Excavation of what is believed to be remains of the first-dated mammoth discovered on the Texas Gulf Coast is in its initial phases but living up to the expectations of its researchers, a team of students and archaeologists from Texas A&M Universitys Center for the Study of the First Americans.
The mammoth was found buried in a sand pit just outside Lake Jackson, Texas in the town of Clute by a backhoe operator for Vernor Material & Equipment Co. who uncovered a pair of tusks. Further examination revealed skull remains and miscellaneous bones.
The mammoth, which could be about 38,000 years old, judging from the age of logs recovered near the site, is believed to be a Columbian mammoth. These mammoths were slightly larger and less hairy than their famous cousin, the wooly. In addition, fossil logs and remains of bison, horse, deer and turtle are present, providing a glimpse of a unique Ice Age environment buried 35 below the surface, said Robson Bonnichsen, director of the Center for the Study of the First Americans

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.

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.

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...
