A recent study by the United States Geological Survey (USGS) shows that the oil and gas industry are creating earthquakes. New information from the Midwest region of the United States points out that these man-made earthquakes are happening more frequently than expected. While more frequent earthquakes are less of a problem for regions like the Midwest, a geology professor from the University of Southern Indiana, Dr. Paul K. Doss, believes the disposal of wastewater from the hydraulic fracturing (or “fracking”) process used in extracting oil and gas has the possibility to pose potential problems for groundwater.

“We are taking this fluid that has a whole host of chemicals in it that are useful for fracking and putting it back into the Earth,” Doss said. “From a purely seismic perspective these are not big earthquakes that are going to cause damage or initiate, as far as we know, any larger kinds of earthquakes activity for Midwest. [The issue] is a water quality issue in terms of the ground water resources that we use.”

Hydraulic fracturing, or fracking, is a technique used by the oil and gas industries which inject highly pressurized water down into the Earth’s crust to break rock and extract natural gas. Most of the fluids used for fracking are proprietary, so information about what chemicals are used in the various fluids are unknown to the public and to create a competitive edge.

Last Monday four researchers from the University of New Brunswick released an editorial that sheds light on the potential risks that the current wastewater disposal system could have on the province’s water resources. The researchers share the concern that Dr. Doss has and have come out to say that they believe fracking should be stopped in the province until there is an environ­mentally safe way to dispose the waste wastewater.

“If groundwater becomes contamin­ated, it takes years to decades to try to clean up an aquifer system,” University of New Brunswick professor Tom Al said.

While the USGS group which conducted the study says it is unclear how the earthquake rates may be related to oil and gas production, they’ve made the correlation between the disposal of wastewater used in fracking and the recent upsurge in earthquakes. Because of the recent information surfacing that shows this connection between the disposal process and earthquakes, individual states in the United States are now passing laws regarding disposal wells.

“The problem is that we have never, as a human society, engineered a hole to go four miles down in the Earth’s crust that we have complete confidence that it won’t leak,” Doss said. “A perfect case-in-point is the Gulf of Mexico oil spill in 2010, that oil was being drilled at 18,000 feet but leaked at the surface. And that’s the concern because there’s no assurance that some of these unknown chemical cocktails won’t escape before it gets down to where they are trying to get rid of them.”

It was said in the study released by the New Brunswick University professors that if fracking wastewater would contaminate groundwater, that current conventional water treatment would not be sufficient enough to remove the high concentration of chemicals used in fracking. The researchers did find that the wastewater could be recycled, can also be disposed of at proper sites or even pumped further underground into saline aquifers.

The New Brunswick professors have come to the conclusion that current fracking methods used by companies, which use the water, should be replaced with carbon diox­ide or liquefied propane gas.

“You eliminate all the water-related issues that we’re raising, and that peo­ple have raised in general across North America,” Al said.

In New Brunswick liquefied propane gas has been used successfully in fracking some wells, but according to water specialist with the province’s Natural Resources De­partment Annie Daigle, it may not be the go-to solution for New Brunswick due its geological makeup.

“It has been used successfully by Corridor Resources here in New Bruns­wick for lower volume hydraulic frac­turing operations, but it is still a fairly new technology,” Daigle said.

The United States Environmental Protection Agency (EPA) is working with U.S. states to come up with guidelines to manage seismic risks due to wastewater. Under the Safe Drinking Water Act, the EPA is the organization that also deals with the policies for wells.

Oil wells, which are under regulation, pump out salt water known as brine, and after brine is pumped out of the ground it’s disposed of by being pumped back into the ground. The difference between pumping brine and the high pressurized fracking fluid back in the ground is the volume that it is disposed of.

“Brine has never caused this kind of earthquake activity,” Doss said. “[The whole oil and gas industry] has developed around the removal of natural gas by fracking techniques and has outpaced regulatory development. The regulation is tied to the ‘the run-of-the-mill’ disposal of waste, in other words the rush to produce this gas has occurred before regulatory agencies have had the opportunity to respond.”

According to the USGS study, the increase in injecting wastewater into the ground may explain the sixfold increase of earthquakes in the central part of the United States from 2000 – 2011. USGS researchers also found that in decades prior to 2000 seismic events that happened in the midsection of the U.S. averaged 21 annually, in 2009 it spiked to 50 and in 2011 seismic events hit 134.

“The incredible volumes and intense disposal of fracking fluids in concentrated areas is what’s new,” Doss said. “There is not a body of regulation in place to manage the how these fluids are disposed of.”

The study by the USGS was presented at the annual meeting of the Seismological Society of America on April 18, 2012.

A team of eight transplant surgeons in Cleveland Clinic in Ohio, USA, led by reconstructive surgeon Dr. Maria Siemionow, age 58, have successfully performed the first almost total face transplant in the US, and the fourth globally, on a woman so horribly disfigured due to trauma, that cost her an eye. Two weeks ago Dr. Siemionow, in a 23-hour marathon surgery, replaced 80 percent of her face, by transplanting or grafting bone, nerve, blood vessels, muscles and skin harvested from a female donor’s cadaver.

