Methicillin-resistant staphylococcus aureus (MRSA), a drug-resistant strain of bacteria, killed nearly 19,000 Americans in 2005 alone, according to a new study in the Journal of the American Medical Association. That is more people than were killed by AIDS in the United States. More than 94,000 Americans were afflicted with MRSA infections in 2005.

Although the supergerm, or superbug, is primarily found in hospitals, a growing number of cases have been contracted at public gyms and schools. In Moneta, Virginia, a high school senior died from an infection that spread to his kidney, liver, lungs and heart. In Bedford County, where Moneta is located, school officials have reported five cases of the Methicillin-resistant strain of the Staph bacteria. County officials closed the schools to clean them.

“Certainly, MRSA now has to be viewed as a very important target for prevention and control,” said Dr. David A. Talan, an infectious diseases specialist at Olive View-UCLA Medical Center.

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:

According to theory, a quantum state can encode any amount of information (at zero temperature), requiring only sufficiently high bandwidth and time in which to read it out. In practice, only recently has progress been made towards encoding several bits into the shapes of bosonic single-photon wave functions, which has applications in quantum key distribution. We have experimentally demonstrated that 35 bits can be permanently encoded into a time-independent fermionic state, and that two such states can be simultaneously prepared in the same area of space. We have simulated hundreds of stacked pairs of random 7 times 5-pixel arrays as well as various ideas for pathological bit patterns, and in every case the information was theoretically encodable. In all experimental attempts, extending down to the subatomic regime, the encoding was successful and the data were retrieved at 100% fidelity. We believe the limitations on bit size are approxlambda/4, but surprisingly the information density can be significantly boosted by using higher-energy electrons and stacking multiple pages holographically. Determining the full theoretical and practical limits of this technique—the trade-offs between information content (the number of pages and bits per page), contrast (the number of measurements required per bit to overcome noise), and the number of atoms in the hologram—will involve further work.Quantum holographic encoding in a two-dimensional electron gas, Christopher R.

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.

On May 9, Moscow heralded its celebrations of Victory Day with one of the largest military parades seen since the fall of the Soviet Union through the Red Square and the streets of Moscow. Signifying the defeat over Nazi Germany in 1945 in World War 2, Victory Day continues to be one of the most poignant and emotional celebrations and national holidays in Russia. Estimates of more than 27 million lost lives during the war continues to leave a vein of sadness in Russia.

Victory day began early in Moscow with inner city streets being closed from 6am and the major entrance of Tverskaya Ulitsa completely locked down with all access to non-military blocked until the end of the parade. Tens of thousands of people lined the upper parts of Tverskaya to see the exit of the military as well as the air force fly-over on their entrance to Red Square. In total more than 9,000 troops, 69 planes and a huge collection of armored vehicles, tanks, and massive anti-aircraft missile defense systems ensured that Moscovites and the rest of Russia will remember Victory Day 2009.

In scenes reminiscent of the end of the war military bands played around the city until all hours of the night. At Leningradsky station departing veterans and widows danced and celebrated with younger generations whilst loudly singing the national anthem. As trains departed, staff handed out flowers in recognition of the contributions made and loud cheers were heard across the many platforms. In a touching event it seemed to bond the generations of yesterday and today.

Preparations for the military parade began months ago with regular rehearsals in Alabino including the erection of a mock Red Square and Kremlin to ensure authenticity. Final dress rehearsals took place in Moscow on May 7 including a full practice of the air show. On display for the first time was the S-400 air defense system which is capable of intercepting airborne targets at ranges up to 400 kilometers (249 mi).

Following the official parades and ceremonies, Red Square and the the inner city was opened to the public, albeit under extreme security and an ever watching eye from Interior Ministry troops. During the afternoon there was an estimated crowed of over 100,000 which entered Red Square to admire the parade ground and decorations, including the official stand for the dignitaries.

Closing the festivities was a series of fireworks in fourteen different locations throughout Moscow including the grand display over the Kremlin and Red Square.

Atlanta Falcons quarterback Michael Vick and three other men were indicted on Tuesday by a federal grand jury on charges of conspiracy related to a dog fighting operation. The charges included buying, breeding and training pit bull dogs, transporting the dogs across state lines to illegally participate in fights, and gambling on the fights.

The indictments stemmed from a search of Vick’s Smithfield, Virginia home in April, in which 54 pit bulls were removed, along with equipment used in dog fighting.

