Temporally shaping the electric field of an attosecond pulse

Chemical reactions are determined at their most fundamental level by their respective electronic structure and dynamics. Steered by a stimulus such as light irradiation, electrons rearrange themselves in liquids or solids. ...

Lynxes in danger

For some years now larger wild animals such as lynxes, wolves, and bears have been spreading out across Europe as existing populations grow and animals are resettled. Yet some populations are still endangered. A research ...

How single-cell archaea determine what direction to swim

Dr. Tessa Quax has identified the structure of a central protein used by archaea to determine the direction to swim. Archaea are single-cell life forms without a nucleus. She also studied which molecular mechanisms are involved ...

Emergence of solvated dielectrons observed for the first time

Solvated dielectrons are the subject of many hypotheses among scientists, but have never been directly observed. They are described as a pair of electrons that is dissolved in liquids such as water or liquid ammonia. To make ...

Nano crystals impact stem cell fate during bone formation

Scientists from the University of Freiburg and the University of Basel identified a master regulator for bone regeneration. Prasad Shastri, Professor of Biofunctional Macromolecular Chemistry at the Institute for Macromolecular ...

Refuting the standard model of electroporation

Strong electric fields can be used to create pores in biomembranes. The method is known as electroporation. Inducing such defects in membranes in a targeted manner is an important technique in medicine and biotechnology, ...

Lipids support protein machinery

In the membranes of mitochondria, the power stations of the cell, are many different embedded proteins. These proteins perform key functions for the mitochondria. A team led by the biochemist Dr. Thomas Becker from the University ...
