have reduced arsenic in water By
the A.M. Costa Rica staff
The Ministerio de Salud said that a committee has been set up to address the problem of arsenic in the drinking water in some Guanacaste communities. The health agency also said that as a first step Kancham arsenic filters have been installed in some homes, as was recommended by the Pan American Health Organization. These are sand filters that can process a limited amount of water a day. The filter uses sand and pieces of metal to bind the arsenic. The ministry is working with the Instituto Nacional de Acueductos y Alcantarillados, the Presidencia and affected municipalities. The Sala IV constitutional court has taken up the efforts by residents to obtain water without arsenic. The ministry said that the second stage is to find clean sources of water. This means more drilling and at a greater depth to avoid contamination by naturally occurring arsenic. The ministry said that efforts already have reduced the presence of arsenic in the domestic water in Bagaces Centro and Cañas Centro, as well as Vergel and Jabilla de Cañas. After years of inaction, Acueductos y Alcantarillados has taken to the television channels to promise clean water to all parts of the country. Traveler alert issued over measles, rubella Special
to A.M. Costa Rica
The Pan American Health Organization, a U.N. agency, has issued an alert urging nations to strengthen their international travel advisories so that they are protected against measles and rubella prior to departure. This recommendation applies to both incoming travelers and for those traveling outbound of the region, the agency said. Due to upcoming cultural and sporting events that will be hosted by countries in the Americas, Pan American Health said it encourages nations to recommend vaccination against measles and rubella for all travelers to and from the countries of the Americas in order to reduce the risk of reintroducing these diseases that have already been eliminated in the Americas. Travelers who are not vaccinated against measles and rubella are at risk of getting these diseases when visiting countries where these viruses are circulating. Country officials should seek to ensure vaccination, with particular attention to women of childbearing age to prevent any infection caused by the rubella virus during pregnancy. The agency said that evidence of immunity to measles and rubella for travelers includes: • Written documentation of having received the measles and rubella vaccines; • Laboratory confirmation of rubella and measles immunity (a positive serologic test for the measles and rubella-specific IgG antibodies). Travelers over 6 months old who are unable to present the documents indicated should be advised to obtain vaccination for measles and rubella or preferably the measles, mumps, and rubella vaccine, said the health agency. Ideally, the vaccine should be administered at least two weeks before departure. Travelers with medical problems involving vaccination for measles and rubella are the exception to the above instructions, aid the agency. In addition, infants under 6 months old should not be vaccinated, it said. The agency said that for the duration of the trip and upon returning to their point of origin, travelers should take notice of the following symptoms: fever, rash, cough, runny nose or conjunctivitis (red eyes). If the traveler believes that they have measles or rubella, said Pan American Health, they should: remain in the place where they are lodging (hotel or home, except to go to a doctor. They should not travel nor go to any public places;and they should avoid close contact with other people for seven days following onset of rash. The agency also advised personnel in the tourism and transportation sectors to also be immunized against measles and rubella. There have been some sports events that brought many spectators from other continents. In addition, the World Cup is planned next year in Brazil. That also is the country where Pope Francis is now hosting World Youth Day which had attracted great numbers of persons form all over the world. Oldest U.S. cave art holds strong religious significance By
the A.M. Costa Rica wire services
Jan Simek, leader of the team that discovered the oldest known cave art in the United States, says he is far from finished. The 60-year-old science professor at the University of Tennessee still plans to belly crawl through caves or climb atop bluffs in the hope of finding more art in his cave-rich state. The Simek team's discovery of 6,000-year-old art in the Cumberland Plateau, a division of the Appalachian Mountains extending from southern West Virginia to northern Alabama, is featured in the June issue of Antiquity, the archeological journal published by Britain's Durham University. “Yes, we have cave art that is 6,000 years old,” Simek said. “But we don't want to say it is the oldest rock art.” Simek said there might be ancient rock art in 400 or 500 of the 9,000 caves recorded in the limestone and sandstone bedrock of Tennessee. His team has explored about 1,000 of them so far. “We are in the early stages of this, to be honest,” he said. Cave locations are kept secret because of concerns that looters could damage any archeological treasures that may be inside. By global standards, 6,000-year-old cave art is still relatively youthful. Experts say the famous Paleolithic paintings in Lascaux, France, are as old as 20,000 years. Other drawings found in Australia and southern Africa are