Cold as ice: Wikinews interviews Marymegan Daly on unusual new sea anemone

Tuesday, January 21, 2014

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.

What fascinates me about sea anemones is that they’re able to do things that seem impossible

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.

Pope Benedict XVI visit to the United States begins

Wednesday, April 16, 2008

Pope Benedict XVI began his visit to the United States on Tuesday. In an unprecedented gesture, he was greeted by President George W. Bush, Laura Bush and their daughter Jenna, upon his arrival at Andrews Air Force Base in Maryland.

Today, which is also the Pope’s 81st birthday, Benedict XVI visited the White House and more than 9,000 people with tickets were there to see him speak. This makes it “one of the largest arrival ceremonies ever held at the White House,” according to White House Press Secretary Dana Perino. An estimated additional 4,000 people without tickets lined the streets.

The Pope was given a 21-gun salute and greeted by President Bush on the South Lawn of the White House. Benedict XVI addressed the crowd in a short speech. He appealed for support “for the patient efforts of international diplomacy to resolve conflicts and promote progress.”

He further said, “As the nation faces the increasingly complex political and ethical issues of our time, I am confident that the American people will find in their religious beliefs a precious source of insight and an inspiration to pursue reasoned, responsible and respectful dialogue in the effort to build a more humane and free society.” Benedict said he has “great respect for this vast pluralistic society” and ended his speech with “God bless America.”

Kevin Waymel, 26, travelled from San Francisco with 80 others to see the Pope. He told The Guardian that he had “come to show support for the Holy Father,” and credited his faith for getting him off drugs.

Afterwards, inside the White House, the first couple presented the Pope with a birthday cake. In a private meeting with Bush, Benedict XVI brought up his concerns about the Iraq war and the treatment of illegal immigrants in the United States, who may number as many as 20 million. Most of these are from Latin America and therefore overwhelmingly Catholic.

After the meeting, Benedict XVI rode along Pennsylvania Avenue in the popemobile with throngs of people lining the street.

Wednesday evening, the Pope met with US bishops at the Basilica of the National Shrine of the Immaculate Conception. He addressed the bishops about sexual abuse by the clergy, which the Pope has said made him “deeply ashamed.” The US Catholic Church has paid out an estimated US$2 billion to settle abuse cases in recent years.

Bendict XVI told the gathered bishops that the sex abuse scandal had at times been mishandled and urged them to reach out to the victims.

“It is your God-given responsibility as pastors to bind up the wounds caused by every breach of trust to foster healing, to promote reconciliation and to reach out with loving concern to those so seriously wronged,” the Pope said.

Some victims had hoped the Pope would have critcised bishops for transferring pedophile priests from parish to parish. He did not go that far and instead praised training programs for priests and lay people who deal with children. “In this regard your efforts to heal and protect are bearing great fruit not only for those directly under your pastoral care, but for all of society,” said Benedict XVI.

“It’s the closest the Pope has come to saying that the bishops didn’t do their job right. I think that’s quite significant,” said the Reverend Thomas J. Reese, a Jesuit priest and author.

Prior to his arrival, hundreds of people were already gathered outside the Basilica as Benedict XVI arrived. “I’m really excited,” said an unnamed onlooker to NY1. “It’s like a dream, almost. There are, like, other foreign dignitaries, and then there’s the pope. It’s a unique experience and I can’t wait to see him.”

During his flight to the United States, Benedict XVI told reporters that he intended to discuss poverty and development aid to poor countries with President Bush. “The United States has to help these countries develop. It is in the interest of everyone, not only these countries but of the world and particularly of the United States,” he said.

This is the first Papal visit to the United States by Benedict XVI, and the first visit of a Pope to the U.S. since John Paul II’s visit in 1999. The pope scheduled to stay in Washington through Thursday. After that, he will travel to New York City where he plans to address the United Nations, visit the World Trade Center site, and celebrate Mass at Yankee Stadium.

