Toothpaste fills cavities without drilling

Thursday, February 24, 2005

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.

Massive ice deposits found on Mars

Friday, March 16, 2007

The European Space Agency‘s Mars Express spacecraft has discovered ice deposits in the south pole of Mars that are larger than the state of Texas.

Scientists say that there is enough water in the deposits to cover the entire planet with up to 36 feet of water if the ice was to melt. Some sections of the ice deposits are up to 2.3 – 2.5 miles deep. The ice is composed of carbon dioxide, a little bit of dust, and water (90 percent of the water is estimated to be frozen).

What has caught the attention of the scientists working on the Mars Express project is that this may help reveal whether or not there is any (microbial) life within the ice.

Another perplexing question that scientists are trying to solve is what happened to all the water that produced all the channels on the surface of Mars.

Jeffrey Plaut, who is from NASA’s Jet Propulsion Laboratory in Pasadena, California and who is also leading the study, noted that, “We have this continuing question facing us in studies of Mars, which is: where did all the water go? Even if you took the water in these two (polar) ice caps and added it all up, it’s still not nearly enough to do all of the work that we’ve seen that the water has done across the surface of Mars in its history.”

Currently, only 10 percent of the water is remaining and is located at the poles of Mars. It has been suggested that some of the remaining 90 percent of the water that disappeared could either be underground or could have simply left the atmosphere into space.

Train derailed by collision with semi in Saskatchewan, Canada

Tuesday, March 22, 2005

Twenty-four cars of a west-bound Canada Pacific train were thrown from the tracks after the train collided with a semi tractor-trailer in poor weather and visibility near Regina, Saskatchewan around 11 a.m. Tuesday morning. The driver was rushed to hospital.

The accident took place on a level section of Highway 46 just north of Highway 1, about 25 kilometres east of Regina. The RCMP spokesperson reported the crossing is marked with lights, but weather may have played a role.

“Road conditions were wet and sloppy and it’s foggy,” RCMP Cpl. Brian Jones said to the CBC. The bad weather, including a heavy overnight snowfall, may have contributed to the accident.

Most of the 93 cars in the train were empty bulk transit cars, used for moving agricultural products such as grains. The RCMP report that neither train or truck were transporting any hazardous materials.

Making The Most Of Movers Ct Packing Services

byadmin

Moving is always a stressful time with all that one must begin to prepare for the big day. From the moment, one makes the decision to begin the process of a move, the number of tasks requiring consideration mounts to an overwhelming level. Some people handle moves with enormous skill and ease. However, many individuals and families need assistance in a number of the aspects of moving. A wide range of companies reach out to their customer before, during, and after a move to help coordinate the changing of services even if outside their current service area. However, many people need help with the work required to prepare the house for the move. Because helping movers is their job, many companies can provide services without the emotional attachments along the way. Professional moving and packing companies understand that each item is valuable and treats it as such, offering quick and efficient services.

Movers CT understands the needs of each client varies as much as the items they need to move. While moving boxes and furniture out of the old home and into the new home is an essential part of the business, the company also provides packing services. Packing services are a fantastic option for many individuals and families who are too busy to pack or too overwhelmed to complete the task quickly.

Moving is an emotional experience even if the move is eagerly anticipated. The tasks are daunting when one has to sort through the memories collected with the items in a home, a favorite pair of jeans you cannot part with, baby toys and clothes that no longer fit the teenager you have now, and the dishes, knick-knacks, and books from family members long departed. Each item is valuable and dear to you, and you need to protect the items in the move.

movers CT bring the professional skills and tools to pack all items even the most delicate ones for safe arrival. The individuals and families can spend time going through the items they want to move and those they are ready to part with because someone else is taking care of the packing. While no one can guarantee a stress free moving experience, services are available to address some of the most difficult ones to lighten the burden of moving.

British scholar Tony Judt dies aged 62

Tuesday, August 10, 2010

British historian Tony Judt died Friday of complications from amyotrophic lateral sclerosis (ALS) at the age of 62. Judt was known for his contributions to European history and his controversial position regarding the Israeli–Palestinian conflict.

Judt’s death was announced in a statement from New York University (NYU), where he was a professor. He died in his home in Manhattan, said the school. Judt is survived by his third wife, dance critic Jennifer Homans, and their two children, Nicholas and Daniel. Judt’s first two marriages both ended in a divorce.

