Employers propose
tiny wage hike
By
the A.M. Costa Rica staff
The business sector has proposed a 1.33 percent increase in the minimum wages as of July 1. The proposal was received with surprise, said the Unión Nacional de Trabajadores, which is on the other side of the table. Labor interests have proposed an increase of more than 4 percent. The presentation to the Consejo Nacional de Salarios, was by the Unión Nacional de Cámaras y Asociaciones del Sector Empresarial Privado. There is another meeting Monday when the government will present its proposal. The increase will be reflected for most workers in the July 15 paycheck, although the minimum wages also cover day workers. Many Costa Ricans work for the minimum wage that is set by the government. Each job classification has its own salary. Midyear vacation will begin next Monday By
the A.M. Costa Rica staff
Midyear public school vacations begin Monday for two weeks, and the tourism industry is ready. Also prepared are the various museums and private clubs that set up programs for youngsters. Police also said they will be on their toes until vacation ends July 11. Some private schools, such as Country Day School in Escazú, are not affected because they are on a different calendar. Country Day uses the U.S. system, and the school has already ended its class year. The vacation was part of the demands of striking teachers who did not work for a month. The teacher negotiators demanded the vacation continue even though youngsters had missed weeks of school. The government agreed. ![]() Ministerio de Gobernación,

Woodland mystery
at Barra del Colorado
By the A.M. Costa Rica staff
In the woods at Barra del Colorado is extreme northeast Costa Rica, officials have a bit of a mystery. Someone cut most of the growth on four hectares of land in a sector known as Caño Pereira. The region is part of Pococí, Limón. The land is believed to be public property, but there are major restrictions on cutting trees and shrubs. The Fuerza Pública said that a frog that is in danger of extinction lives in the area. The Ministerio de Ambiente y Energía is involved both because of the frog and because of the clear cut woodlands. Police found a shack and a tent that were unoccupied on the site along with some shotgun shells. Similar activities elsewhere, such as in the Talamancas, would suggest the beginnings of a marijuana farm. But cultivating the weed might not be successful in the this region around the Río San Juan. Diplomats in D.C. caught World Cup fever By
the A.M. Costa Rica wire services
A red sea of about 100 diplomats, family and embassy friends wearing their national color, packed into the Korean cultural center to cheer on their team in a World Cup match against favored Russia last week. It was just a brief stroll down Washington D.C.’s Massachusetts Avenue from the Korean embassy to the affiliated cultural center, which had set up giant TV screens in two rooms. But it was a big Embassy Row leap from the normal diplomatic routine, as some Korean embassy officials abandoned their formal reserve and thrust their hands in the air to cheer when team Korea scored a critical goal. Some diplomats shed their suit jackets, opting to put on over their shirt and tie, bright red T-shirts emblazoned in Korean with words “Korea Fighting” for the soccer game. Perhaps no group of officials here in the American capital has embraced World Cup fever more than the diplomatic community. Televisions are turned on during national games, even during the work day. Diplomats speculate around the water cooler about competitors in their nation’s group and follow the action on computer monitors and smart phones. Some surreptitiously listen to games of interest and obsessively check World Cup scores. This summer, Washington’s diplomatic community has collectively come down with World Cup fever. Their workday soccer enthusiasm is reminiscent of American office workers, who are famous for office pools, internet game monitoring and lost productivity during the “March Madness” of the NCAA college basketball tournament. Aiding the diplomatic World Cup mania, soccer is also increasingly popular among the locals in Washington and featured in many restaurants and bars. American fans in the nation’s capital area sport red, white and blue American flag apparel and chant “USA! USA!” during games against Ghana and Portugal. For those assigned to represent their nation