A Delta II rocket blasted off from NASA’s Cape Canaveral launch pad today, carrying five satellites designed to investigate the northern lights and the electromagnetic storms that cause them. The launch had been twice delayed due to bad weather, but was eventually performed at 23:00 UTC.

NASA and the Canadian Space Agency have collectively invested $200 million in the mission, known as the THEMIS Project. Through this mission, they hope to develop better techniques to forecast electromagnetic storms, in order to protect communication satellites, power grids, and spacewalking astronauts. Scientists from the University of Alberta and the University of Calgary also helped with the project.

The Sun continuously sends a stream of charged particles, called the solar wind, at the Earth. We are generally protected from the solar wind by the Earth’s magnetosphere. During substorms, however, the magnetosphere gets overloaded by the solar wind and the magnetic field lines stretch until they eventually snap back, energizing and flinging electrically charged particles towards Earth.

Scientists want to find out what snaps in the overloaded magnetosphere to trigger a substorm.

The Transport and General Worker’s Union and Gate Gourmet, the company that laid off 500 workers after workers staged unofficial strike action, will attend further talks held at a conciliation service by the Advisory Conciliation and Arbitration Service (ACAS) on Saturday.

The director of Gate Gourmet, Richard Wells, denied that he was being “heavy-handed” over the dismissals. He insisted that the people affected were spoken to, and given written warnings before they were sacked.

As a result of British Airways (BA) staff at Heathrow joining Gate Gourmet’s staff in the strike action, BA are running 50% of their short-haul flights, and 40% of their long haul flights today from 0600 BST/UTC+1. They are expecting to add more flights to the schedule as the day progresses, so passengers are advised to check the British Airways website.

Analysts said that the disruption may lose BA next to £40m because of the refunds that the company are paying out, loss of flight revenue, and the costs of accommodating passengers in nearby hotels.

Only passengers with confirmed reservations have been allowed to board flights at Heathrow. Barriers have been placed around Terminal 4 to stop people without reservations from joining flights. There are limited catering services on-board the flights.

British Airways advises passengers to telephone +44 (0)800 727 800 or check their website before travelling to the airport. They also said that they would refund customers that had to stay in a hotel on Friday night up to £100.

It is noted by passengers, though, that the advice line can be engaged for long periods, so users of the telephone line need to be patient.

Qantas, Finnair, GB Airways, Sri Lankan Airlines, and British Mediterranean are also affected, as they were serviced by BA’s ground staff. Their telephone numbers are listed below.

• Qantas: +44 (0)870 000 0123
• Sri Lankan Airlines: +44 (0)208 538 2000
• Finnair: +44 (0)8705 997711
• GB Airways: +44 (0)870 850 9850
• British Mediterranean Airlines: +44 (0)870 850 9850

A third call for boycott and second boycott hit the German online travel agency Hotel Reservation Service (HRS) this week. After a recent boycott against HRS in Münsterland, a boycott in Bremerhaven was next and is soon to be followed by the next round in Bremerhaven starting in the middle of March.

Hotels in the city of Bremerhaven already have to pay a new “bed tax” to the state of Bremen of 2.14 euro per person per night, whilst HRS is trying to increase their commission payments for its service from thirteen to fifteen percent. Further criticism of HRS focused on a preferential treatment clause that denied hotels the right to offer better prices through any other booking channel. The European umbrella organization of the catering facilities HOTREC had already criticized this type of clause and similar contract clauses in May 2011 in a position paper.

Piet Rothe, hotel owner and second chairman of the German Hotel and Restaurant Association (DEHOGA) Bremerhaven, explained that in his hotels the boycott hat not decreased bookings, merely shifted their volume to other channels such as, for instance, booking.com, who would only ask for twelve percent commission.

Rüdiger Magowsky, manager of the boarding house in Jaich, confirmed the observation that the volume of bookings had not decreased.Martin Seiffert, manager of the hotel Haverkamp, explained HRS had denied his hotel access to the system because he participated in the boycott. The access has been restored but he is considering participation in the next round of the boycott anyway.

