first_imgPanaji: The Goa State AIDS Control Society (GSACS) will approach the National Aids Control Organisation (NACO) under the Union Health Ministry seeking permission and funds to conduct a baseline survey of drug addicts to control HIV/AIDS.Dr. Jose D’Sa, project director of GSACS, told The Hindu on Friday that this decision was taken at a meeting of the executive committee of the society on Thursday after some doctors said they get patients (drug addicts) not only from the State’s vulnerable coastline but even from the hinterland.He said it is time the society assesses the number of drug addicts in the State to take up a programme of injecting drug addicts to control HIV/AIDSDr. D’Sa said that considering the present scenario on HIV/AIDS in Goa there has been a decline in the number of patients in recent years, which is a good trend.last_img read more

first_imgA day after a potato farmer allegedly committed suicide after suffering heavy losses, Chief Minister Mamata Banerjee on Tuesday said her government will purchase 28,000 tonnes of potatoes, required for Anganwadi centres and midday meal programme, directly from farmers. Her announcement comes at a time when potato farmers across the State are facing a severe crisis — at least two of them have committed suicide — due to the sharp drop in prices following this years’ bumper crop.Krishak Dibas“We have decided to buy 28,000 tonnes of potatoes directly from the farmers which we need every month for the Anganwadi centres and the midday meal programme. The government will buy potatoes at ₹4.60 per kg,” she said. Ms. Banerjee was speaking at a government programme on Krishak Dibas (Farmers’ Day) observed by the Trinamool Congress government on March 14 to pay tribute to those who died during the anti-land acquisition movements at Singur in Hooghly district and Nandigram in Purba Medinipur district. As per the projected estimates of the State government, the number of schools (up to Class VIII) to be covered under the midday meal scheme is 83,673 and the number of students is about 1 crore. According to potato merchants, this is the first time that the TMC government is directly purchasing potatoes from farmers.The development comes a day after a potato farmer allegedly committed suicide due to losses in farming in the Anandapur area of Paschim Medinipur district’s Keshpur block. According to his family, Swapan Hajra (45) committed suicide after sustaining “heavy losses” in potato farming. ‘Heavy debt’“He incurred a large debt for cultivating potatoes in four bighas (1.60 acres) of land,” Mr. Hajra’s son Indrajit told journalists.The Opposition, however, is sceptical whether the move will be beneficial for the potato farmers. “This is nothing but a face saving move. If the TMC government is really bothered about the farmers they would have purchased potato from them at a much higher rate,” said CPI-M district secretary of Paschim Medinipur Tarun Roy.last_img read more

first_imgThe Uttar Pradesh police have arrested 20 people on charges of murder and rioting after communal violence rocked Naseerpur village in Muzaffarnagar on Monday. One person was killed and over a dozen were injured in the violence that was triggered by a petty fight over overflowing water from a sewage line. The Naseerpur violence is the second such incident in less than a week in the district. On Saturday, hundreds of agitated villagers of Sherpur clashed with the police and burnt their vehicles after rumours of cow slaughter spread in the area.Twenty-two-year-old Akash died of a gun shot injury in the Naseerpur violence. Three hundred people have been booked. According to the police, Iqbal was on his way to the local mosque on Monday when he got into an argument with one Brijpal over an over flowing drain. The issue was sorted out in the afternoon at a meeting of the village elders, who persuaded them to arrive at a compromise. But by the evening, the issue flared up again and led to a violent clash in which people attacked each other with firearms and stones. Brijpal and his son Akash were injured in the firing. Akash succumbed to his injuries on the way to the hospital.Village head arrestedThe police arrested the Naseerpur village head, Sabir on Thursday after he was named in an FIR filed by Brijpal. Sabir, however, told The Hindu that he had nothing to do with the clash. “I had organised a panchayat, where the village elders brought about a compromise between Iqbal and Brijpal. But the same evening, they started fighting once again,” he said. Superintendent of Police (city) Muzaffrnafar Rakesh Kumar Singh told The Hindu that paramilitary forces and Provincial Armed Constabulary had been deployed in the village and the situation was “under control.” Many fledMany Muslim families have reportedly fled the area fearing retaliation after an angry mob, despite the police deployment, set the house of a person accused of firing at Akash. BJP leaders, including Union Minister and the local MP Sanjeev Baliyan, met the family of Akash on Wednesday. They also talked on the phone to Chief Minister Adityanath, who they said had agreed to ensure that the victim’s family was granted ₹20 lakh in compensation and a government job for one of its members.last_img read more