in a foreign capital, the World Cup is a source of national pride far away from home. For example, this game where Korea accomplished an unexpected tie with Russia. That was good enough for one embassy diplomat to take to heart. Korea has been rocked by the drowning of high school students in a horrific ferry boat incident. The nation has long been saddened, a Korean diplomat noted, but the World Cup provided a momentary lift from tragedy. “We had a good game,” the diplomat said. “Now we are very happy.” All of a half dozen embassies queried about their World Cup activities reported staff would be watching or monitoring the matches. At the Netherlands embassy, diplomatic staffers wore orange ties, socks and other items to mark their World Cup games. At half-time of one World Cup game, ambassador Rudolf Bekink retweeted a picture of a flag that declared, “Our Roots Are Orange.” With some initial success, the Dutch national team’s embassy fans became especially captivated by the Cup. “In the midst of other regular work,” reported embassy press officer Carla Bundy, “there are people at the canteen and at the coffee and the office and the cooler, talking about the Dutch national team.” In fact, the Netherlands Embassy played upon the World Cup excitement to promote their nation in Congress. The Dutch actually built a miniature indoor soccer field in a Capitol Hill office building, complete with artificial turf. Congressional aides were offered famous Dutch Heineken beer, as well as American ice cream and widescreen TV’s showing the Netherlands vs. Spain match. As for Spain, its diplomatic personnel watched another midday game last week in the basement of the embassy on a “big, big TV,” according to spokesman Gregorio Laso. Some Spanish embassy staffers even started work at the very undiplomatic hour of 7 a.m., Laso explained, so “they could finish their job and watch the match.” Though Spain has been known for its leisurely mealtimes, Laso skipped lunch so he could watch the 3 p.m. game versus Chile. For Chile, “I think we are not going to be working at the time of the game,” a Chilean diplomat admitted honestly, but privately. “We get very patriotic” over the matches. “I think everyone is taking the time to watch their country play,” she observed. “This whole month everyone’s going to be talking about soccer.” At the Mexican embassy, the World Cup “can bring out a lot of passion and enthusiasm rallying behind our national team,” deputy embassy spokesman Vanessa Calva noted. “Some of our colleagues have been wearing our Mexican decorations…My mind has been rather busy about talking soccer.” Fittingly, perhaps the most extreme World Cup diplomatic celebrant in Washington was Brazil, the host country and a major soccer power at the start of the competition. The Brazilian ambassador in Washington threw a huge party for the start of Brazil’s Cup play, with the signature national caipirinha drinks. But that was just the beginning of Brazilian diplomatic devotion to their World Cup matches. For those dialing the embassy after 1 p.m., a couple of hours before Brazil’s game with Mexico, the phone went unanswered. It seems the entire embassy was closed: for the soccer holiday.

started just
before sunset and they also scheduled a trail guide for the following
day. Police will continue searching for Ms. Kremers until they begin looking into any potential criminal involvement that may have played into the abrupt disappearances. “Right now no one is under investigation,” Ms. Pittí said. “It's still too early for us to make any hypotheses.” Recently the jungle area surrounding El Pianista has gotten heavy rains, making some parts inaccessible. Ms. Pittí said up to 30 investigators will continue searching for Ms. Kremers despite discouraging evidence and the harsh jungle conditions. “We are not going to suspend the search. We are going to keep searching as we've been doing,” she said. “But since we're working on a dangerous terrain we need to do things correctly.” Last week police discovered a backpack with key possessions from the woman near the flooded Río Culubre. Days after the pack was found with cell phones and a digital camera allowed officers to narrow their search, investigators came across hiking boots belonging to the women. Ms. Froon's remains were found an estimated eight hours walk from the beginning of El Pianista. |
Stone balls and related sites in Osa finally get U.N.
