A group of researchers published a paper about their discovery of a new species of Madagascar mermaid skink lizards last December. The species is the fourth forelimbs-only terrestrial tetrapods species known to science, and the first one which also has no fingers on the forelimbs.

The species was collected at Marosely, Boriziny (French: Port-Bergé), Sofia Region, Madagascar. The Sirenoscincus mobydick name is after the existing parent genus, and a sperm whale from the 1851 novel Moby-Dick by Herman Melville.

This week, Wikinews interviewed one of the researchers, French zoologist Aurélien Miralles, about the research.

((Wikinews)) What caused your initial interest in Madagascar lizards?

Aurélien Miralles: Well, I would say that since I am a child I am fascinated by the biodiversity of tropical countries, and more especially by reptiles. I did a PhD on the evolution and systematics of skink lizards from South America. Then, I get a Humboldt grant to do a postdoc in Germany, at the Miguel Vences Lab, in order to study Malagasy skinks. Madagascar being a fabulous hotspot for reptiles (and not only for reptiles actually), it was a very nice opportunity. Professor Vences proposed me to associate our complementary fields of expertise: he is expert in herpetology for Madagascar, and I am expert in skinks lizards (family Scincidae). It was a very fruitful experience, and many other results have still to [be] published.

((WN)) How was the new species discovered?

AM: By a very funny coincidence actually. In 2010, I went to Madagascar for a long trip through the south of the island, in the semi-arid bush for collecting lizards and snakes samples. Then, during the last days, just before coming back to Germany, I have visited by coincidence the zoological collection of the University of Antananarivo. In that place, I found an old jar of ethanol with two weird little specimens previously collected by a student who didn’t realize it was something new. Being expert on skinks, I immediately recognised it was something very probably new, very different from all the other known species.

((WN)) What does “Sirenoscincus” stand for?

AM: I am not the author of the genus name Sirenoscincus. This genus name was already existing. It has been described by Sakata and Hikida (two Japanese herpetologists). “Sireno” means mermaid. “Scincus” means skinks, a group of little lizards on which I am particularly focusing my studies. So, Sirenoscinus means “mermaid skink”, in reference to [the] fact it has forelimbs but no hindlimbs.

((WN)) How deep underground do the lizards live?

AM: Hard to answer this question because nothing is known on the ecology of this species. But more reasonably, we can hypothesize, by comparison to similar species of skinks, that it is probably living just under the sand surface, [a] few centimeters deep, probably no more, or below [a] rock, leaf litter, or piece of dead wood.

((WN)) What do the lizards eat?

AM: Again, by analogy, I would say most likely small invertebrates (insects, larvae, worms etc…).

((WN)) What equipment was used during the research?

AM: Classic equipment (microscope) and also a state-of-the-art device: a micro CT-scan. It is a big device producing [a] 3D picture of the internal structure without damaging the specimen. It is actually very similar to the scanner used in human medicine, but this one is specially designed for small specimens. Otherwise, I am currently studying the DNA of this species and closely related species in order to determine its phylogenetic position compared to other species with legs, in order to learn more about the evolutionary phenomena leading to limb loss.

((WN)) There are several news sources that have a photo of the species. Is it a photo as seen in a CT-scan?

AM: No, this picture showing a whitish specimen on a black background is not a CT-scan. It is a normal photograph of the collection specimen preserved in alcohol (the one that was in the jar). You can see the complete of picture (including CT-scan 3D radiography, drawing…) in the original scientific publication.

((WN)) Do you know when the newly discovered mermaid skink species was put into the jar? Do you have its photo (of the jar)?

AM: No, I have no picture of the jar. The specimen has been collected in November 2004.

((WN)) What were the roles of the people involved in the research? What activity was most time-consuming?

AM: As first investigator, I did most of the work…and the longest part of the work was to examine closely related species in order to do comparisons…and also to check the complete bibliography related to this topic and to write the paper.

Mrs Anjeriniaina is the student who […] collected the specimen a couple of years ago.

