Uric acid is a compound made of carbon, nitrogen and oxygen, and is one of the components in urine. High amounts of uric acid in the blood could lead to many debilitating medical conditions such as diabetes and gout. However, detecting the compound in living cells without damaging the cells can be quite a challenge. Now, scientists from Visva- Bharati Santiniketan, West Bengal, Indian Institute of Engineering, Science and Technology, Howrah and University of Calcutta, Kolkata have devised a novel way of detecting uric acid without disrupting the cell.

India is no stranger to air pollution, with the capital, New Delhi, being identified as one of the most polluted cities in the world, several times. The harmful effects of this deteriorating air quality can be seen in the increasing number of patients with respiratory disorders. Now, a team of scientists have designed a novel gas sensor using MEMS technology that is compact, highly sensitive, consumes very little power and accurately detects gaseous pollutants like CO, CO2, NO2 & SO2.

How do we test the strength and rigidity of the materials used by engineers to build? We could use a sample of the material that we wish to study, and bombard it with projectiles to study how the material reacts to the bombardment. This method, however does not allow us to understand the behaviour of the test material at a microscopic level.

The Bellatrix Aeroscape team presented the award by President of India, Shri Pranab Mukherjee.

The race to space is heating up with the addition of private players around the world. With increasing competition to make space explorations affordable, there is a whole ecosystem of small and big companies trying to eye the possible revenues. One among them is the award winning start-up from Bangalore, incubated at IISc, called Bellatrix Aerospace. In a recent conversation with Research Matters, the company reveals its plans for the future and talks about its innovative solutions that aim to make space explorations cheaper than ever.

Lignin, like cellulose, is an insoluble fibre found in many fruits and vegetables including kiwi, ridge gourd, carrots, spinach and kale. In a recent study, scientists from the Vivekananda College of Pharmacy, Indian Institute of Science (IISc) and Poornaprajna Institute of Scientific Research (PPISR) have prepared lignin-rich nanoparticles from vegetables by treating their fibres with special enzymes thus making it ‘green’.

IISc ERNET team circa 1990

The Education and Research Network or better known as the ERNET project was initiated in 1986 by the central government with the aim of connecting the different academic institutions across the country and introducing research in networking in the country. By 1992, ERNET had become the country’s first internet service provider. In January 2016 it was mutually decided to end the agreement between ERNET and IISc, thus bringing to an end a three-decade long effort in data networking.

Have you ever wondered what billions of years of evolution has left us with? Incredible answers to some of the toughest questions, say scientists. In fact, it has given rise to a new field called biomimicry that aims to provide some of the incredible solutions to design problems inspired by nature. Think of the aeroplanes, super fast bullet trains, artificial glues for bones, climate controlled buildings -- all these are a result of us looking close into nature’s way of dealing with problems and drawing an inspiration from them. But there are more such examples that are gamechangers. Read more to know how biomimicry is all set to influence our lives more than ever.

Malaria, a deadly mosquito borne disease, kills about half a million people around the world, every year. Developing countries face a challenge in accurately diagnosing malaria in early stages due to the need of sophisticated diagnostic devices and skill. A new study at IISc has developed a technique to test for malaria with very small quantities of blood samples using laser light. By holding a single RBC using a pair of 'optical tweezers', this technique can detect malarial parasites in the RBCs even at an early stage, say the researchers. The researchers claim this technique can help save many lives if commercialised on a larger scale.

Securing communication channels has been a long standing challenge for humans ever since early civilisations. Thanks to advances in computation, many so called 'secure' algorithms have been broken and the risk of information being in the wrong hands is at an all time high. A new study by researchers from IISc and NIT-Karnantaka has now developed an improvised version of a cryptographic algorithm based on quantum physics. This algorithm, the researchers claim, works efficiently and faster than their previous versions and allows higher data rate. They also also developing a new breed of communication devices running the improvised algorithms. These devices, the researchers claim, can be integrated into existing infrastructure, making them all the more secure.

Nature has inspired humanity in many ways. A whole new field of biomimicry has now evolved, which deals with nature inspired techniques to address many of our challenges. Now, a new study inspired by the eye structure of trilobites -- sea creatures known to be extinct since the age of dinosaurs -- has discovered a novel method of lens fabrication that can ward off spherical aberration. The scientists have fabricated these lenses based on the shape of trilobites’ eyes which are unique and are not adjustable. These lenses, the scientists say, have superior optical performance and find use in a range of optical applications.
