Also helps understand role of kidneys in hypertension
In related discoveries with far-reaching implications for treating diabetes and understanding hypertension, University of Utah researchers have learned why thiazolidinediones (TZDs), a major anti-diabetes drug, cause edema and also have found a new pathway critical to fluid metabolism. Identification of this pathway may help understand fundamental mechanisms of blood pressure control.
Using knockout-gene technology, the U of U School of Medicine researchers found that when TZD is activating a nuclear receptor, the peroxisome proliferator-activated receptor gamma, in the collecting duct in the kidney, it serves as a mechanism for fluid retention, or edema. The researchers suggest that the distal nephron, for example the collecting duct, is crucial for regulation of sodium balance and blood pressure. The research is published this week in the Proceedings of the National Academy of Sciences online.

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...