believed to be older still. Nonetheless, archeologists and Native Americans are excited about the discoveries by Simek and his team: Alan Cressler of the U.S. Geological Survey; Nicholas P. Hermann of Mississippi State University and Sarah C. Sherwood of the University of the South in Sewanee, Tennessee. Albert Bender, a Cherokee and board adviser for the Nashville-based Native American Indian Association of Tennessee, said the discovery “shows the sophistication of Native American society in the South going back thousands and thousands of years.” Michael Moore, director and state archeologist in Tennessee's Division of Archeology, described the team's find as extremely exciting and extremely significant for the different insights into prehistoric culture. Simek said his team's main focus was on the connection of the art to religion. Some of the drawings show humans hunting or engaging in magical activities like flying. Others depict more mythological or spiritual images such as serpents and circles. “We know that these folks had recognized multiple layers of reality, and humans only occupied one of the layers in the middle,” he said. “But they interacted with and were influenced by a celestial world, an upper world that had certain creatures and spirits associated with it and an underworld that had other spirits associated with it.” Simek said this multi-tiered religious view was represented by the figures on bluffs, those in the open air, and those beneath the ground in the Cumberland Plateau. He compares the spiritual view of the artists with other religions, including Christianity. “Christ was taken to the top of the mountain, crucified, taken down, put in a cave and from there was reborn,” he said. “Those are the vertical levels of our spiritual world.” To him, the artwork and the sheer physical demands required for the painters and carvers to reach so high on the bluffs as well as so far below ground to depict their spiritual hopes and fears are proof that a sophisticated society predated people who currently call Tennessee home. “This stuff is thoughtful, insightful, profound, sacred,” said Simek, who fortunately is neither claustrophobic nor afraid of the dark. “These people have taught me a great deal about the power of the human mind.” Then he stopped and added: “It's a lot of fun.” Researchers find how brain can learn new vocabulary By
the King's College London news staff
For the first time scientists have identified how a pathway in the brain which is unique allows humans to learn new words The average adult's vocabulary consists of about 30,000 words. This ability seems unique to humans as even the closest species , chimps, manage to learn no more than 100. It has long been believed that language learning depends on the integration of hearing and repeating words but the neural mechanisms behind learning new words remained unclear. Previous studies have shown that this may be related to a pathway in the brain only found in humans and that humans can learn only words that they can articulate. Now researchers from King's College London Institute of Psychiatry, in collaboration with Bellvitge Biomedical Research Institute and the University of Barcelona, have mapped the neural pathways involved in word learning among humans. They found that the arcuate fasciculus, a collection of nerve fibers connecting auditory regions at the temporal lobe with the motor area located at the frontal lobe in the left hemisphere of the brain, allows the sound of a word to be connected to the regions responsible for its articulation. Differences in the development of these auditory-motor connections may explain differences in people's ability to learn words. The results of the study are published in the journal Proceedings of the National Academy of Sciences. Marco Catani, co-author from King's College London Institute of Psychiatry said: "Often humans take their ability to learn words for granted. This research sheds new light on the unique ability of humans to learn a language, as this pathway is not present in other species. The implications of our findings could be wide ranging – from how language is taught in schools and rehabilitation from injury, to early detection of language disorders such as dyslexia. In addition these findings could have implications for other disorders where language is affected such as autism and schizophrenia." The study involved 27 healthy volunteers. Researchers used diffusion tensor imaging to image the structure of the brain before a word learning task and functional MRI to detect the regions in the brain that were most active during the task. They found a strong relationship between the ability to remember words and the structure of arcuate fasciculus, which connects two brain areas: the territory of Wernicke, related to auditory language decoding, and Broca's area, which coordinates the movements associated with speech and the language processing. In participants able to learn words more successfully, their arcuate fasciculus facilitated faster conduction of the electrical signal. In addition the activity between the two regions was more co-ordinated in these participants. Catani concludes, "Now we understand that this is how we learn new words, our concern is that children will have less vocabulary as much of their interaction is via screen, text and email rather than using their external prosthetic memory. This research reinforces the need for us to maintain the oral tradition of talking to our children."

