IN December 1973, during observations from the space observatory Orion 2 on Soyuz 13, three spectrograms of Capella (α Aur, GO III, mv=0.2) were obtained in the wavelength region 2,000–3,000 Å. The spectrograms were made by a wide-angle meniscus telescope of the Cassesgrain system, with an aperture diameter of 240 mm, an equivalent focal length of 1,000 mm, and a 4-grade quartz prism objective. The dispersion of the spectrograph was 170, 280 and 550 Å mm−1, at wavelengths of 2,000, 2,500 and 3…

Microfluidic single-cell mRNA isolation and analysis.
TLDR
Microfluidics is utilized to isolate picogram and subpicogram mRNA templates, as well as to synthesize cDNA from these templates, which form the foundation for highly parallel single-cell gene expression studies.