first_imgBihar Chief Minister Nitish Kumar on Monday said that the issue of his party JD(U) joining the Union government was a “media speculation”.“We neither considered the issue nor we had any desire or expectation (about joining the Union government). The issue was speculated in the media. It was baseless and unfounded,” the JD(U) president told reporters here.Prime Minister Narendra Modi had on Sunday carried out a reshuffle of his Council of Ministers. He had inducted nine BJP leaders into the government.Speculation was rife that two MPs of the JD(U), which recently joined the NDA after severing ties with the RJD and the Congress in Bihar, might be given ministerial berths at the Centre.“Your (media) speculation has been proved wrong and you should close the chapter,” Mr. Kumar said..He said he works in a transparent manner and the media can straightaway ask him about the party’s affairs as he is ready to answer such questions.The Chief Minister had on Saturday also said no talks between his party and the BJP took place on the issue of the JD(U) becoming part of the Union government.To a question on when the party would take action against rebel leader Sharad Yadav, Kumar said, “We will let you know at an appropriate time. But till then, don’t speculate.”last_img read more

first_imgSenior Congress leader and former Union Minister Priya Ranjan Dasmunsi passed away on Monday at a private hospital in New Delhi. He was 72.Mr. Dasmunsi suffered a massive stroke and paralysis in October 2008 and slipped to comatose. He was treated in Apollo Hospital in New Delhi since 2009. “He breathed his last at 12:10 pm. He developed chest infection last month and it worsened his condition,” sources in the hospital said.“I just received the news of sad demise of former Union Minister, former West Bengal Pradesh Congress Committee President and our beloved leader Priya Ranjan Dasmunsi,” State Congress president Adhir Ranjan Chowdhury stated in a letter to Congress president Sonia Gandhi.”Our deepest condolences on the passing of respected Priya Ranjan Dasmunsi, our veteran Congress leader and former union minister.

first_imgThe Madhya Pradesh government has given an “in principle” nod to translocate three pairs of tigers to Odisha’s Satkosia Tiger Reserve (STR), an official said on Monday. The six tigers are likely to be translocated by March-end, as the All India Tiger Estimation (AITE) 2018 is currently under way in the State. According to the officer, the in-principle approval came after Chief Minister Shivraj Singh Chouhan agreed to the Odisha government’s request for translocation of the big cats. Principal Chief Conservator of Forest (PCCF), Wild Life, Jitendra Agrawal said the STR is left with only one pair of tigers, who have passed their average age. In the last few days, only one of the big cats was captured in cameras in the STR, he said. Acting on a letter written by the Odisha government, the National Tiger Conservation Authority’s (NTCA’s) technical committee at a recent meeting approved shifting of the tigers. Later, the M.P. government also decided to allow the translocation, which would help in increasing the number of the striped cats in the STR.Mr. Agrawal said the genetic make-up of tigers in STR was similar to that of the Bandhavgarh and Kanha Tiger Reserve in M.P. There has been evidences of a tiger corridor between M.P. and Odisha, he said. “It is expected that the tigers of M.P. would easily adopt new climate of Odisha,” he said. Mr. Agrawal said the officials and employees would be trained in the tiger release protocol.last_img read more