Some lawmakers want to ease the bite of
alcohol licenses |
|
By
the A.M. Costa Rica staff
Lawmakers from the Partido Acción Ciudadana said Tuesday that they have prepared a change in the country's alcohol law that will make the liquor licenses progressive. Right now, the license fees are the same and fixed by the municipality under the framework of the national law. The lawmakers said that they were concerned about family operations in rural areas that were facing confiscatory license fees. The lawmakers warned that some businesses might have to lay off workers or even close. Of course, these are among the same lawmakers who passed the law in the first place. Not only rural merchants are feeling the weight of the new |
fees,
depending on where the business is located. And in most cases it is the
end consumer who actually pays for the fees with higher prices. "The current license that these small businesses pay, many of them located in the countryside, are excessive because they do not correspond to the volume of sales and that impedes their continued operation," said Gustavo Arias Navarro, one of the lawmakers. Basically the new legislation would tie the license fee to sales so that the big multinational chains pay much more, said the lawmaker. The measure may not be well received in the full legislature. Part of the reason for raising the license fees was to cut down on alcohol use. |
Labor harassment bill approved by
legislative committee |
|
By
the A.M. Costa Rica staff
A legislative committee approved and sent to the full legislature Tuesday a labor harassment bill that seems to expand greatly the prohibited actions The measure would cover both public and private workplaces. Although it is supposed to be gender neutral, the summary to the bill said that it is women who as more subject to harassment than men. The bill was released by the Comisión Permanente Especial de la Mujer. The text of the measure that is on file at the legislative Web site says that labor harassment includes isolating someone, failing to assign them duties, and to speak to others in their presence without speaking to a presumed victim. Also prohibited is to keep an employee from going to a work meeting without justification. The bill sets up an arbitration system after an investigation by three persons, including one trained in workplace harassment. In determining guilt of a presumed harasser, the bill calls for circumstantial proof if there is no direct evidence. |
The law says those found guilty of
labor harassment shall be fired. A
lot of the administrative work involving a harassment claim is in the
hands of the Ministerio de Trabajo. Employers would have to set up an internal procedure so that complaints can be made The bill is the work of Mireya Zamora Alvarado, a deputy. who held an administrative post in the legislature. A summary by the committee said that this bill fills a void in existing harassment legislation. For example, there already are measure against sexual harassment. Pilar Porras, chairwoman of the committee, said that the actions of harassment include insults, forcing people to do denigrating work incompatible with their knowledge or impossible to do. The summary also said that there would be room for warnings or suspensions, even though the text says clearly that the penalty is firing. However, public officials, including local mayors, could not be fired, They would only be admonished. |

Scientists use an airborne system to map carbon densities in
Panamá |
|
By
the Stanford University news staff
A team of researchers has for the first time mapped the above ground carbon density of an entire country in high fidelity. They integrated field data with satellite imagery and high-resolution airborne light detection and ranging data to map the vegetation and to quantify carbon stocks throughout the Republic of Panama. The results are the first maps that report carbon stocks locally in areas as small as a hectare (2.5 acres) and yet cover millions of hectares in a short time. The system has the lowest demonstrated uncertainty of any carbon-counting approach yet — a carbon estimation uncertainty of about 10 percent in each hectare overflown with the detection instruments as compared to field-based estimates. Importantly, it can be used across a wide range of vegetation types worldwide. The new system, described in Carbon Balance and Management, will greatly boost conservation and efforts to mitigate climate change through carbon sequestration. It will also promote understanding of how carbon storage can be used to assess other fundamental ecosystem characteristics such as hydrology, habitat quality, and biodiversity. The approach provides much-needed technical support for carbon-based economic activities such as the U. N. Reducing Emissions from Deforestation and Forest Degradation program in developing countries. Panama has complex landscapes, with variable topography and diverse ecosystems, ranging from grasslands and mangroves to shrub lands and dense forests. As a result, Panama is an ideal laboratory to develop and test a method for quantifying aboveground carbon. Lead author Greg Asner commented: “Three things make this national-scale study unique. First, Panama is an outstanding place for testing carbon mapping approaches due in part to the long-term forest studies that have been undertaken by our partners at the Smithsonian Tropical Research Institute. Second, we have applied the very latest techniques using high-performance instrumentation, resulting in demonstrably high accuracy at fine spatial resolution. And third the partnership permitted us to estimate our errors in a novel way, and we did so over every point on Panamanian soil.” In addition to Carnegie and Smithsonian researchers, scientists from McGill University and the University of California at Berkeley combined measurement methods — an extensive and essential network of |

