How postdoctoral researchers are categorized

Postdoctoral

In a forthcoming opinion piece in the journal eLife, eight scientists and science policy experts make the case for standardizing how postdoctoral researchers are categorized by human resources offices and provide a framework that willing institutions can follow. The authors argue that the widespread use of inconsistent titles for researchers …

Some bacteria use a nanosized speargun to get rid of competitors

bacterial speargun

In order to get rid of unpleasant competitors, some bacteria use a sophisticated weapon — a nanosized speargun. Researchers at the University of Basel’s Biozentrum have now gained new insights into the construction, mode of action and recycling of this weapon. As they report in the journal Nature Microbiology, the speargun …

Biological particles are ideal for arrangement of nanoparticles

Nanocomposite

It has always been the Holy Grail of materials science to describe and control the material’s structure-function relationship. Nanoparticles are an attractive class of components to be used in functional materials because they exhibit size-dependent properties, such as superparamagnetism and plasmonic absorption of light. Furthermore, controlling the arrangement of nanoparticles …

Method to decipher the spatial organization of biological structures

Protein structure

Researchers are constantly expanding their arsenal of methods to decipher the spatial organization of biological structures. Using microscopes, they can now visualize individual macromolecular components within DNA, protein, or other complexes. However, this resolution typically requires sophisticated equipment applied to specially-processed samples, and it is difficult to simultaneously watch many …