first_imgThree cities in Maharashtra — Pune, Navi Mumbai and Greater Mumbai — top the first Ease of Living Index brought out by the Union Ministry of Housing and Urban Affairs. The national capital, New Delhi, is ranked 65 among 111 cities, while Chennai is in 14th place. Kolkata did not participate in the survey.A city’s ranking reflects its ability to provide data, as well as its actual performance on four different parameters — institutions or governance, social indicators, economic indicators and physical infrastructure. Senior Ministry officials told The Hindu that cities which were unable or unwilling to provide data received low scores.Data deficientFor example, New Delhi has a score of “zero” on indicators regarding inclusive housing and mixed land use and compactness, and a score of just 0.12 on economy and employment.This does not mean that the capital actually performs so poorly on these indicators, according to members of the consortium which carried out the survey and produced the Index for the government. Instead, it probably means that the NDMC and the three Municipal Corporations which govern the city simply failed to provide any data on those indicators.  “If Delhi is showing zero in any category, it probably means that no data was given for any indicator under that category,” a consortium member told The Hindu, explaining that urban local bodies had been required to respond to 553 questions in 15 different categories under the four parameters.Releasing the Index, Housing and Urban Development Minister Hardeep Singh Puri said the ranking marks “a shift to a data-driven approach to urban planning and management.” He said future editions of the Index may also incorporate citizen and stakeholder feedback rather than relying on government data alone.A consortium member admitted that it was a challenge to collect some of this information from data-starved urban local bodies.Complex administrationParticular complications were seen in indicators such as health —where local governments did not have access to data from private hospitals. The consortium assisted cities in plugging the data gap with regard to certain indicators.“If cities are not able to provide data, how will they be able to plan and use their resources well? The first thing they need to learn is to get their data ecosystem aligned,” pointed out a consortium member.The other cities in the top ten include Tirupati, Chandigarh, Thane, Raipur, Indore, Vijayawada and Bhopal. The three cities at the bottom of the rankings are Rampur, Kohima and Patna.last_img read more

first_imgSix Prime Ministers have visited Nagaland. But none of them, including Narendra Modi, has found as much space in the heart of the Nagas as Atal Bihari Vajpayee.It was not just because Vajpayee was the first Prime Minister to recognise the “unique history of the Nagas” and provide a development package. His choice of words at a public reception in the State capital Kohima on October 28, 2003, endeared him to the people who — because of years of separatism — had never thought highly of “Indian” leaders.His opening line in Nagamese, the State’s lingua franca, translated into: “My dear brothers and sisters, I am very happy to be in your midst on the soil of Nagaland.” “For too long, this fair land has been scarred and seared by violence … My government has been doing everything possible to stop this bloodshed, so that we can together inaugurate a new era of peace, development and prosperity in Nagaland,” he said.Abu Metha, a leader of the party Nagaland Chief Minister Neiphiu Rio belongs to, was the editor of a local daily when Mr. Vajpayee visited the State that year. He recalled how he took a split-second decision to travel by road to Kohima from Dimapur when the helicopter trip was called off because of bad weather. “This decision by the Prime Minister to come to Kohima by road and travel for close to two hours has, indeed, won the hearts of the Naga people in more ways than one.While on the bumpy road, Mr. Vajpayee passed instructions for the road to be converted into four-lane.The Isak-Muivah faction of the National Socialist Council of Nagaland also recalled the role Mr. Vajayee played in taking the Naga peace process forward. “During his leadership, the unique history and situation of the Nagas was officially recognised by the Government of India on July 11, 2002,” it said on Thursday.last_img read more

first_imgActing Vice-Chancellor of the Manipur University K. Yugindro Singh has apologised to Governor Najma Heptulla for stating that she extended “overt support” to agitators during a recent stir at the varsity, a Raj Bhavan official said on Wednesday.Prof. Singh wrote to the Officer on Special Duty/Secretary to the Governor on October 8 and apologised for his “incorrect and inappropriate” remark, he said.Prof. Singh, in a letter written to the the Union Ministry of Human Resource Development on October 3, had claimed that Ms. Heptulla questioned his taking charge as V-C of the central university and expressed her support in favour of the agitators, during a meeting on September 21. “I, hereby, humbly and respectfully tender my unconditional apology to the Governor of Manipur for incorrect and inappropriate statements made by me, including breach of protocol and propriety, related to the Governor,” Prof. Singh said in the letter. He said during the meeting the questions asked by the Governor were not fully understood by him because of “mental stress”. “I had inadvertently made incorrect and inappropriate understanding of the questions of the Governor,” he said.last_img read more

first_imgHeart-rending scenes were witnessed in Mohammadpur Bhuria village of Udham Singh Nagar district as slain CRPF jawan Virendra Singh’s three-year-old son lit his funeral pyre on Saturday.People flocked to Singh’s residence this morning to pay their last respects to the soldier who lost his life in the Pulwama terror attack on Thursday. Prominent among those who attended the funeral and gave their shoulders to Singh’s coffin were Union Minister of State for Textiles Ajay Tamta, Uttarakhand minister Yashpal Arya and Khatima MLA Pushkar Singh Dhami. CRPF jawans fired three rounds in the air to pay their last respects to the 35-year-old, the youngest son of Diwan Singh. Virendra Singh had rejoined his duties in Jammu and Kashmir only last week after a brief vacation at home for 20 days.Union minister Ajay Tamta announced a compensation of ₹25 lakh and a government job to Singh’s family. Markets in Khatima, Chakarpur and Jhankat kept their shutters down.Ex-Army men held a procession in Khatima where they raised anti-Pakistan slogans.last_img read more