On February 15 the higher regional court of Düsseldorf had ordered HRS in a preliminary injunction not to enforce its preferential treatment clause. Already on February 10 the German Federal Cartel Office had admonished the company for violating §§ 1 and 20 of the German Act against Restraints of Competition.

Meanwhile Markus Luthe, the CEO of the German International Hotel Association (IHA), recommended establishing a “Hotelwiki” as a yellow pages directory of the hotel industry.

Texas Senate Bill 6 requires foster agencies to inquire of adopting couples their sexual preference. This bill has caused distress to many, especially among the gay and lesbian community. Representative Robert Talton claims that compared with children raised by a heterosexual couple, those in same-sex households are much more likely to become homosexual.

Talton has also stated that sexual orientation is a choice for the parents:”If they choose to be homosexual or lesbian, that’s their choice when they turn 18,” he says, regarding the same-sex couples.

Under the bill he proposes, couples who answer ‘same-sex’ or ‘bi-sexual’ on the questionnaire, would not be allowed to adopt or foster children. Children fostered currently to same-sex households would be removed from their foster-parent’s care.

“Some of us believe they would be better off in orphanages than in a homosexual or bisexual households because that’s a learned behavior,” the Republican congressman said.

There are reportedly thousands of children in same-sex households in Texas who would be removed, if this bill is passed.

“It’s very traumatic to remove a child from a stable home,” said Colin Cunliff, field director for the Lesbian/Gay Rights Lobby of Texas. “It’s the whole reason they’re in the foster system, because their prior home wasn’t stable. You’re adding to the instability.”

According to a 2002 report by the American Academy of Pediatrics, children with homosexual parents have the “same advantages and the same expectations for health, adjustment and development as children whose parents are heterosexual.”

A similar law passed in Arkansas was ruled unconstitutional in December.

Voters in California, Florida and Arizona voted on Tuesday to ban gay marriage, bringing about a victory for conservatives on a day which did not bring many conservative wins.

Meanwhile, voters in Colorado, South Dakota and California voted on measures which would have restricted abortion in those states. In Massachusetts and Michigan, voters passed measures that loosen marijuana laws. Finally, in the state of Washington a measure was passed that allows physician-assisted suicide.

The California ballot measure, Proposition 8, overturns the recent June ruling by the California State Supreme Court in the case In re Marriage Cases which reversed a 1977 statute passed by the California State Legislature and a 2000 ballot measure, Proposition 22, which also banned same-sex marriage by defining marriage as between a man and a woman. The wording of Proposition 8 is identical to Proposition 22. It was noted that many of the African-Americans and Latinos who cast their votes for Obama, also voted for the measure. The measure passed at 52% to 48%.

Lesbian comedian Ellen DeGeneres noted, “This morning, when it was clear that Proposition 8 had passed in California, I can’t explain the feeling I had. I was saddened beyond belief. Here we just had a giant step toward equality and then on the very next day, we took a giant step away.”

Singer Melissa Etheridge, who is also a lesbian, stated that she would no longer pay taxes due to the passing of Proposition 8, announcing in a blog post, “Okay, so I am taking that to mean I do not have to pay my state taxes because I am not a full citizen.”

Also in California, voters rejected a measure which would require parental notification for a minor to receive an abortion. The measure was rejected with the same percentage as Proposition 8, 52% to 48%. Meanwhile in Colorado, voters rejected a measure that would define life as beginning at conception. While the measure did not specifically mention abortion it would have required legislators and courts to confront legal rights for fetuses – effectively preventing abortion. The measure was defeated in a wide margin, 73% to 27%

In South Dakota, voters also defeated an anti-abortion measure which would have outlawed abortion in all cases except in the case of rape, incest or if the mother’s health was in serious question. If passed, the law would most likely have been challenged as unconstitutional.

In Michigan, voters approved a measure which legalizes medical marijuana. Meanwhile, in Massachusetts, voters approved a ballot question that decriminalizes possession of small amounts of marijuana in which the possession of an ounce or less would be punishable by a $100 fine. The measure will also require minors under the age 18 to participate in and complete a drug awareness program and do community service. Failure to do so, would net the minor a $1,000 fine.

