On-the-fly resolution enhancement in X-ray protein crystallography using electric field.

X-ray crystallography has tremendously served structural biology by routinely providing high-resolution 3D structures of macromolecules. The extent of information encoded in the X-ray crystallography is proportional to which resolution the crystals diffract and the structure can be refined to. Therefore, there is a continuous effort to obtain high-quality crystals, especially for those proteins, which are considered difficult to crystallize into high-quality protein crystals of suitable sizes for X-ray crystallography.

Neuropathology in 1984: a deadly shot into the heart of Europe.

Just 40 years ago, Europe was divided into the Eastern communist bloc, which included the Czechoslovak Socialist Republic (ČSSR) and was dominated by the now historical Soviet Union, and the Western bloc comprising democracies such as Austria. The Iron Curtain, a heavily guarded and deadly border zone, separated the two blocs and constrained, in prison style, the populations of the Eastern bloc. The present neuropathological article relates the sad fate of František Faktor, a 33 years-old Czech who was shot by ČSSR border guards when attempting to flee to Austria at the border between and .

Phylogenomics and a new classification of the tropical genus L. (Monocots, Zingiberales, Heliconiaceae).

Members of the genus L. (Heliconiaceae) have evolved complex interactions with both insect herbivores and hummingbird pollinators in tropical forests and secondary growth where they are abundant and diverse. Many of these same species have also been cultivated as ornamentals around the world for hundreds of years because of their extraordinary colors and forms.

Dating the origin of a viral domestication event in parasitoid wasps attacking Diptera.

Over the course of evolution, hymenopteran parasitoids have developed a close relationship with heritable viruses, sometimes integrating viral genes into their chromosomes. For example, in parasitoids belonging to the genus, 13 viral genes from the family have been domesticated to deliver immunosuppressive factors to host immune cells, thereby protecting parasitoid offspring from the host immune response. The present study aims to comprehensively characterize this domestication event in terms of the viral genes involved, the wasp diversity affected by this event and its chronology.
