A Scottish woman who set out before Christmas to purchase a turkey finally made it home on Monday, after being cut off by snow for a month. Kay Ure left the Lighthouse Keeper’s cottage on Cape Wrath, at the very northwest tip of Great Britain, in December. She was heading to Inverness on a shopping trip.

However on her return journey heavy snow and ice prevented her husband, John, from travelling the last 11 miles to pick her up. She was forced to wait a month in a friend’s caravan, before the weather improved and the couple could finally be reunited.

They were separated not just for Christmas and New Year, but also for Mr Ure’s 58th birthday. With no fresh supplies, he was reduced to celebrating with a tin of baked beans. He also ran out of coal, and had to feed the couple’s six springer spaniels on emergency army rations.

“It’s the first time we’ve been separated”, said Mr Ure in December. “We’ve been snowed in here for three weeks before, so we are well used to it and it’s quite nice to get a bit of peace and quiet.”

Today saw Edinburgh’s Scottish National Portrait Gallery reopen following a two-and-a-half-year, £17.6m (US$27.4m) refurbishment. Conversion of office and storage areas sees 60% more space available for displays, and the world’s first purpose-built portrait space is redefining what a portrait gallery should contain; amongst the displays are photographs of the Scottish landscape—portraits of the country itself.

First opened in 1889, Sir Robert Rowand Anderson’s red sandstone building was gifted to the nation by John Ritchie Findlay, then-owner of The Scotsman newspaper and, a well-known philanthropist. The original cost of construction between 1885 and 1890 is estimated at over 70,000 pounds sterling. Up until 1954, the building also housed the Society of Antiquaries of Scotland who moved to the National Museum of Scotland buildings on Chambers Street. The society’s original meeting table now sits in the public part of the portrait gallery’s library, stared down on by an array of busts and phrenological artefacts.

Wikinewsie Brian McNeil, with other members of the press, received a guided tour of the gallery last Monday from Deputy Director Nicola Kalinsky. What Kalinsky described as an introduction to the gallery that previously took around 40 minutes, now takes in excess of an hour-and-a-half; with little in the way of questions asked, a more inquisitive tour group could readily take well over two hours to be guided round the seventeen exhibitions currently housed in the gallery.

A substantial amount of the 60% additional exhibition space is readily apparent on the ground floor. On your left as you enter the gallery is the newly-fitted giant glass elevator, and the “Hot Scots” photographic portrait gallery. This exhibit is intended to show well-known Scottish faces, and will change over time as people fall out of favour, and others take their place. A substantial number of the people now being highlighted are current, and recent, cast members from the BBC’s Doctor Who series.

The new elevator (left) is the most visible change to improve disabled access to the gallery. Prior to the renovation work, access was only ‘on request’ through staff using a wooden ramp to allow wheelchair access. The entire Queen Street front of the building is reworked with sloping access in addition to the original steps. Whilst a lift was previously available within the gallery, it was only large enough for two people; when used for a wheelchair, it was so cramped that any disabled person’s helper had to go up or down separately from them.

The gallery expects that the renovation work will see visitor numbers double from before the 2009 closure to around 300,000 each year. As with many of Edinburgh’s museums and galleries, access is free to the public.

The expected significant increase in numbers has seen them working closely with the National Museum of Scotland, which was itself reopened earlier this year after extensive refurbishment work; improved access for wheelchair users also makes it far easier for mothers with baby buggies to access the gallery – prompting more thought on issues as seemingly small as nappy-changing – as Patricia Convery, the gallery’s Head of Press, told Wikinews, a great deal of thought went into the practicalities of increased visitor numbers, and what is needed to ensure as many visitors as possible have a good experience at the gallery.

Press access to the gallery on Monday was from around 11:30am, with refreshments and an opportunity to catch some of the staff in the Grand Hall before a brief welcoming introduction to the refurbished gallery given by John Leighton, director of the National Galleries of Scotland. Centre-stage in the Grand Hall is a statue of Robert Burns built with funds raised from around the British Empire and intended for his memorial situated on Edinburgh’s Calton Hill.

The ambulatories surrounding the Grand Hall give the space a cathedral-like feel, with numerous busts – predominantly of Scottish figures – looking in on the tiled floor. The east corner holds a plaque commemorating the gallery’s reopening, next to a far more ornate memorial to John Ritchie Findlay, who not only funded and commissioned the building’s construction, but masterminded all aspects of the then-new home for the national collection.

