A joint research team from the University of Calgary, American Museum of Natural History, and Florida State University announced on Monday that the eggs of non-avian dinosaurs such as the duck-billed dinosaur took as long as six months to hatch, far longer than had previously been believed.

Bird eggs incubate for 11 to 85 days, about half the time of most other egg-laying vertebrates. Scientists had thought dinosaur eggs were more like those of modern birds than modern reptiles, but this long hatch time is far more reminiscent of monitor lizard than magpie.

The scientists reached this conclusion by comparing CT scans of the teeth of dinosaur embryos of two different species, the Protoceratops andrewsi, which had eggs weighing under 200 grams, and Hypacrosaurus stebingeri, a type of duck-billed dinosaur that had eggs twenty times that size. They observed the von Ebner lines, patterns that form in vertebrate teeth as they grow, to determine how long the overall developmental process was taking. “They’re kind of like tree rings, but they’re put down daily,” said Florida State University co-author Gregory Erickson. “And so we could literally count them to see how long each dinosaur had been developing.” They found the Protoceratops embryo was about three months old and the Hypacrosaurus about six months.

According to the research team, this may be one reason why dinosaurs did not recover after the Cretaceous-Paleogene extinction event 65 million years ago. Both the eggs and any parents guarding them would have drawn the attention of predators and been unable to flee floods or other problems. Guardians might not have been able to move far to find food. This, researchers say, would have put dinosaurs at a disadvantage over animals with quicker-hatching eggs and their mammalian competitors.

Natural History Museum Curator and study co-author Mark Norell cites advances in imaging technology as the reason why this study is being published today: “We know very little about dinosaur embryology, yet it relates to so many aspects of development, life history, and evolution, [b]ut with the help of advanced tools like CT scanners and high-resolution microscopy, we’re making discoveries that we couldn’t have imagined 20 years ago.”

The research team plans to study more fossilized dinosaur embryo skeletons to confirm their findings. Specifically, the current study did not include the skeleton of a velociraptor or any other dinosaur considered closely related to birds.

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.

YouTube announced that Taiwan Traditional Chinese website has been released yesterday in Taipei City, Taiwan, and the unique web address will be shown as “www.youtube.com.tw” or “tw.youtube.com”. Users from YouTube Global Sites can access Taiwan Site. This site launch will be a benefit for users preferring reading Chinese more than other languages.

In the press conference, co-founder Steve Chen explained the reason choosing “.tw” address, “With lots of good experiences using Traditional Chinese Site in Hong Kong, I think Taiwan should also be. We improved search functions to find more in Taiwan.” He remarked. “YouTube has lots of international sites in many countries including Taiwan, with a keyword, you can find lots of different results in different sites.” YouTube International Manager Sakina Arsiwala said.

Not only the launch by the performance of Eight Generals and Steve Chen, YouTube also invited China Television Co., CommonWealth Magazine, Lion Travel Co., Ltd., and Taiwan Broadcasting System to share experiences of partnership. “We should learn some conceptions on sharing and public service needed in this networking era.” Yuan-hui Hu (President and CEO of Public Television Service, Taiwan) remarked at the Partner Panel of the Press Conference.

After the Press Conference, YouTube held launch and site experience activities at Xinyi Plaza of Shin Kong Mitsukoshi and invited registered users participating in “Beautiful Taiwan” online video competition.

Richard Roberts, the President of Oral Roberts University, and his wife, Lindsay Roberts, are accused of illegal political contributions, financial wrong-doing, and wrongful firings in a lawsuit filed Tuesday.

The lawsuit was filed by three former professors who claim “they were wrongfully dismissed after reporting the school’s involvement in a local political race.” According to KTEN television news, “Roberts’ statement says personal expenses are charged to him and he personally pays them on a monthly basis.” On October 3, Roberts “told students and faculty during his weekly chapel Wednesday that the lawsuit is about intimidation, blackmail and extortion.”

Richard has been president of ORU since his father, Oral Roberts university founder and former faith healer, “semi-retired” in 1993.

The US economy added 173,000 jobs in August, the Bureau of Labor Statistics reported on Friday. The unemployment rate fell from 5.3 to 5.1 percent, the lowest since April 2008.