ground-based plot sampling, satellite imagery, and air measurements from the Carnegie Airborne Observatory — to achieve the unprecedented accuracy. The light detection and ranging system uses reflected laser light to image vegetation canopy structure in 3-D. The scientists calibrated the measurements, taken at one-meter resolution throughout nearly one million acres (390,000 hectares), to the carbon density in 228 regional field plots, established and sampled by the collaborating scientists. They used 91 other plots to validate the aboveground carbon density estimates. "Rarely has such a large number of field plots been available to validate LiDAR calibration independently,” remarked Asner. “Our collaboration with STRI and its partners was vital to assess the accuracy of what we achieved from the air.” Traditional carbon monitoring has relied upon on-the-ground sampling of field plots, but this approach usually represents just small areas of land and is time-consuming. “There has been growing interest in using satellite imagery to cover larger areas, but it is low resolution both spatially and in terms of the structural information about the vegetation,” said Carnegie author Joseph Mascaro. “In some parts of Panamá, different global methods disagree by more than 100 percent at square-kilometer scale.” That’s where the airborne light detection and ranging comes in. It directly probes the ecosystem’s physical structure, which Carnegie scientists have repeatedly proven to be tightly linked to tropical carbon stocks. These measurements are the bedrock for mapping and estimating the amount of carbon locked up in plants from dense forests to shrub lands. |

Pope resumes
hectic schedule
today with visit to shrine By
the A.M. Costa Rica staff
Pope Francis resumes a hectic schedule in Brazil today with a visit to a shrine in Sao Paulo state to venerate the Roman Catholic country's patroness. Nearly 2,000 police are set to provide security for the pontiff as he prays at the shrine of the Virgin of Aparecida along with about 200,000 faithful. As the pope rested Tuesday, there was widespread finger-pointing in Brazilian media over security lapses that exposed the 76-year-old Francis to mobs of wellwishers who greeted him Monday on his arrival in Rio de Janeiro. Analysts acknowledged serious security lapses, but they said the wishes of the pope to be out among the public made it difficult to ensure full protection. Throughout the ordeal, the pope himself appeared upbeat and kept his car window open to greet the crowds that swarmed his motorcade. The Rio visit and the return to Francis' home continent was planned to coincide with Thursday's international celebration of World Youth Day. More than one million young Catholics are expected to participate, and hundreds of thousands of young people are already in the city, awaiting the opportunity to greet the new pope. In addition to his visit to the Sao Paulo shrine, the pontiff also will meet with young inmates at a Rio prison, visit shantytowns largely cleared of drug gangs earlier this year, and inaugurate a Rio hospital wing for the treatment of drug addicts. Francis' visit, his first foreign trip since becoming pope in March, comes at a time of social upheaval in Brazil that began last month with protests against a bus fare increase in Sao Paulo. Those demonstrations quickly grew into massive street protests against government expenditures for hosting the 2014 Word Cup soccer tournament, and spread to include protests against official corruption. France facings more woe from its Muslim minority By the A.M. Costa Rica wire
services
As temperatures soar in France, tensions are also on the rise over Islam, immigration, violence and the state's response to long-simmering tensions in the country's low-income suburbs. It all started with weekend clashes outside the French capital. Just as French government ministers begin packing their holiday suitcases, violence erupting in the Paris suburb of Trappes suggests they may not be in for a calm summer. Dozens of people assaulted the Trappes police station this past weekend, throwing fireworks and setting trash cans on fire. The incidents apparently took place after police arrested a man for assaulting them, after they detained his wife for wearing the face-covering veil in public — a practice that is banned in France. The chain of events sparks memories of previous unrest, first in 2005, when youth riots swept across the country, mostly in immigrant-heavy neighborhoods. In 2010, a new French law banning the face veil also triggered debate and anger. What's different today, says French sociologist Michel Wieviorka, is the connection between the two issues. Wieviorka is the author of "Evil," a book exploring terrorism, violence and racism. "There is something which is really new. It is the fact that suddenly two issues that in the recent past were distinct became one and only issue. That is to say, on the one hand, you have many people living in these kinds of poor suburbs that are facing social inequalities, exclusions, racism, police behavior — the classical issue force that explains social riots in the French suburbs, banlieues," said Wieviorka. The other issue, said Wieviorka, is the ongoing tension over the French face veil ban. Several hundred women have been caught violating the ban since it became law, although not all have faced penalties. In this latest incident, police say the husband of a woman