The “Eyes” Have it: Demystifying Gaze and Attention
01 Mar 2024 under Focus
Two new studies from the Centre for Neuroscience (CNS), Indian Institute of Science (IISc) explore how closely attention and eye movements are linked, and unveil how the brain coordinates the two processes. Attention is a unique phenomenon that allows us to focus on a specific object in our visual world, and ignore distractions. When we […]
Cracking the Structure of a Crucial Neural Transport Protein
13 Jul 2023 under Highlights
Using Cryo-EM, a powerful microscopy technique, researchers at IISc and collaborators have decoded the molecular architecture of a transporter protein controlling the movement of a key neurotransmitter. Neurons or nerve cells communicate by releasing chemical signals called neurotransmitters. Each neurotransmitter can activate specific sets of proteins called receptors that in turn either excite or inhibit […]
Computational analysis shows how dengue virus evolved in India
08 Jun 2023 under Focus
A multi-institutional study on dengue led by researchers at IISc shows how the virus causing the disease has evolved dramatically over the last few decades in the Indian subcontinent. Cases of dengue – a mosquito-borne viral disease – have steadily increased in the last 50 years, predominantly in the South East Asian counties. And yet, there are […]
Neuromorphic Camera and Machine Learning aid Nanoscopic Imaging
21 Feb 2023 under Focus
In a new study, researchers at IISc show how a brain-inspired image sensor can go beyond the diffraction limit of light to detect miniscule objects such as cellular components or nanoparticles invisible to current microscopes. Their novel technique, which combines optical microscopy with a neuromorphic camera and machine learning algorithms, presents a major step forward […]
Record-breaking Radio Signal Detected from Distant Galaxy
16 Jan 2023 under Focus
Astronomers from McGill University in Canada and IISc have used data from the Giant Metrewave Radio Telescope (GMRT) in Pune to detect a radio signal originating from atomic hydrogen in an extremely distant galaxy. The astronomical distance over which such a signal has been picked up is the largest so far by a large margin. […]

Plasma‐activated-water to Combat Multidrug‐resistant Pathogens
29 Dec 2022 under Highlights
Researchers from IISc have demonstrated the generation of plasma-activated water containing reactive oxygen and nitrogen species such as H2O2, NO2−, and NO3− in high strengths (hs-PAW). This hs-PAW was found to be capable of inactivating even hypervirulent multidrug resistant pathogens. The study, led by Lakshminarayana N Rao and Dipshikha Chakravortty, also shows that plasma-activated water […]
Protein synthesis in cells without a nucleus
29 Dec 2022 under Highlights
Translation, or protein synthesis, is the final step in the central dogma of molecular biology, where an mRNA carrying information from DNA synthesises proteins. It is an indispensable process that is performed by almost all living cells. An exception where translation was believed to be absent is red blood cells (RBCs). Now, a team led […]
Enhanced water evaporation from nanoporous graphene
29 Dec 2022 under Highlights
With growing global water stress, there is a pressing need to develop potable water technologies with a lower carbon footprint. Enhancing the kinetics of liquid–vapour transition from nanoscale confinements is an attractive strategy for developing evaporation and separation applications. The ultimate confinement limit for evaporation is an atom-thick interface hosting Angstrom-scale nanopores. Researchers led by […]
In the Wake of a Cylinder at Mach 6
29 Dec 2022 under Highlights
Air gusts or currents in the wake of a fast-moving object like a car or truck is a common phenomenon that many among us have experienced. In such ‘wake flows’, air typically moves around in an unsteady and whirling manner. This motion of air presents very interesting patterns in space, with a certain associated periodicity […]

Compact Nanopositioning Stages with Large Range and Multiple Degrees of Freedom
12 Aug 2022 under Highlights
Precision positioning stages are often central to science and technology at the micrometer and nanometer length scales in diverse fields such as microscopy, robotics, automation and metrology. These stages are used to hold in place, or move in a specified manner, a piece of equipment or a sample. Therefore, compact multi-degree-of-freedom stages with large dynamic […]
