Pioneer modern Anaesthetic techniques Thomas Cecil Gray, born 11 March 1913 in Liverpool, died peacefully 5 January 2008 at home in Formby. A requiem mass was held at Liverpool Metropolitan Cathedral on 26 January 2008.

Born in Liverpool in 1913, educated at Ampleforth College, he qualified in medicine at The University of Liverpool in 1937. He began his career as a General Practitioner before joining the Royal Army Medical Corps.

He later returned to the University to become Head of the Department of Anaesthesia and was made Dean of the Faculty of Medicine in 1970, retiring in 1976. As Senior Lecturer he established the Department of Anaesthesia at Liverpool University, the ‘Liverpool technique’, based on the triad of unconsciousness, analgesia and muscle relaxation, was developed as a result.

Professor Gray was the editor of the British Journal of Anaesthesia from 1948 to 1964. Until recently Professor Gray continued to give occasional lectures at the university.

Professor Gray was presented with a CBE by Queen Elizabeth and in 1982 was honoured by Pope John Paul II who made him a Commander of the Order of St. Gregory the Great. In 2007 the Liverpool Echo included him in its list of the 800 greatest Liverpudlians, as part of Liverpools 800th anniversary.

Married twice. He married his first wife Marjorie Kathleen Hely in 1937 they had 2 children, she died in 1978; He married Pamela Mary Corning in 1979, they had 1 son. He had four grandchildren.

According to the International Maritime Bureau (IMB), pirates have seized a Greek bulk carrier en route to Kenya with 25 crew on board in the Gulf of Aden some 370 kilometers from Mogadishu, the capital of Somalia.

Noel Choong, who represents the International Maritime Bureau, advised ships traveling through the gulf to take extra precautions. “It appears that the pirates are now attacking ships in two areas, the eastern part of Somalia and northern parts of the Horn of Africa nation,” he said. “Ships are warned to take extra measures and stay 200 nautical miles away from the coast. They must maintain a strict watch.

The Gulf of Aden is a dangerous place for ships, with many incidents of piracy occurring regularly in the Gulf.

Four hours earlier pirates had attacked another vessel, a chemical tanker from Hong Kong, which was at the time carrying 22 crew members. Following that attack, the gulf was described by the managing director of the Hong Kong Shipowners Association as an “incredibly dangerous place.”

In response to this, several large shipping organisations have called for countries to deploy forces from their Navies in the Gulf of Aden.

“The shipping industry’s plea is in response to a situation which it describes as in danger of spiralling completely and irretrievably out of control,” said the group which consisted of the International Chamber of Shipping, Intercargo, Bimco and Intertanko. “Continued inaction against these violent acts could prompt shipowners to redirect their ships via the Cape of Good Hope, with severe consequences for international trade, including increased prices for delivered goods.”

The group also said that there have been 40 hijackings in the gulf, resulting in 133 crew members being kidnapped and 10 ships being held. According to the IMB six gangs totalling approximately 1,200 people have carried out these attacks.

Tuesday, March 29, 2005A team of Australian surgeons yesterday reattached both hands and one foot to 10-year-old Perth boy, Terry Vo, after a brick wall which collapsed during a game of basketball fell on him, severing the limbs. The wall gave way while Terry performed a slam-dunk, during a game at a friend’s birthday party.

The boy was today awake and smiling, still in some pain but in good spirits and expected to make a full recovery, according to plastic surgeon, Mr Robert Love.

“What we have is parts that are very much alive so the reattached limbs are certainly pink, well perfused and are indeed moving,” Mr Love told reporters today.

“The fact that he is moving his fingers, and of course when he wakes up he will move both fingers and toes, is not a surprise,” Mr Love had said yesterday.

“The question is more the sensory return that he will get in the hand itself and the fine movements he will have in the fingers and the toes, and that will come with time, hopefully. We will assess that over the next 18 months to two years.

“I’m sure that he’ll enjoy a game of basketball in the future.”

The weight and force of the collapse, and the sharp brick edges, resulted in the three limbs being cut through about 7cm above the wrists and ankle.

Terry’s father Tan said of his only child, the injuries were terrible, “I was scared to look at him, a horrible thing.”

The hands and foot were placed in an ice-filled Esky and rushed to hospital with the boy, where three teams of medical experts were assembled, and he was given a blood transfusion after experiencing massive blood loss. Eight hours of complex micro-surgery on Saturday night were followed by a further two hours of skin grafts yesterday.

“What he will lose because it was such a large zone of traumatised skin and muscle and so on, he will lose some of the skin so he’ll certainly require lots of further surgery regardless of whether the skin survives,” said Mr Love said today.

The boy was kept unconscious under anaesthetic between the two procedures. In an interview yesterday, Mr Love explained why:

“He could have actually been woken up the next day. Because we were intending to take him back to theatre for a second look, to look at the traumatised skin flaps, to close more of his wounds and to do split skin grafting, it was felt the best thing to do would be to keep him stable and to keep him anaesthetised.”