Split into two groups, members of the press toured with gallery Director James Holloway, and Nicola Kalinsky, Deputy Director. Wikinews’ McNeil joined Kalinsky’s group, first visiting The Contemporary Scotland Gallery. This ground-floor gallery currently houses two exhibits, first being the Hot Scots display of photographic portraits of well-known Scottish figures from film, television, and music. Centre-stage in this exhibit is the newly-acquired Albert Watson portrait of Sir Sean Connery. James McAvoy, Armando Iannucci, playwright John Byrne, and Dr Who actress Karen Gillan also feature in the 18-photograph display.

The second exhibit in the Contemporary gallery, flanked by the new educational facilities, is the Missing exhibit. This is a video installation by Graham Fagen, and deals with the issue of missing persons. The installation was first shown during the National Theatre of Scotland’s staging of Andrew O’Hagan’s play, The Missing. Amongst the images displayed in Fagen’s video exhibit are clips from the deprived Sighthill and Wester-Hailes areas of Edinburgh, including footage of empty play-areas and footbridges across larger roads that sub-divide the areas.

With the only other facilities on the ground floor being the education suite, reception/information desk, cafe and the gallery’s shop, Wikinews’ McNeil proceeded with the rest of Kalinsky’s tour group to the top floor of the gallery, all easily fitting into the large glass hydraulic elevator.

The top (2nd) floor of the building is now divided into ten galleries, with the larger spaces having had lowered, false ceilings removed, and adjustable ceiling blinds installed to allow a degree of control over the amount of natural light let in. The architects and building contractors responsible for the renovation work were required, for one side of the building, to recreate previously-removed skylights by duplicating those they refurbished on the other. Kalinsky, at one point, highlighted a constructed-from-scratch new sandstone door frame; indistinguishable from the building’s original fittings, she remarked that the building workers had taken “a real interest” in the vision for the gallery.

The tour group were first shown the Citizens of the World gallery, currently hosting an 18th century Enlightenment-themed display which focuses on the works of David Hume and Allan Ramsay. Alongside the most significant 18th century items from the National Portrait Gallery’s collection, are some of the 133 new loans for the opening displays. For previous visitors to the gallery, one other notable change is underfoot; previously carpeted, the original parquet floors of the museum have been polished and varnished, and there is little to indicate it is over 120 years since the flooring was originally laid.

Throughout many of the upper-floor displays, the gallery has placed more light-sensitive works in wall-mounted cabinets and pull-out drawers. Akin to rummaging through the drawers and cupboards of a strange house, a wealth of items – many previously never displayed – are now accessible by the public. Commenting on the larger, featured oils, Deputy Director Kalinsky stressed that centuries-old portraits displayed in the naturally-lit upper exhibitions had not been restored for the opening; focus groups touring the gallery during the renovation had queried this, and the visibly bright colours are actually the consequence of displaying the works in natural light, not costly and risky restoration of the paintings.

There are four other large galleries on the top floor. Reformation to Revolution is an exhibition covering the transition from an absolute Catholic monarchy through to the 1688 revolution. Items on-display include some of the Scottish National Portrait Gallery’s most famous items – including Mary Queen of Scots and The Execution of Charles I. The portrait-based depiction of this historical age is complemented with prints, medals, and miniatures from the period.

Imagining Power is a Jacobite-themed exhibition, one which looks at the sometime-romanticised Stuart dynasty. The Gallery owns the most extensive collection of such material in the world; the portraiture that includes Flora MacDonald and Prince Charles Edward Stuart is complemented by glassware from the period which is on-loan from the Drambuie Liqueur Company which Kalinsky remarked upon as the only way Scots from the period could celebrate the deposed monarchy – toasting The King over the Water in appropriately engraved glasses.

On the other side of the upper floor, the two main naturally-lit exhibitions are The Age of Improvement, and Playing for Scotland. The first of these looks at societal changes through the 18th and 19th centuries, including Nasmyth’s 1787 portrait of the young Robert Burns and – well-known to past visitors to the portrait gallery – Raeburn’s 1822 depiction of Sir Walter Scott. These are complemented with some of the National Gallery’s collection of landscapes and earliest scenes from Scottish industry.

