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.

Children who spend more time playing with other children are less likely to end up getting childhood cancers, a UK study published today in the British Medical Journal has found. The finding supports the researchers’ theory that reduced exposure to common infections in the first year of life increases the risk of developing acute lymphoblastic leukaemia (ALL).

A total of nearly 10,000 children took part in the study, located in 10 regions across the UK. Amount of time spent in daycare and social activity, during the first year of life, were used to gauge the level of exposure of the infants to common infections such as cold and flu.

Day care in the first year of life for at least two days a week, with at least three other kids, halved a child’s chance of contracting ALL. Those who were rated in the category “any social activity” still had an improvement over the children rated as “no social activity”: they had about 3/4 the chance of getting the disease.

The study describes that effect was “more striking” for acute lymphoblastic leukaemia — a cancer affecting blood and the immune system — than it was for the set of all other cancers. Increasing levels of activity saw decreasing chances of childhood cancers, when compared against children who during their first year had no regular social activity outside the home.

Theories have been around since the 1940s that childhood exposure to infection was related to the development of childhood leukaemia — one, like the working theory of the UK study, said that lack of immune challenge was a factor, another that leukaemia developed as a delayed result of some type of infection.

The research was conducted by the Institute of Cancer Research in London and in Sutton, London School of Hygiene and Tropical Medicine, University of York, Christie Hospital and Central Manchester and Manchester Children’s University Hospitals NHS Trusts, and the University of Edinburgh.

In the 18 months since Andrea Muizelaar was crowned winner of the reality TV series Canada’s Next Top Model, her life has been a complete whirlwind. From working in a dollar store in her hometown of Whitby, Ontario, to modeling haute couture in Toronto, she had reached her dream of becoming a true Top Model.

But at what cost? Unknown to casual television viewers, Muizelaar had been enveloped in the eating disorder anorexia nervosa, which inevitably became too much for her to bear. She gave up modeling and moved back to Whitby, where she sought treatment for her disorder, re-entered college, and now works at a bank. Where is she now? Happy and healthy, she says.

Recently Andrea Muizelaar sat down with Wikinews reporter Mike Halterman in a candid interview that stretched to nearly two hours, as she told all about her hopes and aspirations, her battle with anorexia, and just what really happened on Canada’s Next Top Model.

Yesterday morning, English drummer Ginger Baker died in a hospital at the age of 80. The news came from the Twitter account in his name and was independently confirmed by Associated Press with his daughter Nettie Baker. On September 25, it was reported Baker was hospitalized in critical condition. Baker was widely known as the drummer and co-founder of the rock band Cream, an early supergroup.

Baker, a life-long smoker and former heroin addict, suffered from health problems for years. The list of ailments included hearing loss, osteoarthritis, emphysema and chronic obstructive pulmonary disease, as well as heart problems for which he had surgery in 2016. Although known to have lived his latter years in South Africa, his daughter said he died in Britain without elaborating.

Ginger Baker was born Peter Edward Baker in Lewisham, London, in 1939. His father was killed in combat in 1943 during World War II. Baker — who was reportedly nicknamed Ginger due to his red hair — began playing drums in his teens. In a story he sometimes told, he had a habit of tapping on school desks. When an opportunity arose at a party, his classmates encouraged him to sit down at a drum set. “I’d never sat behind a kit before, but I sat down — and I could play! One of the musicians turned round and said, ‘Bloody hell, we’ve got a drummer’, and I thought, ‘Bloody hell, I’m a drummer’?”, he recalled in a 2009 retelling of the story to the The Independent.

Baker began his career as a drummer in jazz bands. He played with Acker Bilk and Terry Lightfoot. In 1962, when fellow drummer Charlie Watts was leaving Blues Incorporated for The Rolling Stones, Watts recommended Baker to be his replacement. Later, Baker found early success with rhythm and blues band The Graham Bond Organisation where he met bassist Jack Bruce.

