This past Sunday, Illinois Governor Pat Quinn signed into law a bill known as “Rocky’s Law” that requires Illinois high schools, through the local school district, to buy catastrophic injury insurance up to US$3 million or medical costs for up to five years, whichever one comes first, that covers student athletes. The insurance must cover student athletes while they are competing.

The legislation was named after Rasul “Rocky” Clark. In 2000, the Eisenhower High School football player became paralyzed from the waist down as a result of a tackle during a game. His school based health insurance covered the costs of his medical treatment. A legislator sponsoring the bill noted that the need for this type of insurance is rare. Clark’s mother attended the legislation signing. Her son died last year.

Before parents can claim money from school insurance, they first must pay out US$50,000. Schools have until January 1, 2014 to comply with the law. Schools cannot charge students more than US$5 to defray the cost of insurance. If a school district already requires student to be covered through private health insurance, they are exempted from this law.

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.

Dani Jarque, the Captain of the Spanish football team Espanyol, has died from a heart attack at the age of 26.

Jarque was practicing during pre-season training at Coverciano in Italy earlier in the day. He was staying in the team hotel ahead of a match planned for Sunday against Bolonia.

Jarque was sharing a room with another player, Ferran Corominas who says Jarque was talking to his girlfriend when he went to dinner on Saturday night. When Jarque fell silent over the phone, his girlfriend called the hotel who alerted Corminas. He then went back to the hotel room and found Jarque unconscious. Although he was taken to a local hospital, all efforts to revive him were unsuccessful.

“The doctor carried out CPR on the player and used a defibrillator, which showed that the arrest was non responsive. RCD Espanyol, broken with pain, wish to put themselves at the absolute disposition of the family of our captain Dani Jarque, to whom go our warmest thoughts,” said the team in a statement to the press. The team has canceled their planned practices in Italy and will return to Spain.

Jarque had been named captain of the side last July, replacing Raúl Tamudo. He joined team Espanyol at the young age of 12 and played his first match in 2002.

Controversy has arisen over the reported presence of blue asbestos on the MV Freewinds, a cruise ship owned by the Church of Scientology. According to the Saint Martin newspaper The Daily Herald and the shipping news journal Lloyd’s List, the Freewinds was sealed in April and local public health officials on the Caribbean island of Curaçao where the ship is docked began an investigation into the presence of asbestos dust on the ship. Former Scientologist Lawrence Woodcraft supervised work on the ship in 1987, and attested to the presence of blue asbestos on the Freewinds in an affidavit posted to the Internet in 2001. Woodcraft, a licensed architect by profession, gave a statement to Wikinews and commented on the recent events.

According to The Daily Herald, the Freewinds was in the process of being renovated by the Curaçao Drydock Company. The article states that samples taken from paneling in the ship were sent to the Netherlands, where an analysis revealed that they “contained significant levels of blue asbestos”. An employee of the Curaçao Drydock Company told Radar Online in an April 30 article that the Freewinds has been docked and sealed, and confirmed that an article about asbestos ran in the local paper.

Lloyd’s List reported that work on the interior of the Freewinds was suspended on April 27 after health inspectors found traces of blue asbestos on the ship. According to Lloyd’s List, Frank Esser, Curaçao Drydock Company’s interim director, joined Curaçao’s head of the department of labor affairs Christiene van der Biezen along with the head of the local health department Tico Ras and two inspectors in an April 25 inspection of the ship. “We are sending someone so that they can tell us what happened, where it came from, since when it has been there,” said Panama Maritime Authority’s director of merchant marine Alfonso Castillero in a statement to Lloyd’s List.

The Church of Scientology purchased the ship, then known as the Bohème, in 1987, through an organization called Flag Ship Trust. After being renovated and refitted, it was put into service in June 1988. The ship is used by the Church of Scientology for advanced Scientology training in “Operating Thetan” levels, as well as for spiritual retreats for its members. Curaçao has been the ship’s homeport since it was purchased by the Church of Scientology.

According to his 2001 statement, Lawrence Woodcraft had been an architect in London, England since 1975, and joined Scientology’s elite “Sea Organization” (Sea Org) in 1986. He wrote that he was asked by the Sea Org to work on the Freewinds in 1987, and during his work on the ship “noticed a powdery blue fibrous substance approximately 1 ½” thick between the paint and the steel wall,” which he believed to be asbestos. He also discovered what he thought was blue asbestos in other parts of the ship, and reported his findings to Church of Scientology executives. Woodcraft discussed his experiences in a 2001 interview published online by the Lisa McPherson Trust, a now-defunct organization which was critical of the Church of Scientology.