Playing for Scotland takes a look at the development of modern sports in the 19th century; migration from countryside to cities dramatically increased participation in sporting activities, and standardised rules were laid down for many modern sports. This exhibition covers Scotland’s four national sports – curling, shinty, golf, and bowls – and includes some interesting photographic images, such as those of early strong-men, which show how more leisure time increased people’s involvement in sporting activities.

Next to the Reformation to Revolution gallery is A Survey of Scotland. Largely composed of works on-loan from the National Library of Scotland, this showcase of John Slezer’s work which led to the 1693 publication of Theatrum Scotiae also includes some of the important early landscape paintings in the national collection.

The work of Scotland’s first portrait painter, the Aberdeen-born George Jamesone, takes up the other of the smaller exhibits on the east side of the refurbished building. As the first-ever dedicated display of Jamesone’s work, his imaginary heroic portraits of Robert the Bruce and Sir William Wallace are included.

On the west side of the building, the two smaller galleries currently house the Close Encounters and Out of the Shadow exhibits. Close Encounters is an extensive collection of the Glasgow slums photographic work of Thomas Annan. Few people are visible in the black and white images of the slums, making what were squalid conditions appear more romantic than the actual conditions of living in them.

The Out of the Shadow exhibit takes a look at the role of women in 19th century Scotland, showing them moving forward and becoming more recognisable individuals. The exceptions to the rules of the time, known for their work as writers and artists, as-opposed to the perceived role of primary duties as wives and mothers, are showcased. Previously constrained to the domestic sphere and only featuring in portraits alongside men, those on-display are some of the people who laid the groundwork for the Suffrage movement.

The first floor of the newly-reopened building has four exhibits on one side, with the library and photographic gallery on the other. The wood-lined library was moved, in its entirety, from elsewhere in the building and is divided into two parts. In the main public part, the original table from the Society of Antiquaries sits centred and surrounded by glass-fronted cabinets of reference books. Visible, but closed to public access, is the research area. Apart from a slight smell of wood glue, there was little to indicate to the tour group that the entire room had been moved from elsewhere in the building.

The War at Sea exhibit, a collaboration with the Imperial War Museum, showcases the work of official war artist John Lavery. His paintings are on-display, complemented by photographs of the women who worked in British factories throughout the First World War. Just visible from the windows of this gallery is the Firth of Forth where much of the naval action in the war took place. Situated in the corner of the room is a remote-controlled ‘periscope’ which allows visitors a clearer view of the Forth as-seen from the roof of the building.

Sir Patrick Geddes, best-known for his work on urban planning, is cited as one of the key influencers of the Scottish Renaissance Movement which serves as a starting point for The Modern Scot exhibit. A new look at the visual aspects of the movement, and a renewal of Scottish Nationalist culture that began between the two World Wars, continuing into the late 20th century, sees works by William McCance, William Johnstone, and notable modernists on display.

Migration Stories is a mainly photographic exhibit, prominently featuring family portraits from the country’s 30,000-strong Pakistani community, and exploring migration into and out of Scotland. The gallery’s intent is to change the exhibit over time, taking a look at a range of aspects of Scottish identity and the influence on that from migration. In addition to the striking portraits of notable Scots-Pakistani family groups, Fragments of Love – by Pakistani-born filmmaker Sana Bilgrami – and Isabella T. McNair’s visual narration of a Scottish teacher in Lahore are currently on-display.

The adjacent Pioneers of Science exhibit has Ken Currie’s 2002 Three Oncologists as its most dramatic item. Focussing on Scotland’s reputation as a centre of scientific innovation, the model for James Clerk Maxwell’s statue in the city’s George Street sits alongside photographs from the Roslin Institute and a death mask of Dolly the sheep. Deputy Director Kalinsky, commented that Dolly had been an incredibly spoilt animal, often given sweets, and this was evident from her teeth when the death mask was taken.

Now open daily from 10am to 5pm, and with more of their collection visible than ever before, the Scottish National Portrait Gallery will change some of the smaller current exhibits after 12 to 18 months on display. The ground-floor information desk has available five mini-guides, or ‘trails’, which are thematic guides to specific display items. These are: The Secret Nature trail, The Catwalk Collection trail, The Situations Vacant trail, The Best Wee Nation & The World trail, and The Fur Coat an’ Nae Knickers Trail.

