Insects like honeybees and ants live in groups that constantly communicate with each other. In fact, communication networks in some insect groups have been successfully compared to artificial technological information transfer networks. Drawing parallels between such highly coordinated processes in living organisms and their artificial counterparts, a team of scientists from IISc, IISER-Kolkatta and BITS-Pilani, seek a better understanding of network communication, to improve the existing information processing networks.

Professors U. Ramamurty and R. Narasimhan at the Indian Institute of Science (IISc) have been looking into this and identified the mechanisms for both ductile and brittle glasses through detailed experiments, complemented with computer simulations and careful autopsy of fractured surfaces.
A system to package and deliver drugs to each cell of your body, depending on its needs, has been developed at IISc. “Nanocapsules” made from a special type of material can now deliver drugs right inside cancer affected cells in the body.
An artificial surface that does not get wet, and retains its water repellant properties even when kept immersed has been developed at IISc. Researchers were able to control the time for which the water repellant property is maintained; they were also able to demonstrate that resistance to water flow past the surface is reduced. This can result in diverse applications like, better printers, and efficient and cheap blood testing.
Prof Pradeep Mujumdar from the Department of Civil Engineering, IISc, has been awarded the prestigious Alexander von Humboldt Medal by the European Geosciences Union. The award is “reserved for scientists who have performed research in developing countries, for the benefit of the people and society, and have achieved exceptional international standing”.
Imagine your car has been idling for 6 months. If at all it starts, would it feel smooth? Last week, ISRO scientists punched in a few lines of code from Bangalore, and millions of kilometers away, Mangalyaan engines roared to life.
A new type of “Field Emission Device”, used routinely in your flat screen displays, has been developed. Using ribbons made of graphene, a form of carbon, researchers at IISc have shown its potential application as a pressure sensor. This new device is not only energy saving, but also highly stable; their fabrication is also easily scalable and easy to manufacture in large quantities.
The topography of the Western Ghats influences the rainfall over the mountain region, finds a recent study. The Western Ghats,a mountain range that runs parallel to the western coast of India, is home to a diverse range of flora and fauna. Though a world heritage site, it also houses a sizeable human population. Rainfall from the summer monsoon plays a huge role for all inhabitants of the Ghats: the flora and fauna, and the people. Accurate prediction of rainfall in this region will be very useful.
A new “nozzle”, a device used in aeroplanes, can reduce the noise levels in our airports and boost the performance 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.
Made of polyethylene and graphene oxide, the membrane can possibly supplement the reverse osmosis (RO) based water purification systems that are in use today. The paper will be published in the international journal Materials Chemistry A.
