Argentinosaurus (Argentine lizard) was a kind of dinosaur that lived in Argentina, South America in the Cretaceous period around 95 million years ago. It is one of the largest vertebrates (animal having a backbone) to ever walk on the earth, its total estimated length was nearly 40 meters (131 feet) from tip to tail. The estimation length of the dinosaur was taken on the basis of its limited number of bones. It is also under skeptical about its length and about its movement with the help of incredible pressure on the joints. Researchers made a model of the Agrentinosaurus show that it is possible for the large animal to walk using the combined computing power of 30,000 desktop computers. Incomplete skeleton or bones of Argentinosaurus were found.
Its size can be estimated from six lumbar vertebrae, five partial vertebrae from the lumbar region, and a portion of a femur alone. Paleontologists (Scientists concerned with fossil, animals, and plants) were able to estimate the size of the entire animal by comparing these samples to other sauropods. The study, performed by scientists at the University of Manchester, was published in PLOS ONE (Public Library of Science) on October 30. A 40-meter-long duplicate skeleton of the Argentinosaur was scanned for computer modeling. Using bony landmarks to estimate muscle attachments, the computer model estimated the muscle mass that the huge dinosaurs must have had. From its mass, the researchers were able to estimate speed and probable movement. At over 80 tonnes. It probably reached speeds of 2 m/s (5mph). Because all animal having backbones have the same basic muscles and joints, the researchers were able to build off of what can presently be seen in animals and apply it to long-extinct species. However, the team was careful to base their conclusions on what the data actually presented, without adding any preconceived notions of how or if the giant dinosaur would move.
Wolverine, the fictional superhero appearing in American comic books published by Marvel Comics, most commonly in association with the X-Men whereas the X-Men are a fictional team of superheroes. Wolverine has claws made of the unbreakable adamantium which can be extended and claws are sharp as the razor and are fused to his skeleton. It had been a scientific mystery… until now that the cellular processes and managerial channel that allow Wolverine to revitalize so easily. The graduate students from the University of British Colombia, co-authored by mutants Cyclops and Professor Charles Xavier submitted a six-page-long satirical paper to the Journal of Superhero Mutational Science. The paper outlines the genetics of regeneration and attributes Wolverine’s abilities to the protein Howlett (taken from Wolverine’s birth name, James Howlett). Howlett bears many similarities to Amblox, the protein responsible for limb regeneration in axolotls. The paper was also published in The Science Creative Quarterly; an online journal from UBC that celebrates the oddities of scientific research.
The paper published discussion regarding the protein Howlett and protein Amblox which are found in humans and in axolotls respectively. In both mutant humans and or amphibians knocking out the gene that codes for the regenerative proteins resulted in an increased ability for the individual to heal itself. In the field of regenerative medicine for humans, both mutant and wild-type these studies may help in the development of new therapies.
Dr. Conrad Hoskin from James Cook University and National Geographic photographer/Harvard University researcher Dr. Tim Laman went on an expedition earlier this year to research a remote mountain range on Cape York Peninsula in north-east Australia. Though surveys had been conducted in the boulder-fields around the base of Cape Melville, the plateau of rainforest on top had been largely unexplored. A leaf-tail gecko, a golden-colored skin, and a boulder-dwelling frog were newly discovered species by them and were new to science. The above-mentioned species and the other rainforest-associated inhabitants have been completely isolated for millions of years. As they were so isolated, they evolved into distinct species in the unique environment.
The above mentioned newly discovered species have been given the name and published all descriptions in a journal namely “Zootaxa”. The leaf-tailed gecko was a special for the authors whose length was around 20 cm long and it was Gondawanan antique in Australia from a time millions of years ago when rainforest was more widespread. The leaf-tailed gecko has been named as Saltuarius eximius, the meaning of it in English is ‘exceptional’, ‘extraordinary’ or ‘exquisite’. The gecko hides under the rock during the day and comes out at night time to search for its prey on rocks and trees. The gecko is highly camouflaged and sit steady with their head down while waiting to ambush its prey like insects and spiders. The gecko has Huge eyes, a very long and slender body as well as limbs.
Saproscincus Saltus (Skink) was also discovered along with the Cape Melville Leaf-Tailed Gecko. It has long-limbed and golden colored body. It is unlike the gecko because it is active during the day. It runs and jumps while hunting prey, therefore, its name has been given Saproscincus saltus where the meaning of saltus is ‘leaping’. The species is quite different from the other species found in the southern rainforests and this species is entirely limited to the rock-fields of Cape Melville, and these are called ‘rock-loving’. This types of frog live in the Boulder-area during the dry season and in summer the frog comes out onto the surface rocks to feed and to breed in the rain. Eggs of the frog are laid within cracks in the moist rocks and while the tadpoles are developing within and the male frog looks after the eggs laid within until froglets hatch out.