The Clinic surgeons, in Wednesday’s news conference, described the details of the transplant but upon request, the team did not publish her name, age and cause of injury nor the donor’s identity. The patient’s family desired the reason for her transplant to remain confidential. The Los Angeles Times reported that the patient “had no upper jaw, nose, cheeks or lower eyelids and was unable to eat, talk, smile, smell or breathe on her own.” The clinic’s dermatology and plastic surgery chair, Francis Papay, described the nine hours phase of the procedure: “We transferred the skin, all the facial muscles in the upper face and mid-face, the upper lip, all of the nose, most of the sinuses around the nose, the upper jaw including the teeth, the facial nerve.” Thereafter, another team spent three hours sewing the woman’s blood vessels to that of the donor’s face to restore blood circulation, making the graft a success.

The New York Times reported that “three partial face transplants have been performed since 2005, two in France and one in China, all using facial tissue from a dead donor with permission from their families.” “Only the forehead, upper eyelids, lower lip, lower teeth and jaw are hers, the rest of her face comes from a cadaver; she could not eat on her own or breathe without a hole in her windpipe. About 77 square inches of tissue were transplanted from the donor,” it further described the details of the medical marvel. The patient, however, must take lifetime immunosuppressive drugs, also called antirejection drugs, which do not guarantee success. The transplant team said that in case of failure, it would replace the part with a skin graft taken from her own body.

Dr. Bohdan Pomahac, a Brigham and Women’s Hospital surgeon praised the recent medical development. “There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Leading bioethicist Arthur Caplan of the University of Pennsylvania withheld judgment on the Cleveland transplant amid grave concerns on the post-operation results. “The biggest ethical problem is dealing with failure — if your face rejects. It would be a living hell. If your face is falling off and you can’t eat and you can’t breathe and you’re suffering in a terrible manner that can’t be reversed, you need to put on the table assistance in dying. There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Dr Alex Clarke, of the Royal Free Hospital had praised the Clinic for its contribution to medicine. “It is a real step forward for people who have severe disfigurement and this operation has been done by a team who have really prepared and worked towards this for a number of years. These transplants have proven that the technical difficulties can be overcome and psychologically the patients are doing well. They have all have reacted positively and have begun to do things they were not able to before. All the things people thought were barriers to this kind of operations have been overcome,” she said.

The first partial face transplant surgery on a living human was performed on Isabelle Dinoire on November 27 2005, when she was 38, by Professor Bernard Devauchelle, assisted by Professor Jean-Michel Dubernard in Amiens, France. Her Labrador dog mauled her in May 2005. A triangle of face tissue including the nose and mouth was taken from a brain-dead female donor and grafted onto the patient. Scientists elsewhere have performed scalp and ear transplants. However, the claim is the first for a mouth and nose transplant. Experts say the mouth and nose are the most difficult parts of the face to transplant.

In 2004, the same Cleveland Clinic, became the first institution to approve this surgery and test it on cadavers. In October 2006, surgeon Peter Butler at London‘s Royal Free Hospital in the UK was given permission by the NHS ethics board to carry out a full face transplant. His team will select four adult patients (children cannot be selected due to concerns over consent), with operations being carried out at six month intervals. In March 2008, the treatment of 30-year-old neurofibromatosis victim Pascal Coler of France ended after having received what his doctors call the worlds first successful full face transplant.

Ethical concerns, psychological impact, problems relating to immunosuppression and consequences of technical failure have prevented teams from performing face transplant operations in the past, even though it has been technically possible to carry out such procedures for years.

Mr Iain Hutchison, of Barts and the London Hospital, warned of several problems with face transplants, such as blood vessels in the donated tissue clotting and immunosuppressants failing or increasing the patient’s risk of cancer. He also pointed out ethical issues with the fact that the procedure requires a “beating heart donor”. The transplant is carried out while the donor is brain dead, but still alive by use of a ventilator.

According to Stephen Wigmore, chair of British Transplantation Society’s ethics committee, it is unknown to what extent facial expressions will function in the long term. He said that it is not certain whether a patient could be left worse off in the case of a face transplant failing.

Mr Michael Earley, a member of the Royal College of Surgeon‘s facial transplantation working party, commented that if successful, the transplant would be “a major breakthrough in facial reconstruction” and “a major step forward for the facially disfigured.”

In Wednesday’s conference, Siemionow said “we know that there are so many patients there in their homes where they are hiding from society because they are afraid to walk to the grocery stores, they are afraid to go the the street.” “Our patient was called names and was humiliated. We very much hope that for this very special group of patients there is a hope that someday they will be able to go comfortably from their houses and enjoy the things we take for granted,” she added.