recognition |
|
By
the A.M. Costa Rica staff
with wire service reports The U. N. Educational, Scientific and Cultural Organization has added four Costa Rican sites in the Municipalidad de Osa to its World Heritage List These are sites most commonly recognized for the giant stone spheres, but they also contain unique burial sites and man-made mounds. A committee halfway around the world in Qatar made the inclusion official Monday. To celebrate, President Luis Guillermo Solís visited the stone spheres on display at Museo Nacional. He said the sites' adoption into the U.N. list reaffirms that these cultural treasures are crucial to Costa Rica's identity. “The cultural and archaeological heritage of a country is fundamental not just because it represents a defining time in its history, but also because of an undeniable importance for its memory – a mirror that we can look back in to see our past glory,” Solís said. The inclusion of stone sphere sites to the list was basically a formality. The previous administration submitted candidacy for the spheres and visits from United Nations evaluators followed. Much of the excavation and application work was supervised by Francisco Corrales, museum archaeologist. The tourism minister, Wilhelm von Breymann, was also on hand. He said Osa and the country's southern sector should see a boost in tourism as a result of the addition to the list. “With great pleasure we celebrate this important news for our country which will benefit the southern region,” von Breymann said. “This will have an impact on the positioning of this important region for tourism.” The sites are deemed property of the global community, giving them a touristic allure. Museo Nacional representatives said a full-scale plan of preservation is already in place to protect the Deltas del Diquís sites. A museum already has been constructed on Finca 6. The other three archaeological sites are Batambal, El Silencio, and Grijalba 2. They are near Palmar Sur. This is the first group of cultural sites for the country. Costa Rica already has three sites located on The U.N. nature list: the Talamanca Range/La Amistad National Park, Parque Nacional Isla del Coco and Area de Conservación Guanacaste. The U.N. agency said this about the sites: The "Precolumbian chiefdom settlements with stone spheres of the Diquis includes four archaeological sites located in the Diquis Delta in southern Costa Rica, which are considered unique examples of the complex social, economic and political systems of the period between 500-1500 AD. "They contain artificial mounds, paved areas, burial sites and, most significantly, a collection of stone spheres, between 0.7m and 2.57m in diameter, whose meaning, use and production remain largely a mystery. "The spheres are distinctive for their perfection, their number, size |

Their preservation from the looting that befell the vast majority of archeological sites in Costa Rica has been attributed to the thick layers of sediment that kept them buried for centuries." World Heritage Sites are determined by the U.N. Educational, Scientific and Cultural Organization to have special cultural or natural significance and meet the criteria. A total of 26 sites were added to the list Monday, including 21 cultural sites, four natural sites and one mixed site. According to the U.N. agency, the total number of sites now on the list is 1,007. These include 779 cultural sites, 197 natural sites and 31 mixed sites. Perhaps the most well-known new addition is the Grotte Chauvet-Pont d’Arc, Ardèche, France, a cave that contains the earliest known examples of prehistoric cave art. The drawings, which are thought to be over 30,000 years old, include more than 1,000 depictions of mammoths, lions, bears, other animals and human hands Other sites added by UNESCO span the globe and include the Pyu Ancient Cities, the first World Heritage site in Myanmar, also known as Burma. China’s Grand Canal was also added to the list. Construction of the massive water system was started in the 5th century BC, and stretches from Beijing to Zhejiang province. The Grand Canal, which served as China’s inland transport system was the “most extensive civil engineering project prior to the Industrial Revolution,” according to the agency. The U.S. saw the addition of the ancient earthworks at Poverty Point, Louisiana, added to the list. The complex is made up of several mounds and ridges likely used in as living areas and for ceremonial purposes, according to the agency. The earthworks were built between 3,700 and 3,100 BC “by a society of hunter fisher-gatherers." Three natural properties were also added to the World Heritage list, including Mount Hamiguitan Range Wildlife Sanctuary in the Philippines, the Okavango delta in Botswana and the Stevns Klint geological site in Denmark.