“Tonight’s results represent a sea change. Voters have spectacularly rejected eight years of the most intense government war on marijuana since the days of ‘Reefer Madness,'” said Rob Kampia, executive director of the Marijuana Policy Project. “The people were ahead of the politicians on this issue; they recognize and want a more sensible approach to our marijuana policy,” said Whitney Taylor, the chair of Committee for Sensible Marijuana Policy, which backed the Massachusetts proposition.

Also, in Massachusetts, voters overwhelmingly, in every single Massachusetts city and town, rejected a ballot measure which would have eliminated the state income tax by 2010, the ballot measure was sponsored by the Committee for Small Government, which is headed up by two libertarians, Michael Cloud, a Libertarian Party candidate for U.S. Senate in 2002 and Carla Howell, Libertarian Party candidate for governor in the 2002 Massachusetts gubernatorial election.

The last time the income tax elimination measure was on the ballot was in 2002, where it was defeated, narrowly by 45.3%. This stunned supporters of the income tax, who mounted a fierce campaign against the measure this time warning Massachusetts residents that repealing the income tax would have drastic effects on the state’s finances, leading to cuts in services, education and local aid.

Finally, voters passed a question which bans dog racing in Massachusetts, which will lead to the closure of Massachusetts’ two greyhound racing tracks, Raynham-Taunton Greyhound Park and Wonderland Greyhound Park.

The campaign against dog racing was headed up by the Committee to Protect Dogs and endorsed by GREY2K USA and the American Society for the Prevention of Cruelty to Animals along with other animal protection organizations who claimed that dog racing was inhumane as the dogs were stuffed into cramped cages and endured injuries. The measure was opposed by the park owners including George Carney who owns the Rayham-Taunton park and Charles Sarkis, a restaurateur who owns Wonderland.

“We did it. We did it for the dogs,” said Carey Thiel, executive director of GREY2K USA. “For 75 years, greyhounds in our state have endured terrible confinement and suffered serious injuries. We’re better than that,” Thiel added.

One campaign supporter, Sandy Bigelow noted, “It means everything. We’ve worked so hard for the dogs and they heard us. It feels so good. Oh, God, it feels so good.”

George Carney said of the results, “It’s not a very pleasant thing right now. Some of these people have been here 40 years. Here’s a company that did nothing wrong, paid their federal taxes on time, paid the town on time. The town is going to be a severe loser, and a lot of people here dedicated their life to the company.”

Both sides used emotionally-charged advertisements, the anti-racing side showing “sad-eyed greyhounds,” while the pro-racing side highlighted the workers who would be out of work when the tracks close.

Both measures must now come before the Massachusetts Governor’s Council for approval.

A ballot initiative approved by voters in the north-western state of Washington will make it the second state to permit physician-assisted suicide. Initiative 1000 follows the ten-year-old example of the Death With Dignity Act of neighboring Oregon, and will allow physicians to prescribe a lethal dose of medication for a terminally ill patient to administer themselves. It was approved by a margin of 16%, and the ‘Yes’ campaign outspent the ‘No’ campaign by more than three-to-one. The law comes into effect in 2009.

A new historic physics record has been set by scientists for exceedingly small writing, opening a new door to computing‘s future. Stanford University physicists have claimed to have written the letters “SU” at sub-atomic size.

Graduate students Christopher Moon, Laila Mattos, Brian Foster and Gabriel Zeltzer, under the direction of assistant professor of physics Hari Manoharan, have produced the world’s smallest lettering, which is approximately 1.5 nanometres tall, using a molecular projector, called Scanning Tunneling Microscope (STM) to push individual carbon monoxide molecules on a copper or silver sheet surface, based on interference of electron energy states.

A nanometre (Greek: ?????, nanos, dwarf; ?????, metr?, count) is a unit of length in the metric system, equal to one billionth of a metre (i.e., 10^-9 m or one millionth of a millimetre), and also equals ten Ångström, an internationally recognized non-SI unit of length. It is often associated with the field of nanotechnology.

“We miniaturised their size so drastically that we ended up with the smallest writing in history,” said Manoharan. “S” and “U,” the two letters in honor of their employer have been reduced so tiny in nanoimprint that if used to print out 32 volumes of an Encyclopedia, 2,000 times, the contents would easily fit on a pinhead.

