Nanotechonology, the field of science that manipulates objects at atomic or molecular level, is tout to be the science of the future. Researchers across the globe are working rigorously to tapthe potential this possesses. In a recent multinational collaborative study, researchers from the Indian Institute of Science(IISc), Bangalore, the Heriot-Watt University, Edinburgh, UK, and the Georg-August-Universität, Göttingen, Germany, have tried exploring the biomedical applicability of zinc oxide (ZnO) nanostructures. The results of this study have opened up novel possibilities in nanoscience research, especially pertaining to the field of biomedicine.

The traditional Asian chewing package used in marriages for symbolising heavenly love, is no longer having its heavenly charm according to a new research. Areca nut, packed with betel leaves and slaked lime, is an important chewing dessert in many Asian cultures. Its usage to cure indigestion and impotence dates back to first century AD and it is still being consumed by around 700 million people in the tropics for its psychoactive and brain stimulating properties. However, studies have indicated that several chemical compounds present in areca nut are carcinogens and its usage has been linked to oral cancers. Now a new study points at a detailed pathway on how chewing areca nut causes a precancerous condition.

Nano-size polymers have made headlines in the recent years for their biological and medical applications. With dimensions of less than 100 nanometers (nm), they can carry drugs and pharmaceuticals in the body due to their subcellular size, sustained release properties and biocompatibility with our tissues and cells. But how are these nano-size polymers synthesized? In a recently written book chapter in the book, ‘Nano-size polymers: preparation, properties, application’, Prof. Manas Chanda, a retired faculty from the Indian Institute of Science, Bangalore and an expert in the field of polymers, has enunciated the direct synthesis of these tiny polymers by a method called microemulsion polymerization.

In a multinational collaborative study, researchers have designed a novel mobile app that can help novice designers in converting existing artifacts or mechanical objects into abstract representations. Prof. Amaresh Chakrabarti from the Centre for Product Design and Manufacturing, Indian Institute of Science, Bangalore and his team, consisting of researchers from Taiwan, have used Augmented Reality to build this tool that can aid design innovation.

In a collaborative study between the Indian Institute of Science (IISc), Bangalore, and the University of Twente, The Netherlands, researchers have designed a new algorithm for image recovery in Photoacoustic Tomography (PAT). PAT is an important non-invasive biomedical imaging technique where the optical contrast rendered by laser beams and the superior resolution of ultrasound waves are used to study biological tissues. The new algorithm works better with higher accuracy as compared to the conventional ones in use today.

In 2013, melting of the Chorabari glacier led to heavy floods in Uttarakhand and Himachal Pradesh, causing massive loss of life and property. Glacier lake outburst floods (GLOF) like this, have become a major safety concern in the Himalayas and other mountainous regions across the world. A group of researchers from the Indian Institute of Science, Bengaluru has now developed a unique model that can help prevent massive damages. Led by Prof. Anil Kulkarni at the Divecha Centre for Climate Change, the model serves as a tool for safe planning and timely monitoring of glaciers.

Over the last several decades, antibiotics have played a critical role in fighting infectious diseases caused by bacteria and other microbes. However, blatant misuse and overuse of these drugs has resulted in the bacteria becoming resistant to a wide range of antibiotics where it changes itself to eliminate the action of the antibiotics and thus renders the drug useless. A recent work by researchers at the Indian Institute of Science, Bangalore and the Bose Institute, Kolkata, has addressed the challenge of antibiotic resistance using nanotechnology.

“There is no such thing as ‘away’. When we throw something, it must go somewhere”, said Annie Leonard, a famous critic of consumerism. But what happens around “somewhere” when we throw out our wastes? A recent study by a team of researchers at the Indian Institute of Science, Bengaluru, has analyzed the composition of the water that passes through landfills and has dissolved and suspended matter from it, called leachate, from the infamous Mavallipura landfill and has examined its effects on the nearby lakes and wells. Prof. T. V. Ramachandra from the Centre for infrastructure, Sustainable Transportation and Urban Planning (CiSTUP) and his team have also highlighted the resulting ill effects and suggested some steps to minimize the same.

Researchers have, for the first time, reported in detail a little known source of water among great apes and Old World monkeys – a family of primates that inhabit the forests of Asia and Africa. The team, led by Prof Anindya Sinha of the National Institute of Advanced Studies, Bangalore, observed eight species of great apes and Old World monkeys (belonging to the Cercopithecidae family), drinking water accumulated in tree-holes.
