Mayo Clinic researchers have found that rheumatoid arthritis patients have twice the risk of heart failure, or a weakening of the heart’s ability to pump blood, as those without rheumatoid arthritis, according to a new study to be published in the February edition of the journal Arthritis & Rheumatism. About one-third of the rheumatoid arthritis patients studied developed heart failure over 30 years of the disease.
"We decided to undertake this study because we knew that patients with rheumatoid arthritis die earlier than the general population, and mostly from heart disease," says Paulo Nicola, M.D., Mayo Clinic research fellow in the Department of Health Sciences Research and study author. "We thought heart failure could be a reason for early mortality in these patients. However, we were not expecting that the incidence of heart failure would be so high."
The study found that patients with rheumatoid arthritis are at an increased risk for heart failure soon after the onset of arthritis and that this elevated risk follows them throughout the course of the arthritis, a chronic disease. The researchers also found that the factors putting them at this increased risk for heart failure seem to be unrelated to heart attacks and to the traditional cardiovascular risk factors: diabetes; alcohol abuse; and elevated cholesterol, blood pressure and body mass index. The source of the increased risk remains a mystery, however.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
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...
