Weekly Digest 22nd September

This week we bring some more stories and a scientist's profile. 

1) Reducing aircraft noise and improving airconditioning

A new “nozzle”, a device used in aeroplanes, can reduce the noise levels in our airports and boost the performace of aeroplane engines. Developed at the Indian Institute of Science, these nozzles also have potential applications in next generation eco-friendly refrigerators and fuel cells. 

The article is to appear on 5th October 2014 in the journal of Applied Thermal Engineering

5) Scientist profile: Prof. M. Vijayan. "Making the impossible possible"
Prof. Vijayan has been examining the structure of molecules that are found in living systems all his life. After playing a role in deciphering the structure of insulin at Nobel Laureate Dorothy Hodgkin’s lab at Oxford, Prof. Vijayan was “the first trained protein crystallographer to return to India, to the IISc”.
