In late 2010 a geological expedition to Antarctica drilled through the Ross Ice Shelf so they could send an ROV under it. What they found was unexpected: Sea anemones. In their thousands they were doing what no other species of sea anemone is known to do — they were living in the ice itself.

Discovered by the ANDRILL [Antarctic Drilling] project, the team was so unprepared for biological discoveries they did not have suitable preservatives and the only chemicals available obliterated the creature’s DNA. Nonetheless Marymegan Daly of Ohio State University confirmed the animals were a new species. Named Edwardsiella andrillae after the drilling project that found it, the anemone was finally described in a PLOS ONE paper last month.

ANDRILL lowered their cylindrical camera ROV down a freshly-bored 270m (890ft) hole, enabling it to reach seawater below the ice. The device was merely being tested ahead of its planned mission retrieving data on ocean currents and the sub-ice environment. Instead it found what ANDRILL director Frank Rack of the University of Nebraska–Lincoln, a co-author of the paper describing the find, called the “total serendipity” of “a whole new ecosystem that no one had ever seen before”.

The discovery raises many questions. Burrowing sea anemones worm their way into substrates or use their tentacles to dig, but it’s unclear how E. andrillae enters the hard ice. With only their tentacles protruding into the water from the underneath of the ice shelf questions also revolve around how the animals avoid freezing, how they reproduce, and how they cope with the continuously melting nature of their home. Their diet is also a mystery.

E. andrillae is an opaque white, with an inner ring of eight tentacles and twelve-to-sixteen tentacles in an outer ring. The ROV’s lights produced an orange glow from the creatures, although this may be produced by their food. It measures 16–20mm (0.6–0.8in) but when fully relaxed can extend to triple that.

Genetic analysis being impossible, Daly turned to dissection of the specimens but could find nothing out of the ordinary. Scientists hope to send a biological mission to explore the area under the massive ice sheet, which is in excess of 600 miles (970km) wide. The cameras also observed worms, fish that swim inverted as if the icy roof was the sea floor, crustaceans and a cylindrical creature that used appendages on its ends to move and to grab hold of the anemones.

NASA is providing funding to aid further research, owing to possible similarities between this icy realm and Europa, a moon of Jupiter. Biological research is planned for 2015. An application for funding to the U.S. National Science Foundation, which funds ANDRILL, is also pending.

The ANDRILL team almost failed to get any samples at all. Designed to examine the seafloor, the ROV had to be inverted to examine the roof of ice. Weather conditions prevented biological sampling equipment being delivered from McMurdo Station, but the scientists retrieved 20–30 anemones by using hot water to stun them before sucking them from their burrows with an improvised device fashioned from a coffee filter and a spare ROV thruster. Preserved on-site in ethanol, they were taken to McMurdo station where some were further preserved with formaldehyde.

((Wikinews)) How did you come to be involved with this discovery?

Marymegan Daly: Frank Rack got in touch after they returned from Antarctica in hopes that I could help with an identification on the anemone.

((Wikinews)) What was your first reaction upon learning there was an undiscovered ecosystem under the ice in the Ross Sea?

MD I was amazed and really excited. I think to say it was unexpected is inaccurate, because it implies that there was a well-founded expectation of something. The technology that Frank and his colleagues are using to explore the ice is so important because, given our lack of data, we have no reasonable expectation of what it should be like, or what it shouldn’t be like.

((Wikinews)) There’s a return trip planned hopefully for 2015, with both biologists and ANDRILL geologists. Are you intending to go there yourself?

MD I would love to. But I am also happy to not go, as long as someone collects more animals on my behalf! What I want to do with the animals requires new material preserved in diverse ways, but it doesn’t require me to be there. Although I am sure that being there would enhance my understanding of the animals and the system in which they live, and would help me formulate more and better questions about the anemones, ship time is expensive, especially in Antarctica, and if there are biologists whose contribution is predicated on being there, they should have priority to be there.

((Wikinews)) These animals are shrouded in mystery. Some of the most intriguing questions are chemical; do they produce some kind of antifreeze, and is that orange glow in the ROV lights their own? Talk us through the difficulties encountered when trying to find answers with the specimens on hand.

MD The samples we have are small in terms of numbers and they are all preserved in formalin (a kind of formaldehyde solution). The formalin is great for preserving structures, but for anemones, it prevents study of DNA or of the chemistry of the body. This means we can’t look at the issue you raise with these animals. What we could do, however, was to study anatomy and figure out what it is, so that when we have samples preserved for studying e.g., the genome, transcriptome, or metabolome, or conduct tests of the fluid in the burrows or in the animals themselves, we can make precise comparisons, and figure out what these animals have or do (metabolically or chemically) that lets them live where they live.

