Adding greenery in the form of a garden to the often sterile, cold environment of hospitals and other healthcare facilities can reduce stress in patients, visitors and staff and even lessen a patients pain in some instances, says a Texas A&M University authority on health care design.
Roger Ulrich, professor and director of the Center for Health Systems & Design at Texas A&Ms College of Architecture, says a growing body of research is giving credibility to the widely held belief that nature can improve health.
"Knowledge and research into fields such as health psychology and behavioral medicine have demonstrated that there need not be anything magical about the processes through which gardens in healthcare facilities should be capable of reducing stress and improving patients health," Ulrich says.

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...
