The Svalbard Global Seed Vault, a vault containing millions of seeds from all over the world, saw its first deposits on Tuesday. Located 800 kilometers from the North Pole on the Norwegian island of Spitsbergen, the vault has been referred to by European Commission president José Manuel Barroso as a “frozen Garden of Eden“. It is intended to preserve crop supplies and secure biological diversity in the event of a worldwide disaster.

“The opening of the seed vault marks a historic turning point in safeguarding the world’s crop diversity,” said Cary Fowler, executive director of the Global Crop Diversity Trust which is in charge of collecting the seed samples. The Norwegian government, who owns the bank, built it at a cost of $9.1 million.

At the opening ceremony, 100 million seeds from 268,000 samples were placed inside the vault, where there is room for over 2 billion seeds. Each of the samples originated from a different farm or field, in order to best ensure biological diversity. These crop seeds included such staples as rice, potatoes, barley, lettuce, maize, sorghum, and wheat. No genetically modified crops were included. (Beyond politics they are generally sterile so of no use.)

Constructed deep inside a mountain and protected by concrete walls, the “doomsday vault” is designed to withstand earthquakes, nuclear warfare, and floods resulting from global warming. Norwegian Prime Minister Jens Stoltenberg called it an “insurance policy” against such threats.

With air-conditioned temperatures of -18 degrees Celsius, experts say the seeds could last for an entire millennium. Some crops will be able to last longer, like sorghum, which the Global Crop Diversity Trust says can last almost 20 millenniums. Even if the refrigeration system fails, the vaults are expected to stay frozen for 200 years.

The Prime Minister said, “With climate change and other forces threatening the diversity of life that sustains our planet, Norway is proud to be playing a central role in creating a facility capable of protecting what are not just seeds, but the fundamental building blocks of human civilization.” Stoltenberg, along with Kenyan Nobel Peace Prize laureate Wangari Maathai, made the first deposit of rice to the vault.

“It is very important for Africa to store seeds here because anything can happen to our national seed banks,” Maathai said. The vault will operate as a bank, allowing countries to use their deposited seeds free of charge. It will also serve as a backup to the thousands of other seed banks around the world.

“Crop diversity will soon prove to be our most potent and indispensable resource for addressing climate change, water and energy supply constraints and for meeting the food needs of a growing population,” Cary Fowler said.

The Saskatoon Health Region in Saskatchewan, Canada recently discovered a fax machine problem which had not relayed almost 1,500 X-rays, Computed tomography (CT) and Magnetic resonance imaging (MRI) scans, ultrasounds, and other medical imaging test results to doctors.

The fax machine is part of the automated Radiology Information System. An audit revealed that medical diagnostic tests involving results dating back a decade have been affected by the broken fax machine.

On May 6, a doctor called the health region officials seeking follow up on a patient’s report. Staff who delved into it, found that the report was not sent from the system.

Now, two weeks later, this same patient has still not been contacted by the health region.

“It has taken some time to work with the patient’s physician. That was important — to get more information and more detail because we want that patient’s physician to be involved in the discussion with the patient,” Dr. David Poulin, vice-president of medical affairs for The Saskatoon Health Region, said. “This is a system error and that’s just what it was — an error. This doesn’t reflect in any way on the quality of work regional staff have done and continue to do.”

An internal review revealed that, of 2.2 million diagnostic tests performed, at least 1,380 had not been sent out by the malfunctioning fax machine.

The health region will embark on contacting each of the 1,380 patients and their physicians to make sure that the results have been received and if any health care was compromised.

Patients can also contact the health region via a newly set up hotline to make enquiries.

“We think it would actually be good practice if physician offices could have a system to check whether they have received important reports,” said Poulin, “The common practice appears to be in many doctors’ offices, particularly family physician offices, that they don’t respond to the report until it arrives. So, they basically are waiting for the report to arrive in their office by fax and it’s at that point that they look at it and decide what action to take.”