flouting the ban tried to strangle one of their officers. Local Muslim groups dispute that account. Monday, a teenager was sentenced to six months in prison in connection with the Trappes clashes. Two other defendants were acquitted. The situation in Trappes remains tense but, for the moment, calm. France's Interior Minister Manuel Valls has defended the police response. Interviewed on French radio following the violence, Valls said Trappes residents want order and calm restored and that's what's happening. He saluted what he called exemplary work by the police. Valls also defended the French face veil ban, saying it was not against Islam, but rather was in the interest of women. But the response by France's leftist government has sparked strong criticism — both for being too tough and not tough enough. Politicians from the main, center-right UMP opposition party accuse the government of being too lax. Interviewed on France-Info radio Tuesday, former UMP minister Valerie Pecresse criticized the justice system for not cracking down more swiftly and firmly. What's clear, said sociologist Wieviorka, is that successive governments, both from the left and the right, have failed to alleviate longstanding tensions over immigration and violence. "In front of all these problems at that stage, the only possible answer for the government has been sending in the police, sticking terms of order, in terms of security, respect of the law," Wieviorka stated. For example, Socialist President Francois Hollande made campaign promises to end racially based identity checks and to introduce legislation giving immigrants the right to vote in local elections. So far, Wieviorka says, neither promise has been fulfilled. "So there is a strong feeling that if you live in these neighborhoods, if you are an immigrant, you are Muslim, or you are different, you are not taken seriously into account," said Wieviorka. New reports Tuesday suggest French police are now being probed over racist remarks made on an unofficial police Facebook page at the time of the Trappes violence. France's summer is just beginning. It remains to be seen just how it will end. World gets a first look at the unnamed royal baby By
the A.M. Costa Rica wire services
William and Kate, the Duke and Duchess of Cambridge, presented their baby boy, as yet unnamed, to the world’s media Tuesday. Just a day after his arrival in the world, Britain’s third in line to throne entered the global spotlight in the arms of his mother Kate. The Duke and Duchess of Cambridge stood on the hospital steps, the proud parents of a boy. Unfazed by the attention of the world’s media, William and Kate brought him over to waiting reporters. “He’s got a good pair of lungs on him, that’s for sure. He’s a big boy, quite heavy. But we’re still working on a name so we’ll have that as soon as we can... it’s the first time we’ve seen him really so we’re having a proper chance to catch up," said the prince. “It’s very emotional, it’s such a special time, any parent will I think know what this feeling feels like, added the new mother. Moments later a royal car appeared. William, already getting used to the practicalities of fatherhood, fitted the car seat before driving his new family home. The celebrations had already begun across Britain. The bells of Westminster Abbey, where William and Kate were married in 2011, rang out for three hours across the capital. Earlier, crowds had gathered at Buckingham Palace as the Guardsmen played "Congratulations." Thirty one years ago, William was born at the same London hospital. The echoes of history are a comfort for William after the pain of losing his mother, says royal commentator Richard Fitzwilliams. “William is a very proud father to have his son born at the same hospital he was. Regarding the future, he’s absolutely determined that Kate will face certain pressures in a balanced way, that’s the way it’s been handled so far and it’s been done excellently," he said. Kensington Palace, William’s childhood home, will be the new base for the royal baby. $1.5 million has been spent renovating one of the apartments. It has twenty-one rooms, including a drawing room, staff quarters and a nursery fit for a future king. Despite agreements from the British media to respect the family’s privacy, the baby’s upbringing will be far from normal, says royal author Phil Dampier. “Even if you managed to avoid the paparazzi and went for a walk in the park, there’s always likely to be a member of the public you’re going to bump into who wants to take a picture. So it’s going to be extremely difficult to get any privacy. Fortunately you’ve got the royal residences. And then of course Kate’s got her family home with her parents in Berkshire," he said. And the Middleton family home is where William and Kate are likely to take their son in the coming days, away from the media glare and with the extra care of his grandparents. An overjoyed mother and father getting to know their baby; as a nation celebrates the arrival of its future king. Greenpeace issues complaint against Chinese coal company By
the A.M. Costa Rica wire services
