New design in thermoelectric devices can increase both output power and efficiency

A significant problem in electronic devices is the generation of heat during their operation. This phenomenon not only leads to the wastage of electric power but can also damage the device. Thermoelectric materials, which convert heat to electricity and vice versa, can be used to turn the generated heat back into electricity, thereby saving power and avoiding overheating of the device.

A new study by researchers investigates how and when calves learn to use their trunks.

A recent study presents a success story of controlling the spread of Kala-azar in Bihar.

A recent study shows how a smartphone-based tool can be effectively turned into an eye-examination device. This device can take not only retinal photos but also detect early signs of diabetic retinopathy.

The big, bright, green-coloured Andaman day gecko is a sight to behold; only that, you have to go all the way to the Andaman Islands to get a glimpse of it. Endemic to the islands, these geckos live in trees and are active during the day. Thanks to cash crops grown on these islands today, they can be found in plenty, feeding on bananas, coconuts and betel nuts. They belong to the genus called Phelsuma, believed to have evolved from Madagascar, an island about 6000 km away from the Andamans! A new study has traced their evolutionary history and has thrown some light on how they differ from the other geckos in the Andamans.

People see human-animal conflicts as a fight between two species on opposing sides. However, in reality, the human aspect also has multiple dimensions. In some cases, there are two groups—the affected public—and the forest department staff, who manage and mitigate it; in others, more such groups. One of the frequent human-animal conflicts is that between humans and monkeys, especially the rhesus macaque, whose population is widespread in many cities. Now, a study by researchers shows that differences in people's opinions on mitigating such conflicts could instead be adding to the conflict.

In a recent study, researchers show how cleaner air during the lockdown in Delhi, one of the most polluted cities in the world, has led to a hike in solar power generation.

In a recent study, researchers have assessed how successful computer simulations are in matching with solar surface observations.

Researchers use new self-assembly techniques to create microstructures that can be used in early detection of Alzheimer’s disease.