A small aircraft struck an apartment building in New York this afternoon, killing the pilot and a flight instructor. Cory Lidle, a pitcher for the New York Yankees baseball team, was the registered owner of the aircraft and is believed to have been piloting it; his passport was found on the scene. The flight instructor was Tyler Stanger.

The plane, a Cirrus SR20 with registration number N929CD, hit the 26th floor of the Belaire Condominium, a 50 story brick luxury residential building on the Upper East Side at 524 East 72nd Street at York Avenue near the East River in Manhattan, New York City, of which the first 20 floors are a hospital. An eyewitness, present half a block from the building, reported that the plane hit the building, creating an enormous fireball, broke in two and crashed down onto on the street below. Authorities received a 911 call reporting a crash at 2:42 p.m. Eastern time.

New York City mayor Michael Bloomberg gave a press conference at approximately 5:20 p.m. Eastern time to report that the plane was occupied by a flight instructor and a student pilot, but as next-of-kin had not been able to be notified, the identities of the two people on the plane would not be released at this time.

Apartments were seen to be engulfed in flames. The FBI has stated that it was not an intentional attack. The New York area was grey and overcast during the time at crash; however, visibility was not hampered.

After an hour and a half, the fire was extinguished by the FDNY. According to CNN Television ten people have been injured, six of them firefighters. The New York Times, however, reports that eleven firefighters have been injured.

Initial reports suggested that a helicopter was involved, but the FAA has stated that it was a fixed-wing aircraft. CNN Television reported that it was a single-engine fixed-wing plane which left Teterboro Airport, a busy General Aviation airport in New Jersey, circled the Statue of Liberty was tracked on radar until it was lost near the 59th Street Bridge, that the plane may have been having fuel problems or fuel pump problems, and that it was “a pilot in distress.”

Wallace Sines, a source for CNN stated he believes the plane was a Cirrus SR-20 with an installed parachute, which did not deploy. The whole-plane parachute system may have saved the lives of the aircraft occupants had it been safely deployed clear of buildings, but the system is not designed to prevent the trauma associated with a plane impacting a builing. The Cirrus SR-20 was introduced in 2001 and the Cirrus line of 4-seater aircraft has since become one of the most purchased single engine aircraft in the world. The SR-20 does not normally carry an airline-style flight-data recorder, but some are equipped with GPS equipment which logs flight direction, speed and altitude.

The aircraft was owned by baseball player Cory Lidle. He was on board reported by AP. Lidle was killed, according to reports. CNN Television reported that the FBI stated he was at the controls as the only occupant of the plane, and that his passport was found on the ground below the accident.

A little over an hour and a half after the crash, the fire was extinguished after 39 fire units and over 100 fire fighters responded.

The White House has said that there has been no change in the terror threat alert level and that President Bush is being updated constantly.

La Guardia airport was temporarily restricted to no take offs from other airports, however by 4:10 Eastern Time, CNN Television reported that all New York-area airports were open.

CNN Television announced at 3:50 p.m. Eastern Time that as of a few minutes earlier, NORAD is putting fighter aircraft on patrol over certain major American cities as a precautionary measure similar to the actions taken after the 9/11 attacks as a “just in case” measure. It also reported that tomorrow is the 6th anniversary of the attack on the USS Cole in Aden, Yemen.

Moments after the crash, there was a drop in the New York Stock Exchange, however it quickly returned to normal after it was reported that the crash was an accident.

The New York Yankees organization confirmed the plane is registered to Cory Lidle of the New York Yankees, who was planning to fly from New York to Florida, and that some unnamed member of the Yankees organization was on the plane.

One eye-witness interviewed by the BBC stated: “I was wondering why the plane was doing acrobatics and then the next thing I knew was that it had crashed into the building.”She also added that the plane was a small, white, 4-seater winged aircraft and not a helicopter as many news agencies were reporting it to be.

CNN Television broadcast reports from eyewitnesses who reported:

• A pilot who saw the impact stated, “It looked like a pilot who was desperately trying to get to an airport.”
• Another eyewitness who saw the event from the Brooklyn-Queens Expressway, also referred to the incident as appearing as if the plane was “desperately trying to get to LaGuardia” and that as to whether he “clipped” the building, or struck it directly, that “he hit it dead on.”
• “I heard a buzzing noise and then an explosion which looked like a mushroom cloud.”

