A 1965 Volkswagen minibus that was stolen in 1974 has been recovered by customs agents in Los Angeles. The vintage minibus was in pristine condition, valued at $25,000, and was found during a routine inspection of a shipping container scheduled for departure to The Netherlands. A routine computer database search on its vehicle identification number flagged it as having been stolen from a vehicle upholstery shop in Spokane, Washington on July 12, 1974. A custom restoration business in Arizona was attempting to deliver it to overseas clients last month when authorities intercepted the vehicle.

The theft appeared on the National Insurance Crime Bureau database, which is used by border authorities and contains all stolen vehicle records. Most police databases remove unsolved vehicle thefts after five years.

The California Highway Patrol does not suspect the restorer of wrongdoing, according to investigating officer Mike Maleta. Possession of the vehicle apparently changed several times. Police in Spokane have not yet located the rightful owner, whose identity has not been released to the press. Maleta hopes that a trail of registration documents and interviews will uncover the thief.

The Allstate insurance company paid $2500 shortly after the theft occurred and wants to take possession of the vintage minibus. Allstate spokeswoman Megan Brunet expects that after the necessary paperwork is processed the firm will sell it at auction.

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.

The UK Government has stated that children in Britain will no longer be required to take compulsory, externally marked tests at the age of fourteen.

The change takes effect immediately, meaning that children who were due to take the test this year no longer have to do so.

Secretary of State for Children, Schools and Families Ed Balls yesterday announced his plans to radically change the UK testing system, in parliament.

Currently, almost ten million tests are sat each year by British pupils. This change is expected to cut the number of tests taken in half, according to The Guardian.

The tests for seven and eleven year olds are not being abolished. A review group is being set up, however, to research the effect of these tests on eleven-year-olds.

Instead of league tables showing test results, the government will produce report cards for secondary schools. According to Ed Balls, the results from GCSEs will be adequate to judge the performance of schools by their test results.

The decision to abolish the tests for fourteen year olds came as a result of a situation earlier this year, when there were long delays with the delivery of test results to students of this age.

According to Christine Blower, acting general secretary of the National Union of Teachers, the government is admitting that the previous test system failed by making this move.

“For too long English, mathematics and science teachers in secondary schools have found themselves skewing everything to enable their pupils to jump through a series of unnecessary hoops,” she claimed, while Chris Keates, general secretary of the National Association of Schoolmasters Union of Women Teachers, said that “the sound of a deep collective sigh of relief will emanate from secondary schools across the country.”

Both major UK opposition parties welcomed this move. Conservative Shadow Secretary of State for Children Michael Gove stated that his party have “argued for fewer national tests and more rigor and we want to work constructively to improve the assessment and qualifications regime.”

David Laws, Shadow Secretary of State for Children for the Liberal Democrats, said that “the Sats tests taken by 14-year-olds are not only a waste of time but have been highly unreliable over the last few years.”

The median house price in the United States plunged 6.5% in May to $217,000. In February of 2005, the median price of a home was $237,300.

The Economist newspaper said in its June 16th issue; “In other words, it looks like the biggest bubble in history.” by way of reference to what is happening with housing prices in the USA and much of Europe.

Japan provides an example of how a boom can turn to bust. Property prices have dropped for 14 years in a row (40% from their peak in 1991); and yet, the rise in prices in Japan during the decade before 1991 was less than the increase over the past ten years in most of today’s “housing boom” countries.

The total value of residential property rose by more than $30 trillion over the past five years in developed economies, an increase equivalent to 100% of the combined GDPs of those countries. This increase dwarfs all previous house-price booms and is greater than the global stockmarket bubble in the late 1990s. Much of the recent housing activity is being driven by speculative demand. The National Association of Realtors (NAR) reported that 23% of all American houses bought in 2004 were for investment, not for owners to live in. Another 13% were bought as second homes. NAR also found that 42% of all first-time buyers made no down-payment on their home purchase last year.

Many investors are buying solely because they think prices will keep rising, which is a warning sign of a financial bubble. In Miami, Florida, as many as half of the original buyers resell new apartments even before they are built, and properties can change hands two or three times before somebody finally moves in.

Britain’s Royal Institution of Chartered Surveyors (RICS) reported prices have been falling for ten consecutive months. Forty nine percent of their surveyors reported falling prices in May. This was the weakest report since 1992 during Britain’s previous house-price bust.

The president of Egypt has suffered a “devastating blow” after the country’s army announced they would not use force against their own people, who continue to protest against the government tonight. The news came hours after six journalists who reported on the protests were released from custody.

Hosni Mubarak yesterday announced a new cabinet, which does not include several figures who protesters largely do not approve of. Analysts have, however, suggested little had changed within the government; many positions, they say, are filled with military figures.