The indictment said that Vick had bought the property in Smithfield for US$34,000 to run the dog fighting under the name “Bad Newz Kennels” with two other people named in the indictment. Purnell Peace, Quanis Phillips, and Tony Taylor were all named in the indictment along with Vick.

The indictment stated that Vick took part in the killing of eight dogs that didn’t pass test fights, called “rolling”. The pit bulls were allegedly killed by hanging, drowning and slamming at least one dog onto the ground.

If convicted of both portions of the conspiracy charge, Vick could face six years in prison and a $350,000 fine. His property, located in Surry County, would be subject to forfeiture under U.S. laws dealing with illegal activities that are carried out at an interstate level. The indictment alleges that the dog fighting operation, involving American Pit Bull Terriers, spilled over into Alabama, North Carolina and New York.

Vick has a court date on July 26 for a bond hearing and to hear the charges. Vick has said that he had a kennel operation on the property, but had no involvement or knowledge of a dog fighting ring.

Companies in the United States are shedding more jobs, pushing the country’s unemployment rate to a 26-year high of 9.8%.

The US Labor Department said on Friday that employers cut 263,000 jobs in September, with companies in the service industries — including banks, restaurants and retailers — hit especially hard. This is the 21st consecutive month of job losses in the country.

The United States has now lost 7.2 million jobs since the recession officially began in December 2007. The new data has sparked fears that unemployment could threaten an economic recovery. Top US officials have warned that any recovery would be slow and uneven, and some have predicted the unemployment rate will top 10% before the situation improves.

“Continued household deleveraging and rising unemployment may weigh more on consumption than forecast, and accelerating corporate and commercial property defaults could slow the improvement in financial conditions,” read a report by the International Monetary Fund’s World Economic Outlook, predicting that unemployment will average 10.1% by next year and not go back down to five percent until 2014.

Mark Zandi, chief economist at Moody’s Economy.com, said that “it’s a very fragile and tentative recovery. Policy makers need to do more.”

“The number came in weaker than expected. We saw a lot of artificial involvement by the government to prop up the markets, and now that that is starting to end, the private sector isn’t yet showing signs of life,” said Kevin Caron, a market strategist for Stifel, Nicolaus & Co.

Also on Thursday, the US Commerce Department said factory orders fell for the first time in five months, dropping eight-tenths of a percent in August. Orders for durable goods — items intended to last several years (including everything from appliances to airliners) — fell 2.6%, the largest drop since January of this year.

The US government has been spending billions of dollars — part of a $787 billion stimulus package — to help spark economic growth. There have been some signs the economy is improving.

The Commerce Department said on Thursday that spending on home construction jumped in August for its biggest increase in 16 years. A real estate trade group, the National Association of Realtors, said pending sales of previously owned homes rose more than 12 percent in August, compared to August 2008.

A separate Commerce Department report said that consumer spending, which accounts for more than two-thirds of US economic activity, rose at its fastest pace in nearly eight years, jumping 1.3 percent in August.

Other reports have provided cause for concern. A banking industry trade group said Thursday the number of US consumers making late payments, or failing to make payments, on loans and credit cards is on the rise. A survey by a business group, the Institute for Supply Management, Thursday showed US manufacturing grew in September, but at a slower pace than in August when manufacturing increased for the first time in a year and a half.

Stock markets reacted negatively to the reports. The Dow Jones Industrial Average fell 41 points in early trading, reaching a level of 9467. This follows a drop of 203 points on Thursday, its largest loss in a single day since July. The London FTSE index fell 55 points, or 1.1%, to reach 4993 points by 15.00 local time.

The auction hammer came down Wednesday, in London, on Judy Garland’s blue gingham dress, worn in the 1939 movie “The Wizard of Oz.” It sold for £140,000 (about US$262,157.40).

The identity of the buyer, who sealed the deal on the telephone, was not immediately revealed. Bonham auctioneers told reporters there was a pre-sale estimate of £35,000 (about US$65,529.47).

The dress, one of the most recognizable in the movie world, was made for the 17-year-old Garland who had a 27-inch (68-centimetre) waist. Her name is still on a tag on an inside hem. It was auctioned as part of a sale of rock and film memorabilia and was described as a “cherished memory for millions of fans worldwide.”

The story of the “Wizard of Oz,” which sealed Garland’s legend as a worldwide star, tells the story of a young Kansan, Dorothy (Judy Garland) and her dog Toto. They are whisked away from their rural Kansas home by a tornado to a magical realm called OZ.