City Hospital, St. Paul’s Hospital and Royal University Hospital were the three city hospitals affected. Saskatoon has a population of roughly 233,923, and the hospitals also serve the surrounding rural areas.

Ironically the faulty fax machine was discovered the same week that provincial medical officials began to review approximately 70,000 radiology tests conducted in Yorkton. Officials there doubt the competence of the physician who first interpreted the radiology results.

A launch failure occurred at NASA’s Wallops Flight Facility in Virginia on Tuesday.

The failure occurred when Orbital Sciences Corporation’s Antares rocket, which was carrying the Cygnus vehicle with cargo of 5,000 pounds (about 2,300 kg), exploded after liftoff at 6:22 p.m. local time (2222 UTC), creating a massive fireball in the sky. Nobody was reported injured during the explosion, but the rocket was destroyed. The cargo was supplies for the International Space Station (ISS). Despite the explosion, the astronauts working on the ISS will not run out of food or supplies, according to a NASA statement released on Tuesday.

Orbital’s vice president Frank Culbertson said the contractor’s spacecraft will not fly until the cause of the failure is determined. NASA plans to continue the mission of delivering supplies to astronauts once it fully understands how this happened.

The rocket was to launch on Monday night, but a boat entered the hazard area, delaying the launch until the following night.

The cause of the explosion is under investigation by NASA and Orbital Sciences. NASA said the National Transportation Safety Board is monitoring the investigation.

A Pembroke Pines, Florida teenager killed himself Wednesday, November 19, while broadcasting on the live video site Justin.tv. After making suicide threats and being encouraged by Justin.tv viewers and Bodybuilding.com forum members, Abraham K. Biggs, 19, committed suicide by taking an overdose of opiates and benzodiazepine, which had been prescribed for his bipolar disorder.

Biggs first began blogging about his planned suicide 12 hours before the actual event. He died after taking pills and lying on the bed in front of the webcam. After the broadcast, viewers who apparently thought it was a hoax posted messages such as “OMG”, “LOL”, and “hahahah”.

Hours later, after being alerted by viewers who had noticed that Biggs had stopped breathing, law enforcement and paramedics arrived, discovered his body, and covered the camera. The Broward County Medical Examiner’s Office has reportedly confirmed Biggs’ death.

According to Montana Miller of the Bowling Green State University, the circumstances of this case were not shocking: “If it’s not recorded or documented, then it doesn’t even seem worthwhile. For today’s generation it might seem, ‘What’s the point of doing it if everyone isn’t going to see it?'”

Biggs’ sister Rosalind was angry that neither the website nor its viewers reacted soon enough to save him. “They got hits, they got viewers, nothing happened for hours,” she said. She described him as “very happy” and “friendly and outgoing.” “On a normal day, you couldn’t really tell that he got as low as he did.” However, he did have relationship problems with his girlfriend, according to a friend.

Mental health professionals have warned about the possibility that other mentally troubled people would copy his actions. According to Dr. David Shaffer of Columbia University, “Any video showing it as heroic or romantic or glamorous could reduce the anxiety people might feel about suicide. It becomes a respectable behavior and lowers the threshold of suicide.” He and other psychiatrists recommend that potentially suicidal teens talk to others and “tell what’s going on.”

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.

7,810 Jeep SUVs are to be recalled in order to address a software vulnerability in the vehicles’ entertainment systems which allows the vehicles to be “hacked” — allows vehicle software security to be compromised — Fiat Chrysler Automobiles US (FCA US) said on Friday. This recall affects some 2015 model Jeep Renegades.

FCA US said exploiting the vulnerability would take “unique and extensive technical knowledge, prolonged physical access to a subject vehicle and extended periods of time to write code.” They said there are no known instances where the software vulnerability has caused injury to anyone.

They said owners of affected cars can fix the software vulnerability by inserting a device containing a software patch into a USB port inside the car.

Another 1.4 million vehicles manufactured by the company have also been recalled last month, when white hat hackers discovered they were able to hack and disable the engines of the affected vehicles remotely.