Sunscreen for children dramatically cuts later skin cancer,
study shows |
|
By
the Texas Biomedical Research Institute news staff
Research conducted at the Texas Biomedical Research Institute has established unequivocally in a natural animal model that the incidence of malignant melanoma in adulthood can be dramatically reduced by the consistent use of sunscreen in infancy and childhood. According to senior author John L. VandeBerg, the research was driven by the fact that, despite the increasing use of sunscreen in recent decades, the incidence of malignant melanoma, the most aggressive form of skin cancer, continues to increase dramatically. The American Cancer Society estimates that more than 75,000 new cases of melanoma will be diagnosed in the U.S. this year. The research was published in the scientific journal Pigment Cell and Melanoma, “While sunscreen is highly effective in preventing sunburn, this paradox has led some to question whether sunscreen is effective in preventing melanoma caused by ultraviolet light,” VandeBerg said. “It has been suggested that sunscreen enables people to receive more UV exposure without becoming sunburned, and that increased exposure to UV light has led to an increasing incidence of melanoma.” Questions regarding the effectiveness of sunscreen have remained unanswered in part because, until recently, no natural mammalian model of UV-induced melanoma has existed, noted VandeBerg. Scientists at Texas Biomedical Research Institute have established the |
gray short-tailed
opossum, a small marsupial from South America, as
such a model, and tested an over-the-counter facial lotion containing
SPF15 sunscreen for its ability to prevent UV-induced melanoma. The Texas Biomed researchers found that the application of lotion containing sunscreen to infant opossums led to a 10-fold reduction in pre-melanotic lesions known to progress to melanoma, in comparison to infant opossums receiving lotion that did not contain sunscreen. This difference in the development of lesions occurred even when low doses of UV light were applied – so low that they caused no sunburn or even reddening of the skin in the opossums that did not receive sunscreen. The pre-melanotic lesions did not appear until the infants had become adolescents equivalent to early teenagers in humans, and prior experiments established that the pre-melanocytic lesions in opossums do not progress to melanomas until the animals are well into adulthood, as typically occurs in humans. “Based on these results, we speculate that the reason it is particularly important that sunscreens be used consistently in childhood, and especially in infancy, is because skin cells during growth are dividing much more rapidly than in adulthood, and it is during cell division that the cells are most susceptible to UV-induced damage,” said VandeBerg. “Evidence that supports this hypothesis is that melanoma is not induced in adult opossums when their shaved skin is irradiated by UV light in the absence of sunscreen.” |

Sentences for journalist trio giving Egypt a black eye By the A.M. Costa Rica wire services
An Egyptian court has sentenced three Al Jazeera journalists to seven years each in prison on charges of supporting the banned Muslim Brotherhood and spreading false news, in a case that has drawn international condemnation. The three sentenced Monday in Cairo include Australian Peter Greste, Egyptian-Canadian Mohamed Fahmy and Egyptian Baher Mohamed, who was given an extra three years on another charge. Speaking to reporters in Baghdad Monday, U.S. Secretary of State John Kerry harshly criticized the ruling a day after speaking with Egyptian leaders in Cairo. "Today's conviction is obviously a chilling and draconian sentence," Kerry said. In Geneva, United Nations human rights chief Navi Pillay, in a statement, called for the reporters' release, accusing Egypt of crushing the media. She said she was shocked and alarmed by the verdicts and heavy jail sentences handed down to three Al-Jazeera journalists. Ms. Pillay's statement said media in Egypt should be protected not prosecuted. The commissioner urged authorities to promptly release them and other media workers imprisoned for doing their job. Egypt rejected foreign criticism of its judicial system in a statement Monday, saying it considered the remarks interference in its internal affairs. Al Jazeera has always denied the charges against its employees. The network's acting general director, Mostefa Souag, called the verdict shocking and said Al Jazeera will continue its international campaign to free its journalists. Al Jazeera English Managing Director Al Anstey said the sentences were given despite not a shred of evidence to support the charges and that the only sensible outcome is for the verdict to be overturned. Officials at The Hague and in London have summoned the respective Egyptian ambassadors over the sentences. In Canberra, Australian Foreign Minister Julie Bishop said the decision does not support Egypt's claim to be on a transition to democracy. "The Australian government urges the new government of Egypt to reflect on what message is being sent to the world about the situation in Egypt," Bishop said. "Freedom and freedom of the press is fundamental to a democracy, and we are deeply concerned that this verdict is