Thousands of spectators lined Queen St. in central Auckland, New Zealand to watch a parade of around 20 female porn stars riding topless on motorcycles. The girls, wearing studded knee-high leather boots and leather pants, braved a winter chill, nippy wind and objections by some city officials, in a shot at promoting an Auckland Erotica Expo happening later this week.

Auckland Mayor Dick Hubbard described the parade as “morally repugnant.”

Byrraju Ramalinga Raju, founder and chairman of Satyam Computer Services, and his brother, B. Rama Raju, the company’s managing director, were arrested late Friday by Andhra Pradesh police. The brothers were placed under judicial custody in a Hyderabad, India jail and will remain there until January 23. Facing charges of criminal breach of trust (Section 406 of IPC), criminal conspiracy (Section 120-B), cheating (Section 420), falsification of records and forgery (Section 468), and fraudulent cancellation of securities (Section 477-a), they face up to ten years imprisonment if convicted.

After 18 hours of interrogation by the Crime Investigation Department (CID) at the state police headquarters, the Raju brothers were sent to the Chanchalguda prison and slept Saturday night on the floor along with 26 other low-risk inmates.

S. Bharat Kumar, the Rajus’s lawyer, asked the magistrate to issue orders for health monitoring. “His blood pressure is fluctuating and he needs medical treatment,” said Bharat Kumar. Mr. Raju appeared before the court Saturday while a team of doctors visited him after he had complained of chest pain.

Raju has Hepatitis-C, and both brothers have high blood pressure, so health precautions are necessary while imprisoned. Prison rules mandate service of jail food thrice a day. The menu includes 650 gm of rice thrice a day with 250 gm of vegetable curry and 125 gm of ‘daal’ plus tea twice a day.

Satyam’s chief financial officer Vadlamani Srinivas, who was also arrested Saturday, had undergone preliminary investigation and appeared Sunday before a special court, according to A. Sivanarayana, Andhra Pradesh additional director general of police. Srinivas was remanded to judicial custody until January 23 by Mr. D. Ramakrishna, Sixth Chief Metropolitan Magistrate, and sent to the Chanchalguda jail with the Raju brothers after interrogation by CID’s Crime Branch (the CB-CID). During his Saturday night arrest and probe by CB-CID, Srinivas made revelations which are contained in his confession letter as submitted to Network 18. “According to me fixed deposits are unreal and fictitious which were managed and was an understanding between the audit section management,” Srinivas stated.

The Hyderabad court on Monday postponed the bail hearings of the Raju brothers and Srinivas to January 16. To be defended by a battalion of 25 lawyers, the three accused will remain in Chanchalguda Central Jail until further court order. The Raju brothers were shifted Sunday to a mid-size Old Hospital Barrack cell shared with a bootlegger.

In 2008, the company struggled to purchase two infrastructure companies founded by family members of company founder and CEO Dr. Raju – Maytas Infrastructure and Maytas Properties – for $1.6 billion, despite concerns raised by independent board directors. Dr. Raju tendered his resignation on January 7 after due notice of falsified accounts to board members and the SEBI.

Since January 7 when two lawsuits were commenced, dozens of other class action law suits were filed against Satyam for hundreds of millions of dollars damages based on fraud in the United States District Court for the Southern District of New York in Manhattan, among others. The securities fraud class-action lawsuits have been filed on behalf of investors who bought Satyam American Depositary Receipts (ADRs) since 2004.

On Wednesday Dr. Raju admitted to falsifying and overstating Satyam’s cash reserves by $1B US dollars (£661m) or 94% of its cash and bank balances on books at the end of September.

The fraud was perpetrated several years ago to bridge “a marginal gap” between actual and accounting books operating profits, and continued for several years. “It was like riding a tiger, not knowing how to get off without being eaten,” B. Raju said.

In a letter to the board, Dr. Raju said that neither he nor the managing director had benefited financially from the inflated revenues. Further claiming that none of the board members had any knowledge of the dire company situation, he noted that Satyam’s balance sheet as of the September 30, 2008, carried inflated figures for cash and bank balances of INR 5,040 crore (as against INR 5,361 crore reflected in the books). He alleged it also carried an accrued interest of INR 376 crore which was non-existent. He confessed that he himself prepared an understated liability of INR 1,230 crore on account of funds amid an overstated debtors’ position of INR 490 crore (as against INR 2,651 crore in the books).