Two activists convicted for painting the words “NO WAR” in five-metre-high red letters on the highest sail of Sydney Opera House in March 2003, are facing court action again to prevent them from auctioning the equipment used to paint the controversial sign.

Dr Will Saunders and David Burgess were sentenced to nine months periodic detention and ordered to pay the Opera House Trust $151,000 for malicious damage to the building on March 18, 2003.

The pair spent six months in jail for painting the slogan on one of the sails of the Opera House on the eve of the invasion of Iraq. The protesters say they wish to auction the equipment for humanitarian causes in Iraq.

Police confiscated the paint can and two brushes used in the incident and have now applied for a court order to have the can and brushes destroyed. They are saying such an auction would contravene proceeds of crime laws.

Saunders said they wanted to auction the can and send the proceeds to humanitarian causes in Iraq. According to The Australian newspaper, Mr Saunders said the auction could be conducted by a registered charity to raise money for the Mother and Child Hospital in Basra.

He said the can should also be preserved as an important piece of Sydney history.

“We want to give the surplus money that we’ve raised, and anything extra we can make from an auction – not only the paint pot … I think we can raise many many thousands of dollars,” he said. “We’d be happy to come to any reasonable arrangement with the police about how this auction takes place … it’s just mean beyond belief, petty-minded just to destroy it.”

The matter will go before a Sydney court on January 16.

Meanwhile, the world-famous Sydney Opera House is one of 21 international landmarks short-listed to become the new Seven Wonders of the World. The list includes modern landmarks such as Paris’ Eiffel Tower and older candidates like the Colosseum in Rome and China’s Great Wall.

Planetary scientist Vlada Stamenkovi? of the NASA Jet Propulsion Laboratory and colleagues have developed a new chemical model of how oxygen dissolves in Martian conditions, which raises the possibility of oxygen-rich brines; enough, the work suggests, to support simple animals such as sponges. The model was published in Nature on October 22. Wikinews caught up with him in an email interview to find out more about his team’s research and their plans for the future.

The atmosphere of Mars is far too thin for humans to breathe or for lungs like ours to extract any oxygen at all. It has on average only around 0.6% of the pressure of Earth’s atmosphere, and this is mainly carbon dioxide; only 0.145% of the thin Martian atmosphere is oxygen. The new model indicated these minute traces of oxygen should be able to enter salty seeps of water on or near the planet’s surface at levels high enough to support life forms comparable to Earth’s microbes, possibly even simple sponges. Some life forms can survive without oxygen, but oxygen permits more energy-intensive metabolism. Almost all complex multicellular life on Earth depends on oxygen.

“We were absolutely flabbergasted […] I went back to recalculate everything like five different times to make sure it’s a real thing,” Stamenkovi? told National Geographic.

“Our work is calling for a complete revision for how we think about the potential for life on Mars, and the work oxygen can do,” he told Scientific American, “implying that if life ever existed on Mars it might have been breathing oxygen”.

Stamenkovi? et al cite research from 2014 showing some simple sponges can survive with only 0.002 moles of oxygen per cubic meter (0.064 mg per liter). Some microbes that need oxygen can survive with as little as a millionth of a mole per cubic meter (0.000032 mg per liter). In their model, they found there can be enough oxygen for microbes throughout Mars, and enough for simple sponges in oases near the poles.

In 2014, also suggesting multicellular life could exist on Mars, de Vera et al, using the facilities at the German Aerospace Center (DLR), studied some lichens, including Pleopsidium chlorophanum, which can grow high up in Antarctic mountain ranges. They showed those lichens can also survive and even grow in Mars simulation chambers. The lichens can do this because their algal component is able to produce the oxygen needed by the fungal component. Stamenkovi? et al’s research provides a way for oxygen to get into the Martian brines without algae or photosynthesis.

