Columbia University Medical Center study shows link between depression and worsening heart disease
Depression is known to be "hard on the heart" – now researchers are a step closer to understanding why. A new Columbia University Medical Center study examining potential links between depression and heart disease found that heart disease patients who showed symptoms of depression were substantially less adherent to taking a prescribed medicine than patients without depression. Patients who continued to show signs of depression three months after a heart attack or angina only took prescribed medications 67 percent of the time, compared to almost 90 percent in non-depressed patients.
The research, which was presented for the first time at the 63rd American Psychosomatic Society Annual Meeting is part of the Coronary Psychosocial Patient Evaluation Study (COPES), a multi-site, multi-project consortium that is funded by the National Heart, Lung, and Blood Institute. According to Karina W. Davidson, Ph.D., assistant professor of medicine at Columbia University Medical Center and principal investigator of the study, it was known that depression in heart disease patients increases the risk of death after a heart attack, but the explanation for the link had remained unclear until now.

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