In the world of downsizing, nanoscribes Manoharan and Moon have proven that information, if reduced in size smaller than an atom, can be stored in more compact form than previously thought. In computing jargon, small sizing results to greater speed and better computer data storage.

“Writing really small has a long history. We wondered: What are the limits? How far can you go? Because materials are made of atoms, it was always believed that if you continue scaling down, you’d end up at that fundamental limit. You’d hit a wall,” said Manoharan.

In writing the letters, the Stanford team utilized an electron‘s unique feature of “pinball table for electrons” — its ability to bounce between different quantum states. In the vibration-proof basement lab of Stanford’s Varian Physics Building, the physicists used a Scanning tunneling microscope in encoding the “S” and “U” within the patterns formed by the electron’s activity, called wave function, arranging carbon monoxide molecules in a very specific pattern on a copper or silver sheet surface.

“Imagine [the copper as] a very shallow pool of water into which we put some rocks [the carbon monoxide molecules]. The water waves scatter and interfere off the rocks, making well defined standing wave patterns,” Manoharan noted. If the “rocks” are placed just right, then the shapes of the waves will form any letters in the alphabet, the researchers said. They used the quantum properties of electrons, rather than photons, as their source of illumination.

According to the study, the atoms were ordered in a circular fashion, with a hole in the middle. A flow of electrons was thereafter fired at the copper support, which resulted into a ripple effect in between the existing atoms. These were pushed aside, and a holographic projection of the letters “SU” became visible in the space between them. “What we did is show that the atom is not the limit — that you can go below that,” Manoharan said.

“It’s difficult to properly express the size of their stacked S and U, but the equivalent would be 0.3 nanometres. This is sufficiently small that you could copy out the Encyclopaedia Britannica on the head of a pin not just once, but thousands of times over,” Manoharan and his nanohologram collaborator Christopher Moon explained.

The team has also shown the salient features of the holographic principle, a property of quantum gravity theories which resolves the black hole information paradox within string theory. They stacked “S” and the “U” – two layers, or pages, of information — within the hologram.

The team stressed their discovery was concentrating electrons in space, in essence, a wire, hoping such a structure could be used to wire together a super-fast quantum computer in the future. In essence, “these electron patterns can act as holograms, that pack information into subatomic spaces, which could one day lead to unlimited information storage,” the study states.

The “Conclusion” of the Stanford article goes as follows:

The team is not the first to design or print small letters, as attempts have been made since as early as 1960. In December 1959, Nobel Prize-winning physicist Richard Feynman, who delivered his now-legendary lecture entitled “There’s Plenty of Room at the Bottom,” promised new opportunities for those who “thought small.”

Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as work in particle physics (he proposed the parton model).

Feynman offered two challenges at the annual meeting of the American Physical Society, held that year in Caltech, offering a $1000 prize to the first person to solve each of them. Both challenges involved nanotechnology, and the first prize was won by William McLellan, who solved the first. The first problem required someone to build a working electric motor that would fit inside a cube ¹/₆₄ inches on each side. McLellan achieved this feat by November 1960 with his 250-microgram 2000-rpm motor consisting of 13 separate parts.

In 1985, the prize for the second challenge was claimed by Stanford Tom Newman, who, working with electrical engineering professor Fabian Pease, used electron lithography. He wrote or engraved the first page of Charles Dickens’ A Tale of Two Cities, at the required scale, on the head of a pin, with a beam of electrons. The main problem he had before he could claim the prize was finding the text after he had written it; the head of the pin was a huge empty space compared with the text inscribed on it. Such small print could only be read with an electron microscope.

In 1989, however, Stanford lost its record, when Donald Eigler and Erhard Schweizer, scientists at IBM’s Almaden Research Center in San Jose were the first to position or manipulate 35 individual atoms of xenon one at a time to form the letters I, B and M using a STM. The atoms were pushed on the surface of the nickel to create letters 5nm tall.

