A walk on the pavement reveals the beauty of ant nests

In a recent study, researchers from the Indian Institute of Science and Education Research, Kolkata, have investigated the nest architecture of a species of Indian ant, called Diacamma indicum.

Patterns of mating interactions in wild zebrafish now unravelled

Animal behaviour studies, which began in the 1970s, had a rocky start as they were viewed as a deviation from biological studies. They try to answer questions relating to why an animal's behaviour differs with different organisms and environmental factors, and the cost-benefits associated with each behaviour. Such studies help to understand not only the biology of the organism but also its ecological role. In one such study, Dr Anuradha Bhat and her group at the Indian Institute of Science Education and Research, Kolkata, have looked at the mating behaviour of zebrafish.

Here’s what scientists aim to gain from Aditya-L1, India’s first mission to the Sun

In 2008, the Indian Space Research Organisation (ISRO) announced Aditya-1, India's first solar mission to study the Sun. This ambitious endeavour, with various indigenously-developed instruments onboard, holds much promise for our scientific community as they expect to unravel the mysteries of our closest star, the Sun. Now renamed as Aditya L1, the data from the instruments onboard are expected to be a treasure-trove of information on the dynamic processes on the Sun's surface and its atmosphere.

Numbers mean strength, in a dog’s world too

A new study by researchers at the Indian Institute of Science Education and Research (IISER) Kolkata, shows that dogs too have developed strategies to coexist with humans, and numbers play a role in it.

Mitochondria kill themselves to protect neurons from an early death

Voluntary movements, like lifting your hand to wave, are executed through precise coordination between different brain areas. Sometimes, due to the loss of neurons in the brain, some individuals cannot coordinate such voluntary movements and are said to be suffering from a condition called ataxia. A type of ataxia, known as the spinocerebellar ataxia, involves the loss of neurons from the spinal cord and cerebellum. These brain areas are responsible for controlling movement and balance.

Study shows zebrafish use visual cues to find food in turbid water

Delhi’s winter haze is infamous for disrupting the air, railway and road traffic. With visibility dropping to near zero on a few days, life-threatening accidents spike during this season. Animals, on the other hand, seem to have a trick up their sleeves—they use sounds or visual cues to help them ‘see’ through low-visibility conditions. But what about fish? Can they navigate through turbid waters? Indeed, says a study by researchers at two Indian Institutes of Science Education and Research (IISERs), Mohali and Kolkata. The researchers have shown, for the first time, how zebrafish find food in turbid waters.