Indian analysts have compared the Satyam-Raju scandal to the infamous American Enron scandal. Immediately following the media expose, PricewaterhouseCoopers, auditor of Satyam’s accounts, was set to be probed for complicity in the controversy. Times Now has reported that the Andhra Pradesh CID arrested PricewaterhouseCoopers (PWC) representative Gopal Krishnan for investigation on Saturday night.

New York-listed Satyam Computer Services Ltd., India’s fourth-biggest software firm, is a consulting and information technology services company based in Hyderabad, India. Founded in 1987 by Dr. Byrraju Ramalinga Raju, Satyam’s network spans 67 countries on six continents. It employs 53,000 professionals in India, the United States, the United Kingdom, the United Arab Emirates, Canada, Hungary, Singapore, Malaysia, China, Japan, Egypt and Australia. Its monthly salary outflow is estimated at six billion rupees ($125 million). Deriving more than half of its revenues from the United States, it serves 700 global companies, 185 of which are Fortune 500 corporations.

Satyam’s clients include Nestle, Ford, General Electric Co., General Motors Corp., Nissan Motor Co., Applied Materials Inc., Caterpillar Inc., Cisco Systems Inc. and Sony Corp., and brought in about $40bn last year.

In December 2008, a failed acquisition attempt involving the company Maytas led to a plunge in Satyam’s share price. After Wednesday’s confession, Satyam stocks fell further by more than 70%, while the BSE SENSEX dropped to 7.3% Wednesday, causing the removal of Satyam Computer Services from its indices on Thursday. The shares free fell to 11.50 rupees on Friday, their lowest level since March 1998, compared with around last year’s high of 544 rupees.

The New York Stock Exchange has terminated trading in Satyam stock as of January 7, while the National Stock Exchange of India said it will remove Satyam from its S&P CNX Nifty 50-share index from January 12.

India’s biggest-ever corporate fraud has seriously tainted India Inc.‘s strong corporate governance image. “The admission of fraud in financial affairs has created an adverse impression in the minds of trade, business and industry across the world,” the Indian government admitted. The government intervened on Friday night, dismissing Satyam’s board of directors, announcing it will appoint representatives to manage the affairs of the insolvent outsourcing giant. The board would meet within seven days. Dr Yeduguri Samuel Rajasekhara Reddy, chief Minister of State of Andhra Pradesh, India, on Sunday said that the main agenda is to protect the jobs of the software professionals. “We are taking all needful steps in coordination with the government of India to ensure that the jobs of 53,000 engineers are protected and the shareholders’ money is salvaged,” Reddy said.

“We are working on the names. The Satyam case is an aberration. The credibility of the Indian corporate sector in general, and IT sector in particular, should not be allowed to suffer because of this.” Prem Chand Gupta, the Corporate Affairs Minister said. The Federal Government of India appointed a three-member independent board with full authority for Satyam on Sunday and was set to convene within 24 hours. “We have appointed Deepak Parekh, chairman of Housing Development Finance Corporation, Kiran Karnik, former president of IT industry body NASSCOM and C. Achutan, former member of Securities and Exchange Board (SEBI) of India,” Mr. Gupta said.

In early Monday trading (0535 GMT) after the creation of the three-member board, Satyam shares rocketed upwards 60% to 38.15 rupees, even though the main Mumbai market was down more than 2%. BBC reported that Satyam shares have jumped 51% to 36.05 rupees on Monday after the stock lost 87% last week. “The constitution of the new board is seen as a positive step by the market. It’s a confidence boosting measure,” K.K. Mital, Globe Capital, New Delhi head of portfolio management services said. “But the rally will depend largely on the financial situation at the company and the kind of measures that are taken to improve liquidity,” he added.

The Company Law Board, however, has requested Satyam’s interim board not to implement its decisions. “We are asked by the Company Law Board not to implement the decisions of the board. But we are allowed to continue our activity. The team which was constituted recently is continuing its work,” Satyam head global marketing and communications, Mr. Hari Thalapalli, said.

Lazard Ltd., who has a 7.4% stake in Satyam, sought representation on the new board and wrote as much to The Indian Ministry of Corporate Affairs. “As the largest shareholder in the company, we want to be consulted in whatever decisions are being taken by the Indian government. We have written to the Ministry of Corporate Affairs and are awaiting a reply from them,” Hitesh Jain, a partner at ALMT Legal, who claimed to represent Lazard, said. “It is a fair proposal and we will take a decision as and when we clear other issues. No decision on this has been taken yet,” P.C. Gupta replied.