Professor Wayne Morrison, director of the respected Bernard O’Brien Institute of Microsurgery and head of plastic and hand surgery at Melbourne’s St Vincent’s Hospital, said he believed the operation to be a world first.

Danville, California — The California-based Engligh language tracker, Global Language Monitor, released its 2005 list of most confusing – yet frequently cited – high tech buzzwords to be “HTTP,” “Voice Over IP” (VoIP), and “Megapixel.” Closely following were “Plasma,” “Robust,” “WORM” and “Emoticon.”

In early March, the group used a predictive index computer algorithm to track specific words and phrases in the media and on the Internet. They were tracked in relation to frequency, contextual usage and appearance in global media outlets.

The Global Language Monitor claims to analyze and catalogue trends in word usage and word choices, focusing on the linguistic impact on various cultures. The GLM says it relies upon a global network of volunteer linguists, professional wordsmiths and other bibliophiles to monitor the trends in the evolution and demise of world languages.

GLM’s list, in order of frequency of use, of the most-confusing technology terms with the group’s explanation as to why they are faulty follows:

1. HTTP – HyperText Transfer Protocol is the standard protocol used for transmitting web pages (which are written in HTML (HyperText Markup Language)), not text written while hyper on too much Starbucks coffee. There are more than 1 billion references to HTTP on the web alone.
2. Voice over IP – Voice over Internet Protocol, (pronounced voyp, similar to Detroit) is a way of transmitting voice data over the Internet. VoIP is becoming more popular as services such as Skype offer people free voice communication with anyone with a broad-band connection.
3. Megapixel – Approximately one million pixels, not a single, big pixel (“mega” is the metric system prefix for million). “Pixel” itself is a technical term which means “picture element”. Digital pictures consist of a grid of millions of pixels, which are square or rectangular dots, each having a single colour.
4. Plasma – A plasma display (commonly used in televisions) is a flat, lightweight surface with a grid of millions of tiny glass bubbles containing plasma. A digitally controlled electric current flows through the bubbles causing the plasma inside to glow various colours. Plasma displays have nothing to do with blood plasma.
5. Robust – Robustness generally means “it won’t break easily.” It supposedly describes computer programs or hardware that have been well-tested and demonstrated to not crash or fail often, but since it is a vague term by nature (how robust is robust?) it is frequently used by marketing types regardless.
6. WORM – While a worm is a type of computer virus, WORM stands for ’Write Once, Read Many’. It describes a file system primarily used for optical disks, such as CDs and DVDs. For example, CD-Rs can only be written (or “burned”) once but afterwards can be read many times (otherwise you could only listen to your music CD once). This excludes re-writable CDs which can be written many times.
7. Emoticon – Emoticon stands for emotional icon. An emoticon is a sequence of characters that look visually like a face and are used in text chat to convey emotion. The most common emoticon is the smiley face – 🙂 – which looks like two eyes and a mouth turned 90 degrees.
8. Best of Breed – Not to be confused with the Westminster Dog Show, a best-of-breed product is a personalized solution made of components from various manufacturers; in other words, it’s a sort of high tech ‘mix-and-match’.
9. Viral Marketing – A recent marketing trend which relies on word-of-mouth to spread, rather than traditional advertising strategies. It is called “viral” because as people talk about it, the marketing message “spreads” to new people, who in turn inform others, and so on, which is how viruses spread. The Burger King “Subservient Chicken” campaign is considered an example of viral marketing. Computer viruses used by spammers to turn desktop computers into “zombie” spam relays are something completely different.
10. Data Migration – Data migration is an idealistic (though usually impossible) concept where data can be used by different versions of the program in which it was created (newer or older). The migration (migration means “to move”) refers to the fact that the data is moved from one version (or program) to another without difficulty or loss of information. It is a subset of backward and forward compatibility.

Other terms being tracked included “client/server,” “solution,” “paradigm,” “backward compatible,” and the “STUN protocol.”

Two individuals are in custody after eleven secondary school students were injured in a firearms incident near a school Auchinleck Academy, in East Ayrshire, Scotland, yesterday afternoon. Police have said they are carrying out “extensive enquiries” into the incident, which reportedly involved an air gun or BB gun.

One pupil said he was walking near the school during the lunch hour and “saw two people behind a hedge.” There was a sound “like a small explosion,” he said. “I wasn’t really frightened at first but I’m quite shaken now as I know what damage has been done.”

Strathclyde Police said officers were attending an incident near the secondary school, which has approximately 950 students. Chief Superintendent John Thompson, who is leading the police inquiry into the incident, confirmed two people, aged 15 and 18, were detained in the area of the incident, in which eleven youths were injured.

“Subsequent inquiries directed us towards a house in Auchinleck where we have detained an 18-year-old male and a 15-year-old male,” Thompson said. “Both of those individuals are being interviewed at present and our inquiries are ongoing.” He appealed for people in the area of the incident to contact police.