Stamenkovi? et al found oxygen levels throughout Mars would be high enough for the least demanding aerobic (oxygen-using) microbes, for all the brines they considered, and all the methods of calculation. They published a detailed map^[3] of the distributions of solubility for calcium perchlorates for their more optimistic calculations, which they reckoned were closer to the true case, with and without supercooling. The lowest concentrations were shown in the tropical southern uplands. Brine in regions poleward of about 67.5° to the north and about 72.5° to the south could have oxygen concentrations high enough for simple sponges. Closer to the poles, concentrations could go higher, approaching levels typical of sea water on Earth, 0.2 moles per cubic meter (6.4 mg per liter), for calcium perchlorates. On Earth, worms and clams that live in the muddy sea beds require 1 mg per liter, bottom feeders such as crabs and oysters 3 mg per liter, and spawning migratory fish 6 mg per liter, all within 0.2 moles per cubic meter, 6.4 mg per liter.

((Wikinews)) Does your paper’s value of up to 0.2 moles of oxygen per cubic meter, the same as Earth’s sea water, mean that there could potentially be life on Mars as active as our sea worms or even fish?

Stamenkovi?: Mars is such a different place than the Earth and we still need to do so much more work before we can even start to speculate.

Stamenkovi? et al studied magnesium and calcium perchlorates, common on Mars. They found the highest oxygen concentrations occur when the water is colder, which happens most in polar regions.

((WN)) The temperatures for the highest levels of oxygen are really low, -133 °C, so, is the idea that this oxygen would be retained when the brines warm up to more habitable temperatures during the day or seasonally? Or would the oxygen be lost as it warms up? Or — is the idea that it has to be some exotic biochemistry that works only at ultra low temperatures like Dirk Schulze-Makuch’s life based on hydrogen peroxide and perchlorates internal to the cells as antifreeze?

Stamenkovi?: The options are both: first, cool oxygen-rich environments do not need to be habitats. They could be reservoirs packed with a necessary nutrient that can be accessed from a deeper and warmer region. Second, the major reason for limiting life at low temperature is ice nucleation, which would not occur in the type of brines that we study.

Stamenkovi? et al’s paper is theoretical and is based on a simplified general circulation model of the Mars atmosphere — it ignores distinctions of seasons and the day / night cycle. Stamenkovi?’s team combined it with a chemical model of how oxygen would dissolve in the brines and used this to predict oxygen levels in such brines at various locations on Mars.

When asked about plans for a future model that might include seasonal timescales, Stamenkovi? told Wikinews, “Yes, we are now exploring the kinetics part and want to see what happens on shorter timescales.”

Stamenkovi? et al’s model also takes account of the tilt of the Mars axis, which varies much more than Earth’s does.

Wikinews asked Stamenkovi? if he had any ideas about whether and how sponges could survive through times when the tilt was higher and less oxygen would be available:

((WN)) I notice from your figure^[4] that there is enough oxygen for sponges only at tilts of about 45 degrees or less. Do you have any thoughts about how sponges could survive periods of time in the distant past when the Mars axial tilt exceeds 45 degrees, for instance, might there be subsurface oxygen-rich oases in caves that recolonize the surface? Also what is the exact figure for the tilt at which oxygen levels sufficient for sponges become possible? (It looks like about 45 degrees from the figure but the paper doesn’t seem to give a figure for this.)

Stamenkovi?: 45 deg is approx. the correct degree. We were also tempted to speculate about this temporal driver but realized that we still know so little about the potential for life on Mars/principles of life that anything related to this question would be pure speculation, unfortunately.

((WN)) How quickly would the oxygen get into the brines — did you investigate the timescale?

Stamenkovi?: No, we did not yet study the dynamics. We first needed to show that the potential is there. We are now studying the timescales and processes.

((WN)) Could the brines that Nilton Renno and his teams simulated, forming on salt/ice interfaces within minutes in Mars simulation conditions, get oxygenated in the process of formation? If not, how long would it take for them to get oxygenated to levels sufficient for aerobic microbes? For instance could the Phoenix leg droplets have taken up enough oxygen for aerobic respiration by microbes?

Stamenkovi?: Just like the answer above. Dynamics is still to be explored. (But this is a really good question ?).

Wikinews also asked Stamenkovi? how their research is linked to the recent discovery of possible large subglacial lake below the Martian South Pole found through radar mapping.

((WN)) Some news stories coupled your research with the subglacial lakes announcement earlier this year. Could the oxygen get through ice into layers of brines such as the possible subglacial lakes at a depth of 1.5 km?

