Light it up: Reimagining the optical diode effect

Sciencedaily.com 

A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by passing light at shortwave infrared wavelengths used in optical communications. Furthermore, they have uncovered that it is possible to switch the optical diode effect by applying a magnetic field. This is a step forward in the development of an innovative optical isolator that is more compact and can control light propagation... Читать дальше...

Moon rocks with unique dust found

Sciencedaily.com 

A research team has for the first time discovered anomalous meter-sized rocks on the lunar surface that are covered in dust and presumably exhibit unique properties -- such as magnetic anomalies. These findings help to understand the processes that form and change the lunar crust.



Chemical synthesis: New strategy for skeletal editing on pyridines

Sciencedaily.com 

A team has introduced a strategy for converting carbon-nitrogen atom pairs in a frequently used ring-shaped compound into carbon-carbon atom pairs. The method has potential in the quest for active ingredients for new drugs, for example.

DNA construction led to unexpected discovery of important cell function

Sciencedaily.com 

Researchers have used DNA origami, the art of folding DNA into desired structures, to show how an important cell receptor can be activated in a previously unknown way. The result opens new avenues for understanding how the Notch signalling pathway works and how it is involved in several serious diseases.

New cause of neuron death in Alzheimer's discovered

Sciencedaily.com 

The cause of neuron death in Alzheimer's disease is poorly understood. A new study shows RNA interference may play a key role. Scientists have identified short strands of toxic RNAs that contribute to brain cell death and DNA damage in Alzheimer's and aged brains. Increasing protective short RNAs may be new approach to halt or delay Alzheimer's. The study also found that older individuals with a superior memory capacity (known as SuperAgers) have higher amounts of protective short RNA strands in their brain cells.

New technique visualizes mechanical structure of the cell nucleus

Sciencedaily.com 

The cell nucleus is considered to be the control center of vital cellular processes, but its material properties continue to puzzle scientists. An international research team has now developed a new technique that provides a previously unattainable view of the mechanical properties inside this control center. For the first time, it has been possible to visualize over time its peculiar dynamic structural features in living cells, which appear to be crucial for cell function.
