The HealthTech NextGen 2011 Conference, held in San Francisco recently, highlighted this by calling attention to at least 6 disruptive changes that are still ahead in healthcare.
The Health profession knows it’s inevitable that automation will become the status quo. Cerner does a nice job of training healthcare workers to adopt and adapt to emerging technologies. http://www.cerner.com explains the principle benefit of working from a single database rather than the complexities involved in tying multiple databases together with software patches.

The researchers first reported the creation of three-dimensional nanobatteries last December. In that project, they encased vertical arrays of nickel-tin nanowires in PMMA (Plexiglas) that served as an electrolyte and insulator. They grew the nanowires via electrodeposition in an anodized alumina template atop a copper substrate.
In that battery, the encased nickel-tin was the anode, but the cathode had to be attached on the outside.
The new process tucks the cathode inside the nanowires, the researchers said. They used PEO as the gel-like electrolyte that stores lithium ions and also serves as an electrical insulator between nanowires in an array.
After much trial and error, they settled on an easily synthesized polymer known as polyaniline (PANI) as their cathode. Drop-coating the widened alumina pores with PEO coats the insides, encases the anodes and leaves tubes at the top into which PANI cathodes could also be drop-coated. An aluminum current collector placed on top of the array completes the circuit.
The experimental batteries are about 50 microns tall and show good capacity, the researchers said. They are fine-tuning the materials to increase their ability to repeatedly charge and discharge, which now dro…