Tony Robert Judt, a secular Jew, was born on January 2, 1948 in London, but spent much of his adult life in the United States. The descendant of Marxist Lithuanian rabbis, he was sent to a camp in Israel as a teenager, and became a Zionist. Later, he spoke at a Zionist convention in Paris and worked as a translator for the Israel Defense Forces in 1967, starting with the Six-Day War.

An alumnus of King’s College, he began teaching at NYU as Professor of European studies in 1987. Judt had previously taught at Cambridge, the University of California, and Oxford University.

Judt, also an author, became a Pulitzer Prize finalist for his 2005 book Postwar: A History of Europe Since 1945. The almost 900-page book covers the history of the development of Europe after World War II. He also wrote about topics such as the fall of Marxism and Communism.

In September 2008, Judt was diagnosed with ALS, commonly known as Lou Gehrig’s Disease. One form of motor neurone disease, ALS targets nerve cells and causes a loss of speech and movement abilities. Left paralyzed and unable to breathe without assistance, Judt continued to lecture. Earlier this year, Judt was able to write a group of personal essays for The New York Review of Books, in which he discussed the disease. “In contrast to almost every other serious or deadly disease, one is thus left free to contemplate at leisure and in minimal discomfort the catastrophic progress of one’s own deterioration,” he wrote. In 2009, Judt was the recipient of a special Orwell Prize, given to him for “intelligence, insight and conspicuous courage.”

Judt’s later views on Israel differed from those he had held as a teenager. In 1983, he called Israel a “belligerently intolerant, faith-driven ethno state,” opposing a two-state solution. Earlier this year, he wrote, “most Israelis were not transplanted latter-day agrarian socialists but young, prejudiced urban Jews who differed from their European or American counterparts chiefly in their macho, swaggering self-confidence, and access to armed weapons.” His stance on the topic was the subject of much controversy, even leading to his removal from the editorial committee for The New Republic.

Demonstrators protest Condoleezza Rice’s trip to Australia

Thursday, March 16, 2006

Anti-war demonstrators in Sydney, Australia on Thursday dubbed U.S. Secretary of State Dr Condoleezza Rice a “war criminal” and “murderer.” Two protesters were evicted and five people were arrested during protests against the U.S.-led invasion of Iraq.

Dr Rice, on a three-day trip to Australia, said she understood why people found it hard to be positive about Iraq when all they saw on their television screens was violence.

Soon after Rice began her speech at the University of Sydney’s Conservatorium of Music, two protesters shouted from the rear of the auditorium, “Condoleezza Rice, you are a war criminal,” and “Iraqi blood is on your hands and you cannot wash that blood away.” Standing with their palms towards her, the young man and woman repeated their accusation until security intervened to remove them from the hall.

About 15 minutes into Rice’s address, a third protester appeared at a balcony door, interrupting her speech as she referred to freedom. “What kind of freedom are you talking about? You are a murderer,” said the demonstrator before he was quietly escorted from the hall. “I’m very glad to see that democracy is well and alive here at the university,” she said.

In her speech, Rice sought to justify the U.S. occupation of Iraq, describing Iraqis as now more free. One student asked about abuses committed by U.S. forces at the Abu Ghraib prison in Iraq. She said the abuses had made her “sick to her stomach.” However, she defended Guantanamo Bay, Cuba, where human rights groups say detainees are held in inhumane conditions and in detention flouting international laws.

Before Rice began her speech, about 50 protesters were gathered at the front gates of the Conservatorium. The group were confronted by police on horseback and by police dogs. Police used the horses to charge into the group of activists and push them back, as a police helicopter hovered.

A police spokeswoman said the group was blocking pedestrian access to the building and that police had spent more than 20 minutes warning them to move. The police then moved in and pushed the crowd back 20 metres. Police say five people have been charged with “hindering police in the execution of their duties.”

The “Stop the War Coalition” says Rice is a “war criminal” and is not welcome in Australia. The group’s spokeswoman, Anna Samson, says the protest is one of many planned in the lead-up to the third anniversary of the invasion and occupation of Iraq on March 20.

Paddy Gibson, from the University of Sydney’s Student’s Council, says the protest is in opposition to the Iraq war, and to the use of the University of Sydney’s campus to host Rice, “the most powerful woman in the world,” who they say is a war criminal. “They’re saying, ‘… you’ve got Sydney Uni’s support to stand up and peddle your murderous hate speeches,’ which is what we see it,” he said.