UK tabloid Daily Star pays libel damages to Ozzy Osbourne

Saturday, June 7, 2008

The Daily Star, a tabloid newspaper in the United Kingdom, has paid an undisclosed amount of libel damages to Ozzy Osbourne stemming from an inaccurate representation of his appearance at the Brit Awards.

Osbourne, famous for both his solo rock career and fronting the heavy metal band Black Sabbath, was hosting the show alongside wife Sharon and children Jack and Kelly. In an ensuing Star article titled “Ozzy Freak Show”, the 59-year old was portrayed as suffering from health problems that rendered his ability to host the show questionable.

The article claimed that he had collapsed twice before the show began, prompting the show’s organisers to enter emergency talks debating whether Osbourne was fit to continue as planned or instead should be withdrawn and hospitalised. It also reported that the singer had used an electric buggy to move around behind the scenes and had been designated a place to sit in case he felt tired. All of these allegations were found to be false.

At the settlement in London’s High Court, at which the Osbournes were not present, Kate Wilson, representing Express Newspapers, apologised for the article and accepted that it should never have been published. Express Newspapers owns the Daily Star.

Osbourne says that the money will go to his wife’s charity, the Sharon Osbourne Colon Cancer Program.

Step By Step Kitchen Renovation

By Brian Jenkins

The kitchen is the heart of the home, and a kitchen remodeling project is one of the most dramatic, as well as most expensive, projects that you can undertake in your home. Before you begin a kitchen remodeling job, it is important to plan the project from beginning to end. If you neglect this step, it is easy to experience price overruns as well as unexpected structural problems.

Establish a Budget and Design the Space

The most important part of the entire project is to establish a budget. Too often, people decide what they want first, and establish a budget around that. By establishing a budget first, you can choose what you must have, what you would like and what you would settle with in your new kitchen. Everyone’s priorities are different, as is their budget, and there is no right or wrong answer. For some, a natural stone counter top is a priority, while others want to extend the size of the room. Establishing a firm budget and discussing it honestly with your contractor keeps you both on the same page for the duration of the project.

Once you have established a budget, take out some paper and sketch your ideas. Depending on your budget, your contractor, an architect, or the salesman at the local lumber store can give you computer generated plans, but prior to that, sketch your ideas, moving things around, until you are generally happy with your plan.

Empty the Area

Once you have settled on a design, empty everything out of the kitchen. This is a good time to reorganize, getting rid of the small appliances and serving dishes that you never use, as well as cleaning out those drawers and cabinets that inevitably become catch-alls for things without a home.

Complete any Structural Changes

The actual construction starts with any significant structural changes. These may include anything from moving walls, to adding or moving windows or doors. Even if you plan on doing much of the remodeling work on your own, you may consider using a professional contractor for this portion of the job.

Make Necessary Plumbing and Electrical Changes

This is another part of the job that should be completed by a licensed professional. In fact, depending on where you live, you may be required by law to have a professional make any changes to the electrical or plumbing systems in your home. Some changes, such as adding can lights or running an instant hot water tap are relatively straightforward, while others, such as adding wiring for a dishwasher, or running a gas line for a stove, can affect the entire home if not done properly.

This is the time to order cabinets, flooring and your counter top as well as any new appliances you will be purchasing. This ensures that you will have all of your finishing materials ready for installation when the major remodeling work is completed.

Install Flooring and Cabinets

Once you are finished with the major changes, it is time to begin the more exciting finish work. Your new floor and cabinets are ready to be installed. Cabinet installation is best left to professionals, but a do-it-yourselfer can easily install many types of flooring, including hardwood, laminate and tile, on their own. This is a good way to save a little money on your remodel.

Complete Finish Plumbing Work and Paint

The final step in a kitchen renovation is the finish plumbing work and painting. The finish plumbing includes installing the dishwasher as well as the sink and any additional water lines, such as hooking up the refrigerator water line and a hot water tap. Painting is the last step in the kitchen remodeling project. It is much easier to select paint for your new kitchen after the new cabinets, counter top and flooring is in. The look of your kitchen can change so much, even during a minor remodel, that you may not be happy with your paint if you make the selection too early.

