Research Matters

An international team of scientists from China, the USA, the UK, Hungary, Austria, Germany and India, have carried out observations of the Sun using the Goode Solar Telescope (GST) at the Big Bear Solar Observatory in the USA. Their study is published in the journal Science.

Dr Siddhesh Kamat, Assistant Professor at the Indian Institute of Science Education and Research (IISER) Pune, is among the 27 recipients of the European Molecular Biology Organization's (EMBO) Young Investigators Grant. EMBO is an organization headquartered in Heidelberg, Germany, and promotes international collaboration among life sciences researchers.

We all know that the geometric object of minimal surface area amongst all shapes with a fixed volume is the round ball, whose boundary is spherical. Water blobs try to minimise surface area and curl into spherical droplets. The physical problem of surface-area minimisation is thus quite well understood. What about the opposite problem of surface-area maximisation? Does the problem even make sense? Indeed it does. Trees try to maximise surface area to get the most of sunlight through their leaves.

In 2018, around 1.5 million people died from tuberculosis (TB) — an infectious disease that mainly affects the lungs. A major obstacle in the clinical treatment of TB is the long therapy time required to clear the infection. An infected patient needs to take antibiotics for over 6 to 9 months to prevent a relapse — a duration so long that many discontinue their medications.

From the 5th of November 2019 to the 8th, India saw one of its extravagant science events, the India International Science Festival, organised in Kolkata. The event was organised by the Ministry of Science & Technology and Earth Sciences, Government of India, in association with Vijnana Bharati (VIBHA) and hosted many conferences, conclaves and exhibitions aimed at anyone enthusiastic about science. Although this was the fifth edition of the science festival, it was the first time a dedicated Science and Technology Media Conclave was held as a part of IISF—a move that had many science communicators, writers and journalists enthused. It was spread over two days, the 6th and 7th of November, at the legendary Bose Institute.

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.

In a recent study, researchers from the Indian Institute of Technology Kanpur have explored the use of a new blend of chromium (III) as an eco-friendly electrolyte for depositing chromium-based coatings on metallic barrels. They reinforced chromium with carbon nanotubes (CNTs) and a ceramic compound called yttria stabilised zirconia (YSZ), to improve the properties of the coat.

In a recent study, Mr Kamath, now a researcher at Gubbi Labs, Bengaluru, along with Dr Seshadri KS, a researcher at The Madras Crocodile Bank Trust and Centre for Herpetology, Tamil Nadu, has reported the feeding behaviour of Brown mongoose. Though accidental, the study adds knowledge about some previously unknown behavioural aspects of these elusive mongooses. It is published in the Journal of Threatened Taxa.

Disgusting, annoying or beneficial? What would you call these pestering fruit flies that don’t miss an opportunity to sit on your favourite cut fruit or visit your kitchen a few times? Whatever you call them, did you know we owe a great deal of our knowledge on evolution to these pesky flies? Ever wondered what’s the lifestyle of Drosophila melanogaster, as they are scientifically called, within the four walls of a laboratory where they are experimented upon? Here is a sneak peek.

Imagine just switching on your lights and downloading a movie in a second. The world demands high-speed internet connectivity at a lower price. This increasing clamour for speed and bandwidth is opening up new avenues, and one such evolving domain is LiFi - a wireless technology that makes use of light-emitting diodes (LEDs) to transmit data. Light waves are 10,000 times denser than WiFi signals, so there is vast untapped potential here.
