A Cure for the Common Cold [SciScoop Science Blog]


Scientists have taken the first-ever look at how the entire human body reacts on the genomic level to the most common disease in the world - the common cold.

Solar pumped laser reaches 80W [Yan Feng -]

A new report from Prof. Takashi Yabe: 100 W-class solar pumped laser for sustainable magnesium-hydrogen energy cycle, J. Appl. Phys. 104, 083104 (2008). They used a Fresnel lens (2×2 m, f=2000 mm) for collecting solar radiation, a Cr:Nd: YAG ceramic rod as gain medium, and get 80 W maximum laser power, corresponding to a 4.3% net conversion from solar light. That's really a cool result.

I always say to my colleagues that solar pumped laser is my dream research project, because then I can do experiments under sunshine instead of in a basement lab. ;)

Dr. Rüdiger Paschotta's books [Yan Feng -]

Dr. RĂ¼diger Paschotta, who runs a consulting company after a successful academic career, just published another book: SPIE Field Guide to Laser Pulse Generation. His first book is SPIE Field Guide to Lasers.

Encyclopedia of Laser Physics and Technology, his notable and useful web project, also has a print version now.

He leads a very interesting career.