part of a broader attempt to muzzle the media freedom that upholds democracies around the world." Greste, Fahmy and Mohamed were arrested in December at a Cairo hotel where they were working after Egyptian authorities closed the Qatar-based television network's bureau. Last week, Egypt freed another Al Jazeera journalist who spent 10 months in prison without being charged. Prosecutors ordered the release of Abdullah Elshamy for health reasons after a hunger strike that he began in January to protest his detention. Egyptian authorities have carried out a crackdown on the Brotherhood since Sissi, then the army chief, led the ouster of president Mohamed Morsi last July. The crackdown included violently dispersing protests and arresting many of the Brotherhood's leaders. Since Morsi's ouster, Egypt has drafted a new constitution and voted Sissi into office, and plans to hold parliamentary elections later this year. Dish array in Chile set to search for cold objects By the A.M. Costa Rica wire services
Astronomers have a new powerful tool for looking deep into space while trying to better understand the origins of the universe. It is a new telescope that will look for signals coming from the coldest objects in deep space. The telescope is called Atacama Large Millimeter/sub-millimeter Array or ALMA. The last of its 66-dish antennas has been moved to its site in Chile's high desert Under an almost always cloudless sky, in Chile's cold and barren Atacama desert, 5,000 meters above sea level and away from any electromagnetic interference, ALMA’s dish antennas listen to signals coming from distant cold objects. Even the coldest matter in space, such as dust and gas, emit signals between infrared light and radio waves, with wavelengths smaller than a millimeter. Catching them requires either a dish antenna of enormous proportions, or an array of smaller ones, with a supercomputer to consolidate the data. The equipment that receives those signals must be kept at even colder temperatures, says astronomer Gianni Marconi. “You have to amplify the signal that is really really low in conditions that are really really extreme, so this is the reason because of our detectors are kept at the minimum temperature possible," he said. "We are few degrees above the zero absolute.” Signals from ALMA’s 66 antennas are processed in a supercomputer called Correlator. Electronic engineer Lorenzo Martinez says each of its four parts can process a lot of data. “We have 120 gigabytes per second that is produced in each antenna," he said. "Well, if you do the math, these are astronomical numbers.” It is tricky to combine the signals from several dish antennas. Scientists have to periodically rearrange them in order to find the best configuration with the least amount of radio interference. Juan Carlos Salamanca operates a special multi-wheeled transporter to move the antennas across the flat desert floor. “One antenna weighs almost 100 tons and you need to transport it to 5,000 meters and the truck needs to have the capability to work without a problem at 5,000 meters,” he said. Marconi says the ALMA telescope will open a new window on the most distant early formed galaxies. ALMA is a joint project funded by Europe, United States, Canada, East Asia and Chile. U.S. says illegal children will not become citizens By the A.M. Costa Rica wire services
The United States is telling Central American parents there is no path to American citizenship for the thousands of unaccompanied children who are entering the U.S. illegally in hopes of escaping poverty and crime in their native lands. In an open letter to parents published in Spanish-language outlets over the weekend, U.S. Homeland Security Secretary Jeh Johnson said no permits to stay in the U.S. are being granted to the 47,000 children who have crossed into the country this year. Most of the children have come from Honduras, El Salvador and Guatemala, traveling through Mexico to the southwestern border of the U.S. Johnson said the U.S. is seeking to deport the children, although they currently are being held in several U.S. facilities while their cases are considered by U.S. immigration judges. Johnson did not say so in the letter, but some of the children could be allowed to stay if their parents are already in the U.S. He said the desire to see a child have a better life in the United States is understandable, but he said the risks of illegal migration are far too great. The Homeland Security chief warned the parents that it is dangerous to send their children on the long journey to the U.S., and that criminal smuggling networks have no regard for their safety. He said that for the smugglers, "your child is a commodity to be exchanged for a payment." An estimated 11 million illegal immigrants are already in the U.S. and immigration policies are politically contentious. Last year, the Senate approved reforms that could over years allow many of the illegal immigrants to become U.S. citizens, but the legislation has languished in the House of Representatives and no votes on reforms have been scheduled. Johnson said only children who arrived in the U.S. before mid-2007 are eligible to stay. ![]() Massachusetts Institute of Technology

The new 36-core chip is
tiled, meaning that it simply repeats the same circuit layout 36 times.
