Tuberculosis, caused by the bacteria Mycobacterium tuberculosis, is a leading cause of death worldwide. In 2017 alone, 10 million people across the globe were affected by the disease, and about 1.6 million succumbed to it.

In a recent study, researchers from the Indian Institute of Technology (ISM) Dhanbad have developed a blood glucose sensor to monitor blood sugar using light. It can measure a wide range of values of blood glucose, between 10 to 200 mg/dl, say the researchers. The average blood sugar level in healthy adults when fasting is between 70 to 120 mg/dl.

A new international citizen science platform wants you to capture birdsongs in the dawn. 

Researchers from IIT Delhi have found that variations in temperature affect crop production and worker efficiency—two crucial pillars of India’s economy.

Humans communicate a lot non-verbally, thanks to the ability of our brain to understand tone. Would computers be able to do this? Currently capable of understanding plain text, they are struggling to learn the emotions behind the words, conveyed through tone. But these machines are catching up fast. Digital audio processing tools equip computers to understand various information in sound, including emotions.Prof Preeti Rao of the Indian Institute of Technology Bombay is an expert in sound processing—an approach that helps us do various useful things, one of which is removing unwanted sounds (or noise) from an audio clip. With her team at the Digital Audio Processing Lab, Prof Rao attempts to understand the nature of sound, reveal the information it may hold, and use it for, say, identifying tracks, melodies or the raga of a song.

A ventilator can be a life-saver for patients whose lungs are damaged by the COVID-19 infection. But India, like all countries grappling with this pandemic, is likely to face a large shortage of ventilators. Manufacturers are unable to source key components such as sensors and flow controllers from abroad due to the current disruptions in global supply chains.To address this shortage, a team of engineers at the Indian Institute of Science (IISc) is currently building a prototype of an electro-mechanical ventilator from scratch, using only components found or made in India, based on guidelines issued by the UK Medicines and Healthcare Products Regulatory Agency. It is expected to be ready within the next couple of weeks.

As COVID-19 pandemic marches on in India with over 800 positive cases and 19 deaths at the time of this article, there is an urgent need for deploying out-of-the-box innovations that can help curb this menace.

Understanding patterns in nature has been of interest to researchers. Some of the popular questions have been around why birds flock together, how groups of bees build their honeycombs out of perfect hexagons, how ants navigate finding the shortest path back to the nest, and the likes. Researchers across the world are trying to decipher and explain how and why such specific patterns emerge.

Every year, the 12th of November is observed as National Birdwatching Day, to mark the birth anniversary of India’s legendary ornithologist, Salim Ali. Regardless of where or when you watch birds, an intimate connection with mother Nature follows. On this national birdwatching day, try birding for a change and see what windows it opens up for you when you sit beside your window looking at the world through a binocular.