Just knowing a whole lot about a single species isn’t very useful, even if that animal is as special as these clearly are — we need to know what about them is different and thus related to living in this strange way. The only way to get at what’s different is to make comparisons with close relatives. We can start that side of the work now, anticipating having more beasts in the future.

In terms of their glow, I suspect that it’s not theirs — although luminescence is common in anemone relatives, they don’t usually make light themselves. They do make a host of florescent proteins, and these may interact with the light of the ROV to give that gorgeous glow.

((Wikinews)) What analysis did you perform on the specimens and what equipment was used?

MD I used a dissecting scope to look at the animal’s external anatomy and overall body organization (magnification of 60X). I embedded a few of the animals in wax and then cut them into very thin slices using a microtome, mounted the slices on microscope slides, stained the slices to enhance contrast, and then looked at those slides under a compound microscope (that’s how I got the pictures of the muscles etc in the paper). I used that same compound scope to look at squashed bits of tissue to see the stinging capsules (=nematocysts).

I compared the things I saw under the ‘scopes to what had been published on other species in this group. This step seems trivial, but it is really the most important part! By comparing my observations to what my colleagues and predecessors had found, I figured out what group it belongs to, and was able to determine that within that group, it was a new species.

((Wikinews)) It was three years between recovery of specimens and final publication, why did it take so long?

MD You mean, how did we manage to make it all happen so quickly, right? 🙂 It was about two years from when Frank sent me specimens to when we got the paper out. Some of that time was just lost time — I had other projects in the queue that I needed to finish. Once we figured out what it was, we played a lot of manuscript email tag, which can be challenging and time consuming given the differing schedules that folks keep in terms of travel, field work, etc. Manuscript review and processing took about four months.

((Wikinews)) What sort of difficulties were posed by the unorthodox preservatives used, and what additional work might be possible on a specimen with intact DNA?

MD The preservation was not unorthodox — they followed best practices for anatomical preservation. Having DNA-suitable material will let us see whether there are new genes, or genes turned on in different ways and at different times that help explain how these animals burrow into hard ice and then survive in the cold. I am curious about the population structure of the “fields” of anemones — the group to which Edwardsiella andrillae belongs includes many species that reproduce asexually, and it’s possible that the fields are “clones” produced asexually rather than the result of sexual reproduction. DNA is the only way to test this.

((Wikinews)) Do you have any theories about the strategies employed to cope with the harsh environment of burrowing inside an ice shelf?

MD I think there must be some kind of antifreeze produced — the cells in contact with ice would otherwise freeze.

((Wikinews)) How has such an apparently large population of clearly unusual sea anemones, not to mention the other creatures caught on camera, gone undetected for so long?

MD I think this reflects how difficult it is to get under the ice and to collect specimens. That being said, since the paper came out, I have been pointed towards two other reports that are probably records of these species: one from Japanese scientists who looked at footage from cameras attached to seals and one from Americans who dove under ice. In both of these cases, the anemone (if that’s what they saw) was seen at a distance, and no specimens were collected. Without the animals in hand, or the capability of a ROV to get close up for pictures, it is hard to know what has been seen, and lacking a definitive ID, hard to have the finding appropriately indexed or contextualized.

((Wikinews)) Would it be fair to say this suggests there may be other undiscovered species of sea anemone that burrow into hard substrates such as ice?

MD I hope so! What fascinates me about sea anemones is that they’re able to do things that seem impossible given their seemingly limited toolkit. This finding certainly expands the realm of possible.

Sweden’s first royal wedding since 1976 took place Saturday when Crown Princess Victoria, 32, married her long-time boyfriend and former personal trainer, Daniel Westling, 36. The ceremony took place at Stockholm Cathedral.

Over 1,200 guests, including many rulers, politicians, royals and other dignitaries from across the world, attended the wedding, which cost an estimated 20 million Swedish kronor. Victoria wore a wedding dress with five-metre long train designed by Pär Engsheden. She wore the same crown that her mother, Queen Silvia, wore on her wedding day 34 years previously, also on June 19. Victoria’s father, King Carl XVI Gustaf, walked Victoria down the aisle, which was deemed untraditional by many. In Sweden, the bride and groom usually walk down the aisle together, emphasising the country’s views on equality. Victoria met with Daniel half-way to the altar, where they exchanged brief kisses, and, to the sounds of the wedding march, made their way to the the silver altar. She was followed by ten bridesmaids. The couple both had tears in their eyes as they said their vows, and apart from fumbling when they exchanged rings, the ceremony went smoothly.