In their travels, they meet other now-famous characters, the Scarecrow, the Tin Man, and the Cowardly Lion.

Although the film started with only modest success, it has since become a screen classic.

The eruption of volcano Tungurahua on August 16 destroyed several small villages in the Ecuadorian Andes. At least 6 people have been killed and about 4000 residents of the affected area have been evacuated.

The 5,023 m high volcano spat lava, stones and ash for several hours on Wednesday night. A 10km high ash cloud spread over an area of 740 by 180 km. Towns like Ambato or Riobamba, 30 km away from the volcano have been covered with up to 5cm of ash. Pyroclastic flows descending on the northwestern slopes of the volcano left a path of destruction behind.

At least seven small villages and hamlets have been completely destroyed. The ash and rocks blocked the Chambo and the Peula river and the road Ambato – Baños, one of the main connections between the Ecuadorian highlands and the Amazon region. The Institute for Geophysics has lost an important part of its equipment installed on the slopes of Tungurahua, limiting their capability to monitor the volcanic activity.

The Hydroelectric power plant Agoyan near Baños has been shut down since Wednesday night. On Thursday, air traffic in the whole country was limited due to ash layers on several airports. On Thursday the provinces of Chimborazo, Tungurahua, Cotopaxi and Bolivar have been declared a disaster area. Losses in agriculture due to the ash cover are estimated at $150 Million.

On Friday, volcanic activity decreased to a calm that remained into Saturday evening, but the Ecuadorian Institute for Geophysics warns that a further eruption may be imminent.

In 1999, after a long period of rest, the volcano started an eruptive process that continues to this day. After the first eruptions in October 1999 that produced a major ash out-fall and led to the temporary evacuation of more than 25,000 inhabitants of Baños and its surroundings, the activity continued on a medium level. In May 2006 it increased dramatically culminating in violent eruptions on July 14 and August 16.

Kivimetsän Druidi? is a Finnish female-fronted band formed in 2002 whose music is a fusion of symphonic, fantasy and folk metal, which the band’s website dubs ‘Rock ‘N’ Troll’.

Brothers Joni and Antti Koskinen formed the band in Kouvola with Joni playing guitar and growling while Antti played keyboard and sings backing vocals. They joined up with a female lead vocalist, lead and bass guitarists and a drummer. The brothers write the songs between them, with Antti doing the main body and Joni writing the lyrics.

Together the band recorded and released three demos and an EP, all released independently, across 2002-6. Across October and November 2007 they gained international attention by supporting well-known Finnish folk metal band Korpiklaani across a large European tour.

On June 6 this year Kivimetsän Druidi? was announced to have been signed to Century Media Records in a global deal. The band have now entered Noice Camp studio in Turku to record their debut, with a planned release date in October. This summer the only performances will be at a handful of festivals while the band works on their new album, but after that is released a major tour will follow to support it. The band say they are “extremely pleased” with the deal.

Wikinews was able to discuss these events and what the future holds for the band with the Koskinen brothers and female vocalist Leeni-Maria Hovila, who also writes the vocal melodies in an exclusive interview, which is published below for the first time.

New ‘deadly’ sexual enhancement products have been found in Singaporean markets and can cause serious side effects on users.

The Health Sciences Authority (HSA) announced the presence of the illegal drugs, known as Power 1 Walnut, Santi bovine penis erecting capsule, Zhong Hua Niu Bian and fake Cialis, which have been discovered over the past 3 months. Santi bovine penis erecting capsule has been found to contain high amounts of glibenclamide, a potent drug used to treat diabetes. The tablets also contain sildenafil and tadalafil – potent western medicines used to treat erectile dysfunction. Zhong Hua Niu Bian also contains sildenafil and glibenclamide.

High consumption of the tablets can be potentially deadly as the glibenclamide in the capsules can lead to drastically reduced blood sugar levels which can lead to seizures, stroke, coma or death. Consuming half of a Power 1 Walnut capsule has led to unconsciousness and frothing at the mouth.

Consumption of Power 1 Walnut has led to the death of a middle age man last week who fell into a coma. Currently, one death and two cases of coma have been reported from the total of 89 hospitalised cases linked with the consumption of the illegal drugs. It has been revealed that patients obtained the drugs by purchasing them from illegal peddlers located in various parts of Singapore.

The HSA has advised people to stop consuming the drugs and to report on any cases of consumption to them.