Meanwhile, the Securities and Exchange Board of India (SEBI) also announced it will try to control the damage and take steps to boost investor confidence. “This exercise will be undertaken after the third quarter results and is expected to be completed by end of February this year,” a SEBI official statement said. A SEBI team is also investigating acting-CEO Ram Mynampati whose salary was greater than that of founder Dr. Raju and all the directors combined. Dr. Raju had just one fifth of Mynampati’s total package of over Rs 3.5 crore as of March 2008. All the directors comparably received only a total of Rs 2.6 crore as salary, commissions, sitting fees, professional fees and other receivables.

Further, the Andhra Pradesh Police CID and teams assigned by the Economic Offences Wing of the CB-CID conducted searches Sunday of homes of the accused including the ex-CFO’s office to gather documentary evidence about the financial fraud.

Last week’s announcement that most soda manufacturers will stop selling their sugary products in U.S. schools did not mention that avoiding lawsuits was part of the motivation for the self-imposed ban. Some of those who threatened legal action to stop the soda sales are patting themselves on the back over the agreement, while lamenting that the deal did not go far enough, and now plan to press for more restrictions.

“Though there is room for improvement — sugary “sports” drinks still will be sold in schools, for instance — this voluntary agreement is certainly good enough that CSPI will drop its planned lawsuit against Coca-Cola, PepsiCo, Cadbury-Schweppes and their bottlers,” said Michael F. Jacobson, the executive director of the Center for Science in the Public Interest . “I hope this settlement contributes to the momentum that is building in Congress for legislation that would require USDA to update its standards for foods sold outside of school meals. That would enable USDA to eliminate the sale of candy, cookies, French fries, potato chips, and other snack foods, as well as sports drinks, that are standard fare in school vending machines and stores.”

In the wake of the announcement of the agreement by the three largest soft drink companies, their bottlers and the public health advocacy group, the Alliance for a Healthier Generation, Jacobson thanked his team of litigators for “negotiating effectively with the soft-drink industry over the past six months, and for demonstrating that the judicial system can play an important role in spurring public health advances.”

Richard Daynard, a law professor and president of the Public Health Advocacy Institute, which threatened the soft-drink industry with lawsuits, said in an institute press release, “The industry agreement with the Clinton Foundation and American Heart Association comes after sustained pressure from potential litigation and negotiations with public health groups and their lawyers. It is a credit to the role of litigation and the legal system as a component of effective public health strategy.”

“This agreement demonstrates the potential of public health litigation to help control the obesity epidemic,” he said.

In an email exchange with the James Logan Courier, Margo Wootan, director of Nutrition Policy for the Center for Science in the Public interest, said, “Last week’s announcement that soft drink companies will pull all sugary sodas from schools is great step toward improving school foods. This agreement is the culmination of the tremendous national momentum on improving school foods — from the local policies (in LA, NYC, Chicago, Philadelphia, DC, etc.), state bills (in 2005, 200 bills were introduced in 40 states to get soda and junk foods out of schools), the strong bipartisan bill pending in the U.S. Congress, and threats of litigation against soda companies.”

“While today’s agreement is a huge step forward, it is by no means the last step” wrote Wootan, ” We still have a lot of work to do to improve school foods.”

The agreement, announced Wednesday morning by the William J. Clinton Foundation, means that the nation’s biggest beverage distributors, and the American Beverage Association, will pull their soda products from vending machines and cafeterias in schools serving about 35 million students, according to the Alliance for a Healthier Generation, a joint initiative between the Clinton Foundation and the American Heart Association.

Under the agreement, high schools will still be able to purchase drinks such as diet and unsweetened teas, diet sodas, sports drinks, flavored water, seltzer and low-calorie sports drinks for resale to students.

The companies plan to stop soda sales at 75 percent of the nation’s public schools by the 2008-2009 school year, and at all schools in the following school year. The speed of the changes will depend in part on school districts’ willingness to change their contracts with the beverage distributors.

Some food activists criticized the deal for not going far enough and undermining efforts to go further.

Michele Simon, the director of the Center for Informed Food Choices, based in Oakland, Ca., called the deal “bogus” and a “PR stunt” by “Big Cola” in an effort to “sugar coat it’s image.”