first_imgA Kashmiri college student helping a friend write an article gave up after repeatedly trying to get Kolkata’s Kashmiris to speak. They refused to talk, the student said.“Even my father refused to talk about the nature of fear that has gripped us over the last week,” the student said on condition of anonymity, adding, “Please do not disclose my gender. I do not want to be the reason of trouble for my family and for Kashmiris.” The few hundred Kashmiris in Kolkata have experienced unprecedented hostility over the last week.“An absurd number of hate messages have flooded Facebook. Kashmiri women are issued rape threats, men are threatened with lynching and attacks on their families,” the student said, showing screenshots of hate messages. One of the screenshots notes that a similar “number of [a slang] Kashmiris are available in Bengal,” indicating that the Pulwama terror attack could be avenged in Kolkata.In the past one week, a prominent doctor has been threatened, a shawl seller was brutally beaten in Nadia district, another was threatened in Lalbag in Murshidabad, while other cases are reported but could not be verified. In Lalbag, both the accused and the victim, the shawl seller, were arrested.Many are surprised that Kashmiris in the city are not speaking up. “The reason is because it is a tiny group,” said Sabir Ahamed, organiser of a community-based campaign to diffuse communal tension, Know Your Neighbour. “The other factor, however, is even more distressing. As soon as a news report is published, people equipped to create trouble are digging out names, locations and even house numbers of the threatened persons, analysing data and issuing more threats. So media reports that are casually disclosing identities are not helping in any way,” Mr. Ahamed said.The student said news of attacks on Kashmiri traders in the city and “the Muslim-Kashmiri identity” was also a reason. They never expected “such behavior” in Kolkata as many have been living in Kolkata for generations.A Kashmiri housewife said she is planning to leave the city for Hyderabad, “because the politics of Bengal has some form of bloodiness in it, at least before the elections.” She said, “Many of our friends and cousins are trying to move to southern States. We have heard that there are fewer or no threats to Kashmiris in south. Perhaps women are safer in Karnataka compared to Bengal.”However, one Kashmiri, a government servant in Srinagar on a visit to Kolkata, said that he is not too keen to return to his home State before the scheduled date of departure.last_img read more