Following the ceremony, the couple headed a fast-paced procession through central Stockholm on a horse-drawn carriage, flanked by police and security. Up to 500,000 people are thought to have lined the streets. They then boarded the Vasaorden, the same royal barge Victoria’s parents used in their wedding, and traveled through Stockholm’s waters, accompanied by flyover of 18 fighter jets near the end of the procession. A wedding banquet followed in the in the Hall of State of the Royal Palace.

Controversy has surrounded the engagement and wedding between the Crown Princess and Westling, a “commoner”. Victoria met Westling as she was recovering from bulemia in 2002. He owned a chain of gymnasiums and was brought in to help bring Victoria back to full health. Westling was raised in a middle-class family in Ockelbo, in central Sweden. His father managed a social services centre, and his mother worked in a post office. When the relationship was made public, Westling was mocked as an outsider and the king was reportedly horrified at the thought of his daughter marrying a “commoner”, even though he did so when he married Silvia. Last year, Westling underwent transplant surgery for a congenital kidney disorder. The Swedish public have been assured that he will be able to have children and that his illness will not be passed on to his offspring.

Westling underwent years of training to prepare for his new role in the royal family, including lessons in etiquette, elocution, and multi-lingual small talk; and a makeover that saw his hair being cropped short, and his plain-looking glasses and clothes being replaced by designer-wear.

Upon marrying the Crown Princess, Westling took his wife’s ducal title and is granted the style “His Royal Highness”. He is now known as HRH Prince Daniel, Duke of Västergötland. He also has his own coat-of-arms and monogram. When Victoria assumes the throne and becomes Queen, Daniel will not become King, but assume a supportive role, similar to that of Prince Phillip, the husband of the United Kingdom’s Queen Elizabeth II.

The province of Alberta, Canada is considering legal action against Canadian National Railway for failing to warn that a derailment last week contaminated Wabamun Lake with a hazardous chemical.

The 700,000 litres of heavy Bunker C fuel oil that spilled into the lake asphyxiated birds and killed fish.

In addition, one of the ruptured tanker cars sent 70,000 liters of Imperial Pole Treating Oil into the lake. This oil is a yellow mixture of polycyclic aromatic hydrocarbons and aliphatic hydrocarbons. Naphthalene, a component of this “very toxic material” is suspected of causing skin cancer if touched and lung or other cancers if inhaled.^[1] Inhalation is promoted by actions that cause splashing or foaming. The mineral oil is used in connection with pentachlorophenol for preserving wooden utility poles.

Wabamun Lake is a popular summertime recreational area about 65 kilometers (40 miles) west of Edmonton, Alberta.

The 766-megawatt Keephills power generating plant, one of 3 in Wabamun, was shut down because the coal-fired plant uses water from the lake. Edmonton’s health authority ordered people not to swim, boat or rescue animals in the lake and to stop using its water or any water from nearby wells for cooking, drinking, showering or brushing teeth. These warnings came 3 days after many residents, including children, had been wading into the oil slick without protective clothing to save wildlife injured by the spill and others had been routinely depending on the lakewater for home use. Why the alert was not issued sooner remains under investigation and may result in criminal charges. Canadian National Railway had been informed of the nature of the oil when it was loaded by Imperial Oil Ltd., Canada’s largest petroleum company. Imperial Oil is posting informational updates on a special website [2]. In addition The Wabamun Residents Committee has established an information website [3].

The United States House of Representatives approved a measure on Thursday to impose a heavy tax on bonuses to executives from companies that have been bailed out by the government. The bill was passed by a margin of 328-93.

Under the bill, executives making over US$250,000 a year would be charged a 90% tax on bonuses. The tax would apply to firms that have been given at least $5 billion in aid from the government.

The move comes after recent outrage at American International Group (AIG), which gave out $165 million in bonuses to its top executives after receiving no more than $180 billion in government bailouts. AIG has said that the bonuses had to be given out, as the company was legally required by contract to do so.

Nancy Pelosi, the Speaker of the House, said that the bill was necessary because of the bad judgment shown by firms who received bailouts from the government.

“We must stabilize the financial system in order to strengthen our economy and create jobs. We must also protect the American taxpayer from executives who would use their companies’ second chances as opportunities for private gain. Because they could not use sound judgment in the use of taxpayer funds, these AIG executives will pay the Treasury in the form of this tax,” said Pelosi to reporters following the House vote.

