Higher hospital readmission rates for cardiac patients in Northern vs. Southern Ontario: Importance

Patients hospitalized with heart attacks, heart failure, atrial fibrillation or stroke in Northern Ontario, Canada, were more likely to be readmitted to the hospital and repeatedly hospitalized after discharge than those living in Southern Ontario. Yet, no geographical differences were found in 30-day survival. A new study recommends providing access to timely transitional care by clinicians who have the knowledge and expertise to treat patients recently discharged from hospital as one of several strategies necessary to reduce hospital readmission rates.

Layering titanium oxide's different mineral forms for better solar cells

A research team has improved the efficiency of a new type of solar cell with a double layer consisting of pure anatase and brookite, two different mineral forms of titanium oxide. Using water-solute brookite nanoparticles, a brookite layer was fabricated on top of anatase, increasing solar cell efficiency by up to 16.82 percent.

Interactive surfaces enter a whole new dimension of flexibility

Researchers propose a novel flexible tube display that is able to take various surface shapes. Information is expressed by streaming colored fluids through the tube and controlling the positions and lengths of the droplets. The tube's flexibility makes it possible to wrap the tube around the surface of an object and present information on its surface that is difficult to express on a standard two-dimensional display.
