The Internet has revolutionised our way of life, enabling things that were hard to imagine earlier. With the Internet, one can work sitting at home, doctors can treat patients anywhere in the world, and with the advent of smartphones, simple activities like commuting has a whole new meaning. Social media platforms like Facebook, Twitter and YouTube have redefined communication and made reaching out to a large number of people very easy. Any of us can be an ‘influencer’ with the potential to be heard by millions of people.

Technology has revolutionised medicine in the past century. We now have imaging methodologies like X-rays, Computed Tomography (CT) scans and Magnetic Resonance Imaging (MRI) allowing us a look inside the body without cutting it open. Nanotechnology seems poised to write the next chapter of this revolution, with various applications in biomedical imaging, diagnosis and effective treatment of diseases. In yet another advancement in this direction, an interdisciplinary team of scientists from Materials Engineering Department and Department of Microbiology and Cell Biology at the Indian Institute of Science (IISc), Bangalore, have synthesised iron nanoparticles without any oxide cover that could be used to enhance the sensitivity of MRI by producing images with better contrast. They have also demonstrated the potential application of this research in the targeted delivery of medicines and other biological molecules to specific organs in the body.

This year’s National Science Day, celebrated to commemorate the discovery of Dr. C V Raman’s ‘Raman Effect’, is themed around ‘Science and Technology for Specially Abled Persons’. One billion people, or 15% of the world’s population, experience some form of disability today, and the prevalence of disability is highest in developing countries like India. A report by World Bank estimates that about 110-190 million of them experience significant disabilities.  ‘Persons with disabilities’ or PwDs include those who have long-term physical, mental, intellectual or sensory impairments which may hinder their full and effective participation in the society.

Detecting leakage of hydrgoen gas has been a major challenge in using hydrogen as fuel for many applications. This is now made easier by a new study by researchers at the Indian Institute of Technology, Roorkee. They have used  nanotechnology based silicon carbide ‘cauliflowers’ to develop a simple, robust, and cost-effective sensor that can detect hydrogen gas at high temperatures and small quantities. This research is a small step that can make using clean and green hydrogen gas as fuel, replacing conventional fossil fuels.

Now, your laptop too can judge your dance performance and be your ‘Intelligent’ dance teacher

A new research has elevated self-learning to a whole new level by developing an intelligent “judge” who can predict the expertise of a Bharatnatyam dancer. Prof. Dinesh Babu Jayagopi and his team at the International Institute of Information Technology, Bangalore, have designed Machine Learning based software that predicts a dancer’s expertise by observing his/her poses and expressions during a dance performance. Such a software can also be used to automatically tag videos and analyse its contents in a video database like YouTube, thus simplifying video search.

Internet of Things

The ‘Internet of Things’ (IoT) is the new buzzword in technological corridors with most technology companies announcing a ‘smart’ device of sorts that runs on IoT. In simple terms, IoT is a giant network of connected ‘things’; a network of devices linked to Internet through wired or wireless connections. ‘Things’ could be anything from everyday devices like cell phones, washing machines and wearable devices, to pacemakers, biochips on farm animals, automobiles and industrial machines. It is estimated that, by 2050, a whopping 50 billion such ‘connected’ devices would emerge, dawning a new era of the Internet - one of the most powerful inventions in human history.
