British explorer and mountaineer Edward “Bear” Grylls, has set a new altitude record by piloting a powered paraglider above Mount Everest reaching 29,494ft (8,990m). He and his fellow pilot, Giles Cardozo, who had invented and developed the parajet engine, set out on their attempt from the Himalayan village of Pheriche (altitude 14,435ft (4,400m)) in the early morning of 14th May.

Grylls, 33, is a mountaineer, best selling author and television presenter who spent three years with the elite British Special Air Service (“SAS”) forces. During this time he was involved in a horrific parachuting accident in which he broke his back in three places, almost severing his spinal cord. Remarkably, in 1998, after months of rehabilitation, he became at 23, the youngest British climber to scale Mount Everest and return alive.

Cardozo is considered to be one of the top paragliding pilots in the world, and it is reported that he and Grylls first came up with the idea for the attempt about a year ago when he had invented the engine that would take them up the mountain.

Grylls and Cardozo flew their paragliders together to 28,001ft (8,353m) surviving temperatures of minus 76°F (-60°C) and dangerously low oxygen levels, when a fault developed in Cardozo’s engine, and he had to abort his attempt just 984ft (300m) below the summit. Grylls went on to reach his record height at 09.33 local time. He had originally intended to cross the Mountain but turned back to base camp fearing that he might be arrested if he entered Chinese airspace.

On his return to Kathmandu, Grylls voiced his feelings of loneliness and exhilaration:

The attempt was sponsored by British technology and engineering group GKN. The project, GKN Mission Everest, raised £500,000 (approximately $1m) for Global Angels, a charity helping children in Africa, Asia and Latin America.

In a separate incident, a German paragliding champion has survived being sucked up by a storm to a height of 32,612ft (9,940m) whilst preparing for a world paragliding championship in Manilla, New South Wales, Australia.

Ewa Wisnierska, 35, the 2005 World Cup paragliding winner, lost consciousness and was covered in ice and battered by orange-sized hailstones as she was pulled upwards by the sudden tornado-like storm which she had been attempting to skirt. After regaining consciousness as she descended she was able to make contact with her ground team which had been tracking her by her GPS equipment, and landed safely 40 miles (60km) from where she took off.

Remarkably she spent only an hour in hospital after her experience, being treated for frostbite and blistering to her face and ears.

A fellow competitor, 42 year old Chinese man, He Zhongpin, who was also caught up in the storm, was not so fortunate and died from lack of oxygen and the extreme cold.

Officials in Mumbai, India, demolished over 6,000 shanties today in a push to eradicate the capital city’s slums. In total, 39,000 shanties have been flattened, displacing over 200,000 people, in the city’s biggest-ever demolition drive, which began in early December.

When complete, over 2 million people are expected to be displaced. After wiping out the least desirable shanties, next in line for demolition are the illegal ‘well-off’ shanties and neighborhoods, according to the legal and bureaucratic motions that have been executed toward cleaning up Mumbai’s appearance by lowering the dominance of shanties, which make up 62 percent of Mumbai’s housing.

“As far as eye can see, there are mounds of wood, tin and tarpaulin, the remains of 6,200 illegal homes, flattened by a heavy excavator running on tank-like tracks and giant motorised claws,” the Indian Express reported about today’s destruction. [1]

Chief Minister Vilasrao Deshmukh said that citizens would see a change within six months. “Every chief minister likes to be remembered, and I’m no exception,” said Deshmukh, who despite having an empty exchequer, also announced that Rs 31,000 crore will be spent on new roads, sea links and rail lines.

Buffalo, New York —The city’s Common Council met in Council Chambers today with a full agenda. Among the items in the agenda was the Elmwood Village Hotel proposal.

The Elmwood Village Hotel is a proposed hotel by Savarino Construction Services Corporation and is designed by architect Karl Frizlen of the Frizlen Group. It is to be placed on the corner of Elmwood and Forest Avenues in Buffalo and will require the demolition of at least five properties (1109-1121 Elmwood).

During the hour-and-a-half meeting, the Common Council approved the hotel proposal. The entire voting process for the proposal took less than two minutes, and the public was not allowed to speak. The Council voted unanimously in support of the proposal; however, the city’s Planning Board must also approve the proposal. The Board will meet on Tuesday, March 28, 2006 at 8:00 a.m. on the 9th floor of City Hall, room 902.

