Dinosaurs ruled the earth for hundreds of millions of years, then disappeared so completely that to find even a partially complete skeleton of a single multi-ton animal is rare. Meanwhile, the Virginia Museum of Natural History has scores of fossils of Tanytrachelos ahynis, a 12 to 18-inch reptile that also lived millions of years ago, at the same time as the earliest dinosaurs.
Tanytrachelos is a long-necked reptile that was related to the perhaps better-known nine-foot (up to three meter) long Tanystropheus, also known for its very long neck. They belong to the Protosauria, a suborder of aquatic and terrestrial reptiles. As a contribution to efforts to create a family tree for all protosaurs, a Virginia Tech graduate student is taking advantage of the plentiful and nearby collection of Tanytrachelos fossils to study their preservation and population dynamics.
Michelle Casey of Elk River, Minn., a masters degree student in geosciences at Virginia Tech, will present her findings at the Society of Vertebrate Paleontology meeting in Denver Nov. 3-6 and at the Geological Society of America 116th annual meeting Nov. 7-10, also in Denver.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