Church of Scientology spokeswoman Karin Pouw responded to Radar Online about the asbestos reports, in an email published in an article in Radar on May 1. “The Freewinds regularly inspects the air quality on board and always meets or exceeds US standards,” said Pouw. She stated that two inspections performed in April “confirmed that the air quality is safe,” and asserted that the inspections revealed the Freewinds satisfies standards set by the United States Occupational Safety and Health Administration and the U.S. Clean Air Act.

Pouw told Radar that “The Freewinds will be completing its refit on schedule.” The Church of Scientology-affiliated organization Citizens Commission on Human Rights (CCHR) had been planning a cruise aboard the Freewinds scheduled for May 8, but according to Radar an individual who called the booking number for the cruise received a message that the cruise had been delayed due to ongoing work on the ship. Citing an article in the Netherlands Antilles newspaper Amigoe, Radar reported on May 6 that a team from the United States and supervised by an independent bureau from the Netherlands traveled to Curaçao in order to remove asbestos from the Freewinds.

“I stand by everything I wrote in my 2001 affidavit,” said Lawrence Woodcraft in an exclusive statement given to Wikinews. Woodcraft went on to state: “I would also comment that if the Church of Scientology claims to have removed the blue asbestos, I just don’t see how, it’s everywhere. You would first have to remove all the pipes, plumbing, a/c ducts, electrical wiring etc. etc. just a maze of stuff. Also panelling as well, basically strip the ship back to a steel hull. Also blue asbestos is sprayed onto the outer walls and then covered in paint. It’s in every nook and cranny.”

Many Scientologist celebrities have spent time aboard the Freewinds, including Tom Cruise, Katie Holmes, John Travolta, Kelly Preston, Chick Corea, Lisa Marie Presley, Catherine Bell, Kate Ceberano, and Juliette Lewis. Now magazine reported that Tom Cruise has been urged to seek medical attention regarding potential asbestos exposure, however a representative for Cruise stated he has “absolutely no knowledge” of the recent asbestos controversy. Cruise, Holmes, Travolta and Preston have celebrated birthdays and other events on the Freewinds.

In a May 15 statement to the United Kingdom daily newspaper Metro, a representative for the Church of Scientology said that “There is not now and never has been a situation of asbestos exposure on the Freewinds.” The Asbestos and Mesothelioma Center notes that agencies have recommended anyone who has spent time on the Freewinds consult with their physician to determine if possible asbestos exposure may have affected their health.

Raw blue asbestos is the most hazardous form of asbestos, and has been banned in the United Kingdom since 1970. Blue asbestos fibers are very narrow and thus easily inhaled, and are a major cause of mesothelioma. Mesothelioma is a form of cancer which can develop in the lining of the lungs and chest cavity, the lining of the abdominal cavity, or the pericardium sac surrounding the heart. The cancer is incurable, and can manifest over 40 years after the initial exposure to asbestos.

“This is the most dangerous type of asbestos because the fibres are smaller than the white asbestos and can penetrate the lung more easily,” said toxicologist Dr. Chris Coggins in a statement published in OK! Magazine. Dr. Coggins went on to note that “Once diagnosed with mesothelioma, the victim has six months to a year to live. It gradually reduces lung function until the victim is no longer able to breathe and dies.”

Mehmet Okur scored 12 of the last 14 points for the Utah Jazz in the final minutes of their game against the Chicago Bulls on Monday night, propelling the Jazz to a 100-95 win against the Bulls. Okur finished with 20 points and was the high scorer for the Jazz, who now have won three in a row. He played most of the fourth quarter despite picking up a fifth foul early in the final period. In addition to Okur’s contribution, Deron Williams contributed 18 points and 13 rebounds in the effort.

