Cloud computing has emerged as the preferred method for processing large amounts of data. It offers the luxury of processing all the data without owning large processors yourself, while the pay-as-you-use model, also allows for economical use of these resources. However, drawbacks such as latency in transferring the data and requirement of bandwidths have given rise to portable cloud computing devices, like Edge and Fog. Now, read about ECHO- a new software platform from IISc that allows you to build and customize applications for Internet of Things and Cyber Physical Systems.

Red blood cells (RBC) are the primary carriers of oxygen in all the vertebrates They pick up oxygen from the lungs, flow through the circulatory system and deliver the oxygen to the different cells and tissues. White blood cells (WBC), on the other hand, are the bodies primary defense system. Produced in the bone marrow, WBC helps the body fight invaders, like virus and bacteria.
Mosquito borne diseases like malaria and dengue are still rampant and have posed a great challenge to mankind. We have lost several lives in our war against mosquitoes, and scramble new ways to fight them. Now, researchers are working to genetically engineer the genes of mosquitoes using the technique of RNA interference, where an RNA is artificially inserted to disturb the normal functions of mosquito cells, thereby killing them in the process. This process, they claim, is environmentally friendly and most effective compared to existing strategies.
The Smart Cities Mission of the Indian government aims to develop at least 100 cities around the country in to smart cities. Internet of Things and Cyber Physical Systems, the two technologies that will enable the smart city dream, still in nascent stages and require enormous efforts from researchers and engineers to set up the framework for such cities. Scientists are now looking to use crowdsourcing as an effective measure to collect the data and effectively implement certain smart applications.
The fossil fuel crisis arising due to our increased use of oil leading to diminishing oil reserves, is giving rise to an increase in renewable energy generation. While solar and wind are preferred to produce electricity, biodiesel is preferred as a replacement to petrol and diesel. Biodiesels are produced from plant or animal matter, like vegetable oil, animal fat or even waste cooking oil. Although biodiesels still produce exhaust gases, they are much cleaner and safer compared to the toxic fumes coming out of fossil fuel powered engines.
The field of material science has immensely contributed to our progress and has arguably been a very important driving force behind all the scientific achievement that mankind boasts of today. With the discovery of conductors, superconductors, insulators and semiconductors, there has been a revolution in the field of electric engineering, computer science, electronics, aerospace and others. Now, a new class of materials to this list is topological conductors, which promises to conquer great frontiers in the field of quantum computers and others. A new research has now shown that amorphous materials like glass can also become topological conductors, thus finding a myriad of applications in different fields.
Rainfall extremes have had devastating effects in the country, including floods in Gujarat and landslides in Darjeeling, both of which claimed many lives. With a warming climate, such extreme rainfall events are only going to increase.
Today, India’s space programs command the world’s respect for a multitude of things -- our Mangalyaan mission was the cheapest ever, we recently launched about 108 satellites into space with a single rocket, our Chandrayaan mission is making fantastic discoveries on the Moon, we launched our own space based observatory with Astrosat...the list goes on. But when the country started its space program, it had very humble beginnings that are hard to believe. It required the courage and determination of many intellectuals and Prof. U R Rao is one of those who scripted a new chapter in India’s history of space research. Here is an orbituary piece dedicated to the life of a great visionary that we just lost amongst us.
Getting stuck in a huge traffic jam is a tragedy, especially if you live in cities like Bengaluru, Mumbai or Delhi. The rising number of vehicles are increasingly adding to this problem, depriving us of our time, money and health. A new research now attempts to reduce traffic pileups in cities by using videos of surveillance cameras. Using Artificial Intelligence and Convolutional Neural Networks, the researcher have built TraCount, a system that can count the number of vehicles in a traffic jam and help authorities manage the congestion in a smart and informed way.
A visit to a doctor for minor ailments may soon be a thing of the past, with rapid rise in medical technologies. Nowadays, a smartphone can help with disease diagnosis and contacting the relevant specialists from around the world, all from the comfort of one’s home. Mobile Healthcare or mHealth has been significantly advanced with the advent of Internet of Things, where sensors can feed live data to specialists, who can monitor patients from miles away. This rapid rise of mHealth has some worried about the security aspects of the software.
