IISER Mohali finds zebrafish use landmarks for navigation

IISER Mohali researchers have found that zebrafish did overcome the challenges posed by reduced visibility in turbid waters after a month of acclimatisation. They show zebrafish use visual cues to navigate to foraging sites especially when turbidity is high and visibility is low. Turbid to extremely turbid water conditions are quite common in areas where … Continue reading IISER Mohali finds zebrafish use landmarks for navigation

IISER Kolkata: Paper-based electrodes show superior water-splitting efficiency

Researchers at IISER Kolkata have used a paper coated with nickel nanoparticles and model catalysts to split water to produce hydrogen gas. The flexible electrodes recorded 98% water-splitting efficiency and maintained robustness and durability even after more than 10 continuous days of operation. Using paper coated with nickel nanoparticles and model catalysts as electrodes, researchers … Continue reading IISER Kolkata: Paper-based electrodes show superior water-splitting efficiency

Why gulping water quenches thirst

The neural mechanism that signals thirst and the thirst inhibitory neurons which signal to stop drinking have been deciphered. The research unravels how the thirst inhibitory neurons signal to stop drinking based on the speed of intake of the liquid. It responds to intake of only liquids. Wonder why both animals and humans tend to … Continue reading Why gulping water quenches thirst

Diagnosing early-stage cervical cancer using artificial intelligence

Using an artificial intelligence-based algorithm that uses scattered light data from tissues, researchers from IISER Kolkata and IIT Kanpur have been able to differentiate normal and precancerous tissue, and even identify the different stages of progression of the disease within a few minutes and with great accuracy. In vivo studies are now being carried out. … Continue reading Diagnosing early-stage cervical cancer using artificial intelligence

IISER Kolkata’s compound makes drinking water nearly free of fluoride, metal ions

The compound synthesised by IISER Kolkata researchers can reduce copper, mercury, cadmium and iron content in drinking water to below 2 ppb, which is far below the WHO limit for these metals. After 10 minutes of treatment, the fluoride concentration dropped from 10 ppm to 10 ppb. The compound can also absorb a wide variety of oils … Continue reading IISER Kolkata’s compound makes drinking water nearly free of fluoride, metal ions

IISER Kolkata team develops corrosion-resistant, fire-retardant material

The multipurpose hybrid material prevents E. coli growth and is hydrophobic.  Now, paper or other materials coated with a hydrophobic hybrid molecular material synthesised by researchers at the Indian Institute of Science Education and Research (IISER) Kolkata can behave like a lotus leaf and keep the surface clean and water-proof. Besides increasing the mechanical strength … Continue reading IISER Kolkata team develops corrosion-resistant, fire-retardant material

Indian researchers’ novel approach to early diagnosis of retinal diseases

Early diagnosis of certain eye diseases and studying the early progression of the diseases has now become possible, thanks to the work carried out by a team of researchers from three institutes — IISER in Kolkata, L.V. Prasad Eye Institute in Hyderabad and BARC in Visakhapatnam. The researchers used the retinal data captured by a … Continue reading Indian researchers’ novel approach to early diagnosis of retinal diseases

IISER Kolkata makes targeted delivery of cancer drug possible

Targeted delivery of anticancer drugs exclusively to cancer cells and controlled release of the drugs in a sustained manner inside cancer cells has been achieved by a group of researchers from the Indian Institute of Science Education and Research (IISER) Kolkata. Porous carbon nanospheres about 150 nm in diameter and packed with drugs inside the … Continue reading IISER Kolkata makes targeted delivery of cancer drug possible

IISER Kolkata uses human hair to produce cheaper cathodes for solar cells

Researchers at the Indian Institute of Science Education and Research (IISER) Kolkata have used human hair to produce cost-effective, metal-free cathodes for use in solar cells. This is the first instance where a bio-waste-derived electrode has been used as a cathode in a quantum dot sensitised solar cell device. While metal-free cathodes produced in the … Continue reading IISER Kolkata uses human hair to produce cheaper cathodes for solar cells