Moderation is Okay

While this article explains all of the details that are included in a complete kitchen remodel, it is possible to update your kitchen by completing a less extensive remodeling project. A fresh coat of paint, new appliances or even an updated counter top can increase the appeal of your kitchen and make it a more pleasant place to congregate.

Tips On Choosing New Entry Doors In Prince Georges County, Md

byadmin

When the moment comes to upgrade your home’s Entry Doors in Prince Georges County MD, you should spend some time comparing the different types of doors available in order to determine the type of material your door should be made from.

Your selection of new entry doors will need to be based on more than just how nice they will look. The entry doors to a home can be one of the primary ways to transfer heat between the inside and outside of your home. So, if you wish your home to be as energy efficient as possible, it’s important to make sure that you purchase a door with good insulating features.

Most materials used in constructing entry doors have some insulation, though, which helps to keep the heat in the house during winter and outside during the summer. However, some materials can provide more insulation and other properties designed to make the door more efficient. One of these materials is steel.

Steel entry doors at Master Sealcan be a great choice for Entry Doors in Prince Georges County, MD for a number of reasons. Steel can withstand very harsh conditions and resist a variety of types of weather, and also has a foam core that increases its insulating properties and makes it one of the better choices for an entry door.

In addition, steel doors are also very strong and can assure the safety of those living in the home. Also, steel will not crack or warp, and it’s resistant to fire as well.

You can purchase a steel door in a variety of designs, too. Some are coated in vinyl so they can have a decorative finish in any color the homeowner may wish. However, if you would like the look of wooden doors, a steel door can also be covered with wood veneers to accomplish this look as well.

When looking for a new front door, it’s important to find a door that looks good. It’s also beneficial to find a unit that is energy efficient. For more information, please visit Master Seal Doors

Wheelchair Rugby Tri-Nations Series begins in Sydney

Friday, September 20, 2013

Cathedral Square, Sydney, Australia —Wikinews attended the Wheelchair Rugby Tri-Nations Series in Cathedral Square, Sydney, ongoing from Wednesday. This is the first time an international wheelchair rugby event has been held outdoors, and in this arena. Three nations are competing: the United States, Australia, and New Zealand.

  • 1
  • 2
  • 3
  • 4
  • 5
  • 6

The venue is Cathedral Square, Sydney, which is adjacent to Hyde Park. The Sydney Central Business district is on the other side of the park. An outdoor stadium has been constructed specifically for the tournament, which is believed to be the first time an international wheelchair rugby tournament has been held outdoors. This choice was validated by the fine and warm weather. Free sunscreen was given to the crowd.

The Opening Ceremony was officiated by Australian Paralympic Committee Chief Executive Officer Jason Hellwig. In attendance were the Premier of New South Wales, Barry O’Farrell, the Deputy Lord Mayor of Sydney, Robyn Kemmis, and Paralympic swimmer Matthew Cowdrey. A large crowd, mostly consisting of school groups, was entertained by boy band Justice Crew singing their hit Best Night.

Each team is to play the others two twice, on Wednesday September 18 and Thursday September 19. Finals are to be held on Friday. All three teams are highly ranked internationally. The United States team is ranked number one in the world. It won bronze at the 2004 Summer Paralympics in Athens, gold at the 2008 Summer Paralympics in Beijing, and bronze at the 2012 Summer Paralympics in London, and is the current world champion. This is its first visit to Australia since the 2000 Summer Paralympics.

The Australian team, known as the Steelers, is ranked second in the world. It won silver in Beijing and gold in London. The team is almost unchanged from the one that won in London. Greg Smith has become the assistant coach.

The first game, held immediately after the Opening Ceremony, was between the United States and Australia. The United States proved the better team, forcing errors and turnovers. Three turnovers in the first quarter were especially costly for the Steelers, who lost 56–43.