International environmental group Greenpeace is accusing China’s largest state-run coal company of massively exploiting water resources in the country's arid Inner Mongolia region. In a newly released investigative report, the group says wells have dried up, lakes have shrunk and desert dunes are expanding near the company's plant. According to Greenpeace, since state-owned Shenhua Group began extracting water for its plant to process coal into liquid fuels, groundwater levels have dropped by nearly 100 meters. One lake where the plant extracts its water has also shrunk by two-thirds since operations began in 2006. The group says the plant is not only drying up water resources, but illegally dumping toxic industrial wastewater as well. Local farmers and herders are finding it difficult to maintain their livelihoods, sparking social unrest. But the company is in the midst of plans to massively expand the project. Li Yan, the head of the environmental group’s climate and energy campaign in China, said Shenhua needs to put an end to the destruction. “We also want to warn the current ambitious development plans in the local and central governments for more coal chemical projects to take this as an example and to please give water resource limits priority," Li said. China relies heavily on coal to power its massive economy, the world’s second largest, but its leaders are also facing growing demands to address environmental concerns. Earlier this month, China cancelled a $6 billion uranium-processing plant following protests against the facility. Other petrochemical projects have recently been halted as well. The release of the report is the first time that Greenpeace has taken on a single state-owned enterprise with such scrutiny and focus. Greenpeace is not publishing the findings to make the company look bad, said Li, but to make sure that unchecked expansion of the coal industry does not come at the cost of water and ecological security. “This is definitely not risk free and we have tried our best to make sure that our evidence and findings are very solid. And we have also tried to bring evidence and show what is happening to different ministries and policy makers,” said Li. Greenpeace has delivered copies of the report to China’s environmental ministry, water resources ministry and a government body that oversees state-owned enterprises, said Li. The group has not yet received a response. Another copy was sent to the company Tuesday, just before the group held a news conference in Beijing to announce its findings. Shenhua has yet to comment on the report. Its liquid to coal plant in Inner Mongolia is one of three such pilot projects in China. The Greenpeace investigation was based on 11 field trips to the project between March and July of this year. Although the company says the plant is a low water-consumption project that has zero discharge, Greenpeace said, its findings prove those claims are false. The group said it found high-levels of toxic chemicals in discharge wastewater and other cancer causing compounds in sediment samples. The process of converting coal to liquid fuels widens the possible uses of China’s plentiful energy source beyond just producing electricity. As China’s reliance on coal power generation slows, coal companies are looking for other alternatives. Local governments in the northwest are eager to allow such industries to operate because they contribute badly needed tax revenues, said Li. “Right now there are only less than a handful of coal liquefaction projects because it is really controversial for its water intensity, for its energy intensity. This is why these projects are very important, not only for Shenhua, but also for the whole industry. They are really looking at these projects to be the flagship for the modern coal chemical industry,” said Li. But Li added that if pilot projects like Shenhua's are having problems it’s a very worrying sign for their expansion. Currently, more than 100 coal chemical projects are waiting for Chinese government approval to move forward. City life shown to be safer than living in the country By
the A.M. Costa Rica wire services
Contrary to what many believe, living in the city is far less risky than in the country, according to a study released Tuesday that takes into account all major forms of death from injuries. Although homicides in cities far outpace those in rural areas, overall the risk of dying from some form of accident or injury is 20 percent greater in the most rural counties of the United States than in the nation's biggest cities. The findings may give pause to people tempted to flee cities for the bucolic ideal of rural life, says Sage Myers, a pediatric emergency medicine specialist at the University of Pennsylvania and the Children's Hospital of Philadelphia, whose study was published in the Annals of Emergency Medicine. “As you moved further and further away from cities you got less and less safe. Even going into the suburbs dropped your safety a little bit,” she said. “It's a little counterintuitive,” she said. Dr. Myers said when people think of their personal safety, they tend to think about intentionally inflicted injuries, such as being attacked or shot, but the researchers found that the risk of dying from an accidental injury is 40 percent higher in the nation's most rural counties than in its most urban. “It turns out unintentional injuries dwarf intentional injuries,” Myers said, and those types of injuries occur much more often in rural areas. Part of the differences in the study may reflect reduced access to trauma centers, which are staffed with doctors who are trained to handle life-threatening injuries. And since most trauma centers are clustered near large cities, rural dwellers may be more at risk of dying from life-threatening injuries. Dr. Myers and colleagues studied government data on all injury-related deaths from all 3,141 counties across the United States from 1999 to 2006. They excluded deaths caused by the Sept. 11, 2001, attacks, which the researchers deemed too anomalous to be counted. Of the nearly 1.3 million deaths during the study period, the overall rate of deaths caused by accidents was 37.5 per 100,000, compared with 17 per 100,000 for homicide