Service to millions of Internet users in the Middle East and Asia has been disrupted, following damage to undersea cables.

The cables, SEA-ME-WE 4 and FLAG, which provide communications services for various countries — including India, Pakistan, Egypt, and Saudi Arabia — are believed to have been damaged by a ship attempting to moor off Egypt on Wednesday, January 30, 2008.

One day later, on February 1, the FALCON cable was also reported cut 56 km off Dubai. Repair ships have been sent to both breaks, with capacity to India expected to reach 80% of its usual speed by Friday, February 2.

According to the telecommunications provider Qtel, a fourth cable linking Qatar to the United Arab Emirates was damaged on Sunday, February 3.

A total of five cables being operated by two submarine cable operators have been damaged with a fault in each.

A car accident involving the car occupants and a dentist’s office happened on Sunday night in Santa Ana, California. A white Nissan sedan which was apparently driving too fast hit the raised concrete median on the road, after which it was launched into the air, slamming straight into the wall of the second floor of a two-story dental practice building, where the car got wedged.

According to the police, the car approached from a side street. The room of the dental office penetrated by the sedan was used as a storage space. A fire department crane was used to extract the vehicle from the building, which took several hours.

There were two people in the sedan. One of them managed to escape from the hanging vehicle on his own, while the other one remained trapped inside it for over an hour. They were both hospitalized with minor injuries, according to the Orange County Fire Authority (OCFA). According to the police, the driver of the car admitted narcotics use, and after toxicology tests the case is to be submitted to the Orange County District Attorney’s Office.

The moment of the accident was captured by surveillance video from a bus which the car narrowly missed when becoming airborne.

According to OCFA spokesperson Captain Stephen Horner, there was a small fire after the crash, which was extinguished quickly.

United States President Barack Obama will get the chance to make his first United States Supreme Court appointment as a number of unnamed sources close to Associate Justice David Souter announced the Justice’s retirement from the body, to take place in June.

NPR suggests that Souter was waiting to confirm that colleagues John Paul Stevens, now 89, and Ruth Bader Ginsburg, who has cancer, were not retiring in the coming year before making his decision; the earliest public indication of his retirement was the April 29th discovery by the Associated Press that unlike the eight other Justices, Souter had not hired a staff for the upcoming session of the Supreme Court, which begins in October.

A spokesperson for the Justice said that Souter had no comments on the reports of his retirement.

Souter, currently 69, retires from the court as the sixth-oldest justice, but his departure is unlikely to change the court’s ideological balance. While appointed by Republican President George H. W. Bush in 1990, Souter has consistently voted as a member of the court’s center-left bloc and a liberal nomination by Obama would likely be confirmed by a majority in the United States Senate.

The Supreme Court is the highest judicial body in the United States; its decisions on the interpretation of the Constitution can be overridden only by a constitutional amendment.

On Friday, German football captain and Manchester United F.C. midfielder Bastian Schweinsteiger announced retirement from international football.

Debuting in 2004, Schweinsteiger has won 120 international caps, Germany’s fourth all time most capped player. He was part of the German squad for the UEFA Euro 2016 tournament in France and became the first German to play eighteen Euro matches, surpassing the fourteen-match record of Philip Lahm. Schweinsteiger has played in four Euro tournaments — 2004, 2008, 2012, and 2016.

Schweinsteiger said, “I have asked the national team coach to not consider me for Germany selection in future, as I would like to step down from the national team. I would like to thank the fans, the team, the DFB, the coaches and the national team’s backroom staff.” ^{((de))German language: ?ich habe soeben den Bundestrainer gebeten, mich in Zukunft bei der Nominierung für die Nationalmannschaft nicht mehr zu berücksichtigen, da ich gerne zurücktreten möchte. Mein Dank gilt den Fans, der Mannschaft, dem DFB, den Trainern und dem Team um die deutsche Nationalmannschaft.}

Schweinsteiger won the 2014 FIFA World Cup in Brazil. He has featured in three FIFA World Cup tournaments — in 2006, 2010 and 2014. He has played 38 matches in major international tournaments, which is a world record. Schweinsteiger’s last match in Germany’s jersey ended in a 2–0 defeat against France in the Euro 2016 semi-final.

After Schweinsteiger announced his retirement, his former Bayern Munich teammate and German player Thomas Müller tweeted, “Thanks for 120 international caps with the @DFB_Team [German Team] and many great and shared hours with the national team” ^{((de))German language: ?Danke für 120 Länderspiele im @DFB_Team [Deutschland Mannschaft] und viele großartige, gemeinsame stunder bei der Nationalmannschaft}.

Officials say that progress is being made in a deal to bail out three United States carmakers. The U.S. government will be holding weekend talks on the plan after two days of Congressional hearings.

Dana Perino, the White House press secretary, stated that discussions with both parties had been “constructive”.

Executives from the three companies – General Motors, Ford, and Chrysler – have pleaded before two Congressional committees, asking for $34 billion in order to stop collapse.

“I’m convinced that by Sunday we will have an agreement that people can understand on this bill,” said Barney Frank, a representative from the state of Massachusetts.

The Archbishop of York, Dr John Sentamu, said that Zimbabwe’s president Robert Mugabe must be forced out of office and face trial for his crimes against humanity.

“The time has come for Robert Mugabe to answer for his crimes against humanity, against his countrymen and women and for justice to be done. The winds of change that once brought hope to Zimbabwe and its neighbours have become a hurricane of destruction, with the outbreak of cholera, destitution, starvation and systemic abuse of power by the state,” said Sentamu.

Sentamu that the power-sharing deal that was signed by Mugabe and the Zimbabwean opposition in September was “now dead”.

Dr Sentamu’s statement comes after a severe cholera outbreak spread in Zimbabwe, and saw 12,545 cases reported and 565 people dead.

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.