In response to the medical breakthrough, a British medical group led by Royal Free Hospital’s lead surgeon Dr Peter Butler, said they will finish the world’s first full face transplant within a year. “We hope to make an announcement about a full-face operation in the next 12 months. This latest operation shows how facial transplantation can help a particular group of the most severely facially injured people. These are people who would otherwise live a terrible twilight life, shut away from public gaze,” he said.

According to media reports, a Colombian air force AC-47 (registration FAC1670) spy plane carrying five people has crashed near the Colombian city of La Dorada, in the department of Caldas.

All on board the plane are believed to have been killed, according to Colombia Reports. Among the dead, according to Monsters and Critics, are two technicians, a major and two second lieutenants. ABS-CBN News reports that the dead included three high ranking officials and two lower ranking ones.

Jorge Ballesteros, a Colombian air force official, says that the plane took off from an air force base in the city of Puerto Salgar and was on an exercise mission when it crashed. He also states that although it was on a training exercise, the plane was carrying bombs and machine guns.

A military team has been dispatched to the area to investigate the incident, but they have already put the blame on mechanical failure. Ballestero noted that investigators have ruled out a rebel attack and terrorism as possible causes.

AC-47’s have been used by the Colombian air force for nearly 20 years, most of which were donated from the United States. They were provided to the country in an attempt to fight the illegal drug market and to defend citizens and the military against rebel attacks. They are also used to gather intelligence and come equipped with a state-of-the-art communications system, radar and infrared detection systems.

Wikinews reporter Iain Macdonald has performed an interview with Dr Isabella Margara, a London-based member of the Communist Party of Greece (KKE). In the interview Margara sets out the communist response to current events in Greece as well as discussing the viability of a communist economy for the nation. She also hit back at Petros Tzomakas, a member of another Greek far-left party which criticised KKE in a previous interview.

The interview comes amid tensions in cash-strapped Greece, where the government is introducing controversial austerity measures to try to ease the nation’s debt-problem. An international rescue package has been prepared by European Union member states and the International Monetary Fund – should Greece require a bailout; protests have been held against government attempts to manage the economic situation.

Microsoft announced on Thursday they are partnering with KIND Financial to help governments track the production and distribution of legal marijuana. Kind Financial, a California-based start-up company, began selling its Agrisoft Seed to Sale software three years ago. Microsoft is admitting Kind’s software on the Government portion of its Azure cloud service.

Although Kind Financial CEO David Dinenberg stressed to The Guardian they “absolutely do not touch the plant”, his company does business with growers and distributors of marijuana, as well as the governments that regulate it. State law in twenty-five US states — but not US federal law — has legalized marijuana, whether medicinally or for recreational use. Kimberly Nelson, Microsoft executive director of state and local government solutions, said they expect significant demand for technology to help states make sure cannabis distribution within their state is done according to their laws.

Kind also provides kiosks similar to automated tellers (ATMs) to facilitate marijuana transactions in dispensaries. The distribution of marijuana is often done only with cash or through machines like the ones Kind offers since many banks in the United States shy away from the marijuana industry entirely. Microsoft is not interacting with this part of Kind’s operations, however.

Microsoft and Kind will apply for contracts with state governments for their software. Currently, they have applied to Puerto Rico, a US territory, where medical marijuana has recently been made legal. BioTrackTHC, a company similar to Kind Financial, already has contracts with Washington, New Mexico, and Illinois.

Dinenberg said his company’s partnership with Microsoft is a major step in advancing the legitimacy of cannabis-related businesses.

Ricardo Serran Lobo is a Brazilian blogger who writes about his famous neighbor, the politician Roberto Jefferson, head of the Brazilian Labor Party in the Brazilian Congress of Deputies. Jefferson has become a major figure in the ongoing Brazilian mensalão scandal revolving around corruption and bribery.

Vizinho do Jefferson [1] quickly became very popular among Brazilians, describing the routine of Jefferson, while providing information about politics and fresh news about the scandal. Lobo’s blog got third place in the Best Of Blogs contest run by Deutsche Welle International.

Lobo gets an intimate look at the center of Brazilian politics by living in Brasilia, near residences of parliamentarians (including Roberto Jefferson), public buildings and the Brazilian Chamber of Deputies. Or, as he says in his blog: “near the eye of the hurricane,” a reference to the recent political crisis.

At first, Lobo began describing the daily activities of his famous neighbor deputy Roberto Jefferson. As the crisis moved on, he began to describe the political events regarding it. His writings evolved to not only what is going on with Jefferson, but what is going on in Brazilian Congress, and has interviewed politicians, including Roberto Jefferson himself.

The blog tries to be informative, with a lot of humour (common with Brazilians), and some protests against the bad habits of Brazilian politics in general.

Jefferson’s neighbor, the blog, is an example of citizen journalism and it shows that ordinary people can compete with professional media.