Mrs Hipsley and Mr Müller learnt me how to use the CT-scan, and helped me concerning some point relative to internal morphology. Mr Vences helped me as supervisors. Additionally, all of them have corrected the article, and gave me many relevant advices and corrections, thus improving the quality and the reliability of the paper.

((WN)) Did you get in touch with an external entity to get the new species officially recognised?

AM: No. In zoology, it is only needed to publish the description of a new species (and to give it a name) in a scientific journal, and to designate a holotype specimen (= specimen that will be the official reference for this species), to get this new species “officially” recognised by the scientific community. That does not mean that this new species is “correct” (it might be invalidated by subsequent counter-studies), but that means that this discovery and the new name of [the] species are officially existing.

((WN)) Are there any further plans on exploring the species habitat and lifestyle?

AM: No, not really for the time being, because ecology is not our field of expertise. But other studies (including molecular studies) are currently in progress, in order to focus on the phylogenetic position and the evolution of this species.

In an attempt to speak with as many candidates as possible during the 2008 Canadian federal election, Wikinews has talked via email with John Kittredge. John is a candidate in Toronto, Ontario’s St. Paul riding, running under the Libertarian Party banner. Libertarians are a minor, registered political party; they are looking to earn their first ever seat in the House of Commons.

Incumbent Carolyn Bennett of the Liberals is running against Libertarian Kittridge, Conservative Heather Jewell, New Democrat Anita Agrawal, and Justin Erdman, a Green. Bennett was the Minister of Health under previous Prime Minister Paul Martin’s Liberal government. Since it was created in 1935, the riding has been batted about between the Liberals and the now defunct Progessive Conservative party.

The following is an interview with Mr. Kittridge, conducted via email. The interview has had very limited editing, to eliminate in-text mentions of website addresses, but is otherwise left exactly as sent to Wikinews.

A large clinical trial found that grass pollen tablets under the tongue (sublingual) are an effective treatment option for hay fever sufferers. The results have been published in this month’s edition of the Journal of Allergy and Clinical Immunology.

Tablets with grass pollen that dissolve quickly under the tongue may provide doctors with a better tool to fight the illness. The patient could take the pills at his own home, and after a while the symptoms may disappear completely and treatment can be ceased. Contrary to the current standard treatment, this therapy targets the immune system in such a way that it treats the cause and not just the symptoms.

634 patients from 8 countries participated in the trial. Half received Grazax^® tablets (a product of ALK-Abello, Hørsholm, Denmark), the other half placebo pills. The group receiving treatment showed fewer symptoms during hay fever season and consequently cut down on their medication use. Grazax^® also caused few and tolerable side effects such as itching and swelling in the mouth.

Combined with several earlier papers, these results provide a basis for ALK-Abello to apply for European approval of their drug. It has already been approved in Sweden, and the company will follow a Mutual Recognition Procedure hoping to get their product in European pharmacies by the end of 2006. The company will continue to fund further inquiries into Grazax^® and will keep collaborating with scientists from several European countries.

During hay fever season, patients develop a runny nose, swelling of the mucous membranes of the nose, sneezing and teary eyes, a condition doctors call allergic rhinoconjunctivitis. The condition seems to be increasingly frequent, with approximately 10% of the population suffering from grass pollen allergy. First-line treatment includes antihistaminics (like cetirizine or Zyrtec^®/Zyrlex^®) and steroid sprays, but results are often disappointing.

Long term results have been demonstrated for weekly shots with pollen extracts (a procedure called desensitization), but too many visits to the doctor make the process troublesome. Also, the patient has to wait some time before leaving the doctor’s office, due to the risk of developing a kind of shock state termed anaphylactic shock.

Researchers say that new, ten million-year-old fossils found in Ethiopia, prove that the theory that humans may have evolved from a species of great apes eight million years ago, may not be true, but that humans may have split from apes as long as 10.5 million years ago.