“This announcement could potentially undermine ongoing grassroots efforts, state legislation, and other enforceable policies,” wrote Simon in an article at www.commondreams.org,” For example, in Massachusetts where a stronger bill is pending, a local advocate is worried about the adverse impact, since legislators could easily think that Clinton has taken care of the problem and ignore the bill. What was already an uphill battle—getting schools and legislatures to take this problem seriously—was just made worse, not better, by this bogus agreement.

“Even from a health standpoint, the deal is hardly impressive. Diet soda full of artificial sweeteners, sports drinks high in sugar, and other empty-calorie beverages with zero nutritional value are still allowed in high schools,” Simon wrote, “Also, parents concerned about soda advertising in schools will not be pleased with the agreement. Not a word is mentioned about the ubiquitous marketing children are subjected to daily in the form of branded score boards, school supplies, sports bags, and cups (just to name a few), which is required by exclusive Coke and Pepsi contracts. “

She’s not the only one criticizing the deal.“ While the initial details are promising, PHAI is concerned about some aspects of the agreement as it is being reported,” Daynard said in the press release. “The continual sale of “sports drinks” is a cause for concern. While they have a role for marathon runners and others engaged in sustained strenuous sports, for most students “sports drinks” are just another form of sugar water. Furthermore, the change in beverages offered must be carefully monitored and cannot depend entirely on the schools’ willingness and ability to alter existing contracts. Soda companies have spent decades pushing these unhealthy drinks on children and should bear the responsibility for their removal. PHAI is also concerned about the enforcement of this agreement and its silence on industry marketing activities in the school system,” he said.

“Importantly, the agreement doesn’t address the sale of chips, candy, snack cakes, ice cream, or any of the other high-fat, high-calorie, high-salt foods that are sold widely in schools,” said Wootan of the Center for Science in the Public Interest, “This is a voluntary agreement and is not enforceable, we need Senator Harkin’s school foods bill to lock in the beverage standards and give them the force of law.”

Even the diet drinks, which will still be offered, need to go, said Ross Getman, an attorney in Syracuse, NY. Getman has advocated that soda should not be sold in public schools and that long-term “pouring rights” agreements, which give a company exclusive access to sell their brands at a school, are illegal for a variety of reasons.

Getman, who contends that some diet sodas are contaminated with benzene, a cancer-causing chemical, said the soda “industry gets an “F” for incomplete” for “the industry’s failure to pull all soda from school and to recall products.”

Schools account for about $700 million in U.S. soft-drink sales, less than 1 percent total revenue for Coca-Cola, PepsiCo and Cadbury, the nation’s largest soda companies.

Ten of the largest U.S. school districts have already removed soft drinks from vending machines, according to Getman. States including California, Maine and Connecticut have also banned sugary sodas in schools.

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.

Yesterday, Belgian Archbishop Godfried Danneels visited the Catholic University of Leuven to give a lecture on health care and religion, entitled “Care for the body, care for the mind”. Some 120 people, mainly professors at the University Hospitals, but also clerics and students, attended the conference and following piano recital.

In his introduction speech, Dean of Medicine Bernard Himpens reminded the audience how much the art of medicine had changed since the time of Andreas Vesalius, probably the Faculty’s most famous scientist. The Dean stressed the important role of the Hospital’s Biomedical Ethics Committee, but added that religion continues to be important.

“Some people even believe that good ethics must be carried by faith, and any profound ethics should result in faith,” the Dean noted. He asked the question where the evolution of a merely “passive tolerance for the Christian starting points” would lead the health care system.

In his lecture, the Archbishop acknowledged that the technical aspects of health care were probably the most important to achieve results, but that on the other hand, the medical-technical approach by itself could not guarantee the happiness of the patients.

Wikinews asked Professor Martin Hiele, Chairman of the Commission for Medical Ethics, if he felt there was a need for a lecture on the subject of religion and health care. He replied that

Prof. Bernard Spitz, from the University’s Department of Developmental Biology and head of the Hospital’s Obstetrics Department, told Wikinews that

The lecture was organised by the DeGroof Bank and the Faculty of Medicine. It is the first of three lectures on the subject of religion, spirituality and ethics in health care.

Children of Men, a movie based on a P.D. James book, has won the 2006 USC Scripter Award for its writing. Both the original author, James, and the screenwriting team will be honored by the University of South California for their work.

The winning screenwriters are Alfonso Cuaron, Timothy J. Sexton, David Arata, Mark Fergus, and Hawk Ostby. The Children of Men was James’ 12th book, written in 1992.

