Prey have evolved a suite of tricks to avoid falling victim to a predator. They may escape, hide, protect, become toxic/inedible or defend themselves. In principle, they could also scare the predator away, but this is risky when predators are big.
Recent work led by a Dutch research team and published in the July issue of Ecology Letters revealed that a plant-feeding thrips insect overcomes this differential size problem by killing the eggs of its enemy, a plant-inhabiting predatory mite. This infanticide poses a severe threat to these predators, which react by avoiding to lay their eggs and to forage for food at sites where their eggs are killed. Indeed, predation on thrips larvae near damaged predator eggs was almost 4 times lower than on other larvae. Hence, by killing eggs, vulnerable thrips larvae deter dangerous predators and thus reduce their own risk of being food for other insects. This mechanism makes one wonder who`s the predator and who`s the prey.

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.