first_imgWait until next year.That’s what the National Science Foundation (NSF) has told benthic ecologist Stacy Kim, who later this month was expecting to assemble her 13-member research team in Antarctica to study its intricate food web. Although the U.S. Antarctic program that NSF runs is back in business, fears that the 16-day U.S. government shutdown would squeeze out research on the frozen continent have become reality for some scientists.The bad news for Kim came this past Friday morning, only 24 hours after her program manager and the rest of the NSF staff had returned to work. “He said my project was unsupportable because the resources won’t be available in time,” says Kim, a researcher at Moss Landing Marine Laboratories in northern California, a part of the California state universities. “So the project is being delayed until next year.”Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)Kim has an NSF grant to study how the foraging habits of the continent’s top predators—Adélie penguins and minke and killer whales—affect distribution of their prey, mainly krill and silverfish. The project is based at a field camp set up on the sea ice outside McMurdo Station, the biggest of the three U.S. Antarctic outposts. It includes a remotely operated submersible equipped with environmental sensors as well as divers. This year, her second and final field season of the 4.5-year grant, Kim had also arranged a one-time only collaboration with scientists at nearby Italian, New Zealand, and Australian bases to expand the geographic scope of her project.The research requires considerable logistical support. Researchers need snowmobiles early in the season to carry ice cores and water samples back to the station. Once the ice becomes too unstable, the ferrying is done by helicopter. Kim doesn’t know why her project was pulled out of the lineup, nor the criteria that NSF is using. But she understands that both NSF and the contractor, Lockheed Martin, are being forced to make some hard choices.“It’s a tough job to coordinate everything, and I sympathize with what they are going through,” she says. “But the fact that it happened so quickly makes me think that NSF has created some rules that it is applying without actually looking at individual projects.”Kim said the contractor, based in Denver, asked her the day after NSF announced the stations would be going on caretaker status if it would be possible to scale back her research. The contingency plan she submitted reduced the number of samples to be collected “to the minimum needed to still be able to carry out the work we had promised to do,” she says. “But the international collaborators are only available this year, for one month, so I didn’t want to eliminate them.”Although NSF has promised her that the project will be supported in the 2014 to ’15 season, Kim isn’t sure that she’ll be able to retain her team. “Some of the engineers and technicians will have to go on unemployment, because if they can’t go to Antarctica they can’t work,” she says. “I have two grad students finishing a master’s program, and a 1-year delay will be a big blow to them. My postdoc is in his last year. I’m also concerned about the future of my new Ph.D. student, because delaying her start is not good.” The rescheduling also creates a logistical nightmare. “Everybody has sublet their places,” Kim explains. “Now that they won’t be going to Antarctica for 3 months, they’re going to have to figure out where to live.”On Friday, the U.S. Antarctic Program issued a “Dear Colleague” letter to the community on its plans for rebounding from the shutdown. The letter, from Scott Borg, head of the Antarctic Sciences Section, included this description of how projects would be scheduled:“NSF decisions about priorities for restart are conditioned by factors such as continuity of long-term data sets, time-criticality of observations or studies, impacts on young or early career investigators, and international or interagency partnerships. Our deliberations have been, and will continue to be, informed by input provided by the potentially affected Principal Investigators.”*Updated, 21 October, 9:40 a.m.: This article was updated to include information on a “Dear Colleague” letter that the U.S. Antarctic Program sent to researchers on Friday, 18 October.last_img read more

first_imgSharkskin is as rough as high grain sandpaper thanks to millions of small toothlike scales called denticles. Grooves along these denticles smooth the flow of passing water, giving swimming sharks a boost and inspiring a team of researchers to produce its own sharkskin-inspired material. The team first created a detailed denticle computer model by scanning the skin of a shortfin mako shark (Isurus oxyrinchus) purchased at a local fish market. Using a 3D printer, the team studded thousands of identical 2-millimeter denticles onto both sides of a flexible foil, as pictured above. The researchers then attached their newly formed faux sharkskin to a robotic arm, allowing the material to either remain stationary in flowing water or flap fishlike through stationary water. In slow-flowing water, the denticles reduced drag on the foil by 8.7%, the researchers report online today in The Journal of Experimental Biology. The benefits were even more pronounced when the robotic arm mimicked a swimming motion, the team reports, with a 6.6% increase in swimming speed and a 5.9% reduction in energy expenditure. The researchers believe the material could one day be used in speed-boosting swimsuits, though they admit major manufacturing challenges could leave the idea dead in the water.last_img read more

first_imgOur solar system’s asteroid belt, which lies between Mars and Jupiter, may contain a few hundred thousand objects. But much farther away, in regions long presumed to be the realm of comets and other icy bodies, there could be billions of rocky orbs circling the sun, a new study suggests. Researchers used computer programs to simulate the fate of objects circling our young sun once its planetary disk was largely cleared of gas and dust. Gravitational interactions with planets over the subsequent 4.5 billion years caused some objects to crash into the sun and others to be flung out of the solar system altogether. But many of the objects were cast into exile in the Oort cloud, a spherical haze of objects that stretches far beyond Neptune and a good fraction of the way toward our nearest stellar neighbors. (The image above depicts the Oort cloud as compared with the solar system and the much nearer Kuiper belt of objects.) Of those deportees, about 4% came from within about 375 million kilometers of the sun, rendering them rock- or metal-rich bodies like asteroids rather than icy orbs like comets, the researchers report online ahead of print in the Monthly Notices of the Royal Astronomical Society. Previous observations suggest that the Oort cloud contains about 200 billion comets, the researchers note. If that’s correct, the new results suggest that those comets are accompanied by about 8 billion asteroids. If one of those objects ever fell toward Earth, it would be tougher to spot than a comet (being much darker) and more difficult to divert than the typical near-Earth asteroid (as it would be traveling much faster). Don’t fear, though: The team estimates that a planet-killing collision with such an object might happen only once every billion years or so.last_img read more