At least nine fossilized teeth, one canine tooth and eight molars, of a previously unknown species of apes found in Africa were discovered by a team of researchers from Ethiopia and Japan who then compared the 3-D make up of the teeth to other fossils that date back as far as 8 million years and found that the fossils are likely a “direct ancestor” of apes currently living in Africa and that the new ape fossils were that of a species of gorilla who ate mostly plants high in fiber.

Current fossils and research say that the evolutionary split from apes to humans occurred at least eight million years ago. The new fossils say that the split may have happened as long as 10.5 million years ago.

“Based on this fossil, that means the split is much earlier than has been anticipated by the molecular evidence. That means everything has to be put back,” said researcher at the Rift Valley Research Service in Ethiopia and a co-author of the study, Berhane Asfaw.

Despite the finds, other researchers are not convinced that the findings are correct.

“It is stretching the evidence to base a time scale for the evolution of the great apes on this new fossil. These structures appear on at least three independent lineages of apes, including gorillas, and they could relate to a dietary shift rather than indicating a new genetic trait,” said a Professor at the London Natural History Museum in the United Kingdom, Peter Andrews who also added, “but the fossil evidence for the evolution of our closest living relatives, the great apes, is almost non-existent.

Researchers have named the newly discovered species Cororapithecus abyssinicus whose remains were found in the Afar Region of Ethiopia, the same place where the remains of Lucy were discovered in 1974.

The rescue of the Chilean miners trapped in the San José Mine in Copiapó, codenamed Operación San Lorenzo (San Lorenzo Operation), began on Tuesday night, at around 20:00 local time (23:00 UTC).

Florencio Ávalos was the first miner to be rescued, at 00:12 local time (03:12 UTC) on Wednesday. He was wearing a shirt signed by all his fellow miners. “The first miner is already with us. We saw it all, him hugging his wife Monica and his son Byron,” said President Piñera shortly after the first rescue. “We still have a long journey.”

“This will be recorded on every single Chilean heart forever,” Piñera added. “I hope the miners’ hope stay with us, just like the [February] earthquake victims’ [hope] and what the earthquake took off. We know that the disasters unite us all.”

All the 33 miners were rescued. The last miner, Luis Urzúa, was rescued at 21:55 Chile time (00:55 UTC). “It is a pleasure to be Chilean, [I’m] proud,” said Luis Urzúa to President Piñera. “In honour of the miners, their families, the rescuers […] let’s sing our national anthem. Viva Chile Mierda!,” said Piñera. Urzúa thanked Mining Minister Golborne and the First Lady Cecilia Morel for “fighting for their lives.” “I’m proud of my fellow miners,” Urzúa added.

Six rescuers, including a miner and a paramedic, descended to the miners’ shelter using the Fénix 3 capsule which was specially constructed for the rescue. They performed check-ups and talk with the miners before taking them back to the surface. The rescuers still don’t leave the mine.

The Fénix 3 capsules are 3.95 metres in height and weigh about 460 kilograms. They have an armour, an oxygen tube and a microphone. The occupants helmets contain an intercom to keep them in contact with the rescue team on the surface.

President of Chile Piñera assisted to the rescue. Bolivian President Evo Morales could not attend Carlos Mamani’s rescue. Mamani is the only Bolivian miner in the group.

A mass for the miners was conducted at 18:00 local time (21:00 UTC). The rescue takes between 15 and 20 minutes for each miner.

On Tuesday, Mayor of Copiapó Maglio Cicardini announced that the municipal schools in the city will have no classes this Wednesday “to transform the rescue of the Atacama’s 33 in a familiar meeting,” Radio Cooperativa reported.

“The miners will be taken to the Copiapó Regional Hospital for medical checkup, where they will have to stay for 48 hours,” Health Minister Mañalich said to Televisión Nacional de Chile.

Celebrations are taking place in several Chilean cities. In Santiago de Chile, people gathered in one of the most important points of the city, Plaza Italia. In Pichilemu, tens of cars are passing over its most important streets. In Copiapó, people gathered in its main square to assist a massive concert.

On August 5, 33 miners were trapped more than 700 meters (2,300 ft) underground, in the San José copper–gold mine, located about 40 kilometers north of Copiapó, Chile.

