Hormone affects females, males differently
University of Minnesota researchers have demonstrated for the first time how estrogen affects learning and memory. They found that estrogen can activate particular glutamate receptors within the hippocampus, the brain region responsible for many aspects of learning and memory. Glutamate is the primary excitatory neurotransmitter in the brain, allowing for fast communication between neurons. By examining hippocampal neurons from rats, researchers also observed that estrogen only activated the processes related to learning and memory in the brains of female rats and not males. While it has been well documented that estrogen influences other behaviors beyond reproduction, including learning and memory, the mechanism has remained elusive. The findings of this research are in this weeks Journal of Neuroscience.
"We believe this is an important first step in understanding not just how estrogen affects learning and memory, but also a variety of non-reproductive behaviors," says Paul Mermelstein, Ph.D., assistant professor of neuroscience at the University of Minnesota and lead researcher. "Estrogen activation of glutamate receptors within other brain regions could also potentially account for the well-documented actions of this hormone on female motor control and pain sensation."

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...