Tiling makes multicore chips much easier to design.Researchers
create chip
with 36 core processors By the Massachusetts Institute of
Technology News Office
The more cores or processing units a computer chip has, the bigger the problem of communication between cores becomes. For years, Li-Shiuan Peh, a research professor at Massachusetts Institute of Technology, has argued that the massively multicore chips of the future will need to resemble little Internets, where each core has an associated router, and data travels between cores in packets of fixed size. This week, at the International Symposium on Computer Architecture, Peh’s group unveiled a 36-core chip that features just such a network-on-chip. In addition to implementing many of the group’s earlier ideas, it also solves one of the problems that has bedeviled previous attempts to design networks-on-chip: maintaining cache coherence, or ensuring that locally stored copies of globally accessible data remain up to date. In today’s chips, all the cores — typically somewhere between two and six — are connected by a single wire, called a bus. When two cores need to communicate, they’re granted exclusive access to the bus. But that approach won’t work as the core count mounts: Cores will spend all their time waiting for the bus to free up, rather than performing computations. In a network-on-chip, each core is connected only to those immediately adjacent to it. “You can reach your neighbors really quickly,” says Bhavya Daya, a graduate student and first author on the new paper. “You can also have multiple paths to your destination. So if you’re going way across, rather than having one congested path, you could have multiple ones.” One advantage of a bus, however, is that it makes it easier to maintain cache coherence. Every core on a chip has its own cache, a local, high-speed memory bank in which it stores frequently used data. As it performs computations, it updates the data in its cache, and every so often, it undertakes the relatively time-consuming chore of shipping the data back to main memory. But what happens if another core needs the data before it’s been shipped? Most chips address this question with a protocol called snoopy, because it involves snooping on other cores’ communications. When a core needs a particular chunk of data, it broadcasts a request to all the other cores, and whichever one has the data ships it back. If all the cores share a bus, then when one of them receives a data request, it knows that it’s the most recent request that’s been issued. Similarly, when the requesting core gets data back, it knows that it’s the most recent version of the data. But in a network-on-chip, data is flying everywhere, and packets will frequently arrive at different cores in different sequences. The implicit ordering that the snoopy protocol relies on breaks down. Daya, Peh, and their colleagues solve this problem by equipping their chips with a second network, which shadows the first. The circuits connected to this network are very simple: All they can do is declare that their associated cores have sent requests for data over the main network. But precisely because those declarations are so simple, nodes in the shadow network can combine them and pass them on without incurring delays. Groups of declarations reach the routers associated with the cores at discrete intervals — intervals corresponding to the time it takes to pass from one end of the shadow network to another. Each router can thus tabulate exactly how many requests were issued during which interval, and by which other cores. The requests themselves may still take a while to arrive, but their recipients know that they’ve been issued. During each interval, the chip’s 36 cores are given different, hierarchical priorities. Say, for instance, that during one interval, both core 1 and core 10 issue requests, but core 1 has a higher priority. Core 32’s router may receive core 10’s request well before it receives core 1’s. But it will hold it until it’s passed along 1’s. This hierarchical ordering simulates the chronological ordering of requests sent over a bus, so the snoopy protocol still works. The hierarchy is shuffled during every interval, however, to ensure that in the long run, all the cores receive equal weight. Cache coherence in multicore chips “is a big problem, and it’s one that gets larger all the time,” says Todd Austin, a professor of electrical engineering and computer science at the University of Michigan. “Their contribution is an interesting one: They’re saying, ‘Let’s get rid of a lot of the complexity that’s in existing networks. That will create more avenues for communication, and our clever communication protocol will sort out all the details.’ It’s a much simpler approach and a faster approach. It’s a really clever idea.” “One of the challenges in academia is convincing industry that our ideas are practical and useful,” Austin adds. “They’ve really taken the best approach to demonstrating that, in that they’ve built a working chip. I’d be surprised if these technologies didn’t find their way into commercial products.” After testing the prototype chips to ensure that they’re operational, Daya intends to load them with a version of the Linux operating system, modified to run on 36 cores, and evaluate the performance of real applications, to determine the accuracy of the group’s theoretical projections. At that point, she plans to release the blueprints for the chip, written in the hardware description language Verilog, as open-source code. Big Bang theory faces gravity wave questions By the A.M. Costa Rica wire services
