Sao Paulo: Whistle-blower website WikiLeaks has published the names of more than 29 members of Brazilian President Dilma Rousseff’s administration who were spied on by the US National Security Agency at the start of her first term in office, which began in January 2011.

The release of the list of phone numbers on Saturday linked to high-level Brazilian officials comes just days after Rousseff, who was reelected to a second term late last year, and US counterpart Barack Obama met in Washington to end bilateral tensions stemming from previous revelations about NSA eavesdropping on Brasilia.

The June 30 meeting initially been scheduled for October 2013, but Brazil canceled it after former US intelligence contractor Edward Snowden released documents showing that the NSA intercepted Rousseff’s personal communications.

NSA also targeted Brazilian government ministries and the country’s state-owned oil company, Petrobras, those previously released documents showed.

The list disclosed on Saturday by WikiLeaks said that in addition to Rousseff the NSA also spied on the communications of 29 other members of her administration, including her former chief of staff, Antonio Palocci, and erstwhile foreign minister, Luiz Alberto Figueiredo Machado.

The document also said that members of Rousseff’s economic team and Brazil’s ambassadors to Germany, France, Switzerland, Belgium and the US were targets of the wiretapping.

Julian Assange“Our publication today shows the US has a long way to go to prove its dragnet surveillance on ‘friendly’ governments is over,” WikiLeaks founder Julian Assange said in a statement.

“The US has not just (been) targeting President Rousseff but the key figures she talks to every day.”

“If President Rousseff wants to see more US investment in Brazil on the back of her recent trip as she claims, how can she assure Brazilian companies that their US counterparts will not have an advantage provided by this surveillance?” Assange asked rhetorically.

Assange has been holed up at the Ecuadorean Embassy in London to avoid extradition to Sweden for questioning on allegations of sexual misconduct.

Assange, who denies the sexual-misconduct accusations, fears that once he is in Swedish custody, US prosecutors would indict him for the release of secret documents and Washington would pressure Stockholm into handing him over.

  • Indulging in smoking or drinking alcohol may not only damage your teeth but also lead to increased incidences of failure in dental fillings, warned researchers.

The findings, led by researchers from the University of Pittsburgh, showed that within two years of the dental procedure, Dental fillings failed more often in patients who drank alcohol, while the overall filling failure rate was higher in men who smoked.

Furthermore, people with a difference in the gene for matrix metalloproteinase (MMP2) — an enzyme found in teeth — were at increased risk of Dental filling failure.

This could be because MMP2 might be able to degrade the bond between the filling and the tooth surface, potentially leading to failure, the researchers said.

The results, published in the journal Frontiers in Medicine, suggest that genetic analysis might help dentists to personalize treatments for their patients, which could lead to improved outcomes.

“A better understanding of individual susceptibility to dental disease and variation in treatment outcomes will allow the dental field to move forward,” said Alexandre Vieira, a researcher from the varsity.

“In the future, genetic information may be used to personalize dental treatments and enhance treatment outcomes,” Vieira added.

For the study, the team from America and Brazil analyzed dental records of 807 patients.
Fillings can fail for a variety of reasons, including re-emergence of the initial tooth decay or the filling becoming detached.

The researchers also examined if newer composite resin Dental fillings are as durable as traditional amalgam fillings, which have been in use for more than 150 years but which contain mercury, a toxic metal.

The researchers found that overall, there were no major differences between patients receiving amalgam or composite Dental fillings in terms of filling failure rates. (IANS)

US-North Korea Tensions: Are we on the brink of Destruction?

The US is the only country on Earth, which has committed the gruesome act of using nuclear bombs against humanity. Towards the end of World War II, the then American President Harry S. Truman ordered Japan to surrender, or, “expect a rain of ruin from the air, the like of which has never been seen on this earth.”

Donald Trump and Kim Jong Un
Leaders of United States of America and North Korea. Salil Gewali

Are we on the brink of destruction? Are our precious lives worthless in the hands of two lunatics? Can Mother Earth withstand another holocaust-this time a full-scale destruction? Will sanity prevail in those two demented heads?

