar soil simulation studies team zeroed in on Sithampoondi and Kunnamalai villages for the soil.It turned out to be a ₹25 crore project: experts from the National Institute of Technology in Tiruchi, Periyar University in Salem, and the Indian Institute of Science, Bengaluru, joined in, working without any fee.Professional crushers broke down the rocks and soil to the micro grain sizes sought by the ISRO-led team. Transporters moved the tonnes of this ‘lunar earth’ to ISITE, all free of charge, Dr. Annadurai recalls.These challenges were not there when he led the first lunar orbiting-only mission, Chandrayaan-1, as its project director.At the LTTF, the team spread the soil trucked in from Salem up to a height of about 2 metres. Studios were hired to illuminate the facility exactly as sunlight would play on the lunar terrain.On the Moon, the metre-long rover, weighing 27 kg, must move for about 500 metres during its expected life of 14 Earth days (one lunar day). Rover tests began as early as in 2015. The ISRO team had to reckon with the weak lunar gravity, about 16.5% of Earth’s. The rover’s weight was artificially reduced using helium balloons.Previous missions by other countries have suggested that the southern part of the Moon is mineral rich with the promise of water, which was first confirmed by the Chandrayaan-1 mission.Lunar south poleISRO Chairman K. Sivan recently said the Indian lander Vikram would be the first ever spacecraft to land at the lunar south pole.It has two site options, the craters Manzinus-C and Simpelius-N.The sites were picked after scouring through a few thousand lunar images from Chandrayaan-1 and other missions.For testing the lander, ISRO had a large test bed created at its new R&D campus at the Challakere Science City, some 400 km from Bengaluru. Vikram’s set of sensors, called the Hazard Detection and Avoidance (HDA) system, is a critical part of the mission.In the actual descent to the Moon, the lander hovers for a few seconds over a site and the sensors must assess whether the spot is flat enough for the lander’s legs: whether it has rocks that might topple the lander, and whether the lander can be steady to release the rover within it. If the spot is not safe, it must quickly rise and shift to a neighbouring spot and again assess if it is suitable to land on, all in seconds.Sometime in 2016, the URSC created several artificial ‘lunar’ craters at the Challakere site. Late that year the team put a test bed of lander sensors in a small ISRO plane and flew it over the craters to see if the sensors could read the terrain and find the right landing spot.According to Dr. Annadurai, the success of the landing depends on the sensors’ correctly guiding the lander to a safe site; and the fuel in the lander lasting for duration of the whole exercise.Other tests were conducted to clear the working of the lander’s propulsion system, its actuator and legs, and the rover’s movement.In a joint paper presented at the International Academy of Astronautics symposium in June 2017, Dr. Annadurai and his co-authors wrote: “One of the key elements essential for safe landing is the Hazard Detection and Avoidance (HDA) system. [It] comprises of several sensors… [which] provide information like lander’s horizontal velocity, vertical velocity, height above moon’s surface, relative position of the lander with respect to moon’s surface, and hazard/safe zone around the landing site.“The HDA system processes the inputs from various sensors, compares the data collected with the information already stored in the lander and provides the required inputs to the navigation and guidance system in real time to correct the trajectory at the end of rough braking to enable a safe and soft landing.” Printable version | Jul 13, 2019 8:09:54 PM | https://www.thehindu.com/news/national/isros-lunar-touchdown-has-dry-run-on-soil-fetched-from-tamil-nadu/article28416365.ece July 13, 2019 16:09 IST Chandrayaan-2 will carry 14 Indian payloads Updated: Scaled down test for safe landing of Chandrayaan-2 lander You are reading Comments will be moderated by The Hindu editorial team.

But where on earth did the Chandrayaan-2 mission’s lander and rover, which will head for the moon on July 15, check out their legs and wheels?More than a decade ago, even as the Chandrayaan-1 orbiter mission of 2008 was being readied, the Indian Space Research Organisation (ISRO) created a proto-Lunar Terrain Test Facility (LTTF) at its advanced satellite testing unit, ISITE, in Bengaluru. This, it did, by modifying a balloon research lab, about 30-40 m high, long and wide.At the time, ISRO was grappling with the task of indigenously executing the cryogenic stage for its GSLV MkII rocket. Any thought of sending a moon lander was a distant dream of low priority. Equipping the LTTF and making it look and feel like being on the moon was the first challenge.

