Presentations: American Heart Association Scientific Sessions 2005
Cardiology researchers at Cedars-Sinai Medical Center have found that a single injection of a harmless virus engineered to carry a beneficial, mutant gene enabled animals to manufacture their own supply of the genes protein product that protects against plaque buildup in blood vessels. As a result, the amount of plaque was significantly reduced, as was an immune reaction that can lead to plaque buildup and rupture, which can cause a blocked artery and heart attack or stroke.
The researchers will present their findings from this and other studies at the American Heart Association Scientific Sessions 2005 Nov. 13 through 16 in Dallas. They are pursuing a variety of approaches to interrupt the complex processes leading to plaque formation and rupture, seeking new ways to treat and even prevent atherosclerosis.

MPQ scientists achieve long storage times for photonic quantum bits which break the lower bound for direct teleportation in a global quantum network.
Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor...

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...