The youngest trapped miner is 19 years old, and the oldest is 63. There were several rescue attempts before reaching the miners’ shelter on August 22. The National Emergencies Office of Chile (ONEMI) released a list of the trapped miners on August 6, which included Franklin Lobos Ramírez, a retired footballer.

Chile is the worlds top producer of copper, according to The Economist. The San José Mine is owned by the San Esteban Mining Company (Empresa Minera San Esteban). The mine was closed down in 2007, after relatives of a miner who had died sued the company executives, but the mine was re–opened in 2008.

It was originally estimated that “it would take three to four months to complete the rescue of the trapped miners”. There were three plans to reach the miners: “Plan A” using a Strata 950 drill, “Plan B” using a Schramm T130XD drill, and “Plan C” using a RIG-422 drill. The first to reach the miners was “Plan B”, early on Saturday 9.

The last step of their rescue, announced by Health Minister Jaime Mañalich, was originally due to begin on Tuesday. Laurence Golborne, Minery Minister said “If it is possible, and the cement sets before and we don’t have any impediments to doing it, it would be wonderful,” in a press conference on Monday. The men will be extracted in a steel rescue capsule 54 cm (21 inches) in diameter.

On September 4, Chilean filmmaker Rodrigo Ortúzar announced plans to film a movie about the accident, called “Los 33” (“The 33”). The film will be released in 2011.

One miner is Bolivian, and the other 32 are Chilean.

Raúl Bustos, 40 years old, is an hydraulics engineer. He left his job in Talcahuano after the February 27 earthquake to work in the mine.

Daniel Herrera, 27 years old, is a lorry driver. He has acted as paramedic assistant in the mine. He said to La Tercera “the miners were unhappy with the psychologist in the rescue team.”

Claudio Acuña, miner, is fan of the Colo-Colo football club. The BBC reports he is aged 56, but El Comercio says he is 44.

Pedro Cortez is aged 24. He joined the mine with his friend Carlos Bugueño. Cortez is an electrician, and lost a finger in the mine a year ago.

The discovery of the presence of airborne asbestos in a middle school in Montclair, New Jersey Friday prompted the evacuation of over 200 students from the school and the school’s closure. Renaissance Middle School, part of the Montclair Public Schools in New Jersey, was closed Monday and remains closed Tuesday while undergoing asbestos testing and cleaning.

According to a letter sent home to parents by the Superintendent’s Office of Montclair Public Schools on Friday, “plaster may have been disturbed” during construction on new fire doors at the Renaissance School building on Thursday.

An inspection arranged by the school district indicated asbestos was present in the plaster, and a subsequent inspection performed by asbestos consultant Detail Associates revealed “a level of airborne asbestos fibers that exceeded the acceptable range” in the third floor hallway of the school. Montclair Public Schools business administrator Dana Sullivan told The Star-Ledger that testing conducted on March 31 revealed the presence of asbestos in a brown undercoating of plaster at the Renaissance School building.

The affected area was sealed off, and some students were moved to other areas of the building while others were moved to off-site locations. District Public Information Officer Laura Federico told The Montclair Times that sixth and seventh graders were transported to Hillside Elementary School, and eighth graders were bussed to Montclair High School. “The safety of our students and staff is always our first concern,” said Federico.

According to The Montclair Times, Detail Associates conducted a cleaning protocol at the school on Saturday and tested the building to make sure it did not contain unacceptable levels of asbestos fibers. The letter sent to parents Friday by the Superintendent’s Office said that Detail Associates had told the district that the building would be “cleaned, tested and cleared for occupancy by Monday morning”. The school remained closed Monday, and a meeting was held between parents and school district officials. A Parent-Teacher Association meeting is planned for Wednesday night.