and suicides. The most common causes of injury-related deaths were motor vehicle crashes, which occurred at more than twice the rate in rural areas as they did in cities. Overall, car crashes caused 27.61 deaths per 100,000 people in most rural areas and 10.58 per 100,000 in most urban areas. That may be because people in rural areas are more prone to drive on highways at high speeds, and some studies have shown people in rural areas are less likely to comply with seatbelt and child restraint laws than are individuals in urban areas. When the team looked at firearm-related deaths, they found no significant difference in the overall risk of death between urban counties and rural counties, but there were significant differences in the trends by age. In rural areas, for example, children aged up to 14 and adults over 45 had the highest risk of dying from a firearm injury, but among adults aged 20 to 44, the risk of a firearm-related death was much higher in urban areas, and the risk was about the same for youths aged 15 to 19, regardless of where they lived. The study did not look at the number of people who were injured but survived their car crashes or gunshot wounds, which might reflect whether people in urban areas simply have better access to healthcare than people in rural areas who have life-threatening injuries. Dr. Myers said more study is needed to tease out the differences in risks between urban and rural areas, but she said such studies should be taken into account as health policy experts consider the placement of new trauma centers. Report says drones in Pakistan killed many more civilians By
the A.M. Costa Rica wire services
A British media outlet says a classified Pakistani government report shows U.S. drone strikes on militant targets in Pakistan have killed many more civilians than Washington has acknowledged. A U.S. official rejected the document's claim, saying it lacks credibility. The non-profit Bureau of Investigative Journalism said Tuesday it obtained the Pakistani report from anonymous sources and published the full version on its Web site. The document lists U.S. drone strikes between 2006 and 2009 and shows at least 147 civilian deaths from the attacks, representing about one-fifth of total fatalities. It says most of the rest were militants. A similar study issued this month by the New America Foundation said U.S. drones killed 191 civilians in the four-year period, from a total of 1,004 fatalities. The Washington-based public policy institute said the casualty figures were based on credible reports mostly from Western news agencies. In a statement, U.S. official said "the notion that the United States has undertaken operations in Pakistan that resulted in the deaths of hundreds of innocent Pakistanis is ludicrous." The official said the Pakistani document listing drone casualties is not credible because it relies in part on erroneous media reporting. The U.S. Central Intelligence Agency has carried out hundreds of drone strikes on militants in Pakistani tribal regions since 2004, to stop them from attacking U.S. troops in neighboring Afghanistan. U.S. officials have said the drone strikes killed only about 50 non-combatants. Pakistan's federally administered tribal areas have long been inaccessible to independent media, making it difficult to verify the identities of drone casualties. Pir Zubair Shah, a former New York Times journalist who reported from Pakistan, said it also is hard for Islamabad to confirm the casualties of drone attacks on militant-controlled districts. "The government itself has as many problems of accessibility as anybody else would have, like a journalist or a human rights worker, or anyone who wants to investigate anything in the tribal areas," he said. Shah, who is from the South Waziristan tribal region and now lives in New York, said independent access to government-controlled tribal territory is heavily restricted as well. He said Pakistani authorities block roads to prevent reporters from discovering civilian casualties caused by Pakistani military operations. Shah said the Taliban imposes similar road restrictions to stop journalists from learning about militant training camps and its sheltering of al-Qaida terrorists from U.S. drones. "After a typical strike, the Taliban cordons off the area. They take the dead bodies and make sure that if there is an important person, that he is buried as soon as possible, especially outsiders, foreigners like al-Qaida, Uzbeks and others," he said. Shah said the immersion of Taliban fighters into the daily life of tribal communities also has blurred the line between militants and civilians. He said fighters often recruit teenagers and share living compounds with family members not directly engaged in combat. The Pakistani government had no immediate response to the Bureau of Investigative Journalism's report. Researchers say that dolphin call each other by name By
the A.M. Costa Rica wire services