Stamenkovi?: There are other ways to create oxygen. Radiolysis of water molecules into hydrogen and oxygen can liberate oxygen in the deep and that O₂ could be dissolved in deep groundwater. The radiolytic power for this would come from radionuclides naturally contained in rocks, something we observe in diverse regions on Earth.

((WN)) And I’d also like to know about your experiment you want to send to Mars to help with the search for these oxygenated brines.

Stamenkovi?: We are now developing at “NASA/JPL-California Institute of Technology” a small tool, called TH2OR (Transmissive H2O Reconnaissance) that might one day fly with a yet-to-be-determined mission. It will use low frequency sounding techniques, capable of detecting groundwater at depths down to ideally a few km under the Martian surface, thanks to the high electric conductivity of only slightly salty water and Faraday’s law of induction. Most likely, such a small and affordable instrument could be placed stationary on the planet’s surface or be carried passively or actively on mobile surface assets; TH2OR might be also used in combination with existing orbiting assets to increase its sounding depth. Next to determining the depth of groundwater, we should also be able to estimate its salinity and indirectly its potential chemistry, which is critical information for astrobiology and ISRU (in situ resource utilization).

((WN)) Does your TH2OR use TDEM like the Mars 94 mission — and will it use natural ULF sources such as solar wind, diurnal variations in ionosphere heating and lightning?

Stamenkovi?: The physical principle it uses is the same and this has been used for groundwater detection on the Earth for many decades; it’s Faraday’s law of induction in media that are electrically conducting (as slightly saline water is).

Stamenkovi?: However, we will focus on creating our own signal as we do not know whether the EM fields needed for such measurements exist on Mars. However, we will also account for the possibility of already existing fields.

Coinciding with Easter Sunday, Glasgow Cannabis Social Club’s annual 420 event was held on Glasgow Green, under sunny blue skies, and overlooking the river Clyde. Despite the city’s council attempting to revoke permission for the gathering at the last minute, police were happy for it to go-ahead with approximately a dozen officers attending in high-visibility vests.

The Daily Record reported five arrests were made for minor offences, likely smoking and possession of small quantities of cannabis. Taking a less-sensational — and more accurate — line of reporting, the Monday edition of Glasgow’s Evening News stated five were referred to the Procurator Fiscal who is responsible for deciding if charges should be brought.

Official figures provided by the police were that 150 attended. With people coming and going, Wikinews reporters estimated upwards of 200 attended, compared to nearly 700 who had signed up for the event on Facebook. Hemp goods were advertised and on sale at the event, and some attendees were seen drinking cannabis-themed energy drinks.

“I was searched and charged under the Misuse of Drugs Act (which is a lot of bollocks)” one attendee noted online, adding “not fair to happen on a brilliant day like it was, other than that I had a great day!” A second said they were openly smoking and ignored by police, who “were only really focusing on people who looked particularly young”.

Cannabis seeds were openly and legally sold at the event and a hydroponics supplier brought a motortrike towing an advertising trailer. Actually growing cannabis is, however, illegal in the UK.

With the event openly advocating the legalisation of cannabis, speakers put their arguments for this to a receptive crowd. Retired police officer James Duffy, of Law Enforcement Against Prohibition, spoke of the failed United States alcohol prohibition policy; stressing such policies needlessly bring people into contact with criminal elements. Highlighting other countries where legalisation has been implemented, he pointed out such led to lower crime, and lower drug use overall.

One speaker, who produced a bottle of cannabis oil he had received through the post, asserted this cured his prostate cancer. Others highlighted the current use of Sativex by the National Health Service, with a cost in-excess of £150 for a single bottle of GW Pharmaceuticals patented spray — as-compared to the oil shown to the crowd, with a manufacturing cost of approximately £10.

Similar ‘420’ pro-cannabis events were held globally.

In an attempt to speak with as many candidates as possible during the 2008 Canadian federal election, Wikinews has talked via email with David Sparrow. Sparrow is a candidate in Ontario’s Don Valley West riding, running under the New Democratic Party (NDP) banner. The riding was set to vote in a by-election on September 22, 2008, following the resignation of John Godfrey, but Stephen Harper’s sudden election call nulled that effort.

Also running in the Toronto riding are Liberal Rob Oliphant, Conservative John Carmichael, Green Georgina Wilcock, and Communist Catherine Holliday.

The following is an interview with Sparrow, conducted via email. The interview is published unedited, as sent to Wikinews.
