The United States Food and Drug Administration (FDA) has recalled 380 million eggs and the number is expected to grow, after around 300 in Colorado, California, and Minnesota and 2,000 nationwide became infected with salmonella after eating eggs distributed by Wright County Eggs.

The contaminated eggs were sold under the labels Lucerne, Albertson, Mountain Dairy, Ralph’s, Boomsma’s, Sunshine, Hillandale, Trafficanda, Farm Fresh, Shoreland, Lund, Dutch Farms, Kemps, Bayview, Mountain Dairy, NuLay and Sun Valley. Eggs have been sold in seventeen states.

Wright County Egg’s owner has been previously cited for breaking environmental laws.

In response to the outbreak the FDA deployed an initial team of ten investigators to Wright County Egg in Iowa to inspect the farms and determine the source of the contamination. Although no official statement has been issued, it is believed animals including birds and rodents defecated where food for chickens is stored.

The outbreak is believed to have started in early July, around the time new federal regulations to prevent salmonella contamination of eggs took effect.

According to the FDA, the symptoms of salmonella infection includes fever, diarrhea, nausea, vomiting, and abdominal pain.

20-year-old pitching phenom Phil Hughes cruised through hitters in just his second start for the New York Yankees, but the end result created even more frustration for the organization and fans everywhere.

Hughes retired 19 Texas Rangers without allowing a hit on Tuesday at the Rangers Ballpark in Arlington. Established big league stars such as Kenny Lofton, Mark Teixeira and Michael Young could not solve the youngster’s blazing fastball or sharply biting curve. Hughes was on the verge of history. Even as his pitch count rose, the Yankees allowed him to keep firing. “He was fine,” manager Joe Torre said of the 2004 first round draft pick. “We were going to allow him to go 100 pitches last time, so I didn’t think that would be a problem.”

Just when the Yankees thought they found an answer to their early struggles, the organization was treated to an agonizing sight. After Teixeira fouled off an 0-2 pitch with one out in the sixth inning, Hughes grabbed his leg, having suffered a hamstring injury. His no-hit bid ended there (Texas would break up the no-hitter in the eighth inning off reliever Mike Myers), though he did earn his first big league win in a 10-1 Yankee romp over Texas. He walked off the mound under his own power, but will reportedly miss 4-6 weeks.

Hughes voiced his frustration afterwards: “It’s tough. It puts a damper on the whole thing.” He added, “I’m at a point now where our rotation really needs it,” referring to his presence on the New York pitching staff. Several Yankees have already voiced their excitement for the righthander’s chances in the big leagues. For his part, Yankees star Jason Giambi compared him to Roger Clemens during Spring Training: “He looks like a young Rocket.”

The Yankees are currently just 10-14, thanks in large part to injuries that have befallen pitchers Chien-Ming Wang, Mike Mussina, Carl Pavano and Jeff Karstens. In a related story from today, the Yankees fired strength and conditioning coach Marty Miller. Reportedly, this was out of general manager Brian Cashman’s concern for the alarming number of hamstring injuries so far this season.

Possible under reporting of bird flu infections in China and other Southeast Asian countries may be promoting an illusory sense that human infections are very limited. Common press reports only describe fewer than 130 people as infected with H5N1 avian flu and that fewer than 70 have died worldwide. Yet, there are enormous problems getting accurate data, especially in a country like China with a population of more than a billion.

“Reporting a suspected bird flu infection in bird or humans is a very unlikely event,” said Dr. Shoshana Zimmerman of the eHealth Institute. She is also a founder of www.birdflubeacon.com, a site dedicated to bird flu issues. “There are very few incentives to report, and lots of reasons to refrain from reporting. From the viewpoint of local rural small farmers, there is little to be gained and much to be lost by reporting an infection. The worse threat is that their flocks could be killed, leaving them destitute.”

There are many factors which mitigate against reporting bird or human infections of bird flu.

• The deaths of chickens, ducks, and birds are common events for farmer. Even when a large number die at one time they may see no purpose in reporting the deaths.

• When a human dies in locations with little or no medical services, the rural farmer’s priority for discerning the cause of death may be low.

• In rural areas most people are not taken to hospitals when they are sick.

• Bird flu symptoms are not widely known. If the symptoms are not known, they will not be recognized and reports of possible bird or human infections can not be made.

• The expenses required for detection are those of proper collection and shipment of samples to one of approximately 200 laboratories worldwide, as well as the testing procedure that requires a two week period of waiting before results are obtained.

• The lack of incentive for countries to report large scale outbreaks as it may lead to widespread panic and economic loss, as occurred with SARS. These factors can be seen at work in the way that the first bird flu death was reported in China,” Dr. Zimmerman stated.

A young woman, Zhou Maoya, died after returning home to the village of Yantan in Annui province to prepare for her wedding. Her family has stated that they did not take her to the hospital because they thought it would not do any good. Officials also note rural Chinese also often cite relatively expensive medical costs as a reason for not seeking treatment when sick.

Although initially authorities attributed her death to pneumonia the resulting political pressure prompted China to invite the World Health Organization to send experts to investigate. The authorities then rescinded the previous position and attributed her death to bird flu based on the similarity of the symptoms that she was reported to exhibit with those of bird flu. The village was quarantined and journalists were denied access. It is not known how many others might be infected in the village. Official announcements were made of plans to vaccinate and cull birds.

A local government official, Fan Qian, told AFP that it was believed Zhou was infected while she was outside of the province.

Fan Tan, a local official, told AFP news that 1,000 birds in Yantan had been culled (killed). Plans were announced to vaccinate 2 million poultry in the area, a huge and difficult task.

