New findings explaining the complicated process by which the "energy substations" of human cells split apart and recombine may lay the groundwork for new treatment approaches to a wide range of diseases, including some cancers and neurodegenerative diseases such as Parkinsons and Alzheimers.
Researchers from The Johns Hopkins Universitys Integrated Imaging Center; the University of California, Davis; and the California Institute of Technology collaborated on two new studies analyzing the mechanisms and proteins that underlie the fission-fusion cycle of the cellular powerplants, called mitochondria. Their findings were published in two recent issues of the journal Science.
"To understand the role that mitochondria play in both normal and aberrant cell biology, it is essential to first understand the fusion-fission process that occurs continuously in normal, healthy cells," said J. Michael McCaffery, a research scientist in the Johns Hopkins Department of Biology, director of the Integrated Imaging Center, and an author on both studies.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
