Two new studies from the Indian Institute of Bombay (IIT Bombay), Mumbai, show the importance of defects in the arrangement of atoms in a crystal, called dislocations, in shaping the physical properties of metallic alloys.
Diatoms — single-celled algae — can be indicators of the health of Karnataka’s rare Myristica swamps
Not more than two decades ago, I played with snails on rainy days and would see them crawling abundantly on plants. My friends and I would collect them in glass bottles, treating them as pets.
It appears that snails have almost vanished from our gardens. Lush green landscapes and trees have dwindled to become a few patches of green separated by tall buildings in between.
Researchers find a greater abundance but an altered epiphyte community in selectively logged forests
Sigur plateau in the Western Ghats may be ideal for a vulture-sanctuary, say researchers.

Thus hath the candle sing'd the moth.
O, these deliberate fools! When they do choose,
They have the wisdom by their wit to lose.

In a recent study, Mr Kamath, now a researcher at Gubbi Labs, Bengaluru, along with Dr Seshadri KS, a researcher at The Madras Crocodile Bank Trust and Centre for Herpetology, Tamil Nadu, has reported the feeding behaviour of Brown mongoose. Though accidental, the study adds knowledge about some previously unknown behavioural aspects of these elusive mongooses. It is published in the Journal of Threatened Taxa.
In a recent study, researchers from Sai Nath University, Ranchi, and Bharathiar University, Coimbatore, set out to quantify the impacts of natural radioactivity on the surrounding environment in the Nilgiris of Tamil Nadu. Their findings have been published in the Journal of Radiation Research and Applied Sciences.