The approval allows for the rezoning of all five properties, including 605 Forest, to a “special development plan,” or a C-2 zone.

“There is a ‘special development plan’ in front of the council, which changes only one thing about the zoning. It allows one permitted use — for just a hotel. The rest of the zoning remains as it is under the current Elmwood Business District zoning. 605 and 607 Forest are not required for the project. They are not part of the footprint for the project. Let me answer this question again. This is on the record, in council: 605 needs to be rezoned in order to facilitate the project because of the sideyard requirement. Anything in C-2 is excluded besides the hotel. So we’ve taken the C-2 and included the hotel as a permitted use, and excluded everything else, and everything else remains the same,” Eva Hassett, Vice President of Savarino Consrtruction, said to Wikinews during a public meeting on March 16, 2006.

However, during the same meeting, Pano Georgiadis, owner of 605 Forest and owner of Pano’s Restaurant on Elmwood, threatened to “sue” Savarino Construction saying, “If you try to get a variance to change the code, I will sue you. This is my home, number one.”

Savarino Construction hopes to break ground this Summer.

Despite the Council’s approval, organizers have scheduled another protest that will be held this Saturday, March 25, 2006 at 2:00 p.m. on Forest and Elmwood.

Some citizens are even considering legal action and are considering an “injunction in State Supreme Court,” going “pro se, meaning I am going to present the case myself,” said Clarence Carnahan, a concerned citizen and local business owner who is opposed to the hotel, to Wikinews.

Carnahan wrote a “notice of cease and desist” which was also presented to the Council at today’s meeting.

Patty Morris, co-owner of Don Apparel with Nancy Pollina, said, “We are going to fight the good fight to the bitter end, but we cannot afford it [legal action]. Now it’s a legal matter, and it’s in the hands of the law, and I know there are some people very interested in hiring a lawyer.”

Nancy Pollina says that she is “looking into a defense fund” and is currently talking to lawyers.

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.

B2B Trade Area of Taipei Game Show, criticized by trade buyers last year, but accompanied with 2008 Taiwan Digital Content Forum, moved to the second floor at Taipei World Trade Center for world-wide participants with a better exchange atmosphere this year.

Not only local OBMs (Softstar Entertainment, Soft-World International Corp., International Games System Corp., …, etc.) but also companies from New Zealand, Canada, Japan, Hong Kong, and South Korea showcased different specialists with multiple styles. Especially on South Korea, participated members from G? Trade Show (Game Show & Trade, All-Round, aka Gstar) showcased gaming industry of South Korea and the G? upcoming at this November with brochures.

In the 2-days Digital Content Forum, world-class experts not only shared industry experiences, members from Taiwan Gaming Industry Association also discussed and forecasted marketing models for gaming industry. With participations from governmental, industrial, and academical executives world-wide, this forum helps them gained precious experiences of digital content industry from several countries.

According to the Taipei Computer Association, the show and forum organizer, the digital content industry in Taiwan was apparently grown up recent years as Minister of Economic Affairs of the Republic of China Steve Ruey-long Chen said at Opening Ceremony yesterday. Without R&Ds from cyber-gaming, and basic conceptions from policies and copyright issues, this (digital content) industry will be fallen down in Taiwan. If this industry wanted to be grown up in sustainability, gaming OBMs in Taiwan should independently produce different and unique games and change market style to market brands and games to the world.

A paste containing synthetic tooth enamel can seal small cavities without drilling. Kazue Yamagishi and colleagues at the FAP Dental Institute in Tokyo say that the paste can repair small cavities in 15 minutes.

Currently, fillers don’t stick to such small cavities so dentists must drill bigger holes. Hydroxyapatite crystals, of which natural enamel is made, bond with teeth to repair tiny areas of damage.

Yamagishi and colleagues have tested their paste on a lower premolar tooth that showed early signs of decay. They found that the synthetic enamel merged with the natural enamel. The synthetic enamel also appears to make teeth stronger which will improve resistance to future decay. As with drilling, however, there is still the potential for pain: The paste is strongly acidic to encourage crystal growth and causes inflammation if it touches the gums.

The paste is reported in the journal Nature.