Answers to these dreadful questions lie in Washington and Pyongyang. We, like the rest of the inhabitants in the lap of Mother Earth, can only be the dumb spectators. If the dreaded catastrophe befalls, it will be beyond our means to prevent, and beyond our means to survive. Yes, a series of a dreadful missile is being blasted off from the soil of North Korea too frequently. And it is duly matched with the more alarming thunders by the US President Donald Trump. It is frightful to imagine when these two capricious men will be losing their sensible judgment and start acting against the norms of humanity.

The US is the only country on Earth, which has committed the gruesome act of using nuclear bombs against humanity. Towards the end of World War II, the then American President Harry S. Truman ordered Japan to surrender, or, “expect a rain of ruin from the air, the like of which has never been seen on this earth.” He followed up his ultimatum by dropping nuclear bombs on the cities of Hiroshima and Nagasaki on the 6th and the 9th of August, 1945, killing around 200,000 people (Wikipedia).

This gruesome murder of innocent people can be attributed to the American arrogance of power, and affirmation of their destructive capacity. It has been termed as a war crime on humanity and a manifestation of state terrorism. Opponents of this kind of state terrorism argue that the American bombing was immoral and militarily unnecessary. The U.S. still justifies similar horrendous action against any nation, which does not subserve their interests. President Donald Trump’s shocking and outrageous utterances are extensions of the U.S. state behavior. It is frightful to imagine when this vacillating individual will act on his shocking threat of “fire and fury,” as his predecessor did (Article).

On the other hand, why does Kim Jong-un harbor a boundless grudge against the U.S.? Why is he inexhaustibly hostile to the U.S.? Why does Korean People’s Army plan to strike the U.S island of Guam and trigger a grievous conflict? Why does Kim provoke President Donald Trump for the deadliest conflict in history?

Actually, the root cause of this conflict can be traced back to more than half-century. The conflict centers on the Korean War of 1950-53. The 38th parallel divided Korean Peninsula into two in 1948: the South Korea supported by the United States, and the North Korea supported by the then Soviet Union. The infamous Korean War broke out in the year 1950, the South Korea supported by the United States and its allies, and the North Korea supported by the then Soviet Union and China. Kim Il Sung, Kim Jong-un’s grandfather and the then dictator of North Korea fought this gruesome war against America and its allies with the support of the then Soviet Union and China. The War lasted till 1953, injuring or killing an estimated three million Koreans, ten percent of its overall population. This background left Kim Jong-un a wounded dictator. He has been planning a U.S. attack since 2013 (Amstrong). Recently, Pyongyang celebrated the anniversary of the war’s flare-up as “the day of struggle against U.S. imperialism.” (News, Conflict explained).

North Korea is estimated to have 60 nuclear weapons and it has the capability to produce at least six additional nuclear bombs every year. Their intercontinental ballistic missiles could travel about 10,400km putting almost the whole world within its range. North Korea claims it can mount nuclear warheads on its ballistic missiles. In September 2017, North Korea detonated its deadliest hydrogen bomb with an estimated yield of about 100 kilotons. This caused an earthquake measuring 6.3 magnitudes. The tremor was felt in China, about 400km away from the test site. It is worrying to learn that this H-bomb could be 1,000 times more powerful than the nuclear bomb dropped by the U.S. air (article)force on Hiroshima in World War II (News, North Korea testing nuclear weapons).

Experts estimate the casualties of a U.S. – North Korea conflict could be a minimum of one million. A nuclear attack by North Korea can decimate Los Angeles, Chicago, or New York. The U.S.’s anti –ICBM systems may defend the country from a usual test. But, experts opine, on the face of a sudden multiple ICBM’s assaults, the horrifying result could be unpredictable. Of course, the U.S.’s and its allies’ military assets stationed all over the world, including at striking distances could decimate North Korea in seconds. That could not justify the irreparable loss the U.S. would be inflicted upon (News, U.S.- North Korea conflict).

President Donald Trump and Dictator Kim Jong Un must introspect with all seriousness. They must exercise strategic restraint. They must avoid a potential flashpoint. They must think of a world outside their egomania. They must introspect on the devastating consequences of their protracted antagonism.  They must understand military provocations, militant statements. Crossing swords will not solve problems of this magnitude. So, they must listen to the reason and display the right statesmanship which the world’s citizens expect. They must display their compassion and exercise their prudence. They have never been mandated to hurt humankind and to injure the Earth crust.
