Good morning, viewers. You’re watching ATV News with me, Mufidah Yumna. The first news is New species of dinosaur with ‘unusually large’ nose discovered. A new species of dinosaur with an unusually large nose has been identified by a retired general practitioner in the UK who spent lockdown rummaging through boxes of hundreds of old bones. Jeremy Lockwood, who is studying for a PhD at the University of Portsmouth, set himself the task of cataloguing every iguanodon bone discovered on the Isle of Wight. As the 64 year old from Chale, near Ventnor, Isle of Wight, sorted the bones from the collections of the Natural History Museum in London and the Dinosaur Isle Museum, he discovered the unique “bulbous” nasal bone. Jeremy Lockwood, who is studying for a PhD at the University of Portsmouth, set himself the task of cataloguing every iguanodon bone discovered on the Isle of Wight. As the 64 year old from Chale, near Ventnor, Isle of Wight, sorted the bones from the collections of the Natural History Museum in London and the Dinosaur Isle Museum, he discovered the unique “bulbous” nasal bone. Dr Lockwood, who studies in the school of environment, geography and geoscience, said: “For over 100 years, we’d only seen two types of dinosaur on the Isle of Wight – the plant-eating Iguanodon bernissartensis and Mantellisaurus atherfieldensis. “I was convinced that subtle differences between bones would reveal a new species, so I set out to measure, photograph and study the anatomy of each bone. “My background is medicine, so I’ve studied anatomy and was always struck by the fact that the bones we find in humans all look exactly the same. “I’ve seen dinosaur bones that are reportedly from the same species, but I’ve been baffled as to why they would look so different. “Last year during lockdown, after four years of going through boxes and boxes of bones, I decided to reconstruct the skull of a specimen, which had been in storage since 1978, and to my astonishment I noticed the end of its nose was bulbous. “This discovery made it one of the happiest days of lockdown because it was a sign there really was something different about this particular dinosaur from the Isle of Wight.” Dr Lockwood, working with Prof Dave Martill from the University of Portsmouth and Dr Susannah Maidment from the Natural History Museum, has now named the new species Brighstoneus simmondsi, for a study published in the Journal of Systematic Palaeontology. Brighstoneus is named after the village of Brighstone on the Isle of Wight, which is close to the excavation site. The latter part of the name is in honour of Keith Simmonds, an amateur collector, who was involved in finding and excavating the specimen. – PA The second news is Scientists reverse paralysis in mice, seek human trials. SAMUEL I. STUPP, NORTHWESTERN UNIVERSITY, SAYING: "Spinal cord injury has been a major challenge for science for decades.” Scientists at Northwestern University say they may have found a breakthrough treatment for reversing paralysis in humans after successfully administering a new injectable therapy in mice. “The central nervous system, which includes the brain and the spinal cord, which sends messages between your brain and the rest of your body, has very limited capacity to repair after injury. ”In a new study, the team describes an injection of “dancing molecules” to reverse paralysis in mice and repair tissues after severe spinal cord injuries. Just four weeks after the injection, the injured animals regained the ability to walk. Samuel I. Stupp leads the research. "This is probably the most important paper I have ever written. And it describes a piece of science that was truly unknown." The new breakthrough therapeutic is injected as a liquid directly into the spine. It influences the motion of molecules, in effect, making them ‘dance’, so they can more easily engage— read more in this link : https://news.yahoo.com/scientists-reverse-paralysis-mice-seek-183451672.html
