Bolivia’s sprawling Kaa-Iya Gran Chaco National Park, known for some of the world’s highest densities of ticks, may now lay claim to another superlative: more jaguars than any protected area on earth. According to a recent study by the New York-based Wildlife Conservation Society (WCS) and other groups, published in the Journal of Zoology, as many as 1,000 of these elusive big cats may call Kaa-Iya home.
Using methodologies developed by WCS to count tigers in India, the researchers employed remote camera "traps" to photograph jaguars, recording each animal’s unique spotting pattern. Through a statistical analysis that counts each animal re-photographed within a given territory, an accurate population estimate can be determined.
"Our results show that the Chaco is rich with jaguars – and Kaa-Iya in fact probably contains the largest population recorded in any protected area," said WCS conservationist, Dr. Andrew Noss, who co-authored the paper along with representatives of Fundación Ivi-Iyambae, Captinía de Alto y Bajo Isoso, a Bolivia-based indigenous group that helps manage the park.

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...