Kirk Hinrich was the game’s leading scorer with 26 points, and Luol Deng contributed 23. However, the Jazz shot 50% from the field and dished out 24 total assists. The Bulls could not match those numbers, only shooting 40% and earning 15 assists. The lack of ball movement was obvious early on, as the Bulls committed three offensive fouls in the second quarter – all as the result of Bulls players attempting to drive the ball rather than pass and try to break the effective zone of the Utah Jazz. Ben Gordon also picked up a flagrant foul early in the second quarter, starting off what would be an ugly twelve minutes for the visiting Bulls. The Bulls were outscored 33-18 in the second quarter, leaving them down 57-43 at the half.

It almost wasn’t enough of a lead for the Jazz, as the Bulls were able to fight back and cut the lead to three with a three-point shot from Chris Duhon with 1:20 remaining in regulation time. However, the Jazz answered right back with an Okur three-point field goal, and the Bulls could not recover. While the Bulls would answer back with another field goal, the Jazz would score the next four points and pull away with the victory.

• Andres Nocioni was scratched with a foot injury. Team doctors believe that he may have a torn or inflamed plantar fascia; MRI results are not due back for another day or two. [1]
• Jazz coach Jerry Sloan received a technical foul for arguing with the officials midway through the fourth quarter.
• Earlier in the day, the Bulls’ Tyrus Thomas was named as one of the four participants in the 2008 Slam Dunk Competition during All-Star Weekend in Las Vegas.

Wednesday, February 23, 2005A compound in the common daisy-like plant feverfew kills human leukemia stem cells and could form the basis for newer, more effective drugs for the disease.

American researchers at the University of Rochester Medical Center in New York say that it could take months to develop a useable drug from the compound, parthenolide.

However, they are working to do so with chemists at the University of Kentucky who have identified a water-soluble molecule with the same properties. The US National Cancer Institute has also accepted the work into its rapid access program, which aims to speed experimental drugs into human clinical trials.

“This research is a very important step in setting the stage for future development of a new therapy for leukemia,” says Rochester researcher Craig Jordan. “We have proof that we can kill leukemia stem cells with this type of agent, and that is good news.”

Parthenolide appears to target the roots of myeloid leukemia, stem cells, while current treatments including the relatively new drug Gleevec don’t. So, “You’re pulling the weed without getting to the root,” says Jordan.

Used for centuries to fight fevers, inflammation and arthritis, feverfew earned interest from the Rochester researchers after other scientists showed that it could prevent skin cancer in animal models.

So the researchers investigated how a concentrated form of the plant component parthenolide would affect leukemia cells and normal cells.

Comparing the impact of parthenolide to the common chemotherapy drug cytarabine, they found that parthenolide selectively killed leukemia cells while sparing normal cells better.

While the findings suggest that parthenolide is a good starting point for new drugs, people with leukemia aren’t being encouraged to take high doses of feverfew as they could not take enough of the remedy to halt the disease.

The research is reported in the journal Blood.

North America’s largest outdoor dog festival came back to Toronto last weekend for its fifth year. It ran from the 9th of June to the 10th of June at Toronto’s historical St. Lawrence Market. A Wikinews reporter was there on Sunday to report on some of the events that happened on the last day.

The “Woofstock” dog festival attracted as many as 140,000 people with their dogs. The festival had tons of accessories, sold under tents, to buy for dogs; food, toys, designer clothes, and more. About 400 vendors and exhibitors were there to promote their products, which also gave private dog companies or groups a chance to show their new products. The local SPCA and some animal rescues were under tents answering questions from visitors. While walking, all visitors could see the CN Tower and other very tall buildings.

One of the local TV stations, Citytv, was there. They hosted a live event at the show which was broadcast on TV. People came up on the stage and asked questions regarding their dogs and the host and co-host answered them.

A man, who called himself the “Chalk Master”, drew two pictures on pavement with chalk. He did it for free but donations were welcome. One was a picture of a girl’s head beside a dog’s head, and another with a wolf.

“Hello Humans. I’ve been invited here to provide your eyeball(s), with some pretty colours. I don’t get paid as I work this weekend strictly for tips… so, if you like what you see please make a DONATION. If you don’t like it simply reach into the pocket of the person next to you and give me their money. CHALK MASTER.”

A contest called “Canada’s top dog” had its own tent with a professional photographer taking pictures of dogs behind a white screen; the winning photo is to be published on the cover of “Puppy and dog basics” magazine.

Large “Gourmet” dog bones were also served from a cart and table.

Next year’s festival is expected to be bigger and better with even more attractions.
