Patient patience and pandemics: How to keep patient choice up, stress down in a pandemic Posted: 07 Jul 2014 12:25 PM PDT Allowing patients to choose which hospital they attend when suffering illness during a pandemic rather than assigning them to a specific healthcare facility could be inefficient, according to research. But incentives might redress the balance. A new proposal is based on two assignment models. The first, a decentralized, equilibrium model, describes the patient choice of hospital. The second, centralized, non-linear programming model allows the health authority to maximize resource utilization of all the hospitals in a given region.

Building much smaller, greener electronics: Atom-scale, ultra-low-power computing devices to replace transistor circuits Posted: 07 Jul 2014 12:25 PM PDT The digital age has resulted in a succession of smaller, cleaner and less power-hungry technologies since the days the personal computer fit atop a desk, replacing mainframe models that once filled entire rooms. Desktop PCs have since given way to smaller and smaller laptops, smartphones and devices that most of us carry around in our pockets. Scientists are now developing atom-scale, ultra-low-power computing devices to replace transistor circuits.

Mathematical model illustrates our online 'copycat' behavior Posted: 07 Jul 2014 12:24 PM PDT Researchers examined how users are influenced in the choice of apps that they install on their Facebook pages by creating a mathematical model to capture the dynamics at play.

Satellites reveal possible catastrophic flooding months in advance Posted: 07 Jul 2014 11:17 AM PDT Data from NASA satellites can greatly improve predictions of how likely a river basin is to overflow months before it does, according to new findings. The use of such data, which capture a much fuller picture of how water is accumulating, could result in earlier flood warnings, potentially saving lives and property.

University students developing robotic gardening technology Posted: 07 Jul 2014 08:35 AM PDT For more than a half-century, NASA has made the stuff of science fiction into reality. Researchers are continuing that tradition by designing robots to work in a deep-space habitat, tending gardens and growing food for astronaut explorers. It sounds like a concept from Star Wars, but a team of graduate students from the University of Colorado Boulder is now developing the innovative technology to make it possible.