USC School of Cinematic Arts Writing Division Chair Howard A. Rodman commented

For nineteen years, the USC Libraries Scripter Award has honored “writers for the best achievement in adaptation among English-language films released during the previous year and based on a book, novella or short story.” While there are many awards for either screenwriting in general, or adapted screenwriting, the Scripter is the only award to recognize both the screenwriters and the original authors.

Also nominated was:

• screenwriter Aline Brosh McKenna and author Lauren Weisberger for The Devil Wears Prada
• screenwriter Neil Berger for The Illusionist, based on the story “Eisenheim the Illusionist” by Steven Millhauser
• screenwriters Peter Morgan and Jeremy Brock for The Last King of Scotland, based on the book by Giles Foden
• screenwriter Patrick Marber and author Zoe Heller for Notes on a Scandal

The titles were selected by committee, from a list of forty-five eligible films. The committee is made of Writers Guild of America members (including some Academy Award-winning screenwriters and Academy Award-nominated screen writers), authors, film industry executives, USC faculty, the dean of the USC Libraries, and selected members of the Friends of the USC Libraries, the sponsor of the event.

Previous screenwriters and authors honored include the teams behind Capote, Million Dollar Baby, The Hours, A Beautiful Mind, L.A. Confidential, The English Patient and Schindler’s List.

Theoretical physicist John Archibald Wheeler died of pneumonia at his residence in Hightstown, New Jersey yesterday. Wheeler is most known in the popular culture for popularizing the term “black hole” to describe stars which had become so dense that nothing, not even light, could escape their gravitational pull. Although Wheeler initially objected to the idea, he later accepted the idea and coined the term “black hole” to describe such objects.

Wheeler was also known for his work along with Richard Feynman and others in the Manhattan Project, which produced the first nuclear fission bomb. He was later involved in the work to build the first fusion bomb. As much as he was known for his research, Wheeler was known for his skill and accomplishment in teaching.

Wheeler was born July 9, 1911, in Jacksonville, Florida and went on to earn his doctorate in physics at the early age of 21. He then went on to work in Copenhagen with Niels Bohr and later returned to the United States to become part of the Manhattan Project during World War II.

Wheeler continued to work in physics after the war and was involved in the United States Matterhorn project to build a hydrogen bomb before the Soviet Union. His politics were more militaristic than many of his fellow scientists at the time, in that he supported the Vietnam War and the building of the hydrogen bomb.

For a long time Wheeler was at Princeton University as the doctoral adviser for many prominent physicists including Kip Thorne and Nobel Prize winner Richard Feynman. Wheeler went on to the University of Texas at Austin in 1976 when Princeton’s mandatory retirement age neared.

Wheeler continued to work until near his death. Physicists both young and old have paid tribute to Wheeler; cosmologist Max Tegmark told the New York Times that Wheeler had been “the only physics superhero still standing”.

He is survived by three children, along with grandchildren and great-grandchildren.

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.

Another population of small humans has been reported, this time in caves in Micronesia.

Lee Berger, Steven Churchill, Bonita De Klerk and Rhonda Quinn, a team of paleontologists and anthropologists from South Africa and the United States document a group of “small-bodied humans” found in the ” in limestone caves in the rock islands of Palau, Micronesia.” The report, in a recent edition of the open access journal, PLoS ONE (2008 3:3) argues that these small people may “represent a congenitally abnormal individual drawn from a small-bodied island population of Homo Sapiens.” The term for this condition is Insular Dwarfism described in Foster’s Rule. Different radio carbon samples at the site date between 3000 and 4500 calendar years before the present, with the 3000 year old dates being judged the most reliable.

The authors argue, “Based on the evidence from Palau, we [Berger et al] hypothesize that reduction in the size of the face and chin, large dental size and other features noted here may in some cases be correlates of extreme body size reduction in H. sapiens.”

Unlike the 2004 find of the Flores dwarf human population (dated from 95,000 to 13,000 years ago), known as Homo floresienses and nicknamed hobbits, researchers do not consider this population to be a separate hominid population. They also suggest that this more recent population casts some doubt on H. floresienses being a separate species, and that,

“These features when seen in Flores may be best explained as correlates of small body size in an island adaptation, regardless of taxonomic affinity…[This] Palauan sample supports at least the possibility that the Flores hominins are simply an island adapted population of H. sapiens, perhaps with some individuals expressing congenital abnormalities.”

In support of this, Berger et al also argued that although the dwarf humans appeared to have many features in commons with Homo sapiens, there seems to be many features that are not usually associated with Homo sapiens.