In a statement broadcast on state media in Egypt, the army said: “To the great people of Egypt, your armed forces, acknowledging the legitimate rights of the people … have not and will not use force against the Egyptian people.” A BBC correspondent in Cairo said the announcement meant it “now seems increasingly likely that the 30-year rule of Mr Mubarak is drawing to a close.”

“The presence of the army in the streets is for your sake and to ensure your safety and wellbeing. The armed forces will not resort to use of force against our great people,” the statement added. “Your armed forces, who are aware of the legitimacy of your demands and are keen to assume their responsibility in protecting the nation and the citizens, affirms that freedom of expression through peaceful means is guaranteed to everybody.”

Earlier today, six journalists from the independent news network Al-Jazeera were released from custody after being detained by police. The U.S. State Department criticized the arrests; equipment was reportedly confiscated from the journalists.

Egyptian officials yesterday ordered the satellite channel to stop broadcasting in the country. Al-Jazeera said they were “appalled” by the government’s decision to close its Egyptian offices, which they described as the “latest attack by the Egyptian regime to strike at its freedom to report independently on the unprecedented events in Egypt.”

In a statement, the news agency added: “Al-Jazeera sees this as an act designed to stifle and repress the freedom of reporting by the network and its journalists. In this time of deep turmoil and unrest in Egyptian society it is imperative that voices from all sides be heard; the closing of our bureau by the Egyptian government is aimed at censoring and silencing the voices of the Egyptian people.”

On Friday, Wikinews reported the government had shut off practically all Internet traffic both out of and into the nation, as well as disrupting cellphone usage. A spokesperson for the social networking website Facebook said “limiting Internet access for millions of people is a matter of concern for the global community.”

A reported 50,000 campaigners, who are demanding the long-time leader step down and complaining of poverty, corruption, and oppression, filled Tahrir Square in Cairo today, chanting “We will stay until the coward leaves.” It is thought 100 people have so far died in the demonstrations. Today there have been protests in Suez, Mansoura, Damanhour, and Alexandria.

Speaking to news media in the area, many protesters said the new cabinet did little to quell their anger. “We want a complete change of government, with a civilian authority,” one said. Another added: “This is not a new government. This is the same regime—this is the same bluff. [Mubarak] has been bluffing us for 30 years.”

In Tahrir Square today, protesters played music as strings of barbed wire and army tanks stood nearby. Demonstrators scaled light poles, hanging Egyptian flags and calling for an end to Mubarak’s rule. “One poster featured Mubarak’s face plastered with a Hitler mustache, a sign of the deep resentment toward the 82-year-old leader they blame for widespread poverty, inflation and official indifference and brutality during his 30 years in power,” one journalist in the square reported this evening.

Jack A. Weil, founder and CEO of Rockmount Ranch Wear died on August 13 at the age of 107 in Denver, Colorado. He was the oldest working CEO in the United States. He was also known as “Papa Jack”.

He was born on March 28, 1901 in Evansville, Indiana. In 1946, Weil rented a space at 1626 Wazee Street in Denver and set about trying to create a fashionable yet practical identity for the western ranchers of the region.

Weil was well-known for coining the phrase “The West is not a place, it is a state of mind.” He was the first person to put snaps on Western shirts, patented the saw-tooth pocket design seen on many Western shirts, and was credited with inventing the bolo tie.

In 2001, he told Associated Press, “I learned fast you can’t sell to cowboys; they have no money. You have to appeal to the cowboy in everyone and sell to them.”

Among his customers were Ronald Reagan, Bob Dylan, Eric Clapton and Nicholas Cage. More recently, Rockmount shirts were worn by the late Heath Ledger and Jake Gyllenhaal in the 2005 Academy Award-nominated movie, Brokeback Mountain.

Weil’s wife, Beatrice Baum, died in 1990, followed by his son Jack B. in January 2008.

“I never wanted to be the richest man in the cemetery,” he told his grandson and current president of the family business.

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.

According to reports, a man protesting the G20 Summit in London, England has died after collapsing at a protester camp.

Sky News says the man collapsed on the street inside a camp close to the Bank of England and when found he was still breathing, but efforts by paramedics to rescue him failed and he was pronounced dead at an area hospital. The name of the person and cause of death are not yet known, but several people were injured earlier in the day. The police claim that protestors threw bottles at them while trying to rescue the protestor.

The London Ambulance Service reported that “we received a 999 call at 7:24 pm from a member of the public reporting that a man had fallen over and was unconscious, but was breathing. [They] made extensive efforts to resuscitate him both there and on the way to hospital.”

Earlier in the day a minimum of 20 protesters broke into the bank and according to reports vandalized furniture, broke windows and cut the telephone lines to the building.