“You’ve got 180,000 people killed, as we said, for no other reason than strategic control of the region’s oil resources. And the anti-Muslim racism that’s been whipped up to justify this war is being felt by Sydney University students,” said Mr Gibson.

Mortgage advisers attempt to collect rent from neighbors after FBI raid in Union City, California

Friday, May 6, 2005

Three months after the FBI raided the offices of the Dorean Group in Union City, California, neighboring companies in the same office park have received letters claiming that rent for the office park should now be paid to the Dorean Group. The owner of the office park, Hanover Properties, insists that they have not sold the park and called the Dorean Group’s claim fraudulent.

The first letter from the Dorean Group, dated May 2nd, 2005, purported to “inform [the tenants] of the change in ownership of the property [the tenants] now occupy,” and asked that “payment of rents be sent” to the principals of the Dorean Group. The letter also included notarized documents authorizing the sale by an alleged agent of the current owner, Hanover Properties, a “Julia Pantibratyuk.”

On the subsequent day, Hanover Properties responded in a letter to the other tenants of the park. They noted that they had not sold the office park to the Dorean Group, but that they had evicted the Dorean Group from the premises on April 26. They added that, “We do not know who Julia Pantbratyuk[sic] is.”

The letters were provided to Wikinews reporter Pingswept by an employee of one of the companies in the office park.

First arrests made in Singapore for possession of New Psychoactive Substances

Sunday, May 4, 2014

The Central Narcotics Bureau (CNB) of Singapore announced yesterday the first arrests made following the listing of New Psychoactive Substances (NPS) as Class A controlled drugs on Thursday, under the First Schedule of the Misuse of Drugs Act. The suspects, two unnamed male Singaporeans, aged 22 and 23, were reportedly arrested at a shopping center in Tampines on Friday evening for possession of synthetic cannabis, also known as “K2”. Authorities recovered 71.7 g of the drug from the suspects.

Under suspicion from the CNB that the 22-year-old suspect was engaged in trafficking of the illegal substance, a further search of his home yielded an additional 22.3 g of synthetic cannabis, raising the total amount of the drug confiscated following the arrests to 94 g.

Synthetic cannabis, listed as an NPS, and known as a “legal high”, is one of a group of designer drugs created to stimulate the effects of controlled drugs including cocaine, Ecstasy, methamphetamine, and heroin. The CNB has linked NPS abuse to symptoms including severe intoxication, hallucinations, paranoia, seizures, cadiovascular problems, renal failure, and death.

Typically having chemical structure very similar but slightly different from controlled drugs, these substances have been illegalized, and their possession, consumption, trafficking, and manufacturing now carry penalties comparable to that of controlled drugs. Last year, under the Fifth Schedule of the Misuse of Drugs Act, designed to study NPSs before their illegalization, they could be confiscated by authorities, but no further penalty would be levied.

The changes to NPS status follow increases over the past year in NPS trafficking and consumption, according to the CNB. Commenting on the move, a spokesperson for the CNB revealed the organization has reported at least thirty NPS seizures in the period from last May through this February. “Thus far,” the spokesperson noted, “synthetic cannabinoids and synthetic cathinones are the two more commonly detected NPS”.

Termed an “alarming new drug problem” by the United Nations Office on Drugs and Crime, its World Drug Report 2013 indicated an increase to 348 NPSs in 2013, up from 251 in 2012. Capitalizing on their legality — which no longer holds in Singapore — NPSs have been known as “legal highs”, “research chemicals”, “plant food”, and “bath salts”.

Commenting on the illegalization of NPSs, Ng Ser Song, the director of the CNB, had this to say. “The drug situation is challenging and the number of repeat drug abusers and young drug abusers remains a concern. With the abuse and trafficking of NPS on the rise, listing these new psychoactive substances as Class A controlled drugs signals our unequivocal stance that these substances are illegal and no different from other controlled drugs.”

Under the recently enacted First Schedule of the Misuse of Drugs Act, if found guilty of drug trafficking, the 22-year-old suspect may be penalized with a minimum of five years in prison and five strokes of the cane. The act also allows the possession or consumption of New Psychoactive Substances to be punished with a maximum of 10 years imprisonment and/or a $20,000 fine.
