Results of latest survey show tiger numbers in Russia stable
Results of the latest full range survey indicate that tiger numbers in Russia appear to be stable, say the coordinators of a 2005 winter effort to count the animals, led by the New York-based Wildlife Conservation Society. After a massive winter endeavor to determine distribution and abundance of tigers in the Russian Far East, the last stronghold of Siberian tigers, researchers report that approximately 334-417 adult tigers remain in the region, along with 97-112 cubs. While stressing that results are preliminary, the news is welcome relief to tiger conservationists around the world, who have seen spiraling decreases in tiger numbers in other parts of Asia. The announcement also comes just a few months after WCS conservationists learned the Olga, a 14-year-old Siberian tiger had been killed by poachers, after scientists had been continuously monitoring her whereabouts from more than a decade.
To determine numbers of tigers in this remote, densely forested land, researchers sent out nearly one thousand fieldworkers to canvass the entire region where it is believed tigers could occur. Though wary of people, and seldom seen, tigers nonetheless leave evidence of their presence with their massive footprints in the snow. With some workers spending months in the field and covering over 21,000 km (13,000 miles) of transects by foot, ski, snowmobile, and car, over 4,100 tracks were recorded, most representing multiple tracks of a single individual. Researchers map out the location of all these tracks, and then estimate a minimum number of tigers, based on their size and distribution.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
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...