Zhang, another official, said authorities had met with all villagers to give them flu vaccinations and to tell them how to protect themselves against the bird flu virus, including not consuming poultry products. It is known that flu vaccinations do not protect against bird flu.

Villagers and local officials minimized the threat. In outlying areas of Yantan, residents said that they did not know of any new outbreaks. Other possible infections have been attributed to similar common causes but there have not been any tests performed validating those attributions.

Fan Litan, a peasant woman from Fantu village, about 2 miles from Yantan, lost many of her ducks, and chickens and also a dog; she has attributed these deaths to the acts of hooligans. She said her family had been extremely frightened when her animals suddenly died. “We were scared to death,” said Fan, standing next to a red sign posted on the outside wall of her home that said: “Prevention and control by the masses is basic for people.” Fan said ducks and chickens are all healthy but she admitted that she had stopped eating poultry. No testing of these birds has been reported yet.

According to a recent AFP report from Liuchang, 59 miles south of Yantan, the obstacles to identifying infections are enormous.

Like many, one Liuchang villager named Wang Hemin said he was concerned and would keep a closer eye on his ducks and chickens, but felt no immediacy since the infection was not in his province. He learned about bird flu on TV, and is aware that officials have come to his village of 2,700 people to warn residents about the virus. They offered guidelines: they told people that poultry which die suddenly could have contracted bird flu and should not be eaten or sold and that such an incident should also immediately be reported. However, the symptoms of H5N1 bird flu were not directly described.

Residents have not yet been fully informed of what symptoms to look for in ill poultry–they are fever, diarrhea, teary eyes and swelling in the legs of the birds. Though a pledge was made earlier in the week to vaccinate 2 million birds immediately, no bird vaccinations in this area have been reported yet.

In another nearby village, Nazahuang, chickens scuttle in and out of houses. One resident, Fan Jiexu, 73, said no officials had yet warned her village to take precautions. Throughout rural areas, it is customary for chickens to scuttle in and out of homes. Ducks and bird often die and are eaten by villagers when it is believed safe to do so.

China has reported 17 avian flu outbreaks as of this week. Despite the Chinese government issued high alerts, critical information is not being adequately communicated to some rural villages. The size of the poultry population, the common and normal occurrence of poultry death on farms, and status of roughly 70% of the poultry population as being kept in backyards are factors complicating infection control.

The head of World Health Organization’s China office, Henk Bekedam, is aware that slow reaction to bird flu threats and difficulty monitoring poultry in the world’s most populous country makes control of its spread challenging.

Testing is required to confirm H5N1 virus, and positive test results lead to the killing of nearby flocks. The incentive for many villagers, officials, and governments to minimize reports of H5N1 virus infections and severe medical and economic complications for making confirmations of infection are obstacles opposing complete and full reporting of the spread and infection rates of the virus.

In Buffalo New York, a suspicious package was received by National Action Financial Services, a subsidiary of Sitel, Inc.. According to FBI spokesperson Earl Gould Buffalo, the initial call was placed at 10:30AM EST Yesterday. The mail department found the package, evacuated the building, and contacted the local police department. The package has been described as containing some type of white powder.

The police department then contacted the Department of Homeland Security, who finished at the scene by 3:00PM EST.

After interviews with several employees were refused, one agreed – after being only identified as KR. He said management was being very “hush hush” about the incident, but when he came in he jokingly said that it was a “regular day at work now”.

National Action Financial media contacts were not available for comment, and the Amherst Police Department referred Wikinews to the local FBI office.

Special Agent Earl Gould stated as of 4:30PM no hospitalizations were required, but could not comment further as it is an ongoing investigation. He also stated the first responders to the scene did “everything right, and contained it immediately.”

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.

Fiji’s national airline Air Pacific has now officially returned to its original name: Fiji Airways. Fiji Airways adopted the Air Pacific name in 1971, slightly prior to its first international flight on June 3, 1973. The re-brand was described by interim CEO Aubrey Swift as allowing the airline to align itself “closer with Fiji as a destination”. The name change is designed in part to reduce the confusion which surrounded the name Air Pacific. Swift noted that “Air Pacific just didn’t resonate with our customers” and said that same people “thought we were an air conditioning company”.

Along with the name change, the airline has redesigned its website, and changed the name of each of its classes of service. Pacific Voyager and Tabua Class have been replaced with economy and business class respectively. The airline has also introduced plans to overhaul its fleet of older Boeing 747s with Airbus A330s. It has said that the completion of this overhaul and the re-branding efforts will be completed by the end of the year.

The airline’s new brand-mark and livery features a masi design created by Fijian artist, Makereta Matemosi. The new identity is to “symbolises the airline’s new identity and epitomises all that Fiji Airways represents. It is authentic, distinctive, and true to the airline’s Fijian roots”, the airline said.

Vandals have caused thousands of British pounds worth of damage at a city railway station. The Bath Spa railway station in Bath was targeted by vandals over the weekend. Graffiti was sprayed over the new tourist centre as well as the stone work which is over 100 years old. The disabled toilets were also vandalised.

First Great Western who owns Bath Spa station released a statement through spokesman Dan Panes saying, “last year we invested a considerable amount of money improving the station environment at Bath Spa for our customers, and it’s a great shame that a couple of minutes of vandalism could cause so much damage.”

The vandalism comes just months after a mini police station was opened up in the station to combat anti-social behaviour. The behaviour in Bath was said to be worse than that of the centre of Liverpool.

CCTV has been passed on to the British Transport Police and are currently assessing the damage caused.