In 1966, Baker, Bruce and singer/guitarist Eric Clapton, who was known from The Yardbirds, formed Cream. The rock trio was a massive success, selling tens of millions of records, including the first ever platinum certified album Wheels of Fire. Cream recorded four albums, then in 1968 disbanded with Baker and Bruce having developed a volatile relationship. Clapton and Baker were subsequently in another supergroup Blind Faith with Steve Winwood and Ric Grech. Blind Faith recorded only one studio album but notably played before a crowd of a hundred thousand at a free concert in London’s Hyde Park.

In the 1970s, Baker moved to Nigeria where he established a studio and began playing polo. Here he collaborated with Fela Kuti and worked on Wings’s album Band on the Run with Paul McCartney of The Beatles fame. Later, he recorded with John Lydon’s Public Image Ltd.

Cream was inducted in 1993 into the Rock and Roll Hall of Fame. The band reunited in 2005 for several London and New York concerts. Afterwards he moved to South Africa, and still lived there when the 2012 documentary Beware of Mr. Baker was filmed. Baker’s last recording was 2014’s Why? solo album. Baker retired from live performances in 2016 due to his ill health.

Paul McCartney wrote on Twitter, “Ginger Baker, great drummer, wild and lovely guy. We worked together on the ‘Band on the Run’ album in his ARC Studio, Lagos, Nigeria. Sad to hear that he died but the memories never will.”

“A very sad loss, and my condolences to his family and friends. A loss also for his contribution to music. He was well-grounded in jazz from very early on,” wrote Steve Winwood in a statement. “Beneath his somewhat abrasive exterior, there was a very sensitive human being with a heart of gold. He’ll be missed.”

Mick Jagger of The Rolling Stones also reacted on Twitter, “Sad news hearing that Ginger Baker has died, I remember playing with him very early on in Alexis Korner’s Blues Incorporated. He was a fiery but extremely talented and innovative drummer.”

The New Zealand Government on Thursday announced the creation of a new public holiday, Matariki. Matariki marks the beginning of the M?ori New Year, which coincides with the rising of the star cluster Pleiades, known as Matariki in the M?ori language.

At Waitangi, New Zealand Prime Minister Jacinda Ardern said “This will be a day to acknowledge our nation’s unique, shared identity, and the importance of tikanga M?ori. It’s going to be something very special, and something uniquely New Zealand.” Ardern also said the new holiday would break up the over-4 month gap between public holidays in June and October.

The date of the Matariki holiday is not consistent from year to year, as it follows Maramataka, the M?ori lunar calendar, but would likely always fall on a Monday or Friday according to Ardern. A Matariki advisory group has been established, with M?ori Crown Relations — Te Arawhiti — Minister Kelvin Davis explaining that the purpose of the group is “to provide advice on future dates of the public holiday, how it should be celebrated and to support the development of resources to educate the public on Matariki and the celebrations”. The first Matariki holiday is scheduled for Friday, June 24 of next year.

Ardern’s Labour Party made the Matariki holiday an election promise, and won last year’s general election with a majority. This result was the best for any party since New Zealand’s 1996 adoption of a mixed-member proportional system.

This is not the first attempt to make Matariki a public holiday. In 2009, M?ori Party Member of Parliament Rahui Katene introduced legislation to create a Matariki public holiday. While it was supported by the then-opposition Labour Party, the governing National Party did not support it, and it was defeated with 59 votes in favour and 63 votes against.

Canadian Finance Minister Jim Flaherty announced a five-year program that could reduce taxes by a total C$60 billion.

The planned tax reduction measures include:

• Low-end personal income tax rates would be reduced from 15.5% to 15%, taking retroactive effect to the start of 2007;
• The basic personal exemption, the amount at which income is taxable, is raised from C$8,929 to C$9,600, also backdated to January 2007;
• Business tax rates are expected regularly drop from the current 20.5% to 15% in 2012;
• The Goods and Services Tax that applies to most purchases would be reduced from 6% to 5% as 2008 begins. This rate was previously reduced from 7% July 2006, shortly after Prime Minister Stephen Harper took office.

These measures will be brought before the House of Commons in Ottawa on Wednesday as a confidence motion. In Canada’s minority government situation, opposition parties could defeat these measures and likely prompt an election. However, opposition leader Stéphane Dion has expressed an unwillingness to defeat the government on this matter.
