A paste containing synthetic tooth enamel can seal small cavities without drilling. Kazue Yamagishi and colleagues at the FAP Dental Institute in Tokyo say that the paste can repair small cavities in 15 minutes.

Currently, fillers don’t stick to such small cavities so dentists must drill bigger holes. Hydroxyapatite crystals, of which natural enamel is made, bond with teeth to repair tiny areas of damage.

Yamagishi and colleagues have tested their paste on a lower premolar tooth that showed early signs of decay. They found that the synthetic enamel merged with the natural enamel. The synthetic enamel also appears to make teeth stronger which will improve resistance to future decay. As with drilling, however, there is still the potential for pain: The paste is strongly acidic to encourage crystal growth and causes inflammation if it touches the gums.

The paste is reported in the journal Nature.

On Tuesday, the press and members of the National Turkey Federation gathered in large numbers at the White House’s Rose Garden in the United States to witness an annual Thanksgiving tradition in the U.S., a presidential pardon of two Thanksgiving turkeys.

Every year, a U.S. President gives a pardon to two turkeys, saving them from being put on a dinner table somewhere in America. This year, President George W. Bush pardoned two turkeys named May and Flower, who were both chosen for the pardon by the citizens of the U.S.

“Each of you is taking part in a tradition that goes back to the days of Harry Truman. And to paraphrase Harry today, we have a message for our two feathered friends: You cannot take the heat — and you’re definitely going to stay out of the kitchen. I thank everybody who voted online to choose the names for our guests of honor. And I’m pleased to announce the winning names [May and Flower]. [These names are] certainly better than the names the vice president suggested, which was Lunch and Dinner,” Bush said jokingly.

After receiving the pardons, the turkeys got a special ride in a three-car motorcade to Dulles Airport, which included an array of lights, sirens and police motorcycles. From there, both turkeys were flown to Orlando, Florida on a plane dubbed United Turkey One where they were the Grand Marshalls for today’s Thanksgiving Day parade in Walt Disney World. Both turkeys received a welcome which included a red carpet, and free passes to the park.

“So now I have a task, and that is to grant a full presidential pardon to May and Flower. They’ll be shortly flown to Disney World, where they will serve as Honorary Grand Marshals for the Thanksgiving Day Parade. I hope that honor doesn’t go to their head. May they live the rest of their lives in blissful gobbling. And may all Americans enjoy a holiday full of love and peace. God bless you all,” added Bush.

The U.S. House Energy and Commerce Committee passed an amendment on Wednesday to extend daylight saving time by two months. The bipartisan measure is sponsored by Representative Fred Upton, Republican of Michigan, and Representative Ed Markey, Democrat of Massachusetts.

“The more daylight we have, the less electricity we use,” Representative Ed Markey said. Markey also supported the measure by pointing out the business benefits. “There’s more economic activity, because people feel they can walk around safely,” he said.

“Extending daylight-saving time makes sense, especially with skyrocketing energy costs,” Rep. Fred Upton said.

The bill extends daylight saving time to begin on the first Sunday in March and to end on the last Sunday in November. Daylight saving time currently begins on the first Sunday in April and ends on the first Sunday in October.

The U.S. Department of Transportation estimates that extending daylight saving time would save 10,000 barrels of oil per day. The United States consumes approximately 20 million barrels of oil per day.

The House is planning to approve the energy bill to which the amendment was attached in several weeks. Several other amendments to the bill are still being debated.

Eight Burmese boat people, who arrived off Western Australia‘s Ashmore Reef last week, say they wish to claim refugee status. The group of 8 men, aged between 24 and 40, are being held in detention on Christmas Island by the Australian Federal Government. They will be sent to Nauru after identity interviews and medical checks are completed.

According to The Age newspaper, the men are from a refugee camp on the Thai-Burmese border, and may be from the Karen tribe, who are battling Burma’s brutal military Government. Karen rebels have been at war with the central Government for 57 years.

An Immigration department spokesman confirmed that the eight men claimed to be from Burma. Two of the men have contacted immigration lawyers, seeking assistance with asylum claims. David Manne, from Melbourne-based Refugee and Immigration Legal Centre, said the other six were likely to do the same. “There’s a very strong likelihood that they are genuine refugees,” he said.

The men were first spotted by the Australian Customs Service at Ashmore Reef, 610km north of Broome, WA on August 13. They were sent by Navy vessel to Christmas Island – 2,400 km northwest of Perth, WA. The men have been held since Friday as part of the Howard Government’s Pacific Solution to keep asylum seekers out of the country.

In 2005, the Department of Immigration began construction of an Immigration Reception and Processing Centre on Christmas Island, due for completion late in 2006. The facility is estimated to cost $210 million, and will contain 800 beds.

The news of the boat people’s arrival became public last week as Prime Minister John Howard scrapped controversial new migration laws. The proposed laws would have excised the Australian mainland for immigration purposes.

Ashmore Reef, already excised from Australia’s migration zone, means the men have no legal entitlement to be brought to Australia for processing. They have no access to the Australian court system to argue their claims or contest the rulings of the Immigration Department.

Mr Manne said he was concerned that the circumstances of the men’s confinement could hamper their attempts to communicate with lawyers. He said the Burmese men should be afforded the same rights as the West Papuans or Vietnamese asylum-seekers who recently made it to Australian shores. “It’s absolutely crucial these people be given a fair go, so that they can actually speak with us properly about the issues,” he said. Mr Manne says he has made several requests of the Department of Immigration in Canberra.

“They’re asylum seekers… they believe that they’d be persecuted if sent to Burma, and we have agreed to act on their behalf.” He was unable to say whether the group was dropped off by people smugglers, as Immigration Minister Senator Amanda Vanstone claims.

“What we do know is they’re seeking refugee status, that is, protection from brutal human rights abuse,” he said. The Burmese regime has recently waged an aggressive attack on Karen insurgents – forcing thousands of villagers to hide in the jungle or seek refuge in Thailand. There are 140,000 refugees in seven camps along the Thai-Burma border.

Australian Greens Senator Kerry Nettle says the government must allow the Burmese group to be brought to Australia to process the asylum-seeker’s claims. “The government needs to ensure that all asylum seekers are offered legal support,” she said. “The best way to ensure the Burmese asylum seekers have full access to their lawyer is to bring them to Australia while their asylum claims are assessed.”

Meanwhile the near-bankrupt Nauru Government has urged Australia to “speed up asylum seeker processing” in their country. Nauru says Australia is taking far too long to process asylum seekers. Currently two refugees remain on Nauru – both Iraqi men. The men have been held in detention on the remote tiny island for five years.

According to The Age, the Nauru Government has approved a plan to impose financial penalties on Australia if asylum seekers are forced to languish on the near-bankrupt island. The report says if they have not been processed and either returned or resettled within three months, their visas will have to be renewed each month, with the cost increasing by $500 for each renewal.

Nauru’s Foreign Minister David Adeang raised serious concerns about the mental state of the detainees. He says Muhammad Faisal’s condition worsened sharply after he was re-interviewed by ASIO. Mr Adeang has asked for the Government to evacuate the Mr Faisal immediately, he says he is also concerned about the mental health of the other Iraqi man left on Nauru. The Australian Government claims advice from ASIO that the man may be a “security threat.”

Nauru is the world’s smallest island nation, covering just 21 km². Since 2001 it has accepted aid from the Australian government. In exchange for this aid, Nauru houses an ‘offshore’ detention centre for Australia.

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 robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.