July 12, 2019 01:09 IST 104 Speaker of the U.S. House of Representatives Nancy Pelosi has said the U.S. Congress was, and continues to be, concerned about the treatment of Muslims in India. Ms. Pelosi’s comments came during a conversation with Chairman of the U.S.-India Strategic Partnership Forum (USISPF) John Chambers at a Forum event in Washington DC.“We were proud to welcome him [Prime Minister Modi] …to a joint session of Congress [in 2016]. We had some concerns about the treatment of Muslims in India — I have to mention it — then and now,” Ms. Pelosi said at the conclusion of a talk, parts of which focused on her domestic agenda for the US and some of which discussed the India US relationship. During the India segment of her speech Ms. Pelosi praised the diaspora and Mr. Modi.Ms. Pelosi, however, also praised Mr. Modi’s oratorical skills, calling a speech he gave during her visit to India with former U.S. President Barack Obama, “one of the most fantastic speeches” she had ever heard.Ms. Pelosi dwelt on the values that anchored ties between India and the U.S., speaking of Mahatma Gandhi’s influence on the civil rights leader Martin Luther King Jr.and also called satyagraha “the spiritual gift that India has given to the United States” and said it was one of the strong ties, in terms of values, that connected the two countries.”I became completely worshipping at the shrine of Mahatma Gandhi,” Ms Pelosi said, after she read a book about Gandhiji as a child . As per Ms Pelosi’s account, a nun at her Catholic school had said to Ms . Pelosi , “Who do you think you are? Mahatma Gandhi? ” when she went to school wearing a hat. Ms Pelosi had not heard of Gandhiji at the time and started reading up on him at her school library.

Satyajeet Kumar New DelhiJuly 13, 2019UPDATED: July 13, 2019 08:36 IST Photo for representationIt is rare in life that we get to see people who are larger than life, making sacrifices for the greater good.One such person who has come into the limelight is Padma Shri awardee Simon Oran. His story is somewhat similar to Dasrath Manjhi of Bihar.Dasrath Manjhi is the man on whose life the film Manjhi: The Mountain Man starring Nawasuddin Siddiqui was based.While the nation lauded Manjhi’s efforts to carve a road out of a mountain and came to be known as the “mountain man”, most people are unaware of Simon Oran.Simon Oran managed to build canals and constructed three dams by drilling through mountains in Bero region of Jharkhand. His efforts earned him the name “waterman”.However, though his actions have benefitted the larger community, he himself is weighed down by poverty.For his contribution to environmental protection, water conservation and rain water harvesting, Simon Oran was felicitated with the Padma Shri by the then President Pranab Mukherjee.However, his days in glory were short-lived.The man, who dared to brave mountains, is proud of his medal and certificate but has been living a life of hardships.Simon Oran has always stood up for social causes but the other side of his life has a different story.Oran lives in a thatched house, the roof of which leaks during the monsoon. However, he does not have a BPL card.He is also under debt. He had taken a loan to dig a pond.Despite his financial troubles, Oran holds his head high with pride and does not ask for help from the government or any other agency.He says that villagers have been making efforts since 1961 to preserve water and not let it flow away.The entire area where he lives is dependent on agriculture which requires a huge amount of water. Oran was able to mobilise the people of many villages to contribute in the water-saving campaign.The collective efforts eventually paid off and a canal was built by carving mountains which led to the construction of three dams to fight the water woes. Now, the situation is under control and all one sees are the lush green fields.The people still conserve the forest by taking turns to guard it. Simon Oran’s wife stays with him but she looks tired, having battled poverty all along. Her face talks about the miseries of the life they lead in financial scarcity.Simon Oran is the parha raja which means the chief of 51 villages, according to the tribal institutional provision which is also recognised by the state government. Oran commands a great respect and easily motivates people towards his cause. Irony is such that while he is known for his efforts in social causes, Oran himself struggles on the personal front.Also read: Headless bodies of 2 children found in Jharkhand village, mentally unstable man heldALSO WATCH| Blast from the past: When dosa king P Rajagopal was convicted of murderFor the latest World Cup news, live scores and fixtures for World Cup 2019, log on to indiatoday.in/sports.