The Star-Ledger reported that the ongoing asbestos cleanup of the school is being supervised by the state Department of Environmental Protection. At the meeting Monday morning between parents and school district officials, parents demanded that the inside of lockers be included as part of the asbestos cleanup. This additional step in the asbestos inspection process prompted the school’s closure Tuesday. A Monday statement by the Business Office of Montclair Public Schools said that the Renaissance School would remain closed Tuesday for sixth and seventh grade students “so that an extensive cleanup and additional asbestos testing can be completed”. Eighth grade students did not have classes scheduled as a trip to Washington, D.C. had previously been planned; the school trip is unaffected by the recent asbestos incident.

Steve Jaraczewski of Detail Associates was present at the district meeting Monday, and said that one of four test samples taken at the school was positive for the presence of airborne asbestos at over six times acceptable levels. Jaraczewski was critical of the asbestos management plan provided by Roman Catholic Archdiocese of Newark, which owns the school’s building and leases it to Montclair Public Schools.

Jaraczewski said that the state Department of Environmental Protection has required asbestos management plans since 1988, but that the company that drafted the asbestos plan for the Archdiocese of Newark is out of business. Representative for the archdiocese Jim Goodness emphasized that the building would be back open for classes soon. “The kids will be able to go back to school soon, and that’s the important part,” said Goodness.

Exposure to airborne asbestos can lead to mesothelioma, a cancer which develops in the sac surrounding the lungs and chest cavity, abdominal cavity, or the sac surrounding the heart. Exposure to disturbed asbestos fibers can also lead to lung scarring, a condition called asbestosis, and lung cancer. Patients with malignant mesothelioma generally do not have positive outcomes, and once diagnosed have six months to a year to live.

As many as 3,200 mine workers became trapped in the in Elandsrand mine, a gold mine in South Africa about 50 miles (80 km) west of Johannesburg in Carletonville, Gauteng, after an incident on October 3. All miners have been rescued, and none of them were injured. The mine is owned by Harmony Gold Mining Corporation.

The mining company says that a lift electrical cable broke on a basket that was carrying miners, trapping thousands at least 2,200 meters (1.3 miles) below the earth’s surface. Reports from MSNBC and the Guardian Unlimited say that the shaft may have collapsed when a water or air pipe burst. The rescue operation went well with no complications, with the rescue taking just under 24 hours to complete.

“They were underground when the accident happened and they were not able to surface because an electric feeder cable that is connected to the mine lift was severed,” said a spokeswoman for the mining company, Amelia Soares. The snap was caused by a “fatigued” air pipe which burst and fell down the shaft damaging the “steelwork and electrical feeder cords,” added Soares. “They are all in good condition.”

“They are all safe. There have been no injuries or deaths,” said CEO of Harmony mining, Graham Briggs who also said that the miners were previously contacted and were given “food and water.”

Earlier reports had stated that Lesiba Seshoka, a spokesman with the National Union of Mineworkers, said that the miners have not been heard from for hours and that they could have been enduring temperatures as high as 105 degrees Fahrenheit (40 degrees Celsius).

“This is a terrible situation. The only exit is blocked, probably by a fall of ground,” said Seshoka.

Rescue workers used a mine shaft that is next to the damaged one in an attempt to reach the trapped miners, and lifted them out, 75 at a time. There was no emergency exit in the shaft which is reported to have “not been maintained for ages,” added Seshoka.

“An escape route is the most important thing and they have failed miserably. They need to ensure that the shaft is maintained. This is why we have this disaster. Our main worry is for more than 3,000 people who are underground,” said National Union of Mineworkers for S. Africa chairman, Deon Boqwana.

Current reports say that “negligence” was the initial cause for the pipe burst and that there has been a history of negligence from the mine. “We suspect negligence. Because of continuous operations there is no time to make adequate checks,” said the President of the Miners union, Senzeni Zokwana to reporters during a news conference.

The Elsrand mine is currently under development and has been since February 2001 when Harmony bought the mine. Officials state that the mine will remain closed for a minimum of six weeks, while an investigation is performed, and the mine is deemed safe for miners to continue working in it.

The mine is located in the Witwatersrand Basin of South Africa, which is said to be the location of the largest area of raw gold on the planet.