The universe expanded so fast in its first moments of existence that it left ripples in the fabric of space-time. Or maybe it didn’t. In a study that could explain what put the bang in the Big Bang, researchers say they have detected the remnants of gravitational waves that fluttered through the universe in an infinitesimally brief period after the Big Bang. Albert Einstein predicted the existence of those waves in his theory of general relativity. If they exist, they would move scientists closer to a unified theory encompassing all the fundamental forces of the universe, from gravity to quantum physics. When the results were first announced in March, experts said they were likely Nobel Prize-worthy if they held up to scrutiny. They had not, however, gone through the customary peer review process before publication in a scientific journal. When outside experts looked at the data, they suggested that interstellar dust could account for the findings. “It’s an extraordinary result. It requires extraordinary scrutiny,” said Johns Hopkins University astronomer Marc Kamionkowski, who was not involved in the study. The findings in question are now published in the journal Physical Review Letters. Working at a radio telescope at the South Pole, the researchers describe a twisting pattern in the background radiation of the universe. That radiation is the energy left over from the Big Bang nearly 14 billion years ago. The twisting pattern is evidence of gravitational waves, the authors say, and they contend that the signal is likely too strong to be dust alone. Other researchers are following up on the results with different instruments. “We’ll have to wait six months, maybe a couple of years, until we have additional data,” Kamionkowski said. “If what they’re seeing really is gravitational waves, whatever uncertainty we have now should decay away.” “This is the way science works,” he added. “Things are not true because somebody claims that they’re true. Things are true because different people make independent measurements and independently arrive at similar conclusions.” And that is still a ways off, he said. Moscow seeks World Trade action on sanctions by U.S. By the A.M. Costa Rica wire services
Moscow is challenging the sanctions imposed on it by the United States and European Union for its involvement in the Ukraine crisis. Russian Prime Minister Dmitri Medvedev said Friday that Russia has sent a communique to the World Trade Organization declaring the sanctions violate international law and World Trade regulations, and he promised a formal complaint will follow. However, Medvedev said chances are slim that the Kremlin strategy will succeed because the United States has great influence at the World Trade Organization. A spokesman for the U.S. Trade Representative said the United States took its obligations under the World Trade Organization very seriously. "Prior to instituting the sanctions against the Russian Federation, the United States carefully considered their consistency with WTO rules,'' he said. Also Friday, the United States added seven pro-Russia separatist leaders to its list of individuals and organizations subject to sanctions over the rebellion in Ukraine, the Treasury Department announced. The West imposed sanctions after the Kremlin annexed Crimea in March. Since then, the Group of Seven leading industrialized nations has considered strengthening the sanctions because of Russian actions seen as interference in Ukraine's internal affairs. The sanctions, aimed at business leaders and companies close to Russian President Vladimir Putin include travel bans against individuals and other prohibitions against companies considered to play a role in economic and political pressure on Ukraine. Some Russian firms have been barred from accessing their assets held in the West, and the global credit companies Visa and MasterCard have suspended relations with Russian banks. Economic analysts say the Western sanctions have driven Russia's economy to the brink of recession. Reuters reports the Russian government has begun to tap a multibillion-dollar welfare fund intended to finance a growing deficit in state-provided pensions. President Vladimir Putin previously said last year that the "national welfare fund," built up from windfall oil revenues, would not be used for other purposes. |

the A.M. Costa Rica staff
Technology giant Toshiba is joining forces with Costa Rica to open a local headquarters in
This marks yet another business that has been attracted to doing business in Costa Rica since President Luis Guillermo Solís took office. He said he thanks Toshiba on behalf of Costa Rica for putting its trust into the nation's workforce and resources. The minister of Ciencia, Tecnología, y Telecomunicaciones, Gisela Kopper, said the government supports the philosophic ideas of how Toshiba products promote themselves to help make people's lives easier. “Initiatives like the ones we celebrate today are crucial to conceptually open a world of possibilities where responsible automation can free a person from daily tasks and allow them to concentrate on more central problems,” she said. Other regional Toshiba headquarters are located in Argentina, Chile, Colombia, Mexico, and Peru. |
