New device harnesses sun and sewage to produce hydrogen fuel Posted: 10 Oct 2013 05:53 PM PDT A novel device that uses only sunlight and wastewater to produce hydrogen gas could provide a sustainable energy source while improving the efficiency of wastewater treatment. The hybrid device combines a microbial fuel cell (MFC) and a type of solar cell called a photoelectrochemical cell.

Spinning-disk microscope offers window into the center of cell Posted: 09 Oct 2013 06:38 PM PDT A new method of imaging cells is allowing scientists to see tiny structures inside the "control center" of the cell for the first time.

New strategy to treat multiple sclerosis shows promise in mice Posted: 09 Oct 2013 10:22 AM PDT Scientists have identified a set of compounds that may be used to treat multiple sclerosis (MS) in a new way. Unlike existing MS therapies that suppress the immune system, the compounds boost a population of progenitor cells that can repair MS-damaged nerve fibers.

Astronomers stumped by 'flyby anomaly': Unexplained variation in spacecraft speeds Posted: 09 Oct 2013 08:11 AM PDT A mystery that has stumped scientists for decades might be one step closer to solution after European Space Agency tracking stations carefully record signals from NASA's Juno spacecraft as it swings by Earth. Engineers hope that the new measurements will unravel the decades-old 'flyby anomaly' -- an unexplained variation in spacecraft speeds detected during some swingbys.