In 1991, Japanese researchers managed to chisel 1.5 nm-tall characters onto a molybdenum disulphide crystal, using the same STM method. Hitachi, at that time, set the record for the smallest microscopic calligraphy ever designed. The Stanford effort failed to surpass the feat, but it, however, introduced a novel technique. Having equaled Hitachi’s record, the Stanford team went a step further. They used a holographic variation on the IBM technique, for instead of fixing the letters onto a support, the new method created them holographically.

In the scientific breakthrough, the Stanford team has now claimed they have written the smallest letters ever – assembled from subatomic-sized bits as small as 0.3 nanometers, or roughly one third of a billionth of a meter. The new super-mini letters created are 40 times smaller than the original effort and more than four times smaller than the IBM initials, states the paper Quantum holographic encoding in a two-dimensional electron gas, published online in the journal Nature Nanotechnology. The new sub-atomic size letters are around a third of the size of the atomic ones created by Eigler and Schweizer at IBM.

A subatomic particle is an elementary or composite particle smaller than an atom. Particle physics and nuclear physics are concerned with the study of these particles, their interactions, and non-atomic matter. Subatomic particles include the atomic constituents electrons, protons, and neutrons. Protons and neutrons are composite particles, consisting of quarks.

“Everyone can look around and see the growing amount of information we deal with on a daily basis. All that knowledge is out there. For society to move forward, we need a better way to process it, and store it more densely,” Manoharan said. “Although these projections are stable — they’ll last as long as none of the carbon dioxide molecules move — this technique is unlikely to revolutionize storage, as it’s currently a bit too challenging to determine and create the appropriate pattern of molecules to create a desired hologram,” the authors cautioned. Nevertheless, they suggest that “the practical limits of both the technique and the data density it enables merit further research.”

In 2000, it was Hari Manoharan, Christopher Lutz and Donald Eigler who first experimentally observed quantum mirage at the IBM Almaden Research Center in San Jose, California. In physics, a quantum mirage is a peculiar result in quantum chaos. Their study in a paper published in Nature, states they demonstrated that the Kondo resonance signature of a magnetic adatom located at one focus of an elliptically shaped quantum corral could be projected to, and made large at the other focus of the corral.

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.

Saturday, January 29, 2005With just days to go before Sunday’s historic poll to choose a new government in Iraq, UN Secretary General Kofi Annan has invited the people of Iraq to exercise their democratic rights.

The poll, the first free elections in a generation, faces disruption from insurgents who are totally opposed to democracy. Annan warned them not to interfere and promised continuing help from the UN for the country in the future.

Annan made his appeal in a pre-recorded message, broadcast on TV inside Iraq. “Elections are the best way to determine any country’s future; please exercise your democratic rights on Sunday,” he said. “Whatever your feelings about how the country reached this point, this election offers an opportunity to move away from violence and uncertainty toward peace and representative government.”

The UN has been providing advice and technical help to the Independent Electoral Commission of Iraq (IECI), as well as $100m funding for the poll and co-ordination of international assistance. A team of 40 experts has overseen the delivery of three million tonnes of election materials and helped the IECI and Iraqi officials prepare and maintain the voters register.

2008 Taipei International Cycle Show (Taipei Cycle) & Taipei International Sporting Goods Show (TaiSPO) not only did a best reunion with conjunctions of the launch of Taipei World Trade Center Nangang Exhibition and the concurrent cycling race of 2008 Tour de Taiwan but also provide opportunities and benefits for sporting goods, bicycle, and athlete sports industries to establish the basis of the sourcing center in Asia and notabilities on the international cycling race.

Although the Taipei cycle was split from the TaiSPO since 1988, but the trends of sporting good industry in Taiwan changed rapidly and multiply because of modern people’s lifestyles and habits. After the “TaiSPO Innovation Award” was established since 2005, the fitness and leisure industries became popular stars as several international buyers respected on lifestyle and health.

For example, some participants participated Taipei Cycle and TaiSPO with different product lines to do several marketing on bicycle and fitness equipments, this also echoed the “Three New Movements” proposed by Giant Co., Ltd. to make a simple bicycle with multiple applications and functions. As of those facts above, Wikinews Journalist Rico Shen interviewed Ideal Bike Corporation and Gary Silva, designer of “3G Steeper” to find out the possibilities on the optimizations between two elements, fitness and bicycle.
