Physicist Masaaki Yamada wins the 2015 James Clerk Maxwell Prize in Plasma Physics

Masaaki Yamada, a Distinguished Laboratory Research Fellow at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL), has won the 2015 James Clerk Maxwell Prize in Plasma Physics. The award from the American Physical Society (APS) Division of Plasma Physics recognized Yamada for "fundamental experimental studies of magnetic reconnection relevant to space, astrophysical and fusion plasmas, and for pioneering contributions to the field of laboratory plasma astrophysics."

Researchers correlate incidences of rheumatoid arthritis and giant cell arteritis with solar cycles

What began as a chat between husband and wife has evolved into an intriguing scientific discovery. The results, published in May in BMJ (formerly British Medical Journal) Open, show a “highly significant” correlation between periodic solar storms and incidences of rheumatoid arthritis (RA) and giant cell arteritis (GCA), two potentially debilitating autoimmune diseases.

COLLOQUIUM: EXTERNAL PROPULSION AND THE FUTURE OF SPACE ACCESS

At Escape Dynamics we are working on the next generation propulsion technologies with the goal of developing electromagnetically-powered engines operating at 10x the efficiency of chemical rockets. In this talk I will describe results of Escape Dynamics’ R&D efforts and outline our vision for the future of aerospace transportation. The primary focus of the talk will be on the technical aspects of external propulsion in which all or a part of the energy required for launch is coming from a ground-based array of microwave antennas configured to beam microwave energy to the vehicle.

COLLOQUIUM: Adaptive Optics Imaging of Extosolar Planets

More than a thousand extrasolar planets are now known, but most have been detected indirectly through Doppler shifts or photometric detection of eclipses. A handful have been directly imaged, using adaptive optics and diffraction control to suppress the light from the bright central star and reveal a planet 10^5 times fainter. 
I will give an overview of directly detected planets and spectroscopic studies, which have revealed H2O, CO, and CH4 in exoplanet atmospheres.

PPPL data may play role in first NASA space probe dedicated to magnetic reconnection

 

At 10:44 p.m. on Thursday, March 12, NASA launched the Magnetospheric Multiscale mission (MMS), a set of four spacecraft that will study the magnetic fields surrounding Earth. Sent into space aboard an Atlas V rocket from Cape Canaveral, the craft mark the first NASA mission dedicated to investigating magnetic reconnection, a mysterious phenomenon that gives rise to the northern lights, solar flares and geomagnetic storms that can disrupt cell phone service, black out power grids and damage orbiting satellites.
