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.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
