The National Biotechnology Development strategy is exciting indeed. The ambition is to turn Indian biotechnology into a 100 billion US dollars industry by 2025. However, how much money DBT/MST is going to invest is not mentioned. Is it really possible to achieve this ambition - within just another 9 years?.Full Text

Influence of the solar cycle on temperature structure is examined using radio occultation measurements by COSMIC/FORMASAT-3 satellite. Observations from January 2007 to December 2015 comprising 3,764,728 occultations, which are uniformly spread over land and sea, have been used to study temperature changes mainly in the troposphere along with the solar cycle over 60°N–60°S geographic latitudes. It was a challenging task to identify the height at which the solar cycle signal could be observed in temperature perturbations as different atmospheric processes contribute towards temperature variability. Using a high spatial resolution dataset from COSMIC we are able to detect solar cycle signal in the zonal mean temperature profiles near surface at 2 km and upward. A consistent rise in the interannual variation of temperature was observed along with the solar cycle. The change in the temperature structure showed a latitudinal variation from southern to northern hemisphere over the period 2007–2015 with a significant positive influence of sunspot numbers in the solar cycle. It can be concluded that the solar cycle induces changes in temperature by as much as 1.5°C. However, solar cycle signal in the stratospheric region could not be identified as the region is dominated by large-scale dynamical motions like quasi-biennial oscillation which suppress the influence of solar signal on temperature perturbations due to its quasi-periodic nature.Keywords

The present study describes a novel approach to distinguish between bio- and fluorescing non-bioparticles from a stand-off distance of 5 m using laser-induced fluorescence technique. The variations of peak fluorescence intensities of bio- and non-bioaerosols with time were observed experimentally. Substantial decay of fluorescence peak intensities with time was observed in case of bioparticles, while it was negligible in case of non-bioparticles. This difference in decay of fluorescence peaks with time can form the basis for making a distinction between bio- and fluorescing non-bioparticles from stand-off distance. Further, this approach can be converted to a handy product for defence and security applications.Keywords