East Ayrshire council stated “[t]he school responded immediately, informing the police and parents of the children involved, and sought appropriate medical attention”, and added officials were supporting pupils. Auchinleck Academy has not replied to a request for a comment from Wikinews.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.

NASA celebrated the launch of the first space shuttle Tuesday at an event at the Kennedy Space Center (KSC) in Cape Canaveral, Florida. On April 12, 1981, Space Shuttle Columbia lifted off from the Kennedy Space Center on STS-1, the first space shuttle mission.

NASA held a ceremony commemorating the date outside the hangar, known as Orbiter Processing Facility-1, for Space Shuttle Atlantis, which is being prepped for its final mission which will be STS-135, which will be the last Space Shuttle mission.

At the ceremony, NASA Administrator Charles Bolden announced the locations that would be given the three remaining Space Shuttle orbiters following the end of the Space Shuttle program. The prototype orbiter, Space Shuttle Enterprise would be relocated from the Smithsonian’s National Air and Space Museum Steven F. Udvar-Hazy Center at Washington Dulles International Airport to the Intrepid Sea-Air-Space Museum in New York City.

Space Shuttle Discovery will take the place of Enterprise at the Udvar-Hazy Center. Discovery has already been retired following the completion of STS-133 last month, its 39th mission. Discovery is undergoing decommissioning and currently being prepped for display by removing toxic materials from the orbiter.

Space Shuttle Endeavour, which will launch on STS-134 at the end of the month on April 29, will be sent to the California Science Center in Los Angeles, California following its retirement. Finally, Atlantis will go on display at the Kennedy Space Center Visitor Complex following the orbiter’s last flight which launches June 28.

Columbia was lost tragically back on February 1, 2003 when it disintegrated during re-entry killing all seven astronauts aboard. Space Shuttle Challenger was lost when it exploded 73 seconds after liftoff back on January 28, 1986 killing all six aboard.

“We want to thank all of the locations that expressed an interest in one of these national treasures,” said Bolden to the gathered crowd which contained many KSC employees. “This was a very difficult decision, but one that was made with the American public in mind. In the end, these choices provide the greatest number of people with the best opportunity to share in the history and accomplishments of NASA’s remarkable Space Shuttle Program. These facilities we’ve chosen have a noteworthy legacy of preserving space artifacts and providing outstanding access to U.S. and international visitors.”

Over twenty locations looked to obtain one of the orbiters because of potential tourism booms from them.

Not all were pleased with the final choice of locations. U.S. Senator John Cornyn, Republican from Texas, issued a statement regarding the rejection of Johnson Space Center (JSC) in Houston, Texas as a location. “Like many Texans, I am disappointed with NASA’s decision to slight the Johnson Space Center as a permanent home for one of the Space Shuttle Orbiters. Houston has played a critical role throughout the life of the space shuttle, but it is clear political favors trumped common sense and fairness in the selection of the final locations for the orbiter fleet.”

Cornyn’s statement added, “There is no question Houston should have been selected as a final home for one of the orbiters—even Administrator Bolden stated as much. Today’s announcement is an affront to the thousands of dedicated men and women at Johnson Space Center, the greater Houston community and the State of Texas, and I’m deeply disappointed with the Administration’s misguided decision.” However, the JSC will recieve pilot and commander seats from the flight deck.

The Museum of Flight in Seattle, Washington was also proposed as another location for a shuttle, going so far as to build a new building to house an orbiter. In a statement, Governor of Washington Chris Gregoire said, “The Museum of Flight put a tremendous amount of effort into landing a retired shuttle in the Pacific Northwest. As the home of modern day air travel and the 747, which has gracefully transported shuttles for the last 30 years, Seattle would have been a perfect fit. While the Museum of Flight was in the top running, I’m disappointed that NASA did not choose them.

“However, the full fuselage trainer, that every astronaut including [former Museum of Flight CEO] Bonnie Dunbar has been trained on, will soon call the Museum of Flight home. The largest of the trainers, this addition will allow visitors to actually climb aboard the trainer and experience the hands-on training that astronauts get. Visitors will not be allowed in the other shuttles and this trainer is a true win for our dynamic museum. It will help inspire young people to the adventure of space and to the excitement of a career in science, technology, engineering and math.”

Other items include various shuttle simulators which will be given to the Adler Planetarium in Chicago, Illinois, the Evergreen Aviation & Space Museum of McMinnville, Oregon, and Texas A&M’s Aerospace Engineering Department. The nose cap assembly and crew compartment trainer for the National Museum of the U.S. Air Force at Wright-Patterson Air Force Base in Ohio and orbital maneuvering system engines for the U.S. Space and Rocket Center in Huntsville, Alabama, the National Air and Space Museum, and the Evergreen Aviation & Space Museum.

NASA is also offering shuttle heat shield tiles to schools and universities that want to share technology and a piece of space history with their students.

The 30th anniversary of the first shuttle mission coincided with the 50th anniversary of the first manned space flight when Yuri Gagarin lifted off aboard Vostok 1 into space.