The second game was held at 17:30 under lights. The crowd was small, but there were a number of New Zealand fans in the crowd, including a few Maori. Two of the New Zealand players are also Maori. The well-disciplined United States team proved too good for the Wheel Blacks as well, who lost 58–40 in an entertaining contest.

The third game was at 19:30, between Australia and New Zealand. The Australians led the whole game, which was nonetheless entertaining to the last. In the dying seconds of the game, Australia’s Ryley Batt shunted a stalling New Zealand player across the line to force him to score, then threw the ball to team mate Chris Bond, who raced for the line at high speed but was beaten by the buzzer. Australia won 61–48.

The New Zealand team, known as the Wheel Blacks, is ranked tenth in the world. It won gold in Athens.

Highlights of the tournament are scheduled to be shown on Foxtel Sports in Australia on September 28 and 29.

Colleges offering admission to displaced New Orleans students/OH-WY

See the discussion page for instructions on adding schools to this list and for an alphabetically arranged listing of schools.

Due to the damage by Hurricane Katrina and subsequent flooding, a number of colleges and universities in the New Orleans metropolitan area will not be able to hold classes for the fall 2005 semester. It is estimated that 75,000 to 100,000 students have been displaced. [1]. In response, institutions across the United States and Canada are offering late registration for displaced students so that their academic progress is not unduly delayed. Some are offering free or reduced admission to displaced students. At some universities, especially state universities, this offer is limited to residents of the area.

Electronic voting disputed in France

Wednesday, April 18, 2007

In France, voting has traditionally been a low-tech experience: voters isolate themselves in a booth, put a pre-printed sheet of paper indicating their candidate of choice into an envelope. After officials verify the voter’s identity, the voter drops the envelope into the ballot box and signs the voting roll. French electoral law rather strictly codifies the proceedings. Since 1988, ballot boxes must be transparent so that voters and observers can witness that no envelopes are present at the start of the vote and that no envelopes are added except those of the duly counted and authorized voters. Candidates can send representatives to witness every part of the process. In the evening, votes are counted by volunteers under heavy supervision, following specific procedures.

In the past, voting machines, though authorized by law, were scarce. But this year, during presidential elections (the first round was April 22, the second is on May 6), the country is shaken by controversy about the machines intended to count about 1.5 million votes.

As in the United States, there is a group of academic computer scientists that oppose voting machines. They argue that voting machines replace a public, easily understandable counting process, where large-scale fraud would entail large-scale corruption, by an opaque process where votes are counted by machines that voters have to blindly trust. Voting machines have to be approved by the Ministry of the Interior, but this approval is based on confidential reports by private companies. Opponents to the machines point out that the Ministry was long held by Nicolas Sarkozy, who happens to be the leading candidate. Opponents also list a number of weaknesses and discrepancies that have occurred in other countries using voting machines.

All main political parties except UMP, Mr Sarkozy’s ruling party, oppose the voting machines. Some citizens have filed for court injunctions against the voting machines. Opponents have given detailed instructions that voting witnesses should check whether the machines correspond exactly to an approved type, including software versions, and fulfill all legal conditions. In a sign of the frenzy over the issue, on April 12 the Ministry of the Interior issued a last-minute authorization for a specific model (hardware, firmware). The stakes are high: votes on unapproved machines should be canceled by the Constitutional Council for the official count.

The opposition has crystallized on the Paris suburb of Issy-les-Moulineaux. Issy’s mayor, André Santini is a well-known technophile; his city organizes a “World E-Gov Forum”. Here too, last minute fixes are at work. The machines delivered to the city are of a yet-to-be-approved type. The manufacturer, the American company ES&S voting systems, is now delivering older 2005 machines. Le Monde reports that other municipalities have already replaced their recent machines by an older, approved, model.

Proponents of the machines, such as the French company France Élection, claim they are being defamed and dispute the competence of their critics. Elected officials supporting the machines claim the machines save on paper, time, and the need to find volunteers to count votes.
