Location-tracking apps on smartphones could be used to help track and manage care for thousands of patients who suffer from chronic diseases, and possibly even provide feedback to them on lifestyle changes that could help, according to an initial assessment by researchers at UC San Francisco.

In the study, researchers provided a smartphone app to 3,443 participants age 18 and older from all 50 states. The app, which was developed by app developer Ginger.io in collaboration with study investigators, used “geofencing,” a location-based program that defines geographical boundaries. This app tracked participants when they entered a hospital and triggered a questionnaire when they were located in the hospital for more than four hours.

Important microscopic creatures which produce half of the oxygen in the atmosphere can rapidly adapt to global warming, new research suggests.

Phytoplankton, which also act as an essential food supply for fish, can increase the rate at which they take in carbon dioxide and release oxygen while in warmer water temperatures, a long-running experiment shows.

Monitoring of one species, a green algae, Chlamydomonas reinhardtii, after ten years of them being in waters of a higher temperature shows they quickly adapt so they are still able to photosynthesise more than they respire.

Yale scientists have developed an ultra-thin coating material that has the potential to extend the life and improve the efficiency of lithium-sulfur batteries, one of the most promising areas of energy research today.

In a study published online March 20 in the Proceedings of the National Academy of Sciences, researchers describe the new material — a dendrimer-graphene oxide composite film — which can be applied to any sulfur cathode. A cathode is the positive terminal on a battery.

Mitsubishi Hitachi Power Systems (MHPS) and Carnegie Mellon University (CMU) today announced the creation of a new index that will measure carbon dioxide emissions from the U.S. electrical power generation sector. The Carnegie Mellon Power Sector Carbon Index will track the environmental performance of U.S. power producers and compare current emissions to historical data collected nationwide for more than two decades. A quarterly press release will inform interested parties of power sector carbon emissions performance trends.  In addition, CMU will provide an online resource for a wide variety of power sector emissions data and forecasts.

No one keeps time quite like NASA.

Last month, the space agency's next-generation atomic clock was joined to the spacecraft that will take it into orbit in late 2017.

That instrument, the Deep Space Atomic Clock was developed by NASA's Jet Propulsion Laboratory in Pasadena, California. On Feb. 17, JPL engineers monitored integration of the clock on to the Surrey Orbital Test Bed spacecraft at Surrey Satellite Technology in Englewood, Colorado.