Dolphins call each other by names, according to a new study. The study of 200 bottlenose dolphins indicated that they are the only animals other than humans to use individual names, according to the research from the Sea Mammal Research Unit at the University of St. Andrews in Scotland. In study, co-authors Vincent Janik and Stephanie L. King reported that dolphins have signature whistles they use as greetings when meeting up. The researchers say individual dolphins have individual whistles or names. The two researchers recorded the whistles of 12 dolphins and played the whistles back to each dolphin to record their reactions. According to the study, in eight of 12 cases, the dolphin replied when they heard their own whistle. In two cases, the dolphin responded to the whistle of a dolphin from its own pod -- the group of other dolphins it travels with. The study said none of the dolphins responded to the sound of a dolphin it did not know. "Here, we show that wild bottlenose dolphins respond to hearing a copy of their own signature whistle by calling back," the researchers say in their study abstract. "Animals did not respond to whistles that were not their own signature. This study provides compelling evidence that a dolphin's learned identity signal is used as a label when addressing conspecifics. Bottlenose dolphins therefore appear to be unique as nonhuman mammals to use learned signals as individually specific labels for different social companions in their own natural communication system." The study, "Bottlenose Dolphins Can Use Learned Vocal Labels to Address Each Other," was published in Proceedings of the National Academy of Sciences. . |

Some diabetes drugs
labeled natural are not, FDA says By
the A.M. Costa Rica wire services
U.S. health regulators are cracking down on 15 companies for selling products they say falsely claim to cure or mitigate the symptoms of diabetes. The U.S. Food and Drug Administration sent letters last week to 10 domestic and five foreign companies, warning them that their products violate the law. A total of 20 products are covered by the warning letters. In some, treatments are being sold as natural when in fact they contain pharmaceutical ingredients, the FDA said. In other cases, prescription drugs are being sold to patients without a prescription, and in some cases products are falsely claiming to cure or mitigate the symptoms of the disease. The products are being sold online and in retail outlets, the agency said, though it could not say how many stores the products are sold in or how many have been distributed online. But Howard Sklamberg, director of the office of compliance in the FDA's drugs division, said he considers health care fraud in general, and health care fraud involving diabetes products in particular, as a large problem. The FDA said three of the most potentially dangerous cases it had targeted involve unapproved products originating in Asia that contain pharmaceutical ingredients not disclosed on the product labels. These products are called Diexi, which was shipped from India, Insupro Forte, which was shipped from Malaysia, and Jiang Tan Yi Huo Su Jiao Nang, which the FDA said translates as Anti-diabetic Pancreatic Capsule and was shipped from China. Diexi, made by Amrutam Life Care, is marketed on the company's Web site as an “anti-diabetic herbal formula that provides an effective treatment to relieve all symptoms related to diabetes.” According to the FDA's testing, however, Diexi contains metformin, a pharmaceutical approved in the United States to treat diabetes under a physician's supervision. Another drug, Insupro Forte, is advertised by Easy Pha-max as “Truly Savior of Diabetics.” The company claims the product is made with a plant-based protein that helps bring down blood sugar levels and repairs physically altered cells. In fact, the product contains glyburide, an FDA-approved diabetes medication that can cause serious side effects including low blood sugar if not taken properly, the agency said. Testing showed that the Anti-diabetic Pancreatic Capsule contained metformin, glyburide and phenformin. Phenformin was removed from the U.S. market in 1978 because it was associated with lactic acidosis, a serious condition that can cause weakness, tiredness, muscle pain, trouble breathing and a sudden slow or irregular heartbeat. The companies could not be immediately reached for comment. “Diabetes is a serious chronic condition that should be properly managed using safe and effective FDA-approved treatments,” FDA Commissioner Margaret Hamburg said in a statement. “Consumers who buy violative products that claim to be treatments are not only putting themselves at risk, but also may not be seeking necessary medical attention, which could affect their diabetes management.” Nearly 26 million Americans have the disease, which can lead to heart disease, blindness, kidney failure, and amputations of the lower limbs. If the firms do not comply with the law, the FDA can take action to prevent the products from being imported from overseas, and it can seize those made domestically and initiate criminal proceedings |

From Page 7: Rental eviction bill gets first OK By
the A.M. Costa Rica staff
Lawmakers acted Tuesday to put an end to what they called the long and tortuous process of evicting a tenant who does not pay the rent. The legislature passed on first reading a measure that would allow a landlord to take action if a renter missed payments for two months. The subsequent legal process would be oral and rapid, according to the summary of the law, The Partido Liberación Nacional said that the bill had been a priority with the party. The quick action also covers a renter who overstays the term of an expired lease. The owner will not be frustrated in his right to receive a just rent, said the party in a release. The proposed law is No. 17.527. A second and final vote is likely next week. The inability to evict a tenant who has not paid or has stayed longer than the lease allows has been a major problem for landlords. The courts have not moved quickly to address this issue, and there is no guarantee under the proposed law that judges will act quickly, even though they are supposed to do so. And there are a number of ways renters can stymie efforts to remove them. The proposed law also covers situations in which the rental is made for promises of services in lieu of money. |
