Dr Cucchi was working in Cyprus examining archaeological remains of mice teeth from the Neolithic period and comparing them with those of four known modern day European mice species, to determine if the house mouse was the unwelcome guest of the human colonisation of the island 10,000 years ago.
Dr Cucchi said: “New mammal species are mainly discovered in hot spots of biodiversity like South East Asia and it was generally believed that every species of mammal in Europe had been identified. This is why the discovery of a new species of mouse on Cyprus was so unexpected and exciting. To understand the origin of this new mouse I compared its teeth morphology with the ones of fossils mice collected by palaeontologists. This comparison revealed that this mouse colonised and adapted to the Cypriot environment several thousand years before the arrival of man.”
Mus cypriacus differs to other European mice, it has a bigger head, ears, eyes and teeth. Once genetic tests had confirmed that the new mouse was of a different species it was named Mus cypriacus, genus Mus (Rodentia, Mammalia), only to be found on Cyprus.
This discovery revealed that an endemic species of mouse had survived man’s arrival to the island and now lived side by side with common European house mice, whose ancestors had arrived with man during Neolithic colonisation. This is very unusual because all other endemic mammals of Mediterranean islands died out following the arrival of man with the exception of two species of shrew. The new mouse of Cyprus is the only endemic rodent still alive, and as such can be considered as a ‘living fossil’.
Dr Cucchi continued: “The discovery of this new species and the riddle behind its survival offers a new area of study for scientists studying the evolutionary process of mammals and the ecological consequences of human activities on island biodiversity.”

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
