Suggested causes: pollution of water sources, radiation changes and the effects of a dwindling population
In the Community Ecology Lab, headed by Prof. Leon Blaustein, researchers have found a salamander tadpole which has two heads. Researchers at the lab, Dr Ori Segev and Antonina Plavikov, noted that while they had observed an incidence of deformity, especially among the limbs of salamanders, in the past such cases of two heads were more rare.
The reason for this deformity is unknown, but the chief theories are pollution of water sources, changes in radiation and the influence of a small population.
The Salamander of Israel is an endangered species, mainly due to factors which have disturbed its habitat such as soil and water pollution and the destruction of its natural habitat.
Prof. Blaustein’s lab has been conducting research for many years to try to understand the biological mechanisms of this unique life form, with the aim of helping the nature and parks authorities maintain the existing population and revive populations in danger.
According to researchers at the lab the salamanders act as a signal for the general health of the environment, because they are so sensitive to pollution and environmental changes and so they are the first to be harmed.

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...
