Bone marrow stromal cells release a blood vessel-dilating hormone found in the brain -- a finding that suggests the hormone may be tapped to help with recovery from stroke or other neurological injuries disrupting blood flow to the central nervous system, researchers at the University of South Florida and James A. Haley Veterans Hospital report for the first time. The hormone is known as brain natriuretic peptide.
The laboratory study was published in the January 2004 issue of the journal Experimental Neurology.
"Were suggesting that transplanted bone marrow stromal cells may hasten recovery by releasing brain natriuretic peptide and other factors that improve blood flow to the brain and decrease swelling and pressure around the site of injury," said lead investigator Juan Sanchez-Ramos, MD, PhD, professor of neurology and research director at the USF Center for Aging and Brain Repair. "By helping irrigate, or restore the blood circulation to the brain, brain natriuretic factor may reduce the extent of damage from stroke or spinal cord injuries."

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...
