A new signaling pathway appears to play a critical role in the development of heart disease, according to researchers at Stanford University School of Medicine. Now that this marker of cardiac dysfunction, known as the APJ-apelin pathway, has been identified, it could lead to better diagnosis of heart problems, perhaps even allowing doctors to intervene in heart disease by blocking or boosting levels of critical proteins.
"The thing that’s clear is that apelin is increased in heart failure," said Euan Ashley, MD, PhD, a clinical fellow in cardiovascular medicine and one of the lead authors of the study, which is being presented at a Nov. 12 poster session at the annual American Heart Association meeting in Orlando.
"The idea of a blood test to help make a diagnosis of heart disease is very appealing," Ashley said. "But my bigger hope is for therapeutic potential, and given what we know about apelin levels changing a lot during heart failure, either blocking or enhancing this system may provide a treatment for heart failure."

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...