The Senate is expected to vote upon a similar version of the bill. If approved, the differences between the two versions would have to be bridged before it could be signed into law.

On Friday, May 27, 2005, 9 trains on the New York City Subway will make their final run, ending rush-hour skip-stop service on the IRT Broadway-Seventh Avenue Line north of 137th Street-City College. During rush hours, the 9 is a skip-stop supplement to the 1, running the same route but skipping some stops in Upper Manhattan and the Bronx. At the same time, the 1 skips other stops, which are only served by the 9 at rush hours; some stops are served by all trains. This service pattern results in slightly faster trains, but longer waits for those going to or from skipped stations.

9 service was started on December 12, 1988, at first running during rush hours and middays. In the mid-1990s, midday 9 service was dropped.

The J-Z skip-stop services on the BMT Jamaica Line will not be affected, as many passengers ride straight through the skip-stop portion, making the faster service more worthwhile.

New South Wales Police have begun their holiday Operation Safe Arrival holiday road safety campaign overnight. The campaign runs from 12:01AM December 23, 2005 until 11:59PM January 2, 2006.

In an attempt to keep the number of deaths on NSW roads at a minimum police will target speeding, seatbelt, helmet and drunk driving offences. According to the New South Wales Roads and Traffic Authority, 495 people have died on NSW roads between January 1 and December 11. This figure will surely climb over the holiday period.

The RTA has also begun double demerit points for speeding, seatbelt and helmet offences. The double demerit points will run for the same 11 day period as Operation Safe Arrival. The minimum penalty for any double demerit offence is 6 points. Provisional drivers need to be particularly mindful of these as P1 license holders (those who have had a license 12 months or less) can only incur 3 points. P2 license holders (those who have held a license for 12 to 36 months) have 6 and unrestricted license holders have 12.

According to the RTA, 23,624 drivers in the 2003/4 holiday season were issued with fines carrying double demerits and 2,150 motorists had their licenses suspended due to speeding or exceeding their demerit point limit.

The RTA introduced double demerits in 1997 in an attempt to force drivers to be more mindful of speeding, wearing seatbelts and motorcycle helmets. Double demerit points are now introduced over each major holiday period when a large proportion of road-related deaths occur.

Other jurisdictions in Australia which have double demerit points over holiday periods are South Australia, Western Australia, and the Australian Capital Territory.

In the 1970s, she was one of the most popular female vocalists in France, and became well-known internationally. Anne Marie David, from Arles in the south of France, parlayed her initial success from playing Mary Magdalene in the French production of Jesus Christ Superstar into taking home the “grand prix” at the Eurovision Song Contest in 1973. Her winning song, “Tu te reconnaîtras” (You will recognize yourself), became a Europe-wide hit that spring.

At the height of her popularity, David perfomed world tours, and even lived abroad in Turkey for a time. In 1979, she tried once again to win the Eurovision, and placed a respectable third. Her song “Je suis l’enfant soleil” (I’m a child of the sun) became similarly popular across France and in the Francophone nations.

As time went on, however, her place in the French music scene became less certain. Touring the world had taken a personal toll, and David decided to retire from music completely in 1987. However, with the help of her fan base, she was coaxed out of retirement in 2003 and is returning to a part of her life that she tried to leave, but never left her. Celebrating four decades in the music scene, David is looking forward to adventurous new projects and a newfound zest for life.

Anne Marie David corresponded with Wikinews’ Mike Halterman about her eventful career, her personal anecdotes regarding living abroad, her successes in past Eurovision contests and her grievances with the way the show is produced today. This is the second in a series of interviews with past Eurovision contestants, which will be published sporadically in the lead-up to mid-May’s next contest in Moscow.

Gatorland, an Orlando, Florida tourist attraction known for its gator wrestling shows and its conservation programs for alligators, crocodiles, and other reptiles and birds, was heavily damaged by fire on Monday morning, November 6, 2006.

The four-alarm fire was reported at 5:55am EST. The entrance building, which contains the administration offices and the gift shop, was destroyed. The only thing left standing of it was its iconic gator head front gate, whose upper jaw was almost completely charred.

At least four animals — two gators and two snakes, which were being kept near the gift shop — were feared dead. No humans were hurt. The other gators in the public display took refuge in the central pools, and were okay. The birds were in the aviary in the back, and were in no danger.

None of the attraction venues beyond the gift shop, however, were damaged. Gatorland hopes to reopen for tourists in a week, using a temporary entrance.

Orange County Fire Rescue is investigating the cause of the fire.