Although August job gains were lower than most economists forecast, job growth numbers for June and July were revised upwards by a combined 44,000. Average job gains over the past three months stand at 221,000, compared to March-May’s 189,000 monthly average. Over the past twelve months, job growth has averaged 247,000 per month.

Average hourly earnings rose 0.3 percent, or 8 cents, marking the largest increase in earnings in seven months. Hourly earnings had risen by 6 cents in July. Wages have risen by 2.2 percent over the past year.

Job growth in August was primarily concentrated in the health care and social assistance, financial activities, and professional and business services sectors. Those three areas of the economy added a combined 108,000 jobs. Food service and drinking places employment increased by 26,000 over the month, and other economic sectors saw employment hold steady. Manufacturing, on the other hand, saw employment decline by 17,000 in August. A stronger dollar and worldwide economic weakness make US exports less desirable, leading to a flattening in manufacturing employment so far this year after steadily rising in the early years of the US economic recovery.

The solid overall job gains led analysts to slightly raise expectations for a decision by the Federal Reserve to raise interest rates this month. Investors raised the likelihood of a September rate increase from 26 percent before the jobs report to 30 percent, and stocks dropped by over one percent on Friday. “The payrolls data is certainly good enough to allow for a Fed rate hike in September,” said Deutsche Bank’s head of currency strategy, Alan Ruskin. “The big question is still whether financial market volatility will scupper the plans.”

“This is the first time the market has looked at a Fed meeting and really has no idea what the Fed is going to do,” said Mark Kepner, a New Jersey equity trader with Themis Trading. “Right now you’re looking at the overall uncertainty and that’s what’s hanging on the market. I don’t think this number in and of itself changes how somebody’s going to vote.”

The Benet Academy Redwings boys basketball team defeated the Oswego High School Panthers 40–34 Saturday night at Benet’s historic Alumni Gym. 

Located at Lisle, Illinois, United States, the gymnasium is home to Benet’s winning streak of 102 consecutive home games. The statewide record lasted from November 26, 1975 until January 24, 1987, when Naperville North High School defeated the Redwings 47–46. Benet also achieved 96 consecutive victories in the Western Suburban Catholic Conference at that time. 

The school continued to use the facility, colloquially referred to as the “Old Gym” or the “Small Gym”, until the end of the 1994 season, when a newer athletic center was built on campus. It wasn’t until the late 1990’s when then-coach Marty Gaughan decided to play one game per year in the Alumni Gym to remind the school of its history. “There is just an electricity, and you feel it when you are in there,” said Gaughan, who coached the team from the 1989–1990 season to the 2007–2008 season. 

This tradition continued until the 2006–2007 season, when the Redwings played against long-time rival St. Francis High School. Renovations prevented the gym from being used for athletic events over the past two seasons. This game was Benet coach Gene Heidkamp’s first opportunity to coach in the older gym. “So much history and winning has taken place there, which makes it so special. It is something the entire school community is excited about,” said Heidkamp. 

Saturday’s game was played at the Alumni Gym at the request of Oswego assistant coach Jim Bagley. He wanted his son, senior forward Chris Bagley, to experience the same atmosphere he had as he played for Benet in the 1978–1979 season. Greg Kwiatkowski was also Jim Bagley’s teammate in Benet, and his son, Joe Kwiatkowski, was in the Panthers’ starting lineup as well. “Two of us who played at Benet together and now our son’s play on [Oswego] together and for them to have a chance to play where we played is going to be a great night and great experience,” said the senior Bagley. 

Alumni Gym apparently still had its charm in the second half for the Redwings, whose 15–17 score at halftime worsened into an 11-point deficit in the third quarter. Benet fell behind with a score of 21–29 at the start of the fourth quarter. From that point, the Redwings’ defense began to kick in. Oswego could make only 2 of its 13 field goals in the third quarter. Benet’s offense also gained momentum as center Frank Kaminsky scored all of his 9 points in the fourth quarter. A shot by senior Mike Runger brought the score to 31–31, and two consecutive driving layups by David Sobolewski gave Benet the lead that would last for the rest of the game. 

“We hit a dry spell there, but let’s give credit where credit is due. Defense wins games and they are the best defensive team we’ve faced all year,” said Oswego coach Kevin Schnable.

Benet’s Matt Parisi led his team with 15 points, and Sobolewski scored 12. Oswego’s Andrew Ziemnik also scored 12.
